SOLID BORON HAS LONG BEEN RECOGNIZED AS A POTENTIAL HIGH VOLUMETRIC DENSITY PROPELLANT FOR VOLUME LIMITED ROCKET AND AIR BREATHING PROPULSION SYSTEMS. HOWEVER, ACHIEVING THIS POTENTIAL HAS BEEN DIFFICULT DUE TO LOW COMBUSTION AND HEAT RELEASE EFFICIENCIES IN CONVENTIONALLY DESIGNED COMBUSTORS. A THREE PHASE MODEL OF BORON ASSISTED COMBUSTION IS POSTULATED AND THE ROLE THAT KINETIC SENSITIVITY ANAL ...

SPACE-BASED FACILITIES FACE AN UNEXPECTEDLY HOSTILE ENVIRONMENT AT ORBITAL ALTITUDES DUE TO CHEMICAL INTERACTIONS WITH ATOMIC OXYGEN AT THE HIGH VELOCITIES OF ORBITING SPACECRAFT. DEGRADATION AND EROSION OF MATERIALS FACING INTO THE ATMOSPHERIC WIND POSE A THREAT TO THE EFFECTIVE LIFE AND UTILITY OF SATELLITES, SPACE STATION SYSTEMS, AND EXPECIALLY SPACE-BASED OPTICAL INSTRUMENTATION. WE PROPOSE T ...

THIS PROJECT WILL DEFINE A COMPUTER SIMULATION CAPABILITY THAT CAN SYNTHESIZE CLOUD CLUTTER AND SEA RADIANCE SCENES MEASURED BY SHIPBORNE IRST SENSORS. THE CAPABILITY WILL BE AN EXPANSION OF ARI'S EXISTING AERIE (AERODYNE INFRARED EARTH) IR BACKGROUND RADIANCE SIMULATION CODE, DEVELOPED TO SYNTHESIZE INFRARED SCENE RADIANCES MEASURED BY IMAGING SENSORS. DETAILS OF THE PHYSICAL PROPERTIES OF THE CL ...

A KEY REQUIREMENT FOR THE SUCCESS OF THE NEW, TACTICAL RADIATION DOSIMETRY INSTRUMENTATION NOW BEING DEVELOPED BY THE ARMY IS TO HAVE AN ENERGY COMPENSATED, SOLID STATE GAMMA RAY SENSOR. ATTEMPS TO USE TRADITIONAL FILTERING TECHNIQUES TO ACHIEVE A FLAT ENERGY RESPONSE HAVE NOT BEEN SUCCESSFUL AND A NEW APPROACH IS REQUIRED. WE PROPOSE TO UTILIZE RECENTLY AVAILABLE, INEXPENSIVE DIGITAL MICROCHIPS T ...

A HIGH SPATIAL RESOLUTION AND HIGH SENSITIVITY X-RAY IMAGING SYSTEM HAS BEEN DEVELOPED THAT IS APPROPRIATE FOR THE IN-PROCESS INSPECTION OF SURFACE MOUNTED PRINTED CIRCUIT BOARD ASSEMBLIES. IT IS A NEAR REAL-TIME SYSTEM THAT PRODUCES HIGH-QUALITY DIGITAL IMAGES CAPABLE OF PROVIDING QUANTITATIVE DATA FOR FEEDBACK TO THE ASSEMBLY SOLDERING AND OTHER SURFACE MOUNTED TECHNOLOGY MANUFACTURING PROCESSES ...

THIS SOLICITATION RESPONSE DESCRIBES ACSI'S TEAM APPROACH IN DEFINING, ANALYZING AND EVALUATING THE FEASIBILITY OF THE NEW CONCEPTS PROPOSED FOR PERFORMING AIR TRAFFIC CONTROL (ATC) IN A TACTICAL WARTIME ENVIRONMENT. WE WILL SHOW HOW WE PROPOSE TO DEVELOP THE CONCEPTS SO THAT TERMINAL ATC SERVICES CAN BE MADE SAFE AND SURVIVABLE BY UPGRADING CURRENT EQUIPMENT TO INCORPORATE TECHNOLOGIES WHICH REDU ...

FOR PHASE I, AMSI PROPOSES TO IDENTIFY AND ESTABLISH THE TECHNICAL FEASIBILITY OF VARIOUS ADVANCED ACOUSTIC ARRAY CONCEPTS. THREE GENERIC APPROACHES ARE CURRENTLY IDENTIFIED: 1) OPTIMIZE THE SENSOR DESIGN (I.E., DIRECTIONAL SENSORS, ETC.), 2) OPTIMIZE HYDROPHONE/ GROUP/ARRAY GEOMETRY (I.E., MULTI-APERTURES, ETC.), AND 3) IMPLEMENT SIGNAL PROCESSING TECHNIQUES (I.E., VARIOUS ANALYTIC CONTINUATION T ...

THE SUCCESSFUL GROWTH OF GAAS ON SILICON SUBSTRATES USING DOUBLE SELECTIVE LIQUID EPITAXIAL (DSLE) PROCESS HAS RECENTLY BEEN ACCOMPLISHED. THESE RESULTS SET THE STAGE FOR THE DEVELOPMENT OF AN EXTREMELY USEFUL MATERIAL--LARGE PLANAR WAFERS OF SMOOTH GAAS ON SILICON. DOUBLE SELECTIVE LIQUID PHASE EPITAXY COULD SIGNIFICANTLY REDUCE THE PROBLEMS CAUSED BY LATTICE MISMATCH AND DIFFERENTIAL THERMAL EXP ...

THE ACTIVE SONARS TYPICALLY USED ON SUBMARINES OPERATE AT FREQUENCIES HIGH ENOUGH TO BE DIFFICULT IF NOT PRESENTLY IMPOSSIBLE TO MODEL ACCURATELY WITH FINITE ELEMENT ANALYSIS. LIKEWISE BEAM AND CYLINDER MODELS PROVIDE INADEQUATE REPRESENTATIONS OF THE HIGH FREQUENCY BEHAVIOR OF PLATE AND FRAME VIBRATIONS. THE APPLICATION OF THE AARC STATISTICAL ENERGY ANALYSIS PROGRAM WHICH INCLUDES BENDING, LONGI ...

THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO LIMIT VOLTAGE DELAY, ANODE CORROSION DURING INTERMITTENT USAGE AND TO INCREASE THE CURRENT CAPABILITY AND CAPACITY OF LI/SOCL(2) CELLS THROUGH THE USE OF NEW ELECTROLYTE SALTS. THE PRINCIPLES USED WILL BE THOSE WHICH HAVE SUCCEEDED IN THE PAST, NAMELY, BY LIMITING THE CONCENTRATION OF THE ELECTROLYTE SALT AND BY USING THE LITHIUM SALTS OF LARGE ANIONS W ...
