Abstract:There is a critical need for the development of high temperature, corrosion resistant, low weight, and low cost recuperators to increase the efficiency of advanced gas turbine engines. The temperature requirements dictate the use of ceramic materials, and the material choice is silicon carbide… more
Abstract:This project will develop a complete, practical, cost effective high density electro-physiology recfor general neuroscience and biological neural network research. This project involves design of 1)on-animal electronics; 2) computer interfaces; and 3) software for storing acquired data,… more
Abstract:It is estimated that by the year 2000, 25 million people will be diagnosed with osteoporosis and thpatients at risk for spine, hip and wrist fractures will be substantially greater. Clearly, osteoporimportance and novel approaches to therapy are required. The long-term objective of this work is… more
Abstract:Osteoarthritis, the major degenerative disease of the weight bearing joint surfaces, is present inof the population 50 years of age and older, and it is estimated that more than 37 million suffer frU.S. economy more than $8.6 billion/year. There is a need to develop new therapeutic approaches… more
Abstract:Even though most fractures heal without significant medical complications, they result, nonethelessamount of physical disability, loss of industrial productivity, and represent a major national healtThis has led to a continued search for a methodology which can be utilized to stimulate the… more
Abstract:WE PROPOSE TO DEVELOP A PORTABLE MONITORING SYSTEM CAPABLE OF DETECTING TRACE QUANTITIES OF RADIONUCLIDES IN SOILS USING A HIGH RESOLUTION CADMIUM TELLURIDE ARRAY DETECTOR AND A RUGGED MULTICHANNEL DATA LOGGER. THE PROPOSED MONITORING SYSTEM BUILDS UPON THE DESIGN OF A SIMPLE MONITOR DEVELOPED TO… more
Abstract:Design of a novel digital signal processing (DSP) radiometer system is proposed, which combines a low-noise, high stability radio frequency (RF) down-converter, a high speed digitizer with a deep buffer memory, and a personal computer running an innovative DSP software known as X-Midas. X-Midas… more
Abstract:Propulsion system components are being exposed to increased thermal and aerodynamic loads. Active stabilization of these components is considered one of the key technologies required to enhance the oeprability of gas turbine engines. Recently there have been numerous successful demonstration 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.
