Award Data

The ability to efficiently process intelligence data is critical to fighting the global war on terror. A major source of this data is recorded speech. Therefore, the performance of speech processing applications (speech recognition and speaker identification applications, for example) depends on pre-processing to find the regions in the recording where speech is present. Although current method ...

The objective of this effort is to demonstrate a superior prototype diagnostic system and controller for electrical power systems based on AbTech's abductive polynomial network technology. This technology enables designers to semi-automatically model the complex and dynamic behavior of very sophisticated aerospace power systems using models comprised of a network of polynomial equations (abductive ...

CONCERN OVER THE USE OF CHEMICALS THAT POTENTIALLY CONTRIBUTE TO OZONE DEPLETION AND THE GREENHOUSE EFFECT HAS LED TO A BAN ON CHLOROFLUOROCARBONS (CFCS) AND A PHASE-OUT ON THE USE OF METHYL BROMIDE. CFC REPLACEMENT COMPOUNDS, THE HYDROHALOCARBONS, ALSO HAVE EITHER OZONE DEPLETION POTENTIAL OR ARE POSSIBLE GREENHOUSE GASES. PRELIMINARY STUDIES HAVE SHOWN THAT THERE MAY BE A NUMBER OF NATURALLY-O ...

To provide the Airborne Laser (ABL) precision ranging and 3-D track refinement capability for the next generation active ranging system (NGARS), Voxtel will develop an avalanche photodiode (APD) receiver. Unlike the original ARS, which uses a 10.6 µm CO2 laser, Voxtel’s InGaAs-based ARS receiver is designed for high-speed photon counting between 1.0 – 1.6 µm. Operation in the short-wave infr ...

THE PROPOSED PROGRAM WOULD RESULT IN THE DEVELOPMENT OF A PORTABLE FIELD INSTRUMENT FOR THE MEASUREMENT OF AMBIENT AIR TEMPERATURE TO AN ABSOLUTE ACCURACY OF 0.01 DEGREES CENTIGRADE. THE PROPOSED INSTRUMENT WOULD SUBSTANTIALLY IMPROVE OUR ABILITY TO MEASURE AMBIENT AIR TEMPERATURE AND, IN ADDITION, IT WOULD BE ACCURATE ENOUGH SO THAT IT COULD BECOME A STANDARD INSTRUMENT FOR THE CALIBRATION OF FIE ...

The total defense related corrosion costs are estimated at $20 billion of the total annual U.S. cost estimates of greater than $300 billion. Much of the costs are associated with the maintenance of metal materials; 20% of the estimated corrosion-related costs involve scraping and repainting steel structures. Because of the staggering costs stemming from corrosion of steel infrastructure, there i ...

DESCRIPTION (provided by applicant): Millions of children in the U.S. are at risk for learning to read well despite major advances in our understanding of the causes and cures for poor reading. In this Fast- Track proposal we propose to address this significant need and opportunity with a computer-based reading program that combines the power of one-on-one tutoring with the benefits of self-assess ...

This proposal describes a complete vehicle corrosion simulation and modeling tool called ACES (Accelerated Corrosion Expert Simulator) that has a high degree of correlation to actual accelerated corrosion durability test (ACDT) data. The system imports existing 3-D geometric models of full vehicles. An integrity check is conducted to determine if there are missing or improper entities or propertie ...

The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

Nb3Sn superconducting wire is a preferred superconducting medium for certain applications because of the high field it can produce. Nb3Sn-based wire must be reacted at >600 ºC in an inert environment before use, and the wire¿s insulation also must be heated and remain intact throughout this reaction. Because the reacted wire is too brittle to wind, the wire, with its insulation, is first wound ...
