A nearly universal trend in modern technology is integrating systems, and their associated devices, on decreasingly smaller scales. Examples range from complete telecommunication systems on a chip to implantable medical devices smaller than human cells. The majority of these devices apply hybrid designs that integrate on a commensurate scale electronics with active and passive optical components. ...

Predicting the radio signal levels and coverage areas for Information Warfare System communication channels between base stations, vehicles and warfighters is a challenging problem. The channel may involve radio frequency interactions with hills, foliage, and buildings. The paths may involve long distances over hilly terrain or shorter distances involving interaction with urban building features ...

We propose to build an Open Analytical Framework using a technology called Cluster Based Repositories to support collaborative, distributed data collection and analysis. The Open Analytical Framework will be an inexpensive, distributed information analysis platform. It emphasizes collaboration through information liquidity and performance through massive scale and parallelization. It is compose ...

The Lightweight Beam Director Phase II effort will develop a beam director and beam control concept for use in DARPA programs. Brashear LP will incorporate advanced, lightweight mirror designs, innovative design approaches, advanced/lightweight materials and new control systems approaches as necessary to develop a beam director concept suitable for use with the DARPA lasers under development.

A major drive in medical research today is the search for genes and other biological markers that can indicate a biological agent, an illness, or susceptibility to disease. In research labs, large amounts of resources are devoted to this task. Vast amounts of data are generated in studies; one of the greatest challenges faced by these labs is the task of properly analyzing the data at a rate tha ...

The principal objective of this Phase II proposal is the development and subsequent commercialization of a low-cost hydrogen purifier designed to be an integral component of a fuel reformer in a proton exchange membrane fuel cell (PEMFC). Power and Energy (P&E) brings to this task a 10 year record of production and sale of more than 1000 commercial hydrogen purifiers in which hydrogen is diff ...

WE PROPOSE AN EFFICIENT AND COST-EFFECTIVE QUERY PROCESSING COMPONENT FOR AN INFORMATION RETRIEVAL SYSTEM BASED ON THE USE OF NETWORKED MICROCOMPUTERS AS A LOOSELY-COUPLED NETWORK DATABASE. THE QUERY PROCESSSING SYSTEM WILL WORK ON BOTH LOCAL AND WIDE AREA NETWORKS AND CAN BE USED WITH ANY METHOD OF INFORMATION RETRIEVAL. WE PROPOSE TO: 1. MODEL THE EXPECTED PERFORMANCE OF THIS SYSTEM SO THAT IT M ...

SYSTEM LEVEL DESIGN DECISIONS ARE KEY TO MULTI-COMPONENT SYNTHESIS: THE DETERMINATION OF WHERE TO SPLIT THE FUNCTIONALITY AMONG COMPONENTS HAS A GREAT EFFECT ON THE SIZE AND PERFORMANCE OF THE DESIGN. BY PARTITIONING A BEHAVIOR ONTO SEPARATE MODULES EARLY IN THE DESIGN PROCESS, THE PHYSICAL IMPLICATIONS CAN BE PROPAGATED TO LATER DESIGN STAGES. DASYS PROPOSES TO DEVELOP A TOOL TO AID IN THE DESIGN ...

LARGE, HIGH QUALITY CDZNTE SINGLE CRYSTALS AREREQUIRED AS HGCDTE EPITAXIAL SUBSTRATES IN THE MANUFACTURE OF INFRARED FOCAL PLANE ARRAYS. BRIDGMAN GROWTH PROCESSES ARE CURRENTLY EMPLOYED TO PRODUCE MATERIALS WHICH MEET SOME APPLICATION REQUIREMENTS, BUT FALL SHORT IN MANY STATE-OF-THE-ART EPITAXIAL HGCDTE DEVICES. BRIDGMANTECHNIQUES, BEING MELT PROCESSES, ARE STRONGLY INFLUENCED BY INTRICATE COUPLI ...

CERAMICS HAVE BEEN SHOWN TO BE VERY EFFECTIVE IN THE DEFEAT OF A WIDE RANGE OF KINETIC ENERGY (KE) THREATS. HOWEVER, THE USE OF CERAMICS IN ARMORED VEHICLES HAS BEEN LIMITED DUE IN MOST PART TO THEIR HIGH COST. CERAMIC PARTICULATE REINFORCED METAL MATRIX COMPOSITES (MMCS) PRODUCED BY PRESSURELESS LIQUID METAL INFILTRATION ARE INEXPENSIVE RELATIVE TO MONOLITHIC CERAMICS DUE TO THE LOWER COST OF THE ...
