IN THIS PROJECT ANALYTICAL AND EXPERIMENTAL RESEARCH WILL BECONDUCTED ON CENTRIFUGAL INFILTRATION OF CARBON FIBER PREFORMS BY MOLTEN ALUMINUM ALLOYS TO FORM TUBES OF ALUMINUM-CARBON FIBER COMPOSITES. MODELING WILL BE DONE TO DERIVE THE OPTIMUM SURFACE TREATMENT OF FIBER PREFORM AND INFILTRATION CONDITIONS. A FEW SELECTED EXPERIMENTS WILL BECONDUCTED TO CENTRIFUGALLY INFILTRATE CARBON FIBER PREFORM ...

COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

THE CONTROL OF TERMITES IS A MAJOR PROBLEM IN THE UNITED STATES. THE PRINCIPAL METHODS OF WOOD PRESERVATION ARE INORGANIC ARSENIC COMPOUNDS, PENTACHLOROPHENOL AND CREOSOTE. THESE AGENTS APPEAR TO BE ENVIRONMENTALLY HAZARDOUS, INCLUDING CARCINOGENIC. PRELIMINARY RESEARCH HASREVEALED THAT THE HEARTWOOD AND LEAF COMPONENTS OF THE JUNIPERS (JUNIPERUS) HAVE VERY HIGH TERMITICIDAL ACTIVITIES. THE PROPOS ...

THERE IS A LARGE POTENTIAL MARKET FOR BIOSENSORS IN THE CLINICAL AND HEALTH CARE FIELDS AND FOR INDUSTRIAL PROCESS MONITORING. OFTEN BIO-SENSORS REQUIRE EXPENSIVE EQUIPMENT AND PROCEDURES THAT ARE CONFINED TO THE SKILLED OPERATOR ANDTHUS ARE UNSUITABLE FOR MANY PURPOSES OUTSIDE THE ANALYTICALLABORATORY. A NOVEL SIGNAL TRANSDUCTION METHOD IS DESCRIBEDTHAT COULD LEAD TO SIMPLIFIED MONOCLONAL ANTIBOD ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...

THE PROPOSED RESEARCH ADDRESSES THE DEVELOPMENT OF A COMPUTER-BASED MODEL TO PERFORM CONCURRENT LIFE-CYCLE ANALYSIS FOR THE DESIGN OF ADVANCED LAUNCH SYSTEM CONCEPTS. THE MOTIVATION FOR THIS EFFORT STEMS FROM THE HIGH COST OF MANUFACTURING, OPERATING, AND SUPPORTING CURRENT EARTH-TO-ORBIT VEHICLE DESIGNS. UNITED STATES ACCESS TO SPACE HAS BEEN SEVERELY LIMITED AS A RESULT OF THE ANALYTICAL DESIGN ...

THE DEVELOPMENT OF INTEGRATED DESIGN AND MANUFACTURING SYSTEMS IS WIDELY RECOGNIZED AS A CRITICAL COMPONENT IN THE EFFORT TO IMPROVE THE COMPETITIVE POSTURE OF AMERICAN INDUSTRIES. A KEY TO THE SUCCESS OF THESE COMPUTER INTEGRATED MANUFACTURING SYSTEMS LIES IN THE ROBUSTNESS OF THE INFORMATION INTEGRATION SUPPORTED BY THE SYSTEMS. HOWEVER, THE INDIVIDUAL METHODS AVAILABLE TO SUPPORT THE DEFINITION ...

IT IS A RECOGNIZED PROBLEM THAT CURRENT COMPUTER AIDED DESIGN (CAD) AND COMPUTER AIDED ENGINEERING (CAE) INTERFACES(1) LIMIT PRODUCTIVITY OF HUMAN DRAFTSPERSONS, (2) DENY CONCEPT SUPPORT TO PRODUCT DEFINERS, AND (3) INHIBIT USE OF THESE SYSTEMS FOR DELIVERY OF KNOWLEDGE BASED CONCURRENT ENGINEERING SUPPORT. THESE PROBLEMS LIMIT INITIATIVES TO BOTH PRODUCE BETTER FIRST DESIGNS AND TO REDUCE THE PRO ...

AT PRESENT GLUCOSE IS COMMERCIALLY REDUCED TO SORBITOL BUT THE OPERATING CONDITIONS USED (HIGH TEMPERATURE AND HIGH HYDROGEN GAS PRESSURE) ARE UNDESIRABLE AND DANGEROUS. AN ALTERNATIVE APPROACH IS THE PAIRED ELECTROCHEMICAL SYNTHESISOF SORBITOL AND GLUCONIC ACID IN AQUEOUS SOLUTIONS AT AMBIENT TEMPERATURE AND ATMOSPHERIC PRESSURE. HOWEVER, A MAJOR DRAWBACK TO THIS APPROACH AT PRESENT IS THE NEED F ...

THIS PROPOSAL SPECIFICALLY ADDRESSES "KNOWLEDGE REPRESENTATION" BY PERFORMING RESEARCH INTO "SOFTWARE DEVICES FOR CAPTURING KNOWLEDGE FROM A REAL-TIME CONTEXT ANDCONVERTING IT TO AN EFFECTIVE COMPUTATIONAL FORM". THE PROPOSED ARTIFICIAL NEURAL NETWORK LEARNING PARADIGM OPERATES ON SPATIOTEMPORAL PATTERNS AND HAS THE FOLLOWING CHARACTERISTICS: (1) OPERATES CONTINUOUSLY WITHOUT AD HOC SUPERVISION; ( ...
