Fuel cells bring about the direct conversion of stored chemical energy to electrical energy having efficiencies much higher than those of Carnot engines. So far, the proton exchange membrane (PEM) fuel cell system is the leading candidate fuel cell power source for many military and commercial applications. In order to make PEM fuel cell power sources cost-competitive with competing technologie ...

We propose to develop a versatile comprehensive design system for designing printed-circuit antennas and arrays. To provide an all-encompassing design environment, the design system will provide capabilities to perform array synthesis, simulate aperture-coupled as well as proximity-coupled stacked elements in a multi-layer configuration, design the feed network, and perform accurate array analysi ...

The principle objective of the proposed research program is the development of a noval spatial light modulator that calculates a 3 x 3 kernel convolution on an input image. The spatial light modulator consists of a ferroelectric liquid crystal modulator on top of a CMOS VLSI chip. During Phase I, a comprehensive study of several convolving SLM designs will be performed. The study will examine circ ...

Current radiator design technology has proven ineffective and inefficient for high performance combat vehicles with smaller silhouettes. Goss Engineers, Inc. proposes a new and innovative modeling approach to determine the Army's future direction in radiator designs. We will develop Computational Fluid Dynamics (CFD), Heat Transfer and Thermal Stress models to examine the significance of several ...

This proposal responds to the DOD requirement for a dendrimer-based coating to protect materials from chemical agent contamination and degradation due to environmental and POL (petroleum, oil, lubricant) exposure. The benefits of such protection include enhanced reliability, improved safety, reduced maintenance costs, and extended service life. The development of a low energy coating based on th ...

Semiconductor-catalyzed photooxidation of chemical waste is a comparatively recent development which offers several advantages over other know oxidation processes. The advantages include: 9i) no consumption of expensive oxidant; (ii) catalyst is non- hazardous; (iii) the photocatalytic reactions may be driven by sunlight, and (iv) the oxidation is powerful and leads to the mineralization of the m ...
