The project aims to grow device-quality InxGa1-xN, an important semiconductor because the band gap can be shifted widely by varying x, using a new form of plasma sputtering, Biased-Target Deposition (BTD). The major objectives are to grow x > 0.05 material on sapphire at 600-800°C (standard) and 300-500°C (beneficially reduced) temperatures, and to characterize material quality via X-ray diffra ...

Close Air Support (CAS) is playing an increasing role in military operations. The emphasis on Special Operations in recent years has increased the combat range of small units, often sending squad-sized units hundreds of miles behind enemy lines. Small units rely on stealth and airpower. They remain covert, but when they are discovered, they call in airpower to keep from being outgunned. All too of ...

THIS PROJECT WILL EXAMINE THE PROCESS OF WAVE EROSION OF FROZEN OR PARTIALLY FROZEN SLOPES. THE SPECIFIC APPLICATION IS THE EROSION OF UNPROTECTED CAUSEWAY BERMS BEING CONSTRUCTED IN THE ARCTIC. THE RATE EROSION, THE NEED FOR SLOPE PROTECTION (OR NON-NEED), AND THE TYPE OF SLOPE PROTECTION REQUIRED WILL BE IDENTIFIED. THE TEST WILL BE CONDUCTED AT PROTOTYPE SCALE TO CORRECTLY MODEL THE THERMAL ERO ...

Many modern approaches to autonomy use a layered planning technique where a conventional path planner plans a nominal desired path, and a reactive planner plans trajectories over a local region. In relatively structured environments with good localization, this layered approach has been proven to work well, as shown by TORC’s successful 3rd place entry in the 2007 DARPA Urban Challenge. The ov ...

With the significant advancements in motor efficiency and energy storage technology, electric propulsion systems have become viable power plants and power supplements to aircraft. Offering high power-to-weight ratios, electric drive systems significantly increase the design capabilities for vertical takeoff and landing (VTOL) capable platforms. Ducted fans offer the ability to develop an enclosed ...

A NEW MATHEMATICAL TRANSFORM METHOD FOR THE COMPRESSION OF MOTION VIDEO HAS BEEN FORMULATED BY AVELEX AND A BREADBOARD MODEL FABRICATED TO DEMONSTRATE LOW BIT-RATE MONOCHROME IMAGERY. A METHOD IS PROPOSED FOR OBTAINING COLOR MOTION VIDEO BY A NOVEL MEANS WITH A RATHER SMALL INCREASE IN THE AMOUNT OF DATA REQUIRED TO BE TRANSMITTED. THE BENEFIT OF THIS NEW TECHNOLOGY IS TO PROVIDE STABLE MOTION IMA ...

Azure Summit Technology will develop algorithms and techniques for Vector Navigation (VNAV) in this Phase I effort. Using actual collected GPS signals from a degraded RF environment, we will establish feasibility of VNAV through modeling and simulation. We will also develop a plan for a real time demonstration of VNAV in Phase II, as well as to clearly define the product development and funding ...

SUBSEA OIL AND GAS PRODUCTION SYSTEMS ARE FINDING INCREASING APPLICATION AS THE DEPTHS AND ENVIRONMENTS FROM WHICH PRODUCTION WILL TAKE PLACE BECOME MORE DEMANDING. SOME OF THESE ENVIRONMENTS, SPECIFICALLY THE ARCTIC, WILL NOT PERMIT UTILIZATION OF CONVENTIONAL UNDERWATER INTERVENTION TECHNIQUES OWING TO THE ICE COVER. TO ASSURE SAFE AND POLLUTION-FREE OPERATION OF THESE STRUCTURES WILL REQUIRE DE ...

We plan to develop unique CAD design tools, which facilitate the design of 3D integrated circuits and circuit elements, as well as tools to predict the parasitic effects resulting from 3D integration. These CAD tools will use novel techniques to simultaneously simulate the temperature distribution and heating in a 3D IC and its effect on circuit performance; an efficient impulse response method to ...
