ABSTRACT: The United States Air Force and the Department of Defense are investigating synthesis, scale-up and production of novel energetic materials including high energy density compounds and fuels. Five-membered heterocyclic rings containing nitro groups have demonstrated great potential as energetic materials. Synthetic and engineering challenges are impeding scientists from safely producing ...

ABSTRACT: Availability of high quality, large area gallium nitride (GaN) single crystal substrates is one of the most outstanding issues for III-V nitride materials. Today's GaN device processes typically employ HVPE grown on sapphire and silicon carbide substrates, requiring elaborate buffer layers and deposition techniques to overcome lattice mismatch and dislocation densities up to 109/cm ...

ABSTRACT: The behavior of the Chalcogenide based ion-conducting memristor lends itself for use as an element in a simple neuromorphic computing circuit. The reaction of a circuit to an external stimulus may be the result of its ability to learn from previous similar, yet unrelated exposures to environmental stimulus. A highly specialized variation of the memristor, previously developed by the Ad ...

ABSTRACT: Airborne directed energy weapons offer advantages over conventional weapons as they minimize collateral damage, reducing the cost of post-conflict reconstruction. However, the high power levels required by these weapons present size and weight challenges for airborne applications. In particular, the current capacity required of the power transmission cables can make them one of the heav ...

Thermoelectric generators (TEGs) offer the potential for simple and efficient conversion of heat directly to electricity. However, efficient power conversion systems that incorporate TEGs present an engineering challenge, requiring an overall system design that balances critical trade-offs between TEG performance requirements, thermal management, combustion efficiency, and power conditioning. We ...

A software tool for residual strength and life prediction of advanced hybrid structures will be developed by enhancing and integrating an existing mesh independent 3D X-FEM solid element with a partially bonded cohesive interface element in Abaqus. The tool will be able to model arbitrary location, size of damage, and geometric configuration of fiber metal laminates with the coexistence of metal l ...

ABSTRACT: Primordial, Panoptic, and intuVision propose the development of Tentaclea multi-camera immersive surveillance system that synthesizes information from hundreds of video streams into an intuitive 3D representation. Team Primordial will start with our existing state-of-the-art baseline componentsPanoptic C-Thru, intuVision Panoptes, and intuVision Video Recallwhich already fully meet 6 a ...

ABSTRACT: Airspace congestion with RPAs in close proximity to manned systems poses a serious threat for mishap. At present, RPA pilot training in airspace management is minimal. RPA operator training should consider communications, asset management, deconfliction, and coordination among RPA and manned system pilots, and air battle management personnel. 21st Century Systems, Inc. (21CSI), which h ...

ABSTRACT: Advanced space-borne electro-optical payloads require cooling at temperatures of 10 to 20 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at the primary load site, with additional loads at higher temperatures. During this program, we propose to build and test a multistage hybrid cryocooler that is optimized for cooling at a primary load temperature of 10 to 20 K. ...

ABSTRACT: Creare proposes to design, develop, test, and deliver an ultra-compact star tracker specifically intended for the CubeSat platform. Our design is based on proprietary"folded optics"technology previously developed by our partner for use in military and commercial optical applications that require a compact footprint and high performance. The folded optics design is superior to conventi ...
