We propose to develop an intelligent assistant that enables the rapid creation and use of web services for the warfighter. We will design a web services toolbox, and a web-based assistant built on it, that extends public-domain interoperability technologies with capabilities for dynamic web service creation, tagging services and their history with semantic metadata, and browsing and invoking web s ...

FPGAs have attracted a great deal of attention over the past decade because of their performance, scalability, and cost relative to traditional hardware platforms. However, one of the most significant disadvantages of FPGAs is based on the underlying architecture on which they are built. Specifically, routing delay through the chip is one of the largest bottlenecks in developing FPGA-based appli ...

Based on multiple technology platforms, innovative nanomaterials with much improved magnetodielectric properties have been developed in the Phase I program. Following Edison’s model of product and process development for technology innovations, Phase-II will pursue further incremental improvement in material properties upon the concept-proving material platforms to achieve high and matched die ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

INCREASES IN SOLAR CELL EFFICIENCY CAN BE ACHIEVED WITH TANDEM MULTI-JUNCTION STRUCTURES TO IMPROVE THE PERFORMANCE AND SCALE OF SPACE PHOTOVOLTAIC CONCENTRATORS. THE "TOP SOLAR CELL" TANDEM APPROACH COULD INCREASE ENERGY CONVERSION EFFICIENCY BY AS MUCH AS 100%. A SELF-SUPPORTING ALUMINUM-GALLIUM-ARSENIDE (ALGAAS) TOP SOLAR CELL IS BEING DEVELOPED FOR MECHANICAL ATTACHMENT TO A SILICON CONCENTRAT ...

EXISTING METALLIC-TYPE CONTACTS ON GALLIUM ARSENIDE (GAAS) HAVE NOT BEEN STABLE AT HIGH TEMPERATURES BECAUSE OF INTERDIFFUSION AND/OR ALLOYING OF THE GAAS TOP LAYER. HIGH TEMPERATURE CONTACTS TO GAAS SPACE PHOTOLTAIC CELLS ARE BEING DEVELOPED BASED ON THE FORMATION OF A HIGHLY-STABLE INTERMEDIATE DEGENERATE SEMICONDUCTOR LAYER BETWEEN THE GAAS AND A HIGH TEMPERATURE METAL ALLOY. THE INTERMEDIATE S ...

UNIFORM LARGE AREA, DEVICE QUALITY INDIUM PHOSPHIDE (INP) EPITAXIAL LAYERS ON INSULATING SUBSTRATES COULD LEAD TO THE DEVELOPMENT OF A NEW GENERATION OF PRODUCIBLE, RADIATION-HARDENED MICROELECTRONIC AND OPTOELECTRONIV INTEGRATED CIRCUITS. INP ALLOYS OFFER THE ADVANTAGES OF: PROVEN RESISTANCE TO RADIATION DAMAGE; LOWER SURFACE RECOMBINATION THAN GAAS; HIGH PEAK ELECTRON VELOCITY; AND BANDGAPS THAT ...

HIGH TEMPERATURE (>600 DEGREES CELSIUS) INDIUM PHOSPHIDE (INP) SPACE SOLAR CELLS ARE BEING DEVELOPED TO ELIMINATE THEPROBLEMS, SURFACE DECOMPOSITION AND CONTACT FAILURE, ENCOUNTERED WHEN INP SOLAR CELLS ARE EXPOSED TO HIGH TEMPERATURES. KEY TO THIS PROGRAM ARE THE USE OF AN ENCAPSULANT LAYER TO ARREST SURFACE DECOMPOSITION AND A HIGHLY-STABLE INTERMEDIATE DEGENERATE SEMICONDUCTOR CONTACT SYSTEM DE ...
