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 ...

A NOVEL SPEECH CODING TECHNIQUE FOR MOBILE VOICE COMMUNICATIONS APPLICATIONS IS PROPOSED. THE TECHNIQUE UTILIZES THE FREQUENCY AND TIME-VARYING PROPERTIES OF SPEECHIN CONJUNCTION WITH A SPEECH QUALITY PERCEPTION CRITERION TOPROVIDE HIGH QUALITY AND NATURAL-SOUNDING SPEECH OVER A WIDERANGE OF BIT RATES (2.4 - 16.0 KBIT/S). THE TECHNIQUE IS ROBUST TO TRANSMISSION ERRORS, PROVIDES A FRAME-WORK FOR VA ...

WITH THE INCREASE IN OUR DEPENDENCE ON COMPUTERS IN ALL PHASES OF OUR LIVES, IT IS BECOMING IMPERATIVE THAT, AS FAR AS POSSIBLE, THE COMPUTERS BE FAULT-TOLERANT, I.E. BE CAPABLE OF PERFORMING IN THE PRESENCE OF FAILURES. ONE CRITICAL ASPECT OF FAULT-TOLERANT COMPUTING IS THE NECESSITYTO DESIGN TESTABLE VLSI CIRCUITS. IN THIS RESEARCH PROPOSAL, A NEW TECHNIQUE FOR BUILT-IN-TEST (BIT) OF VLSI CIRCUI ...

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 ...

N/A

THE FEASIBILITY OF MODIFYING AN AQUEOUS NAOH SOLUTION TO PROVIDE A HIGHER LIFT AND LESS CORROSIVE ABSORBENT FOR USE IN ABSORPTION CYCLES IS EXAMINED. THE PROPERTIES THAT ARE PROJECTED (AND IN SOME CASES ALREADY CONFIRMED) FOR THE MODIFIED ABSORBENT HAVE LONG BEEN SOUGHT BY RESEARCHERS IN THE ABSORPTION FIELD. THE IMPROVEMENTS WILL LOWER COSTS IN TRADITIONAL ABSORPTION CYCLE MARKETS, EG. AIR COOLED ...
