| Title: Advanced Finite Element Model Development for Characterization and Mitigation of Bone Conducted Sound Transmission in High Noise Environments | |
| Abstract: Improved characterization of the dominant paths of bone conducted sound transmission caused by external acoustic excitation for a person wearing a plug/earmuff combination is urgently needed for development of effective hearing protection in extremely high noise fields. This two phase program will achieve this ambitious goal through the extensive use of computer simulation techniques which are supported by bioacoustic and psychoacoustic experimental validation. The proposed research will develop an advanced finite element (FE) model of a human head with the important internal components necessary for simulating bone conduction, including the auditory system. An experienced team of experts in bone conduction, auditory mechanics, and finite element modeling has been assembled, including the Oto-Biomechanics group from Stanford University. The group's expertise in the modeling of auditory systems will be combined with the modeling of hearing protection systems offered by ATI. Phase I research will focus on the development and validation of FE models for the middle ear and the skull which are considered to be the critical components in bone conduction mechanics. These component models will be integrated into a whole head FE model during the Phase II research effort. | |

| Title: Exploiting Microstructural Evolution for Material and Damage State Sensing | |
| Abstract: The objective of this project is to develop a multi-purpose combination type optical fiber sensor that enables simultaneous sensing of microstructural evolutions in the sensor materials and the environmental conditions such as pressure and temperature. It is very well known that materials subjected to fatigue and high temperature will go through microstructural changes such as plastic deformation, grain coarsen, precipitation generation, phase transition, and surface roughening. While extensive researches have been conducted to develop non-destructive detection techniques to measure these microstructural changes using ultrasonic wave, most of these techniques excite acoustic wave in the service components directly and therefore require high power excitation sources and bulky detection units. To overcome these difficulties, the proposed sensor measures the microstructural changes of a sensor material that is subjected to the same operational conditions as the service components do. The microstructural evolution of the sensor material is then used to interrogate the damage state of the service components. The proposed sensor is a stand-alone sensor probe combining laser-acoustic, laser scattering, and optical fiber interferometric sensing techniques to measure the material microstructure. In addition to its capability to measure multiple physical parameters simultaneously, the optical fiber sensor also has the advantages of being compact, lightweight, remotely operational, capable of operating in harsh environments, and immune to electro-magnetic interference. | |

| Title: Polymer-ceramic Nanocomposites for High Power Capacitors | |
| Abstract: We propose to develop new polymer-ceramic nanoparticle composites for high power capacitors. The new approach combines the leading-edge nanomaterials development and manufacturing at Agiltron will transfer the high dielectric constant fillers to our new nanodielctrics with extremely improved breakdown strength and extensively lowered dielectric loss. We expect to fully overcome the problems of current techniques by creating a high dielectric constant interphase region around filler particles and by using low filler loading to accomplish improvements in capacitors that are orders of magnitude improved over current devices. Our nanocomposites will have a dielectric constant 2 to 3 orders of magnitude higher than that of polyimide, a breakdown strength 2-3 times higher than that of polyimide, and dielectric loss lower than 0.01. Importantly, our nanodielectric films will be flexible due to the low filler loading, and they can be folded and rolled like plastic sheets to build compact capacitors. The goal of the proposed program is to develop new nanocomposite films for high power capacitors. The proposed dielectric films will be flexible, and thermally stable with high dielectric constant (hundreds to thousands), high breakdown strength, and low loss. | |

| Title: ADAPT: Allocation of Dynamic Attention across People & Teams | |
| Abstract: Effective task management is a critical component of mission success. As warfighters are given more information to monitor, however, their ability to detect and attend to critical information and tasks is stressed. An automatic task manager is needed to help ensure that responses to events occur in a timely manner. The foundation of such a tool is an accurate model of human dynamic attention. Many such models have been formulated; however none describe behavior in a command and control (C2) environment. We propose to (1) develop a model of dynamic attention in a representative C2 environment, the Dynamic Targeting Cell (DTC); and (2) develop an automated task manager that leverages this model. ADAPT will automatically inform warfighters of tasks that need to be performed. This advice will be optimized to reduce attention shifts and attentional overload and ensure that critical events are covered. When complete, ADAPT will increase the effectiveness of teams within the C2 environment, ensuring that tasks are attended to efficiently and effectively. | |

| Title: CIFTS:Communications and Information Flow Tracking System | |
| Abstract: Electronic text chat has become a primary medium of communication throughout the military over the past fifteen years. In organizations such as the Air and Space Operations Center's Dynamic Targeting Cell (DTC), it is used extensively among team members as they collaboratively process information about time sensitive targets for prosecution. To assure the highest degree of performance, operators undergo periodic training. Training effectiveness is maximized by providing performance measurement and feedback to operators, so they can learn from their actions and errors. However, identifying reliable performance indicators is difficult. CIFTS, the Communications and Information Flow Tracking System, will provide performance measures based on patterns of communications flow and models of communications content. These measures will be correlated with external performance measures (e.g., expert ratings, outcome measures) to validate their utility for non-obtrusive performance assessment. The resulting system will improve the team performance assessment capabilities in the DTC by leveraging a largely untapped source of performance data: inter-personal communications. CIFTS has wide application in military organizations that utilize chat, including multi-vessel Naval operations and intra-brigade communication in the Army. Lessons learned from a deployed CIFTS system will increase the knowledge base in the team and organizational performance research area. | |

| Title: Integrated Visual and Inertial Sensor Information for Onboard Navigation (I-VISION) | |
| Abstract: Given the vulnerability of the GPS system to intentional or hostile denial of service, it is imperative that the U.S. military develop technologies that provide robust navigation solutions that do not rely on GPS data. To achieve this capability, Aurora and MIT have teamed to develop the Integrated Visual and Inertial Sensor Information Onboard Navigation (I-VISION) system, which will couple optic flow-based ego-motion estimation with inertial navigation systems to achieve precision navigation without GPS.. Current-generation inertial measurement units (IMUs) provide very accurate angular rate and linear acceleration information, which can be integrated to estimate a platform's position, velocity, and orientation over time. Unfortunately, due to sensor biases and scale factor errors, the accuracy of the estimation degrades with time. The coupling of visual flow and IMU-based ego-motion estimation enables the IMU to aid in resolving vision-based errors and ambiguities, and visual flow estimates can be used to reduce IMU sensor biases and scale factor errors. A multiple-camera system will be considered in order to better address the ambiguity that is introduced in the estimation of optical flow-based ego-motion. Both tightly coupled and ultra-tightly coupled implementations will be considered. | |

| Title: High-Power Millimeter-Wave Micro-Sources for Communications & Radar Dominance | |
| Abstract: The proposed effort is to evaluate the feasibility of a W-band sheet-beam vacuum electronic device that can provide up to 1 kW of peak RF power at a minimum efficiency of 20%. Key elements of this effort are on the generation and transport of the sheet beam and its interaction with the RF circuit. The potential of employing a depressed collector to improve overall efficiency will also be investigated. As part of this effort, a proof-of-principle expreriment will be performed in the Phase-I to demonstrate the potential of the miniature plasma gun as a sheet-beam electron gun. Fabrication techniques will also be evaluated based on optimized beam and circuit parameters. The overall goal of this work is to define a Phase-II development strategy that is innovative yet based on achievable fabrication methods and tolerances. | |

| Title: Random Radar | |
| Abstract: Black River Systems Co., Inc. and Syracuse Research Corporation propose to develop a portable self-contained sensor, of size consistent with carriage and operation by a single airman, mounting on a pickup truck or a C-130 aircraft, capable of standoff sense-through-the-wall detection and location of humans and mapping their surroundings in real time. The key discriminators of the proposed baseline approach are: 1) an ultra wideband (UWB) random noise based transmitter with high-resolution coherent, correlation-type digital receiver, 2) a moving target detector to detect and locate very small movements of potential targets, 3) an image processor to image buildings and contents, providing real time situation awareness, and 4) covert and jam proof operation. Advanced features such as exploitation of model-based deconvolution and phenomenology, advanced imaging techniques, coherent and non-coherent clutter suppression, jamming/RFI suppression, covertness and ultra-wideband waveform diversity for long range standoff operation providing real-time, dynamic, and accurate information will be studied. Each trade will balance detection, image quality, speed, covertness and jamming resistance with system size, weight, power and cost. A Phase II program plan for development and test of a prototype system leading to high fidelity estimates and critical laboratory tests of proof-of-the-fundamental principles will be developed. | |

| Title: High-Resolution Wide-Dynamic-Range MEMS-Based Closed-Loop Adaptive Optics System | |
| Abstract: Block MEMS, LLC (Block) and the University of North Carolina at Charlotte (UNCC) are proposing a unique approach to wave front processing and correction using an adaptive optics deformable mirror (DM) technology. The key technical challenges involve a DM that has one million pixels, each moving vertically up to 40 microns at a frame rate of 100 kHz. Not only does this present a challenge for the microelectromechanical system (MEMS), but it presents an even greater challenge for the wavefront/image-processing system. We propose a Fourier optics approach to wavefront monitoring and sharpness correction and a state-of the-art MEMS mechanism based on the Sandia Labs SUMMiT-VT MEMS fabrication process. The Fourier optics approach eliminates the need to process one million pixels in the traditional matrix multiply fashion, as this traditional approach could not process the correction at the100 kHz rate. In contrast our approach needs only to maximize a single image-sharpness metric using an iterative algorithmic approach that we contend is achievable at the 100 kHz rate. | |

| Title: Coaxial High Energy Thruster for Rapid Maneuvering of Space Assets | |
| Abstract: Busek Co. Inc. and Stanford University propose to jointly develop and test a high power plasma propulsion concept called the Coaxial High EnerGy (CHENG) thruster. This high efficiency (> 85%) pulsed system will be capable of average thrust levels commensurate to chemical propulsion (10^4 N/m^2), but with an Isp comparable to electrostatic propulsion (4000-50,000 s). Both thrust and Isp will be variable. The concept was originally demonstrated in the early 1970s, but was never fully characterized. Subsequent developments in high speed pulsed gas valves and pulsed power technology implore revisiting the concept. In Phase I, we will demonstrate a 12 kW thruster at firing rate of 4 Hz, producing an average thrust density of 103 N/m^2. In the process, we will identify key requirements for validating the technology, develop our approach to Phase II, and identify dual-use and commercialization potential. In Phase II, 12 kW performance will be measured on a thrust stand. Then the thrust density will be extended to 10^4 N/m^2. This will entail building a 50 kW, 100 Hz thruster. Throughout both phases, numerical simulations will be used to study the physics of the discharge and its impact on thruster erosion rates, believed to be very low. | |

| Title: A High Current Microfabricated Carbon Nanotube Field Emitter Array with Ballasting | |
| Abstract: High current density carbon nanotube-based field emission arrays with uniform emission will be developed under this program. Working in conjunction with MIT, microfabrication techniques will be used to produce high density arrays of CNT emitters on substrates which incorporate feedback to ensure uniformity of emission between emitters. The feedback techniques employed will minimize thermal effects and will not result in excessive thermal loads. Modeling of this device will be performed to optimize the fabrication parameters to enhance uniformity of emission. During Phase I some test devices will be fabricated which can emit currents up to 100 microamps in an area 1 mm square. These devices will be characterized for emission uniformity in order to verify that the feedback system is performing as expected. The goal for Phase II is to develop devices capable of emitting at least 1 amp over an area of 1 cm^2. | |

| Abstract: This proposal contains innovative, traveling-wave tube (TWT) designs compatible with three-dimensional (3D) micro-electro-mechanical systems (MEMS) fabrication techniques for millimeter-wave applications. The development will focus on novel planar interaction circuits; long life, high current density electron guns; and compact magnet configurations. The ultimate goal will be high power, efficient, compact, lightweight, and affordable RF sources. The batch nature of MEMS fabrication provides repeatability of components for increased yields and reliability, and reduced cost. The Phase I effort will use advanced, state-of-the-art simulation tools to design a 95 GHz traveling wave tube providing 100's of watts of peak power. We will thoroughly investigate the interaction circuit for its thermal and electrical performance, including bandwidth and efficiency. In addition, the program will design major TWTA components, including the electron gun and focusing structure. In parallel, we will explore MEMS fabrication techniques to integrate several TWT components into the fabrication process to avoid assembly and alignment procedures, which become increasingly difficult at higher frequencies. Continuing work will include fabrication and testing of a 95 GHz, miniaturized TWT with the goal of fabricating the entire system by MEMS techniques for "TWT on a chip" technology. | |

| Title: Stability Models for Augmentor Design Tools and Technology Assessment | |
| Abstract: We are proposing a joint experimental/modeling and computational study to develop stability models for CFD codes to design advanced augmentors. Experiments will be conducted at the Research Institution to address various issues related to augmentor stability under vitiated conditions. A stream of vitiated air will be established within an existing vertical wind tunnel. Fuel jets in crossflow and bluff body stabilized jets will be placed into this stream. Available state-of-the-art measurement instruments and visualization techniques will enable us to study the role of vitiation and bluff body shedding upon the jet mixing, flame stabilization, and the downstream jet development. Moreover the effects of changes in altitude will be imitated and studied by varying the jet to momentum crossflow ratio. At our firm, a highly sophisticated, fully unstructured, multi-physics LES code for compressible turbulent combustion already exists. A newly developed auto-ignition model will first be extended for vitiated combustion conditions, and then validated against Cabra et al.'s detailed experiments of reactive flows in vitiated environments. Next, LES simulations of augmentor type geometries will be performed and validated against data from the Research Institution. Using experimental and simulation results, reduced stability models and novel flame holding concepts will be suggested and evaluated. | |

| Title: Novel Volume of Solid Technology for Nonlinear Aeroelastic Stability Analysis | |
| Abstract: Morphing technology enables aerospace vehicles to achieve a broader range of operational modes. Computational aeroelastic and design analysis tools of these vehicles must be able to handle arbitrarily large deformations and shape changes. Innovative Volume of Solid technology is proposed to cast structure/body-dynamics equations in an Eulerian reference frame, preserving the order of accuracy of the fluid and structural differencing methods. In this technology, a unified equation is derived, which requires no moving mesh or grid generation, and imbeds all the interaction forces between fluid and solid. Typical CFD codes may adapt this technology through addition of source terms related to the body motion and by changing effective areas. The technology is especially designed for arbitrary large and quick shape change and deformation in nonlinear aeroelasticity analysis. The developed modeling technology will provide more accurate descriptions of the aerodynamic forces placed on aircraft wings. In Phase I, an in-house multi-physics code will be modified to include the structure/body dynamics in an Eulerian frame. The technique will be evaluated for a telescoping wing case. An existing MEMS-instrumented flapping wing experimental test will be adapted to provide data model validation, A complementary computational-experimental study is planned for Phase II. Future validation, verification and simulation of realistic morphing air vehicle concepts, and its implementation in other DoD CFD codes will be carried out in Phase II. | |

| Title: Optimized Quantum Dot Superlattice Structures for Ultra-High Efficiency Photovoltaic Cells and Photodetectors | |
| Abstract: Higher efficiency solar cells are needed to reduce solar-array mass, volume, and cost. In this project we propose to develop: (i) a concept of the novel quantum dot superlattice (QDS) solar cells, which are estimated to be more efficient and radiation tolerant than conventional multi-junction solar cells, (ii) new computational tools for the quantum-dot nanostructure optimization for the specific applications. The developed models will be validated with experimental data from the Nano-Device Laboratory, UCR. It is anticipated that QD solar cells can achieve efficiencies of ~60% via optimization of the light absorption ("multicolor" effect via dot-size tuning), optical selection-rules relaxation and confinement-induced changes in the carrier transport (mini-band formation) and phonon dispersion. The user-friendly 3D modeling tools, to be developed at CFDRC, will be used for the QDS optimization for both photovoltaic and photodetector applications. Specific issues to be addressed include: (i) quantum dot ordering and size dispersion, (ii) enhanced photogenerated carrier separation and drift mobility; (iii) improved electric conductivity and increased collection efficiency. Phase I includes development of the numerical models for QDS and their experimental validation with prototype QDS. In Phase II we will use the developed modeling tools for the radiation-hardness optimization of QDS-based solar cells and detectors. | |

| Title: Novel Stability Model and Flameholder Concept for Modern Augmentors | |
| Abstract: Static stability is a major challenge for modern augmentors that feature close-coupled fuel injection/flameholders operating at low pressures and high inlet velocities, inlet temperatures and vitiation levels. Reduced dilatation and baroclinic vorticity effects at augmentor conditions cause large scale von Karman vortices to dominate the blowout event, in contrast to conventional bluffbody shear layer blowout theory. In this Phase I/II STTR, CFDRC and university partner Georgia Tech propose to: 1) better understand the physics involved in blowout at modern augmentor conditions, 2) develop reduced-order stability/flame transfer models based on this improved understanding, and 3) investigate improved flameholder designs. In Phase I, we will focus on understanding blowout physics at augmentor conditions by performing combustion Large Eddy Simulations (LES) of a generic configuration, and validating the predictions against AFRL HIT experiments. Using results from LES, the basic structure of a vorticity-based blowout model will be formulated that captures the effects of kinetics and transient strain rate on the blowout event. In addition, blowout experiments will be performed to test a novel flameholder that potentially eliminates von Karman vortices and improves stability. In Phase II, the reduced-order model will be further expanded to include submodels (e.g., for fuel/air nonuniformity, velocity gradients, cooling flow, spray, etc.), and thoroughly validated.

| Title: New Methods of Controlling Electron Kinetics and Plasma Chemistry in Pulsed Discharges of Electronegative Gases | |
| Abstract: A number of modern technologies utilize unique properties of highly non-equilibrium plasmas produced by electric discharges in molecular gases. Electron kinetics and vibrationally excited molecules define key chemical reactions in these plasmas. The goal of this project is to utilize the non-local nature of electron kinetics to improve the performance of various plasma devices under pulsed power conditions. In Phase I, the analysis of electron kinetics and vibrational kinetics will be performed for the high-pressure conditions present in the Electric Oxygen-Iodine Laser (EOIL), and for the low-pressure conditions typical to material processing reactors and MHD generators. The role of runaway electrons and nonlocal ionization in the active phase, and the role of vibrational excitation and fast electrons generated in chemical reactions in the passive phase will be investigated using computational tools developed at CFDRC. Different methods of tailoring the electron distribution function and vibrational distribution function for efficient production of singlet delta oxygen (SDO) and dynamics of negative ions (facilitating electron detachment) will be investigated via analytical models and computational experiments. The Ohio State University will provide expertise in non-equilibrium vibrational kinetics and plasma chemistry, and experimentally demonstrate the effect of fast and non-local electrons in Phase II. | |

| Title: Rapid Evaluation and Analysis of Communication in Teams (REACT) | |
| Abstract: In a Net Centric Battlespace, information is constantly shared along both formal and informal channels. Informal means of communication such as chat rooms are often employed when standard channels of communication do not fit the emergent work practice of a group. Despite its inefficiency, this unstructured communication is very natural and convenient for users. As such, it is a rich and plentiful data source for understanding group interaction. However, existing methods for analyzing such discourse are either low-fidelity (simple keyword matching) or extremely man-power intensive (manual transcription and tagging). With advances in speech recognition, part-of-speech tagging, and social networking theory, it is possible to improve on these discourse analysis techniques and use them to model an interaction. One primary output of this model is the performance of individual team members, and of the team as a whole. Such measures can be used to highlight areas of reduced performance or possible breakdown within a large team. We propose to develop a system for Rapid Evaluation and Analysis of Communication in Teams (REACT), combining traditional techniques from discourse analysis with advances in NLP and communication analysis. REACT rapidly analyzes streams of communication to highlight potential areas of coordination difficulty. | |

| Title: Enhancing IPB with Representations of Meta-information (EPROM) | |
| Abstract: Modern military operations increasingly require decision-makers to reason predicatively about adversary actions and the battlespace environment - a task made more challenging due to meta-information (i.e., qualities of information such as uncertainty or staleness). Understanding the role of meta-information in reasoning about intelligence and developing methods for effectively portraying it has the potential to improve the interpretation and dissemination of intelligence and therefore to encourage more battlespace-aware decisions. Therefore, we propose to design, demonstrate, and evaluate methods for Enhancing IPB with Representations Of Meta-Information (EPROM). Three core components characterize our approach. First, we will perform a work domain analysis (WDA) in a specific military domain to define the perceptual and cognitive contexts that impact the role of meta-information in reasoning, and develop case studies to illustrate these impacts. Second, we will design meta-information visualization methods that explicitly address the defined contexts illustrated in the case studies. Third, we will develop a plan for evaluating these visualization methods and will perform pilot experiments to validate our approach. Our approach will be supported by the design of a software toolkit to aid in prototyping and evaluating visualization methods, and by the integration of these methods into existing and planned DoD battlespace display systems. | |

| Title: Quantitative Model of Human Dynamic Attention Allocation | |
| Abstract: The objective of this proposal is to demonstrate the feasibility of a quantitative dynamical model of human attention and perception. Recent experimental findings have demonstrated the importance of event timing for perceiving and attending to complex sequences of events: 1) The auditory system uses active temporal mechanisms for analysis of sound from the earliest stages of sensation through the development of integrated high-level percepts; 2) Attention exploits temporal stimulus structure to coordinate perception, cognition and action in a way that is optimal for a given task environment. In both cases, the nervous system exploits nonlinear oscillation to encode and interact with complex stimuli that unfold over time, albeit over different time scales. Analysis and interaction with temporal stimuli via networks of nonlinear oscillators is referred to here as nonlinear time-frequency transformation. This proposal is to develop a nonlinear time-frequency transformation software toolbox, and to evaluate its utility as a model of human attention and perception. Evaluation will include 1) analyses of temporally complex data streams 2) analysis of data streams from multiple sources (spatial locations or perceptual modalities) and 3) production of attentional expenditure estimates for a human confronted with such a data stream in a complex task environment. | |

| Title: TEMBOr Foam for Morphing Wing Applications | |
| Abstract: In recent years there has been significant interest in developing morphing air vehicles that would be able to fly efficiently over a wide range of flight regimes to meet new mission profiles. Though morphing-wing concepts have been around for many years, it has been determined that conventional designs such as swing wings are not adequate for providing the desired improvements. Many of the new morphing wing concepts that have been developed have rigid but articulating substructures that rely on flexible skins to provide the aerodynamic surface. Because of the difficult requirements, the skin is often a limiting factor in the realization of morphing concepts. Composite Technology Development, Inc. (CTD), working with the Georgia Tech Research Corporation, proposes to use a new type of shape memory polymer (SMP) for morphing wing skin elements. Key goals of the program are to define material property requirements from system-level requirements provided, to experimentally and analytically characterize the performance of the SMP, and to design and test a preliminary wing skin element. | |

| Title: Novel Experimental and Numerical Methods for the Aeromechanical Design of Flapping Wing Hovering MAVs | |
| Abstract: Recent developments have made clear the strong potential of Micro Air Vehicles (MAVs) for a wide range of surveillance and tactical reconnaissance functions, particularly if the challenging but critical hovering capability can be achieved. Implementation of a practical hovering air vehicle at very small scales, however, requires breakthroughs in understanding of the complex flow environment of such vehicles as well as development of practical design and analysis tools for this regime. The proposed effort will support these objectives by advancing the fundamental understanding of the relationship between wing kinematics and forces - including low Re and wing flexibility effects - with the ultimate goal of developing aerodynamic/aeroelastic models for use in simulation and design. This will permit generation of viable aerodynamic flight control schemes for flapping wing MAVs operating in gusty conditions. The effort will build on mutually supporting capabilities of the team members, and will feature application of a suite of both established and evolving computational modeling tools for complex vortex-dominated flows at low Re as well as use of advanced experimental methods for flow diagnostics and aeroelastically scaled models. The project will also leverage a strong foundation of experience in support of design software for vertical flight vehicles. | |

| Title: Bone-conducted Sound Transmission and Attenuation | |
| Abstract: Hearing protection for personnel working in high-noise environments remains an important challenge for the scientific and engineering community. The sound levels close to certain modern military weapons platforms approach 150 dBA. At these levels, the attenuation provided by hearing protection devices (HPDs) is limited by bone-conducted sound that bypasses the ear canal and its associated protection (earplugs and earmuffs). An improved understanding of the transmission mechanisms for bone-conducted sound is required to enable the design of improved active and passive hearing protection devices. Creare and the University of Illinois propose a three-pronged approach to investigate the transmission of bone-conducted sound and design-improved HPDs. The approach involves (1) calculation, using an acoustic wave propagation model implemented in finite element analysis software; (2) simulation, using an instrumented physical model of a human head; and (3) human subject tests, investigating the nonlinear response of the cochlea to bone conduction stimulation. In Phase I we propose to demonstrate the feasibility of each of these techniques, and in Phase II we will conduct a detailed investigation of the phenomena using these techniques and apply the results to the next generation of hearing protection devices. | |

| Title: Self-Healing Adhesives and Composites for Aerospace Systems | |
| Abstract: Self-healing composites and adhesives would alleviate longstanding problems in aerospace structures associated with multiple types of damage mechanisms such as mechanical/thermal fatigue, microcracking, and debonding. A composite cryogenic tank based on self-healing technology would prevent leakage by sealing microcracks throughout the lifetime of the tank and enable the use of composites in this critical application with low risk to mission success. In Phase I, the feasibility of self-healing structural composites and adhesives will be demonstrated by incorporating microencapsulated healing agents and chemical catalysts in composite systems and measuring their mechanical performance under a variety of loading conditions. A partnership between CU Aerospace (CUA) and the University of Illinois at Urbana-Champaign (UIUC) has been formed to pursue the aerospace applications of this new technology. Together, we will demonstrate the technology for laboratory scale mechanical test specimens and quantify healing performance under both static and cyclic fatigue conditions. This technology is critical not only to STSS, ABL, and a variety of other Air Force mission objectives, but is fundamental to all aerospace structural composite applications. | |

| Title: Communication Analysis for Enhanced Team Performance in the AOC | |
| Abstract: Improving team communication in distributed C2 environments must start with addressing underlying components of communication problems. First, it is important to understand what defines "good" communications (e.g., domain-specific frequencies, types, shifts from explicit to implicit communication) and what communications, or lack thereof, contribute to breakdowns. By neglecting the examination of these influences on team communication, data interpretations remain ambiguous, possibly misrepresentative. Next, it is important to know when communication failures occur to monitor and measure team performance. Finally, communication analyses must consider why errors occur (i.e., information is not exchanged, received, correct, or comprehended). The measurement of these cognitions will be described via state-of-the-art EEG and eye tracking metrics to assess the reasons for communication failure. To address these issues, this effort proposes to develop a Multi-axis APproach to Measuring and Interpreting Team Communications (MAP IT-C), a conceptual model which describes: 1) the process to develop a Predictive Framework driven by task analysis and social networks analysis, and 2) the specifications for Real-time Communication and Performance data collection and 3) an Online Diagnostic Engine used to diagnose team performance real-time (i.e., mapping a comprehensive suite of metrics [communication, physiological, and behavioral metrics] against expectation data generated from the Predictive Framework). | |

| Title: Nanotube Transparent Electrodes for Nanomaterial Photovoltaics | |
| Abstract: Eikos Inc. and the National Renewable Energy Laboratory propose to develop nanomaterial transparent electrodes to enhance the efficiency of three junction solar cells. Eikos leads the world in developing transparent conductive electodes based on carbon nanotubes (CNTs). Branded as Invisiconr, our patented technology has already been successfully employed to improve solar cell performance. Eikos collaborates with the National Renewable Energy Lab and leading companies to fabricate organic, CIGS, and other solar cells incorporating Invisiconr for military and commercial applications. Having demonstrated our ability to integrate into a wide variety of solar technologies, we now propose to integrate Invisiconr into three junction very high efficiency solar cells as a transparent electrode. Carbon nanotube electrodes will reduce shadowing from the metal grid and will allow the AlInP layer to be thinned, while improving carrier transport and acting as an anti-reflective coating. CNT coatings are exceptionally transparent through the visible and into the infrared, improving efficiency of future four junction solar cells. Invisiconr will ease manufacturing tolerances and lower PV production cost by improving the cell performance at minimal added cost, making multi-junction PVs more attractive for terrestrial concentrators. Nanotubes are exceptionally stable at high temperatures and under intense irradiation, making them ideal materials for space applications. High performance solar cells with Invisiconr will have improved theoretical efficiencies at reduced cost, which will make them the new standard for space applications and open emerging markets for terrestrial applications. | |

| Title: Reconfigurable Nanophotonic Optical Interconnects for Advanced FPGAs | |
| Abstract: Optically interconnected systems provide a number of additional benefits. For example, by removing metallic traces, many signal integrity issues are also eliminated as the parasitic capacitance and inductance associated with high-speed lines are removed, which further improves systems performance. Additionally, such systems typically require less power and experience less leakage, or wasted power, which is critical in space-borne applications. Moreover, an optical system is immune to the standard radiation effects of the harsh space environment. To this end, we propose the development of an optically reconfigurable nanophotonic interconnect for advanced FPGA. By removing the electrical interconnections between logic blocks, data can be quickly and efficiently routed across the FPGA. Such a novel design will remove the routing bottleneck associated with existing FPGA architectures and enable the rapid development of high performance FPGA systems. | |

| Abstract: The protective properties of the oxide films that form on aluminum alloys can break down locally and allow extensive corrosion. An amorphous alloy system recently developed at the University of Virginia is promising as an environmentally compliant metal cladding. We propose a new method for converting alloy powder into coatings. This technique does not require large standoffs and has very high heating and cooling rates, which prevents grain growth and result in deposition of amorphous material. The substrate remains at low temperature during deposition. | |

| Title: Environmentally-Benign Oxidizers for Propulsion | |
| Abstract: Ammonium perchlorate (AP) is the most commonly used oxidizing ingredient in solid propellant formulations. It carries a sufficient excess of oxygen to allow for the combustion of the required binder and added metal, such as aluminum. One major drawback of AP is its chlorine content which results in the formation of hydrochloric acid (HCl) as a combustion product and can cause environmental problems. Available halogen-free oxidizers, such as ammonium nitrate (AN) or ammonium dinitramide (ADN) provide less available oxygen, than AP and, therefore, result in significantly reduced performance of their formulations. A second major drawback to AP is its high solubility in water (20g/100g water at 0C) and subsequent contamination of ground water. Further, it is highly mobile and persistent in ground-water systems. An objective of the Phase I STTR program is to conceive potential candidate compounds and screen them based on their theoretical performance and other parameters. Experimental approaches to synthesize and characterize promising new ingredients will be designed. Ideally, sufficient amounts of target compounds will be prepared to allow determination of structure and permit necessary ingredient stability and sensitivity tests to be conducted. If the reaction scheme is complex, performance on Phase I may be limited to demonstration of feasibility of the key steps. | |

| Title: Diamond Studded Micro Helix TWT | |
| Abstract: A highly efficient, very wide bandwidth, diamond studded micro helix TWT for operation at 95 GHz will be designed and fabricated by means of a novel application of solid state micro fabrication technology. Because of the nature of the fabrication process proposed here, this device can be built as a single TWT or just as readily as an array of TWTs. By spatially combining the power output of several TWTs in an array, an electronically steerable power output of hundreds of Watts is quite feasible. The design will be conducted utilizing well established computational techniques first introduced by the authors and now widely adopted. The fabrication of the micro helix TWT will rely entirely upon lithography and other solid state techniques. Because this fabrication technique results in a helical circuit that is supported by a minimal amount of low permittivity dielectric, it is anticipated that the bandwidth and efficiency will be much higher than for a conventional helix. | |

| Title: Exploiting Raster Maps for Imagery Analysis | |
| Abstract: Maps are an incredibly rich source of information, but the information contained in a map is often locked up in a raster image. Sometimes the original source data used to create the map is available, but more often than not this information has either been lost or is not available. In the proposed project, we propose to develop the technology that will make it possible to exploit the huge number of raster maps available and use them for imagery analysis. In particular, we will develop the technology for automatically finding online raster maps, automatically aligning the raster maps with satellite imagery, and automatically extracting the information contained in a maps, such as transportation networks, hydrographic layers, and the textual labels on the information. The resulting technology will allow an analyst to view a satellite image for any place in the world, automatically find and align the maps covering that region, and then overlay selected layers from the map to better understand the information shown in an image. | |

| Title: Exploiting Microstructural Evolution for Material and Damage State Sensing | |
| Abstract: The purpose of the proposed STTR project is to develop a high temperature and aggressive environment-operating structural health monitoring (SHM) sensor based on micro-structural evolution concept in the sensor material. The objective of the proposed STTR project is to develop a step-forward multi natured measurement (MNM) PWAS sensor architecture that takes advantage of both conventional and exotic structural evolutionary approaches towards quantification of specific degradation states, failure modes and usage conditions, and that is potentially applicable for remaining useful life (RUL) prognosis of jet engine components. The proposed STTR proposal outlines several materials of interest, environmental subjection properties that will be explored, and the first approach is exploiting what would be detrimental microstructural evolution in gallium orthophosphate (GaPO4) based on our technology. The sensor is to interrogate rotating jet turbine components and thermal protection system (TPS) tiles of space re-entry vehicles operating in a high temperature/aggressive environment for structural health diagnosis. | |

