Abstract:The primary objective of this proposed work is to develop a method of producing integrally stiffened, complex shaped monolithic structural components in high strength aluminum alloys at a lower cost and lighter weight than equivalent conventional built-up assemblies. In Phase I the feasibility of… more
Abstract:THE DEVELOPMENT OF COLD ELECTRON EMITTER TECHNOLOGY HAS THE POTENTIAL FOR BROADLY IMPACTING THE RAPIDLY GROWING AREA OF ELECTRON SPECTROSCOPY. COMMERCIALLY AVAILABLE INSTRUMENTATION SUCH AS AUGER SPECTROMETERS TYPICALLY EMPLOY THERMIONIC ELECTRON SOURCES WHICH RESTRICT THEIR SCOPE OF USE THROUGH… more
Abstract:Chemical vapor deposition (CVD) of copper for vias and interconnects is critical to manufacture of next generation high speed ULSI devices and has been extensively investigated over the last few years. Although considerable progress has been made commercialization of this technology is currently… more
Abstract:Sensors and electronics will become increasingly pervassive as weight, fuel efficiency, cost and emissions requirements put increasing demands on vehicle technology. The development of high temperture, integrated sensors and electronics is necessary to cost-effectively address both civilian and… more
Abstract:As we approach the 21st century, increases in traffic accidents, the creeping paralysis of traffic congestion, and global environmental pollution have focused attention on reconciling the internal combustion engine (ICE) powered vehicle with the needs of the greater society. The solutions to these… more
Abstract:All future combustion and electric powered automobiles will be equipped with sensors directly interfaced with control electronics. The control and power electronics for combustion engines will have to cope with high temperatures and adverse environments. Hybrid and electric vehicles require new… more
Abstract:NASA SPACE SCIENTISTS TEND TO USE INTEGRATED DATA OF MULTIPLE TYPES. FOR EXAMPLE, THE OBSERVATIONS COLLECTED BY THE EXOSAT SATELLITE ARE MADE UP OF DATABASE ROWS, IMAGES, SPREADSHEETS (SPECTRA, LIGHTCURVES), TEXT INDEXES, ETC. ALSO, THE DIFFERENT DATA TYPES COME FROM HETEROGENEOUS MANAGEMENT SYSTEMS… more
Abstract:This project will develop a computer-assisted consultation system for clinical radiologists in thedetection of lung nodules (cancer) on chest radiographs. An automated screening of digital chestradiographs can be further developed when this system is fully tested in various clinical settings.… more
Abstract:This project will develop a computer-assisted consultation system for clinical radiologists in theclassification of benign and malignant (cancer) calcifications on mammograms. An automated screeningof digital mammograms can be further developed when this system is fully tested in various… more
Abstract:An implantable, multi-channel epidural electrode for spinal cord stimulation (SCS) is to bedeveloped which will have improved installation and operational features compared to the current stateof the art. The most common applications for SCS is the treatment of chronic, intractable pain, andvascular… more
Abstract:Solid Free Forming of monolith and uniform discrete reinforced materials has been demonstrated by fused deposition of heavily loaded slurries. In this program we will extend the fused deposition process to functional gradient material. The composition of material deposited will be controlled by 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.
