MATERIAL COMPATABILITY BETWEEN LIQUID METAL CURRENT COLLECTOR ALLOYS AND SOLID METALS ON MATERIAL COLLECTOR SURFACES WILL BE INVESTIGATED. LOW MELTING FUSIBLE TYPE ALLOYS WITH CAPABILITY OF OPERATING AT 200 DEG F OR BELOW WILL BE FEATURED WITH SOME CONSIDERATION OF SUITABLE MATERIALS IN THE 0-500 DEG F RANGE. A THOROUGH LITERATURE SEARCH FOR PERTINENT PHYSICAL, MECHANICAL, AND SURFACE INTERACTIVE ...

RIGID, LOW DENSITY POLYURETHANE FOAM IS WIDELY USED IN CUSHIONING AND FLOTATION APPLICATIONS. IT DOES POSSESS CERTAIN DISADVANTAGES, INCLUDING COMBUSTABILITY, TOXIC GAS EVOLUTION IN A FIRE AND POOR DIMENSIONAL STABILITY. PHENOLIC FOAMS ARE MORE STABLE, DO NOT SUPPORT COMBUSTION AND LACK THE FUNCTIONAL GROUPS RESPONSIBLE FOR THE GASES, BUT THEY LACK STRENGTH AND RESISTANCE TO ABRASION. WE PROPOSE T ...

THE PROPOSED RESEARCH PROBLEM IS TO DEVELOP A SENSOR, TOGETHER WITH A MATHEMATICAL ALGORITH, THAT WILL ALLOW THE THREE- DIMENSIONAL QUANTITATIVE EDDY-CURRENT NONDESTRUCTIVE EVALUTION OF MATERIALS AND STRUCTURES. THE APPROACH THAT WE PROPOSE IS BASED ON, AND EXTENDS WORK ON TWO-DIMENSIONAL EDDY-CURRENT NDE THAT THAT HAS ALREADY BEEN PERFORMED BY ANALYTIC, INC. THAT WORK IS BRIEFLY REVIEWED. THE TEC ...

THE PROPOSED RESEARCH PROBLEM IS TO DEVELOP A MODEL AND AN INVERSION ALGORITHM THAT IS SUITABLE FOR THE THREE-DIMENSIONAL QUANTITATIVE NON-DESTRUCTIVE EVALUATION (NDE) OF ADVANCED COMPOSITE MATERIALS BY USING EDDY-CURRENTS. THE APPROACH THAT WE PROPOSE IS BASED ON, AND EXTENDS, WORK THAT HAS ALREADY BEEN PERFORMED BY ANALYTICS, INC. FOR EDDYCURRENT NDE OF CONVENTIAL METALS. THE TECHNICAL OBJECTIVE ...

THIS PROPOSAL DESCRIBES A RESEARCH PROGRAM TO DEVELOP FAST ALGORITHMS FOR REAL-TIME ESTIMATION, PREDICTION AND CONTROL. SUCH ALGORITHMS WOULD PROVIDE A SOLUTION TO A CRITICAL PROBLEM FACED IN BOTH INDUSTRIAL AND MILITARY APPLICATIONS - - THE FACT THAT THE ALGORITHMS USED TO IMPLEMENT STATE-OF-THE-ART STATISTICAL ESTIMATION, PREDICTION AND CONTROL TECHNIQUES ARE FAR TOO SLOW FOR MANY REAL-TIME OR N ...

IN THE PROPOSED RESEARCH WE WILL BE DETERMINING THE BIT ERROR RATE FOR 64K AND 256K DRAM AS A FUNCTION OF ALPHA PARTICLE RADIATION DOSE. THREE PARAMETERS WILL BE VARIED: THE DEVICE (CHIPS FROM DIFFERENT MANUFACTURERS WILL BE CHOSEN), THE BOMBARDING PARTICLE ENERGY, AND THE BEAM CURRENT. THIS INFORMATION SHOULD ALLOW AN ACCURATE EVALUATION OF THE NUMBER OF SOFT FAILS DUE TO ALPHA PARTICLES FROM TER ...

FABRICATION OF PROPELLANT TANKS INVOLVES COSTLY EXTENSIVE MACHINING OF THICK TI-6AL-4V FORGINGS. TWO PROMISING APPROACHES FOR TI-15V3CR-3SN AND HOT SUPERPLASTIC FORMING (SPF) OF TI-6AL-4V. SPF REQUIRES LOW FORMING PRESSURE, HAS EXCELLENT SHAPE CAPABILITY AND IS APPLICABLE TO WELL ESTABLISHED TI-6AL-4V. BUT, IT REQUIRES COSTLY TOOLING AND HEATING SYSTEMS. THE PROPOSED PROGRAM WILL INVESTIGATE A NOV ...
