ABSTRACT: The objective of this effort is to develop next-generation architectural and operational concepts, leveraging recent advances in High Performance Computing (HPC) technologies, to improve Wide Area Motion Imagery (WAMI) tracking capacity and performance. WAMI systems typically produce tens of thousands of moving target indicator (MTI) detections from city-sized urban areas at update rat ...

For prediction of hypersonic aerothermodynamics, knowledge of the relevant disturbance levels is required to determine transition locations in flight at the altitudes of interest. Tao Systems and University of Maryland (UMD) propose to develop a flight platform and measurement system capable of acquiring pressure, temperature, density, velocity fluctuations, and particulates using a miniaturized, ...

Space platforms are complex dynamical systems and there are many reasons to model them from ground telescope imagery as well as from space-based sensor platforms. One key motivation is to determine the operational state and configuration of the vehicle. Key questions such as did the solar panels fail to deploy, did the object begin to tumble unexpectedly may be addressed by a sufficiently detaile ...

Project Summary Atrophic dry age related macular degeneration AMD is the leading cause of severe loss of vision for those over age Dietary supplements containing lutein and zeaxanthin are recommended by the NEI for those at risk of late AMD There has been a corresponding growth in demand for these two xanthophylls Lutein and zeaxanthin are currently sourced from marigolds grown mostl ...

DESCRIPTION provided by applicant Advances in DNA sequencing technology have now made it practical and affordable to generate datasets containing millions of genetic attributes that can be tested for association with disease susceptibility The computational complexity of searching for genetic interactions over such high dimensional datasets imposes great challenges for genome wide associatio ...

ABSTRACT: Laser source technology in the mid-infrared region, 2um to beyond 10um, is progressing rapidly. Quantum cascade laser (QCL) is one of these new sources, which cover the whole mid-infrared spectrum with high-power and good wall-plug efficiencies. Due to the micron sized and non-circular cross-section of the active region, the laser beam quickly diverges in the direction perpendicular to t ...

ABSTRACT: Shared Spectrum Company (SSC) partners with Virginia Tech (VT) to develop resilient and agile space communication systems using innovative cognitive radio techniques. The objective of this STTR Phase II project is to develop anti-jamming capability using frequency agility provided by Dynamic Spectrum Access (DSA) technology for satellite communications (SATCOM) systems. The SSC team foc ...

ABSTRACT: Low frequency antennas provide us with the most critical challenge in small UAVs due to the limited available real estate on the platform. The primary objective of our Phase I research was to fill a critical technology gap in small UAVs for low frequency communication and SIGINT applications. We carried out a very comprehensive Phase I research to develop light-weight, conformal volumet ...

ABSTRACT: Vocal communication in the real world often takes place in complex and noisy acoustic environments. For applications such as mobile communications or use of automated speech/speaker recognition algorithms on recorded data, the presence of noise and reverberation significantly degrades the quality and intelligibility of speech and severely hampers the performance of these systems. Approac ...

ABSTRACT: SSC and VT develop algorithms and approaches to manage uncertainty in dynamic spectrum access (DSA) systems for small satellite constellations. We use various DSA rule sets such as sensing, database, and monitoring systems to reduce the uncertainty on a systems level. We investigate uncertainty modeling using Dempster-Schafer theory to build belief, disbelief and ignorance maps of spe ...
