ABSTRACT: The K-128 co-processor leverages insights from neuroscience to achieve superior performance. Unlike previous efforts along those lines, our approach is to create a software programmable co-processor that runs existing applications. One of the most salient characteristics of such a co-processor is its power efficiency: not just a few percent more efficient than a traditional processor, b ...

ABSTRACT:For GPS denied navigation, there is a need for developing inertial measurement units (IMU), employing gyroscopes and accelerometers, with better accuracy and/or smaller volume and weight than the state of the art.Under Phase I, we have established the feasibility of realizing a superluminal ring laser gyroscope (SRLG) and a superluminal ring laser accelerometer (SRLA), based on diode-pump ...

In this program, we will develop a breakthrough technology that will enable wafer-scale epitaxial lift-off (ELO) of GaN power device heterostructures from low-dislocation-density bulk GaN substrates. This technology will be used to provide a low-cost vertical junction field effect transistors (VJFETs) with high breakdown voltage (greater than 1,200 V) and high current capability (greater than 100 ...

ABSTRACT: MicroLink and its collaborators, Rochester Institute of Technology and Magnolia Solar, will develop a high-efficiency, single-junction, epitaxial lift-off (ELO) GaAs solar cell by incorporating nano-scale features, such as quantum dots and optically functional textures, within the solar cell structure. The principal technical objective of the project is to increase the AM0 efficiency o ...

ABSTRACT: The Department of Defense requires a reliable non-volatile radiation hardened memory for Space and Airborne platform applications. MGRAM, a form of graphene and magnetic memory, promises to satisfy these requirements and to provide a solution path to achieving low cost, high reliability solid state drives for personal computers and systems. MGRAM is based upon a nano scaled bar magnet w ...

ABSTRACT: CU Aerospace (CUA) and team partner the University of Illinois at Urbana-Champaign (UIUC) propose to perform research, development and demonstration of experimental quenching free measurements of heat-release in a realistic highly turbulent plasma-assisted flame. Kinetics models will be correspondingly updated and detailed 3D multiphysics simulations will be validated by the measuremen ...

CRAFT Tech proposes the development of an innovative design optimization tool called"AeroRCS"which will simultaneously solve for both aerodynamic performance as well as electromagnetic reflectivity (Radar Cross Section). When operated in an automated environment, AeroRCS will intelligently"morph"and steer the shape to converge on an optimal solutions. AeroRCS will be demonstrated by developing ...

Evolving demand for robust and accurate multi-physics modeling tools for high performance combustion devices is being driven by increasingly complex design, analysis, and simulation requirements, but existing models and their underlying assumptions need to be rigorously examined in light of their intended Air Force propulsion system applications. The production use of coupled multi-physics module ...

ABSTRACT: Cavitation which leads to head falloff and feed system instabilities are a constant source of problems for the low net positive suction head (NPSH) pumps that are needed for advanced liquid rocket engines. Head falloff limits the pumps capability to deliver propellant at the required pressure and cavitation induced instabilities are a significant source of structural failures in rocket ...

High Performance Computing technology has advanced significantly, and advanced parallel computers are being built, with DOE leadership. Yet, the American engineering and manufacturing industry has not started leveraging parallel computing at a significant level, partly because of the challenging nature of modern simulation software. US competitiveness in manufacturing may suffer due to its ineffe ...
