ACCURATE NUMERICAL SIMULATIONS SHOULD PROVIDE A POWERFUL TOOL FOR PLANNING MEANINGFUL EXPERIMENTS ON FUTURE SPACE MISSIONS. A COMPREHENSIVE, GENERAL-PURPOSE TOOL OR SIMULATION OF SPACE-BASED MATERIALS PROCESSING PROBLEMS WILLBE DEVELOPED USING THE NEKTON SPECTRAL-ELEMENT, GENERAL-GEOMETRY FLOW CODE. THIS TOOL WILL PERMIT THE OPTIMIZATION OF CONFIGURATIONS AND PARAMETERS REQUIRED FOR SPACE APPLICAT ...

PARALLEL PROCESSING OFFERS NEW AND EXCITING POSSIBILITIES IN THE AREA OF COMPUTATIONAL FLUID DYNAMICS (CFD). THIS PROJECT DEVELOPS A GENERAL-PURPOSE PARALLEL SOFTWARE PACKAGE FOR PERFORMING LARGE SCALE FLUID DYNAMICS AND HEAT TRANSFER CALCULATIONS OF INTEREST TO INDUSTRY AND TO GOVERNMENT LABORATORIES. THE RESEARCH ADDRESSES SEVERAL DISCIPLINES CRUCIAL TO EFFECTIVE UTILIZATION OF MODERN COMPUTER A ...

RECENTLY, RESISTANCE TO ANTHELMINTICS HAS EMERGED AS THE MOST IMPORTANT PROBLEM CONFRONTING THECONTROL OF PARASITIC NEMATODES OF RUMINANTS. RESISTANCE IN PARASITES OF OTHER ECONOMICALLY SIGNIFICANT ANIMALS HAS ALSO BEEN REPORTED AND THERE CAN BE LITTLE DOUBT THAT THE INCIDENCE OF RESISTANCE WILL INCREASE AND WILL ALSO EVENTUALLY APPEAR IN MEDICALLY IMPORTANT PARASITES OF MAN. THE IMPACT OF RESISTA ...

THIS PROPOSAL RESPONDS TO THE STATED GOALS OF DARPA SBIR TOPIC 91-181 BY PROPOSING THREE NOVEL APPROACHES: (A) DEVELOP RAPID MODELING TECHNOLOGY (RMT) TOOLS FOR DESIGN, PLANNING, AND DECISION SUPPORT OF SEMICONDUCTOR FACTORIES, (B) RECOGNIZING THE MULTIPRODUCT COMPLEXITY IN SEMICONDUCTOR MANUFACTURING, DEVELOP SCHEDULING TOOLS BASED ON LAGRANGIAN RELAXATION TECHNIQUES WITH SIGNIFICANT POTENTIAL AD ...

MAJOR DECISIONS IN MANUFACTURING COMPANIES ARE BEING MADE WITH INADEQUATE DECISION SUPPORT TOOLS. TRADITIONAL COST ANALYSIS CONTAINS ASSUMPTIONS THAT EVENTUALLY LEAD TO INCORRECT DECISIONS. COST ACCOUNTING DOES NOT INCLUDE ADEQUATE PRODUCTION MODELS AND ASSUMES THAT COSTS ARE LINEAR. COST ALLOCATION RULES USED IN THESE MODELS MAY DISRTORT THE PERCEIVED PART COSTS AND LEAD TO INCORRECT DECISIONS. W ...

SIGNIFICANT PROGRESS HAS BEEN ACHIEVED IN THE DEVELOPMENT OF NEW EQUIPMENT AND MODIFICATION OF EXISTING FILAMENT WINDING EQUIPMENT TO ACCOMMODATE IN SITU FABRICATION OF THERMOPLASTIC PARTS. ADVANTAGES OF ON-LINE CONSOLIDATION THROUGH FIBER PLACEMENT ARE CONTINUOUS WINDING OF THICK-WALLED PARTS, ELIMINATION OF OVEN OR AUTOCLAVING CURING, LOW VOID CONTENT, AND LESS MATERIAL SCRAP. ONE OF THE CHALLEN ...

A KEY AUTOMATION PROBLEM IN THE SEMICONDUCTOR MANUFACTURING AREA IS THE EFFICIENT HIGH-YIELD FABRICATION OF SEMICONDUCTOR CIRCUITS. PLASMA ETCHING IS THE KEY PROCESS BY WHICH DESIRED CIRCUITS ARE PATTERNED ON A SEMICONDUCTOR WAFER. AS PATTERN GEOMETRIES BECOME MORE INTRICATE IN THE SUBMICRON RANGE, ETCHING PROCESSES BECOME MORE COMPLEX. BECAUSE THE INTRACTABLE. SEMICONDUCTOR MANUFACTURERS TYPICALL ...

THE GOAL OF THIS PROJECT IS TO DEVELOP A FORTY MINUTE INTERACTIVE VIDEO DISC FOR MEDICAL STUDENTS IN THEIR PRECLINICAL YEARS TO FOCUS ON THE ETIOLOGY OF HIV; DIAGNOSIS OF AIDS-ASSOCIATED DISEASES; CARE OF PERSONS WITH AIDS AND RELATED DISORDERS; PREVENTION OF HIV INFECTION; AND THE ETHICAL, LEGAL AND ECONOMIC CONCERNS RELATED TO THE DISEASE. SPECIFIC ISSUES TO BE DISCUSSED INCLUDE PROFESSIONAL RES ...

BREAST CANCER, CURRENTLY THE SECOND LEADING CAUSE OF DEATH IN WOMEN IN THE UNITED STATES, IS CLEARLY A PUBLIC HEALTH PROBLEM. BECAUSE IT IS NOT YET KNOWN HOW TO PREVENT BREAST CANCER FROM OCCURING, THE MOST EFFECTIVE STRATEGY IS EARLY DETECTION. WHILE NUMEROUS EDUCATION AND BEHAVIOR CHANGE CAMPAIGNS HAVE BEEN CONDUCTED TO ENCOURAGE WOMEN TO PRACTICE METHODS OF EARLY DETECTION, NO MORE THAN 40 PERC ...
