Abstract:A need exists for a cost effective means for fabricating high- temperature rhenium structures having good mechanical properties. A program is proposed to demonstrate the merits of fused salt deposition of rhenium on various refractory substrates using current manipulating techniques such as pulsed… more
Abstract:Multiphase fluid flows involving free surface fluids can be found in many space transportation and propulsion systems such as injector atomization in SSME combustors, cavitation in liquid rocket pump operations, handling of cryogenic fluids in a micro- gravity environment and the operation of… more
Abstract:This project aims towards an initial "Formal Methods Inter-face,, frame- work which will provide interface in three senses: * between the engineer and formal methods tools; * to support interworking of diverse tools which implement a ide range of formal approaches; * between the formal tools and… more
Abstract:This proposal presents the concept of a User Tailorable Interface Development System (UTIDS) to facilitate the ability of users to dynamically specify the information required for their mission control tasks and minimize the effort required to tailor the interface to be adaptable for multimission… more
Abstract:Huntsville Sciences Corporation (HSC) proposes to develop a new and innovative approach for predicting the pore pressures and structural behavior of a thermochemically decomposing composite ablator material like those commonly used to insulate rocket nozzles. The proposed method uses a… more
Abstract:Fast Fourier transformers (FFFs) are used extensively in military and commercial applications. There is a constant demand for faster and more accurate FFTS. RNS (Residue Number System) based FFTs are candidates to provide these improvements, however techniques for efficient implementation of RNS… more
Abstract:The objectives of this Phase I program is to demonstrate the feasibility of a new class of monolithic solid state quantum well lasers for the mid-infrared. The concept is based on the use of a novel electron Fabry-Perot interference effect which achieves population inversion by free electron… more
Abstract:The recent development of ratation and translation invariant Synthetic Discriminant Filters (SDFs)the image processing ability of optical correlators. Distinguishing features are detectable and recoobject regardless of image orientation or magnification. Extension to medical imagery is a natural… more
Abstract:The objective of this proposed effort is to design a compact infrared zoom lens suitable for use in guided munitions. The continuously variable zoom of the lens offers significant operational performance benefits to weapon systems using switchable FOV optics. Oetc will design a zoom lens that… more
Abstract:Physitron proposes development of an x-ray/gamma-ray telescope that can be used for treaty verification and compliance testing. In particular, the x-ray/gamma-ray telescope can be mounted in the Open Skies Treaty aircraft to provide a capability of detect, characterize and identify nuclear weapons… more
Abstract:The Physitron team (Physitron, Vanderbilt University, and Harris Semiconductor) will demonstrate the ability to integrate high quality ultra thin film diamond on silicon semiconductor as insulating dielectric on metal-insulator-semiconductor (MIS) capacitor structures. Successful completion of… more
Abstract:We propose the development of an innovative new type of hybrid diffractive-refractive optical element, called a staircase lens. This new type of lens has many advantages over both traditional refractive lenses and common diffractive elements. The staircase lens is an excellent tool to use for… more
Abstract:A cost efficient aerothermal design tool is required for redesign for the Holloman rocket sled TPS for operating conditions in excess of Mach 10. Current hardware was designed with peak velocities at Mach 8. The proposed program is to develop a set of analytical software products which will both… more
Abstract:Despite the improvements in linkage techniques introduced by PRC and mircrosatellites,genotyping remains very technical, time consuming and expensive. Multiplexing the analysis is one wayto reduce the cost and improve the efficiency. We will develop, produce and distribute microsatellitemarkers… more
Abstract:ResearchSouth, Inc. proposes to develop methodology and preliminary design computer software for the analysis of stiffened composite panels used in designing hot structures on hypersonic vehicles. Phase I of the development will investigate the following major areas of the preliminary design of… 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.
