Currently the air beam/arc shelters have no protection from mortar fragmentation or other indirect fire. In many cases, customary methods of ballistic protection such as sandbag walls and/or concrete barriers may require more logistical support than is available leaving the military personal vulnerable to enemy attack. The U.S. Army has evaluated the use of off-the-shelf armor materials and found ...

Under this SBIR program, QuesTek proposes to develop novel thermo-mechanical processing techniques to enhance the bending and contact fatigue resistance of high strength secondary hardening matensitic steels such as Ferrium® C64 for rotorcraft drive train components. A systems-engineering approach will be followed to identify key microstructure attributes (e.g., nonmetallic inclusions) controll ...

School-level curriculum design and instructional delivery is often traditional, not incorporating highly interactive, multimodal social media technologies where users generate content to provide feedback for learners and to support formative assessment. This project team will develop key elements of today’s Web 2.0 social networking technologies to include the potential for collaborative content ...

In recent years there has been considerable public concern about the state of writing – a threshold skill for academic achievement, employment, and participation in today’s world. This project team will create a new technology tool designed to improve student writing performance and the usefulness of writing assessments. U-learn.net will be an online environment that will combine social networ ...

Present thermoelectric devices operate at about 10% of the Carnot efficiency, whereas the efficiency of compressor-based refrigerators is larger than 30%. An increase in the thermoelectric figure of merit ZT above 3 is needed before thermoelectric technology can replace current air conditioning technologies in many applications. Recent models have predicted that ZT can reach 6 in metal/HgCdTe supe ...

The capability to reliably and remotely detect, identify and track biological aerosols is a critical need for the United States military. EPIR Technologies proposes to improve this capability by making use of the infrared signatures from biological aerosol broadband Mie scattering, comprising both mid and long wavelength infrared (MW/LWIR) components, as well as a potential polarization component. ...

The goal of this Phase I proposal is to develop a synthetic, low cost, and benign simulant for biowarfare agents (BWA) to be used in the testing of standoff sensors. Orono Spectral Solutions Inc. (OSS) has performed preliminary work leading to the identification of benign ingredients that, when combined in a predefined mass ratio, mimic UV-Vis and infrared signatures of BG spores. This work was pe ...

The overall goal of this Phase I project is to demonstrate the feasibility of an infrared transparent, micro-fluidic sampling system that will lead to a field-deployable detection system capable of detecting low ppb levels of chemical warfare (CW) agents in water. To accomplish this goal, the proposed detection system will combine high surface area, organically modified mesoporous oxide absorptiv ...

Early detection of positive mild traumatic brain injury (mTBI) status is difficult in the post-trauma period and efficient, noninvasive screening methods are needed. Brain injury from trauma and other neurological conditions frequently escapes detection using current imaging technology such as magnetic resonance (MRI) and computer-assisted tomography (CAT). mTBI is associated with cognitive impa ...

Predicting the violent behavior of energetic materials in accident scenarios is an important issue for the analysis of the performance of explosives and solid rocket propellants. We propose a computational program to predict the shock initiation behavior and subsequent energy release that leads to violent reaction of minimum signature propellants under several impact threat conditions. The modelin ...
