Abstract:Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transitted or received, ie.e, one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency, nulls begin to… more
Abstract:Satellite Communication (SATCOM) is a necessity for teams (military or commercial) that are deployed away from their parent organizations. Unfortunately they may not have sufficient power supply/battery capability. By combining a SATCOM Antenna and Solar Cell Array protable, lightweight, and… more
Abstract:The primary objective of this research is to develop a novel optical multiplexing/demultiplexing device to combine many separate laser channels for communications applications. For both free space and fiber optic laser communications it is desirable to have a multiplexing scheme which has many… more
Abstract:The goal of this project is to create tools to support the formal verification of VHDL designs. Two existing formal verification tools will be enhanced to support VHDL. The first, Spectool, will allow a class of designs, the synchronous finite-state controlled systems, to be specified and verified… more
Abstract:EXISTING COMMERCIAL MODELING AND SIMULATION SOFTWARE PACKAGES DO NOT ADEQUATELY PREDICT THE BEHAVIOR OF COMPLEX COMPUTER-CONTROLLED SYSTEMS BEING DEVELOPED AND FIELDED TODAY. THESE "HYBRID" SYSTEMS INVOLVE DISCONTINUOUS PHENOMENA SUCH AS MECHANICAL PARTS ENGAGING AND DISENGAGING (E.G., SPACECRAFT… more
Abstract:It is difficult to exchange and use information between different office automation software tools. The user must spend excessive time learning and linking tools rather than doing the primary job. The proposed open framework expert system approach makes the technology of the tools transparent to the… more
Abstract:THE CELLULAR TELEPHONE INDUSTRY HAS GREATLY EXPANDED ITS USER COMMUNITY SINCE ITS INTRODUCTION IN THE UNITED STATES ONLY TEN YEARS AGO, AND IT CONTINUES TO DEVELOP RAPIDLY. IT IS AXIOMATIC THAT SYSTEM COSTS, RELIABILITY, AND PERFORMANCE CAN BE IMPROVED THROUGH THE USE OF HIGH BANDWIDTH, HIGHLY… more
Abstract:RESIDUAL LIFETIME EVALUATION OF EXISTING NUCLEAR FACILITIES REQUIRES DETAILED INFORMATION REGARDING CONDITION OF CONTAINMENT AND SUPPORT STRUCTURES. CURRENT NONDESTRUCTIVE METHODS FOR SUBSURFACE EVALUATION OF REINFORCED CONCRETE USE COMPLEX EQUIPMENT AND RELY HEAVILY ON INTERPRETATION BY THE… more
Abstract:THIS PROPOSAL DESCRIBES A NOVEL APPROACH TO IMPROVING PERFORMANCE OF MTI RADARS FOR THE DETECTION AND CLASSIFICATION OF MODERN, LOW OBSERVABLE TARGETS IN RELATIVELY HIGH CLUTTER ENVIRONMENTS. AN IMPORTANT PART OF THIS APPROACH IS ATLANTIC AEROSPACE ELECTRONICS CORP'S. APPLICATION OF MORPHOLOGICAL… more
Abstract:CRYOPRESERVATION OFFERS THE OPPORTUNITY TO STORE EMBRYOS AND LARVAE OF THE HARD CLAM, MERCENARIA MERCENARIA, FOR EXTENDED PERIODS WITH NEGLIGIBLE LOSSES. OBJECTIVES FOR PHASE I RESEARCH INCLUDE (1) TO DETERMINE THE EFFICACY OF SELECTED CRYOPROTECTANTS IN PRESERVING AND STORING 2-8 CELL EMBRYOS, (2)… more
Abstract:THE GOAL OF THIS RESEARCH IS TO PRODUCE ACAP, A PERSONAL COMPUTER-BASED ADVISOR FOR FAMILIES AND CAREGIVERS OF ALZHEIMER'S AND OTHER DEMENTED PATIENTS. UTILIZING EXPERT SYSTEM TECHNIQUES,THE SYSTEM IS INTENDED TO PROMOTE AN UNDERSTANDING OF DEMENTIA RELATED DISEASE PROCESSES, PROVIDE AN OVERVIEW OF… more
Abstract:This project will use sequencing by hybridization (SBH) to develop a faster, more economicalmethod for sequencing and mapping. Current DNA sequencing procedures almost universally require gelelectrophoresis of DNA fragments and are cumbersome and slow. SBH promises to produce rapidly largeamounts of… 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.
