The video surveillance industry is experiencing dramatic change with the move from analog to digital video. Command centers need to have coordinated viewing of multiple camera feeds at one time, and the ability to switch automatically between feeds and display relevant patterns. Conventional security control rooms include a bank of monitors connected through a switch to an array of security camera ...

In the proposed Phase I program, Composite Technology Development Inc. (CTD) will work with Raytheon Missile Systems to define material requirements for morphing aircraft skins, and will perform material evaluations to demonstrate the feasibility of adaptive materials with dynamically variable stiffness. Georgia Tech Research Corporation (GTRC) will provide mechanical characterization support.

Improved characterization of the dominant paths of bone conducted sound transmission caused by external acoustic excitation for a person wearing a plug/earmuff combination is urgently needed for development of effective hearing protection in extremely high noise fields. This two phase program will achieve this ambitious goal through the extensive use of computer simulation techniques which are su ...

"Energetic thermite composites are composed of a metal fuel (e.g. Al) and an oxidizer (e.g. Fe2O3). Thermite composites have a much higher reaction enthalpy per cm3 than conventional explosives such as TNT. However, current thermite composites do notyield a higher reactive power because of the large diffusion distance between the metal fuel and oxidizer in thermite powders. To minimize the diff ...

The proposed effort can provide the framework for a unified modeling & simulation program to substantially improve the capability for understanding, analyzing, and predicting the underlying mechanisms dictating the combustion stability characteristics of liquid-propellant rocket engines. Emphasis will be placed on the effects of atomization, mixing, and distributed combustion of liquid oxygen (LO ...

Combustion instability in liquid rocket engines (LREs) has manifested in nearly all LRE development programs. While the driving mechanisms of combustion instability are vast and coupled, in all instances, the net result is significant cost and schedule over-runs. In today’s business environment, such over-runs are rarely tolerated and generally result in program cancellations. Development of hig ...

Device structures fabricated in III-V materials such as gallium nitride (GaN)require either deliberately induced defects to take advantage of ultra shortlifetime effects or ideal defect free crystallinity grown at low temperatureto reduce diffusion of hetero-junction interfaces.The essence of the proposed project is to use MBE crystal growth assistancetechniques, such as surfactants or in-situ ext ...

There are no established techniques for determining instantaneous rates of hidden corrosion in aluminum aerospace structures, such as crevice corrosion in an aircraft lap joint or exfoliation corrosion in the midplane of a thick wing plank. Studies showthat SQUIDs are ideally suited for non-destructive analysis of corrosion in specimens where the corrosion activity is not directly accessible to mo ...

The development of optical coatings utilising smart thin film shape memory alloys will be investigated using several techniques. The coatings will be placed on optical quality membranes. Processing conditions to ensure compatibility with the polyimidewill be investigated including the use of both sacrificial layers and conversion coatings to generate the desired heterostructures. In addition, opt ...

This Small Business Technology Transfer Program Phase I objective is twofold. During both depot and field repair operations the coating system is removed using mechanical and chemical stripping methods that result in removal of some of the metallic cladding. The removal of the cladding during paint stripping makes the underlying high strength aluminum alloy more prone to corrosion. Thus, the fi ...
