In response to the need, in forward areas, of assessing the likelihood of a mTBI having occurred, the objective of this project is the development of the CBIAS computerized assessment system that will be able to make this determination on the basis of the functioning of the II, III, IV, VI, and VIII cranial nerves. They provide the opportunity to obtain a sensitive and quantitative evaluation of t ...

US forces are increasingly involved in asymmetric warfare, peacekeeping and humanitarian assistance missions. These scenarios can place soldiers in direct contact with harmful biological and chemical warfare organisms and agents, toxic industrial chemicals, and explosives. Current portable sensor technology solutions rely on visible and near-IR Raman or fluorescence spectroscopy. A portable sen ...

The overall objective of this program is to enable low-cost production of high performance visible, IR and bispectral obscurants for improved ground force stealth and protection across the Armed Forces. In order to realize this goal, NanoSonic and Virginia Tech will build on promising Phase I results to investigate synthetic and processing approaches, optimize materials synthesis and processing, ...

ABSTRACT: Aurora and UCLA"s Phase I efforts demonstrated the feasibility of the synthesis of advanced hybrid materials, unitized structure, and metallic-composite bonding on the Air Force Next Generation Transport. The X-55 Advanced Composite Cargo Aircraft (ACCA) wing was used to demonstrate the damage tolerance of Glass-Reinforced Aluminum Laminate (GLARE), which is an advanced hybrid material ...

ABSTRACT: High frequency combustion instabilities in gas turbine thrust augmentors (called screech) are detrimental to performance and limit operational flexibility, but are unavoidable due to the nature of augmentor operation and design. Present approaches to screech suppression via passive control provide acoustic damping over limited bandwidth, while active control methods are impractical for ...

ABSTRACT: Lightweight silicon-based ceramics are leading candidates to replace heavier nickel-based superalloys for use on hot section components in next generation gas turbine engines having increased specific power. However, exposures of these materials to the high temperatures, pressures and velocities of water vapor containing combustion environments alter the effectiveness of thermally grow ...

ABSTRACT: Providing electrical power for long duration hypersonic flight is a technology that is required to bring about this revolutionary mode of transport. Whether for weapons delivery or for space access, the long duration missions anticipated require a novel approach to the generation of electrical power during flight. Scramjets contain no rotating shafts from which typical generators or mec ...

ABSTRACT: The team of MicroXact, Inc., UCLA, UC Irvine and Carnegie Mellon University proposes to engineer revolutionary nonvolatile reconfigurable plasmonic gates for information processing on the basis of ultrafast plasmon-enhanced all-optical magnetization switching. This unique approach allows one to program any gate between several different states at very high modulation rates and low power ...

Improved understanding of mechanisms controlling bone conduction (BC) sound transmission, especially with respect to acoustic excitation, is urgently needed in order to develop more effective hearing protection in extremely high noise fields. The Phase I research program made great progress toward this goal by yielding new insights into a mechanism believed to be a significant contributor to BC s ...

The objective of this STTR Phase II proposal is to build a versatile, near-surface light weight multifunctional metallic structure that can be used for magnetohydrodynamic (MHD) control and power generation. In order to achieve these goals, a controlled plasma must be generated in air with high efficiency, the air must pass through a strong magnetic field, and current must be able to flow through ...
