Abstract:Hematopoiesis, the regulated production of mature blood cells, is a complex scheme of multilineage differentiation which occurs mainly in the bone marrow of adult mammals. Mature cells are continuously produced from progenitor (or precursor) cells. Consequently, assays which detect these progenitor… more

Abstract:BETWEEN COCHLEAR IMPLANTS AND QUADRI/PARAPLEGICS, THERE ARE APPROXIMATELY 700,000 PERSONS IN THE U. S. WHO WOULD BENEFIT FROM PROSTHETICS UTILIZING NEURAL OR NEUROMUSCULAR STIMULATION. SUCH SYSTEMS REQUIRE IMPLANTABLE, HIGH-SPEED, BI-DIRECTIONAL, TRANSCUTANEOUS DATA TRANSMISSION IMMUNE TO VARIATIONS… more
Abstract:Endoscopic exploration of the utero-fallopian region is useful and may become a more general observational modality if a viewing instrument can be build with a front end that is disposable and inexpensive, has a small diameter with potential for transcervical introduction without anesthesia, and can… more
Abstract:High speed, low cost optical self routing optical crossbar switches with gigabit data rates are key components in optical communication and routing systems. We propose to fabricate and study a monolithically integrated optical crossbar switch which will be inexpensive and high performance. This… more
Abstract:Preliminary studies have demonstrated the feasibility of a novel computational scheme which will address critical errors in the present methodology of source localization. These studies will also make it feasible to obtain source location and pattern of activity based on realistic models of the head… more
Abstract:The objective of this effort is to demonstrate a prototype advanced diagnostic system for the T800 turboshaft engine using a hybrid polynomial network and production-rule expert system. The resulting system will demonstrate the feasibility of developing a revolutionary diagnostic capability which… more
Abstract:THIS PROJECT DEVELOPS AND FIELD TESTS A PROTOTYPE SOFTWARE/HARDWARE ASSESSMENT PACKAGE TO SUPPORT ASSISTIVE TECHNOLOGY ASSESSMENT PERSONNEL RESPONSIBLE FOR SELECTION OF APPROPRIATE CONTROL INTERFACE DEVICES FOR PERSONS WHO HAVE DIFFICULTY INTERACTING WITH THEIR ENVIRONMENT. THIS POPULATION INCLUDES… more
Abstract:Sports Center Unlimited will be a simulated sports/leisure activity exploration program for youths with physical disabilities. The Phase I prototype will run on a Macintosh using QuickTime multi-media with sound, color, video, animation, and user interaction. As one of many animated characters, each… more
Abstract:A NEW TECHNIQUE IS PROPOSED FOR THE PREPARATION OF METAL-SUPPORTED METAL (MSM) CATALYSTS. THE KEY FEATURE OF THIS TECHNIQUE INVOLVES THE PREPARATION OF A THIN LAYER OF POROUS METAL ON TOP OF A METAL SUBSTRATE SUCH THAT THE POROUS METAL SURFACE IS AN INTEGRAL PART OF THE METAL SUPPORT. SUBSEQUENT… more
Abstract:THE PURPOSE OF PHASE I OF THIS RESEARCH PROJECT IS TO CRITICALLY REVIEW THE EXISTING COMPUTERIZED EOP SYSTEMS FOR BOTH PWR AND BWR PLANTS, DEVELOPED BY VARIOUS NATIONAL AND INTERNATIONAL ORGANIZATIONS TO FULLY UNDERSTAND THEIR ADVANTAGES, DISADVANTAGES AND LIMITATIONS IN TERMS OF THEIR IMPACT ON… more
Abstract:COMPUTERIZED DATA COLLECTION DEVICES EXIST AND ARE BEING USED IN VARIOUS APPLICATIONS AT SOME NPPS FOR SYSTEMS AND EQUIPMENT NOT INSTRUMENTED IN THE CONTROL ROOM. HOWEVER, CURRENT APPLICATIONS IN THE NUCLEAR POWER INDUSTRY ARE RATHER SPORADIC AND NOT EXPLOITING THE FULL POTENTIAL OF THE TECHNOLOGY.… more
Abstract:THIS PROJECT INVESTIGATES A NEW TYPE OF HIGH Q RESONANT STRUCTURE, WHICH HAS RECENTLY BEEN DEMONSTRATED, TO DEVELOP HIGH GRADIENT, SUPERCONDUCTING ACCELERATOR CAVITIES. BASED ON THE CONCEPT OF A PHOTONIC BAND GAP (PBG) RESONATOR, THESE NEW STRUCTURES ARE PHYSICALLY SIGNIFICANTLY DIFFERENT FROM THE… more
Abstract:THE EFFECTIVENESS OF THE NEUTRAL PARTICLE BEAM (NPB) MISSILE DEFENSE SYSTEM DEPENDS ON THE SUCCESSFUL ACCELERATION OF HIGH BRIGHTNESS H ION BEAMS AT HIGH CURRENTS WITH CONTINOUS WAVE (CW) OPERATION. PRESENT BASELINE DESIGNS FOR THESE POWERFUL LINAC SYSTEMS INCLUDE ONE OR MORE STAGES OF BEAM… more
Abstract:The primary goal of this Phase I design study is to develop the design of an accelerator-based neutron source for clinical boron neutron capture therapy (BNCT) using the compact radio-frequency quadruple (RFQ) linear accelerator. This accelerator design study will be completed in collaboration with… more
Abstract:THE USE OF THE RADIO FREQUENCY SUPERCONDUCTING ION LINACS HAS GROWN STEADILY OVER THE PAST 15 YEARS, PRIMARILY FOR APPLICATIONS IN NUCLEAR AND ATOMIC PHYSICS WHERE FLEXIBILITY N ION SPECIES AND ENERGY ARE REQUIRED. THIS TECHNOLOGY CONTINUES TO BE ACTIVELY DEVELOPED AT SEVERAL LABORATORIES WORLDWIDE.… more
Abstract:WE PROPOSE THE DEVELOPMENT OF AN INNOVATIVE NEUROCONTROLLER THAT GENERATES TRAJECTORIES WHICH REDUCE PLASMA EFFECTS ON THE COMMUNICATION SYSTEM OF THE NASP. WE WILL MODEL PLASMA SHEATH GENERATION AND INCORPORATE THIS MODEL INTO A GHAME FLIGHT SIMULATOR ON A SILICON GRAPHICS WORKSTATION. THIS MODEL… more
Abstract:THIS PROPOSAL INVOLVES RESEARCH INTO A SUPERCOMPUTER-BASED ENVIRONMENT FOR RESEARCH INTO MASSIVELY PARALLEL NEURAL-NETWORK ALGORITHMS FOR LARGE SCALE, COMPUTATIONALLY INTENSE PROBLEMS. THIS ENVIRONMENT WILL HAVE APPLICATION TO AREAS SUCH AS IMAGE PROCESSING, PATTERN RECOGNITION, CONTROL SIGNAL… 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.
