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 ...

THE ARCHITECTURAL FEASIBILITY OF A GENERIC COMPUTER VISION SYSTEM COMPOSED OF HETEROGENEOUS PROCESSORS IS EXAMINED. THE STUDY FOCUSSES ON ISSUES SUCH AS THE NATURE OF THE HETEROGENEOUS PROCESSORS FUNCTIONAL CAPABILITIES, NETWORK REALIZATION TRADEOFFS, AND COMMON MODULE INTERFACES. THE GENERIC COMPUTER VISION SYSTEM IS DESIGNED TO MEET THE DEMANDS IMPOSED BY FUTURE INDUSTRIAL VISION APPLICATIONS, I ...

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 ...

THE PROPOSED RESEARCH IS DIRECTED TOWARD ACCESSING THE FEASIBILITY OF USING THE GREEN ALGAE CHLORELLA AND ITS INFECTION BY A NATURALLY OCCURRING VIRUS AS AN EXPERIMENTAL PLANT SYSTEM. THE VIRUS, PARAMECIUM BURSARIA CHLORELLA VIRUS-1, PBCV-1, WILL BE INVESTIGATED TO DETERMINE ITS POTENTIAL AS A MOLECULAR VEHICLE TO INTRODUCE FOREIGN DNA INTO PLANT CELLS. SPECIFICALLY, ANALYSIS OF VIRAL MUTANTS AND ...

Oscilla Power, Inc. (OPI) is developing a utility-scale wave energy harvester that is enabled by low cost and readily-available magnetostrictive alloys. T his device, which utilizes no moving parts, has the potential to deliver predictable quantities of electric power to coastal utilities, industrial users, and remote facilities at costs competitive with coal or gas. The Phase I project demonstra ...

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 ...

TWO MAJOR OBSTACLES CONFRONTED PREVIOUS ATTEMPTS TO ANALYZE FIELD ICE BEHAVIOR; NAMELY: THE LACK OF PROPER CONSTITUTIVE LAWS TO MODEL REALISTIC ICE BEHAVIOR, PARTICULARLY AT HIGH STRAIN-RATES, AND THE DIFFICULTY IN INCORPORATING LARGE ICE DEFORMATIONS IN THE ANALYSIS. THIS PROPOSAL PRESENTS A STUDY WHICH WILL IMPLEMENT AN ICE CONSTITUTIVE MODEL SUBROUTINE TO WORK IN CONJUNCTION WITH A LAGRANGE EXP ...

TRA PROPOSES THE DEVELOPMENT OF A NOVEL, NON-CAKING ULTRASONIC FILTER. THE DEVICE USES STANDARD FILTER MEMBRANES PLACED IN AN ACOUSTIC FIELD THAT TRAPS AND TRANSPORTS PARTICLES AWAY FROM THE FILTER SURFACE. BOTH SOLID AND FLUID PARTICLES SUSPENDED IN A FLUID MEDIUM MAY BE ACTED UPON BY THE MOVING PRESSURE SURFACES. PARTICLES SIZED BETWEEN 0.5 AND 0.1 MICROMETRES HAVE BEEN TRANSPORTED BY THIS TECHN ...
