Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

DESCRIPTION (provided by applicant): Pretest probability assessment (PTP) plays a pivotal role in the evaluation of pulmonary embolism (PE) in the emergency department (ED) and accurate PTP assessment can modify defensive test-ordering behavior by physicians. However, current methods of PTP assessment produce broad categories of risk that tend to over fit individual patients and seldom obviate tes ...

DESCRIPTION (provided by applicant): The Genomics Revolution and the resultant explosion of knowledge in genomics are shaping our futures. Therefore, it is crucial that knowledge of genomics is broadly disseminated, so that future scientists, educators, policy makers, community leaders, and heads of households can harness the beneficial power of genomic science. Given the indiscriminate impact of ...

Our Phase II goal is to develop (model, design, fabricate and test) a miniaturized biofuel cell capable of generating energy from biomass to power the OFW sensor suite. Phase I goals were successfully met by demonstrating a prototype using glucose as fuel. In contrast to conventional technologies, this biobattery promises to be compact/lightweight, require little/no logistical support (re-supply ...

Power generation, power distribution and electric propulsion on ships and aerospace vehicles could be made smaller, lighter, more efficient, more versatile, and lower maintenance by operating these systems—partly or entirely—at cryogenic temperatures. Our goal is to demonstrate the advantages of cryogenic operation in regard to electronic components, specifically semiconductor devices (power d ...

Teh objective of the proposed work is to develop a process for the fabrication large-area aluminum nitride (AlN) wafers of up to 2" in diameter for III-nitride substrate applications. The growth process is based on a sublimation technique that utilizes adequately prepared SiC wafers as large-area seeds. A multi-step process developed in Phase I will be upscaled to larger area deposition, and will ...

This proposal is for the design and development of a challenging, adaptable, and extendible AI system for use in state-of-the-art computer-based wargames. The development will result in a 3rd generation computer wargame based on modern air power conflict and the ability to apply the technology developed for this project in other wargames ranging from tactical ground-based warfare to naval conflic ...

Ultra-high performance multi-function RF electronics are required by the United States Department of Defense to enable next generation radar and sensor networks in response to an increasingly diverse array of threats to our military and our homeland. An elegant potential solution is that of gallium nitride (GaN) RF electronics, which has shown great promise on currently available yet foreign subs ...

The Phase II STTR will demonstrate the device operation of a GaN Schottky diode power rectifier. Kyma Technologies, Inc. will collaborate with investigators at Auburn University and North Carolina State University for materials growth/characterization and device fabrication/testing. The fabrication of a conventional Schottky diode relies on heteroepitaxy on lattice- and thermal-mismatched foreig ...

Development of an Optimal Bioaerosol Sampler with enhanced optical triggering capability is proposed, following a highly successful Phase I effort that clearly demonstrated feasibility. The threat of a bioaerosol attack can be partially mitigated by deployment of a cost-effective sensor network. High priority programs, such as BioWatch and Portal Shield will benefit from a sensor compliant to Join ...