| Title: Combustion Stability Innovations for Liquid Rocket Engines | |
| Abstract: While guidelines for stable combustion in certain engine cycles and propellant combinations exist; there is no proven, mechanistic predictive model, particularly for high-performance liquid hydrocarbon-fueled engines. IN Space and Purdue propose to fill this critical need by developing a "testbed" consisting of 1) a predictive combustion stability design tool to mitigate the risk of generating instabilities in new designs or analyzing instabilities in existing designs of oxidizer-rich staged combustion (ORSC) engines and 2) a stability verification protocol to assess stability margin during full-scale engine testing. Analytical and experimental testbed elements needed to bring about these developments include subscale experiments at real-scale conditions to provide validation data; advanced CFD modeling based on detached eddy simulation, Reynolds-Averaged Navier-Stokes and linear and non-linear Euler equations to provide fundamental understanding as well as to derive and test combustion response submodels for engineering analysis; engineering state-of-the-art level design analysis for data interpretation. State of Indiana matching funds will be used to construct and test a subscale combustor experiment needed to gather stability data in Phase I. The Phase I effort provides a strong foundation for a Phase II effort, which will focus on further product improvements and validation using a test article at full-scale conditions. | |

| Title: Innovative Measurement Approaches for Harsh, Chemically Reacting Environments | |
| Abstract: In this proposal we exploit the remote sensing attributes of ultrasound to measure temperature, transient temperature and heat flux in liquid rocket combustion chambers. In previous work, we have demonstrated the capability to measure the local temperature at the inner surface of large caliber Navy guns using sensors attached to the external gun barrel surface (2.5" from the measurement point). In the proposed effort we improve the measurement methods to enable us to acquire temperature data more rapidly, modify our approach to fit the needs of the rocket combustion chamber, and enhance the analytical methods to accurately treat transients and extract heat flux from the ultrasonic data. The ability to locate sensors on the exterior surfaces of chambers removes the sensor from the chemically reactive environment and reduces the need for operation at extreme temperatures. Yet, the ability to obtain localized and instantaneous temperature data from previously inaccessible regions should enhance our ability to control and better understand liquid rocket combustion processes. | |

| Abstract: During the Phase I effort, we propose to evaluate the feasibility of performing ultrafast-laser-based ballistic imaging for studying liquid hydrocarbon and oxygen injection characteristics for possible application in bi-propellant rocket engines. Ballistic imaging has the potential to circumvent the difficulties associated with propagating light through dense media. Through the combined use of ultrafast time gating, polarization gating, and spatial filtering, photons that propagate without interference (i.e., ballistic photons) are preferentially detected over photons that undergo significant beam steering or multiple scattering. During the Phase I effort, we will (1) assemble an ultrafast-laser-based ballistic imaging system, (2) demonstrate the feasibility of using this technique for liquid oxygen and hydrocarbon injection, (3) evaluate the use of ballistic imaging using a Monte-Carlo simulation for laser-spray interaction, and (4) develop a strategy for implementation in a demonstration bi-propellant rocket engine combustion system in collaboration with the DOD and an industry partner. | |

| Title: High-current Field Emitter Arrays for Directed Energy Weapons | |
| Abstract: Field emission electron emitting arrays hold promise for use in high current density electron beam devices and can replace power consuming thermionic emitters. While single emitters can emit currents up to milliamps, large field emitter arrays are limited in total current due to non-uniformity and resulting instability problems. Solutions to these problems have been attempted using current limiting devices, including a field effect transistor (FET) for each emitter. This is a promising approach but so far has only been used for small total currents. Based on previous work ISSI in cooperation with the University of Southern California (USC) proposes to further develop both experimentally and by modeling whole arrays existing concepts and devices to meet the required total current. The work will be based on the successful demonstration of the fabrication of field effect transistor arrays combined with carbon nanotube array field emitters by USC. | |

| Title: Application of Non-Local Effects to Lasers and Plasma Chemistry in Flowing-Gas and Pulsed Electric Discharges. | |
| Abstract: Oxygen and/or air plasmas are widely used in different processes such as etching, purifying, ashing, surface cleaning, ozone generation and for electrical oxygen/iodine laser discharges. The oxygen plasma is an important example of electronegative plasmas and has been widely studied and modeled, including non-local effects due to discharge boundaries, low pressure or unsteady-state or afterglow operation. The proposed Phase I program will investigate the so far neglected effect of the relatively high energy electrons created by associative detachment of negative ions. For some conditions, these electrons can form a major portion of the electron population and causing additional non-local effects. The contribution to the electron energy distribution by the detached electrons will be investigated, and the model will include these additional non-local effects. Appropriate modeling approaches will be considered for pulsed and flowing gas plasmas. Beneficial effects or controls using the non-local effects will be investigated. In a following Phase II program, further refinements of the model will be performed and example technical plasmas will be tested experimentally. The oxygen plasma is widely used and a more accurate model and possible improvements due to better understanding of the plasma kinetics will be important for both commercial and military applications. | |

| Title: Heterodyne Correlation Random Noise Radar for Through Wall and Building Interior Imaging | |
| Abstract: Recent terrorist activities and law-enforcement situations involving hostage situations underscore the need for effective through-the-wall surveillance (TWS). Current building interior imaging systems are based on short-pulse waveforms, which are easily recognizable by the intelligent adversary who may employ countermeasures to confound detection. We propose a coherent continuous-wave ultrawideband random noise radar architecture based on heterodyne correlation and adaptive software radar techniques for covertly imaging obscured targets and interfaces. The proposed approach has the following two main advantages over competing systems: (i) random noise waveform possesses an ideal ambiguity function with separately controlled down-range and cross-range resolutions, thus providing unambiguous high resolution imaging at any distance; and (ii) random noise waveform is inherently low-probability-of-intercept (LPI), low- probability-of-detection (LPD), and anti-jam. Thus, it is an ideal candidate sensor for covert imaging of obscured regions in hostile environments. The coherency in the system can be exploited to field a fully-polarimetric system that can exploit polarization features in target recognition. Moving personnel can be detected using Doppler processing. Simulation and preliminary experimental studies not only show detection of human activity and human tracking behind walls with excellent multipath and clutter rejection, but also differences between specific activity types. | |

| Title: Exploiting Raster Maps for Imagery Analysis | |
| Abstract: The US Air Force seeks innovative technologies to exploit available map data to provide a contextual backdrop for imagery. This contextual backdrop will allow the imagery analyst to more rapidly and accurately exploit the data for further processing. Maps provide a wealth of information, such as road delineations, road names, buildings, and other cultural features which comprise the contextual backdrop for an image. In short, the desired capability should allow the analyst to rapidly "know where they are" in an image and increase their daily throughput of images without sacrificing accuracy. Accordingly, we propose to develop ContextMAX which adheres closely to the stated requirements and leverages our 20+ years of successful imagery processing development and operational transitioning. ContextMAX will incorporate novel robot-mapping techniques for performing automated map analysis, advanced tie-point extraction from imagery, and multi-source registration to create a correlated scene providing the necessary contextual backdrop to imagery analyst for a given image. By this, ContextMAX represents an innovative, low-risk solution for improved contextual awareness to the imagery analyst as well as producing modular geospatial data management and extraction techniques useful to a number of remote sensing and GIS applications. | |

| Title: Magnetodielectric Nanocomposite Films for RF Applications | |
| Abstract: Requirements for improved military communication systems operating in the GHz frequency range, such as low cost, lightweight antennas and surveillance equipment with low physical or conformal profiles, demand the development of new materials with improved electromagnetic properties. To meet this need, Luna Innovations will develop magnetodielectric nanocomposites consisting of a polymer (dielectric) matrix engineered with one or more magnetic (magneto) nanofillers. The focus of this Phase I program is to demonstrate the feasibility of a large area magnetodielectric nanocomposite film with materials properties suitable for antenna applications. To achieve this, Luna Innovations will design and prepare of unique magnetic nanofillers with tunable magnetic properties and will develop fabrication methods to prepare nanocomposite film systems incorporating these designed nanofillers into the polymer matrix. Characterization of both the filler and the magnetodielectric nanocomposite properties over a range of materials compositions and morphology will be conducted with the primary focus on the high frequency (GHz) electromagnetic properties such as the permittivity, permeability, and loss tangent. Physical attributes that lead to optimal magnetic and electromagnetic behavior will be identified and particular emphasis will be given to meeting the physical property requirements necessary to satisfy Air Force RF application requirements. | |

| Title: Self-Healing Adhesives and Composites | |
| Abstract: The replacement of metal aerospace structures with polymer matrix composites (PMCs) provides up to 50% weight savings. This reduction in weight will enable significant gains in performance (increased range, payload, and velocities) and decreased costs. One of the obstacles to the widespread use of composites is their susceptibility to mechanical and thermal damage, particularly at joints between adjacent components. These thermal or mechanical stresses result in microcracking, which ultimately leads to structural failure. Recent research has demonstrated the ability for microencapsulated monomers to self-heal a damaged composite by filling in these cracks as they are formed. While the fundamental demonstration of technique was successful, its large scale implementation has been obstructed due to cost limitations and material incompatibility leading to poor bonding. Luna Innovations proposes to advance this technology with the use of inexpensive healing materials that will form strong, tough bonds to the composites and adhesives to prevent crack propagation. Luna's team has extensive experience in the areas of microencapsulation, self healing materials, composites fabrication, and testing. | |

| Title: Language Enabled Raster Imagery Exploitation (LERIX) | |
| Abstract: Raster Maps, which represent a significant portion of our imagery assets library, have limited intelligence value in their native raster form. To unlock their value, these raster maps must undergo a complex transformation process that extracts metadata about the geo-coordinates, georegisters the scene, and extracts the texture information (features, roads, rivers) and text labels of features and locations. Text recognition is particularly challenging with respect to text segmentation (line separation), font and character code conversion, and language recognition. And with our nation at war, the text issues regarding Arabic-scripted language maps are particularly urgent. Our proposal - Language Enabled Raster Imagery Exploitation (LERIX) - offers a new approach that combines robust GIS (geospatial Information System) methods with innovative new language-aware approaches to image and document exploitation optimized for Arabic, Farsi, and English. Our GIS capabilities represent a new approach for conflation using curvilinear features, and in particular road segments and complete road networks, for the registration of maps and imagery. Our solution uses shift-, rotation-, and scale-invariant metrics to support conflation, transforming the registration problem into a spatial similarity assessment problem. And our Language capabilities provide a novel and integrated approach to text segmentation, language recognition, text extraction, and translation. | |

| Title: Electrodeless Lorentz Force Thruster for High-Power Propulsion | |
| Abstract: The Electrodeless Lorentz Force (ELF) Thruster is based on recent laboratory results on the formation and acceleration of magnetized plasmoids. The goal of the proposed research is to build and test a prototype that has the potential to surpass all current electric propulsion systems in efficiency, power, and Isp. The thrust is produced by the rapid acceleration of a compact toroidal plasmoid generated by an externally applied rotating magnetic field (RMF). The RMF directly drives an azimuthal current in the plasma, and together with the radial component of the applied magnetic field, produces a large, axial JxB force. Unlike the MPD thruster, the current is produced by the action of external antenna fields and thereby the requirement for electrodes is removed. The toroidal current is sustained by the non-inductive, steady RMF, removing the need for high-voltage pulsed power. The resultant magnetic field confines the plasmoid propellant and the external vacuum magnetic field insulates the thruster wall. The thruster can be operated with a wide range of propellants as RMF plasmas have been generated in a variety of gases from hydrogen to xenon. With a mechanism for generating a large non-thermal plasma flow, and no significant thermal loss channel, the efficiency of the ELF thruster is anticipated to be very high. | |

| Title: Adaptive Liquid Crystalline Elastomer Nanocomposites with a Unique Morphology | |
| Abstract: As part of the trend over the years of polymers replacing metals, substituting metallic wing skins with shape memory polymers (SMPs) that have excellent mechanical properties provides an opportunity to develop a new kind of morphing aircraft that can fulfil the needs of future military missions. Additionally, SMPs that can exert large recovery and regenerative stresses are needed for a broad range of space and medical device applications. Building upon work done by our STTR partner at Case Western Reserve University, we propose to develop SMP nanocomposites based on liquid crystalline elastomers to achieve reversible contractions and expansions of more than 100% upon application of a small load and heat, along with substantially higher elastic modulus in the z-direction as compared to those in the x and y directions. The key aspect of the proposed effort is in developing a novel microstructure for the nanocomposite. Nanocomposites will be synthesized and evaluated for their structural, mechanical and shape memory properties. In the Phase I program, we will demonstrate that shape memory LCE nanocomposites can exhibit high elongation-to-break ratio and high modulus in the z-direction, along with excellent shape memory properties. | |

| Abstract: The primary objective of this STTR is to develop thick, high-temperature superconducting (HTS) multi-layer heterostructures for high-power handling microwave devices and with reduced nonlinearities. Building on the resources of Neocera's materials research on HTS heterostructures and MIT Lincoln Laboratories vast knowledge on nonlinear behavior of HTS films at microwave frequencies, this STTR Phase I seeks to establish the feasibility of the proposed approach. Thick, multilayer YBCO/CeO2 film stacks, with alternating YBCO and CeO2 layers will be deposited by Pulsed Laser Deposition technique at Neocera. The films will be patterned to form stripline resonators and will be characterized for their nonlinear behavior at MIT Lincoln Laboratories. Third order intermodulation distortion measurements will be carried out as a function of power from -50 dBm to +30 dBm and temperatures from 1.8K to Tc to establish the proposed feasibility and to verify improved nonlinearities. | |

| Title: Innovative High-Power Propulsion Technologies for Orbital Transfer Vehicles | |
| Abstract: A fully integrated nuclear MHD-MPD electric propulsion system is proposed with potential to provide quantum improvement in the thrust level, specific impulse (ISP) and efficiency of MHD power system as well as the MPD thruster. The proposed MHD-MPD electric propulsion system is intended to be used as an orbital transfer vehicle for multiple uses with a single propellant tank and potential for in-orbit replacement of the spent propellant tank. Due to similarity in design, the power generated by the MHD generator could be conditioned to directly drive the MPD thruster. This would eliminate or at least significantly reduce the need for the power management and conditioning system that is a major weight and size burden for all conventional high power electric propulsion systems. The coupled MHD-MPD system could also share the high field magnet and some other auxiliary sub-systems to further reduce the overall weight, size, and complexity of the new reusable orbital transfer vehicle. The proposed MHD-MPD electric propulsion system function as a transformer with high mass flow rate and relatively low velocity on the primary (MHD) side and low mass flow rate and extremely high velocity on the secondary (MPD) side. | |

| Title: Carbon Nanotube - Quantum Dot Nanostructures for Ultra-high Efficiency Photovoltaics | |
| Abstract: Space applications continue to be limited by the availability of cost-effective power. Significantly higher efficiency cells with lower mass and volume are required to improve performance and lower mission costs; however, improvements in conventional multijunction technology are not expected to meet the necessary performance increases. Instead, new materials and mechanisms are needed to obtain the required efficiency levels. We propose a nanostructured material consisting of semiconductor quantum dots (QDs) and arrays of carbon nanotubes (CNTs) to produce photovoltaic devices with ultra-high efficiencies. QDs and CNTs exhibit critical material properties that are important to achieving ultra-high efficiency photovoltaics. By combining several sizes of QDs and different QD materials, the absorbing layer may be optimally matched to the solar spectrum. In addition, QDs increased oscillator strengths result in more efficient absorption. This allows for a thinner absorber layer and therefore the opportunity to increase the efficiency of charge collection. CNTs are the ideal material for carrier collection as they can exhibit excellent conductivity and their energy levels are well-positioned for charge transfer from the QDs to the CNTs. The proposed ultra-high efficiency devices will create significant opportunities for space-based applications by lowering mission costs while increasing available power. | |

| Title: Flex-Skins Using Cellular Cores (XSCL) | |
| Abstract: Morphing aircraft structures have been under focused development over the last five years, primarily under DARPA and Air Force sponsorship. NextGen has been a leader in this effort; prior and on-going work by the NextGen team has identified significant technology barriers which need fundamental understanding as well as innovative solutions. Key among these is the development of skins which have in-plane strain capabilities of around 100% to permit large changes in wing area, low in-plane moduli which will result in reasonable actuation force requirements, and high effective overall bending stiffness to provide efficient aerodynamic shape. To meet these requirements, NextGen and Penn State University propose to develop new morphing skin designs based on flexible cellular cores with tailor-able geometry and material properties. We will build upon the work done by Prof. Farhan Gandhi, PSU PI who has developed fundamental understanding of flexible cellular core structures. In Phase 1 the NextGen/PSU team will finalize concepts, conduct trade studies using simple models, optimize the design using high-fidelity finite element analyses, and fabricate a proof-of-concept morphing skin demonstration article. In a Phase 2 program the team will conduct detailed design addressing substructure attachment and integration within a morphing wing | |

| Title: Mechanically Adaptive Materials for Morphing Aircraft Skins | |
| Abstract: The main goal of the proposed research is to develop a material with a high modulus ratio (Ez / Ex = 105 ) by the end of Phase II. This material is ideally suited for use in morphing aircraft that require large shear strains of the skin, while limiting out-of-plane pillowing at the same time. The major effort during the beginning of the program will be to characterize Shape Memory and Electroactive Polymers to match glass transition temperatures above the operating range of the material. The two polymers will be combined and used to provide stiffness when cool and to actuate the material at elevated temperatures to allow large strains. The results of the characterization will also be used to ensure accurate material models, with further efforts going towards developing a composite model of the two materials. Phase II work will increase the modulus ratio as well as design and fabricate larger skin specimens to be tested in flight conditions. NextGen Aeronautics is a highly effective company engaged in transferring research into aerospace and munitions platform technologies. NextGen will be assisted by PSU, having done significant work with both kinds of polymers that will be used in this program. | |

| Title: Scalable Mobile Wireless Mesh Networks | |
| Abstract: The proliferation of low-cost wireless devices has led to increased commercial interest in dynamic mesh networks. At the same time, similar military requirements have surfaced, stemming from Network Centric Warfare and emerging advanced MANET applications. Tactical users stand to realize enormous benefits in size, weight, power and cost by leveraging new commercial wireless technologies, with their attractive economies of scale. However, for commercial gear to be of use to military users, fundamental differences between military requirements and commercial capabilities must be reconciled. Serious shotcomings of existing commercial systems, such as security, efficiency, and reliability over multiple network hops, must be addressed in order to transition these systems. Nova Engineering and Virginia Tech have partnered to address innovative methods for leveraging existing wireless chipsets to improve the military utility of commodity wireless hardware. We introduce unique approaches in the areas of multiple description coding, TCP/IP, networking and MAC layer improvements, and encryption. We outline all-software implementation methods for these innovations, and include demonstrations of our MD coding, MANET, and MAC research. Phase 2 will build on these demonstrations to implement a cohesive demonstration network on top of an 802.11 radio set. | |

The direct write fabrication and layer by layer methods are the elegant alternative to traditional fabrication methods of semiconductor devices such as vacuum deposition techniques, masking, high processing temperatures, etc. This project will develop an efficient, cheap, reliable method of manufacturing of novel electroluminescence arrays capable of stable, extended service, low power consumption under a wide range of environmental conditions. | |

| Title: Flapping Wing Aerodynamics and Control for Maneuverable Hovering Micro Air Vehicles | |
| Abstract: This STTR Phase I project proposes to use a Large Eddy Simulation (LES)-based computational tool to quantitatively identify the relationship between wing kinematics, flowfield behavior and aeroloads for the proposed tractor design of flapping-wing propelled Micro Air Vehicle with preliminary experimental validation. Both hovering and cruise flight modes will be considered. As a result, the feasibility of the selected LES-based computational tool for simulation of flapping-wing aerodynamics will be demonstrated. The identified relationship between wing kinematics and aeroloads can provide guidance for refining the design of the proposed flapping-wing propelled MAV in Phase II. A flight demonstration of a radio-controlled hovering tractor model will also be performed. | |

| Title: Real-Time Resource Optimization of a UAV Network for Continuous Video Tracking | |
| Abstract: Networks of UAV's equipped with video sensors promise an affordable capability to keep track of moving ground targets of military interest in an urban environment in the presence of target occlusion, clutter, and other background traffic. But maintaining continuous track on multiple targets that move in and out of the field of view of any single UAV's sensor poses a significant problem of control, coordination, and fusion of the multiple sensor resources. In addition, limited processing onboard for video tracking and limited communication bandwidth available to transmit video data to ground stations or other UAV's, make it crucial to allocate these resources in concert to achieve the maximum system benefit. Parietal Systems, Inc. (PSI) and Boston University (BU) propose to develop a unified real-time resource optimization algorithm to control sensors, processing, and communications in a distributed tracking system that fuses data from a network of UAV's in order to continuously track multiple targets in an urban environment. In Phase I we will develop and demonstrate the algorithm using analytic and simulation models of sensor, processing, and communication subsystems. We will also validate key components of the video processing and tracking model with controlled video experiments. | |

| Title: Commercial Methods for Production of Orientation Patterned GaAs | |
| Abstract: The Air Force desires development of a commercial production source for nonlinear optical (NLO) gallium arsenide semiconductor crystals with orientation patterning, i.e., OP-GaAs. The need for these materials is driven primarily by applications for NLO laser frequency converters in Infrared Counter Measures (IRCM). The proposed Phase I project will demonstrate feasibility for a fabrication method of OP-GaAs crystals that exclusively utilizes processes available from commercial vendors and at PSI. Molecular beam epitaxy, wafer bonding and hydride vapor phase epitaxy (HVPE) will be employed. Development of fabrication steps for the first two of these will be done with assistance by the University of Massachusetts, Lowell. Phase I will fabricate templates, thick films, characterize the OP-GaAs and design the commercial production flow. The proposed overall program goals for the end of Phase II are to bring on-line a new OP-GaAs production foundry based on a sequence of vendors and in-house fabrications at PSI. Production volume of QPM devices of OP-GaAs in the year following Phase II will reach 30-40 units/year. | |

| Abstract: Physical Sciences Inc. (PSI) and Purdue University (PU) propose to synthesize, characterize, and investigate the efficiency, reactivity, and selectivity of new nanocatalysts in hydrocarbon fuel liquid for RBCC applications. The nanocatalysts will have higher surface area/volume compared to conventional microcatalysts and films, thereby leading to faster reaction rates. Decreased coking will occur with use of these innovative proposed catalysts. The reaction product distribution and efficiencies of the nanocatalysts will be obtained by use of standard chromatography methods. The reaction mechanism and kinetic processes will be modeled. In the Phase II program, new nanocatalysts will be synthesized, characterized, and tested. Long-term catalytic reactivity will be optimized. | |

| Title: Development of Amorphous Alloy Coatings and the Application Technology for Aircraft Protection | |
| Abstract: This Small Business Technology Transfer Program Phase I objective is twofold. During both depot and field repair operations the coating system is removed using mechanical and chemical stripping methods that result in removal of some of the metallic cladding. The removal of the cladding during paint stripping makes the underlying high strength aluminum alloy more prone to corrosion. Thus, the first objective is to develop and evaluate new amorphous Al-based materials and demonstrate their superior corrosion resistance over other cladding materials. The enhanced corrosion resistance is the result of the amorphous state of the cladding as well as transition element and rare earth element additions. The second objective is to evaluate the thermal spray technology to meet the Air Force requirements because the application of new materials to aircrafts must be compatible with the present aircraft maintenance practice. The thermal spray technique is selected because it is highly versatile and can be easily applied at depot or in the field. | |

| Title: Combustion Stability Innovations for Liquid Rocket | |
| Abstract: Combustion instability in liquid rocket engines (LREs) has manifested in nearly all LRE development programs. While the driving mechanisms of combustion instability are vast and coupled, in all instances, the net result is significant cost and schedule over-runs. In today's business environment, such over-runs are rarely tolerated and generally result in program cancellations. Development of high fidelity computational codes to aide combustion devices design has been limited due to unavailability and excessive cost of high-powered computing platforms. With the current low-cost state of high-powered/multi-clustered computing systems, achieving the goal of modeling and simulation of coupled physical processes in combustion is realistic. | |

| Title: Environmentally-Benign Oxidizers for Propulsion | |
| Abstract: Ammonium perchlorate (AP) is the most commonly used oxidizing ingredient in solid propellant formulations. It carries a sufficient excess of oxygen to allow for the combustion of the required binder and added metal, such as aluminum. The major drawback of AP is its chlorine content which results in the formation of large amounts of HCl as a combustion product and causes severe environmental problems. It is therefore desirable to find a halogen-free replacement for AP. The goal of this proposal is the identification, synthesis and characterization of novel compounds which can provide equal amounts or an excess of oxygen compared to AP, result in similar or better performance than AP, have high densities, good thermal and hydrolytic stability, and eliminate the formation of undesirable halogen or other compounds which might be of damage to the environment or could cause ozone depletion. | |

| Title: Aided Navigation: Theory and Applications for Sensors and Architectures | |
| Abstract: The coupling of GPS and INS is often characterized as loose, tight, or ultra-tight depending on the nature of the GPS input to the navigation filter. Thus, considering the challenge of precision navigation without GPS, this project will test and validate the coupling of sensor (EO, IR) information such as ego-motion and position updates similar to the coupling of a GPS and INS system. This project draws from two technical fields: image processing and filter design. Based on our related work, image processing in context of developing robust algorithms for position and ego-motion estimation, is for the most part complete. Thus, most of the Phase I effort will focus on the filter design aspect of the problem. The primary objectives of this proposal are to (1) develop models representative of various types of coupling and (2) predict system level performance for each of these models based on measures of performance such as effective IMU drift, and navigation accuracy with and without sensor aiding. The project team is led by Scientific Systems Company Inc. (SSCI) and includes the University of South Florida (USF) as its academic partner. | |

| Title: Random Radar | |
| Abstract: We propose to establish the feasibility of using Synthetic Aperture Radar (SAR) technology to rapidly and accurately map building interiors and other structures (such as collapsed mines) interiors that cannot be analyzed with presently available equipment. When fully developed, the system would perform rapid map-making of the internals of unknown structures in a variety of applications by driving the system along side the structure. Furthermore, the system's auxiliary radar(s) or radar modes will detect and locate moving personnel within the structure of interest, and locate said movers on the structure's map. The SAR system and its auxiliary radars are small, light weight, and will be deployed on a small ground vehicle such as a small pick-up truck or other vehicle of convenience. In addition to this heretofore unavailable capability, the system will operate with very low transmitter power and use waveforms comprised of features that make the waveform appear to be random in nature. Such emissions properties provide for covert operation of the system, thus facilitating tactical advantages to military and law enforcement personnel who are attempting to defeat terrorist attacks and hostage situations. Feasibility of such a system will be established by 1) providing an electromagnetic wave propagation analysis base in models and simulations where the nature of the radar return signals from the target structure interiors through the building's walls becomes known, and 2) performing a detailed radar system design / analysis to meet the simultaneous requirements of good SAR performance and covert operations. | |

| Title: Aluminum Agglomeration and Trajectory in Solid Rocket Motors | |
| Abstract: The demand for higher performance rocket motors at a reduced cost requires continuous improvements in understanding and controlling propellant combustion. Numerous examples are available where seemingly minor modifications and improvements to existing solid rocket systems have caused previously well performing motors to exhibit unexpected and at times near catastrophic behavior. It is far cheaper to design out problems than fix them during the development or production phases. Various combustion issues have never been modeled in a complete motor prediction model. What is being proposed here has never been successfully done and would greatly increase the design tools available to the motor design community. The overall goal of this innovation is to provide a multi-physics based computer code which will accurately predict the entire flight of aluminum particles from the propellant surface through the nozzle exit plane together with a prediction of the effective properties (thermal and mechanical) of the binder, ammonium perchlorate, and aluminum particles which together constitute a solid propellant. The selection of the physics based models, not too simple and not too complex, is the key to producing a working model which will be able to run on computer systems becoming available in the next several years. | |

| Title: RF Polymer | |
| Abstract: Leveraging Spectrum Magnetics' expertise in large scale fabrication of nanomaterials together with University of Delaware's know-how in the research of magnetodielectric materials with simultaneously large permittivity and permeability, we propose to design and fabricate RF polymers that promise applications in antenna with much improved functionalities in miniaturization, impendence matching, and bandwidth. Other various applications also exist such as microwave devices, filters, and DC/DC converters which have sizable market shares. Our preliminary analysis confirmed our design concept that magnetic materials with high permeability above 1 GHz must first be developed. Guide by the physics behind high frequency materials, we choose and modify materials to achieve high magnetization, high resistivity, and low demagnetization factor. These materials will be subsequently embedded in suitable polymers to achieve RF polymers with desirable properties. Our approach will provide a commercial manufacturing technology for making RF polymers. In Phase I, we will demonstrate as obtained RF polymers with permittivity and permeability larger than 5 above 1 GHz frequency. | |

| Title: Innovative Methods to Produce Periodically Oriented Compound Semiconductor Nonlinear Optical Materials | |
| Abstract: This proposal addresses innovative, economical and safe methods to manufacture periodically oriented gallium arsenide and other III-V semiconductor materials for use in efficient quasi-phase-matched nonlinear optical devices. These crystals have the potential to revolutionize mid-IR nonlinear devices. Periodically oriented gallium arsenide allows for engineering nonlinear interactions, providing a high degree of flexibility and innovation to devices. In the infrared region, second harmonic generation of CO2 laser radiation as well as broadly tunable optical parametric oscillation in the infrared are just two examples of recent devices enabled by this technology. These devices in turn are enablers for applications such as Infrared Countermeasure (IRCM) that would greatly benefit from frequency-agile infrared sources. | |

| Title: High-Efficiency Compact Toroidal Plasma Acceleration Using Annular Helicon Pre-Ionization For High-Power, High-Specific Impulse Electric Space Propulsion | |
| Abstract: Electromagnetic propulsion using compact toroidal plasmas is ideal for high-thrust, high-Isp missions since velocities and densities are not space charge limited, the self-field structure does not suffer magnetic detachment problems and the inductive electrode-less nature has superior lifetime. This STTR builds on a long history of research by integrating an annular helicon source with a conical theta-pinch field-reversal plasma accelerator. The traditional approach using the pulsed theta coil for both ionization and acceleration has poor efficiency since a large fraction of pulse energy is wasted to plasma magnetization during the ionization phase. Preionization with DC glow discharges improve performance at the expense of lifetime. Helicon systems yield highly conductive initial plasmas (10^12-13, 3-5eV); however, the density is peaked on the centerline far away from the theta coil. This large distance results in very poor mutual inductance with the plasma secondary. The annular helicon offers a potential solution by establishing a highly-conductive plasma shell near the outer wall for superior transformer action and high pulse energy utilization for axial plasma translation. The Phase I goal of this STTR project is to evaluate the concept for Phase II moderate-power evaluation (10-20kW) through modeling and experiment leveraging strengths and capabilities at both institutions. | |

| Title: A Simulation Environment for Aerodynamic Analysis and Design of Flapping Wing Micro Air Vehicles | |
| Abstract: The work proposed here aims to develop a combined simulation and experimental capability to enhance the understanding of unsteady wing aerodynamics of flapping micro air vehicles (MAVs) and to assist in design and control of such vehicles. The overall goal is to use an advanced computational fluid dynamics (CFD) solver in conjunction with experiments for this purpose. Specifically, we aim to study the fluid physics associated with low Reynolds number flapping wings, including the fluid/structure and flight mechanism problems, to facilitate the design of effective high-bandwidth control of wing beat kinematics for MAVs. The overall proposed effort (for Phase I and Phase II) will be aimed at building a fundamental knowledge base for the physics of flapping wing Micro Air Vehicles (MAVs) including the newer "Nano" subclass called the NAVs. The proposed work will have two major components: (a) a simulation environment based on an advanced Computational Fluid Dynamics (CFD) solver, and (b) an experimental database to validate the simulations and to guide model development. | |

| Title: Instrumentation and Process Development for the Production of Orientation-Patterned GaAs (OP-GaAs) | |
| Abstract: Sunvolt Nanosystems, Inc. and Stanford University propose to develop methods to enable commercial supply of high quality, periodically oriented GaAs and other III-IV semiconductor materials. To do this, we will combine our expertise in materials research, production equipment, and process development. We will employ a soon-to-be delivered state of the art HVPE system at the Stanford University Center for Integrated Systems. The quasi-phasematching in OP-GaAs allows efficient infrared frequency conversion throughout the transparency range of GaAs from 1 mm out to 17 mm. Thus OP-GaAs is an enabling technology for compact high-power mid-IR sources for IRCM and for frequency-agile sources suitable for local and remote sensing of chemical and biological species. With near-IR solid-state laser pumping, GaAs can be tuned over the entire fingerprint region of common inorganic and organic molecules. Hydride Vapor Phase Epitaxy (HVPE) is the best available method to produce bulk OP-GaAs. There are no commercial sources for HVPE thick film growth; the best present producer is growing 0.5 mm films in small quantities with several productivity and quality issues. To extend device performance, millimeter-plus layers are required; Sunvolt Nanosystems and Stanford University will develop robust scalable processes that yield ultra-thick layers in a single growth step. | |

| Title: Reduced Nonlinearity Superconducting Thin Films for Transmit and Receive Applications | |
| Abstract: Superconductor Technologies Inc. (STI) has deployed more than 5,800 high-performance RF filter systems incorporating high-temperature superconducting (HTS) thin films. The deposition method of reactive coevaporation (RCE) used to produce these HTS films in high volume has also allowed the optimization of their RF properties to the point at which their deleterious nonlinearities have been reduced to their intrinsic limit. A new formulation of the theory of these nonlinearities for d-wave superconductors predicts that they may be further reduced by increasing the thickness of the HTS films. The RCE growth technique provides advantages in fabricating thicker single-layer and multilayer HTS films of optimal composition while maintaining excellent crystallinity. During Phase I of this project, we propose to grow such thick HTS films and measure their RF properties at STI and at Lincoln Laboratory. HTS receive filter systems with reduced nonlinearities, and hence intermodulation distortion, will benefit by being operable in high-interference environments. Increased power handling provided by reduced nonlinearity HTS films also promises to pave the way for the introduction of HTS transmit filters, thereby opening the door to myriad important commercial and Government applications. | |

| Title: Nanodielectrics for High Power Capacitors and Passive Applications | |
| Abstract: This Small Business Technology Transfer Phase I project seeks to develop and commercialize novel nanodielectrics with the internal structure enabling extremely high values of the dielectric constant. Lightweight, compact, high energy density capacitors capable of operation at several MJ per pulse and repetition rates on the order of 100 pps bursts are needed for directed energy weapons. High altitude operation places extra physical and structural demands on power components. Nanostructured dielectrics offer the opportunity to tailor the dielectric material on the nanometer scale to provide tremendous improvements in electrical, mechanical and thermal properties. The innovation is based on exploiting 1) Gor'kov-Eliashberg and 2) ferroelectric all-solid phase transition effects in dielectrics. The fabrication approach is economical and scalable. Phase I work is planned to demonstrate the feasibility of the proposed approach by fabricating and testing capacitors utilizing novel nanodielectrics. | |

| Title: Nanocatalysts for Hydrocarbon-Fueled Rocket Based Combined Cycle (RBCC) Engines | |
| Abstract: This Small Business Innovation Research Phase I project involves the development of homogeneous catalysts for cracking of hydrocarbon fuel. Future concept space vehicles employ regeneratively cooled engines which rely on the fuel to absorb engine heat to ensure survival of the engine structure at a high temperature. Using the fuel to absorb heat and burning the hot fuel efficiently keeps the heat in the cycle. For hydrocarbons, deliberate fuel cracking significantly enhances the heat sink capability of the fuel. The use of a soluble catalyst is preferred over wall-mounted catalysts because it reduces the need to develop specialized components and can be applied to a variety of platforms and configurations. The proposed catalysts - superacids- will be (1) very soluble in liquid paraffins, excluding the possibility of precipitation or aggregation and concomitant interference with the working engine; (2) highly active in catalytic cracking of hydrocarbons, including paraffins; (3) capable of thermal activation and therefore will not exhibit the corrosiveness of common superacids; (4) molecular catalysts and therefore will have all the advantageous of properties reproducibility and performance consistence; (5) inexpensive to produce in bulk and will be amenable to mass-production; (6) environmentally benign from the standpoint of ozone depletion. | |

| Title: Nanomaterial Photovoltaics | |
| Abstract: System Creations proposes to develop and manufacture radiation-hard nitride-based photovoltaics with photon to electric power conversion efficiencies of 40% or more at Atmospheric Mass 0 (AM0). The anticipated success of System Creation's approach is based on a novel nanofabrication technique, Biased-Target Deposition (BTD) and the following properties of the nitride material system: 1. Semiconductors based on nitride chemistry are direct bandgap materials that can have their bandgap tailored anywhere between 0.7 and 6.2 eV. This energy range allows efficient conversion of the entire visible solar spectrum (1.65 to 3.1 eV) and a significant portion of the ultraviolet region (3.1 to 124 eV). 2. The nitrides, due to their low density, high ionization energy, and intrinsic defect compensation, have excellent radiation-hard properties. Aluminum Nitride, which would be the outermost layer in our proposed photovoltaic device, is more resistant to the effects of radiation than Silicon Carbide. 3. A three-junction thin-film nitride cell would be capable of achieving photovoltaic conversion efficiencies of 51% (AM1.5) or more for extraterrestrial applications (AM0). Additional junctions would further increase the efficiency attainable by this material group and could be implemented without substantial increase in processing costs over the three-junction device. | |

