Abstract:High Performance Computing technology has advanced significantly, and advanced parallel computers are being built, with DOE leadership. Yet, the American engineering and manufacturing industry has not started leveraging parallel computing at a significant level, partly because of the challenging… more
Abstract:Currently, cast-iron is nearly exclusively used for car brake rotors. Replacing cast-iron by a high- temperature, creep-resistant aluminum alloy could translate into about 80 lbs (36 kg) in weight reduction for a typical car, thus improving its gasoline mileage and reducing its greenhouse gas… more

Abstract:Two-electron reduced-density-matrix (2-RDM) methods represent all of the electrons in any molecule or material with only two electrons by replacing the wave function by the 2-RDM as the basic variable for quantum many-electron theory. The 2-RDM methods, developed by David Mazziotti at The University… more
Abstract:The objective of this project is to develop and energy efficient method to convert CO2 and water to formic acid. Formic acid is widely used in Europe as an alternative to antibiotics in animal feed, and for grain preservation, but it has not been adapted in the US because it is more expensive than… more
Abstract:Computational simulation of many of todays important and challenging problems in science and engineering involve multiple, complex, interacting physical systems, and often involve combustion or other sources of energy release. This multiphysics modeling refers to the advanced coupled modeling… more
Abstract:To enable advanced power plant technologies (e.g. Integrated Gasification Combined Cycle) and improve the thermal efficiency of the power plant, it is desired to raising the inlet temperature of gas turbines which demands blade and vane materials exhibiting superior high temperature properties,… more
Abstract:Modern flight-critical systems include hundreds of thousands to millions of lines of code. The Boeing 777, for instance, includes over 2 million lines of code. Future projects will only feature an increasing amount of source code, mostly written in the C programming language. The only way to… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project aims to develop inexpensive carbon dioxide sensors for heating, ventilation and air conditioning (HVAC) controls. CO2 sensors are now being used to lower heating bills and improve air quality in new commercial buildings, but they have… more
Abstract:The project team is developing a prototype of InfoWriter, a Web 2.0 concept mapping tool and writing environment to support students in writing informational and explanatory texts. The product will be used in middle and high school English Language Arts classrooms, and others as appropriate, to… more
Abstract:ABSTRACT: Mycotoxins are toxic secondary metabolites of molds and fungi, many of which are pathogenic to humans. In general, mycotoxins enter the body through the skin, digestive tract, or through respiration. Exposure to a few milligrams can be lethal. Mycotoxins have a high likelihood of … more
Abstract:This Fast Track SBIR project aims at developing electrically insulated scanning probes suitable for high resolution electrical nano-imaging in conductive solutions. These probes, when used in atomic force microscopy, enable scanning electrochemical microscopy (AFM-SECM) to be performed. This method… more
Abstract:This Small Business Innovation Research (SBIR) project will employ Nanofiltration to generate sulfate ion feedstocks and high current density on-site generation (synthesis) of the powerful oxidant peroxodisulphate (“persulfate”) with novel, high reliability boron-doped untrananocrystal-line… more
Abstract:DESCRIPTION (provided by applicant): There is an acute need for the development of a new class of selective and sensitive portable analytical sensors to enable reliable monitoring of multiple classes of chemical analytes in complex biomatrices. Current preferred methods for determining the… more
Abstract:DESCRIPTION (provided by applicant): Artificial cardiovascular devices (ACDs) including ventricular assist devices (VADs) and mechanical heart valves (MHVs) have been implanted into millions of patients, to save or improve their lives. The increasing success of ACD implants has been accompanied… more
Abstract:Advanced missile radomes require robust high temperature materials for high speed flight. Current advanced radome materials are limited by thermal, electrical, and impact performance. ATFI has developed an oxide ceramic matrix composite (CMC) which has demonstrated required electrical, thermal and… more
Abstract:We will develop an efficient Graphics Processing Unit (GPU) based parallel Binary Decision Diagram (BDD) software package, and will also combine it with our GPU-based parallel SAT solver that we are currently developing in a NASA SBIR Phase II project in order to solve much larger and more complex… more
Abstract:In the proposed project, we will formally verify the correctness of the interaction between a Real-Time Operating System (RTOS) and user processes under various operating scenarios, such as multitasking, interrupt handling, user and kernel mode switching. The formal verification will be done… more
Abstract:Radar signatures of small boats and ships are inherently complex due to their myriad topside features: railings, antennas, masts, ladders, armaments, pilot stations, outboard engines, storage bins, etc. In boats, the use of fiberglass and other radar-penetrable materials for hulls and decks further… more
Abstract:Modern military systems contain numerous avionics and electronic systems that must perform to very high standards in hostile environments in the presence of numerous potential sources of electromagnetic interference (EMI). On airborne platforms for example, there could be dozens of RF systems… more
Abstract:Modern marine radar systems can provide detection and tracking of various sizes of ships, and progress in signal processing has allowed for the detection of some smaller and faster targets, largely due to the wake generated by the boats. However, detection of small boats still remains a very… more
Abstract:Our team proposes to expand the capabilities of an existing software tool so that is capable of producing CAD models and associated configuration information for representative antenna designs given the type of information that can be found on a vendor's specification sheet. The user will… more
Abstract:Modeling and simulation tools fill a critical role in system integration by allowing engineers to predict potential EMI problems and explore solutions prior to fielding of the platform. While providing a powerful and necessary capability, the use of these simulation tools is often hindered by the… more
Abstract:Quick detection of Chemical/Biological (CB) agents in the field can provide critical reconnaissance and contamination avoidance. CB agents pose a serious threat to both civilian and military sectors, and present techniques rely on dangerous collection methods, active measurement through external… 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.
