RESEARCHERS ARE DEVELOPING AN INNOVATIVE NEW APPROACH TO LABORATORY TRAINING IN HEALTH PHYSICS, I.E., THE DEVELOPMENT OF A COMPUTER SIMULATOR THAT CAN BE USED IN PLACE OF ACTUAL RADIATION SOURCES IN LABORATORY TRAINING. SUCH A SIMULATOR RESULTS IN MUCH LOWER COST OF TRAINING, PROVIDES FOR A WIDER VARIETY OF TRAINING SITUATIONS, AND ELIMINATES THE SAFETY HAZARDS ASSOCIATED WITH ACTUAL RADIATION SOU ...

PREDICTION OF CATASTROPHIC AND COSTLY FAILURES IN STRUCTURALCOMPONENTS HAS BEEN HAMPERED BY THE INABILITY TO MEASURE STRESS LEVELS IN CRITICAL COMPONENTS WITH ACCURACY. THIS PROPOSAL DESCRIBES THE STEPS NEEDED TO DEVELOP A STRESS MEASUREMENT SYSTEM THAT RELIES ON ULTRASONIC (ACOUSTOELASTIC) WAVE MEASUREMENTS. THE RECENT ADVANCEMENTSMADE IN THE USE OF CRITICALLY REFRACTED LONGITUDINAL WAVES (CRLW), ...

RESEARCHERS ARE DEVELOPING AND DEMONSTRATING ADAPTABLE VIBRATION ANALYSIS SENSORS WHICH USE SPECIALIZED WEIGHTED-SENSITIVITY OPTICAL FIBER WAVEGUIDE STRUCTURES. SEVERAL METHODS TO CREATE THE NECESSARY SENSITIVITY VARIATIONS ALONG THE LENGTH OF THE WAVEGUIDE ARE SUGGESTED. EXTENSIONS OF THIS WORK TO FURTHER PERMIT THE REAL-TIME MODIFICATION OF SUCH SPATIAL FIBER SENSITIVITY PROFILES, AND HENCE THE ...

THIS RESEARCH WILL ADDRESS SOME KEY TECHNICAL PROBLEMS THAT WILL NEED TO BE RESOLVED BEFORE PROCEEDING WITH THE DEVELOPMENT OF A COMPREHENSIVE AND FLEXIBLE SET OF ADA PROGRAM QUALITY ENHANCING TOOLS, THE ADA QUALITY TOOLSET (AQT). THESE TOOLS WILL SUPPORT ADA SYSTEM DEVELOPERS BY CHECKING, AND WHERE APPROPRIATE ENFORCING, A SET OF ADA PROGRAMMING STYLE GUIDELINES. SPECIFIC TOOLSETS WILL BE CONFIGU ...

A DIFFUSING-VORTEX METHOD, FOR SOLVING THE TWO-DIMENSIONAL INCOMPRESS NAVIER-STOKES EQUATION, WILL BE EXTENDED AND APPLIED TO THE EXTERNAL INCOMPRESSIBLE VISCOUS FLOW OVER A GENERALLY SMOOTH BLUNT BODY. THE NUMERICAL ADVANTAGES OVER OTHER LAGRANGIAN VORTEX METHODS WILL BE FURTHER DEMONSTRATEDBY REDUCING TOTAL CPU TIME AND BY AVOIDING CUT-OFF PROCEDURES. THE NEW APPROACH WHICH IS AN APPROXIMATE EXP ...

TODAY'S COMPLEX SYSTEM ENVIRONMENT AND COMPETITIVE ECONOMIC ENVIRONMENT DEMAND PRECISE ANSWERS TO QUESTIONS CONCERNING DEPENDABILITY AND QUALITY. CURRENT TOOLS ARE NOT PROVIDING THE ABILITY TO MODEL COMPLEX FAULT HANDLING SCENARIOS AND OFTEN REQUIRE SIMPLIFYING ASSUMPTIONS ABOUT FAILURE RATES, REPAIR RATES, AND INITIAL STATES WHICH LEAD TO INCORRECT SOLUTIONS. ACCURATE DEPENDABILITY EVALUATIONS AR ...
