This Phase I project has two primary objectives. The first objective is to develop an engineering model of Resonant Tunneling Devices (RTD) to be implemented in AIM-Spice, a commercial software package running under Windows 95/NT. The development of a reliable device model is a prerequisite for the design and production of any semiconductor device technology. The RTD model will be a semi-empiri ...

This Phase I project has two primary objectives. The first objective is to evaluate the feasibility of a fully ion implanted fabrication process based on the heterodimensional 2-D MESFET. The new device, the 2-D JFET, will have p+ ion implanted sidegates which laterally modulate a thin, highly doped n-type conducting channel. The 2-D JFET should have excellent high speed, low power characteristics ...

The proposed research combines an innovative eigenvector method with other electromagnetic techniques to produce a hybrid approach towards solving the EM coupling to satellite cavity problem. The physical structure is divided into an exterior region and one or more interior regions. The exterior region is modeled with method of moments (MOM) and or hybrids of MOM with the uniform theory of diffr ...

A MODEL FOR PREDICTING THE PERFORMANCE IMPACT OF ENGINE DETERIORATION IS PROPOSED FOR FEASIBILITY EVALUATION. THIS MODEL WOULD ACCOUNT FOR ROTATING COMPONENT DETERIORATION SUCH AS INCREASED TIP CLEARANCES, SURFACE ROUGHNESS, LEADING EDGE BLUNTNESS AND VAN BOW AND TWIST. THE PROPOSED APPROACH USES A STAGE STACKING METHOD TO ALLOCATE LOSSES THROUGHOUT THE ENGINE WHICH ARE DEPENDENT ON OPERATING TIME ...

THE PROPOSED RESEARCH IS DIRECTED TOWARD THE IMPROVEMENT OF THE RELATIONSHIPS USED DURING THE EARLY STAGES OF U.S. NAVY AIRCRAFT CARRIERDESIGN FOR ESTIMATING WEIGHTS, VERTICAL CENTERS OF GRAVITY (KG) AND REQUIRED AREAS AND VOLUMES. THE PRINCIPAL FOCUS WILL BE ON UPDATING THE RELATIONSHIPS USED IN THE NAYSEA AIRCRAFT CARRIER DESIGN-SYNTHESIS MODEL. SPECIFIC OBJECTIVES WILL BE AS FOLLOWS: (A)TO PROV ...

ENHANCED OIL RECOVERY (EOR) BY STEAM INJECTION IS IN WIDESPREAD USE. BETTER DIAGNOSTIC METHODS ARE NEEDED TO IMPROVE THE EFFICIENCY OF THIS EXISTING TECHNOLOGY AND TO DEVELOP NEW TECHNOLOGY. THIS PROJECT CONSISTS OF A DESIGN AND DEVELOPMENT STUDY OF KEY COMPONENTS REQUIRED FOR A DOWNHOLE STEAM QUALITY MEASUREMENT TECHNIQUE. THE MEASUREMENT METHOD, WHICH IS ONE OF THE MOST FREQUENTLY CITED NEEDS, I ...

The Alkali Metal Thermal to Electric Converter (AMTEC) technology is ideal for auxiliary electric power supplies (AEPS) that must operate over a broad range of temperatures, fuel sources, power levels, and operational specifications. The simplicity, efficiency and modularity, as well as the high heat rejection temperature, of this technology allow it fill applications as varied as light-weight ba ...

41084 November 20, 1996 Advanced Modular Power Systems, Inc. The Alkali Metal Thermal to Electric Converter (AMTEC) is a static energy conversion device that operates at thermal to electric conversion efficiencies that have reached 19% and are expected to reach 25% to 30% in mid 1996. These systems operate silently, with no moving parts and can utilize an ...
