Abstract:RECENT EXPERIMENTS IN GREAT BRITAIN AND JAPAN DEMONSTRATED A HUNDRED-FOLD ENHANCEMENT OF CONVECTIVE AND BOILING HEAT TRANSFER BY THE APPLICATION OF DC OR LOW FREQUENCY ELECTRIC FIELS. ALSO, IN THE CASE OF BOILING HEAT TRANSFER, THE MEAN BUBBLE DETACHMENT TIME WAS REDUCED AND BOILING HYSTERESIS… more
Abstract:BIOCHEMICAL LIVER FUNCTION TESTS HAVE BEEN USED BY PHYSICIANS IN THE IDENTIFICATION AND MANGEMENT OF LIVER DESEASE. THESE STATIC TESTS INCLUDE MEASUREMENTS OF ALBUMIN, BILIRUBIN, ENZYMES AND PROTHROMBIN TIME. ALTHOUGH SUCH MEASURES PROVIDE INFORMATION ABOUT THE IMMEDIATE FUNCTIONAL STATE OF THE… more
Abstract:THE REFRACTIVE INDEX OF SCIENTIFIC MATERIALS IS OFTEN A VERY IMPORTANT PARAMETER. MANY CLASSICAL OR CONVENTIONAL TECHNIQUES FOR MEASURING INDEX OF MATERIALS REQUIRE COMPLICATED APPARATUS AND OFTEN REQUIRE SPECIAL SAMPLE PREPARATION, SUCH AS FABRICATING PRISMS OF THE MATERIAL. THIS MAY RENDER THE… more
Abstract:THIS PROJECT ADDRESSES THE NEED FOR EFFICIENT AND EFFECTIVE SUPPLY OF OXYGEN ON BOARD COMBAT AND TRANSPORT AIRCRAFT. THE PROPOSED EFFORT SPECIFICALLY INVOLVES THE DEVELOPMENT OF A CLOSED LOOP BLEED AIR DRIVEN CYCLE FOR A HYBRID OXYGEN SYSTEM FOR ON-BOARD OXYGEN GENERATION AND STORAGE. A CLOSED LOOP… more
Abstract:THE PROPOSED PROJECT ADDRESSES THE REPLACEMENT OF CFC-113 (FREON) AS A CLEANING AGENT, BOTH GENERALLY AND WITH SPECIFIC ATTENTION TO THE CLEANIUG OF METALS AND COMPOSITES. THE PHASE I WORK WILL PROVIDE A COMPREHENSIVE CHARACTERIZATION OF CLEANIUG REQUIREMENTS AND KNOWN METHODS. THE APPROACH IS… more
Abstract:APPLICATION OF SIMULATION AND MODELLING TO THE DESIGN OF SEMICONDUCTOR FABRICATION EQUIPMENT WILL REDUCE DEVELOPMENT TIME AND COSTS AND PROMOTE INNOVATION IN SEMICONDUCTOR MANUFACTURING. THIS PROJECT PROPOSES TO DEMONSTRATE THE FEASIBILITY OF AN INNOVATIVE SOFTWARE ENVIRONMENT FOR VIRTUAL… more
Abstract:An innovative pistonless impact mechanism for a seawater hydraulic rock drill is proposed. Compared to the current poppet-kicker port cycle, and poitentially higher impact energy. The proposed mechanism eliminates heavily loaded sliding elements, a chief problem in current mechanisms. The pistonless… more
Abstract:Creare is developing a novel technique for forming biaxially oriented thin and thick films of high temperature superconductor YBa(2)Cu(3)O(x) on non-lattice matched substrates. These films should display high critical current densities because they will avoid the weak link problem that occurs… more
Abstract:Creare is developing an innovative capillary-based evaporator component for direct cooling of advanced electronic modules and for interfacing with capillary pumped thermal management loops for spacecraft. A reentrant capillary structure design will increase by an order of magnitude the pumping… more
Abstract:We propose an innovative system for recovering waste heat from fighter aircraft. The system will tap the large quantities of available heat from the engine or airframe and use a Rankine cycle to generate useful power for the aircraft electrical systems. The innovative aspect of this power conversion… more
Abstract:Future multi-chip modules (MCMs) for radar and power electronics will need to operate at higher power densities. However, current power electronics modules are approaching operating limits due to the limited effectiveness of conventional techniques for heat removal via backside cooling. We propose… more
Abstract:The objective of the proposed project is to reduce by more than an order of magnitude the cost of reliable and contemination-free hermetically sealed compressors for long life Stirling and Pulse Tube Cryocoolers for spacecraft. State-of-the art compressors use unlubricated flexure bearings and… more
Abstract:Metalorganic chemical vapor deposition (MOCVD) of III-V semiconductor thin films will be improved through the development and application of unique gas injection hardware. The innovative hardware utilizes the vertical showerhead-type reactor configuration. It will enable for the first time detailed… more
Abstract:This proposal addresses the development of a miniature centrifugal compressor, a critical component for a low capacity, vibration free, long life cryocooler. Key features of the development include innovative fabrication methods to produce a unique rotor and impeller that allows the machine to… more
Abstract:AN INNOVATIVE WASTE HEAT POWERED DUPLEX STIRLING COOLER FOR HEAVY DUTY TRUCK REFRIGERATION IS PLANNED. THE MACHINE WILL EXPLOIT A PORTION OF THE WASTE HEAT ENERGY CONTAINED IN THE DIESEL ENGINE EXHAUST TO POWER THE STIRLING ENGINE COMPONENT OF THE REFRIGERATOR. A UNIQUE DESIGN PROVIDES HIGH… more
Abstract:AN INNOVATIVE HIGH PERFORMANCE WINDOW EDGE AND FRAME DESIGN WILL BE DEVELOPED. THE PROJECT OBJECTIVES ARE TO DEMONSTRATE THAT THE DESIGN IS REASIBLE FROM HEAT TRANSFER, STRUCTURAL, AND ECONOMIC PERSPECTIVES. ADDITIONALLY, THE DESIGN MUST BE COMPATIBLE WITH STANDARD ARCHITECTURAL AND BUILDING… more
Abstract:CURRENT SAMPLE SPINNERS FOR NMR SPECTROSCOPY ARE GENERALLY LIMITED IN ROTATIONAL SPEED TO ABOUT 10 KHZ. RESEARCHERS EXPECT TO DEMONSTRATE A SAMPLE SPINNER THAT IS CAPABLE OF STABLE OPERATION AT SPEEDS TO 40 KHZ. THE DEVICE WILL SIGNIFICANTLY IMPROVE THE RESOLUTION CAPABILITY OF SOLID STATE NMR BY… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
