THE ADVANTAGES OF THERMOPLASTIC MATRIX COMPOSITES FOR MANUFACTURING LOW-COST CMPONENTS HAVE YET TO BE REALIZED. AN IMPORTANT FACTOR LIMITING THERMOPLASTIC COMPOSITES IS THE LACK OF LOW-COST METHOD FOR PRODUCING HIGH-QUALITY PREPREGS AND PREFORMS. A METHOD OF PRODUCING THESE MATERIALS THAT IS COMPATIBLE WITH COMMONLY USED COMPOSITE FABRICATION TECHNIQUES SUCH AS FILAMENT WINDING, PULTRUSION, AND PR ...

THIS PROPOSAL IS FOR DEVELOPMENT OF A NEW GENERATION OF AGC-TYPE POWER SYSTEM MODELS/SIMULATORS. THE DEVELOPMENT WILL REQUIRE RECONSIDERATION OF MODEL COMPONENTS IN THE LIGHT OF TIME-SCALE SEPARATION METHODOLOGY, DEVELOPMENT OF APPROPRIATE TRANSMISSION PLANT THERMAL MODELS AND OF BUS VOLTAGE CONTROL DEVICE MODELS, AND DEVELOPMENTS IN NETWORK PROCESSING TECHNIQUES. THE RESULT WILL BE A PC-BASED AGC ...

VOLATILE HALOGENATED ALIPHATIC COMPOUNDS (VHALS) ARE PREDOMINANT CONTAMINANTS AT HAZARDOUS WASTE SITES. TRICHLOREOTHYLENE (TCE) IS THE MOST COMMONLY OCCURING COMPOUND IN THIS CLASS. THESE COMPOUNDS ARE PERSISTENT AND THEREFORE REQUIRE SOME FORM OF REMEDIATION OF REMOVAL. PRESENT TECHNOLOGY UTILIZES CARBON ADSORPTION, WHICH MEANS TRANSFERRING THE HAZARDOUS COMPOUNDS TO ANOTHER MEDIUM WHICHMUST BE D ...

A NEW CONCEPT OF A SLURRY ELECTROLYTE CELL FOR PRIMARY ALUMINUM EMPLOYING A NON-CONSUMABLE ANODE IS PRESENTED. THE FINE-PARTICLE ALUMINA SLURRY CONCEPT ALLOWS CELL OPERATION AT A TEMPERATURE OF 700 DEGREES CENTIGRADE AS COMPARED TO 950 DEGREES-980 DEGREES CENTIGRADE IN CONVENTIONAL HALL-HERAULT CELLS. THE LOWER OPERATING TEMPERATURE IS EXPECTED TO MAKE PRACTICAL THE STATE-OF-THE-ART CERMET ANODES ...

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 ...

RESEARCH IS PROPOSED ON ROBUST METHODS FOR ANALYSIS OF VARIANCE (ANOVA) AND ON STATISTICALLY DESIGNED EXPERIMENTS (SDE), WITH A VIEW TOWARD IMPLEMENTATION IN MODERN INTERACTIVE GRAPHICS WORKSTATION ENVIRONMENTS. THE FOLLOWING ROBUSTNESS CONCEPTS AND TOOLS WILL BE USED: INFLUENCE FUNCTIONS, HIGH BREAKDOWN POINT ESTIMATION, MIN-MAX BIAS ROBUST ESTIMATION, AND MEAN-SQUARED ERROR EFFICIENCY ROBUSTNESS ...

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 ...