The situation is complicated when clutter or tracks that are not of interest are in the proximity of the desired target. These situations are typical when attempting to track dismounted targets in an urban environment. Given the availability of image-based sensors (EO/IR) on unmanned aerial vehicle (UAV) platforms, a multi-target video tracking system with global track fusion and feedback can be developed to mitigate these issues. The objective of this particular research project is to develop image-based tracking algorithms for a network of UAVs that are providing surveillance of both human and vehicular targets in an urban environment. SFC has assembled a distinguished team to address this proposal. In conjunction with our university research partner, Wright State University, we are proposing a novel and innovative approach to meeting the demanding requirements listed in the solicitation. At the conclusion of Phase II, we plan to have a pre-production version of our product ready for immediate deployment in selected applications. | |

| Title: High resolution multispectral imaging with plasmon lensing | |
| Abstract: It is desirable to make high resolution imagers that simultaneously acquire multispectral information from the same spatial locations; doing so enables a number of target detection and tracking applications. Currently, image resolution is limited by the pixel pitch which cannot be reduced below optical diffraction and carrier diffusion limited values, and by the need to have different pixels respond to different wavelengths. Other approaches are either exponentially more expensive (e.g. making larger imagers), or impractical to implement (e.g. stacking pixels that respond to different wavelengths). Thus, a new technology is required wherein the pixel size can be reduced to below the limits set forth by diffusion and diffraction, and wherein each pixel can simultaneously collect information from multiple spectral bands. In this proposal, we will use the multispectral plasmon lensing to that end. During Phase I, we will demonstrate the feasibility of the proposed device with finite different time domain (FDTD) and finite difference Frequency domain (FDFD) simulations and with experimental demonstrations of the proposed multispectral plasmon lensing. | |

| Title: Soluble Catalysts to Improve Jet Fuel Combustion and Fuel Heat Sink Capacity | |
| Abstract: Rocket Based Combined Cycle (RBCC) propulsion systems likely will be used to launch next-generation space vehicles. However, in the scramjet portion of the cycle, it is difficult to maintain stable combustion because of the high air velocity and short combustor residence times. In addition, the overall heat load in a scramjet engine exceeds the cooling capacity that can be provided from the sensible heating of hydrocarbon-based jet fuels therefore the fuel must undergo endothermic cracking reactions to augment its heat sink capacity before it reaches the combustor. However, additives may significantly improve combustion and increase endothermic cracking reactions. The additive will function by reducing the activation energy of both oxidation and cracking reaction thereby increasing the rates substantially. Moreover, the products of the cracking reaction which occurs upstream of the combustor will provide additional combustion stabilization. Thus in this Phase I STTR Project TDA Research, Inc. will synthesize and test several additives that will reduce ignition delay times when injected directly into a combustor and increase the rate of cracking when mixed with the fuel upstream of the combustor. Finally, we will also obtain fundamental structural and mechanistic information on the additive using state of the art analytical equipment. | |

| Title: Mechanized Skins for Morphing Aircraft Structures | |
| Abstract: Techno-Sciences, Inc. (TSi), in collaboration with the Smart Structures Laboratory of the Alfred Gessow Rotorcraft Center at the University of Maryland (UMD), proposes to develop an innovative mechanized skin technology for large-scale area changes in morphing UAVs. The pneumatically driven morphing skin (PDMS) system will exploit superior performance characteristics of McKibben actuators, in conjunction with a new deformable and passive material, compliant matrix composite (CMC), to produce a morphing system capable of large, sustainable deformations. This proposed device efficiently marries a novel skin material with a high force and high stroke pneumatic artificial muscle (PAM) to establish a foundation for mechanized skins for morphing aircraft structures. | |

| Title: Development of Spray Coating Methods and Materials to Replace Aluminum Cladding of Aging Aircraft for Corrosion Protection | |
| Abstract: The proposed work will be directed towards developing aluminum-based crystalline and glassy/amorphous coating using thermal spray techniques (plasma and cold spray) for the corrosion protection of high-strength aluminum alloys (2024 and 7075). The coating material should be anodic to the base material for protection against galvanic corrosion. Glassy metal coatings generally exhibit superior corrosion resistance because of their structural and compositional homogeneity. While significant progress has been made recently in developing bulk metallic glasses including aluminum-based alloys, problems of depositing glassy metal coatings remain to be resolved. Plasma spray technique involves rapid cooling rates and can successfully synthesize metallic glassy coatings. Cold spray technique can also deposit amorphous or glassy aluminum coatings using precursor amorphous or glassy powder. The addition of rare earth elements to aluminum will be considered for this purpose. Optimal processing parameters of plasma spray and cold spray methods will be identified. Coatings will be characterized, and their corrosion performance will be evaluated through corrosion-potential measurements and accelerated corrosion tests in the laboratory. On the basis of Phase I results, the most promising materials and spray coating methods will be selected for more extensive trials and evaluations towards exploring their commercial potential in Phase II. | |

| Title: Image-based Tracking and Resource Allocation Algorithms for Unmanned Aerial Vehicles | |
| Abstract: We propose to develop advanced algorithms and software to collaboratively track people and vehicles in an urban environment using video imagery (visible, IR) from a network of unmanned aerial vehicles (UAVs). The tracking and data fusion architecture will have one fusion node in a surveillance region, with a number of UAVs associated with the fusion node. We propose the multiple hypotheses tracking (MHT) algorithm for each UAV local tracker, as well as the fusion node. This will provide cost effective algorithm and software development and maintenance. The local UAV tracker will process target centroid pixel locations and feature measurements extracted from its video imagery. The video processor at each UAV will perform frame registration, change detection, target segmentation, target location measurement, and target feature measurement. The pixel location measurement in the image plane is a nonlinear function of the 3D target location in the global coordinate frame. This nonlinear mapping depends on the camera location, orientation, focal length, and intrinsic camera parameters. Thus the local UAV tracker will use a nonlinear filtering algorithm such as the extended Kalman filter (EKF) or unscented Kalman filter (UKF). The UAV tracker will also process track data as feedback received from the fusion node. The fusion node will process track data received from a number of local UAV MHT trackers. We shall explore a number of track-to-track association and fusion algorithms in Phase I, and recommend the best candidate track-to-track association and fusion algorithm for Phase II. Furthermore, we will address dynamic, collaborative UAV trajectory planning and camera pointing based on the Fisher information, which is a natural choice in the context of multi-platform tracking and fusion. Proof of concept for the selected architecture and algorithms will be demonstrated using simulated and real video data. | |

| Title: Nanodielectrics Dielectrics for High Power Capacitors | |
| Abstract: Future power conditioning, control electronics and directed energy weapons will require significant energy storage for a wide range of power applications. Systems will depend on capacitors to deliver high current and high voltage under repetition. In order to find practical embodiment on mobile platforms, significant advances in compact power sources will be required. In response this need, TPL has established unique capabilities in the area of dielectrics. Revolutionary materials and processes have been identified for power sources with significant size and weight reductions. The technology is based on novel nanocomposite structures with a combination of high dielectric constant, high dielectric strength and unique mechanical and thermal properties. It is projected that the material technology will allow for capacitance power with an order of magnitude increase in energy density over current technology. The proposed program is directed at establishing the baseline performance characteristics of five uniquely different nanocomposite dielectric systems relative to Air Force applications. Detailed material characterization and theoretical material modeling will be used to support atomistic phenomenon with macro scale properties. It is anticipated that the result from the Phase I effort will establish the necessary groundwork for the fabrication prototype capacitors and pulse generators. | |

| Title: Reduced Nonlinearity Superconducting Thin Films for Transmit and Receive Applications | |
| Abstract: This STTR Phase I project is directed towards the development of high performance large-area thick YBCO films on suitable single crystal substrates through solution approach for transmit and receive applications. Two architectures of multilayer (YBCO/CeO2)xn and single layer YBCO will be explored to accomplish thick films with low surface resistance and improved intrinsic nonlinearities as measured by intermodulation distortion. A unique modified TFA-MOD approach with each coat of about 0.6-0.8Ym of YBCO and buffered with 100nm CeO2 will be used to build a sandwich structure with a total thickness of few microns. To achieve high performance thick YBCO films with improved microwave nonlinearity and power handling capability, layered growth mode is suggested and will be pursued by the control of driving force and saturation in precursor. With successful growth of high performance thick YBCO films, Stripline resonator will be built and measured. YBCO films by solution approach are cost effective and scalable technology. The proposed method is based on our previous success in making thick YBCO films. Hence, the use of solution route to make large area thick YBCO films for transmit and receive applications is a viable approach and the feasibility will be demonstrated in this Phase I research. | |

| Title: Utilizing Nonlocal Effects for Development of Novel Technologies for Plasma Chemistry and Laser Applications | |
| Abstract: UES proposes to develop and perfect a new method of controlling plasma parameters based on nonlocal nature of the electron energy distribution function in the pulsed plasmas, i.e., develop nonlocal plasma technology (NLP technology). The NLP technology is based on application of nonlocal properties of fast electrons, which have energies essentially greater than the average electron energy. Particular attention will be paid to electronegative plasma and to the role of negative ions on fast electron density. The overall tasks during the Phase I are (a) Perform theoretical analysis of volumetric processes responsible for production of fast electrons and negative ions in electronegative plasmas; (b) Complete numerical simulations of density profiles of charged particles, including fast electrons and negative ions, in oxygen and oxygen-argon mixture plasmas. Analyze fluxes of fast electrons and ions to the walls with the purpose to demonstrate the self-trapping effects; (c) Conduct initial experimental measurements of ion and electron density to benchmark the numerical simulations. The completion of the Phase I will provide validation of the NLP technology. Princeton Plasma Physics Laboratory will be a partner in this project. | |

| Title: Wavelength-Multiplexed Diode Laser Diagnostics for Harsh, Chemically Reacting Environments | |
| Abstract: Zolo Technologies and Stanford University's High Temperature GasDynamics Lab have teamed to propose the development of wavelength-multiplexed diode laser absorption measurements for a novel environment - the combustion zone of a liquid fueled rocket motor. A number of unique challenges will need to be overcome to enable these measurements. First, the pressure of the measurement zone approaches 100 atmospheres making any spectroscopic measurements difficult to quantify due to pressure broadening. Second, intense scattering of the diagnostic beam is expected from fuel droplets leading to low signal beam transmission. Third, high temperature, high pressure optical access must be engineered which is not expected to be trivial. During Phase I, we intend to show that these obstacles can be surmounted so that a system to measure temperature can be designed, built and tested during Phase II. | |

| Title: Continuous Dynamic Simulation of Nonlinear Aerodynamics/Nonlinear Structure Interaction (NANSI) for Morphing Vehicles | |
| Abstract: ZONA Technology proposes in Phase I to develop a general methodology for the assembly of nonlinear reduced order models of the multiple contracting substructures that will likely provide the morphing of future vehicles. In addition it is proposed to extend the existing 2D Gridless-Boundary-Condition Cartesian-Grid (GBCC) to 3D. Finally, these novel developments will be integrated with the existing Boundary Element Method (BEM) solver for grid interfacing between aerodynamic and structural grids. The outcome of the Phase I effort will be a prototypical Nonlinear Aerodynamic and Nonlinear Structural Interface (NANSI) solver for continuously morphing configurations. This NANSI solver will be validated on a folding wing by comparison with existing linear aerodynamic solutions in low speed regimes. | |

| Title: NAVIGATOR | |
| Abstract: 21st Century Technologies, in partnership with George Mason University, present Navigator, a system to inspect and analyze network traffic and configurations in order to prevent and detect intrusions. Navigator's graph-based representation will combine information about configuration (including vulnerabilities, topology, and trust relationships) with real-time input from sensors such as Snort and host event logs. By analyzing these combined graphs, Navigator will provide unparalleled analysis capabilities by effectively presenting both actual and potential network attacks. This will provide both the ability to execute pre-emptive hardening and rapid response to actual attacks in the context of the entire network. A key challenge in such a system is a rich and highly interactive visualization of graphs. Navigator's multi-level graph aggregation abilities will enable the analyst to drilldown and inspect data relating to a detected attack. One of Navigator's unique graph aggregation abilities is the power to reduce graphs based on common patterns - effectively hiding redundant information until it is needed. Navigator's innovative combination of powerful event correlation, attack prediction, and forensics capabilities will provide the next generation of network analysis and automated reasoning. | |

| Title: NOC - Network-on-a-Chip for Hardware-based Accelerated Simulation of Ad Hoc Mobile Communications Networks | |
| Abstract: Large scale Wireless ad hoc networks are growing in use in both military and commercial environments. In the military environment, the Future Combat Systems (FCS) initiative will rely upon the Tactical Mobile Ad Hoc Communications Network (TMACN) for all communications between warfighters, manned and unmanned military equipment, and sensors. Simulation and performance estimation of the TMACN is of utmost importance to the design and eventual deployment of this mission-critical solution. The proposed innovation is a wireless MANET simulator consisting of a semiconductor-based highly-parallel multiprocessor asynchronous Network-on-a-Chip (NoC) and an associated software architecture to enable faster-than-realtime (FTR) simulation of ad hoc networks with many thousands of nodes. By leveraging an existing NoC prototype, built in 2005 by the PI and Cornell University in a 0.18m CMOS process, and the existing software environment, we will develop an architecture design for a scalable hardware architecture and an associated software environment to simulate large TMACNs. We will then perform a detailed scalability analysis and trade-off analysis to assist in the development of a software design and low cost highly parallel multiprocessor-based single-chip hardware platform for a 90nm prototype in Phase II that will support several hundred to several thousand node TMACNs. | |

| Title: An Integrated Hardware-Software Platform for Real-Time Modeling and Simulation of TMACNs | |
| Abstract: The Army's Future Combat System will rely on a data communications backbone based on the tactical mobile ad-hoc communications network (TMACN). The unique nature of TMACNs - their mobility, adaptability, and potentially substantial sizes - makes performance prediction a difficult task, and one that is best carried out through simulation. The team of Advanced Acoustic Concepts and RTI International proposes to provide a performance prediction solution for TMACNs based on simulation through the development of an integrated hardware-software platform with two components: (1) software-based emulation for observability, reproducibility of results, and reusability and (2) hardware to accelerate run-time performance via `soft' CPUs on field programmable gate arrays for improved scalability, flexibility, and rapid reconfigurability. This simulation solution will ensure stable and effective TMACNs, which can be realistically simulated, tested, and improved more quickly, are fielded for the Warfighter. | |

| Title: Miniature Generator Power for Advanced Prostheses | |
| Abstract: The capabilities of current prostheses are substantially limited by the lack of suitable high energy density portable power. Specifically, current myoelectric prostheses utilize rechargeable batteries, which provide typically less than 10% of the daily energy required for typical activities of daily living. Such limitations in the energy source significantly limit the utility of these prostheses, and impede the motivation for addressing other shortcomings such as number of degrees of freedom and power output. Aerodyne Research, Inc. (ARI) and Vanderbilt University propose to address this need for high energy density power for prosthetic device by developing powered prostheses using ARI's miniature internal combustion engine (MICE) generator for the electric power source. A MICE-generator-powered myoelectric prosthesis could provide power for a full day of activities using a single 50 cc cartridge of butane, representing a vast improvement over current prostheses. In this proposed Phase I program, the operation of a MICE generator at the nominal power output level required for transfemoral and transhumeral prostheses will be demonstrated. Also, the power requirements for transfemoral and transhumeral prostheses will be characterized, and conceptual designs for these prostheses will be developed based on a MICE generator power source. | |

| Title: Detection of Explosive Materials Using an Encapsulated Fluorescent Bioprobe | |
| Abstract: The use of explosives over the last 100 years has left up to 16,000 military ranges contaminated with highly toxic compounds. A major challenge to the remediation of these ranges is identifying the location of persistent explosive residues. To meet this challenge, Agave BioSystems in collaboration with Universities Space Research Agency (USRA) proposes to develop an encapsulated fluorescent bioprobe for detection of explosive materials. Encapsulation of the bioprobe will rely on porous silica nanoparticles, which will provide a matrix for the probe and enhance its environmental stability by allowing chemical agents of interest to enter while leaving the bioprobe impervious to other compounds and pH fluctuations. Detection will rely on a displacement immunoassay that results in fluorescence in the presence of explosives. Dye-labeled anti-TNT antibody fragments will provide fluorescence, and antibody fragments will be attached within porous silica nanoparticles. In the absence of TNT, the TNT quencher analogue will bind to the dye-labeled antibody fragments, preventing fluorescence. When TNT is present, the TNT quencher analogue will be displaced, removing the fluorescence quenching effect. The Phase I effort will focus on encapsulating the bioprobe and detecting 2,4,6-trinitrotoluene (TNT). | |

This microfluidic optical biosensor proposed by Agave BioSystems, in collaboration with Dr. Robert Boyd of the Institute of Optics at the University of Rochester, has the potential to detect low levels of pathogens within minutes after air sampling has been completed and will not be prone to the ambiguous results associated with PCR based detection technologies. The device relies on measuring the direct absorption of biological materials on the whispering gallery mode resonators by monitoring their effect on the light resonating within its microcavity. The proposed device will respond to the specific capture of Bacillus anthracis spores by antibodies on the resonator surface. By coupling the detection mechanism to a microfluidic delivery system, the device will have the potential to be automated and rely on small sample volumes. The microfluidics will be designed and fabricated at the wafer-level using glass wafer etching to embrace the current trend in the microsystems industry. | |

| Title: Pathogen Concentration from Complex Water Supplies | |
| Abstract: ANP Technologies proposes to develop a sample concentration system that uses commercial hollow fiber filtration technology with permanent anti-fouling coatings to concentrate biological contaminants in water sources or supplies to a level high enough to be readily detected. The filter technology will allow simple and quick release of the contaminants into a much smaller volume without the use of recovery buffers, and be reusable. The concentrator can be used to monitor water supplies for a wide variety of Biological Warfare (BW) agents and non-BW water borne pathogens. | |

| Title: MEMS-Based Optical Beam Steering System for Multi-Color 2D Spot Arrays | |
| Abstract: Optically addressing a large number of atoms trapped in a periodic lattice would be a critical missing technology necessary to achieve scalable quantum computation. A micro-electromechanical systems (MEMS) based beam steering optical system is proposed to meet the needs of this topic. The system utilizes (a set of) tilting mirrors to create reconfigurable spots on a target of square lattice. The system can provide multi-color, polarization independent, nearly diffraction limited optical system without any frequency shift on the laser beams. We propose to build a Phase I prototype capable of directing the input laser beam to a 5x5 array of spots. Other research activities to demonstrate the long-term feasibility of this approach include high speed mirror development, MEMS mirrors with high power handling capability, and scalable optical design to achieve a 100x100 array of spots. | |

| Title: Low Power MEMS Retroreflectors for Optical Communications | |
| Abstract: This proposal describes a new communication device that can provide information from remote sensors through modulated retro-reflection using an active optical mirror. Through the integration of optical micro-electromechanical (MEMS) devices, high speed, low power electronics, and high precision corner cubes the project team will be able to demonstrate a modulating retro-reflector that can transmit data at 100kHz over a 1km link, while being no larger than 50cm3 and consuming no more than 50mW power. A key component of this project will be the ability to make this modulating retro-reflector for a cost of $50 in high volume. The implementation of batch foundry micromachining for the MEMS, the use of commercial off the shelf electronics, and glass molding manufacturing of the corner cube will allow this. Details of how this will be achieved are discussed in this proposal. | |

| Title: 2-D 2-Color Laser Spot Array Generation for Quantum Computing Applications:Doppler-free Acousto-Optic Multi-beam Scanners to Address and Trap Atom Arrays | |
| Abstract: We propose to develop and fabricate an optical scanner required to address a 2-D array of trapped Rubidium atomic qubits with two lasers simultaneously. One of the most scalable approaches to quantum information processing (QIP) is Optical addressing of arrays of trapped atoms. This is done with focused spots using tuned lasers which program initial states and implement 2-quibt gates. High spatial resolution of this approach will allow, simultaneously, the individual trapping of ions/atoms to be addressed and the spectral selectivity of stabilized lasers addressing these atomic transitions. The current approaches to laser beam scanning fall short of speed, efficiency, and Doppler-free operation required for QIP. We propose to design and optimize novel acousto-optic scanner system which will allow Doppler-free operation with high speed and reasonably good efficieny. In addition our novel approach to 2-color deflectors enables simultaneous multiple beam operation and is compatible with 2-D scanning to 100x100 atom arrays. The proposed multi-beam acousto-optic scanner system will be optimized for dual wavelengths at 480 nm and 780 nm, but the design architecture will have the potential to operate in a variety of visible and near-IR wavelengths. | |

| Title: High-throughput Direct Structural Screening for Drug Lead Compounds | |
| Abstract: U.S. Government personnel deployed in tropical and neotropical regions continue to be at risk for developing malaria. Drug resistant malaria parasites are becoming more common in these areas, increasing the risk of American personnel developing a serious, life-threatening disease. Cross resistance between drugs is becoming much more common. Due to the emergence of drug resistance, derivates of known anti-malarial drug classes are not long term solutions. Faced with the realities of the malaria threat, novel, unbiased technologies are required to prime the drug discovery programs. High-throughput techniques for lead compound generation are well known, but these techniques tend to be too expensive for use on tropical diseases, which do not affect rich populations. New techniques to bring down the costs are required. A method for measuring small molecules and molecule fragments will make tropical disease cures more affordable, and therefore allow the possibility of cures. This project will demonstrate the ability to of X-ray techniques to detect the interactions of cycloguanil, a known dihydrofolate reductase inhibitor, with wild-type and quadruple mutant P. falciparium DHFR-TS. This project will demonstrate automated x-ray data collection and processing to demonstrate the complete direct screening technology package. | |

| Title: High-Fidelity Modeling Tools for Bone Conduction Communication Systems | |
| Abstract: Warfighters increasingly rely on radio communication equipment to ensure safety, mission effectiveness, and situational awareness. Current military communication gear involves headphones and acoustic microphones. Unfortunately, headphones cover the ears and deteriorate detection and localization of ambient sounds that may be important for tactical situations. They also prevent ear plug usage and necessitate noise canceling headsets in high-noise environments. An alternative to air conduction is bone conduction (BC), where sound is transmitted/received through vibration transducers attached to the human head. Existing BC technology is not mature enough to provide high fidelity devices required for military operations, while their development is limited by the lack of adequate modeling and design tools. In this project we will develop, validate, and deliver anatomy and physics based modeling tools for analysis and design of cranial BC communication systems. The tools will be used to optimize the design, attachment, and anatomical location of BC speakers and microphones for best communication clarity in various military environments. CFDRC's high-fidelity Fluid-Structures-Interaction software will be used to model the filtering effects of the skull, brain, fluids, and other tissues as vibrations transit from points on the head surface to the cochlea. Resulting transfer functions will be used to predict speech intelligibility and evaluated empirically at Georgia Tech's Sonification Lab through validation studies involving human listeners. | |

| Title: A Systems Biology Approach to Enable Safe Administration of Mefloquine | |
| Abstract: The objective of this effort is to apply a systems-biology-centered methodology for the identification of subcellular mechanisms of mefloquine neurotoxicity, with the goal of developing a genetic profile to identify individuals predisposed to mefloquine neurotoxicity. The core hypothesis is that elucidating subcellular mechanisms of mefloquine neurotoxicity requires the combination of cellular level measurements and computational analysis of validated intracellular pathway models. Microarray analysis will determine the dose/response of cells exposed to mefloquine. Gene expression data combined with scientific literature, and expert guidance will be used to construct a pathway model of mefloquine neurotoxicity. The pathway model will be validated/modified using novel computational methods and gene silencing experiments. Sensitivity analysis will be performed to identify the critical pathways involved in mefloquine neurotoxicity. In Phase II, the critical pathways will be used to develop a genetic profile, including specific single nucleotide polymorphisms, capable of predicting mefloquine-induced neurotoxicity, ultimately enabling the development and commercialization of a test kit to identify individuals susceptible to mefloquine neurotoxicity. A multi-disciplinary partnership with expertise in (a) experimental measurements of cellular toxicology and (b) in silico analysis of pathway models has been assembled. This project will be leveraged off of multiple, ongoing research efforts aimed at constructing predictive intracellular pathway models to develop understanding of neurotoxic response to metal ions and organophosphorous compounds. | |

| Title: TSR-SHIELD: Time & Spatially Resolved Standoff Hyperspectral Imaging Explosives LIDAR Detector | |
| Abstract: Laser Induced Breakdown Spectroscopy (LIBS) is being successfully transitioned to field applications in both close-contact (proximity) and standoff detection modes. LIBS is attractive since it can be used to detect a wide range of chemical, biological and explosive (CBE) hazardous materials. While LIBS is well suited to evaluation of complex hazards, including improvised explosive devices (IEDs), technology approaches that will improve probability of detection (Pd) and reduce false alarm rates (FAR) are desired. Improvements in sensor performance can be accomplished by combining LIBS with Raman spectroscopy, a highly complementary spectroscopic technique, and employing state-of-the-art sensor data fusion algorithms. ChemImage Corporation (CI) teaming with the University of Central Florida proposes to combine state of the art LIBS and Raman standoff optical sensors into a leap-ahead system for hazardous materials detection. In this Phase I program, we will focus on standoff explosives detection using a novel LIBS/Raman sensor, the Time and Spatially Resolved Standoff Hyperspectral Imaging Explosives LIDAR Detector (TSR-SHIELD | |

| Title: Compact Mobile Light Filament Sensor System | |
| Abstract: Digital Fusion and The University of Alabama in Huntsville propose to develop a light filament based sensor system suitable for incorporation in an unmanned-aerial-system (UAS). This sensor system is intended to be useful, e.g., for sensing explosive residue or biotoxins at up to kilometer class distances. It has been demonstrated that white light filaments, which can propagate through the atmosphere with little divergence, are generated by sufficiently short and sufficiently intense laser pulses. This phenomenon offers a means to improve the performance of hyperspectral stand-off sensors as well as stand-off laser induced breakdown spectroscopy of materials. Potential applications are, e.g., detection at a distance of improvised explosive devices (IED) or plastic mines on the ground and of biotoxins in the atmosphere. A technology roadmap will be developed detailing means of reducing power, mass, dimensions, and cooling requirements of the required laser systems so as to transition laser capabilities for such light filament generation to UAS platforms. In parallel with this effort, we will develop a design for a UAS-based hyper-spectral sensor. This UAS-based sensor system will be developed during Phase II. We expect to seek a prototypical model having power, mass, dimensions, and cooling requirements consistent with incorporation on a UAS platform in Phase III. | |

| Title: Prediction of the Degradation of Composite Materials for Emerging Army Facilities | |
| Abstract: An innovative methodology, based on mechanistic models, will be developed for prediction of long-term (25+ years) durability of composites for the US Army's emerging facilities in different climatic zones. Accelerated testing simulating the Army's composites applications in various constructions and fields will validate it. Phase I will develop the basic predictive model using the in-house NOVA-3D computer code and will use Arrehenius principles adapted to the TTS (Time Temperature Superposition) for experiment design to measure composites degradation under simultaneous UV (Ultra Violet), stress, and hygrothermal exposure. The test will capture the synergistic effects of field exposure and extreme temperatures, viz., hot/dry, hot/wet, cold/dry, and cold/wet. The capacity loss from changes at the molecular level, such as hydrolysis, microcracks, and UV induced polymer chain-scission, will be incorporated in the model using a unique finite-element (FE) based multi-scale, multi-mechanism degradation model that was developed in-house. Phase II will refine the model to include additional chemical degradation mechanisms, relaxation and creep threshold, stress induced crack growth in fibers and fiber/matrix debond, and dynamic effects of blast and seismic events. The model will predict service life and remaining life and will be incorporated in a user-friendly Field Usable Design Tool software, to be commercialized in Phase III. | |

| Title: Colorimetric Sensors for Chemical and Biological Warfare Agents | |
| Abstract: We aim to construct litmus paper-like colorimetric sensors for detection and quantification of chemical and biological agents in water by performing combinatorial selection of DNA aptamers for cyanobacteria toxins such as microcystins and saxitoxins. Aptamers are single stranded DNA that can bind target molecules with high affinity and specificity. Such DNA aptamers are biocompatible, biodegradable, and highly stable even at elevated temperatures and dry conditions, especially when conjugated with nanoparticles. Cyanobacteria toxins are the most encountered toxins in water sources. After obtaining toxin-specific aptamers, DNA-functionalized gold nanoparticles will be used to obtain rapid, autonomous, cost-effective and easily interpretable sensors for soldiers in the field. The sensors will be made into a test strip format that can be easily used by soldiers or other users without a chemistry background. Importantly, the same technology will be applicable to detect a broad range of chemical and biological agents without an extensive support system. In the Phase I research, the feasibility of using the proposed approach will be demonstrated and prototype test kits will be constructed and characterized in Phase II. | |

| Title: Low-Cost Production of Engineered Proteins in Transgenic Plants | |
| Abstract: Plants provide an attractive platform for the production of recombinant proteins because they require significantly less capital investment than microbial fermentation systems and can be easily scaled up to produce additional protein. Edenspace proposes to develop a versatile plant expression system with tobacco to produce and purify proteins with therapeutic and industrial purposes. The gene expression cassette to be developed will include a molecular tag to simplify purification of the recombinant protein before being cleaved in order to preserve the biological activity of the protein. To demonstrate this system, Edenspace has created transgenic tobacco with its research partner at Michigan State University, Dr. Mariam Sticklen, expressing the human secretory leukocyte protease inhibitor (SLPI) protein. SLPI is well known for its anti-microbial, wound healing and anti-inflammatory activities, and through this project Edenspace will demonstrate the effectiveness of producing active SLPI in tobacco. | |

