A RESEARCH AND DEVELOPMENT PROGRAM IS PROPOSED WHICH WILL DETERMINE THE TECHNICAL FEASIBILITY OF AN INSTRUMENT DESIGNED TO PROVIDE THE CAPABILITY OF MEASURING THE CONCENTRATION OF OXY AND PEROXY FREE RADICALS IN COMBUSTION STUDIES. THE DETECTOR FOR THE INSTRUMENT IS BASED ON AN AMBIENT FREE RADICAL DETECTOR WHICH USES AN AMPLIFICATION CHAIN REACTION BETWEEN THE FREE RADICALS AND CO AND NO WHICHRES ...

THE PERFORMANCE OF LARGE-SCALE, LIGHTWEIGHT, SPACE-BASED MANIPULATORS IS CURRENTLY LIMITED BY THE AVAILABLE CONTROL SYSTEM TECHNOLOGIES. TO ACHIEVE HIGH PERFORMANCE WITH A SPACE-BASED MANIPULATOR, A CONTROL SYSTEM IS REQUIRED WHICH DOES NOT UNDERGO PERFORMANCE DEGRADATION DUE TO MANIPULATOR LINK FLEXURE. RESEARCH AND DEVELOPMENT IN THE AREA OF COMPLIANT MANIPULATOR CONTROL HAS BEEN HINDERED BY TWO ...

DENTAL ILLNESSES AND INJURIES OCCURRING IN THE FIELD ARE DIFFICULT TO TREAT WITHOUT A DENTAL CHAIR. WE HAVE DESIGNED A FIELD EXPEDIENT DENTAL CHAIR MADE OF COMPOSITE (PRIMARILY HONEYCOMB AND CARBONGRAPHITE FIBER) MATERIALS. THE CHAIR ALLOWS BOTH STAND-UP AND SIT DOWN DENTISTRY. THE CHAIR WEIGHS LESS THAN TEN LB., FOLDS TO A SMALL VOLUME, IS EASILY CLEANED AND IS RUGGED. ADDITIONALLY, THE DEVICE AL ...

BECAUSE OF THE COMPLEXITY OF GEOMETRY, LOADS AND MATERIAL SYSTEMS OF TURBINE BLADES, THE STRESS AND STRENGTH CHARACTERISTICS CAN NOT BE ACCURATELY PREDICTED BY EXISTING METHODS. THE COMPOSITE TURBINE BLADE STRENGTH CAPABILITIES ARE VERY MUCH DEPENDENT UPON THE CONSTITUENT MATERIAL PROPERTIES, PLY ORIENTATIONS AND STACKING SEQUENCE. THE OBJECTIVE OF THE PROPOSED STUDY IS TO DEVELOP A TECHNIQUE TO P ...

DURING THE DEVELOPMENT OF COMPLEX COMPUTER SYSTEMS, PERFORMANCE ENGINEERING TECHNIQUES ARE OFTEN NOT APPLIED OR ARE MISAPPLIED WHICH RESULTS IN SYSTEMS THAT DO NOT MEET THESPECIFIED PERFORMANCE CRITERIA OR MUST UNDERGO COSTLY REDESIGNS. AN INTEGRATED COMPUTER SYSTEM MODELING LANGUAGE OVERCOMES THE DEFICIENCIES OR TRADITIONAL ANALYTIC AND SIMULATION MODELING TOOLS BY EXPLOITING THE STRENGTHS FROM B ...

THE ESTIMATION OF THE COMPUTER CAPACITIES REQUIRED TO SUPPORT A MISSION ARE USUALLY THE SUBJECT OF MUCH DISCUSSION. ESTIMATES OF THE WORKLOAD AND OTHER PARAMETERS VARY GREATLY. THE REASON FOR THIS IS THAT MOST APPLICATIONS DO NOT FIT THE TRADITIONAL TIMING AND SIZING EFFORT. NONE OF THE THREE COMPONENTS (WORKLOAD, PERFORMANCE REQUIREMENTS AND ARCHITECTURE) IS USUALLY PRESENT. WE CONTEND THAT THE M ...

THE OPERATIONS OF A THERMODYNAMIC VENT SYSTEM (TVS) WILL BE INVESTIGATED WITH THE GOAL OF OPTIMIZING THE PERFORMANCE OF THE CRYOGENIC STORAGE SYSTEM FOR LONG TERM STORAGE. A TEN YEAR STORAGE LIFE IS THE ULTIMATE GOAL TO BE ACHIEVED. THE EFFECTS OF THE VENTED GAS ON IMPROVING THE PERFORMANCE OF A MULTILAYER INSULATION SYSTEM WILL BE OPTIMIZED BY VARIATION OF PARAMETERS. THE OBJECTIVE IS TO MINIMIZE ...
