ABSTRACT: This Phase II proposal seeks to develop a prototype speech segregation system that can significantly improve intelligibility of noisy speech for human listeners, a technical challenge that has eluded a solution for decades. Motivated by principles of auditory perception, system development is based on an auditory scene analysis approach to speech segregation. This approach differs subst ...

Multi-processor computing systems are growing in capacity and usage. They encompass multiple, distributed implementations as well as heterogeneous, embedded computing architectures. The processing density enabled by such approaches holds promise for unmanned combat air vehicles (UCAVs) with their plethora of mission sensors and command and control processing requirements. However, the software ...

ABSTRACT: Thermal interface materials (TIMs) constitute an essential part of thermal management which is quickly becoming the limiting factor in high power, high functional density, and increasingly small-sized electronics for future U.S. Air Force (AF) platforms. Examples of critical applications of interest to the AF include that require improved thermal management include modern aircraft, dire ...

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 ...

As the computer industry moves toward multi-core, many-core and Graphical Processing Unit (GPU)-based architectures, traditional serial software can no longer make optimal use of a computer"s processing power. Instead, applications now need to be parallelized to take full advantage of modern multi-core CPUs and accelerators such as GPUs. However, developing parallel applications is not an easy ta ...

ABSTRACT: A Novel Superconducting Magnetic Energy Storage (SMES) system is proposed. The Tai-Yang Research Company (TYRC) of Tallahassee, FL in collaboration with the Center for Advanced Power Systems (CAPS) also of Tallahassee, FL proposes in Phase 1 to design a prototype SMES system with significantly enhanced energy storage capacity over earlier SMES concepts. With this design the potential ex ...

ABSTRACT: We will design, fabricate and test a quantum processing unit (QPU) based on a symmetric ion trap chip. The trap will provide trapping depth similar to that obtain with macrosize Paul traps. In addition to the ion trap, this chip will incorporate integrated optical systems which will deliver the light fields required by the elementary quantum processing unit (or quantum sensing unit). ...

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 ...

ABSTRACT: The Air Force has needs for compact, light weight and efficient energy storage devices that do not experience significant performance degradation after many operating cycles. We propose to develop a superconducting magnetic energy storage device (SMES) that is constructed from high-temperature superconducting helical REBCO coated conductor cables. The high charge and discharge powers re ...

ABSTRACT: Chiaro Technologies and the University of Colorado will prove the feasibility and investigate the capabilites, limitations, and extensions of the HOlographic Range-doppler processor for Ubiquitous radar Systems (HORUS) in this Phase II STTR. HORUS encodes the signals from a 1-dimensional RF antenna array onto the broad optical bandwidth of a femtosecond comb laser as pulse compre ...