| Title: Gaseous, Liquid and Gelled Propellant Hypergolic Reaction Mechanisms | |
| Abstract: This proposed STTR Phase I program addresses elucidation of the underlying physics and chemistry associated with ignition delay in hypergolic propulsion systems. More specifically it addresses if the differences observed in ignition delay for liquid and gelled hypergolic propulsion systems are due to mainly physical and/or chemical effects. Proposed mechanisms will be developed for the gas/gas, liquid/liquid and gel/gel hypergolic reactions of mono-methyl hydrazine (MMH) and inhibited red fuming nitric acid (IRFNA) based on literature search, previous research, thermo-chemistry predictions, and engine test results. Reaction mechanisms will include both physical and chemical effects so as to enable prediction of changing ignition delays for the different hypergolic systems being considered. Following mechanism compilation, a set of test methods and apparatus will be devised that provides the best way forward in validating/invalidating the proposed mechanisms. | |

| Title: A Portable Microreactor System to Synthesize Hydrogen Peroxide | |
| Abstract: This proposed STTR Phase I program addresses design, development, fabrication and testing of a safe, convenient and economical catalytic microreactor that is capable of generating vaporous hydrogen peroxide (VHP) on demand by direct synthesis of hydrogen and oxygen that could be generated by electrolysis of water aboard a portable hydrogen peroxide generator. Phase I will consist of two major and distinct tasks carried out in parallel: 1) design, development and fabrication of a microreactor, and 2) development of a suitable catalyst for the direct synthesis reaction in the vapor phase. The catalyst developed will be properly deposited/ loaded inside the channels of the microreactor. An experimental unit will then be built to carry out the microreactor performance tests and the results will be evaluated. The operating conditions will be optimized to achieve the best hydrogen peroxide yields and throughputs possible. At the end of the Phase I program an estimate of the size and cost of a large-scale unit to be built in Phase II will be developed. The program will also identify further research or research and development needs for improvement of the new process. | |

| Title: Advanced Robotic Detection of Chemical/Biological Agents, Toxic Industrial Gases, and IEDs for Force Health Protection. | |
| Abstract: The recent rise in asymmetric warfare and terrorism has brought about an increased threat from biological and chemical weapons. Their potential lethality and their indiscriminate nature make them natural choices for use as a terror weapon. Quick, reliable, and safe detection of these agents is imperative. The Energid team proposes a novel teleoperated robotic system for the rapid detection of chemical and biological agents, including toxic gases and the chemical components of IEDs. The system, which employs an iRobot UGV PackBot platform and a novel arm for manipulation, seamlessly integrates sampling tools and assay devices. The arm will use series elastic actuators and a control system based on Energid's Actin robot control software. The system will be controlled through a JAUS compliant command, control and communication system, and will integrate chemical and bioagent detection systems by MesoSystems and Alexeter Technologies. As part of this project, we are also advancing the state-of-the-art in chemical and bioagent detection systems. We will develop an inexpensive, high enhancement factor, SERS-based spectrometer capable of quickly (<1 sec) and accurately identifying chemical and biological agents. The SERS technology will potentially provide a universal detection subsystem for chemical/bio-agents, industrial toxic gases and chemical components of IEDs. | |

| Title: Rapid Detection Nano-Sensors for Biological Warfare Agents in Buildings and HVAC Systems | |
| Abstract: Currently there is no real-time technology to detect airborne biological warfare agents (BWAs). Conventional technologies require 30 minutes to 1 hour. We propose to design, fabricate and test user-friendly, low-logistical-load biosensors capable of the real-time (~ 30 s. or less) detection and identification of airborne BWAs with high sensitivity and specificity for all classes of bioagents - bacterial spores, viruses, vegetative bacteria, and bacterial toxins - and many chemical agents. The biosensors developed will be easily used within building infrastructures, in particular HVAC systems. They will be user-friendly, have low-logistical-loads (i.e., reagents and consumables), and will allow the quantification of the density of airborne BWAs. They will allow automated remote response and the automated refreshing of antibodies and filters. They will utilize standard biofluidic techniques augmented with quantum-dot technology and optoelectronic techniques. They will incorporate two, or possibly three, different techniques for the detection and identification of BWAs: (1) the localization of antigens on grids having different pore sizes, (2) the tagging of these antigens with antibody-QD complexes and the observation of photoluminescence from the QDs bound to the localized antigens, and (3) for chemical agents and possibly small antigens, observing FRET between QDs and dies bound to the same antigen. | |

| Title: An Array of Silicon-based Direction-Sensitive Detectors for Imaging the Gamma-Ray Background | |
| Abstract: A gamma ray camera, based principally on position-sensitive silicon detectors, is proposed as a means to imaging the radioactive materials in the background. In order to maximize its utility, the background imager should be able to sense environmental alterations out to reasonable ranges, be of relatively low cost so that it can be widely deployed, and finally, it should have a large active volume so that statistical fluctuations in the count do not out-compete the environmental fluctuations of interest. In general, the qualities "low cost" and "large volume" are mutually exclusive, especially if the solid-state detectors with the best energy and spatial resolution are deployed; however, if batch-processed silicon-based detectors can be deployed, then greater detector areas can be realized, at the cost of mass attenuation and absorption probability. We will compensate for the reduced differential detection efficiency by building layers of silicon detectors, in which each individual component detector will be 3D position-sensitive, in which the interaction depth is sensed via drift time measurements, and the 2D lateral position measured via charge sharing techniques. The silicon scatter layers will be coupled with position-sensitive scintillator sensors that we are currently developing, if a high Z, high-density stopping detector is required. | |

| Title: Neurotoxicity Associated with Mefloquine, an Anti-Malarial Drug | |
| Abstract: The objective of this proposal is to demonstrate that mitochondrial oxidative phosphorylation (OXPHOS) impairment is critical to development of mefloquine neurotoxicity and to develop a test that can screen for susceptibility to mefloquine neurotoxicity. The interaction between mefloquine and the endoplasmic reticulum (ER) induces a cascade of events leading to OXPHOS dysfunction. Mefloquine disrupts neuronal calcium homeostasis via liberation of the endoplasmic reticulum (ER) store and induction of calcium influx across the plasma membrane. Mitochondrial dysfunction is mediated by a variety of mechanism including increased calcium in mitochondria derived from ER. Once ATP synthesis by oxidative phosphorylation is impaired, the cellular toxicity of mefloquine is enhanced by mechanisms discussed below. We propose to test this hypothesis and develop testing that quantitates an individual's cellular ATP generation in response to mefloquine. Given the complex nature of the neurotoxicity to mefloquine and the high frequency of adverse effects in the population, it is unlikely that a simple approach using single nucleotide polymorphisms will predict an individual's susceptibility to neurotoxicity. Establishing a physiological assay that predicts mefloquine toxicity is more practical and has a higher likelihood of success and rapid implementation. | |

| Title: Development of a Neuronal Co-Culture Bioactive Compound Sensor with Digital Stimulation and Recording Capacity | |
| Abstract: Infoscitex Corporation and the University of Massachusetts Lowell will investigate the physiology of interactions of important cortical regions by culturing murine associative and motor neurons within physically-separated culture environments in a single culture dish, connected only via axons elaborating from the associative neurons. The entire culture dish will be mounted on previously-validated electrode arrays, which will allow selective stimulation of associative neurons and recording of resultant synaptic signaling of motor neurons via a well-established digital biosensor. Communication efficiency will be compared under conditions that maximize or impede synaptic and response performance. Biomarkers for enhanced function, including neurotransmitter levels and alterations in mRNA levels will be determined. Cultures will be generated from normal mice and from mice harboring genetic alterations, also present within the human population, which diminish their cognitive performance, increase stress, and promote aggressive behavior, and for which we have been able to compensate by simple nutriceutical supplementation. Comparative studies of neural networks from these genetically-compromised mice with networks from normal mice will therefore be directly applicable for testing of therapeutic or protective interventions, and exposure to environmental insults or pathogens. | |

| Title: Microbial Detectors of Explosives | |
| Abstract: The presence of residual explosive materials in areas previously used as ranges by the US military presents a significant safety and environmental health hazard. Current methods of detecting explosives in soils require extensive soil and/or water sampling and analysis using portable laboratories. These impose significant cost and time burdens during the site remediation process. In this Phase I program, Infoscitex Corporation (IST), Texas A&M University (TAMU), and the University of Rhode Island (URI) propose the development of a new microbial detector for explosives. This detector will contain microorganisms that react specifically with targeted energetic materials (EM) and reveal their presence via intensive fluorescence. Experimental efforts will focus on development of microorganisms, production of microbial sensors, and validation on a selected energetic material. | |

| Title: Deployable Intracranial Sensor Array | |
| Abstract: Cortical Spreading Depression (CSD) as a secondary phenomenon to traumatic head injury can herald further brain tissue damage well after the initial injury. The only way to reliably record CSD is through direct electrode contact with the brain. With modern equipment this requires that the skull and dura be removed, which is only feasible in a small number of patients. Infoscitex and our partners at Children's Hospital Boston propose a novel subdural electrode array capable of being inserted through a standard hole used for intra-cranial pressure (ICP) monitoring. One of our arrays alone can cover 6 cm2 of cortical tissue, and has electrodes spaced up to 1 cm apart. The design of our array is ideal for recording the low-frequency waves of CSD. Our array will be beneficial in cases both of traumatic head injury and also brain injuries from stroke. The potential benefits to monitoring for CSD in all patients who require ICP monitoring is vast, due to the number of potential patients and the high incidence of secondary injury. The team assembled for this program involves experts in the field of subdural electrode placement and signal recording, as well as considerable experience in developing minimally invasive medical devices. | |

| Title: Development of On-Demand Non-Polar and Semi-Polar Bulk Gallium Nitride Materials for Next Generation Electronic and Optoelectronic Devices | |
| Abstract: Inlustra Technologies and the University of California, Santa Barbara propose to grow and characterize thick non-polar and semi-polar gallium nitride (GaN) wafers that will act as seeds for subsequent GaN boule growth. In this Phase I STTR effort, Inlustra will first develop non-polar and semi-polar GaN films with smooth surfaces and minimal wafer bowing and cracking. The growth conditions for each type of crystallographic plane will be primarily optimized with respect to surface morphology. Defect reduction methods will then be applied to achieve uniformly low extended defect density across the wafer. UCSB researchers will conduct extensive microstructural, optical, and electrical characterization on these non-polar and semi-polar thick films to evaluate their utility as seeds for equiaxed GaN boule growth. | |

| Title: Analysis and Visualization of Large Complex Multi-Step Cyber Attack Graphs | |
| Abstract: We propose a comprehensive and innovative approach for analysis and visualization of large, complex, multi-step cyber attack graphs. First, we select the radial space-filling hierarchy visualization module for large complex multi-step cyber attack graph due to its strengths in space efficiency and ease of interpretation. Once an attack is correlated, the attack notification service retrieves the correlated alerts that comprise the attack scenario and uses it to instantiate an attack node, binding formal parameters to arguments along the way. Second, we build our plan recognition system after a low-level alert correlation step that includes alert aggregation and alert correlation. Third, we do not require a complete ordered alert sequence for inference. We have the capability of handling partial order and unobserved activity evidence sets. Fourth, we provide advanced approaches to predict potential attacks based on observed intrusion evidence. Bayesian Network based predication can incorporate prior knowledge of attack transition patterns and handle uncertainty in the correlation process. Moreover, we apply dynamic games for graph-based attack prediction and response since the integration of attack graphs and alert correlation graphs provide "perfect" knowledge about the attacker's strategy space which is necessary to compute (Nash) equilibriums out of any mathematical game. | |

| Abstract: This work will use numerical methods to determine optimal design parameters for a compact hybrid fuel cell power system driven by a statistically determined load profile. Detailed physics-based models will be used to represent the behavior of the components in the hybrid system. The components considered in the hybrid system for Phase I will be a PEM fuel cell, Li-ion batteries and electrochemical capacitors. For the design of hybrid systems, the component models will be implemented in VTB Pro. Existing methods for bound constrained optimization will be used to design and optimize hybrid systems.

| Title: Light Filament Sensor | |
| Abstract: Optical filaments, formed by high intensity ultra-short laser pulses, provide high-intensity coherent white light in the atmosphere at great distances from the laser source. This high-intensity interrogation of the atmosphere yields backward directed emissions for detection from a sensor co-located with the laser system. This has clear advantages for remote sensing in hostile environments, or environments that require rapid deployment of remote sensing equipment, or where a single mobile platform is required. Unlike narrow bandwidth systems, the broad-spectrum generated with optical filamentation may simultaneously provide identification of many different substances with varying spectral signatures. Ionatron has extensive experience and facilities that are necessary for exploring the feasibility of filamentation-based remote sensing concepts and proposes a series of experiments to determine potential capabilities. Should the results of a Phase I effort show promise, Ionatron is uniquely positioned to integrate remote sensing capabilities in currently planned laser-guided electrical discharge products. While, Ionatron possesses world class capabilities in the atmospheric optical filamentation applications, The Denton group at the University of Arizona possesses world class capabilities and facilities related to spectral sensing applications. This collaborative effort joins two organizations with core specialties uniquely tailored for this proposal. | |

| Title: Advanced Robotic Detection of Chemical Agents, Toxic Industrial Gases, and IEDs for Force Health Protection. | |
| Abstract: We propose to develop a novel chemical agent sensor through a joint collaborative effort between IonFinity, the Jet Propulsion Laboratory, and Imaginative Technologies. This chemical sensor consists of 1) a new and powerful detector called a Differential Mobility Spectrometer which has been developed at Imaginative Technologies by team member Dr. Gary Eiceman, and 2) a novel "soft-ionization" method, based upon the micro field-soft ionizing membrane that does not fragment or multiply-ionize the sampled species which has been developed recently at JPL in collaboration with IonFinity. Our goal is to design and prototype an inexpensive, compact - 2 Kg, field portable, stand-off high-efficiency, rugged, integrated detection and identification system (TRL 6 ) for chemical warfare agents, industrial toxic gases, and chemical components of Improvised Explosive Devices in air, water and solid and integrate it with one of the emerging family of Joint Architecture for Unmanned Systems compliant unmanned ground vehicles intended for medical force health protection and combat casualty care missions.

| Abstract: KCF Technologies will develop an energy scavenging device as a component in the ankle of a lower extremity prosthetic limb. The component will be designed and demonstrated on a C-Leg, in collaboration with Otto Bock USA. The component will capture and store energy during normal activities such as walking and running. The captured energy will automatically recharge the batteries of the C-Leg. This energy will greatly extend the operational time of a battery charge, or eliminate the need for battery charge altogether. In Phase I, KCF will model, develop, fabricate and test a prototype energy harvesting ankle component in laboratory demonstrations. We will collaborate with our partners at Penn State University to model the dynamic forces at the ankle joint during walking and running, and use this information to optimize the component design and placement. In Phase II, KCF will demonstrate an energy-scavenging component in-use on an Otto Bock C-Leg. | |

| Title: Implicit Level Set Based Software for Generating Geometrically and Topologically Accurate Urban Terrain Models Using Implicit Methods | |
| Abstract: We propose a new method developed by our employees and collaborators for the digital representation of real world objects. This will result in an implicit surface urban terrain model that interpolates raw point cloud data. The method can handle complex topologies and geometries easily. Topology changes pose no difficulties. The key idea involves shrink wrapping an implicit surface around data points using the level set method. No assumptions about connectivity of these points is needed. New multiresolution techniques for speeding up the algorithm, reducing storage requirements, including information about the normals to the surface, weighting points according to their statistical significance, removing outliers, tensor voting, using dynamic visibility based interpolation, ENO interpolation and Level Set System's new, proprietary level set based compression will be developed and used here. New visual metrics involving Hausdorff distance for implicit surfaces will measure the accuracy and reliability of the resulting software package. | |

| Title: Portable High Efficiency Electrochemical Cell for Hydrogen Peroxide Production | |
| Abstract: A portable, safe, and efficient source of hydrogen peroxide that can be coupled with the Army's existing evaporation technology provides an efficient means of generating vaporous hydrogen peroxide to neutralize chemical and biological agents in enclosed areas such as buildings, aircraft, or tanks. Lynntech, Inc. has developed a patented electrochemical device which utilizes air and the electrolysis of water to generate liquid phase hydrogen peroxide. To meet the need for a high yield, efficient, portable peroxide generator, in Phase I Lynntech proposes to maximize the yield of hydrogen peroxide by (a) utilizing a modified membrane to minimize water crossover and (b) incorporating a highly efficient catalyst developed at CASE Western Reserve University. In tandem, Lynntech will optimize a vaporization process that directly couples with the electrochemical cell and to produce vapor phase peroxide. Lynntech's innovative, high efficiency electrochemical system provides a route to generate both 35 weight % liquid phase and 250-500 ppm vapor phase hydrogen peroxide and operates on water and electricity which are available in the field. The power, cost, and size of the portable hydrogen peroxide generator will be evaluated to optimize the peroxide yield and minimize the power requirements for large-scale production. | |

| Title: Software tools for optimization of hybrid fuel cell power supplies | |
| Abstract: The military's needs for soldier portable power are growing rapidly, and the only way to address this power need today is through batteries. Fuel cell power systems offer the potential of greatly reduced weight to support the soldier's power needs, but fuel cell power systems today are only poorly optimized. To enable optimization of the fuel cell power systems for given user-specified power-profiles and energy-use constraints, Mesoscopic Devices and its partner, the Colorado School of Mines, propose to develop a system-level software model to accomplish this optimization. This software tool will incorporate component and system level modeling for the fuel cell power supply and its components, as well as energy storage devices (e.g. batteries), devices to support power peaking (e.g. ultracapacitors) and power management systems. The general nature of the software will support a range of fuel cell technologies, including direct methanol, proton exchange, reformed methanol and solid oxide fuel cells. We will implement the software to provide a general framework for optimizing these systems, allowing users to enter component models for any components they wish to specify and to define the power and energy profiles required. | |

| Title: Software Tool for Composite Durability Prediction | |
| Abstract: Durability is the effect of time dependant processes, including fatigue, creep, moisture absorption, thermal-oxidation, abrasion, chemical reactions and physical ageing on mechanical properties. The ability to predict accurately the durability of composite materials and structures is critical to successfully designing for longevity. The existence of models alone is not sufficient; practical software tools must exist to employ these models reliably and efficiently in design. They must also link the multiple lengthscales at which the physical aspects of these models are based in order to provide an overall integrated tool. During the proposed research, MDC will leverage extensive composite design experience to develop a software tool for rapid durability analysis of proposed repair/upgrade/reinforcement. First, a simple graphical interface will collect information regarding the material system, cure cycle, surface onto which the composite is applied and the anticipated environmental load profile over time. Next, these characteristics will be used within several interactive models to deduce the degraded performance predicted. Finally, figures will represent key mechanical properties of the composite over time, which could use for design purposes. MIT will work with MDC during the course of this research to assist in the experimental validation and calibration of the various composite durability models. | |

| Title: Passive Object Detection System | |
| Abstract: Imaging with X-rays and gamma rays is a long established technique. It is possible with recent technological advances that standard transmission radiography may be extended to self-radiography, where the natural radioactivity of the object itself and the surrounding matrix is used as the source of X-rays. Self-radiography is much more complex than traditional radiography, chiefly because it depends on a distributed, non-quantified, and low intensity source. Mirmar Sensor builds high-pressure xenon spectrometers. These detectors provide medium resolution, highly stable, very large, room temperature spectrometers. The work proposed here leverages on the extensive detector work, nuclear search work, and soil assay work done by the team at Mirmar Sensor. Also important to this project is the additional interaction information and the flexibility of configuration provided by Mirmar Sensor's patented gridless HPXe technology. | |

| Title: Performance Map for Low-Cost Titanium Armor | |
| Abstract: The research solicited under the STTR A06-T009 is ideally matched to the core technology strengths of MSDPO - microstructure sensitive design for performance optimization. MSDPO embodies a rigorous mathematical framework for systematic design of material microstructure to meet the requirements of the designer. This methodology starts with the specification of a microstructure hull, defined as the set of all possible microstructures deemed relevant by the governing physics of the design problem. The microstructure hulls facilitate the delineation of the properties closures, depicting the complete set of all theoretically feasible combinations of anisotropic properties. It is emphasized here that it would be impossible to establish the most typical property closures desired by the designer without the specification of the microstructure hull. It is proposed to develop a comprehensive set of microstructure hulls, anisotropic property closures, and processing maps for Ti and its alloys. Armed with these datasets, the designer will be fully empowered to suitably alter the microstructures in the available stock materials and customize them for optimal (or close to optimal) performance for a given application. | |

| Title: Colorimetric Sensors for Chemical and Biological Warfare Agents | |
| Abstract: 1. Abstract. The Mirkin group at Nortwestern University has developed methods for exquisitely sensitive analyte detection that rely upon forming hybridized arrays of nucleic acid-derivatized gold nanoparticles. These methods lend themselves immediately to colorimetric detection and dipstick-style applications. The hybridized nanoparticles are (quite literally) `blue,' the separated nanoparticles are `red.' Dr. Mirkin is working closely with a company, Nanosphere Inc., on the commercial applications of these technologies. In parallel, the Ellington group at the University of Texas at Austin has developed methods for transducing analyte-binding to nucleic acid receptors into conformational or bond changes that can alter hybridization. By combining these technologies it should be possible to produce generalized, sensitive, and simple detection methods for the detection of a variety of analytes relevant to biodefense. As a proof-of-principle in Phase I, we will generate dipsticks that will change color from blue to red at low (nanomolar) concentrations of the biothreat agent ricin. In Phase II we will generalize these methods to a much wider array of chemical and biological threat agents, and will continue to partner with Nanosphere Inc. on the commercialization of these technologies. | |

| Title: High-throughput Direct Structural Screening for Drug Lead Compounds | |
| Abstract: The Army has an obvious and immediate need for greater exploration of small molecules in the search for novel anti-malarial drugs. The innovative techniques offered in this proposal utilize methods of iterated automated fragment assembly coupled with an intelligent compound screening tool to facilitate scientific advancement. The resulting computational methods can increase the rate and exploration of small molecule space for novel malaria inhibitors. The proposed Phase I research makes use of docking algorithms as prototyping methods for these computational approaches with DHFR as the target of interest. Docking methods will be expanded to include NMR research in Phase II. The Phase I research and development sets the stage for continued Phase II research and development and transition for field use. The technology's applications go beyond Army needs to all branches of the military, and also commercial and academic drug discovery pipelines. The prospect for commercialization for the resulting technology in the bioinformatics sector is high in light of the increased need for rapid small molecule search strategies. | |

| Title: Ceramic encapsulated nanoparticle-based covert taggants for tracking of materiel | |
| Abstract: We propose to develop nanoparticle-based taggants that are stable and non-toxic, and are capable of producing UV, visible and IR signatures. Combining nanoparticles with different compositions will provide the ability to produce a multitude of unique markers, each specific to a certain combination of nanoparticles. The proposed program to develop covert taggant particles builds upon recent research by our University STTR partner, who has developed core-shell structured non-toxic and highly fluorescent nanoparticles. The ceramic outer shell imparts stability to the nanoparticles against the ambient, including moisture and temperature extremes, thereby overcoming barriers associated with the use of organic dyes. The proposed effort also builds upon work done at NEI Corporation, where we have developed and commercialized processes for producing core-shell nanoparticles, along with surface modification technologies to render nanoparticles compatible with the matrix in which they are dispersed. The Phase I program will deliver to the Army sample quantities of nanoparticles with the desired fluorescent and adhesion characteristics. The emphasis of the Phase I effort will be on incorporating different chromophores within the nanoparticles, and characterizing the spectral response, along with rendering the particle ensemble adherent. A provider of covert tagging technology solutions is a partner in this effort as well, thereby providing an early path to implementing the technology in the field. | |

| Abstract: Neva Ridge Technologies and its academic partner the University of New Hampshire, introduce an innovative application of technology originally developed for gamma ray astronomy. Under this phase 1 effort we will show the feasibility of an approach that will allow for the detection of hidden objects in buildings and of voids and tunnels underground. It will rely on naturally occurring "background" gamma radiation associated with materials that compose the objects of interest. Imaging technology borrowed from the low energy gamma ray astronomy community, together with advanced signal processing techniques, will be applied in this Phase 1 effort to provide a proof of feasibility. | |

| Title: Modeling Software and Tools for Reliability Engineering of Micro/Nano-Device Systems and Components | |
| Abstract: Simulation techniques play an important role in material and device design at the nanoscale. Among these techniques, molecular dynamics (MD) simulation has become a powerful tool for revealing complex physical phenomena. However, completely modeling nano-structured materials and nano-devices of tangible size using MD simulation is unrealistic, even when using today's most powerful supercomputers. Most recently developed concurrent multiscale modeling techniques have shown promise in treating phenomena at nano and larger scales. However, these methods are still subject to some limitations. In the proposed work, we are specifically addressing these drawbacks by developing several advanced algorithms for maturization and commercialization of the Bridging Domain Method, developed by Dr. Xiao and his colleagues at the University of Iowa. At the end of the Phase I program, we will demonstrate the feasibility of seamlessly integrated multiscale and multi-physics modeling tool. | |

| Title: Nanoscale Dipole Antennas Based On Centimeter Long Carbon Nanotubes For Coupling Nanoscale Devices To Microwaves | |
| Abstract: The key challenge in coupling RF signals into and out of nanoscale devices and sensors is the development of suitable nanoscale antennas. Omega Optics proposes to collaborate with Jie Liu's group at Duke University, which has developed the first method that can grow centimeter-long, well-aligned individual single wall carbon nanotubes (SWNTs) on flat substrates suitable for device fabrication, to demonstrate the feasibility of using such long nanotubes as nanoscale antennas. It was shown that SWNTs with their length more than 2cm-long can be synthesized, which is comparable to the wavelength of microwaves. To fabricate such antenna structure, well separated and well aligned individual nanotubes will be grown by adopting a newly developed method to pattern catalyst islands with uniform size catalyst nanoparticles. The length of nanotubes can be precisely controlled by chemical etching using oxygen plasma treatment at desired locations. Dipoles will be fabricated on individual long nanotubes using photolithography method. The antennas will be characterized using HP vector network analyzer and microwave spectrum analyzer in the microwave and RF frequency range. Input impedance, antenna efficiency, radiation resistance and antenna pattern will be measured and the relation between these parameters and the structure of the nanotubes (length, diameter etc.) will be extracted from the measurements. Synthesis method that can prepare nanotubes with optimized structures for antenna applications will be developed. | |

| Title: Real Time Parallel Channel Spectrometer for 3D Cloud Profiling | |
| Abstract: OPTRA is proposing the development of a 3D cloud profiling system that combines an innovative Imaging Open Path Fourier Transform Infrared Spectrometer (I-OPFTIR) with advanced computational tomography algorithms. The proposed technology expands the capability of OP-FTIR systems to 3D profiling applications. It does this by adding a spatially dispersed array of sensors at the focal plane of a single interferometer. In this way, we maintain the high-performance of the OP-FTIR system without adding the bulk and expense of multiple systems. Moreover, the active measurement allows for detection when there would otherwise be zero contrast between the plume and background (a likely scenario for indoor test applications). System cost and weight will be further reduced by the use OPTRA's lightweight, low-cost retroreflector array. OPTRA will partner with Dr. Lori Todd of the University of North Carolina. Dr. Todd and her associates at UNC's School of Public Health have been applying infrared tomographic techniques to environmental monitoring applications for over ten years now and are the ideal partners for this STTR development The proposed system is an innovative and cost-effective means of profiling a chemical cloud in three dimensions. The proposed team represents decades of spectroscopic and tomographic experience | |

| Title: Gaseous, Liquid, and Gelled Propellant Hypergolic Reaction Mechanisms | |
| Abstract: ORBITEC proposes a parallel computational and experimental effort to understand the phenomena underlying hypergolic ignition of gelled propellants. Gelled hypergolic propellants offer many benefits to modern propulsion systems. They offer good insensitive munitions characteristics and versatile performance. However, gelled propellants typically exhibit longer ignition delays than liquid propellants. In order to realize their advantages without risking potential catastrophic failures associated with long delays, these ignition issues must be understood and overcome. The proposed program will break the complex ignition delay behavior into fundamental problems and devise laboratory and modeling experiments to address each. In each case, the experiments will assay the effect of the gellant on the particular phenomenon. The Phase I work will accomplish the majority of the modeling and will include exploratory laboratory experiments to select diagnostics appropriate for investigating each selected process. The Phase II program will conduct these experiments and measure ignition delays in a multiple impinging stream vortex injection (MISVI) thrust chamber. Via a suite of analytical techniques, the proposed work will elucidate each of the fundamental phenomena along the path to ignition, yielding an understanding of each process, the competition among them, the effect of the gellants, and the resulting regimes of ignition. | |

| Title: High-yield plant based manufacturing of bioengineered spider silk (Phytosilk) | |
| Abstract: The high strength to weight and elasticity properties of spider silk make it of significant interest for the production of advanced fibers for military and civilian applications. Plants may offer the only feasible mechanism to produce quantities of spider silk proteins sufficient to sustain large scale manufacturing of these high performance fibers. Successful implementation of bioengineered spider silks requires appropriate genetic constructs, crop plants that can be successfully transformed with the constructs, and the technology and protocols necessary to produce high yields of the expressed protein. This project proposes to bring together plants transformed with spider dragline silk constructs from the University of California-Riverside with advanced environmental control technologies and protocols developed by Orbital Technologies Corporation to provide a system capable of high yield spider silk protein production. | |

| Title: Online Treatment of Subretinal Neovascular Membranes from Laser Eye Injury | |
| Abstract: The eye is extremely sensitive to laser radiation and can be permanently damaged from direct or reflected beams. In the military environments, laser injuries may be a result of battlefield laser rangefinders, target designators, or enemy action. Individuals involved in high energy laser research or medical therapeutic lasers are also at risk from direct and reflected laser radiation. One possible result from laser irradiation is subretinal neovascular membranes on the macula, which are particularly debilitating. A procedure known as photodynamic therapy (PDT) is used to treat these abnormal membranes. Today, a system does not exist that can perform both the imaging of the retina and the treatment. One effect is that pre-surgical planning and precise application of the therapeutic laser are not optimal. The goal of this proposed project is to treat more precisely the affected area. With today's digital imaging system, especially as implemented in scanning laser ophthalmoscopes (SLOs) and with high speed image processing algorithms, we will devise a system whereby all the steps leading to the laser therapy are integrated into one diagnostic and treatment device, thereby decreasing the risk of unintended damage to the retina, unwanted visual loss, and possibly improving the outcome of the treatment. | |

| Title: SUGV-Integrated Non-Contact Deep UV Biochemical Agent Surface Detector (UVBASD) | |
| Abstract: This proposal addresses the need for miniature, low power, reagentless, robot-mounted, instruments for real-time detection and classification of trace concentrations of biological and chemical agents on surfaces. Deep UV laser induced native fluorescence (UVLINF) is the most sensitive technique for detection and rough classification of trace amounts of biological and organic materials. Photon Systems has used this technique to demonstrate detection of single spores at a working distance of 30cm. Higher levels of classification specificity can be obtained using deep UV resonance Raman spectroscopy (UVRRS), with similar levels of sensitivity to surface enhanced Raman spectroscopy (SERS), although the sensitivity is less than UVLINF. We propose an advanced, robot-mounted, electro-optical instrument that combines UVLINF and UVRRS for non-contact detection and classification of trace concentrations of biological and chemical agents while requiring no consumables or sample preparation and producing no waste products. At the heart of this instrument is a deep UV laser consuming less than 5W of battery power that simultaneously generates Raman scattering and excites native of fluorophores contained within microorganisms and many organic and inorganic materials. Using an onboard real-time algorithm the UVLINF and UVRRS data are processed to identify and classify contaminants in less than 1 second. | |

| Title: WBS Edge-Effect Dissassociation Detected by LIF | |
| Abstract: The problem of detecting hazardous trace species rapidly and sensitively is a difficult spectroscopic problem. Potentially, this problem might be solved with an elemental detection method such as LIBS combined with a molecular detection method. Laser-induced fluorescence (LIF) might be a candidate for the detection of small molecules, but for larger polyatomic molecules, the resulting fluorescence is often spread between many states and too weak for molecular detection at concentrations of interest. Simple molecules and radicals that results from high temperature combustion and plasma-interaction processes, on the other hand, are known to be readily and sensitively detected with LIF. We hypothesize that such molecular radicals will exist in the perimeter of the LIBS plasma, and can in those locations be accessed with LIF, providing orthogonal detection inside the LIBS event itself. Physical Sciences Inc. and the University of California at San Diego hereby propose to examine the potential of using LIF in the perimeter of a LIBS plasma. We will make use of the spectral information gathered during this program to develop a design for a simple LIF system that can be added to instruments like the Man-Portable (MP) LIBS system now under development by ARL and Ocean Optics Inc. | |

| Abstract: Physical Sciences Inc. proposes an innovative approach to rapidly concentrate (1000:1) bacterial spores from large volumes of water for identification. The technique is based on acoustophoresis - the separation of particles with sound. Since the technology has already been demonstrated on a small scale our primary focus is on scalability for large volumes (1000 L) in short periods of time (10 min). A primary advantage of our proposed technology is that there are no filters to replace, and after concentrating the bacterial spores can be withdrawn with a few drops of water to facilitate their analysis on biochemical spot tests. | |

