THE KEY PROBLEM TO BE ADDRESSED IN PHASE I OF THIS PROJECT WILL BE TO DETERMINE THE FEASIBILITY OF A NOVEL POSITION MEASURING SYSTEM FOR A FAMILY OF COMPUTER CONTROLLED MACHINE TOOLS. THE MULTIPLE LASER MEASUREMENT SYSTEM (MLMS), WHICH FORMS THE BASIS OF THIS PROPOSAL, WILL MEASURE THE (X, Y, Z) POSITION OF THE CUTTING HEAD DIRECTLY AT RATES AND ACCURACIES SUFFICIENT FOR CLOSED LOOP POSITION CONTR ...

A PROJECT IS PROPOSED TO DEVELOP A BIOSENSOR FOR MEASURING PATHOGENIC MICROORGANISMS IN WATER BY MEASURING CHANGES IN CONDUCTANCE ACROSS MICROPOROUS, POLYCARBONATE MEMBRANE COATE WITH SPECIFIC ANTIBODIES. THE MEMBRANES WILL BE COATED WITH HYDROPHILIC POLYMERS USING PHOTOCHEMICAL COUPLING. ANTIBODIES SPECIFIC FOR THE ANALYTE WILL THEN BE COUPLED TO THE POLYMER-COATED MEMBRANES PRIMARILY IN THE PORE ...

A NEED EXISTS FOR THE DEVELOPMENT OF A LOW COST, RAPID IDENTIFICATION/MONITORING TEST KIT FOR POTENTIAL PATHOGENS IN FOOD PRODUCTS. A MAJOR INNOVATION WOULD INCREASE THE SCREENING OF DISEASE ORGANISMS WHILE MONITORING POTENTIAL PATHOGENS IN FOOD. THE PROPOSED RAPID EIA-BASED DIAGNOSTIC TEST KIT IS LIGHT-WEIGHT, EASY TO USE, ECONOMICAL AND CAN BEADAPTED TO A VARIETY OF SITUATIONS AND SPECIMENS. THI ...

THE US MARINE CORPS HAS A DIRECT NEED TO MAINTAIN THE HEALTH AND FUNCTIONAL EFFECTIVENESS OF ITS PERSONNEL AGAINST A VARIETY OF DANGEROUS BIOLOGICAL AGENTS. METHODS TO DETECT THESE AGENTS IN ENVIRONMENTAL OR FIELD SAMPLES MUST BE DEVELOPED FOR USE IN THE NBC LABORATORY PROGRAM. THE PROPOSED NOVEL RAPID DETECTION SYSTEM CAN BE USED TO MONITOR BIOLOGICAL AGENTS IN FIELD ENVIRONMENTAL SAMPLES. THE IN ...

TO ENSURE RELIABLE PRODUCTION OF CARTRIDGE CASINGS, CRITICAL DIMENSIONS, SUCH AS THE PLACEMENT AND SIZE OF THE PRIMER CUP AND VENT HOLE, MUST BE ACCURATELY MAINTAINED. CURRENTLY, THERE IS NO ABILITY TO MEASURE CRITICAL DIMENSIONS OF THE PRIMER CUP DURING THE PRODUCTION OF THE 5.56MM CARTRIDGE CASING. IN THIS PROPOSAL, CYBER-OPTICS DESCRIBES A PROGRAM TO DEVELOP A PROTOTYPE INSPECTION STATION TO ME ...

FUTURE MILITARY AVIONICS SYSTEMS WILL REQUIRE AT LEAST AN ORDER OF MAGNITUDE IMPROVEMENT IN MEAN TIME BETWEEN CRITICAL FAILURES. TO ACHIEVE THIS GOAL INNOVATIVE FAIL-SAFE FAULT-TOLERANT ELECTRONIC SYSTEM DESIGN CONCEPTS WILL BE NEEDED. THE APPROACH PROPOSED BY DAINA WILL BE BASED ON THE USE OF EXTERNAL ENVIRONMENT DATA, BUILT-IN RELIABILITY MODEL, ADAPTIVE STATISTICAL SYSTEM STATE AND PARAMETER ES ...

WE PROPOSE TO ASSESS THE FEASIBILITY OF AN AUTOMATED MEANS OF DETERMINING WHEN TO INSEMINATE DAIRY CATTLE IN ORDER TO IMPROVE REPRODUCTIVE PERFORMANCE. POOR REPRODUCTIVE PERFORMANCE IS THE MOST COSTLY MANAGEMENT PROBLEM DAIRY PRODUCERS FACE, AND FAILURE TO DETERMINE THE PROPER TIME TO ARTIFICIALLY INSEMINATE DAIRY CATTLE IS THE MAJOR CAUSE OF POOR REPRODUCTIVE PERFORMANCE. IN THE PROPOSED EFFORT W ...

NITROGEN IS A LIMITED MINERAL NUTRIENT IN MANY AGRONOMIC SYSTEMS. LEGUMINOUS CROPS SUCH AS SOYBEAN AND ALFALFA USE BOTH SOIL NITROGEN AND, WHEN SUITABLE STRAINS OF THE NITROGEN-FIXING MICROSYMBIONTS BRADYRHIZOBIUM AND RHIZOBIUM ARE AVAILABLE, ATMOSPHERIC NITROGEN. IT HAS BEEN ESTIMATED THAT THE 50 MILLION HECARES OF CULTIVATED GRAIN AND FORAGE LEGUMES IN THE UNITED STATES OBTAINED MORE THAN 6 MILL ...
