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 ...

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 ...

THE MAJOR OBJECTIVE OF THE RESEARCH PROPOSED IS EVALUATION OF THE TECHNICAL FEASIBILITY OF THE NEW DESIGN FEATURES OF THE FILTER AND A COMPARISON OF ITS PERFORMANCE WITH CONVEN- TIONAL FILTERS IN TREATMENT OF WASTEWATERS. THE MAJOR SPECIFIC FEATURE OF THE FILTER IS A STONE-GRANULAR MEDIA BED WHICH IS EXPECTED TO PROVIDE A NON CLOGGING OPERATION, LONGER FILTRATION RUNS AND GREATER DIRT CAPACITY THA ...

THIS PROPOSAL WILL DEMONSTRATE (IN 2" TO 4" SIZE), A NOISE REUCING TRIM THAT CAN BE UTILIZED IN ROTARY CONTROL/ON-OFF BALL VALVES. THIS VALVE TRIM ADDRESSES NOISE AT THE SOURCE. THE BASIC DESIGN HAS A VARIABLE IMPEDENCE TRIM TO CAUSE A HIGH IMPEDENCE AT LOW ANGLES OF OPENING AND LOW IMPEDENCE (VERY LITTLE FLOW RESTRICTION) AT LARGE OPENING ANGLES. IT IS AN IDEAL VALVE FOR PRESSURIZATION/DE-PRESSUR ...

A MICROCLIMATOLOGICAL WEATHER STATION DESIGN IS PROPOSED WHICH INCORPORATES RESEARCH QUALITY INSTRUMENTS CAPABLE OF MEASURING HEAT FLUXES DIRECTLY. RECENT TECHNOLOGICAL ADVANCES HAVE ENABLED THESE INSTRUMENTS TO OPERATE IN REMOTE, LOW POWER, UNATTENDED APPLICATIONS. ULTRASONIC TECHNOLOGY IS USED TO MEASURE SENSIBLE AND LATENT HEAT FLUXES USING THE EDDY CORRELATION METHOD. THE WEATHER STATION IS DE ...