| Title: Near-infrared Diffuse Optical Imaging for Noninvasive Monitoring of Cortical Spreading Depression | |
| Abstract: Cortical spreading depression (CSD) is a region of transient electrical and metabolic failure that propagates through peri-lesional brain tissue. Although characteristics of CSD have been shown to be relevant to injury outcome, subdural electrode measurements currently in use restrict monitoring only to patients requiring craniotomy. A portable, noninvasive monitoring device applicable to all patients experiencing CSD would therefore be of great clinical utility from the standpoint of furthering our basic understanding as well as guiding treatment strategies. Ultimately, the device will have broad utility across military and civilian populations for real-time monitoring of a wide variety of events ranging from penetrating brain injury to stroke and migraine. Physical Sciences, Inc. and Massachusetts General Hospital propose to develop a near-infrared spectroscopic device to monitor CSD noninvasively and with minimal interference with routine patient care. The device will produce real-time, 2-dimensional images of cerebral blood flow changes by spatial localization of the absorption coefficients of oxy- and deoxyhemoglobin. Phase I studies will determine the feasibility of the technique for monitoring CSD in a piglet model. In Phase II, a prototype device will be developed that is compact, robust, and suitable for field deployment. | |

| Title: Online Treatment of Subretinal Neovascular Membranes from Laser Eye Injury | |
| Abstract: Subretinal neovascular membranes (SRNM) are a deleterious complication of laser eye injury and retinal diseases such as age-related macular degeneration, choroiditis, and myopic retinopathy. The membranes are difficult to treat with conventional photocoagulation because they form near the fovea directly below sensitive photoreceptors. Photodynamic therapy is a promising treatment that acts by selective dye accumulation, activation by laser light, and disruption and clotting of the new leaky vessels. However, PDT surgery is currently not image-guided, nor does it proceed in an efficient or automated manner. This may contribute to the high rate of re-treatment. Physical Sciences Inc. and Boston University School of Medicine Department of Ophthalmology propose to develop an on-line, automated PDT treatment system. The system will be built around core technologies of scanning laser ophthalmoscopy and retinal tracking. The system will include fluorescein and ICG angiography as well as precise delivery of a PDT laser beam. Instrument components and software algorithms will be developed in Phase I and in Phase II the system will be built and tested in human subject trials on patients with SRNM. After the Phase II program, the system will be delivered to the U.S. Army Medical Research Detachment at Brooks City Base TX. | |

| Title: Gaseous, Liquid, and Gelled Propellant Hypergolic Reaction Mechanisms | |
| Abstract: Contemporary storable hypergolic bipropellants such as MMH and IRFNA are desirable for use in military rocket applications due to their high specific impulse, no separate ignition system, and to actively control engine thrust. There is also great interest in safer munitions using gelled and lower-toxicity propellants. Unfortunately, the computational tools needed to accurately predict performance with these propellants do not yet exist, costing a great deal of time and money in testing and redesigning under-performing hardware. A validated, modular, multi-phase, chemically reacting Computational Fluid Dynamics (CFD) code capable of accurately simulating gelled propellant ignition and combustion could therefore substantially decrease the cost of developing new IM-compliant weapons systems. We propose to develop such a code employing new reaction chemistry mechanism reduction techniques, non-Newtonian gel atomization, and spray vaporization and solid-particle combustion sub-models incorporated into an existing multi-phase reacting flow CFD code. Success in this effort will allow us to characterize engine performance with gelled propellants and accurately predict ignition delays in engine hardware, decreasing the risk of energetic disassemblies during development. The understanding gained could also help design a relatively simple bench-scale test for gel propellants instead of using full-scale engine hardware, making the screening of lower-toxicity and alternative propellants much more efficient. | |

| Abstract: It is the purpose of this Phase I STTR program to both demonstrate proof of concept of long nanotubes as receiving and transmitting microwave antennas, and to develop detailed simulation tools to predict their performance and determine the optimum geometry. This will build on four years of UC Irvine experience fabricating mm long individual single walled carbon nanotubes, and pioneering theoretical work by the two groups that have simulated nanotube antennas from an RF engineering point of view. If successful, this will lead to work on developing techniques to economically fabricate optimized antennas, including arrays. The work plan will involve close coordination of all participating institutions. RF Nano work will proceed according to standard processes it is currently developing. UC Irvine work will involve laboratory measurements of antenna performance. UWM work will involve simulation for the control experiments and possibly new electrode or nanotube antenna designs. The work will be divided into 4 tasks: Task 1: Manufacture prototype ultralong nanotube antennas (RF Nano Corporation Lead) Task 2: Demonstrate nanotube antenna (UCI lead) Task 3: Demonstrate wireless bio-sensor and RFID proof of concept (UCI lead) Task 4: Simulate effects of substrate, feed electrodes (UWM lead) | |

| Title: Protein Production in Tobacco from an Amplified Inducible System | |
| Abstract: This Phase I proposal will test a UV-B light inducible system in tobacco to produce exceptionally large amounts of protein. There are three principal components to the system: 1) a tightly regulated, UV-B inducible promoter fused to a geminivirus replication associated protein (Rep) coding region, 2) a geminivirus-derived vector that is rapidly amplified by the Rep protein to produce very high yields of the target protein, and 3) plant growth under light-emitting diode (LED) lighting for precise control of the expression system. After sufficient plant biomass accumulation, exposure to UV-B will trigger production of Rep. The Gemini vector DNA will then be precisely excised from the plant genome and replicated episomally, leading to very high intracellular concentrations of transgene mRNA and the encoded transgenic protein product. The specific aims of the Phase I proposal are to: 1 Assemble UV-B inducible genetic constructs to express Rep protein and introduce them into tobacco plants. 2 Test a prototype LED-based lighting system for plant biomass production. 3 Test background expression levels and upon UV-B activation, test the ability of the constructs to induce the geminivirus based expression system in tobacco. 4 Determine the total amount of protein produced per gram of plant biomass. | |

| Title: Low Power Retroreflectors for Optical Communications | |
| Abstract: Optical retro-reflectors have been used for communications for many years. The approach has many advantages, when one terminal has limited power, space, weight, and a low cost as requirements. The major limitation for "Retro-Comms" has been that the modulator consumes too much power at higher modulation rates. What we propose is to reduce the power, size, weight and cost of the Retro-Modulator (RM) by improving the design of a deformable mirror, and its drive electronics. The RM device is largely capacitive, and the drive electronics and the modulation approach can be optimized so that the energy is recycled and dissipation is minimized. Further, we propose to use a co-located Photo-Voltaic converter to convert a part of the incident light to power the RM driver, and electronics. A further aspect of our design is that it can be deployed as a projectile. During Phase I we will design the circuitry, and test existing RM devices, capable of 100 kHz modulation, to improve the basis for designing higher performance devices. In Phase II, we will demonstrate the new design, and show modulation of beams at ~1500 kHz, with high beam quality retro-reflections. In Phase III we will do a full system demonstration. | |

| Title: Development of On-Demand Non-Polar and Semi-Polar Bulk Gallium Nitride Materials for Next Generation Electronic and Optoelectronic Devices | |
| Abstract: GaN-based electronic and optoelectronic devices have demonstrated superior properties for applications involving visible and ultraviolet light emitting diodes (LEDs), laser diodes, and high-power electronic devices. Despite the significant improvement in the performance of these devices, they still suffer from strong built-in electrostatic field due to spontaneous and piezoelectric polarizations, and high defect density and biaxial strain due to the heteroepitaxial growth on foreign substrates, both being undesirable in the operation of devices. In response, Sensor Electronic Technology, Inc. has defined a novel approach for producing free-standing low-defect density non-polar a-plane GaN substrates suitable for the growth of the next generation of devices. Thick a-plane GaN boules will be grown by a combination of growth processes, including selective area lateral epitaxy (SALE) and HVPE, which will lead to defect densities below 107 cm-2. SALE will provide low-defect smooth templates for subsequent thick boule growth by modified HVPE. SALE templates will help in preventing cracking and bowing of the wafers. | |

| Title: A powered foot and ankle prosthesis for improved maneuverability and reduced metabolic cost | |
| Abstract: This Phase I STTR proposal seeks to address the need for development and implementation of novel powered prosthetic foot-ankle components that can by used by military personnel with lower-limb loss in typical military and civilian environments. A cost-effective, biomemetic, dynamic foot-ankle system is proposed that improves balance, walking speed, gait metabolism, and prosthesis control compared to current passive foot-ankle technologies. Additionally, the system will be developed for use by military and civilian personnel in situations that include stair ascent and descent and uneven terrains. We propose to develop a prototype of an active ankle-foot prosthesis comprising motor, spring and variable-damping elements. These electromechanical components and power components will meet practical size, weight and energy requirements. With this prosthesis, both ankle joint impedance and mechanical power generation will be controlled, offering the civilian and military below-knee amputee improvements in walking metabolism and gait pattern. The muscle like-actuation and biomimetic control will be validated for stair and slop ascent, descent, and uneven terrain.

| Title: Modeling Software and Tools for Reliability Engineering of Micro/Nano-Device Systems and Components | |
| Abstract: The ability to develop new generations of superior military systems and civilian products requires the use of multifunctional materials and ever smaller components for which key design parameters are associated with nano-scale constituents. The ability to understand and design these materials and components requires the application of multiscale simulation technologies that can account for interactions across many decades of spatial and temporal scales starting from the atomic scale. The goal of this project is to build on the research efforts on multiscale modeling of the past decade to develop a set of integrated computational methods and associated software components that seamlessly couples and spans multiple spatial and temporal scales needed in the simulation of systems that are subject to thermal and shock loading. To meet this goal the areas to be considered include (i) determination of the models and scale linking functions required for non-equilibrium problems subject to a combination of high speed thermal and mechanical loads, (ii) the adaptive methods needed to ensure reliability of multiscale analysis, (iii) methods to execute the massive computations required on parallel computers and (iv) verification and demonstration of the methods developed on problems of interest to the Army. | |

| Title: Light Filament Sensor | |
| Abstract: When high powered laser pulses are focused in air, light filaments with extremely long propagation distances and high intensities can form. In this STTR Phase I project, we will investigate the potential of laser light filaments for sensing applications. Direct comparisons will be made between ultra-violet and near-infrared filaments and an assessment of suitability these filaments for standoff or remote sensing will be made. Phase I will demonstrate the feasibility of light filament sensing. In Phase II a prototype instrument based on light filaments will be constructed and tested. | |

| Title: Development of a Neural Co-Culture Bioactive Compound Sensor | |
| Abstract: Synkera Technologies proposes to develop a bipartite Living Neural Networks (LNN) platform capable of sustaining two different types of intercommunicating neuronal modules that can be independently exposed to and record electrical and biochemical perturbations. The focal point of the proposed sensor will be a micromachined biochip platform for guided and reproducible growth of LNN on ceramic substrates. The advantages of this platform include the following: (1) improved growth characteristics of the neural co-culture, (2) the ability to reproducibly control neuronal and axonal outgrowth between two LNN, (3) the ability to provide discrete access of biochemical perturbations to each LNN, (4) the ability to provide nanoelectrode access with superior electrical characteristics and contact to the LNN, and (5) fewer processing steps for less expensive devices. | |

| Title: Ranging and Acuity Enhancement for Terahertz Imaging Spectrometers | |
| Abstract: This Phase I effort identifies and analyzes a variety of antennas that can be used to mitigate standing-wave effects for pulsed and/or CW sub-millimeter-wave and THz imaging spectrometers independent of their technology (e.g. mm-wave vector network analyzers vs. fast-pulse time-domain THz systems). A close collaboration with Prof. Susan Hagness, who is an expert in computational electromagnetics at the University of Wisconsin-Madison, ensures that the antenna designs we propose will be both simulated and optimized computationally to reduce effort in fabrication and testing, which will be the focus of a Phase II effort. This Phase I effort will establish the initial antenna designs, plans and preliminary measurements required to substantiate a demonstration plan in the future and to make predictions for range and acuity enhancements, while the Phase II effort will result in a prototype system capable of mitigating standing wave effects in THz-frequency spectral imaging applications of interest to the U.S. Army and DoD. | |

| Title: Recombinant and Engineered Protein Accumulation System (REPAS) | |
| Abstract: To fully realize the benefits of genetically engineered proteins, manufacturing costs and development time must be significantly reduced. Technologies that combine robust expression, and inexpensive methods of purification are key to this goal. This Phase I proposal will demonstrate the feasibility of Tetrahymena thermophila, a common pondwater ciliate, as a novel system for low cost production of recombinant proteins using strategies that focus on a "model" vaccine antigen with considerable importance in human and animal health, namely, the hemagglutinin protein (HA) of influenza virus. Our specific goals are to 1) introduce the HA gene from the current H5N1 strain of avian flu into T. thermophilia 2) screen recombinant cell lines for the expression of HA using antibodies specific for the protein; and 3) devise rapid, inexpensive methods for downstream purification of candidate vaccine antigens. | |

| Title: Multifunctional Nanoparticles for Tracking of Materiel | |
| Abstract: The ability to tag and track equipment and other supplies is an important logistical need for military operations. To address the need for covert material taggants, a non-toxic, highly stable nanocrystal quantum dot (NQD) based taggant with covert chromophoric spectral emission signatures will be developed. Based on our experience and ongoing research, strong candidates for initial particle composition and size have been identified and the baseline chromophore/NQD coupling chemistry results in a taggant technology that is both distinct from and superior to contemporary solutions, in terms of the number of unique taggants, the distinguishability of tags, and their long term environmental stability. It is also non-toxic, and therefore adheres to the increasing worldwide regulations against toxic materials. During Phase I, a series of taggants will be synthesized and the taggants ability to be easily applied to a variety material, including fabric, by simple methods, such as aerosol spray will be demonstrated. The NQD-chromophor taggant, as well as the delivery technology will then be optimized for both response function and environmental stability. Our strong expertise in functional nanoparticle synthesis, ink chemistry, and optoelectronic systems gives us great confidence that our proposed solution will meet the Army's application requirements. | |

| Title: Modeling Software and Tools for Reliability Engineering of Micro/Nano-Device Systems and Components | |
| Abstract: Weidlinger Associates Inc and Cornell University propose to create a Computational Environment for Simulation of Micro/Nano-Devices (NanoSE). We will develop a fully integrated software tool that will enable army researchers and design engineers to simulate the behavior of devices, such as multi-function sensors, with extreme thermal and mechanical loading typical of battlefield conditions. The resulting tool will allow for seamless incorporation of physical effects on multiple length and time scales in one integrated simulation. Mathematically consistent and numerically stable algorithms will be evaluated to achieve full coupling of a flexible, modern and powerful molecular dynamics code with a proven, industrial strength, explicit finite-element wave propagation simulation package. We will evaluate an option to couple the explicit finite-element code to a high-order adaptive hp-version finite element code to incorporate macroscopic behavior on a even larger length scale. Key to the efficiency of our integrated multiscale modeling package is the utilization of an adaptive software, adaptive modeling, adaptive discretization (A-SMD) approach. | |

| Title: Confinement of Threading Dislocations at the CdTe/Si Interface for Improved HgCdTe IR Sensors | |
| Abstract: Stringent requirements on the performance of third generation HgCdTe infrared detectors demand the availability of affordable high quality substrates with very large areas. The large areas are needed both for the fabrication of single very large focal plane arrays (FPAs) (2048x2048) and to increase the yield of smaller size FBAs per wafer. The quality of commercial CdTe/Si technology, the best large-area composite substrate available for the epitaxial growth HgCdTe, has reached a plateau such that significant improvements using current growth techniques are doubtful. However, the growth of CdTe on Si/Si (and potentially on Ge/Si) twist-bonded substrates (TBS) promises to transform this technology to markedly higher quality levels. We propose the epitaxial growth of CdTe on Si/Si substrates by Molecular Beam Epitaxy (MBE) as a promising method to prepare CdTe layers. Such layers will have significantly reduced threading dislocation density at the CdTe surface than what is available today. The CdTe/Si substrates will then be used as composite substrates for the growth of large area HgCdTe epilayers. We further propose to identify the requirements and design a high vacuum wafer bonding system for the fabrication of Si/Si and Ge/Si twist bonding structures. | |

| Title: Orthogonal Spectroscopic Technologies for the Detection of Hazardous Substances | |
| Abstract: Reliable, high-sensitivity detection and identification of hazardous substances at stand-off distances is beyond the reach current commercial solutions, such as laser induced breakdown spectroscopy. To improve the possibility of detection and lower false alarm rates, spectroscopic techniques orthogonal to conventional LIBS systems are required. We propose to combine femtosecond LIBS with a radical new air-based THz generation and detection technique to create an orthogonal spectroscopic system with unparalleled capabilities to detect and identify hazardous materials in field conditions. Nonlinear optical mixing in ambient air using a portable Ti:sapphire laser generates unprecedented intense and ultrabroad bandwidth THz pulses, exceeding the performance of current solid state materials. Heterodyne detection of pulsed THz waves by using the ambient air has also been demonstrated, and holds the potential to be the most sensitive detection method yet. This revolutionary technique can be applied anywhere there is air, even at distances considered impossible using conventional methods. The proposed project will integrate a commercial femtosecond LIBS with a THz-ABCD system, and prove the feasibility of using the two techniques together to improve detection reliability. A prototype with stand-off capability will be demonstrated in Phase II to detect explosive compounds in an site survey security context. | |

| Title: SCALE: Spontaneous Collaboration Assistant and Linking Engine | |
| Abstract: Static organization charts and standard processes define roles, methods, and authority in useful ways for common missions. But these same, rigid structures force the organization to behave inefficiently, often ineffectively on problems in new domains, problems requiring new coordination methods and ad hoc teams. What is needed to facilitate rapid formation of effective human networks is a system that non-invasively monitors the rich content of digital media and conversation, builds knowledge of ad hoc and potential networks, and accurately recommends new opportunities for collaboration. The proposed research addresses this need by developing the Spontaneous Collaboration Assistant and Linking Engine (SCALE), an innovative new technology that integrates three cutting-edge approaches: . Text mining of digital documents and communications to construct an organizational model of members' areas of knowledge/work and existing collaboration relationships; . Reality mining of physical interactions between people to augment the model of organizational knowledge and collaboration; . Social network analysis to identify new productivity-enhancing opportunities for spontaneous collaboration between members of the organization. | |

| Abstract: Cornerstone Research Group Inc. (CRG) and the University of Colorado at Boulder (CU-Boulder) will establish the fundamental understanding of materials and mechanical interaction necessary to develop modeling capabilities and fabrication processes for fastening morphing skins. During Phase I, CRG will conduct a broad array of multidisciplinary research ranging from biological systems to emerging mechanical design methodology related to fastening. Phase I efforts will focus on demonstrating the feasibility of overcoming existing fastening challenges at boundary conditions as well as demonstrating predictive modeling capabilities. CU-Boulder will develop and validate a constitutive continuum model for use in finite element analysis (FEA) of morphing materials. Phase II will optimize and extend the fastening methodology and modeling capability to tackle more complex fastening situations beyond simple perimeter boundary conditions. The establishment of the proposed advanced fastening methodology will provide significant enhancements over existing morphing materials performance enabling orders of magnitude increase in lifecycle performance, cost, aerodynamic performance, and signature control. | |

| Title: Light-Activated Shape Memory Composite | |
| Abstract: Cornerstone Research Group, Inc. (CRG) and the University of Pittsburgh (Pitt) will develop light-activated composite materials technology. This development effort will enable the next generation of military vehicles to quickly and efficiently undergo dramatic reconfigurations as necessary to respond optimally to unpredictable warfare scenarios. Light-activated composite materials technology will provide significant enhancements over existing morphing materials approaches enabling higher performance capability for future morphing vehicle systems. The advanced functionality of these materials will include faster activation times, lower energy consumption, and bi-stable state performance. The primary light-activated material sought under this effort is light-activated shape memory polymer (LASMP). When applied as a direct replacement for thermally-activated shape memory polymers, LASMP will significantly reduce the time required for reconfiguration, reduce the overall energy consumption to switch and hold, and increase mechanical performance during shape change by allowing rapid on-off (digital) modulus switching at only discrete locations otherwise. | |

| Abstract: Ecliptic Enterprises Corporation (Pasadena, CA) and California State Polytechnic University (San Luis Obispo, CA) will conduct exploratory and advanced development of a family of concepts enabling cost-effective, recurring opportunities for launching very small (<20 kg) `microsat' to `nanosat' to `picosat' secondary payloads on existing and emerging U.S. launch vehicles and spacecraft while also allowing for deployment and capable proximity operations of such systems around their host platforms once in space. The proposed effort starts with elements of the proven "P-POD" launch system for CubeSat-class (10 cm x 10 cm x 10 cm; ~2 kg) space systems overseen at Cal Poly and elements of the novel RocketPodT CubeSat-class launch system invented (and now patented) by Ecliptic. RocketPod is derived from Ecliptic's very successful RocketCamT family of onboard video and imaging systems for use with rockets and spacecraft. We start with these concepts, refine them, and also scale up a bit, like "P-POD and RocketPod on steroids." | |

| Abstract: We propose to design and implement a domain-specific language (DSL) called Nettle that will eliminate a large class of network misconfiguration errors, together with a verification tool that will be used to establish the correctness of other network configuration specifications. Advantages of our approach include: - It can be deployed gracefully and incrementally. The use of Nettle will guarantee many local behavioral properties, as well as certain more global ones, and as more organizations use the framework, greater degrees of correcness can be ensured. - Nettle will be expressive. We will not excessively limit the range of routing decisions that can be expressed. - Nettle will be efficient and platform independent. It will be possible to compile programs written in the DSL on a variety of router platforms and configurations. | |

| Title: Scalable Information Assurance Through Thermodynamical Traffic Analysis | |
| Abstract: The objective of this joint proposal between Hotspot Dynamics and the Naval Postgraduate School (NPS) is to design and evaluate a large-network deployable computer network defense (CND) system based on thermodynamical traffic analysis (TTA). The system has linear scalability with increased network size (number of hosts and traffic level) that is superior to the exponential scalability of conventional approaches (signature- and heuristic-based) that will not be applicable to future network sizes. In addition to improved performance, TTA also represents the only known scientific approach for describing computer networks with the potential to provide significant improvements in false alarm rates for larger scale networks. It is applicable to the detection of novel ("0-day") attacks, covert channels, encryption-based techniques, and the increased traffic diversity anticipated in future large-scale networks. The Phase I effort will result in a clearly articulated architecture capable of faithfully taking TTA into the mainstream. By allowing the now fully-developed underlying principles to be incorporated into a carefully planned architecture, the foundation will be laid for freeing CND from its present reliance on ad hoc methods. In short, the Phase I work will provide a blueprint for the subsequent development of a production system beginning in Phase II. | |

| Title: Safe, Backpackable Method For Field Neutralization of Small Arms | |
| Abstract: This Phase I STTR effort involves harnessing the power of accelerated corrosion for the purpose of safely neutralizing small arms caches. A key part of the fight against irregular forces is finding their hidden small arms caches and either removing or destroying them. When removal is not possible or practical, destruction in place is the alternative. During Phase I, Lynntech, in collaboration with Professor Florian Mansfeld at the University of Southern California, proposes to develop a safe, non-toxic powdered formulation to rapidly neutralize small arms discovered by our combatants in place. This formulation will be packaged into sealed pouches which can be easily opened and the contents dispersed over the weapons to rapidly corrode them and damage them beyond use. Absorbing water even from dry air, our powdered formulation will render small arms non-operational within a few minutes and completely non-salvageable within a few hours of contact. We will develop the necessary packaging to enhance the shelf life and usability of the formulation. During Phase II, Lynntech will optimize the formulation and team up with chemical manufacturers and packaging companies to enable commercialization for mass procurement by our armed forces in the future. | |

| Title: Responsive Secondary Payload Launch | |
| Abstract: This effort will develop the power, communication and launch vehicle (LV) interface systems of a parasitic "drone" satellite to be used in close proximity with a host satellite. The power system will harvest energy from the side lobes of the host satellite's microwave transmissions. The communication system will transfer data with the host through that same microwave frequency, negating the need for a second communication system on the host spacecraft. The launch vehicle interface will be a responsive and non-intrusive separation system that requires no electrical connections with the LV and bonds on to the structure late in the integration cycle. The interface accommodates both controlled separation as well as redocking maneuvers; it also has the capability to transfer power to the drone if the choice is made to run power lines to it. The interface can bonded to either the LV or the host spacecraft as the individual mission requires. | |

| Title: Rosetta Phone | |
| Abstract: Most DoD missions occur in areas of the world where the native language is not English. The warfighters find themselves in situations where a quick, real-time translation of signs, placards, and documents could lead them out of dangerous situations or provide important clues and information relative to the mission at hand. In places such as Afghanistan or North Korea, this turns out to be a particularly difficult problem, since the languages commonly used in these countries are written with characters that cannot be typed into a translation device or even searched for in a dictionary (unless the user has a significant knowledge of the given language.) A valuable tool would be a handheld device (e.g., a mobile telephone or PDA) that would be capable of translating the text found in natural scenes into spoken English and text. The device should also possess the ability to transmit the captured image and text information to other warfighters in the area or to the warfighter's command and control organization or intelligence agencies that may assist in understanding the image as it applies to the larger overall mission. The Rosetta Phone takes the form of a handheld mobile device (HMD) such as a mobile telephone or a PDA. The HMD is assumed to be equipped with a color camera and, at least part of the time, wireless network capabilities. In order to be able to provide a translation of text found in natural images, the HMD needs to be programmed to perform the following sequence of tasks: . Natural Scene Image Acquisition . Text Segmentation (TS) . Optical Character Recognition (OCR) . Text Translation (TT) . Audio Output Once these tasks have been performed, several output items are available for display/listening, including the original image, the segmented text image, the optical character text, the English text translation, and the audio file (MP3) of the translation. The user will be able to choose to transmit any of these to a server, or to other users' HMDs supporting the mission. Each of the five tasks needs to be accomplished by the HMD in real-time and autonomously to ensure operation without the help of a remote server. | |

| Title: Fiber Reinforced Shape Changing Polymer Composites | |
| Abstract: With the recent development of structures that enable morphing aircraft, there is a need for a skin material capable of high in-plane strains while resisting aerodynamic loads. NextGen Aeronautics has partnered with the University of Pittsburgh to develop a fiber reinforced shape memory (SMP) matrix composite material for morphing wing skins. By pairing a fiber with an SMP matrix a composite is created that will withstand high out-of-plane surface pressures yet once activated the SMP will facilitate actuation with low external energy requirements. NextGen Aeronautics will combine its knowledge from the development of FlexSkin, a skin capable of large in-plane shearing, with University of Pittsburgh expertise in the area of developing smart and morphing materials. The objective of the Phase I research is to demonstrate a fiber reinforced composite with an SMP matrix that is capable of 60 degrees in-plane shearing. The ability to undergo large shearing shape changes and the out-of-plane stiffness will be demonstrated experimentally. Phase II will focus on improving the activation mechanism of the SMP and the response time of the shape change. The team will demonstrate the integration of the skin onto large morphing aircraft structures. | |

| Title: Built-In Filament Control for Long Lifetime in Broad Area Diode Lasers | |
| Abstract: The elimination or suppression of filaments through the use of photonic crystal structures is proposed in this STTR. Filament formation is a well-known problem in high-power, broad area semiconductor diode lasers, often leading to catastrophic failure of the diodes. The diode failure also normally results in a system failure in the systems in which the diodes are employed. By using a bi-directional periodic structure, milled into the laser using a Focused Ion Beam, it is shown that mode control can be exercised over the optical mode of the high-power, broad area diode laser. Mode control serves to eliminate or suppress filament formation in the diode laser, thereby eliminating or suppressing this pernicious failure mode. | |

| Title: Rapid Formation of Virtual Organizations Using Modeling and Multi Agent System Technology | |
| Abstract: Perceptronics Solutions, Inc. and the USC Computer Science Department present this proposal to develop an adaptive software system that will automatically form 'virtual' human networks. Our objective is to develop an automated system capable of: (1) identifying groups of people who should be in contact with each other by virtue of their parent organization's basic mission, that is, the long term problems it intends to solve; (2) organizing ad hoc groups of people to solve a specific problem encountered by the organization, taking into account organizational structures and individuals' positions in that structure; or (3) identifying new areas of organizational capability, or problem solving ability, based on the observed interests of the organization's members. Specifically, we will focus our Phase I efforts on automatically forming a problem-oriented virtual network in a dynamic military organization. The advantage of this approach is: (1) it directly addresses the military application, which has top priority; and (2) the solution will hold for less demanding applications as well, such as more static military and non-military organizations including civil agencies, companies, universities, and so forth. | |

| Title: INTELLIGENT DRIVERS USING OPTICAL SENSING | |
| Abstract: Science Research Laboratory (SRL) and the Penn State Electro-Optics Center (PSU) propose to develop intelligent laser diode driver technology, incorporating optical diagnostics, that extends the operating lifetime of laser diode arrays by an order of magnitude. Random perturbations of temperature or current density during operation of a laser diode array can lead to thermal runaway and the formation of current filaments; the high local temperature, current, and optical power associated with these filaments damages the emitters and eventually leads to array failure. SRL and PSU have demonstrated that the formation of current filaments can result in irreversible damage. As part of this SBIR, SRL and PSU propose to use rapid real-time optical diagnostics to protect laser diodes from irreversible damage, significantly increasing their lifetime and reliability. By improving the lifetime of laser diodes, this technology will dramatically lower the cost of ownership of laser diode arrays, allowing them to be successfully integrated into a wide range of military laser hardware. | |

| Title: Building an Internet Cleanroom from Virtual Machines | |
| Abstract: In this proposal, we present an approach for building the Internet Cleanroom (IC) that represents a radical departure from prior and current Internet security tools and practices. Where today's information security tools and practices focus either on building better software, filtering mechanisms such as firewalls to prevent remote exploitation, or building tools to detect compromises, the proposed technology described here creates a safe environment for running Internet-enabled software. The system provides an environment in which intrusions or compromises present no threat to the host system or other software and data. This approach effectively eliminates all external threats from Internet-connected machines. It does not address the insider threat where users are given keyboard access to machines. | |

| Title: Policy-based Automated WAN Configuration and Management | |
| Abstract: Our project aims at developing a description language allowing network administrators to specify policies for desired configuration and operation of their networks, networked devices, and applications at a high abstraction level. We ground the language ontologies and rules in the W3C Web Ontology Language and the W3C Semantic Web Rule Language. We formally prove that our language is sound and complete. We employ incremental tests to build acceptance within user community and demonstrate through use cases and concepts of operations of DoD and commercial enterprise networks that the language is perfect for capturing and expressing cross-layer configuration policies. Our project also aims at designing a cognitive, agent-based system capable of maintaining, verifying, and diagnosing network configurations based on policies defined in our language and responding to aberrant behavior. We develop a secure, distributed knowledge base, advanced expert reasoning technologies, and distributed validation, verification, and enforcement models enabling cognitive agents to collaboratively configure and manage networks. We investigate the feasibility and system benefits for transitioning the system to DoD and commercial customers. | |

| Title: Modification of Wireless Fidelity Communication Devices to Support the Urban Warrior | |
| Abstract: TM Tech has identified an opportunity to leverage commercially available WIFI technology to support squad leader and foot soldiers in the urban warfare environment. The objective of this Phase I proposal is to determine the feasibility of modifying commercial WIFI components together with a single-chip SiGe BiCMOS ASIC to create ultra compact, portable, extended range communication devices in a USB form factor. Our initial focus is the implementation of a single-chip SiGe front-end module that increases the operational range of commercially available WIFI components. The ruggedized module is power efficient, lightweight, small and attaches to a UMPC, laptop, or PDA-type host device. At a minimum the module will be compliant with any 802.11b/g device operating in the 2.4 GHz ISM band. Line-of-sight range will be greater than 1 km at 1 Mb/s digital data rates. The module will also operate outside of the ISM band over an extended tuning range of at least 2.30 GHz to 2.50 GHz. Enhanced versions of the device could include operation in frequency bands from 900 MHz up to 5.9 GHz. | |

| Title: ABL (Airborne Laser) Detection Sensor Improvements | |
| Abstract: The first sentinel of ABL's present target acquisition suite is a passive infrared search and track sensor of 1970s vintage, which we propose replacing with HyPAWS. HyPAWS is a low-cost passive wide-field of view staring sensor. Several such units suffice to provide full 360-degree view coverage. Leveraging revolutionary sensing techniques in ongoing development, HyPAWS offers advanced detection capabilities. In Phase 1, we will complete preliminary design of the HyPAWS sensor, flowing-down ABL operating, detection, and passive-to-active handover performance requirements. We will determine the most feasible Image-Stabilization-in-Silicon (ISiS) architecture to support HyPAWS processing. ISiS will implement the equivalent of 1000 COTS CPUs executing a specialized algorithm, on a small silicon chip. Our ISiS approach will trade principally between Cellular Nonlinear Network (CNN) chip, digital processing onboard a customized VLSI chip (e.g. "structured ASIC"), or digital processing onboard a customized read-out integrated circuit (ROIC) in concert with an FPA vendor. For full-scale Phase 2 fabrication of ISiS, we will employ our research institute partner (University of Notre Dame) nanofabrication facilities or MOSIS, or otherwise secure an industry partner to exploit envisioned synergistic technology combinations. In Phase 2, we will implement and field demonstrate a brassboard prototype HyPAWS sensor, employing our full-scale ISiS. | |

