ABSTRACT: Many military and aerospace platforms, including a number of airborne and spaceborne vehicles, significantly benefit from new materials that save weight and improve performance. Thermal protection systems (TPS) and extremely high temperature structures are required for a range of hypersonic air and space vehicles. For example, over 20,000 thermal protection ceramic tiles are usually i ...

ABSTRACT: We analyze approaches to adaptively avoid hostile attack to satellite communications by applying a combined approach of game-theory research, dynamic spectrum access (DSA), policy-based resource management controls and wideband sensing. We analyze the impact of game theory to influence adaptive parameters (power, sensing threshold, frequency, network changes) and avoid attack. We study ...

ABSTRACT: PaneraTech,Inc. in collaboration with The Ohio State University ElectroScience Laboratory proposes to develop lightweight,conformal and volumetric UAV antennas based on conductive fibers embroidered on organza and/or polymer dielectric substrates. Given our expertise on designing wideband antennas and weaving them into the UAV for low frequency applications, under this STTR effort, we ...

ABSTRACT: The goal of this effort is to develop a physics-based model and simulation capability for MIMO radar clutter that accurately characterizes the statistical and spectral properties of the clutter under a variety of operating conditions. Our clutter patch model will be capable of predicting field statistical properties including the probability density functions and their parameters (e.g. ...

ABSTRACT: The team of MicroXact, Inc., UCSB and UC Irvine proposes to develop a CMOS-compatible memristor, which will enable next generation signal processors, extremely efficient (i.e. dense, inexpensive, low power consuming), with the capabilities for massively parallel signal processing. More specifically, we offer to solve the reliability and repeatability problem in memristive devices by uti ...

ABSTRACT: The team of MicroXact, Inc., ODU and Virginia Tech proposes to develop a revolutionary high efficiency thermoelectric material fabricated on completely new fabrication principles. The material comprises the three-dimensional"wells"of PbTe/PbSe superlattices fabricated by a conformal coating via Atomic layer Deposition (ALD) of macroporous silicon substrates. Such a material will provide ...

To support large scale Fiber Optic (FO) network deployment, there is an identified industry need for a low cost, optical network reflectometer with high resolution and much lower cost to be used in the maintenance of FO networks. This technology supports new FO networks that are being installed in neighborhoods, office buildings, fibertothehome, local area networks, small office/home office (SOHO ...

Since the Fukushima accident, the DOE, nuclear fuel suppliers, and EPRI, have begun to focus R & amp;D efforts on advanced LWR fuel and components that are more accident tolerant than current zirconium alloys. One area of interest are fuels and components fabricated from ceramic composites that do not balloon during LOCA accidents, do not react exothermically with water during post LOCA quench, an ...

The development of high-current, short-duration pulses of electrons has been a challenging problem for many years. High current pulses are widely used in injector systems for electron accelerators, both for industrial linacs as well as high-energy accelerators for linear colliders. Short-duration pulses are also used for microwave generation in klystrons and related devices, for injectors to perfo ...

This project will provide a low-cost route for high-yield fumarate production from pretreated non-food cellulosic biomass mediated by recombinant cellulolytic Bacillus subtilis. The cellulose fraction of biomass feedstock contains more than one half oxygen by weight, making it a good starting material for the production of oxygen-containing polymeric monomers. Fumaric acid or fumarate, among the D ...
