Abstract:When loading nitrogen tetroxide before launching the space shuttle, fugitive N2O4 is absorbed into caustic solutions in a two stage scrubber solution. The second stage of the scrubber has sodium sulfite added to the alkaline scrubbing solution to act as an oxidant scavenger, to improve scrubbing… more
Abstract:THE PROVISION OF ACCEPTABLE LEVELS OF OCCUPANT COMFORT IN AN ELECTRIC VEHICLE (EV) ADDS CONSIDERABLY TO THE LOAD ON THE BATTERY SYSTEM. BATTERIES BARELY STORE ENOUGH ENERGY TO PROVIDE AN ADEQUATE RANGE WITHOUT ANY AUXILIARY LOAD. THE ADDITION OF MAJOR POWER-CONSUMING OPTIONS, SUCH AS AIR… more
Abstract:The intent is to create an artificial intelligence software system which accurately predicts chemical toxicity. The system will use a neural network to recognize patterns and correlation between chemical structure/substructures, physicochemical properties, and toxicologic/carcinogenic findings. An… more
Abstract:Increasing evidence suggests that chemically-induced cell proliferation plays a role in carcinogenesis. The complex relationships between chemically-induced mutations, cytotoxicity, cell proliferation and carcinogenesis are important considerations in setting doses for cancer bioassays, classifying… more
Abstract:This proposal is for the development of an optically activated high voltage semiconductor switch device capable of switching loads on and off within nanoseconds or picoseconds. A device of this type would not be possible using the existing limitations imposed by the limited knowledge on the… more
Abstract:THE PROPERTIES OF CLOSED OR ALMOST-CLOSED SURFACES WITH BETA-EMITTING WALLS WILL BE STUDIED BY MEANS OF POWERFUL MONTE CARLO TRANSPORT MODELS. POSSIBLE USE OF THE ENCLOSURES IN DELIVERING AREALLY UNIFORM SURFACE DOSES TO TARGETS THAT ARE EITHER WITHIN THE ENCLOSURES OR THAT ARE EXTERNALLY APPOSED TO… more
Abstract:We propose research into the design of a Real-Time Distributed Module Interconnection Framework (RTD-MIF) system for use in the development of distributed, real-time computer software. Real-Time capabilities will include abnormal event processing, RT/FT events and on-line system monitoring and… more
Abstract:THE OVERALL OBJECTIVE IS TO DEVELOP AN INNOVATIVE EDUCATIONAL VIDEOTAPE WHICH DESCRIBES HOW DRUGS OF ABUSE ACTIN THE BRAIN. THE VIDEO WILL HAVE CREATIVE YET SCIENTIFICALLY ACCURATE ANIMATION AND A SCRIPT WHICH INTRODUCES NEUROSCIENCE TO ADOLESCENTS. SPECIFICAIMS FOR PHASE I ARE: 1) TO DEVELOP THE… more
Abstract:SOFTWARE ENGINEERING IS A COMPOSITE OF DATA AND RULES ABOUT HOW THOSE DATA ARE COMPOSED, PRESENTED TO VARIOUS USERS, AND TRANSFORMED AS SOFTWARE DEVELOPMENT PROCEEDS. AN APPROPRIATE COMPUTER-AIDED SOFTWARE ENGINEERING (CASE) EINVIRONMENT (SEE) MUST EASILY HANDLE DATA AND RULES. CURRENTLY AVAILABLE… more
Abstract:DIFFICULTIES IN PROGRAMMING AUTONOMOUS ROBOTS CONTINUE TO IMPEDE WIDESPREAD APPLICATIO OF AUTOMATION. HIGH LEVEL PROGRAMMING CAPABILITY THAT PERMITS THE USER TO THINK IN TERMS OF THE COMPLETE TASK AS OPPOSED TO THE INDIVIDUAL MOVEMENTS REQUIRED OF THE ROBOT DOES NOT YET EXIST. IN RESPONSE TO THIS… more
Abstract:MERCURY IS A HIGHLY TOXIC MATERIAL THAT OCCURS IN BOTH ORGANIC AND INORGANIC FORMS. BECAUSE OF ITS WIDESPREAD INDUSTRIAL USE THE WHOLE POPULATION IS EXPOSED TO MERCURY COMPOUNDS EVERYDAY. THERE IS A NEED FOR A FAST, EASY TO USE, INEXPENSIVE, SENSITIVE METHOD FOR THE DETECTION OF MERCURY TO REDUCE… more
Abstract:A TECHNIQUE FOR OBTAINING TRUSTWORTHY COMPILATION BASED ON A COMPILATION CHECKER (SIMILAR TO A PROOF CHECKER) IS PROPOSED. THE TRANSFORMATIONS USED IN A COMPILER WILL BE FORMALLY SPECIFIED AND VERIFIED USING INTERPRETER EQUIVALENCE METHODS. THE COMPILER WILL BE INSTRUMENTED TO PRODUCE A TRACE OF THE… more
Abstract:THE PHYSIOLOGICAL-THERMODYNAMIC BASIS FOR HYBRID VIGOR (YIELD HETEROSIS) IN CORN AND OTHER CROPS IS NOT PRESENTLY KNOWN. THUS, DEVELOPMENT AND SELECTION OF INBRED LINES FOR HYBRID VIGOR RELIES ON GENERAL KNOWLEDGE ABOUT HETEROTIC GROUPS, NUMEROUS CROSSES, AND EXTENSIVE FIELD TESTS TO ACHIEVE 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.