| Title: Advanced Radar Data Fusion - Multiple Input Multiple Output Sensor Acquisition (MIMOSA) System | |
| Abstract: Radar targets provide a rich scattering environment that produces from 5 to 25 dB target fluctuations. The spatial dependence of target scattering has been understood for some time and it has been shown that targets produce essentially independent scattering returns when radiated from sufficiently different directions. Thus, if receivers are distributed over a wide enough area, which is the premise of MIMO radar, we can exploit the angular spread of the scattering to obtain improved performance by combining these independent looks at the target. This is essentially what is known as diversity gain in MIMO communications and it is exploited extensively in space-time coding and related MIMO techniques. Effectively, we exploit what is normally considered to be a deficiency, target fluctuations, to improve performance. In fact, other effects that are also normally considered to hurt performance, such as reflections of the returns off the ground or other objects, can also be exploited to improve performance in a similar way. The proposed MIMOSA concept will exploit MIMO technologies leading to the development of a new capability to autonomously collect, process, and fuse information from a variety of radars (either at the same or different frequencies and multiple perspectives) and from other sensors to form a single integrated picture of the battlespace. The solution will exploit MIMO technologies originally designed for RF communications applications. This approach will be used to more accurately and reliably support acquisition, track, discrimination, and engagement objectives of threatening objects across a spectrum of threat classes and environments. This novel and synergistic MIMO-based approach shows promise of providing a more accurate picture of the adversary threat cloud than any single sensor or group of sensors operating independently can offer. In order to achieve this, the fusion of data at several levels will be necessary. This will include methods for fusing multi-sensor data for 3-D imaging to discriminate targets based on multiple radar returns as well as data collected by airborne or space borne IR sensors and active LADAR devices. Further fusion of data with other radar or a-priori data will also be supported. Software algorithms and hardware that enable this synergistic fusion and interpretation of data from disparate ground-based and overhead sensors (air or space-based IR and LADAR) are expected to enhance system acquisition, tracking and discrimination of threat objects in a cluttered environment and provide enhanced situational awareness. The proposed R&D will investigate: (i) the deployment of MIMO-based radars that take advantage of antenna/spatial/frequency diversity for target detection/tracking and feature exploitation, (ii) use of robust feature aided tracking (FAT) algorithms; (iii) application of multi-modality sensor data registration/fusion schemes to support real-time performance; (iv) (vi) spatio-temporal sensor calibration to reduce bias errors; and (v) the development of 3-D imaging techniques for visualizing multiple targets and fused target track data. | |

| Title: Physics Based Modeling of Hydrometeor/ Aerodynamic Interactions due to Ballistic Missiles Radomes | |
| Abstract: Hydrometeor impact/erosion qualification evaluations of aerospace vehicle components have to relate testing carried out in ground test facilities to what the components experience in the flight environment. The size distribution and condition of the hydrometeors that impact the surface of a radome can differ substantially from what they are in the natural environment before encountering a missile's bow shock. The resulting transformed conditions of the hydrometeors have a strong influence on the magnitude and extent of any damage that results from their collision with a radome's surface. Previous analyses have concentrated on spherical raindrops, however falling raindrops greater that 1 mm are not spherical but develop a flattened shape that becomes more severe with increasing diameter. Rain is present up to roughly 5 km and can be anywhere from a small to moderate fraction of the hydrometeor population in the prevailing adverse weather. Other types of hydrometeors comprising adverse weather are present at higher altitudes where the missile's velocity is increasing. Methods will be developed to calculate what happens to the falling raindrop geometries, the prevalent geometries of irregular shaped ice particles, and additional hydrometeor types when they pass through the missile's bow shock to impact the radome. | |

| Title: Advanced Signal Processing to Enhance Target Detection & Discrimination In High Countermeasure Environment | |
| Abstract: ABSTRACT: Missile defense radars use wideband waveforms along with coherent processing to extract detailed target features and perform high range /Doppler resolution functions. Reduced RCS targets embedded in high clutter (chaff, or chaff-like fuel debris, etc.) environments present significant challenges. Closely spaced objects and decoys accompanying targets of interest inherently increase the complexity of the problem. Additionally, other forms of electronic countermeasures can also reduce the defense ability to detect, track, and discriminate such reduced RCS threat. These factors place demanding signal and data processing requirements on the sensor and may require advanced algorithms and architectures. To counter this problem, dB Research proposes an advanced signal processing technique to perform high resolution detection and imaging. This technique is based on utilizing a three-dimensional signal model that utilizes a third order Taylor series expansion about incremental, time, azimuth angle, and elevation angle. In this case, once a location of interest (where potential targets embedded in high clutter environment) has been identified by the radar, a burst of wideband waveform is used. The required signal processing includes heterodyning with respect to a fictitious scatters located at the center of the wideband cell of interest. Then spatial FFTs are used to extract target angular information. This way the problem of wideband target detection is transformed into a spectral analysis problem. The resultant angular (azimuth and elevation) resolution cells for a given range cell (time) is proportional to the spectral resolution of the spatial FFTs and is typically order of magnitude smaller that when using typical wideband waveforms and processing techniques. For example, an area of about 2x2 meter can be spectrally divided into a 128x128 cells. This way, much less clutter RCS would compete with the reduced target RCS, thus facilitating detection. Additionally, if coherent integration is used, then Doppler imaging can be accomplished where target's scatterer centers coherently integrate while other closely spaced objects would decorrelate. | |

| Title: Advanced Multisensor Fused Track and Discrimination Architecture | |
| Abstract: This effort proposes to design and demonstrate the concept of an innovative, Advanced BMDS Multisensor Fused Track and Discrimination Architecture that will enhance the generation of a Single Integrated Picture of the Battlespace. This Architecture permits enhancement of sensor-to-sensor track correlation handover of objects while characterizing their lethality for later target designation purposes. This Architecture generates a "Fused Object Dossier" of estimated "true" physical attributes, such as size, shape, and motion parameters. The "true" physical attributes from the Dossier can combined with multisensor state vector data to create a "Super State Vector (SSV)" resulting in enhanced object correlations. The significant innovation permitting the generation of the Dossier and the SSV is an object angular momentum vector direction (AMVD) estimation algorithm, the focus of this Phase I effort. Knowledge of the AMVD permits calculation of the momentum aspect angle at any time during the mission resulting in the conversion of features, such as apparent length, into a true length estimates. This enables the correlation of multiple sensor tracks on the same object being associated with the same "true" physical attributes, resulting in more robust correlations. This will be demonstrated using simulated, high fidelity radar returns generated using deciBel Research "dB_Tools". | |

| Abstract: Directed Energy Solutions (DES) and the University of Denver Research Institute propose a program aimed at revolutionary advancement of the current technology used in powering high-energy chemical iodine lasers.

The laser nozzle is a unique concept utilizing a rapid mixing section. In this Phase I effort we will utilize a unique generator laboratory to experimentally validate this concept. The goal for this generator is to reduce transit time from the generator to the laser nozzle at flow rates >20 mmol/s SDO production which will substantially increase the power output from COIL lasers. We will also test novel mixing nozzles to determine mixing efficiency using a planar laser induced fluorescence technique to measure the I2 mixing efficiency under cold flow conditions. | |

| Title: Real-time Atmospheric Disturbance Compensation Using Hardware-Accelerated Speckle Imaging | |
| Abstract: Atmospheric disturbances are a major performance-limiting factor in long-range optical systems. In particular, for the Airborne Laser (ABL) the ability of distinguish targets from a long distance is crucial for mission success. Despite the progress in optics and sensor technology, blurring in long-range imaging caused by atmospheric movements and density changes will remain an issue. Digital signal processing techniques can be used to compensate for these atmospheric effects, using algorithms like the bispectrum speckle method developed by researchers at Lawrence Livermore National Laboratories. Unfortunately, these algorithms are computationally intensive and require several seconds to process a single frame in high-end workstations, making them unsuitable for real-time video surveillance applications. We propose the development of a custom hardware processor, based on FPGA technology, which is able to implement the speckle algorithm two orders of magnitude faster than current PCs, thereby enabling real-time video feed processing. To this end, we plan to collaborate with the creators of the speckle algorithm at LLNL. Furthermore, FPGAs are uniquely suited for airborne platforms given their footprint and power consumption. For this project, we will develop a real-time atmospheric compensation solver that occupies less than 120 cubic inches and consumes less than 25 W of power. | |

| Abstract: Epitaxial Technologies' overall objective is to develop innovative detector technologies that can be used to produce enhanced quantum efficiency and high detectivity VLWIR sensors that can operate at high temperatures. The goal of Phase I will be to investigate dilute nitride strain layer superlattice material structures that are capable of enhanced gain and detectivity and then grow and fabricate them to achieve detectivity in excess of 1E10 Jones to establish feasibility of the detector concept. We will accomplish this by designing and growing dilute nitride-based strained layer superlattice detector structures and by fabricating and testing the detectors. During Phase II, we will finalize the material structure, growth process, and fabrication process of the detectors. Further in Phase II, we will design, fabricate, and test 64 x 64 FPAs and demonstrate high operating temperatures as well as high pixel uniformity and improved resolution with reduced noise. | |

| Title: High Strength Ta2C-Based Compounds for UHT Boost Nozzle Applications | |
| Abstract: Future generation propellants earmarked for DoD and MDA boost vehicles will create increasingly severe conditions (temperature, pressure and particle impingement) in the nozzle region that will prevent state of the art materials and designs from achieving the performance levels and costs being targeted for next-generation solid rocket motors. The demonstration of zero or near-zero erosion in the throat area is a much sought after goal for boost propulsion systems, since it offers direct payoff potential with respect to increased motor performance, reduced nozzle weight and lowered cost relative to current-generation of high performance rocket motors. For this Phase 1 STTR effort, the materials we propose for examination are based on high strength, high purity di-tantalum carbide (Ta2C) compositions and variants thereof. These ultrahigh temperature Ta2C-based materials will be fabricated by novel isostatic densification methods Exothermics has developed over the past few years. Due to their extremely high melting points, unique microstructures, and predicted stability against aluminized propellant exposure, we anticipate that such Ta2C-based compositions will be able to withstand 3000 - 3500C propellant flame temperatures. The principal markets that would benefit from the availability of such ultrahigh temperature materials are in the MDA and DoD boost nozzle realm. | |

| Title: Innovative Technologies Supporting Affordable Increases in Power, Efficiency, and Bandwidth for Ballistic Missile Defense System (BMDS) X-Band Radars | |
| Abstract: This Phase-I STTR MDA Proposal proposes the use of a new class of diamond-seeded solid-state material system for the manufacture of virtually all heat-generating solid-state electronics in X-band and Ballistic Missile Defense radar components and systems. In this proposal wherein much preliminary (DARPA- and MDA-funded) work has been demonstrated hitherto by the authors, all or most of the basic semiconductor devices in an electronic RF unit (e.g. GaN HEMTs, Power Amplifiers, etc.) are replaced with Semiconductor-on-Diamond based devices to enable nearly total and immediate heat extraction from the device's active region. A 4" Gallium Nitride-on-Diamond will be demonstrated for the first time here. Polycrystalline free standing CVD diamond - nature's most efficient thermal conductor - enables nearly perfect heat extraction from a "hot" device, owing to the extreme thermal conductivity of diamond (GaAs, Si, and SiC are 35W/m/K, 150W/m/K and 390W/m/K respectively; diamond ranges from 1200-2000 W/m/K depending on quality). In the proposed scheme, the device's active epitaxial layers are removed from their original host substrate and transferred to a specially treated low-cost CVD diamond substrate using a proprietary low-cost manufacturable scheme. The semiconductor-on-diamond technology proposed here may be applied to Si, GaAs, GaN, SiC, SiGe, etc. at up to 8" in wafer diameter. | |

| Title: Novel Binder Materials for IM-compliant Solid Rocket Motors | |
| Abstract: The need for munitions insensitive to stimuli possible to occur in the logistical and operational life cycle of the munition is paramount for safeguarding life and property. Research to produce IM-compliant solid propulsion systems has primarily focused in two areas: advanced case materials/designs and new propellant formulations. The energetic, low toxicity, and high fracture toughness material dicyclopentadiene (DCPD) has the potential to meet IM-compliance criteria when used as a solid propellant binder. DCPD has also been shown in 1-D chemical equilibrium codes to maintain the same specific impulse levels as HTPB when used in ammonium perchlorate/aluminum formulations. IN Space and Purdue University propose to investigate the technical merit and commercial feasibility of this promising solid propellant ingredient. The Phase I study will consist of selecting DCPD-based formulations, mixing and casting candidate formulations in various forms, analyzing their combustion characteristics including performance and ignition through hot fire testing of 3.0 in diameter motors, determining their mechanical properties, and assessing their ability to improve IM compliance through modeling and subscale sensitivity experiments. Portions of this extensive Phase I effort will be funded by State of Indiana STTR matching funds. | |

| Title: Advanced Infrared (IR) Sensor Components for Missile Defense | |
| Abstract: The DoD STTR solicitation is seeking to identify innovative technology to provide a quantum leap in performance for cryocooler systems. Successful development of such an innovative technology will result in lowering the cost and risk of cryocoolers while increasing reliability and lifetime, which will lead to increased producibility of cryocooler systems. Johnson Research & Development Co., Inc. (JRD), in conjunction with Raytheon and Tuskegee University (TU), is working on the development of two, staged solid-state cryocooler designs, one using two pulse tube (PT) based cryocoolers and the other staging a PT and a Joule Thompson (JT) system, to achieve the 0.5W @ 35K goal. These designs are inherently extremely low in vibration, which is critical for image jitter minimization, and structurally robust, essential for launch survivability. Furthermore, initial analyses predict that efficiency potential of these concepts is competitive with present day cryocooler technology. | |

| Title: Advanced Encryption Techniques for the Prevention of Reverse Engineering of the Programming Code in Military and Space Custom ICs and FPGAs | |
| Abstract: We propose the development of advanced encryption techniques to make integrated circuits more secure against unauthorized intrusion, specifically the use of innovative embedded techniques to make reprogramming of high performance deep sub-micron or nano-scale FPGA or custom ASIC systems by other than the intended recipient essentially impossible. The specific concerns addressed in this proposal regard the use of ICs having strategic importance, e.g., radiation hardened FPGAs, gate arrays, and other devices, being used by potential aggressors. As discussed in this overview, we are developing a methodology that is algorithmically robust since we make the worst-case assumption that the algorithm used to protect the device will be known or discovered by an attacker (e.g., through methodical reverse engineering). Such "deconstruction" has become common in the IC industry to the point where it is a routine part of competitive analysis at large IC manufacturers. Services are commercially available and deconstruction reports are available online for a fee. This makes the logic of any device available to any potential aggressor with sufficient resources. Consequently, a level of security that makes use of the devices themselves more expensive than fabricating copies is sufficient. | |

| Title: Advanced Infrared (IR) Sensor Components for Missile Defense | |
| Abstract: Millennium Engineering and Integration Company and Oak Ridge National Laboratory have teamed to propose development of an entirely new type of infrared detector that has the potential for providing significantly higher Long Wave Infrared (LWIR) detectivity for detector temperatures in the 180-300K temperature range than is presently available. This new detector exploits means of enhancing field emission from Carbon nanotubes, thereby enabling modulation of the field emission current by electrons excited in the Carbon nanotubes by absorption of IR thermal energy. This arrangement results in a thermal detector that has some characteristics of a photovoltaic detector because the rate at which electrons are emitted from the CCNTs is proportional to incident photon flux. Based upon this innovative new concept, we hope to achieve significant performance advantages over currently available thermoelectrically cooled or stabilized LWIR detectors. | |

| Title: Physics Based Modeling of Supersonic Rain Erosion and Material Response of Missile Radomes | |
| Abstract: The development of missile technology and systems will benefit greatly from a capability to simulate the dynamic particulate impact event(s) about the surface of the radome/shroud under aerodynamic flight conditions. An effort to develop a material response and erosion model for radomes/shrouds is proposed. The effort will identify gaps in the existing technology and database and will focus on the polyimide composite AFRPE4. This is advantageous since it is a material that performs well at elevated temperatures and loads in flight and is being considered for many different applications by MDA as an integral structural as well as an electromagnetic transparency component. The approach described will demonstrate the viability of the concept to incorporate continuum damage mechanics theory into an FEA code to model, simulate, and analyze the behaviour of the material while being impacted at supersonic velocities. Currently this capability does not exist. This effort will leverage ongoing development efforts to model composites and brittle ceramics subject to impact from raindrops and projectile. The effort will ultimately demonstrate and develop an erosion code for any composite radome/shroud material that will be directly interfaceable with the existing ATAC-3D code. | |

| Title: Passivation of Type II Superlattices for VLWIR Sensors | |
| Abstract: Very long wavelength infrared (VLWIR) detectors are highly needed for midcourse phase missile defense. Blocked impurity band detectors are capable of sensing at these wavelengths but require extremely low temperatures, in the 10K or less range. The InAs/GaSb Type II heterostructure system offers unique design flexibility for new innovative detectors. By incorporating dark current reduction techniques, we can provide the basis for 77K detection in the 15-25 micrometer spectral range. Several tasks are required to address the application of Type II superlattices for VLWIR sensors: (i) Design of a suitable structure with cutoff wavelength in the VLWIR at the desired operating temperature (ii) Optimization of the epitaxial growth conditions for VLWIR superlattice material with the goal of minimizing recombination centers, and (iii) Development of processes for uniform and reproducible sidewall passivation. | |

| Title: Advanced Infrared (IR) Sensor Components for Missile Defense | |
| Abstract: The objective of this proposal is to further explore PbSnSe detector array on Si substrate. Two approaches are proposed. One is a zero-risk incremental advance that employs a new growth condition to reduce the dislocation density. Another approach is a novel fabrication technique with high-risk but it could enable revolutionary rather than evolutionary advances. IV-VI semiconductors such as Pb1-xSnxSe can be grown epitaxially on Si substrate with a fluoride buffer layer. Monolithic mid-IR detector arrays have been fabricated on Si substrate with read-out integrated circuit and shown promising performance. The main advantages of IV-VI Pb-salt semiconductors include: (1) the large dielectric constant helps screen and localize the defect related effects. (2) The uniformity of the epitaxial material and thus the cutoff wavelength is high. This reduces the demand for powerful signal processing ROIC. (3) The low growth temperature allows direct growth of Pb-salt detector structure on Si with ROIC. Therefore, a cost-effective, monolithic FPA can be fabricated on Si substrate. Two-color simultaneous waveband operation and large formats of FPA can also be fabricated. | |

| Title: AlGaN/GaN HFETs on Silicon for BMDS X-Band Radars | |
| Abstract: In this program, we will combine commercially available AlGaN/GaN on Si FETs with short gates such that the high frequency performance (X-band and higher) can be significantly increased. The AlGaN/GaN material system has significant advantages over the incumbent technology for X-band applications; specifically, AlGaN/GaN FETs have much higher power density which translates into broader bandwidth. This bandwidth may be traded to increase PAE in the power amplifier design. Affordable and reliable AlGaN/GaN FETs that operate in L and S bands have been commercialized by Nitronex. This has been made possible largely through the use of high quality and scalable Si substrates. Nitronex is highly experienced in GaN epitaxy, fabrication, device and RF design. By working with the University of Florida and their short gate lithography capability combined with Georgia Institute of Technology and their physical simulation expertise, we will demonstrate high performance X-band discrete devices. In Phase II, we will work with systems level military contractors to develop the insertion strategy for X-band capable AlGaN/GaN FETs on Si. Based on such a strategy, the conceived solution will be implemented through the development of a MMIC solution that meets all program requirements. | |

| Title: Securely configurable gate arrays utilizing anti-tamper memory | |
| Abstract: This Small Business Technology Transfer Phase I project proposal describes a program to develop secure FPGA architectures and configuration algorithms that exploit the unique capabilities of a new anti-tamper memory technology called AT-MRAM, that provides strong protection against invasive attacks used to recover the intellectual property stored in the FPGA configuration. AT-MRAM provides protective layers, that when breached cause the data stored in the memory to be erased with no remanence. The erasure mechanism does not require applied power. The AT-MRAM protective layers also function as electromagnetic shielding, providing immunity to EM-based side-channel attacks. In addition, AT-MRAM is intrinsically radiation hard. There is not a single secure FPGA available today with an unpowered zero-remanence erasure feature that is triggered by removal of shielding layers. This unique capability will greatly enhance FPGA security. | |

| Title: Innovative Technologies Supporting Affordable Increases in Power, Efficiency, and Bandwidth for Ballistic Missile Defense System (BMDS) X-Band Radars | |
| Abstract: Under this STTR effort, the Phase IV Systems/Auburn University team will leverage Auburn University's knowledge in applied genetic algorithm optimization algorithms for RF design problems to develop an X-band radiating element with improved mutual coupling and bandwidth compared with conventional printed circuit radiating elements. The design constraints for the genetic algorithm are increased bandwidth and decreased inter-element mutual coupling, while maintaining peak directivity broadside to the element. The genetic algorithm will start with a SAR-RSW antenna due to the low mutual coupling inherent to the structure. A fitness function will be used to evaluate the output after each iteration of the GA. The fitness function will separately weight the closeness of the bandwidth, mutual coupling, and directivity measurements with respect to the objective values. The directivity fitness is required to make sure the antenna produced by the GA radiates properly. The anticipated output of the GA will be a unique antenna element design that meets the full FOV requirements with low mutual coupling characteristics of the SAR-RSW and bandwidth significantly greater than typical resonant printed circuit antenna elements. The output design from the GA will be simulated with a full-wave solver and an engineering model will be fabricated and tested. | |

| Title: Tantalum-Hafnium-Carbide and Tantalum-Hafnium-Carbonitride Materials for Boost Propulsion Nozzles | |
| Abstract: Advanced missile defense interceptors will provide our nation with the capability of defeating threats to our homeland and our deployed troops. However, the fielding of these advanced interceptors is strongly dependent upon technologies that enable production of interceptor boost nozzles capable of surviving extreme temperatures and corrosive environments with minimal erosion. Plasma Processes, Inc. (PPI) has already produced high quality vacuum plasma sprayed tantalum carbide (TaC) material. Analytical models predict that PPI's TaC will survive subscale hot fire testing. In the proposed effort, the knowledge learned during the TaC studies will be applied to the development and characterization of materials superior to TaC, such as tantalum-hafnium-carbide (Ta4HfC5) and tantalum-hafnium-carbonitride (Ta4HfC3N2). Ta4HfC5 has a melting temperature up to 265C higher than TaC, and Ta4HfC3N2 is less susceptible to thermal shock due to its expected higher thermal conductivity than TaC. Development, characterization, and testing of Ta4HfC5 and Ta4HfC3N2 is proposed to 1) increase the fundamental scientific knowledge of these ultrahigh temperature materials; 2) produce material property data to be utilized in existing performance models; and 3) determine if these materials are superior to TaC for employment as boost nozzle components. The proposed material development and low cost fabrication techniques will ultimately lead to improved performance and reduced costs for advanced missile defense interceptors. | |

| Title: A lightweight infrastructure for detection and mitigation of insider threats in distributed environments | |
| Abstract: The insider threat remains one of the most difficult to detect -- left alone to mitigate -- threats against information systems. The overall objective of the effort (Phase I and Phase II) is to produce and prototype a Distributed Insider Threat Detection System (DITDS) for distributed environments, capable of identifying and quantifying emerging insider threats against the network, allowing for timely mitigation. Instead of relying on large centralized databases for tracking the evolution of the multi-stage attacks, we propose an interactive methodology, with sensor data being fetched from the hosts as needed in the evaluation process. Our solution includes: (1) A heterogeneous, distributed sensor suite, which, under request from the DITDS manager, gather information from multiple nodes; (2) Given the readings from the multiple sensors, continuous evaluation of the network with respect to known multi-stage attack scenarios, and continuous search for new attack scenarios; (3) mechanisms centered on mobile agents for inoculating the various components of the network against a detected attack, and (4) mechanisms for integrating behavioral information about the users into the decision making process. The College of Computing at the Georgia Institute of Technology will serve as the University partner. Lockheed Martin Information Assurance (LMIA) will serve as a subcontractor, providing data sets representative of insider attacks. These data sets will be collected using LMIA's DAIWatch(TM) system. | |

| Title: Weapons Typing Assessment via Spectrally Diverse Sensors and Air Sample | |
| Abstract: This proposal will develop methods to determine the weapons type associated with Ballistic Missile Defense engagements. This development will use impact and debris track observations from active RF and passive EO/IR sensors. The goal is to increase efficacy and accuracy for which individual objects within the debris field can be tracked and characterized, when sensor fusion is employed. This information is useful to fulfill multiple MDA missions, including weapons typing and consequence management. For example the observation of a population of uniformly sized debris may suggest submunitions were present in the target, and/or the spectral observations of the debris cloud may indicate the presence of a chemical weapon. Threatening debris state vectors can be propagated to the ground for recovery or air sampling, and hazard zones for orbital platforms can be identified. The Phase 1 focus will be on the recent Aegis BMD intercept collections in order to develop the necessary track fusion, metric extraction, and data visualization tools on a recent collection with a wide variety of debris tracks. Later phases will extend this result to all MDA mission regimes, where multiple target types have been intercepted, in order to assess the utility of fusion for post-engagement weapons typing. | |

| Title: Advanced Radar Data Fusion | |
| Abstract: The TSC team proposes to develop a new generalized Space-Time Adaptive Processing (Generalized STAP) algorithm that discriminates among classes of scatterers. The new generalized formalism is applied to the problem of 3D ISAR imaging of the reentry vehicle (RV) or another object in the ballistic missile threat complex that suppresses radar dipole clutter, using multiple ground-based radars operating at the same or different frequencies. The generalized STAP algorithm is a novel synthesis of ideas from TSC's successful 3D radar imaging programs with the techniques of adaptive signal processing. TSC and the Sensor and Array Processing Laboratory of the University of Arizona will demonstrate the new Generalized STAP signal processing technique for two important cases: The first is an ultrawideband scenario involving S- and X-band radars that operate coherently to synthesize an ultra-wideband 3D image via Sparse Band Processing (SBP) technology. The second is a geographically distributed coherent constellation of next-generation ground based X-band radars. In Phase I, TSC will simulate ultra-wideband and multisensor radar data and develop prototype radar signal processing algorithms for these two cases. | |

| Title: Test-Ready Model for Flexible Systems of Systems | |
| Abstract: Complex, dynamically reconfigurable, distributed systems are common in today's component-based mission-critical systems. Conventional testing tools used for certifying such systems are less likely to succeed in such less-predictable and evolving domains where underlying assumptions with respect to the structure of the system are constantly being violated. Furthermore, given the vast complexity of such systems and impracticality of exhaustive testing of the overall multidimensional state space, new methodologies and computational infrastructures are necessary to deal with dynamically reconfigurable systems. We propose a computational framework that could facilitate scalable and sound reasoning approach by localizing the detection of faults that occur at run-time. The premises of the proposed approach are (1) local certification of components with respect to their contractual specifications, (2) packaging of the contracts, test cases, and built-in self test mechanisms with the component using a metadata wrapper technology, and (3) use of associated run-time interface violation detector mechanisms to detect deviations from acceptable behavior as components reconfigure and interact at run-time. By embodying the behavioral interface models with semi-automatically generated wrappers, the proposed technology will support services for run-time contract violation checking and built-in-self testing even when the underlying component technology does not provide built-in introspective reflection capabilities. | |

| Abstract: This Small Business Technology Transfer (STTR) Phase I program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPa,cm) TaC-based composites for use as zero-eroding rocket nozzle throat components for high performance, reduced-cost boost propulsion systems. UES will apply a novel "Top-Down Process" to control the microstructures of the composites. This approach will produce a very unique grain structure that can offer high strength as well as fracture toughness. Thus, a high thermal shock resistant material is anticipated. Hot-pressing will be used as the means for densification during the Phase I feasibility study. In the Phase II study, a sinter/HIP process will be developed for near-net shape fabrication. During Phase I, UES will collaborate with the University of Dayton Research Institute to conduct hot-pressing, mechanical evaluations, and microstructural characterization. UES will process the powders and also evaluate the high temperature properties. | |

| Title: Advanced Data Fusion Using Bayesian Track-Before-Detect | |
| Abstract: Dispersed sensors offer more information to tracking systems than a single sensor and this additional information should improve the performance. Typical approaches only use information from a single sensor to initialize tracks and then use measurements from other sensors to improve the track estimate. In a new approach, the PMHT will be enhanced to not only identify new track starts, but also should yield better tracking performance by determining if a new track is realistic. With this enhancement to the PMHT, this emerging tracking algorithm will then be able to utilize its excellent clutter rejection to track targets in dense clutter environments. We also believe we have a solution to the optimistic covariance of the PMHT, and we will explore the feasibility of this solution during this effort. Therefore, we are proposing using the enhanced PMHT as a composite tracker on several platforms utilizing simulated sensor data. We think that the enhanced PMHT will improve the single integrated picture across the composite trackers; reduce or eliminate redundant, spurious, and broken tracks; better maintain tracks throughout the missile flight; and deal with out-of-sequence measurements. In addition, the PMHT will demonstrate its superior processing speed. | |

| Title: C-RAM: Cognitively-Based Rapid Assessment Methodology | |
| Abstract: The essence of information assessment is the process of distinguishing signals from noise. In the military, intelligence analysts are constantly searching for signals that might suggest an adversary's intentions. In each case the analyst must search through a quantity of data, searching for meaningful patterns within the preponderance of noise. In many contexts, the volume of data available is too much for an individual analyst to consider. In these cases, it becomes necessary to divide the work among a team of collaborators. The team of 21st Century Systems, Incorporated and Colorado State University is pleased to propose to research and develop the C-RAM concept, Cognitively-Based Rapid Assessment Methodology. C-RAM manages multiple users interacting with multiple information sources, and provides both textual and visual methods for viewing these data. The C-RAM system allows the analysts to organize the information using different presentation modalities. These separate presentations are used to collect and fuse information. Our goal is to develop a set of tools and agents for collaborative information assessment that will improve group performance by reducing the cognitive effort required to perform these assessment tasks. Intelligent software agents assist the user in visually decluttering their information and directing their attention.BENEFITS: Our goal is to develop a set of tools and agents for collaborative information assessment that will improve group performance by reducing the cognitive effort required to perform these assessment tasks. The first planned product is a decision support software program that allows for subjective input, from multiple sources in determining the outcome of mission critical and time sensitive planning where dispassionate evaluation of unlimited quantities of disparate information is necessary. It will provide an innovative solution that will guarantee the integrity and authenticity of automated collaborative information assessment and data uncertainty analysis functionality in a GIG-NCES (Global Information Grid - Net-Centric Enterprise Services) framework. Initial targeted customers outside of the military services would be Federal government agencies and commercial agencies (C2 Centers, Mission Commanders, Medical Industry BOD, and Airline Industry Executives to name a few) who deal with fast paced, dynamic information management and decision-making environments. These environments are typically characterized by complex and uncertain data, high stakes decision, and decentralized command structures. | |

