Abstract:This proposal is concerned with the accurate computer simulation of compressible transonic and supersonic flows. It explores the feasibility of developing a Computational Fluid Dynamics (CFD) code based on the p-version of the finite element method, which alleviates some of the inherent limitations… more
Abstract:The proposed SBIR research targets the development of a state-of the-art- optical heat transfer sensor for unsteady measurement in modern turbomachinery. The operational principal of the sensor is based on the UV-induced fluoresence emission of rare-earth ion doped thermographic phosphors (TGP).… more
Abstract:Airborne radars are potentially vulnerable to ground bounce jamming, where the jammer illuminates terrain in the radar's search beam. This poses a difficult ECCM problem, since the scattered jamming arrives from a large region with a spread in both delays and Doppler shifts. The radar must suppress… more
Abstract:The overall objective of this effort is to develop an innovative approach and defined process which will produce an ultra-miniature (small diameter) formless coil capable of withstanding a critical application environment. A key element of the process will be development of an adhesive specifically… more
Abstract:A proposed technical approach and Phase I work plan is given for developing instrumentation capable of measuring the lateral storage (elastic) and loss moduli of parallel optical fibers under lateral line contact loads representing conditions found in precision parallel wound high speed payout… more
Abstract:An innovative method to improve both the optical and mechanical properties of polarization maintaining fiber is proposed. The method uses magnetic annealing to improve the extinction ratio, optical loss, bend insensitivity and the tensile strength. The phase I effort will demonstrate proof of the… more
Abstract:The traditional modulation techniques employed on satellite links are based on the second-order spectrum of the modulation wave form. In this proposal, we explore the utility and performance of modulation schemes based on higher-order cumulant sequences and the associated frequency-domain… more
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
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.
