NANOCRYSTALLINE MATERIALS PROVIDE SUPERIOR MECHANICAL PROPERTIES COUPLED WITH IMPROVED WEAR AND CORROSION RESISTANCE. RESEARCHERS ARE DEMONSTRATING THE ABILITY TO DEVELOP A NUMBER OF NANOCRYSTALLINE MATERIALS USING PULSED REACTIVE ELECTRODES (PRE-EITHERIN THE FORM OF A ROD OR WIRE OR, IN SOME CASES, BRAIDED WIRES) SUBMERGED IN A REACTIVE OR NONREACTIVE DIELECTRIC FLUID. CONTROL OVER THE PROCESSING ...

AN INTEGRATED SENSOR SYSTEM EMPLOYING HIGH-PRECISION ULTRASOUND RANGEFINDING INSTRUMENTS COMBINED WITH A CHARGED-COUPLE DEVICE (CCD) VIDEO PROCESSOR CAN BE USED TO DETERMINE THE PRECISE POSITION AND MOTION OF CONTAINER SHIPSBEING LOADED AT A PIER. PROCESSING WILL BE CARRIED OUT BY ATWELVE STATE KALMAN FILTER WHICH RELIES ON FEEDBACK FROM THELOADING CRANE'S AUTOMATIC CONTROL PROCESSOR FOR GOOD A PR ...

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 ...

THE DISCOVERY OF HIGH-TEMPERATURE SUPERCONDUCTIVITY IN RARE-EARTH COPPER OXIDE CERAMIC SYSTEM HAS LED TO CONSIDERABLE RESEARCH DIRECTED TOWARD THE DEVELOPMENT OF ELECTROMAGNETIC COMPONENTS AND DEVICES. HOWEVER, THE APPLICATION OF HIGH CRITICAL TEMPERATURE (TC) SUPERCONDUCTORS HAS BEEN LIMITED BECAUSE OF CRYSTAL ANISOTROPY OF THE RANDOMLY ORIENTED GRAINS IN POLYCRYSTALLINE MATERIALS, GRAIN BOUNDARY ...