In the past, false alarms, missed failures, mishandled preventive maintenance scheduling, and underutilized resources have resulted in poor operational performance. Recent advances in information systems technology allow intelligent monitoring of these many measurement points. Emerging capabilities are partial recovery, forecast of impending problems, and increased operational use during abnormal operations. What is needed is an automated health monitoring capability for electric machinery and systems that have high fault detection, and low false alarm. Additionally, the capability performs "self-healing" functions to reduce down time of electrical machinery. The team of 21st Century Systems Incorporated and the University of Missouri is pleased to propose the development of a tool that will provide the automated health monitoring and self-healing capability and decision support necessary to improve the survivability of our Naval vessels. We call our Phase I concept Proactive Predictive Machine Maintenance (P2M2). We will be leveraging existing work in health monitoring and embedded systems techniques combined with cutting edge research into advanced sensor design and intelligent computing to design a Fault Diagnostics, Prognostics, and Self-Healing Control system.BENEFITS: The list of potential military applications for these capabilities is quite long. The 21CSI team fully intends to build and transition key technological elements; embedded systems, machine learning, CBM technology, etc.; to suitable Navy and DoD large electrical machine systems. 21CSI will build the distributed software, with agents, tailored to the specific applications. Once the prototype agent-based system is reasonably developed (likely, midway through Phase II), we will commence transition. The Navy will be the potential government customer, the P2M2 system will be placed in-line between the sensor and the ship's monitoring system (ICAS or similar) to monitor, diagnose, predict, and ultimately control Navy electrical machinery. $1.2 M - $1.5M and ~18 months will be required to complete the P2M2 Model development. The majority of the funding is required for investigating P2M2 user requirements, for building a P2M2 model, and to build a prototype. A modest portion of the necessary funding (~$100K) will come from 21CSI IR&D. The vast majority will come from Phase II, Phase II Options, and Phase III SBIRs. 21CSI has strong DoD application marketing capabilities due to its market penetration for more than ten years with good contacts and a strong reputation with most SETAs. In addition, 21CSI has informally spoken with potential customers regarding P2M2 for electrical machinery and learned that the planned capabilities and pricing are very attractive to those potential customers. Once the system is accredited, 21CSI will launch a campaign to educate DoD, other government agencies, and commercial customers on the capabilities and applications of the P2M2 Prediction Software for electrical machinery. If this technology is proven to be feasible after Phase I and meets requirements at the end of Phase II, it will be transitioned to ONR's Advanced Integrated Power System (AIPS) program under the Enterprise and Platform Enablers Future Naval Capability (FNC). The technology will be demonstrated 1) in simulation on ONR's Virtual Test Bed (VTB) and 2) in a full scale medium voltage demonstrator together with global power system management capabilities currently being developed. The commercial customer will be primarily airlines and cruise ship companies. The P2M2 system will help the airlines reduce operating costs and provide timely and required maintenance upon landing. There are currently numerous vendors of each of the key technology components required for developing the Fault Diagnostics, Prognostics, and Self-Healing Control Proactive Predictive Machine Maintenance (P2M2); however, no one is offering a platform independent, COTS-based integrated solution. 21CSI has several dimensions of sustainable competitive advantage for the P2M2 system once development is completed and the system is accredited. | |

| Title: Power Harvesting for Encrypted Wireless Sensor Clusters | |
| Abstract: Among the Navy's goals for new ship construction are to achieve cost savings in ship installation, to increase survivability of the vital communications infrastructure, and to enable manning reductions through highly automated ship operations. The rapid advancements and proliferation of wireless technology makes it a primary candidate for adaptation to machinery health monitoring, condition based maintenance (CBM), and machinery control in support of these objectives. The particular challenges that must be addressed to enable integrated wireless sensing to meet these objectives are communications through and around steel ship compartments, secure wireless communications, and most importantly minimizing power requirements enabling the application of emerging parasitic or energy scavenging power technologies. The Navy's Phase I STTR topic N06-T020, "Power Harvesting for Encrypted Wireless Sensor Clusters" presents the opportunity to address these challenges through the development of energy scavenging electronics adapted to shipboard environments and innovative low power wireless sensing elements.BENEFITS: The results of this STTR are applicable to wide variety of sensor monitoring systems. By developing a wireless energy scavenging sensor node, the solution presented in Phase I will enable tunneling a wireless network through walls where wire based communication and power distribution simply isn't a viable option. In the Phase I, 3 Phoenix, Inc (3Pi) teamed with North Carolina Agricultural and Technical State University (NCA&T), and Ferro Solutions, Inc (FSi) will develop a robust self powered energy harvesting scalable wireless architecture that will significantly reduce the network installation cost, provide a highly survivable control system, and enable technology insertion of the new system onto existing platforms. The team will focus not only on the energy harvesting and storage but will also address the problem at the source and investigate ultra low power electronics solutions and approaches for efficient energy management. | |

| Title: 3-D Fiber Reinforced, Thermally Conductive Rotor Sheaths | |
| Abstract: Military helicopters rotors contend with rain, ice, sand, and flying debris. To prevent damage to the expensive blade protective sheaths or coatings are applied to the leading edge of the rotor blades. A 3-D woven composite sheath with high thermal conductivity fibers running through the thickness can offer the best qualities of both metal sheaths and elastomer coatings. Infused with an elastomer matrix, it will achieve excellent sand erosion resistance. Based on a 3-D fiber architecture, it will provide excellent resistance to both impact damage and rain erosion. High conductivity graphite fibers running through the thickness of the composite will mimic the thermal conductivity of the metal sheaths. In this Phase I effort, 3TEX and its partner CCM-UD will produce a 3-D fiber architecture composite rotor sheath prototype. 3TEX will design a 3-D woven preform that incorporates several functions, including impact resistance, local stiffening, and through thickness thermal conductivity. CCM-UD will infuse the preform using VARTM infusion techniques that can include local tailoring of the resin for impact or strength or high temperature. Prototype sheaths will demonstrate the production processes while material coupon testing will determine rain erosion, sand erosion, and impact resistance, as well as thermal conductivity.BENEFITS: Composite rotor sheathes based on 3-D fiber architecture should offer the best performance attributes of both elastomer coatings and metal sheathes. While maintaining the anti-icing functionality of metal sheaths, the 3-D composite rotor sheathes will provide longer component life. The longer component life should not come at a high component cost. The 3-D fiber performing process is sufficiently economical to compete in the E-glass boat hull market, while the VARTM infusion processes reduce tooling costs and speed the part production, so the part prices themselves should be competitive with existing sheaths. However, increasing the time between replacement of the sheaths immediately translates to reduced maintenance costs and higher helicopter readiness levels for the Navy. The payload and range of Vertical Take-off and Landing (VTOL) aircraft, such as helicopters, are highly sensitive to aircraft weight. The 3-D composite rotor sheathes will weigh significantly less than the current metal sheathes. Thus, this new technology sheath will increase the range and payload of every fleet helicopter currently using metal sheaths, such as the V-22. The proposed effort then will offer reduced maintenance costs and increased VTOL range and payload. | |

| Title: Fault Diagnostics, Prognostics, and Self-Healing Control of Navy Electric Machinery | |
| Abstract: ACTA Incorporated and the Center for Systems Reliability (CSR) at Sandia National Laboratories propose a seven month STTR Phase I Project to demonstrate the feasibility of developing Fault Diagnostics, Prognostics, and Self-Healing Control of Navy Electric Machinery. The new generation of Navy high power electric ships and electro-mechanical machinery challenge the predictive maintenance of ships' combat effectiveness, survivability, crew safety, and operational cost. A data driven real-time prognostic health management (PHM) system is proposed to meet these challenges by providing continuous health monitoring for fault tolerant systems using prognostic data. The PHM System will track the likelihood of future system or subsystem failure and initiate appropriate actions in real time to maintain system performance.BENEFITS: The proposed work will provide an advanced fault diagnostics, prognostics, and self-healing control capability, ensuring cost effective and highly reliable electrical machinery systems to improve warfighting effectiveness and ensure a "limp home" capability. Systems currently exist in the navy that assesses the condition of engineering plant machinery. The linkage of diagnostic information like the Integrate Performance Analysis Report (IPAR) now mandated by the Fleet and the evolving Enterprise Performance Analysis Report (EPAR) lack direct linkage to repair and maintenance actions the associated impact on mission capability and ship sustainment. The proposed Evidence and Consequence Engine technology is ideally suited to provide solve this elusive need and to provide a near real-time solution to support the genesis of true self-healing control technology in shipboard systems. | |

| Title: Phosphorous-Containing Epoxy Resins for Room Temperature VARTM | |
| Abstract: The Navy intends to start using a significant quantity of composite structures in surface ship construction in an effort to decrease costs as well as to reduce the visibility of the ships to radar. The large size of the target structures necessitates the use of low temperature, non-autoclave processing techniques such as Vacuum Assisted Resin Transfer Molding (VARTM). In the recent past, most marine composites were based on glass fibers, but due to the mechanical property requirements of the newer applications, carbon fibers will be required as reinforcements for future structures. Currently, the matrix material of choice is a vinyl ester resin based on its superior mechanical properties. Vinyl ester resins work well with glass fiber reinforcements, but do not adhere well to carbon fibers, leading to lower overall composite performance due to the poor fiber-matrix interface. This Phase I program proposes the development of a phosphorus-containing epoxy resin that would not only improve the quality of the fiber-matrix interface in VARTM-processed composites for shipboard applications while meeting the Tg requirements, but would also offer enhanced fire retardance relative to current resin systems. BENEFITS: The phosphorus-containing epoxy resins for room temperature VARTM processing will find immediate application in military applications both in Naval vessels as well as in aircraft. Transitions to the civilian marine and aircraft industries are expected. | |

| Title: Development of Lightweight and Low Cost Advanced Structural Materials for Off-board Surface Vessels (OBVs) | |
| Abstract: The ACR led team proposes an affordable manufacturing technique for complex-geometry composite components to be used as stiffened curvilinear structural panels and variable shaped fuel and ballast tanks for Off-board surface vehicles. Through the use of its AquapourT and AquacoreT water-soluble tooling materials, ACR has previously demonstrated that different composite material systems based on epoxy and BMI types of matrix systems could be fabricated including sandwich composites, while Dr. Jack Gillespie at UD-CCM has successfully performed design and testing of complex composite structures. The Aqua tooling materials are capable of creating composite geometries that could not be fabricated any other way. BENEFITS: By demonstrating the fabrication of vinyl ester/carbon composites (VE/carbon) using its washable tooling materials, complex geometry parts can be made and inserted into Off-board surface vehicles. | |

| Title: Development and Optimization of Innovative 3D "Confetti" Miniature Antennas for HF Communications | |
| Abstract: Aerotonomy, Incorporated, and our research institution partner Georgia Tech Research Institute (GTRI) propose to Design and optimize a miniature 3D fragmented "Confetti" antenna for application to broadband voice communications over the frequency range of 2 to 30 MHz. The Confetti antenna is an arrangement of partially interconnected wires on a three-dimensional grid. The concept is similar to the Fragmented Aperture Antenna (US Patent 6,323,809), but the Confetti antenna is 3-dimensional, whereas the Fragmented Aperture is two-dimensional. The antenna is designed using automated optimization to meet specifications that depend on the intended application of the antenna. The method and generality of this class of antennas promise to provide performance that approaches the best that is theoretically possible for a wide range of applications. The goal for this research is to design an antenna of only 500 cm3 volume and only 30 cm in any dimension that can be tuned to operate efficiently over 2 to 30 MHz with up to 150 W transmission power, while achieving 3 KHz instantaneous bandwidth. While this combination of goals is ambitious, we believe this innovative antenna can offer performance that will move the state-of-the-art significantly closer to these ideals.BENEFITS: There are many obvious opportunities for commercialization of this technology in the DoD. HF communications systems are used extensively by all branches of the U.S. armed forces, as well as Homeland Defense, intelligence agencies, civilian law enforcement organizations, and resource management organizations (i.e. Forest Service), as well as private industry and amateur radio operators. The optimized, extremely compact multi-modal Confetti antenna technology that will be developed during this project represents a revolutionary step in broadband antenna system performance while meeting the goals of minimal size. The small size of these antennas will allow increased distribution of effective communications capabilities to users in the field, thereby benefiting a large group of potential users. In the private sector, there are a number of companies engaged in the development and deployment of advanced, small scale communications systems that could benefit from the integration of antennas based on Confetti technology to their product lines. | |

| Title: Delamination Resistant Coating System for Zinc Sulfide Domes and Windows, Utilizing a Compliant Layer. | |
| Abstract: Zinc Sulfide (ZnS) is the most practical material for infrared transparent domes and windows operating at long wave infrared wavelength. Hard outer coatings have been applied to ZnS to protect it from rain and sand erosion. Theoretical analysis of multi-layer coatings suggests that a compliant layer between the hard outer coating and the ZnS surface may improve resistance to rain impact damage. In this program, a bonded ZnS window is proposed and an innovative nano-composite polymer material is developed as the compliant layer in addition to index matching for the hard coating. This novel compliant layer will absorb the energy created by the impact of rain and sand, and subsequent crack propagation, thereby protecting the ZnS dome from damage and preventing delamination of the coating system. Once the hard outer coating is severely damaged, it can be removed and replaced leading to life-cycle cost savings. The nano-composite polymer material itself has strong adhesion ability and can be used from - 70 oC to + 100 oC. It has high transparency (>90%) to long wave and mid wave infrared radiation. It is even transparent in the 0.6 - 2 micron region when its thickness is about 100 microns. In Phase I, we will develop the nano-composite polymer and bonded ZnS windows for the Whirling Arm Rain Rig test.BENEFITS: Delamination of hard outer coatings on ZnS domes and windows may be damaged by the impact of rain and sand. This degrades performance and may lead to excessive replacement of windows. For missile domes, the possibility of catastrophic failure is a serious concern. The proposed novel nano-composite polymer materials can bond hard protective coatings to infrared domes and windows to improve their resistance to rain impact damage. There are numerous commercial applications for the material. The proposed nano-composite polymer can also be used to bond zinc selenide domes and windows. It can be used as an immersion materials and glue to bond infrared optics and fibers in infrared imaging for the applications of fire fighting, industrial control, driver's aids, traffic monitoring, biomedical imaging, pollution detection, and security systems. | |

| Title: High-Power and Low Loss Mid-Wave IR Fiber-Optical Switch | |
| Abstract: Agiltron, in collaboration with Tufts University, proposes to realize MWIR fiberoptic switches that meet all the required performance specifications for the new type of compact airborne IRCM applications. The approach is based on our extensive experience in volume production of fiberoptic switches of industrial leading performance as well as in-house chalcogenide glass fabrication capability. This program also leverages Agiltron's sole supplier position in producing high power (>5W) fiberoptic switches to the commercial market. The proposed designs have the desirable attributes of ultra-low loss, insensitivity to vibration/shock and temperature variation, long operational life, high power handling capability, and scalability to a large number of fiber ports, as well as low fabrication cost. We have successfully demonstrated a MWIR fiberoptic switch based on this design. The Phase I will further optimize the design as well as the fabrication processes to reach the state-of-the-art performances that have not yet been obtained.BENEFITS: Fiber-optic switches are increasingly being used in telecommunications, bio-sensing, laser marking, laser machining, laser micromachining, and in the forensic sciences. Mid-wave infrared radiation is a valuable tool for spectroscopic investigations of organic compounds associated with oil exploration as well as chemical analysis. | |

| Title: High-Power Fiber-Optical Switch for Infrared Countermeasure (IRCM) Laser Applications | |
| Abstract: We propose to develop a new fiber optic switch for IRCM applications. The purpose of the phase I program is to demonstrate the feasibility of a high power 1xN (N=2-6) fiber optic switch operating in the mid IR region. By carefully optimizing each individual optical component, the optical switch will have a minimum net insertion loss of less than ~0.25dB at given laser wavelengths in the mid IR region. A pathway to develop a highly ruggedized optical switch for military applications is outlined and will be vigorously pursued during the tenure of the phase I program. The technical goals of the phase I program are to (a) experimentally demonstrate the feasibility of the key performance parameters and (b) to conduct preliminary packaging design of a ruggedized switch. BENEFITS: The Navy has interest in infrared counter measure systems that use lasers to protect aircraft from infrared-guided threats. Among the counter measure architectures under consideration is a centrally located laser with distribution by optical fiber to multiple tracker-pointer output assemblies. This approach reduces volume, weight, and cost. An enabling technology for this architecture is a robust fiber-optic switch. This program would provide the Navy with a high performance switch with low insertion loss and the capability to handle high power. The switch will also be important for civilian applications such as laser marking, laser machining, laser micromachining, and forensic science. | |

| Title: Conventional Training Versus Game-Based Training | |
| Abstract: Game-based training (GBT) has been touted as a promising medium for achieving improved training objective performance outcomes and increasing learner motivation, particularly in military training environments. However, there is little empirical research upon which to make informed decisions about when, where, or even if applying particular game elements to training is effective. The primary objective of Phase I is to investigate the feasibility of successfully integrating GBT into training curriculums. Formal empirical evaluation of the effectiveness of applying specific gaming elements to achieve specific training objectives will be conducted in Phase II. The first objective of Phase I will be to identify core training objectives that are likely to benefit from the introduction of GBT, and to begin development of a taxonomy that links game elements, training objectives, and training environments. The second objective will be to develop a plan for implementing selected game elements in an actual training environment and assessing the effect on learning outcomes. Storyboards of the plan will be created to allow evaluators to assess the feasibility of incorporating the plan into an existing training program. If Phase II is approved, a functional prototype of a segment of the GBT plan will be created and tested.BENEFITS: There is much interest in developing and incorporating innovative and effective instructional methods such as game-based training into current training curriculum; however, there are few guidelines on how to best implement this approach. The development of a theoretically-driven and empirically-supported decision-aiding tool that specifies when and how specific gaming elements should be integrated into training and instruction would allow instructional designers in a variety of domains to make informed decisions about to best use game-based training to enhance learning and performance outcomes. The decision tool could ultimately be applied to training and instructional development in a wide range of organizations from the military to K-12 classrooms to private companies wishing to design more effective training curriculum for their employees. Any industry that must provide rapid training to individuals on hard-to-learn equipment, where practice is helpful, would be aided by GBT. Likewise, many team-based industries, such as process control, emergency medical response, and transportation, as well as many business-oriented companies could benefit from a tool that provides guidance on how to maximize the effectiveness of GBT. | |

| Title: Power Generating Backpack | |
| Abstract: The purpose of the Power Generating Backpack is to allow soldiers to generate electricity while walking. This backpack represents an alternative to bulky battery systems soldiers often carry on the battlefield. The adoption of this backpack will result in a lighter load, thus improved comfort and mobility for combat units. The design APECOR is proposing will be transparent and of minimal impact to the user, so as to not disrupt the normal use of a backpack. Current state-of-the art employs a one dimensional technique to translate human motion to vertical load motion to generate electricity. APECOR is proposing to investigate the feasibility of a two or multi-dimensional approach to power generation. In the two-dimensional approach, the load will be suspended inside the backpack by vertical and horizontal axes, while in the multidimensional approach we will take advantage of the load's mass (50Ibs) to implement a pneumatic (pressurized cushions) system. During the walking process, the load will bounce against pressurized cushions strategically placed inside the backpack to produce enough displacement for a linear or motor generator to induce electricity. BENEFITS: The power generating backpack will find applications in military and recreational markets. This backpack will essentially be useful not only to soldiers, but also to climbers and hikers, who venture in remote locations. To date, most power generating backpacks take advantage of small solar cells. The introduction of the motion based power generating backpack will add versatility to existing backpacks since they could be used in any conditions, not just on sunny days. The added benefit is that the system will reduce the stresses of walking with a load on the user. | |

| Title: Development of Lightweight and Low Cost Advanced Structural Materials for Off-board Surface Vessels (OBVs) | |
| Abstract: Off-board vehicles deployed in littoral environments are subjected to severe operational loads, including wave slamming, high-speed collision with debris, and underwater explosions. They additionally serve as sensor platforms, and would benefit from reduced self- and radiated noise for towed array performance and mine defense. Consequently, we propose to exploit the flexibility of design offered by modern composites to achieve a novel OBV hull design integrating beneficial structural, shock, and stealth characteristics. Novel design features are threefold. First, the composite hull cross-section contains a compliant viscoelastic core material offering isolation from low-level transient events and acoustic isolation and damping, in addition to its structural function. Second, we propose a novel composite stiffener design that integrates structural function with large shock protection, by minimizing stress concentrations at structural discontinuities. Third, to address the occurrence of stress concentrations at geometric discontinuities state-of-the-art forming techniques are proposed that allow for the fabrication of highly curved junctions without appreciable loss of strength. Our proposed Phase I effort includes concept performance predictions (Applied Physical Sciences, Inc), static and dynamic validation tests (University of Massachusetts- Advanced Composite Materials and Textiles Research Laboratory), and a benefit trade-off analysis against weight and cost (Marine Applied Physics Corporation.) BENEFITS: The successful completion of the proposed effort will yield a composite hull design that significantly improves the shock and impact survivability and sensor related mission performance of the Navy's OBV or similar marine vehicles. Certain of our novel hull design features may be patentable and have application to small commercial or pleasure boats, e.g. our composite forming technique or integrated stiffener-mount design. | |

| Title: Impact of Gaming Attributes om Measures training Effectiveness (IGAME) | |
| Abstract: Traditional military training is becoming increasingly constrained by logistical challenges, geographic distribution of personnel, and limited resources, leading to an increased interest in game-based training approaches. However, training developers need to better understand how to develop game-based training that is motivating and engaging, but still pedagogically sound. The IGAME effort proposes to develop a predictive model-based tool, and associated metrics, to assess the impact of gaming attributes on training outcomes, IGAME will inform training designers, prior to investment, of the tradeoffs in training effectiveness associated with varying gaming attributes. Aptima will base the IGAME on a theoretical framework that links gaming attributes to Navy-relevant training outcomes. Aptima will also identify trainee characteristics and training context variables that may influence the relationship between gaming attributes and training outcomes. In Phase I, pilot tests will expand the theoretical framework and validate the functions and algorithms that drive the IGAME tool. In Phase II, Aptima will conduct additional experimentation to further expand the theoretical framework, validate the model, and compare game variants to define when and how to use games for training. To ensure success, the Aptima team will apply their knowledge of game-based training, predictive modeling, model based experimentation, and experimental design.BENEFITS: The IGAME tool will provide training designers the ability to anticipate the impact of gaming attributes on training outcomes. The IGAME tool will aid training designers in determining what knowledge and skills can effectively be trained within games having of varying attributes. In addition, the PERFORM tool will allow training designers to understand, prior to investment, the tradeoffs in training effectiveness associated with varying gaming attributes. The framework that constitutes the IGAME tool will allow a transparent view of the current state of research on game-based approaches to training. This transparency will provide researchers with a sound understanding of what previous research has addressed and where further experimentation is required. | |

| Abstract: Technology continues to advance at faster and faster rates. Often new technology is created with little regard for the impact to the humans who must use this technology. One new technology the Navy is considering using is autostereographic displays, which permit users to see a true 3D image without wearing cumbersome glasses. Aptima and its partner, Dr. Dirk Reiners of Iowa State University, will conduct a meta-analysis of the HSI research in 3D displays to show where 3D technology improves total system performance without HSI impacts. After completing this analysis, we will draft research based guidelines for the use and screen design of autostereographic displays. These guidelines will serve as the framework for a toolkit (GRID 3D: Guidelines and Rules Instrument for Displays in 3D) to be built in Phase II. GRID 3D will allow developers to quickly and easily follow guidelines and will provide the code for appropriately designed screen components. GRID 3D will save time and money by putting process knowledge into use. The guidelines will ensure that displays are in line with best practice research, and the toolkit will ensure that these best practices are followed.BENEFITS: The anticipated benefits are as follows. The GRID 3D will enable the display designer and/or systems design team to: . Design ergonomically correct 3D displays based on researched guidelines for 3D interface designs. . Reduce the display design life cycle by providing 3D display components. . Determine which components are more effective for a task and the potential technological impacts on operator performance. . Ensure that best practices/standards are followed, producing a consistent operator experience across 3D display tools. . Provide evidence that 3D displays will improve operator performance. | |

| Title: Decision Making Constructs for a Distributed Environment (DCODE) | |
| Abstract: Modern information technology enables decision makers to access and filter large volumes of information; however, this technology does not necessarily translate into improved decisions. While much technology has been created to deliver information, relatively little has been developed to help decision makers organize, assess, and systematically apply that information to evaluate decision options. While some strides have been taken to address this situation (e.g., MIT's EWall provides a virtual space for information organization; DCODE allows decision makers to record and share judgments) additional steps are needed to help translate increased information into improved decisions. Specifically, this technology must be (1) extended to rate or recommend decisions between courses of action (COAs); (2) validated empirically; and (3) transitioned to the operational community where it is greatly needed. Aptima, Pacific Science & Engineering, and the Naval Postgraduate School will address this problem by developing a real-time COA assessment tool: the COA Assessor in Real Time (CART). This tool will build on existing, ONR-sponsored technologies - EWall and DCODE - enabling the project team to draft algorithms, user interface concepts, implementation plans, validation plans, and transition partnerships in Phase I that will be the basis for a real-time COA assessment tool developed in Phase II. BENEFITS: Current tools available for decision makers focus more on information knowledge building; very little is available to actually facilitate the difficult decision making process. The COA Assessor in Real Time (CART) will allow decision makers to take advantage of existing technology for collecting, organizing, and making judgments on information; CART will use this information to make real-time recommendations about the best COAs. | |

| Title: Intelligent ILBE Generator & Energy Management (I2GEM) | |
| Abstract: The work proposed here augments the increasing body of research on capturing energy from walking. It focuses on the aspects associated with converting the captured energy, in the form of physical displacement, into an electrical form. The proposed Power Generator Back Pack is based on a Vernier Hybrid Machine (VHM) and magnetic gearing. The Vernier hybrid machine is a member of the family of variable-reluctance permanent magnet machines. Magnetic gearing converts the slow physical velocity to a higher frequency flux. This leads to a reduction in the size and weight of the backpack. Three-phase ac power from the linear generator is converted to desired dc output by the Intelligent Energy Controller (IEC). The IEC contains the power converter (a digitally controlled rectifier followed by dc-dc converter), battery recharger, sensor suites for monitoring battery state of charge and a processor that supervises all activities. The IEC uses adaptive control and optimum battery recharge routines to maximize efficiency as load levels and generator output vary. Additional features include data logging for post-mission maintenance, real-time diagnostics and displays. BENEFITS: Mobile power sources such as batteries often add great additional weight to a backpacker's load. As a result, there is great interest in harvesting electrical power from the energy expended during walking in a variety of situations. Investments made under this proposed STTR will increase Archangel's market potential in power sources. A number of markets have been identified for application of this developed technology. Power Generator Back Pack, once available to the commercial market, will help consumers to use their electronic equipment in remote location, where no other source of energy is available. Different versions of this backpack could allow disaster relief workers, explorers or soldiers to go out into the field with fewer heavy replacement batteries for cell phones, GPS instruments, night vision goggles and many other portable electronics. Refinements of the design could also lead to backpacks that are more comfortable and perhaps better for the back. | |

| Title: Maximizing the utility of high-resolution ensemble meteorological forecasts for planning and responding to hazardous releases | |
| Abstract: The two primary motivations for this work are: First, to provide forecasts of dispersion of a hazardous release and associated uncertainty (or "error bars") based on the available ensemble MET data. Second, to provide an efficient and user-friendly tool for decision makers supporting both deterministic and ensemble forecast MET data as well as resulting dispersion model forecasts. To achieve added value the ensemble forecasts will be downscaled to high resolution, bias corrected, and weighted as part of this process. During Phase 1 AER will demonstrate the feasibility of the proposed methodology by assembling a prototype system that leverages existing technology. This will allow multiple schemes for displaying probabilistic information from the ensemble and for evaluating, ranking, and weighting individual ensemble members to be studied and demonstrated. To satisfy these requirements, a toolkit based on a framework to support both data processing and visualization will be developed. By providing for a common representation scheme for both MET and ATD data sets, the toolkit will allow for intermediate data sets to be visualized and to diagnose how processing assumptions and choices propagate through the methodology. Additional tools and/or processes can be readily applied within this framework to extend its capabilities as needed.BENEFITS: The methodology developed will improve planning and forecasting hazardous releases and will be valuable to government agencies and to industry, especially to those agencies or companies that might be targets of terrorism and/or must handle hazardous substances as part of their function or business. These include elements of DOD, DHS, DOE, oil production facilities, ports and transportation hubs, chemical plants, and others. | |

| Title: Aerodynamic/Structural Mistuning Technologies for Assessing IBR/Blisk Repairs | |
| Abstract: New technologies for assessing how blending affects structural and aerodynamic mistuning will be developed using the combined strengths of Blade Diagnostics Corporation and Duke University. BDC has developed an approach for identifying aerodynamic mistuning from engine data that will be further developed under this STTR. Duke will develop new methods for computing the effect of blending on the aerodynamic damping and excitation forces that act on blended blades. The accuracy of Duke's method will be assessed using the BDC aerodynamic mistuning identification software and benchmark data provided by GE Aircraft Engines. Consequently, at the end of this STTR we will have demonstrated that we can use the BDC software to process NSMS data and extract information about the excitation forces and damping that act on individual blades, and that we can use the new Duke University CFD codes to predict how changes in the blades geometry from blending affects the aerodynamic forces and damping that acts on the blade. These tools will be integrated into a mistuning inspection machine (MIM) that BDC is developing for the Air Force. The MIM can then assess how blending a blade affects the likelihood of HCF failure when the Blisk is in the engine. BENEFITS: Blade Diagnostics Corporation will integrate the aerodynamic mistuning capability, developed in this STTR with their Mistuning Inspection Machine (MIM) being developed for the Air Force) so that the effect of aerodynamic mistuning as well as structural mistuning will be taken into account when calculating how blending a particular blade will affect the vibratory response of the IBR/Blisk when it is put back into service. In effect, the added aerodynamic capability developed in this STTR will transform BDC's MIM into a virtual engine test for blended blades. Consequently, at the end of this effort a validated technology will be in place that will allow the DoD to use relatively low cost blending operations to repair a larger number of IBRs/Blisks while reducing the likelihood of HCF failure from mistuning. This capability fits directly with the R&D goals of the DoD's VAATE program (Versatile Affordable Advanced Turbine Engines) as well as the more recently launched Propulsion Safety and Affordable Readiness (P-SAR) initiative. Looking at the future from the opposite viewpoint, an IBR/Blisk-laden world without the described capability would mean a large number of damaged components ($100K to $500K each) that can't be returned to service or that need to be repaired using alternative processes that are much more expensive, e.g. blade replacement. Clearly, fleet readiness would be adversely affected. The proposed effort thus offers a capability that is both timely and appropriate. With GE Aircraft Engines as an active participant in the program, there is every expectation that the capability developed in the STTR will be promptly transitioned to manufacturing and operational service to meet what are already important Air Force and Navy needs. In addition to meeting important DoD needs for cost effective repairs, it should also be noted that the latest models of commercial aircraft engines are also using IBRs/Blisks. As a result, the proposed new technology has dual use application to commercial as well as military engines. | |

| Title: Functionalized Single Walled Carbon Nanotubes for High Performance Composites | |
| Abstract: The objective of the proposed research is to use chemistry to modify single-walled carbon nanotubes (SWNTs) and engineer the interfacial interaction with polymers to synthesize composite materials with enhanced mechanical, electrical and thermal properties. We will conduct research on the synthesis and properties characterization of SWNT-reinforced composites based on epoxies and vinyl esters. Our approach is to engineer the interface between SWNTs and the polymer matrix by tailored chemical modification of SWNTs, which is designed to impart processability and chemical compatibility of the nanotubes with the matrix and to allow controlled cross-linking with the polymer chain. The proposed effort will build on our expertise in chemically modified SWNTs and achievements in the development and characterization of advanced SWNT-reinforced nanocomposites. We have assembled a multi-disciplinary research team that includes renowned experts in the fields of nanoscience, nanoengineering, carbon nanotubes and composite materials, which together possesses the necessary expertise to accomplish this ambitious project which has the potential to significantly advance the nanocomposites utilized in naval, defense, aerospace and commercial industries.BENEFITS: The developments in this project will lead to single-walled carbon nanotube reinforced epoxy and vinyl ester composites with enhanced performance. Markets for such advanced composites are widely available in the naval, defense and aerospace industries. Additionally, the developed composites are promising candidates for structural components in civil transportation and can find applications in automobile parts, fascia for buildings, reinforcement of bridges, and ducts. Other applications include coatings, adhesives and electronics. | |

| Title: Advanced System of Systems Design Capability | |
| Abstract: Chesapeake Marine Technology, with suncontractors Anteon Proteus Engineering and the Georgia Institute of Technology, is proposing to demonstrate the feasibility of a ship-centric design tool that can be used to evaluate design trade-offs and optimize ship characteristics, with the ship considered to be one "System" in a System of Systems (SoS)environment. The proposed work is based on modifying the existing Anteon ETC FlagShip Designer software package and its Smart Product Model environment and framework to analyze and optimize ship design features in a broader, System of Systems context. The Phase I work will: (1) identify the software modifications and additions required to transition to the SoS framework; (2) determine the feasibility of completing this transition and define the corresponding Phase II work plan; and (3) demonstrate the operation of the planned system using the example of a CG(X) vessel design trade-offs as they relate to operating in joint air defense scenario.BENEFITS: The proposed project would provide the Navy with a tool that could be used to evaluate and optimize designs for future ships, ship systems, and groups of ships for operations in a wide variety of mission scenarios. This tool would permit these evaluation and optimization exercises to be completed with the ship considered to be one level in a multi-level system of systems, and would permit propogation of sub-system capabilities and limitations throughout the scenarios. It would also permit inclusion of the characteristics of external systems such as threats into the process. Using such a tool, would permit the Navy to evaluate and optimize design features for any system within the system of systems with respect to ultimate capabilities to satisfy multiple operational requirements. | |

| Title: Miniature Electronic Sniffer for Navy Vertical Take off Unmanned Aerial Vehicles (VTUAVs) | |
| Abstract: The use of Unmanned Aerial Vehicles (UAVs) in warfare, reconnaissance, and surveillance activities has increased dramatically over the past decade and, for the first time, offers cost effective, intelligence-gathering capabilities without placing soldiers and sailors at unnecessary risk. Current UAV platforms have already been equipped with a limited range of sensors such as miniature audiovisual equipment and global positioning systems for battlefield surveillance activities. The next generation of battlefield UAV will require new and advanced on-board sensors for detection of Weapons of Mass Destruction (WMD) based on specific Biological, Chemical, or Radiological materials. We propose to employ revolutionary new air sampling technology based on electrospray ionization that was developed by Nobel prize winning Chemist Dr. John Fenn, VP Research at our firm, in collaboration with our group of scientists. The ESI sampler offers unprecedented performance parameters including low power, light weight and high sampling efficiency over an enormous range of particle sizes ranging from molecules to microscale particulates. We propose to apply Dr. Fenn's miniature vapor sampler as the key enabling technology for UAV's equipped with detection based on Laser Induced Florescence of select trace species for the identification of explosives, chemical toxins, and other hazardous materials on board ship.BENEFITS: Portable Chem/Bio Detector for Coast Guard, DoD, Port Facilities | |

| Title: Navy Applications of 4th Generation Deeply Coupled Computing Architectures | |
| Abstract: Warfare is changing; there is a need for airborne and space-based sensor systems to detect small, highly maneuverable targets against a strong clutter background in the presence of jamming. Space-Time Adaptive Processing (STAP) is a new signal processing technique for advanced radar systems that allows for performance enhancements over conventional approaches. Current power, weight, and size constraints make the real-time implementation of full degrees-of-freedom STAP techniques on airborne/spaceborne platforms impractical. CPU Technology and University of Maryland Institute for Systems Research propose to investigate and demonstrate the advantages of applying 4th generation deeply coupled programmable SOC technology, called the QX4, and other adaptive hardware elements to provide airborne platforms with the computing capacity required to perform real-time STAP techniques. It provides 8.5 GFlops of 64-bit performance at only 8 watts of power. The adaptive hardware will utilize floating gate technology to accelerate STAP radar processing. We will code a STAP algorithm and execute the software on a single x86 microprocessor, a QX4 array, and a QX4 array with adaptive hardware to measure their relative performance. Other metrics will include size, weight, power and accuracy. We will also investigate adding STAP cost-effectively to existing radar processors. BENEFITS: Space-Time Adaptive Processing (STAP) enhances the ability of radars to detect targets that might otherwise be obscured by clutter or by jamming using a two-dimensional filtering technique. This capability enables a radar to see items under vegetation and provides much improved information in urban scenarios where clutter is extremely high and the targets are small. Our goal is to make a high speed real-time STAP radar processor small enough and with minimal power so that STAP can be used by traditional airborne sensor platforms such as the E-2C as well as smaller aircraft such as fighters, helicopters and UAVs. It could potentially be used for the larger missiles as well. Multidimensional processing such as found with STAP is used in many applications including mobile communications, video processing, medical imaging and radar processing. Sensor fusion and autonomous operation could also potentially benefit from the compact performance throughput of QX4 and adaptive hardware techniques. | |

