AS THE DOD IS MOVING TOWARDS THE LARGE-SCALE USE OF ARTIFICIAL INTELLIGENCE SYSTEMS FOR SUPPORTING DECISION-MAKING AND INFORMATION ANALYSIS, IT BECOMES INCREASINGLY IMPORTANT THAT WE DEVELOP MECHANISMS FOR ASSESSING THE PERFORMANCE OF THESE SYSTEMS. WE BELIEVE THAT ASKING "HOW INTELLIGENT IS THE SYSTEM?" IS NOT THE CORRECT PERFORMANCE QUESTION AND THAT MORE APPROPRIATE ARE "DOES THE SYSTEM HELP TH ...

THE READY AVAILABILITY OF LOW COST MOBILE ROBOTS (LOCOMOBOT) WOULD PROVIDE RESEARCHERS IN ARTIFICIAL INTELLIGENCE THE TOOL NEEDED TO TEST THESE ALGORITHMS IN A "REAL WORLD" ENVIRONMENT, OUTSIDE OF THE MAINFRAME ON WHICH THEY WERE DEVELOPED. IN OUR PHASE I STUDY, WE WILL ESTABLISH TRADEOFF ANALYSIS FOR THE KEY CHARACTERISTICS OF MOBILITY, FUNCTIONALITY, DATALINK, AND POWER SOURCE. WE WILL THEN REVI ...

THE DEVELOPMENT OF ADVANCED COMPOUND SEMICONDUCTOR MATERIALS FOR THE NEXT GENERATION SEMICONDUCTOR DEVICES WILL INCREASE THE DEMANDS FOR SOPHISTICATED MATERIALS CHARACTERIZATION. ALTHOUGH A VARIETY OF SURFACE AND MICROANALYTICAL TECHNIQUES EXIST FOR CHEMICAL CHARACTERIZATION OF THESE MATERIALS, NO TECHNIQUE YET EXISTS FOR QUANTITATIVE MICROSCALE STOICHIOMETRIC ANALYSES. THE RESEARCH PROPOSED FOR P ...

A POWERFUL APPROACH TO RECHARGEABLE AMBIENT TEMPERATURE ORGANIC LITHIUM BATTERIES OF LIMITED CYCLE LIFE IS PROPOSED WHICH EMPLOYS METAL HALIDES AS REDUCIBLE CATHODES, WHICH WOULD BE DEVELOPED TO REPLACE LI-SO(2) PRIMARY CELLS CURRENTLY SUED BY THE ARMY FOR SMALL UNITS. THIS APPROACH TO HIGH ENERGY BATTERIES IS PARTICULARLY APPROPRIATE FOR SAFE OPERATION AT A HIGH RATE OF DISCHARGE FOR THE DURATION ...

THIS PROJECT WILL SEEK TO DEVELOP NEW METHODOLOGY FOR THE PREPARATION OF CARBON/CARBON (C/C) COMPOSITES. THESE COMPOSITES CAN WITHSTAND USE TEMPERATURES OF 700 DEG F OR HIGHER; IN BRAKING APPLICATIONS TEMPERATURES CAN REACH 1000 DEG F OR MORE WITHOUT FAILURE. CURRENT TECHNIQUES REQUIRE TREATNG CARBON FIBERS WITH GASEOUS HYDROCARBONS AT HIGH PRESSURES AND ELEVATED TEMPERATURES. THE OBJECTIVE METHOD ...

THE LIMITING ELEMENTS IN INDUCTION ACCELERATOR DESIGN ARE DETERMINED BY THE ACCEPTABLE VOLTAGE GRADIENTS ON KEY DESIGN COMPONENTS. WE HAVE ANALYZED THE PROBLEM FOR TYPICAL PARAMETERS (250 KV/STAGE, 10 KA, NS PULSE) AND FIND THAT KEY LIMITATIONS ARE THE FERRITE CORE BULK BREAKDOWN VOLTAGE, FERRITE CORE CAPACITANCE, VACUUM ELECTRODE ELECTRON EMISSION VOLTAGE, VACUUM/DIELECTRIC HIGH VOLTAGE INSULATOR ...

EXISTING CATHODE TECHNOLOGY CANNOT PROVIDE THE COMBINATION OF HIGH AVERAGE CURRENT DENSITY AND LONG LIFE THAT IS ESSENTIAL FOR HIGH AVERAGE POWER ACCELERATOR APPLICATIONS. THESE APPLICATIONS INCLUDE HIGH POWER LASERS, HIGH POWER MICROWAVE GENERATORS, CHARGED PARTICLE BEAM CONCEPTS AND RADIATION PROCESSING. THE CONTROLLED POROSITY DISPENSER (CPD) CATHODE IS A NEW TYPE OF THERMIONIC EMITTER WHICH HA ...
