The project will demonstrate a multi-GHz thin-film transistor with multi-micron feature sizes. The inherently defect-tolerant character of the indium arsenide-based materials system supports high mobilities in defect-rich, polycrystalline epitaxial layers. Circuits using the TFTs will eventually be deployable on flexible/conformal substrates extensible to multi-meter^2 and roll-to-roll substrates. ...

This Phase II effort demonstrates the feasibility of integrating a chemically powered or “active” infrared (IR) treatment into an inflatable device and then perform three experimental excursions with the hardware: 1) achieve a tunable IR signature by cooling the surface; 2) achieve tunable IR emissions combined with a predetermined and fixed radar cross section (RCS); and 3) achieve both varia ...

The goal of this Phase II research is to synergistically combine the novel Electrical Resistance Change Method (ERCM), the guided wave inspection method, and the robust processing algorithms for nondestructive evaluation and inspection of composite structures. The ERCM has key advantages such as low cost, no strength reduction, the capability to detect and locate delaminations and cracks, no need ...

In this proposal, we identify QoS metrics based on our insights on heavy-tailed phenomena in ad hoc wireless networks, determine the potential performance impact of heavy-tailedness on ad hoc routing, define routing policies based on such insights and metrics, and propose a QoS Routing protocol (HAQR) that captures the heavy-tailed nature and provides quality of service for multi-hop wireless ad h ...

There are many factors that render automatic target recognition challenging. These include cluttered background, adverse weather and acquisition conditions, spatially closed targets, spectrally-matched decoys, and the limits on sensor resolution etc. One solution is to have a 3D display, which will help discriminate the targets. However, a major challenge in rectifying the sensor streams, i.e. to ...

The goal of the proposed research is to develop a highly sensitive, high-throughput, and miniaturized assay system for rapid detection of brain injury-specific biomarkers in serum. The assay will be integrated into a portable detector so results can be immediately communicated to the health-care provider for assessment and appropriate treatment of patient injury. This technology will be particul ...

Modern munitions need the ability to track moving targets with passive sensors. This requires a 3D reconstruction of both the background scene and moving objects. Normally this is done with stereo vision to generate a 3-D scene. Unfortunately, the use of paired cameras on munitions is difficult due to the need for spatial separation of the cameras for resolution and the general desire to minimi ...

Significant recent research has shown that breath biomarkers are excellent indicators of oxidative stress caused by conditions ranging from radiation exposure to COPD. Current techniques for collection, concentration, and analysis of exhaled breath do not support real-time analysis, or require complex and bulky equipment. Streamline Automation, LLC will develop a portable Breath BioDetector in p ...

The Air Force wants to develop strain sensors that can be installed inside rotating machinery to wirelessly transmit high speed, high resolution strain data to a stationary receiving system. The goal is 100 sensors transmitting 45 kHz strain data with 1 Hz resolution from within the first three stages of a jet turbine engine's compressor. Our Team believes that a combination of microwave technique ...

Gel propulsion systems combine the best characteristics of solid and liquid propellants. The gel system stores like solid propellant, but flows like a liquid when pressurized, enabling throttle and restart capability similar to liquid propellants. An enabling technology for the further advancement of gelled propulsion is the development of tools to render the development of propellant formulation ...