| Title: Novel Tooling for High Speed, Precision Machining of CMCs | |
| Abstract: Advanced propulsion systems for the Joint Strike Fighter (JSF) aircraft require the use of advanced materials for longer life, reduced weight, and increased performance. Ceramic matrix composite (CMC) materials have the potential to realize these benefits; however, the high cost of finished CMC components make wide implementation impractical. To reduce these costs, new, innovative fabrication technologies are required that enable substantial processing speed increases to drive down the expense of machining and the cycle time of implementation for advanced materials. Creare proposes to develop an advanced machining system (AMS) that will increase the processing speed 100% or more for the machining of CMCs and other aerospace materials by leveraging existing programs with novel tooling approaches. Such an increase in the processing speed will dramatically reduce both overall cost and cycle time. Because our solution prolongs tool life, the resultant use of sharper tools will reduce the induced residual stresses in the machined part, improving fatigue life. Our innovation is readily integrated with existing machine tools, minimizing initial capital costs. Thus, our solution is effective, affordable, flexible, and easily integrated with current manufacturing operations.BENEFITS: Aircraft engine manufacturers will be able to significantly reduce the cost of machining advanced materials for military and commercial systems. The increased affordability of these advanced materials parts will expand the market for these materials into automotive, heavy equipment, construction, and consumer products. | |

| Title: A Portable Swaging Machine for Aircraft Carrier Purchase Cable Terminals | |
| Abstract: The Navy is interested in a swaging tool that can be used to attach arresting gear purchase cable terminals on ship. Swaging is a well understood process, and there are many suppliers of adequately powerful machines. In fact, a large swaging machine is used at Lakehurst NAS to attach terminals to the cross deck pendants. However, these machines are too large and cumbersome to be used in the shipboard environment. Creare proposes to develop a high power density swaging machine that is lightweight, portable, and used by shipboard personnel with modest training. In Phase I, we will develop a conceptual design for the portable swaging machine based on a technology previously developed by Creare for precision metal forming. During Phase I, we will also conduct proof-of-principle tests which demonstrate that the new process and equipment will provide comparable quality to existing methods. Our preliminary design indicates that the machine footprint could be as small as seven by four feet with a height of five feet and could weigh as little as 3,700 lbs. During Phase II, we will build a prototype and demonstrate performance with appropriate pull-tests and non-destructive evaluations. BENEFITS: This portable swaging machine technology will eliminate the labor intensive and inconsistent speltering process currently used to attach wire rope terminals on Navy aircraft carriers. The portable swaging machines will allow usage in cramped pouring rooms as well as movement throughout the ship. In addition, we are teamed with Felss GmbH, a worldwide leading supplier of custom swaging machines, to provide these machines to the Navy and commercialize our results. | |

| Title: Automation of Analysis Model Creation | |
| Abstract: Traditional finite element methods require conversion of a CAD model into an alternate geometric representation called the finite element mesh. Tools like Cubit, developed at Sandia National Laboratories, have greatly reduced the time to mesh. However, it is still expensive to produce a complete analysis and difficult to have that analysis affect the design cycle in a timely manner. Our studies have shown that 80% of the modeling effort is spent modifying the geometry so that it can be meshed. In this proposal, we present a method called isogeometric analysis that eliminates the need for the traditional meshing portion of the model preparation. It utilizes the mathematical representation of the CAD model to create the analysis model. This proposal will specifically examine the modeling issues surrounding isogeometric analysis and the tools that are required to make this new analytical method usable in production design and analysis settings.BENEFITS: The size of the Computer Aided Design (CAD) industry is estimated at $5 - $10 billion, compared to $1 - $2 billion for the Computer Aided Engineering (CAE) industry. Only the best funded organizations can afford the time required to use CAE to its fullest extent because of the problems inherent in the current Design to Analysis (D2A) process. We believe the current D2A process is a growth inhibitor to the CAE industry. The approach outlined in this proposal would effectively eliminate the current problem and bottleneck inherent in today's process, that is, producing a usable mesh from an existing geometry in a timely manner. This is a potentially disruptive technology that could both displace current technologies and open new markets for the tools described in this proposal. | |

| Title: Waterjet Wake Characterization Suite | |
| Abstract: Bubble generation and entrainment in the transom region of a surface ship, along its hull, and in breaking waves are major ship signature contributors. For advanced ships such as the LCS, another source of air entrainment is added with the propulsion waterjets interacting with the free surface in the transom region. While significant research on breaking waves bubble generation exists, little is known about waterjet propulsion impact on bubbly wakes. Such wakes provide an excellent opportunity to wake homing torpedoes because of bubbles large acoustic cross section. Therefore, it is imperative to develop computational tools capable of predictive analysis for design optimization of bubbly wakes of waterjet driven ships. DYNAFLOW and ARL at the Pennsylvania State University propose to develop a suite of tools for modeling the waterjet driven ships bubbly wakes, conducting acoustic analysis relevant to wake homing threats, assessing threat performance in engagement simulations and conducting experiments to validate and refine the models. A suite of CFD codes known to reproduce conventional ship wakes properly will be used and modified by adding physical models of the waterjet free surface bubble entrainment mechanisms, which will be developed through experimental observation and modeling. BENEFITS: The proposed tool suite can be used for design evaluation of waterjet propelled surface ships. The developed models for bubble generation, propagation, and acoustics can be also combined with other CFD methods and could benefit commercial sectors such as fast ship industry, food manufacturing, oil and gas industry, chemical industry, etc. | |

| Title: A Non-Invasive Method to Functionalize Single Walled Carbon Nanotubes | |
| Abstract: This Phase I STTR project will further develop our technique for uniformly dispersing single walled carbon nanotubes into polymeric resins. This project will specifically aim to provide them with a mechanism for anchoring themselves to an epoxy matrix during curing in such a way that they are able to accept and absorb an applied load. The successful development of this technology will result in new, light weight, thermoset composites that have extraordinarily high flexural, tensile and impact strengths and can be easily molded into any shape desired. They will also be useful for reinforcing the weak link in interlaminate composites, the delamination at the interface between the thermoset matrix and reinforcing fibers. The ability of poly(m-phenylenevinylene-co-2,5-dioctoxy-p-phenyle nevinylene (PmPV) to separate large ropes of SWNT into smaller ropes and individual nanotubes by first encasing them, also promotes the solvation of long carbon nanotubes in thermoset resins. By modifying the side chains attached to the PmPV polymer's backbone via addition of reactive groups, we will be able to both increase the amount of SWNT uptake in the resins and make the load transfer from the thermoset matrix to the SWNT more effective.BENEFITS: High strength thermoset composite materials made using this technology will have considerable applications in the military because of their unique combination of properties including exceptionally high strength, light weight and stealth capability. The aerospace industry will also be interested in this technology because of its potential for use in fabricating airplanes, retrievable satellite launch vehicles, reusable space craft etc., which will be both exceptionally light in weight as well as extremely durable. This new technology will eventually be applicable to many other industries, including: the recreational and sports industries, for use in such things as snowboards, skies, light weight racing bikes, tennis rackets, golf club shafts, fishing rods, etc.; and the electronics industry, because it will provide a material that will be easily molded to any shape that has the ability to be to readily dissipate both electromagnetic interference and heat. | |

| Title: Ultra-Linear High Efficiency GaN based microwave integrated Circuits | |
| Abstract: The goal of this program is to develop high linearity and high efficiency power amplifiers through innovative ultra linear transistors and digital signal processing (DSP) circuit linearization techniques for airborne or UAV applications. Specifically, we will demonstrate average output power, PAE, and inter-modulation distortion (IMD) of 150 Watts, 50% and -50 dBc respectively for the L- band monolithic microwave power integrated circuits. The proposed L-band monolithic microwave power integrated circuits will be based on a combination of novel semiconductor device and circuit design to achieve high linearity, high efficiency and output power. In Phase I, we will design, fabricate and test the ultra-linear GaN FETs and demonstrate 10 dB power gain, and 10 watt output power and minimum power added efficiency of 45% as well as third order intercept point (IP3) greater than 25 dB above the 1 dB compression point (P1dB) at L-band frequencies. In Phase II, we will develop prototype high linearity-high efficiency power amplifier architectures and demonstrate 150 watt average output power with peak-to-average power ratio between 8 to 12 dB, 50% PAE, 30 MHz instantaneous bandwidth and -50 dBc IMD.BENEFITS: This proposed project would result in the commercialization of ultralinear, power efficient, high power amplifier modules which will be used to produce the next generation of airborne communication systems. The power amplifiers that can be developed using this technology will benefit the US Navy's E-2 Advanced Hawkeye program and naval shipborne communication systems where antennas in close proximity place a premium on linearity and efficiency. In addition, it will benefit a variety of DoD tactical missile defense programs, where power efficient phased arrays are critical. Commercial applications include components for wireless and satellite communications. | |

| Title: STTR Friction Stir Processing for Superplastic Forming | |
| Abstract: Friction Stir Processing (FSP) is an emerging technology that can be used to pre or post-process a range of materials, including aluminum, to locally modify material properties. It is known that FSP can be used to enhance material properties for improved superplastic forming (SPF) behavior of aluminum. This can potentially allow for dramatic cost reductions of SPF and aluminum fabrications, allowing the combination to be viable in applications where previously they were not viable. To-date, many fabricated components have excluded use of aluminum for several reasons, including poor formability, difficulty joining, and significant distortion, increasing cost and complexity in applications where aluminum might be considered. This technology combination can eliminate these problems. The project discussed in this proposal aims to determine feasibility of FSP in combination with SPF in Naval applications. Both commercial and technical feasibility will be determined, with the objective of obtaining knowledge of when and which applications this technology is feasible. The commercial feasibility will involve investigations of potential applications to determine the characteristics that allow for commercial feasibility. An application will then be selected for which technical feasibility will be determined. This will involve a coupon level investigation which will demonstrate technical feasibility for the application. BENEFITS: It is anticipated that there will be a significant number of benefits related to the implementation of friction stir processing in combination with superplastic forming. These would include but not be limited to 1) Allowing aluminum to be used in a cost-effective manner where it has been previously deemed uncompetitive 2) Allowing for weight reduction. 3) Allowing for more complex shapes to be formed in aluminum, subsequently causing a a) Reduction in number of components b) Reduction of amount of joining, specifically welding and riveting c) Reduction in distortion d) Improved quality e) Ability to fabricate shapes not previously manufacturable. f) And ultimately lowering cost. There are numerous potential commercial applications for friction stir processing in combination with superplastic forming. These applications would typically benefit from aluminum's lightweight properties, but aluminum has not been used due to the limitations and cost of implementing aluminum into a fabrication. There are applications throughout the transportation industry and the military. In the Navy, doors, hatches, pallets, carts, and complex superstructure sub-assemblies could be considered. In land transportation, doors, frames, and body panels are applications of interest. In addition, general industry could also have applications. Multi-sided aluminum enclosures would be of specific interest, where these fabrications are currently made of numerous parts and part consolidation could be achieved with this technology. | |

| Title: Aircraft Electrical Power System Diagnostics and Health Management | |
| Abstract: Prognostics and health management is a critical technology for accurately predicting impending failures and providing a decision process for replacing components before actual failures occur. This is particularly critical in aircraft Electrical Power Systems. Significant gains in maintenance decision making, safety, system availability, productivity, and cost savings, could be realized by the Navy with a capability that predicts impending failures in these systems. This effort investigates the feasibility of exploiting advances in monitoring and prognostics technologies to develop a comprehensive health and usage monitoring system capability for aircraft electrical power systems. Considerations include the application of a real-time, sensory- updated, residual life based prognostics methodology to provide the current and predicted degradation states of critical components such as generators, converters and batteries. The effort researches and characterizes the faults and physical phenomena of the degradation process, researches condition monitoring technology options, characterizes the patterns in the sensory information to develop an appropriate degradation model , and identifies the modeling approach required to model the evolution of the component degradation and predict its residual life based on identified failure thresholds. A system definition, capability implementation plan, and a basic proof-of-concept validation of the technical approach are part of this effort. BENEFITS: The prognostics technology developed under this effort can be easily applied in other domains such as sea, space and ground vehicle platforms, to advance the implementation of Condition Based Maintenance (CBM) principles. In addition, there is a big potential for commercialization. For example, the prognostics technology resulting from this effort can be applied in other industries including, commercial aviation, power utilities, automotive and any commercial plants where failures in large scale manufacturing systems have a great economic impact. | |

| Title: Aircraft Electrical Power System Diagnostics and Health Management | |
| Abstract: Global Technology Connection with our partners (Oak Ridge National Laboratory, Innovative Power Solutions and Boeing Phantom Works) propose the development and integration of diagnostic / prognostic technologies into an overall vehicle health management for P-3 aircraft's electrical power systems. Phase I effort will concentrate on the P-3 generators: 1) conceptualization of diagnostic / prognostic architecture and its deployment; 2) identify key parameters to measure to differentiate between various failure modes and normal aircraft operational modes / environments; 3) use QFD to select appropriate sensors according to weight, size, ease of integration, etc.; 4) develop and prototype data-driven algorithms for generator diagnostics and prognostics based upon electrical signature analysis feature extraction; and 5) feasibility of deploying diagnostics / prognostics for P-3 generators based upon an assessment of accuracy, memory and computation requirements, scalability and cost of system. The outline of a technology roadmap and Phase II development approach / schedule that contains discrete milestones for product development for P-3 generators and extension plans to converters and batteries will be provided. Phase II will capitalize upon the findings of Phase I research and will proceed to finalize the design and demonstrate a proof of concept diagnostic / prognostic technology for P-3 generators. The design will be finalized and a prototype system based on the design concept(s) proposed in Phase I will be fabricated. Through laboratory testing and characterization experiments, the viability of the system's ability to diagnose failure modes and predict remaining life for the P-3 generator will be demonstrated. A detailed plan for software / hardware certification, validation, and method of implementation will be provided. Phase III encompass final optimization of the prototype system and user interface for the Navy P-3 aircraft and other Navy / DoD aircraft systems.BENEFITS: The results of this project will assist the U.S. Navy initially and other government or industry sectors to eventually deploy a diagnostic and health management technology for the P-3 aircraft's electrical power system. When integrated into an overall vehicle health management system, such practices will reduce substantially the risk of false ID of faults while achieving accurate fault detection, reduce maintenance costs, increase the availability of aircraft systems and improve their reliability in the execution of critical missions. The commercial aircraft, electric power generation and automotive industry will also benefit from the integration of the technology. | |

| Title: New Material Compositions that Expand the Operating Domain of Piezoelectric Single Crystals | |
| Abstract: At the present time, large-sized PMN-PT piezoelectric crystals, 3" diameter by 8" long, of high quality, can be grown directly from the melt and are commercially available. The objective of this proposal is to demonstrate the feasibility of expanding the operating domain of the PMN-PT based piezoelectric crystals by chemical doping and compositional refinements. Although the piezoelectric properties of PMN-PT crystal products are qualified to the military, and are commercially used in medical ultrasound imaging (and a variety of acoustic transducers), the coercive electric-field strengths and thermal stability need to be improved particularly for large signal/high energy applications. This is very important for Navy sonar transducers. For acoustic sensors, such as hydrophones and vector accelerometers, that require high signal/noise ratios, lowering of the dissipation factor is a key parameter while maintaining the giant-piezoelectric response characteristics. Radiation with high energy particles (e.g., neutrons) can localize "defects" that pin domain wall mobility. It expected that selected radiation damage will enhance coercivity. It is well known that the PMN-PT solid-solution system is the only one that is near congruent solidification, thus enabling the direct growth from the stoichiometric melt in a most cost-effective manner. This proposal focuses on new compositions that must be near congruent melting. Thus, the proposed work for new compositional refinement to PMN-PT based crystals will be of immediate applicability to the growth of large crystals, thus expanding the operating domain of piezoelectric single crystals.BENEFITS: The proposed work will enhance the piezoelectric performance of PMN-PT based crystals by chemical doping and compositional refinement using our proprietary and cost-effective Bridgman growth method. The proposed work is targeted for high-drive applications for single crystals in Navy sonar, torpedo guidance, torpedo counter measures, sensors, vibration control, shape control, position control, and also for commercial applications such as medical ultrasound imaging, nondestructive testing, etc. We anticipate domain-engineering will increase the properties of the final transduction devices. | |

| Title: STTR Friction Stir Processing for Superplastic Forming | |
| Abstract: Friction stir welding (FSW) is a solid state joining process with unique characteristics that offer opportunities for cost savings, new fabrication methods, and new structural designs. FSW eliminates many of the problems associated with fusion welding techniques. In addition, FSW generates a "stir zone" microstructure that consists of very fine, equiaxed grains that are ideal for post-weld forming operations such as superplastic forming. Superplastic forming (SPF) with diffusion bonding (DB) has been used in titanium alloys in the past to create low-cost, integrally stiffened components with significant geometric complexity. This powerful combination of processes offers considerable design flexibility and low production costs for high-performance applications, especially in the aerospace industry. Multi-sheet SPF/DB structures with complex external geometries with integrally constructed internal stiffening elements are used in numerous aerospace applications. By replacing DB with FSW in aluminum then using SPF for panel structures, a new technology emerges that will have a vast number of applications in commercial and government aerospace and land based transportation systems. The effort defined here will develop and demonstrate processing methods for combining FSW and SPF. FSW/SPF panels will be built and tested to validate the overall process, as well as examining material properties. BENEFITS: The lightweight yet structurally strong panels using FSW/SPF will reduce weight and cost in military applications: navy ships, ground based vehicles and aircraft. The same benefit will apply for commercial transport aircraft. The potential applications are vast and will revolutionize an entire segment of manufacturing for the light, strong panels that comprise the backbone of these applications. Eventually, with the development of rapid manufacturing methods, this technology will be an important component in automotive manufacturing. | |

| Title: Polymer Based, Thermally Conductive and Erosion Resistant Boot Materials/Concepts for Rotor Blade Leading Edge Protection | |
| Abstract: The leading edge of the V-22 rotor blade is made of titanium and nickel abrasion strips bonded to the composite substrate. Although effective for rain erosion protection, nickel and titanium show poor sand erosion resistance. In addition, this metal and composite hybrid configuration limits working strain and fatigue life. This hybrid concept also hampers field serviceability and increases the operating and support cost of the rotor blade by inhibiting removal and replacement of the leading edge. It also necessitates frequent inspection to detect incipient fatigue cracks in the metal to ensure flight safety. The Navy is interested in removing the metallic leading edge strip and replacing it with a polymer based, field serviceable and thermally conductive erosion resistant boot materials/concepts directly over the existing composite substrate of the rotor blade. In this proposal, heat conductive fillers, fibers and fabrics will be combined with Hontek erosion resistant molding resins to form molded boot. Finite element analysis techniques will be used to determine the effect of fiber architecture and orientation on the conductivity of candidate molding resins. BENEFITS: It is anticipated that this effort will provide a light weight and conformable erosion protection system for the composite leading edge on current and emerging VTOL/STOL aircraft such as V-22 Osprey. This effort will eliminate the need for frequent inspection to detect incipient fatigue cracks in the metal leading edge, reduce acquisition and operating costs, enhance blade fatigue life, improve mission safety, reduce need for spares, simplify field serviceability and reduce total ownership cost (TOC). The molded erosion protection systems have universal applications to the entire fleet of helicopters and rotorcraft operated by the Navy and the Army. | |

| Title: Alternative Room Temperature Cure and VARTMable High Temperature Resin Systems for Large Scale Composite Ship Component Manufacturing | |
| Abstract: This Phase I STTR proposal is to designed to utilize the fundamental properties of POSSr nanotechnology to provide a new higher Tg and fracture toughness ambient cure epoxy matrix for use in Vacuum Assist Resin Transfer Molding (VARTM) manufacturing. Nanostructured ambient cure epoxy matrices based upon Polyhedral Oligomeric Silsesquioxanes (POSSr) will be reinforced with carbon-fiber and glass-fiber reinforcement packages using VARTM processing with no post curing to determine physical properties. The technical approaches proposed in this work focus on the synthesis and formulation of epoxy resins with nanostructured entities in order to provide elevated glass-transition, mechanical performance, reduced viscosity, and VARTM processability, relative to existing commercial ambient cure epoxy systems. POSSr type nanocomposite reinforcements increase the Tg of polymeric resins by reducing chain motions through increased chain rigidity. POSS will be utilized in this research through two primary mechanisms: (i) POSS cages that contain catalytic metals and functional groups that enhance the extent of curing for epoxy resins beyond that normally realized at ambient conditions and (ii) replacement of specific portions of epoxy monomers with POSS functional epoxides.BENEFITS: The proposed formulations will present the opportunity to study the effects that nanoreinforcement has on the glass transition and key physical properties of epoxy-type nanocomposites. The result enable an ambient cure low-viscosity epoxy that has high Tg, high fracture toughness, excellent fiber adhesion, improved flame resistance and that can be manufactured using conventional wet lay-up processing technology including VARTM. The resin will have direct commercial us by the Naval fleet, and as solid rocket motor case, and as encapsulants and underfill resins for commercial electronics. | |

| Title: RF Waveform Library Reader | |
| Abstract: Digital cross correlation represents the ideal method of realizing the optimal (matched) filtering of the wide variety of time dependent waveforms used by the DoD and thereby the maximum probability reception in high EMI/dense signal environments. Direct from RF, direct reception is increasingly feasible as fast clocking digital technologies such as SiGe, III-V semiconductors, and superconducting electronics became mature. Combining direct reception and digital cross-correlation on RF waveform seems the ideal performance path to software define radios. The digital reference waveform must, however, be delivered high clock speed if the subtleties of the waveform are to be reproducible. Unfortunately, the speed of cheap mass memory seems destined to behind high speed logic by at least 10X. Thus a new, affordable arbitrary bit stream generator box that muxes large COTS memories to high output speed is needed.BENEFITS: a | |

| Title: A Charge Prediction Tool for HSU-based Suspension Systems | |
| Abstract: Impact Technologies and Georgia Institute of Technology, with the support of L-3 Communications, propose development of a prototype software tool that promises to significantly reduce the maintenance burden associated with EFV suspension system setup & calibration required for different mission mixes and/or in the event of HSU replacement. While the current procedure requires vehicle track removal and the use of jack stands to determine the proper amount of HSU gas charge, the proposed solution would quickly and accurately estimate required gas charge for a given mission mix and vehicle configuration (gross weight, CG, etc.) in the EFV's fully operational state. Given a concise set of user inputs, a constrained multi-objective optimization routine will solve a hybrid suspension model consisting of both a physics-based response surface model and a data-driven Neural Network. The aggregate of these two modeling approaches is designed to capture the complex interdependencies between suspension system parameters while still enabling efficient optimization of HSU gas charge settings. Using a Matlab/Simulink based development environment, USMC and L-3 provided data/software and in-house development tools, the Impact/GA Tech team will be able to develop requisite technologies and demonstrate the ability to generate a deployable charge prediction module. When this module is integrated with an intuitive Graphical User Interface (GUI) and other standard utilities on a maintenance laptop or the EFV's on-board computer, significant increases in EFV operational availability (Ao) will be attainable and remote, in-field, repair capability can be realized for the first time. Furthermore, the development team will design this software system with multi-platform applicability in mind such that recurring development costs for similar FCS vehicles can be minimized. BENEFITS: In the event that this program extends through Phase II development, it is highly anticipated that a validated and DO-178B Level C/D certified software for in-situ HSU charge prediction will yield reduced maintenance man hours (MMH) and increased operational availability (Ao) for the EFV and as well as for any future FCS/MEFFV platforms with similar suspension designs. Consequently, the return on investment (ROI) potential for this program is very high for the DoD. Impact Technologies has an excellent SBIR commercialization track record and as an engineering consulting and custom s/w development firm, is well suited to see the proposed system through to deployment and beyond. | |

| Title: Fault Diagnostics, Prognostics and Self Healing Control of Navy Electric Machinery | |
| Abstract: Impact Technologies, collaborating with the Georgia Institute of Technology and Northrop Grumman Ship Systems, propose to develop and demonstrate a real-time diagnostic and prognostic system for assessing, predicting and accommodating for faults/failures of critical electric power system components including power converters and electro-mechanical drives. The innovation of integrating advanced diagnostics and prognostics with a self-healing capability to improve system reliability and mission readiness for the Navy's next generation electric machines is the focus of this effort. Implementation of this concept requires incipient fault detection techniques to provide longer predicted horizons prior to failures, operational history, and fault progression models in order to make accurate and repeatable decisions regarding the remaining life predictions. The Impact/GA-Tech/NGC team's approach uses innovative electronic fault detection and reasoning algorithms to analyze data from several sources including electrical and environmental sensor measurements, model estimates, and usage conditions. Up-to-date assessments of the electrical system health and remaining useful life of critical components will be made possible via an on-board embedded processing system, which continuously updates prognostic models with sensed data, assesses fault severity, and predicts the best fault accommodation strategy to meet mission objectives. The proposed electrical system fault detection, isolation and accommodation approach will be demonstrated with a Motor/Generator/Drive test bench adapted for use in this program and with data from the DD(X) Advanced Induction Motor (AIM) supplied by NGC. Additional plans have been discussed with NGC to demonstrate the technologies on their full-scale AIM system and ONR sponsored virtual test bench VTB during Phase II, if awarded.BENEFITS: The development and integration of embedded diagnostics, prognostics and self healing control for Navy electric systems will provide many benefits including: Improved safety and readiness associated with system operations; reduced life cycle or total ownership costs; optimized maintenance intervals and prioritized task performance. Furthermore, the work will contain many generic elements that can be transitioned to a broad range of other commercial applications. The integrated diagnostics and prognostics approaches, techniques, and specific algorithms could also be implemented in a wide range of civilian hybrid power applications as well as in power plants, utilities, transportation, and telecommunication industries where reliable backup power is essential to sustain critical services. | |

| Title: Conventional Training Versus Game-Based Training | |
| Abstract: This proposal outlines a plan to create a toolkit consisting of: 1. A methodology derived from theory and research on human performance training (HPT), research on learning, and instructional design; 2. A 3D taxonomy/matrix that maps training objectives and learning processes with game characteristics, in order to guide decision-making processes for choosing and using specific game-based training approaches; 3. Guidelines for using the methodology and taxonomy/matrix to choose game-based training solutions, or to design new games and/or approaches; and 4. A prototype tool that provides guidance for developing game-based training solutions and calculating return on investment. BENEFITS: The primary benefits of our development path are that the Navy and the Department of Defense will be provided with means to evaluate and select appropriate training modes among conventional and game-based approaches that will find application in all the Services. Commercialization within the Navy and other components of DoD will be driven by the need to select training modalities appropriate to learning objectives, cost- benefit, and other factors. On the commercial side, there is high demand for flexible training products that have been proven in the military domain, and we will target this market based on opportunities identified during Phase I. | |

| Title: Enhanced Flight Simulator | |
| Abstract: Modern flight simulators utilize combinations of motion, visual stimulation, and occasionally tactile body stimulation. Despite advances in these fields, simulators remain limited in the amount and type of motion simulation they can impart to a pilot. Direct vestibular stimulation can generate continuous sensed motions, and therefore holds promise for improving flight simulators by incorporating vestibular cueing with more traditional stimulations. Our solution is based on combining a small, lightweight motion base and a high-end visual display with a vestibular stimulation device. Incorporating vestibular cueing into a flight simulator will allow us to leverage the motion simulation generated by the vestibular system to design a motion platform that is smaller and lighter than conventional platforms, while still providing the full system with far increased capabilities over traditional flight simulators. The team assembled for this work is ideally suited to carry out the research and development of the proposed system. The clinical team from the Mayo Clinic includes expertise in military flight physiology as well as decades of experience in vestibular studies. The Infoscitex team is similarly equipped to tackle the system designs and move the project towards a commercial product.BENEFITS: Incorporating vestibular cueing into a flight simulator will allow us to design a motion platform that is smaller and lighter than conventional platforms, while still providing far increased capabilities over traditional flight simulators. This will be of great interest both to the military and to the entertainment industry. In addition, the results obtained will be the first necessary steps to developing an artificial vestibular system. Such a device has the promise of a considerable market in a patient population suffering the after-effects of disease or traumatic injury that has affected their native vestibular system. | |

| Title: Thermally-Conductive Nanocomposite Elastomer Boot System (TCNEBS) for V-22 Rotor Blade Leading Edges | |
| Abstract: The metal sheath used to protect the V-22 aircraft rotor blade leading edge against sand, rain and ice erosion, and provide heating to prevent ice buildup, is heavy, rigid and expensive. An elastomeric boot can offer lower weight, flexibility, abrasion-resistance and field repairability. However, elastomeric boots have exhibited delamination and creep failure caused by high centrifugal loads and sand and rain droplet impact damage. These elastomeric boots also have poor deicing characteristics. Infoscitex and Texas State University propose to develop a thermally-conductive, nanocomposite elastomer boot system, called TCNEBS, that provides sand and rain erosion-resistance, reinforcement against centrifugal shear forces and protection against rain droplet impact damage. The TCNEBS will exhibit high thermal conductivity through the thickness, enabling rapid thermal deicing and can be adhesively bonded to the leading edge in the field as a premolded boot applique to replace a damaged or worn boot. In Phase I, we will select TCNEBS candidate materials, produce test specimens and evaluate TCNEBS adhesion, sand and rain erosion-resistance and creep-resistance at a recognized test facility. Deicing capability will be demonstrated. The TCNEBS enables unique, in-flight blade flexing not possible with the metal sheath. The Infoscitex team includes experts in z-oriented nanofiber reinforced elastomers, a helicopter manufacturer and an elastomer supplier. BENEFITS: Successful development of the TCNEBS will increase the reliability, survivability and mission lifetime of military rotary wing aircraft, such as the V-22 Osprey, in severe sand, rain and ice environments. The added flexibility of a TCNEBS-equipped composite blade will enable complex twisting and flexing maneuvers in-flight that are not possible with metal protective sheaths. | |

| Title: High Speed RF Waveform Reader-Writer | |
| Abstract: Intelligent Automation, Inc. (IAI), proposes a reliable integrated COTS-based reader/writer that can deliver RF waveforms to a cross-correlation based RF receiver at high speeds of 40 Gbps. We have already identified key COTS hardware that offers following advantages (1) input/ Output blocks of the FPGA can handle various input/ output standards like LVDS, LVCMOS, PCI-X, GTL and GTLP. Hence external COTS hardware delivering any of these voltage formats can be easily integrated (2) Options for reconfigurable logic and signal processing blocks (3) High speed expansion slots, 16 bit TX-RX interfaces with default LVDS support and number of prototyping interfaces, and (4) Low power consumption. The key innovations which we propose are (1) assembly of COTS hardware such as 1: 16 De-serializer and 16:1 Serializer, external memory blocks for data management (2) ability to perform test simulations on the FPGA itself, by creating HDL blocks (3) ability to read 10 Gword/s and store the data using FPGA control and (4) a clear transition plan to output 40 Gbps data per line using 4: 1 Multiplexing. The proposed system can be rapidly deployed for testing within the phase I base period. BENEFITS: The market for a IEEE compliant 40 Gbps per line circuit and accept 10 Gbps per line at data input and rewrite the data in the RAM units is quite large in fiber optic telecommunication network where digital data are be compressed in time and transmitted as bursts rather than time interleaved bit with other traffic. Such networks are also used on military platforms and bursted data may be significantly easier to handle than interleaved in multi-level security and priority networks such as during battle and high speed communication processing. | |

| Title: A Novel Acoustic Pattern Recognition System for Wireless Sensor Networks | |
| Abstract: Wireless Sensor Networks (WSNs) have demonstrated their effectiveness in threat detection and localization. However, there are two critical issues related to signal processing in WSNs. First, energy-efficiency, memory-consumption, bandwidth-utilization, and computation-complexity are of main concern. Second, the application environments contain highly colored noise, multi-path echoes, and simultaneous emission sources. To address these issues, Intelligent Automation, Inc. (IAI) and its subcontractor, the University of Washington, propose a novel acoustic threat recognition system. The proposed system architecture is distributed and hierarchical. The functions of threat detection, classification and source localization are organized in multiple levels. At each level, the information processing task is performed in a distributed manner. On the other hand, the proposed system architecture allows cooperation among sensing nodes to collaboratively detect target signatures, reduce false alarms, classify target types, and estimate the acoustic source location. The system combines recent advances in Wavelet Analysis, intelligent learning and sensor fusion. In particular, the proposed Discrete Wavelet Packet Transform-based power-law detection algorithm is robust to environmental noise, yet computationally efficient. The advantages of the proposed threat recognition system include energy efficiency, reliable detection and classification, low detection and classification latency, reduced false alarms, efficient bandwidth utilization, and accurate source location estimation. BENEFITS: In addition to acoustic threat recognition, the proposed system along with the wireless sensor network architecture can be used in a widely range of other applications, such as moving vehicle tracking, speaker identification, firefighter/military personnel tracking, etc. The resulting technology can be readily used in law enforcement, border protection, etc. Moreover, the proposed classification and data fusion algorithms can also find other applications such as health monitoring of electro-mechanical systems, and intrusion detection in computer networks. | |
