The Phase I Trusselator effort successfully demonstrated… more
Abstract:TUI proposes a novel process to produce 3d printer feedstock filament out of scrap ABS on the ISS. Currently the plastic filament materials that most 3d printers use are produced with screw-based extruders that are fundamentally designed for high volume terrestrial production from uniformly… more
Abstract:Cryogenic soft X-ray detectors are enabling new analytical capabilities for science, engineering, materials characterization, and time-resolved studies. X-ray microcalorimeter detectors are increasingly being used at synchrotron light sources, with scanning electron microscopes and other analytical… more
Abstract:The technological systems on which today's war-fighters depend, reflecting today's society, are vulnerable to the effects of sudden high-energy events from our Sun. Because the propagation speed for sudden increases in X-rays from a solar flare is the speed of light, it is necessary to… more
Abstract:ABSTRACT: Thermospheric densities are critical in determining orbital drag for providing collision avoidance warnings for manned and unmanned spaceflight, accurately cataloging orbiting objects, predicting reentry times, and estimating satellite lifetimes, on-board fuel requirements, and attitude… more
Abstract:ABSTRACT: Coordinate Registration (CR) of OTHR targets requires accurate real-time ionospheric modeling coupled with HF propagation calculations to convert radar-measured target signal delays and beam steers to geographical position. Our team is the developer of one of the most sophisticated… more
Abstract:ABSTRACT: Chrome plating is used extensively for aerospace and industrial applications because it is wear resistant, corrosion resistant, has a good surface finish and has good adhesion. Aircraft use chrome plating on landing gear components because of these characteristics. However these coatings… more
Abstract:High-value bearings are a critical part of the safety, reliability, cost and performance of modern aircraft. A typical passenger jet will have 100 to 175 high-valve bearings costing from $2,500 to $50,000 each for a total aircraft cost of $300,000 to $600,000. All gas turbine engine bearings are… 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.
