WE PROPOSE A PROGRAM TO FABRICATE SINGLE MODE SYMMETRIC WAVEGUIDES IN ALXGA1-XN, AND TO MEASURE THE ELECTRO-OPTICAL PROPOERTIES OF THE MATERIAL SYSTEM. OUR PROGRAM IS SIGNIFICANT DUE TO THE POTENTIAL OF USING ALXGA1-XN WAVEGUIDES FOR UNIQUE ELECTRO-OPTIC DEVICES OPERATING IN THEULTRAVIOLET AND VISIBLE PARTS OF THE SPECTRUM. WE SPECIFICALLY DESIRE TO FABRICATE SUCH A SOLID STATE LASER SCANNER UNDER ...

A LARGE NUMBER OF TOXINS (SUCH AS PARALYTIC SHELLFISH TOXINS, TETRODOTOXIN, AND BACTRACHOTOXIN) ARE POTENTIALLY LETHAL CONTAMINANTS IN SEAFOOD SAMPLES. THESE TOXINS ARE KNOWN TO ACT BY ALTERING THE CONDUCTANCE PROPERTIES OF A WELL-CHARACTERIZED SODIUM CHANNEL FOUND IN MUSCLES AND NERVES. IN THIS STUDY, WE WILL PREPARE AN ENZYME-LINKED ASSAY TO DETECT THESE TOXINS: ENZYME- OR COENZYME-TOXIN CONJUGA ...

SCIENTIFIC AND REGULATORY CONSIDERATIONS DICTATE THAT MANY VACCINES AND GENETICALLY ENGINEERED PROTEINS FOR USE IN IN HUMANS ARE BEST PRODUCED IN MAMMALIAN CELL LINES DERIVED FROM NON-MALIGNANT SOURCES. THESE CELLS USUALLY REQUIRE A SURFACE UPON WHICH TO GROW, AND SEVERAL BIOREACTOR CONFIGURATIONS HAVE BEEN DEVELOPED WHICH HAVE LARGE SURFACE AREAS COMPRESSED INTO SMALL VOLUMES, THEREBY IMPROVING T ...

AS THE UNITED STATES MOVES TO JUST-IN-TIME MANUFACTURING, THERE WILL BE INCREASED EMPHASIS ON RAPID AND ACCURATE INSPECTION TECHNIQUES. FOR THESE REASONS, RESEARCH AIMED AT THE ULTIMATE DEVELOPMENT OF A HIGH ACCURACY, MINIATURE PROBE CAPABLE OF INSPECTING MANUFACTURED PARTS WITH COMPLEX GEOMETRIES IS PROPOSED. A NOVEL LASER BASED, NON-CONTACT INSPECTION TECHNIQUE FOR PRECISION MEASUREMENTS OF INTE ...

THE COMPLEXITY OF THE NEXT-GENERATION FAULT-TOLERANT ELECTRONIC SYSTEM DESIGN TASKS WILL REQUIRE INTERACTIVE ACCESS TO THE RELIABILITYPREDICTION TOOLS IN ORDER TO ACHIEVE THE DESIRED RELIABILITY GOALS. THIS PROPOSAL ADDRESSES THE INTEGRATION OF THE AFHRL DEVELOPED MISSION RELIABILITY MODEL (MIREM) AND THE AVAILABLE CIRCUIT DESIGN PROGRAMS IN AN ENGINEERING WORKSTATION ENVIRONMENT. THE PROPOSED EFF ...

CURRENTLY AVAILABLE AUTHORING SYSTEMS HAVE BEEN PROVEN EFFECTIVE IN PRODUCING COMPUTER-BASED TRAINING LESSONS CONTAINING SEQUENCES OF TEXT AND GRAPHICS SCREENS THROUGH WHICH THE STUDENT IS GUIDED UNTIL MASTERY IS ACHIEVED. IN A PERSONNEL TRAINING SIMULATION, FAR MORE ADVANCED CAPABILITIES ARE REQUIRED, INCLUDING MULTITASKING, COMMUNICATION WITH EXTERNAL DEVICES, HIGH SPEED DATA ANALYSIS AND GRAPHI ...

IT IS PLANNED TO DEVELOP A WORKSTATION ENVIRONMENT FOR THE ADVANCED THERMAL HYDRAULIC ENERGY NETWORK ANALYZER (ATHENA) CODE TO FACILITATE FUSION REACTOR DESIGN STUDIES. ATHENA HAS A WIDE RANGE OF CAPABILITIES AND IS AN ESSENTIAL TOOL FOR THE STUDY OF FUSION REACTOR DESIGN. THE PERSONAL-COMPUTER (PC)-BASED WORKSTATION ENVIRONMENT FOR ATHENA WILL STREAMLINE AND AUTOMATE THE DEVELOPMENT OF INPUTDECKS ...

ROCK MASSES ARE THE HOST MEDIA FOR ENGINEERING VENTURES OF MAJOR ECONOMIC AND DEFENSE SIGNIFICANCE. THE PERFORMANCE OFA ROCK MASS UNDER ENGINEERING CONDITIONS IS USUALLY DOMINATED BY THE DISCONTINUOUS NATURE OF THE MEDIUM. HOWEVER, THE TECHNIQUES OF DESCRIBING THE TOPOGRAPHY OF DISCONTINUITIES OR JOINTS, WHICH STRONGLY INFLUENCE THEIR PROPERTIES, AND OF EXPERIMENTALLY MEASURING THEIR MECHANICALPRO ...
