Abstract:Multichip modules (MCMs) have allowed the microelectronics industry to produce relatively small, highly-integrated circuitry with performances that far exceeds that of other packaging technologies such as separately packaged ICs soldered onto a printed circuit board. Bare dies are packaged together… more
Abstract:OTI proposes to identify, research, prioritize, select and prove concept feasibility of techniques for testing concurrent, real-time, distributed, large-scale software during Phase I. A prototype proof-of-principle will be build during Phase II of this program by integrating test techniques selected… more
Abstract:CURRENTLY, NO SINGLE MATERIAL SATISFIES ALL THE DESIGN REQUIREMENTS FOR PLASMA FACING COMPONENTS IN MAGNETIC FUSION DEVICES. THEREFORE COMPLEX DESIGNS HAVE BEEN PROPOSED AND TESTED, BUT OPERATION OF THE DEVICES IS STILL LIMITED. INNOVATIVE TECHNIQUES ARE PLANNED IN THIS PROJECT TO FABRICATE… more
Abstract:Bone marrow sampling, a term which includes both biopsy and aspiration, is used in thediagnosis and evaluation of many diseases. These include malignant conditions, especially leukemias,lymphomas and myelomas, disorders of blood and lymphoid cell production, and many other illnesses.Repeated… more
Abstract:The rise of launch clouds to stabilization is forced by an altitude varying distribution of momention and buoyancy (temperature). In most of the plume, the temperature excess over that of the atmosphere is large and the buoyant force accelerates the launch products to "high" altitudes. The… more
Abstract:SECA, Inc. with the assistance of AMROC, Inc. proposes to develop the methodology required to analytically predict the combustion efficiency of operational hybrid rocket motors from basic test data characteristic of the fuel employed. Such methodology is not currently available, and it is essential… more
Abstract:With all the uncertainties in complex Distribute Hybrid Systems (DHS), one key probelm is the definition of a reasonable set of tests (and tools) that will evaluate both the extrmees and the nominal behaviors associated with real-world situations. This general lack of confidence for AI components… more
Abstract:Tomorrowtools proposes to develop a transportable virtual reality (VR) training station which will be fully interactive with a remote VR training simulator/host computer. The proposed device will link in realtime a 5 ounce, 96 kilopixel video headset and a head position tracking device to a 128… more
Abstract:Of the risk factors associated with coronary artery disease, the most important is inheriteddyslipoproteinemia, including elevated LDL. We will develop a nationwide network of referrallaboratories for comprehensive lipoprotein testing based upon the VAP-II procedure. The goal is toprovide a single… more
Abstract:This project will provide a low cost method of continuously assuring that the weld filler wire required by qualified Welding Procedure Specifications has been used. The method will be based on continuous eddy current testing. The weldments will have the required resistance to welding and service… more
Abstract:THE PERFORMANCE CAPABILITY OF EMERGENCY ESCAPE SEATS IS LIMITED AT HIGH AIRPLANE SPEEDS AND LOW ALTITUDES BY THE OCCURRENCE OF WINDBLAST INJURIES. CURRENT STATE-OF-THE-ART SEATS, AT SPEEDS OF 600 KEAS EXPOSE THE OCCUPANT TO FORCES BEYOND PHYSICALLY TOLERABLE LIMITS, DUE TO LARGE DRAG FORCES ACTING… more
Abstract:Development of combined Air-Turbo-Rocket(ATC/Scramjet component technology suitable for numerous USAF propulsion missions is proposed. Preliminary component design will focus on attaining fully throttleable boost and sustain thrust, vehicle speeds from Mach 0 to 8, and range as required. Activities… more
Abstract:CARDIAC SURGERY OFTEN INVOLVES REPLACEMENT OF THE NATURAL AORTIC VALVE, OR THE AORTIC ROOT AND ASCENDING AORTA, OR BOTH, WITH THE CORRESPONDING PROSTHESES. BLOOD FLOW THROUGH THE AORTIC VALVE IS INFLUENCED THE THE CORRESPONDING FLOW FIELD IN, AND AROUND, THE AORTIC ROOT. THERE EXISTS THE NEED FOR A… more
Abstract:Water is an attractive halon-alternative extinguishing agent for fire suppression. This SBIR proposes to develop a twin-fluid water nozzle that produces spray with a Sauter Mean Diameter less than 20 microns, and discharges water droplets at high velocities (equivalent to 500 m/s) to enhance… more
Abstract:Cavitation is believed to cause damage to tilting disk mitral mechanical heart valves (MHVs). Previous studies have indicated that this phenomenon may be dominant during MHV closure. The "squeeze-flow" field between the closing occluder and valve housing, water hammer pulse at closure and the… more
Abstract:A novel wave rotor topping cycle, which incorporates a Rich burn- Quick mix-Lean burn (RQL) combustor integrally coupled with a wave rotor, is proposed in this SBIR project. This cycle has the potential of significantly lower NOx levels than demonstrated RQL combustors, plus higher engine efficiency… more
Abstract:IN THE FIELD OF COMPUTATIONAL FLUID DYNAMICS (CFD), A MULTIZONAL APPROACH GREATLY SIMPLIFIES THE RESOLUTION OF COMPLEX GEOMETRICAL DETAILS AND THE APPLICATION OF DIFFERENT FLOW PHYSICS IN DIFFERENT ZONES OF THE FLOW DOMAIN. PREVIOUS MULTI-ZONAL PATCHED AND OVERLAPPED APPROACHES SUFFERED FROM ONE OR… 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.
