This Phase I Small Business Technology Transfer program will simulate and demonstrate the feasibility of a Spin-torque microwave diode spectrograph for real-time determination and monitoring of incident microwave signals. The microwave detection will be performed by a bandwidth encompassing parallel array of nano-patterned magnetic tunnel junctions (MTJs). When an ac current of microwave frequency ...

The ability to accurately design and predict the performance of combustion-based machinery like gas turbine engines is important in improving their performance, increasing their fuel economy, lowering operating costs, and decreasing pollutant emissions. Almost all of the flows are turbulent in industrial combustion applications, therefore understanding the interaction between turbulence and combu ...

Vibrant Corporation and Sandia National Laboratories (SNL) propose to apply Process Compensated Resonance Testing (PCRT) to the DLA's need for an NDI method to detect counterfeit, nonconforming and improperly processed materiel. PCRT collects and analyzes the resonance frequencies of a component to detect structural defects, characterize material, analyze population variation, monitor manufacturin ...

Surgical simulations aiming to support surgeon practices and medical education have attracted enormous research effort over the last two decades. However, the physical reality, especially on simulating aggregated tissue interaction, is still unsatisfactory. In this proposed work, an open source surgery simulation framework, SoFMIS, will be utilized and enhanced with tissue interaction models to a ...

This proposal describes a comprehensive effort to develop the required epitaxial materials technologies to support the development and commercialization of next generation, epitaxially grown, engineered III-V LWIR detectors that achieve performance equivalent to much higher cost II-VI detectors. Our team proposes a unique and innovative approach which utilizes MOCVD growth of metamorphic buffer la ...

The intelligence community still cannot satisfactorily answer critical fundamental preparation, planning, and execution questions about the environment in which US and allied forces operate and the people they seek to persuade. There is a vast amount of information, almost all of it unclassified, which characterizes population identities and interrelationships in terms of beliefs, values, interest ...

Modus Operandi and IHMC propose a Runnable Environment for Plug and Scrape (P&S) Technology (REPAST) for plugging in to social networks. REPAST consists of a P&S device enabling soldiers to perform mobile data analysis. The innovative device lets users carry and configure analytic tools as they travel between locations. Users plug the device into an existing computer system and resume a personal c ...

The team proposes a 3D SAR algorithm based on the principles of radar tomography, which allows for transmitters and receivers to be arbitrarily located in a 3D volume. Data is collected and the output is a complete true 3D image of the reflectivity scene. The tomographic SAR provides detailed features on both horizontal (e.g., flat terrain) and vertical (e.g., building or canyons). With a proper ...

A human produces more than 100 Watts of waste heat during normal activity. If a fraction of this heat energy can be harvested it can replace the stored chemical energy in one or more of the batteries typically carried by soldiers in the field. The current generation batteries, such as the BB2590 are bulky and rigid. The PowerFelt material developed by Wake Forest University is ideally suited for h ...

We aim to develop lightweight and rugged liquid crystal (LC)-based sensors suitable for integration into small unmanned vehicles, including hand-launched UAVs and throwable robots. For Phase I proof of concept, we propose to develop sensors that detect DMMP, H2S, NO2 and NH3. These gases include simulants of chemical warfare agents and toxic industrial chemicals, selected for their relevance to ...
