Detection of chemical and biological warfare agents in a real-world setting is an increasingly urgent problem. Many of the current state-of-the-art sensors are aqueous based and require large biomolecules, such as antibodies, to achieve binding of the target molecule and subsequent reporting of the binding event. These technical hurdles are a drawback when considering deployment of these technol ...

An approach for performing high fidelity modeling for blast and progressive collapse simulations of buildings will be developed. The modeling approach will allow complete simulations of building response to be performed within several days of computing time on desktop PCs. An 'easy to use' modeling interface will also be demonstrated in this effort. All response regimes will be addressed includi ...

Alameda Applied Sciences Corp proposes to develop a fast pulse, directed, fast neutron source to detect special nuclear materials at large stand off. Our source offers a

Until now gamma radiation detection has required large single crystals of sensitive materials that are difficult to produce consistently on an industrial scale. In collaboration with a research group at the University of Texas at Arlington, Agiltron proposes to develop a new class of nanocomposite scintillator materials. The radiation detection characteristics of the synthetic nanoparticles in the ...

A new type of compact induction accelerator currently under development at the Lawrence Livermore National Laboratory (LLNL) promises to increase the average accelerating gradient by at least an order of magnitude over that of existing induction machines. The machine is based on the use of high gradient vacuum insulators and advanced dielectric materials and switches. The system, called the Diel ...

For ultra high speed applications in DoD satellite systems, devices and circuits fabricated from III–V semiconductor compounds offer significant advantages over silicon-based technology in terms of operating speed and power. However, the uncertainty in single-event-effect (SEE) response of compound technologies forces the use of empirically-based hardening techniques with penalties in increased ...

Current high energy, multi-room test facilities operated in support of Defense Threat Reduction Agency (DTRA) efforts suffer from a lack of robust sensors that can provide a cost-effective approach to obtaining dynamic-pressure induced gas flow data during internal detonations events. Exquadrum, Inc proposes a new sensor package that utilizes existing piezoelectric sensor technologies, but incorp ...

We propose a radically new approach to gamma scintillator materials based on high-Z polymer composites. These composites contain two key components molecularly dissolved in a polymer matrix that serves as the binder: (1) high-Z compounds for stopping high-energy gamma radiation; (2) luminescent conjugated polymers that functions as the scintillation activator. The molecular-level dissolution ensur ...

This proposal addresses the NGA SBIR program objective to develop and demonstrate GPS receiver improvements for ground users to provide significant “high-sensitivity” signal tracking performance over conventional military GPS receivers. The proposed system consists of (i) the Mayflower “NavAssure” SAASM GPS receiver; and (ii) receiver software signal processing enhancements, in order to m ...

Many military users need to operate in areas where GPS signal reception is impeded by building walls, dense foliage and urban canyon. Current military GPS receivers do not operate robustly in these environments which include multipath and varying signal levels caused by partial blockage/non-penetration of signals through different materials. Some vendors in the commercial sector, however, have b ...
