ABSTRACT: Speech recognition technology is in wide use today and has been successfully integrated in a number of applications. Most of these applications require a microphone located near the talker. However, when a distant microphone is used where the speaker is at some distance from the microphone as in a hands-free communication, or in a meeting room, there is a major problem with the captured ...

ABSTRACT: The hydrocarbon-fueled scramjet is capable of providing hypersonic air-breathing propulsion for high-speed applications. The effective operation of high-speed air-breathing engines (ram- and scram-jets) over a wide range of flow parameters (velocity and altitude) is one of the most technically difficult challenges in the design of hypersonic vehicles. The most promising approach to overc ...

ABSTRACT: The need for improved performance of liquid rocket engines requires efficient wall cooling technologies to mitigate high heat fluxes from hot combustion gases to the engine wall in the thrust chamber. High heat fluxes to the chamber liners can be overcome by fuel film cooling (FFC) of the inside chamber using the liquid propellant. Moreover, the thermal cracking of the fuel creates coke ...

ABSTRACT: Enig Associates, Inc., a small business providing advanced modeling and simulation capabilities to the DoD and DoE, is proposing an innovative and novel electrical approach, using explosive-driven flux compression generators (FCG) to convert explosive chemical energy to electromagnetic energy with very high current output and superb energy conversion efficiency and then Joule heat light ...

ABSTRACT: The next-generation Global Positioning System (GPS) in congested and contested environments is expected to exploit Spectrum Holes (SH) in order to provide uninterrupted Position Navigation and Timing (PNT) service worldwide. Innoflight has teamed with the Air Force Institute of Technologys (AFITs) Autonomy and Navigation Technology (ANT) Center to develop a system based on cognitive radi ...

ABSTRACT: The sensor system requirements for image based navigation that uses passive millimeter wave imaging radiometry will be established based on existing RelNav and AbsNav algorithms that were demonstrated to work in multi-modal imagery. Existing flight data will be used to simulate the PMMW imagery for these tests. A preliminary design of such a PMMW system will be created. Under Phase-II th ...

ABSTRACT: FIRST RF has teamed with University Research Foundation (URF) and Radiometrics Corporation to develop a passive radiometer-based geolocation system for use with a wide variety of USAF platforms. The system will be comprised of a ruggedized, near-COTS radiometer system by Radiometrics Corporation, augmented with a robust 2-D scanning beamsteering antenna by FIRST RF Corporation and enhanc ...

ABSTRACT: Our main objective in this project is to propose a novel Structured Sparse Priors for Target Recognition (SSPTR) system and to demonstrate that discriminative applications such as data clustering or target detection, tracking, and classification can be solved effectively and directly on the compressed measurement domain without the need to recover the original data. Our proposed sparse-r ...

ABSTRACT: Future corrosion and wear protection of structural metals on on military aircraft and weapon systems will require advanced development of metallic and composite materials that are not restricted with respect to environment, safety and occupational health regulations. Conventional metallic alloys containing chromium, nickel, cobalt, and tungsten that have historically provided coating pro ...

ABSTRACT: Wireless communications, radar, and biological detection require electronic components operating in the mm-wave and THz frequency ranges. GaAs metal semiconductor field effect transistor and nanoscale CMOS technologies have demonstrated high frequency capabilities and will likely benefit from future material systems and device architectures. The cost of exploring this wide design space c ...
