THIS RESEARCH PROJECT WILL STUDY THE FEASIBILITY OF DEVELOPING A 3-AXES ACOUSTIC DOPPLER VELOCIMETER SUITABLE FOR HIGH RESOLUTION TURBULENCE MEASUREMENTS AT A SINGLE POINT. THE PROPOSED APPROACH UTILIZES INTERRUPTED CONTINUOUS WAVE ACOUSTIC TRANSMISSION WITH THE WATERMASS SAMPLING VOLUME DEFINED BY THIS INTERSECTION OF MULTIPLE CROSSBEAMS. THE PRIMARY PHASE I OBJECTIVES ARE TO ANALYTICALLY DEFINE ...

THE PROBLEM OF INCREMENTAL OVERLOAD RESOLUTION IS NOW THE KEY IMPEDIMENT TO THE DEVELOPMENT OF INCREMENTAL COMPILERS FOR ADA AND OTHER MODERN PROGRAMMING LANGUAGES APPROPRIATE FOR LARGE-SCALE SOFTWARE DEVELOPMENT. THE OBJECTIVE OF THISPROPOSAL IS TO DEVELOP, ANALYZE, AND MEASURE A HIGH-PERFORMANCE ALGORITHM FOR INCREMENTAL OVERLOAD RESOLUTION AND TO EXAMINE THE FEASIBILITY OF COMBINING THAT ALGORI ...

ION IMPLANTATION HAS BEEN DEMONSTRATED TO BE THE LEADING FABRICATION TECHNOLOGY FOR HIGHLY UNIFORM DOPING OF SEMICONDUCTORS. HOWEVER, SEVERAL PROBLEMS ASSOCIATED WITH ION IMPLANTATION NOW HINDERS THE PROGRESS OF GAAS ICS, AFFECTING KEY AREAS OF PERFORMANCE, RELIABILITY AND YIELD. THESE DIFFICULTIES ARE LARGELY DUE TO LACK OF A RELIABLE, REPRODUCIBLE SURFACE ENCAPSULATION TECHNIQUE AND A MORE FUNDA ...

THE GROUP VIB DIATOMIC MOLECULES HAVE BEEN STUDIED EXTENSIVELY IN SPECTROSCOPY FOR MANY YEARS. THUS FAR, ONLY TWO HOMONUCLEAR DIATOMIC SPECIES HAVE HASED, S2 AND TE2. IT APPEARS THAT DISCHARGE DISSOCIATION OF SELENIUM VAPOR MAY LEAD TO A SUFFICIENT DIATOMIC POPULATION TO ALLOW LASER ACTION WITHOUT THE NEED FOR HIGH TEMPERATURE APPARATUS. THEGOAL OF THE PROPOSED RESEARCH IS TO ACHIEVE LASER ACTION ...

AS NUCLEAR PLANTS GROW OLDER, ENVIRONMENTAL CONDITIONS MAY AFFECT THE PERFORMANCE OF PLANT CONCRETE AND STEEL STRUCTURES. WE PROPOSE TO DEVELOP A STRATEGY WHICH CAN BE APPLIED TO CONCRETE STRUCTURES. IT WILL BE DIRECTED TOWARDSTHE DEVELOPMENT OF METHODS TO ANALYZE AND UNDERSTAND AGING EFFECTS, INCLUDING THE COMBINED EFFECTS OF TIME, TEMPERATURE, RADIATION, HUMIDITY, STRESS, CHEMICAL ENVIRONMENT AN ...

ALTHOUGH LARGE SUMS OF MONEY ARE BEING INVESTED IN THE DEVELOPMENT OF LAND-BASED TANK CULTIVATION OF ABALONE, NO ONE HAS DEVELOPED A POLYCULTURE TECHNOLOGY FOR LARGE-SCALE IN-THE-SEA CULTIVATION OF BOTH ABALONE AND ITS MACROALGAL FOODS. WE PROPOSE TO TEST THE FEASIBILITY OF ABALONE-ALGAE POLYCULTURE INTHE SEA USING INNOVATIVE MARINE FARMS THAT SUPPORT SPECIAL PLASTIC AND FIBERGLASS-MESH CONTAINERS ...

ALTHOUGH MEMBERS OF THE LINGUISTIC AND SPEECH RECOGNITION COMMUNITIES RECOGNIZE THE IMPORTANCE OF SUPRASEMENTALS (DURATION, INTENSITY, AND FUNDAMENTAL FREQUENCY OR PITCH) INUNDERSTANDING THE SPEECH CODE, THERE IS RELATIVELY LITTLE QUANTIFIABLE DATA AVAILABLE, PARTICULARLY ON PITCH. EMERSON & STERN ASSOCIATES HAS ALREADY DEVELOPED A BASIC APPROACH FOR RELIABLY EXTRACTING PITCH INFORMATION FROM VARI ...

ONE MAJOR LIMITATION TO PLANT VARIETY IMPROVEMENT VIA GENETIC ENGINEERING IS THE INABILITY TO SPECIFICALLY INACTIVATE GENES, EITHER PLANT GENES WHICH CONFER A DELETERIOUS PHENOTYPE, OR VIRAL GENES WHICH FUNCTION TO INITIATE THE INFECTION PROCESS. ADVANCED GENETIC SCIENCES, INC. PROPOSES TO EVALUATE A METHOD WHICH WILL ALLOW SUPPRESSION OF GENES IN A TISSUE-SPECIFIC AND REGULATED WAY. THE EXPERIMEN ...
