This project will investigate candidate space-time coding schemes to be incorporated in a multiple-input multiple output two-way communication system that operates within an urban warfare environment. The main objective is to increase channel capacity to achieve high-quality video transmission using narrow signal bandwidths, typically deployed for voice channels. The investigation will determine t ...

Advanced Cooling Technologies, Inc. (ACT), in partnership with the University of Nevada-Reno (UNR), is developing a high performance metal hydride heat storage and dissipation technology for high power lasers. The proposed technology incorporates heat pipes for passive acquisition and dissipation of high heat flux heat loads and metal hydrides for storage of the heat loads during the laser operati ...

Boron has significant potential as a high energy density fuel in munitions and propellants. Its superior energy density makes it attractive as a fuel component in conventional solid propellants, as well as fuel slurries for ramjet applications. For a ramjet ducted rocket, theoretical density impulses of 1600-1800 sec-g/cm3 have been reported, 45% higher than the best hydrocarbon formulation. Bo ...

ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...

ABSTRACT: The proposed VPHS (Vision Processor for Helmet Systems) is an advanced technology image processing engine that is designed to provide the image processing requirements of helmet mounted imagery systems. The VPHS will input high resolution image data from imaging sensors, process that data to yield enhanced visualization and output the imagery to operator displays. The VPHS will employ im ...

ABSTRACT: Remarkable advances in artificial intelligence (AI) and human-systems integration are providing aircrew with cockpit automation systems of unprecedented sophistication. Onboard intelligent assistants monitor the aircraft, interpret and carry out pilot commands, and advise the pilot (onboard or remote) as to aircraft and system status, mission progress, threats and alerts. Because pilots ...

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: Methodology for prediction of soot build-up in liquid film-cooled rocket engines will be incorporated into the CRUNCH CFD code, using a reduced-mechanism pyrolysis model and soot formation model developed at University of Virginia. A companion experimental program will be conducted at University of Virginia to collect data for calibration of the pyrolysis models for conditions and fuels ...
