THE KEY PROBLEM TO BE ADDRESSED IN PHASE I OF THIS PROJECT WILL BE TO DETERMINE THE FEASIBILITY OF A NOVEL POSITION MEASURING SYSTEM FOR A FAMILY OF COMPUTER CONTROLLED MACHINE TOOLS. THE MULTIPLE LASER MEASUREMENT SYSTEM (MLMS), WHICH FORMS THE BASIS OF THIS PROPOSAL, WILL MEASURE THE (X, Y, Z) POSITION OF THE CUTTING HEAD DIRECTLY AT RATES AND ACCURACIES SUFFICIENT FOR CLOSED LOOP POSITION CONTR ...

FUTURE MILITARY AVIONICS SYSTEMS WILL REQUIRE AT LEAST AN ORDER OF MAGNITUDE IMPROVEMENT IN MEAN TIME BETWEEN CRITICAL FAILURES. TO ACHIEVE THIS GOAL INNOVATIVE FAIL-SAFE FAULT-TOLERANT ELECTRONIC SYSTEM DESIGN CONCEPTS WILL BE NEEDED. THE APPROACH PROPOSED BY DAINA WILL BE BASED ON THE USE OF EXTERNAL ENVIRONMENT DATA, BUILT-IN RELIABILITY MODEL, ADAPTIVE STATISTICAL SYSTEM STATE AND PARAMETER ES ...

A GENERAL USE CRYOREFRIGERATOR WILL BE DEVELOPED DURING PHASE I FOR LIQUEFYING NATURAL GAS TO FUEL PRIVATE AND COMMERCIAL VEHICLES. THE LIQUEFIER IS A NOVEL ARRANGEMENT OF AN AIR-CHARGED STIRLING SYSTEM THAT CAN BE CONFIGURED IN EITHER AN ELECTRICALLY POWERED OR A NATURAL-GAS-POWERED VERSION. THE LIQUEFIER SYSTEM INCORPORATES SEVERAL INNOVATIVE FEATURES TO ACHIEVE A RUGGED, COMPACT ARRANGEMENT WIT ...

BORON NEUTRON CAPTURE THERAPY (BNCT) USING THE (10)B(N, ALPHA)(7) LI REACTION OFFERS PROMISE AS A METHOD FOR SELECTIVE INTERNAL IRRADIATION OF TUMORS. (10)B-SUBSTITUTED AMINO ACIDS, NUCLEOSIDES, AND ANTIBODIES HAVE BEEN DEVELOPED TO TARGET TUMORS. RECENTLY, EXCITING DATA HAS BEEN GENERATED WITH BORONATED PORPHYRINS AND CAGED DODECABORANE SULFHYDRYL COMPOUNDS AS BNCT AGENTS. SINCE EFFECTIVE BNCT MA ...

THE MATERIALS REQUIREMENTS FOR THE PYROMETALLURGICAL REPROCESSING OF SPENT NUCLEAR FUEL ARE QUITE DEMANDING. IN FACT, CURRENTLY AVAILABLE MATERIALS LIMIT PYROMETALLURGICAL REPROCESSING. INNOVATIVE CERAMIC COMPOSITES OFFER THE OPPORTUNITY TO OVERCOME CURRENT MATERIALS LIMITATIONS AND PROVIDE NONREACTIVE AND NONWETTABLE CONTAINERS TO MOLTEN AND/OR VAPORIZED METALS AND SALTS FOR PYROMETALLURGICAL REP ...

THE COMPLETE DESIGN IS PRESENTED WITHIN THIS PROPOSAL FOR A SYSTEM WHICH WILL PROVIDE A PRECISE, ONE-STEP CONVERSION DIRECTLY FROM A PULSE TRAIN INPUT TO A DIGITIZED PULSE RATE OUTPUT. IT IS A DISTRIBUTED PROCESSOR SYSTEM EMPLOYING A MASTER CONTROL PROCESSOR AND FROM 2 TO 30 IDENTICAL PULSE MODULES. THE PULSE MODULE IS A STANDALONE UNIT WHICH PERFORMS THE PULSE PERIOD MEASUREMENT. THE MICROPROCESS ...

THE PREDICTION OF MESOSCALE DISPERSION, FOR EMERGENCY RESPONSE PURPOSES, IS CRITICALLY DEPENDENT UPON ACCURATELY FORECASTING THE 3-D WIND FIELD WITHIN THE DOMAIN OF INTEREST SEVERAL HOURS IN ADVANCE. CURRENTLY AVAILABLE EMERGENCY RESPONSE SYSTEMS, WHICH TYPICALLY USE SOME FORM OF GAUSSIAN DIFFUSION MODEL COMBINED WITH WIND FIELDS INTERPOLATED FROM SCATTERED SURFACE LAYER WIND MEASUREMENTS, ARE, UN ...

MANIKINS ARE CURRENTLY FABRICATED WITH A SKELETON OF METAL "BONES" WHICH PROVIDE THE STRUCTURAL STRENGTH REQUIRED TO WITHSTAND THE REPEATEDLY HIGH ACCELERATIONS AND LOADS OF DYNAMIC TESTING. SUCH METAL STRUCTURES, HOWEVER, DO NOT EXHIBIT PROPER SEGMENT INERTIAL DISTRIBUTION OR LOAD-DEFORMATION PROPERTIES, WHICH MAKES IT DIFFICULT TO DESIGN MANIKINS FOR BIOFIDELIC RESPONSE. FOR THIS REASON, IT IS P ...
