Abstract:Nuclear angiography is considered the superior technique for accurate quantitative measurementof ventricular function. Despite this, a growing and predominant fraction of such measurements areperformed via echo- cardiography. Two factors have strongly influenced this shift to a less than… more
Abstract:Positron emission tomography (PET) is recognized as a superior diagnostic imaging techniquein a number of important clinical areas. However, it is currently relegated to a research role due to itsdependence upon in-hospital cyclotrons for radioisotope production with resultant high cost… more
Abstract:Millimeter wave imagers are being investigated as solutions to a variety of military and commercial problems. Millimeter waves penetrate fogs and clouds thus allowing for operation under conditions of adverse visibility. In addition, millimeter waves penetrate clothing and reveal concealed weapons… more
Abstract:The primary objective of this Phase I research is to develop a tool for evaluating the dependability of fault-tolerant computing systems. Dependability has traditionally been evaluated through combinatorial and Markov modeling. These analytical techniques have several limitations which can… more
Abstract:WE PROPOSE AN INNOVATIVE APPROACH WHICH LEADS TO THICK TUNGSTEN WIRES FULLY EMBEDDED IN SOLID DIAMOND SLAB. IN THIS APPROACH, THIN FILMS OF CHEMICAL VAPOR DOPOSITION (CVD) DIAMOND ARE COATED WITH A REFRACTORY METAL AND THE METAL IS PATTERNED. THESE PATTERNED LAYERS FILMS ARE STACKED AND PROPERLY… more
Abstract:Cross contamination between patients, medical personnel and home care givers can be a serious problnursing care. Whenever the integrity of the skin barrier is broken by surgical procedures, irritatiocommon skin bacteria may cause infections. Infection may be reduced by washing the skin with a… more
Abstract:SYSTEMS & PROCESSES ENGINEERING CORPORATION (SPEC) IS PROPOSING TO DEVELOP A DEEP STRIKE SECURITY EXPERT PLANNER (DSSEP). DSSEP IS A HIGH PERFORMANCE EXPERT SYSTEM DECISION AID THAT ASSISTS COMMANDERS TO PLAN FOR THE SECURITY OF U.S. ARMY MANEUVER ELEMENTS, PROVIDING INCREASED ECONOMY OF FORCE AND… more
Abstract:System & Processes Engineering Corporation (SPEC) proposes to develop a high speed,high density solid state flight data recorder using state-of-the-art CMOS integrated circuit and Multi-Chip-Module (MCM) technologies. the solid state recorder will include 2 MEG x 8 synchronous dynamic random access… more
Abstract:Systems and Processes Engineering Corporation (SPEC) proposes to develop a chip set to digitize, compress, encrypt, encode, and modulate fast motion video and focal plane array waveforms. The ASIC chip-set will be integrated into a Multi-Chip Module (MCM) and will be compatible with existing… more
Abstract:Conventional fiber optic fluorosensors absorb and re-emit in the UV/VIS spectral range. The unavailability of UV/VIS light sources makes these fluorosensors prohibitively costly and unreliable. Systems & Processes Engineering Corporation (SPEC) proposes to develop an embedded fiber optic… more
Abstract:Systems & Processes Engineering Corp. (SPEC) proposes to develop a compact, low-cost multi-analyte immunomagnetic biosensor system for rapid, selective, and sensitive detection and identification of several individual viruses and toxins simultaneously in a biotoxoid mixture. The proposed biosensing… more
Abstract:The US Army is continually faced with the task of providing the crew members of weapon systems with realistic, high-quality training. This training must be based on known principles of instructional design, yet meet the needs of specific weapon system based training issues. The problem of providing… more
Abstract:The crew of direct fire weapon systems in an active fire fight are subject to information overload and conflicting priorities, particularly in a target-rich environment. Such parameters as distance to target, immediacy of threat, target value assessment (TVA), lethality against a specific target… more
Abstract:RESEARCHERS ARE EXPLORING NEW TECHNOLOGY THAT CAN BE USED TO DEVELOP A LOW-COST MODULAR NMR CONSOLE THAT CAN REPLACE ANY COMMERCIALLY AVAILABLE CONSOLE AND PROVIDE UP-TO-DATE PERFORMANCE AT A COST OF LESS THAN $100,000. RF TECHNOLOGY CURRENTLY USED IN CELLULAR PHONE AND OTHER CONSUMER PRODUCT… more
Abstract:This proposal discusses the need for a monitor on commercial aircraft capable of detecting RF emissions over a broad dynamic range and an extremely wide electromagnetic spectrum. The security monitor has two purposes: (1) detect inadvertent RF emissions from passenger's portable electronic devices… 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.
