RESEARCH AND DEVELOPMENT WILL BE CARRIED OUT TO PROVIDE PROTOTYPE, ACTIVELY CONTROLLED GAS BEARINGS FOR PRECISION MOVEMENT IN INSTRUMENTS AND MACHINE TOOLS. THIS WILL DRAW UPON PRELIMINARY WORK ON (1) FABRICATION, (2) DYNAMIC ANALYSIS OF THE BEARING AND SUPPORTED MASS, (3) PIEZOELECTRIC VALVING AND PIEZOELECTRIC DISPLACEMENT OF THE BEARING SURFACE, AND (4) THE ADAPTATION OF A MICROPROCESSOR TO SER ...

THE CONTRACTOR SHALL DEVELOP A FUZZY SET METHODOLOGY FOR UNCERTAINTY ANALYSIS IN PROBABILISTIC SEISMIC SAFETY ASSESSMENT OF NUCLEAR POWER PLANTS. FUZZY SET LOGIC WILL BEUSED FOR COLLECTING, QUANTIFYING AND PROPAGATING SUBJECTIVE,ENGINEERING JUDGEMENT USED IN THE UNCERTAINTY ANALYSIS. IN PHASE I, FEASIBILITY OF THE PROPOSED APPROACH WILL BE DEMONSTRATED BY APPLYING IT TO SELECTED PARTS OF A PROBABI ...

RESEARCH ON AN ALTERNATE MATERIAL, ANHYDRITE CALCIUM SULFATE, FOR USE AS CULTCH IN CONSTRUCTING SEED BEDS AND ARTIFICIAL OYSTER REEFS IS HEREIN PROPOSED. GIVEN THE FACTS THAT OYSTER PRODUCTION IN THE UNITED STATES HAS DECLINED GREATLY SINCE 1908 AND THAT NATURAL OYSTERSHELL IS SCARCE AND EXPENSIVE, MOTIVATION FOR USE OF THIS ALTERNATE MATERIAL AS CULTCH INCLUDES ITS CONTINUOUS PRODUCTION, LOW COST ...

THE FEASIBILITY OF USING A CONVENTIONAL 3-CUP ANEMOMETER AND A HEATED THERMISTOR TO OBTAIN WIND SPEED AND WIND DIRECTION IS PROPOSED. THE TECHNIQUE ONLY REQUIRESKNOWLEDGE OF MONITORING THE ROTATION RATE OF THE ANEMOMETER AND DETERMINING THE PEAK RESPONSE OF A HEATED THERMISTOR WHICH IS EXPOSED TO THE FLOW ONCE WITH EACH REVOLUTION OF THE CUP ANEMOMETER VIA A SENSING PORT. THE TECHNIQUE DOES NOT RE ...

RESEARCHERS ARE INVESTIGATING THE FEASIBILITY OF MEASURING TO VERY HIGH RESOLUTION THE LOCATIONS OF MULTIPLE COMPONENTS OF KNOWN COMPOSITION WHOSE POSTITIONS ARE INTENDED TO CONFORM TO A WELL-DEFINED PATTERN INSIDE A STRUCTURE. THE TECHNIQUE DEPENDS ON SCANNING PHOTON BEAMS ACROSS THE STRUCTURE SURFACE, DETECTING TRANSMITTED AND SCATTERED RADIATION IN COLLIMATED DETECTORS, AND EMPLOYING TECHNIQUES ...

THIS PROJECT INVOLVES THE DEVELOPMENT OF A NEW TECHNIQUE FOR THE GENERATION OF COMPLEX THREE-DIMENSIONAL STRUCTURES DIRECTLY FROM A CAD/CAM DATABASE WITHOUT THE NEED FOR PRELIMINARY PROCESSES (MOLDS) OR SUBSEQUENT MACHINING (THE PARTS ARE FABRICATED TO NET SHAPE). THE INNOVATION IS TO USE INDEPENDENTLY TARGETED PARTICLES OF METAL OR COMPOSITE METAL TO BUILD STRUCTURES UNDER COMPUTER CONTROL IN MUC ...

A NEURAL NETWORK ARCHITECTURE CALLED THE PARAMETRIC AVALANCHE SCHOLASTIC FILTER, WAS DEVELOPED TO SOLVE DIFFICULT PROBLEMS DEALING WITH NONLINEAR DYNAMICAL SYSTEMS. RESEARCHERS ARE APPLYING THIS NETWORK ARCHITECTURE TO AUTOMATIC RECOGNITION OF SPEECH. ADDITIONALLY, RESEARCH IN THE FIELD OF ACOUSTIC EMISSION IN VARIOUS STRUCTURES, PARTICULARLY AS APPLIED TO FATIGUE MONITORING IS BEING CONDUCTED. ...

RESEARCHERS ARE DEVELOPING MM WAVE SIS HETERODYNE RECEIVERS INTEGRATED WITH ON CHIP LOCAL OSCILLATORS FOR USE IN RADIO ASTRONOMY. THE RECEIVERS INCORPORATE SUPERCONDUCTING TUNNEL JUNCTIONS (SIS JUNCTIONS) AS THE MIXING ELEMENTS, TOGETHER WITH JOSEPHSON JUNCTION LOCAL OSCILLATORS, TO PROVIDE MIXING IN THE 50-700 GHZ FREQUENCY BAND. LOCAL OSCILLATORS BASED ON THE AC JOSEPHSON EFFECT HAVE DEMONSTRA ...

IMMOBILIZED FORMS OF ENZYMES HAVE OUTSTANDING PROMISE AS INDUSTRIAL CATALYSTS TO MAKE OR MODIFY PRODUCTS; AND ADVANCES IN IMMOBILIZED ENZYME TECHNOLOGY CAN HAVE A MAJOR ECONOMIC IMPACT ON THE PRODUCTION OF FOODS AND OTHER MATERIALS. ENZYME TECHNOLOGY RESEARCH GROUP, INC. IS DESIGNING THE DEVELOPING UNIQUE CARRAGEENAN-BASED SUPPORTS FOR IMMOBILIZED ENZYMES. THE OBJECTIVE OF THIS PROJECT IS TO DESIG ...

AN "INHALATION SCREENING DOSE COLLAR-STANCHION MONITOR" WITHEMBEDDED MINIATURE THIN-WALL GEIGER-MUELLER RADIATION DETECTORS EVALUATES THE THYROID GLAND FOR NANOCURIE ACTIVITYINVENTORY. THE PRIMARY TECHNICAL OBJECTIVE IS TO ESTABLISH THAT THE "COLLAR-STANCHION MONITOR" WILL BE CAPABLE OF DETECTING WITHIN 15 SECONDS AND WITH 2 SIGMA CONFIDENCE AN ACTIVITY INVENTORY OF 0.7 NANOCURIES OF I-131 DOSE EQ ...
