The objective of Phase I is to identify the strengths and weaknesses of the various multi-reference coupled-cluster (MRCC) methods that have been proposed for the description of molecular states depending upon near degeneracies and non-dynamic electron correlation. Such effects are encountered in bond breaking, at transition states, for complex open shell systems like transition metal atoms, and f ...

The ever-decreasing size of the electronic microchips and the ever-increasing density of electronic components required to support future Air Force platforms are creating the problem of substantial localized heat generation that can impair component operation. State of the art thermal interface materials (TIMs), that are used to dissipate heat from the source to the spreader in a microchip, are se ...

The objective of the proposed research is to develop a portable, passive system for rapid and efficient blood component separation. While a number of macro-scale devices are routinely employed in laboratory settings to separate, for example, red blood cells (RBCs) from platelet-rich plasma (PRP), and an emerging class of microfabricated devices are slowly being developed to address various low-th ...

Thermopile arrays manufactured using integrated process compatible materials and micro-machining will provide high performance with low manufacturing cost. Black Forest Engineering (BFE) teamed with Case Western Reserve University will design thermopiles using silicon based semiconductors and compare performance. Low cost thermopiles, differentially coupled with advanced BFE CMOS readout, will pr ...

This Small Business Technology Transfer research project addresses the perception and learning of complex sound patterns within complex auditory scenes. The objective is to model auditory signal processing, pattern recognition and learning in the human auditory system. Our novel approach simulates the nonlinear signal processing that has been observed in auditory physiology. By mimicking functiona ...

ABSTRACT: This proposal is concerned with the development of a novel failure initiation and progressive failure analysis modeling method for advanced composite structures, including the analysis of selected structural joints utilizing a statistically based micromechanics model embedded in a 3D non-linear finite element code. The method accounts for the interaction between out-of-plane failure and ...

The US Army has underscored the importance of developing more effective obscurant material for shielding US soldiers and their equipment from visible, microwave, and infrared observation. Current separation techniques tend to allow the nano-particles to agglomerate at higher density than desired for efficient obscurant devices. ElectroDynamic Applications, Inc. (EDA) in partnership with the Univ ...

The Navy is developing an electromagnetic (EM) launcher for long-range naval surface-fire-support. Severe operating conditions of the EM system place stringent requirements for materials, including high current and magnetic fields, high temperatures, contact with liquid metals, high stress/gouging from balloting contacts and high-speed-sliding electrical-contact with an Al armature. Engineered Coa ...

The proposed research program focuses on design, fabrication, and characterization of quantum-dot infrared photodetectors (QDIPs) which features bias-tunable parameters, including the spectral response, optical gain, and operating time. Wide variations of detector parameters can be realized through the bias-tunable potential barriers surrounding quantum dots. Changes in bias will transform the ba ...

System reliability is a fundamental requirement for safety-critical weapons systems. A key challenge is identifying reliability problems early so that they can be fixed quickly and cheaply. Reliability problems are often integration problems: integration often reveals that flaws that seemed minor in isolated components but lead to serious system-wide reliability problems. The combination of static ...
