Abstract:We developed a voice activated computer system for individuals with mental retardation andsevere disabilities. Named the Sound-to-Speech Translation with Graphics System (STS/Graphics), thissystem presented photographic quality symbols for choice making on the computer monitor to the userand… more
Abstract:THE PROJECT IS DEVELOPING A MICROPROCESSOR WHICH WILL BECOME THE BRAIN FOR INTELLIGENT BUILDINGS (BIB). THE BRAIN DISCERNS THE STATE OF THE BUILDING BY EVALUATING SIGNALS FROM THE SENSOR NETWORK AND ISSUES APPROPRIATE COMMANDS TO ACTIVE AND PASSIVE CONTROLLERS TO MODERATE THE EFFECTS OF SEISMIC… more
Abstract:Current sensors employed for operation of the V-22 in the TF/TA mode include a microwave radar and a FLIR night vision system. A new forward looking sensor is needed to allow higher speeds at lower altitudes, in more adverse weather, while being covert for the TF/TA operating mode. Although this… more
Abstract:Recent research in several laboratories has indicated that ibogaine may be of value in thetreatment of addictions to a number of drugs of abuse. Ibogaine, itself, is a hallucinogen. Thus,widespread use of ibogaine pharmacologically will inevitably lead to abuse of this substance. Currently,there is… more
Abstract:A new approach to generating atomic hydrogen (and possibly N and O) will give atomic fluxes of 10(-19) atoms/cm(-2) over a three inch wafer positioned three inches in front of the source. Scalt up to larger areas may be possible in phase II. We will examine the use of this source as an alternative… more
Abstract:Ionwerks has begun an internally funded project to design and manufacture an MBE growth chamber specifically designed and optimized for wide bandgap nitrides (compatible with Si/Ge growth also). This chamber will include two proprietary growth techniques which we have found to be crucial for… more
Abstract:UNDERSTANDING THE BEHAVIOR ON N- AND P-TYPE DOPED CUBIC BORON NITRIDE (CBN) THIN FILMS IS IMPORTANT TO THE ABILITY TO MAKE ELECTRONIC DEVICES TO TAKE ADVANTAGE OF THE THERMAL AS WELL AS ELECTRONIC PROPERTIES OF CBN. N- AND P-TYPE DOPED CBN ARE BEING GROWN USING ATOMIC LAYER EPITAXY (ALE) IN A… more
Abstract:JChaffee & Associates proposes the development of advanced methods for using GPS with the goal of automating space operations. This includes navigation, attitude determination, and relative positioning from launch through orbital operations and de-orbit. To accompolish this task, a new generation of… more
Abstract:THIS PROJECT IS AIMED AT THE DEVELOPMENT OF A NEW GENERATION OF ROTARY BLOWOUT PREVENTERS CAPABLE OF SAFE, RELIABLE, AND COST EFFECTIVE HANDLING OF THE HIGH PRESSURES EXPECTED IN UNDERBALANCED HORIZONTAL AND DIRECTIONAL DRILLING APPLICATIONS. PRESSURES OF UP TO 5,000 PSI (OR EVEN HIGHER) CAN BE… more
Abstract:This proposal is aimed at the development of a gas pressure relief valve with modulating pressure control that provides for low- or no-impact during venting of low temperature cryogens in the range of pressures from 20 to 44 MPa. The development will concentrate on designs which provide inherent… more
Abstract:A NONDESTRUCTIVE ULTRASONIC METHOD CAPABLE OF QUANTITATIVELY EVALUATING THE BOND STRENGTH AND RESIDUAL INTERFACE STRESSES AT BRAZED JOINTS, SUCH AS CARBON/CARBON-COPPER USED IN FUSION REACTOR FIRST WALL STRUCTURES, IS PLANNED. THE MECHANICAL PROPERTIES AT THE INTERFACE CONTROL THE INTIMACY OF… more
Abstract:MOST ELECTROPOLISHING TREATMENTS FOR STAINLESS STEELS EMPLOY MULTIPLE OPEN MILDLY ACIDIC VESSELS. CONCERNS REGARDING FUMES AND CARRYOVER OF MORE AGGRESSIVE ACIDS MAKE COMMERCIAL TREATMENT FOR TITANIUM UNAVAILABLE. AN AUTOMATED ENCLOSED SINGLE TANK ELECTROPOLISHING MACHINE PROVIDES AN… more
Abstract:The object-oriented (OO) paradigm has demonstrated that it can produce software systems that are more reliable, have greater re-use capabilities, and are easier to understand, maintain, and modify. As the technology matures, the desire to convert large-scale, non-OO systems into OO systems increases… more
Abstract:A LOW VISION READING OR BIOPTIC TELESCOPE CAN BE DRAMATICALLY AN ORDER OF MAGNITUDE LESS IN COST THAN PRESENT MOUNTED TELESCOPES BY BEING CAST INTEGRAL WITH THE CARRIER SPECTACLE LENS. PREVIOUS SOLID TELESCOPE DESIGNS HAVE NOT USED ASPHERIC CURVES TO REDUCE ABERRATIONS NOR PLASTIC CASTING TECHNOLOGY… more
Abstract:SOFTWARE PERFORMANCE ENGINEERING (SPE) TECHNIQUES HAVE THE POTENTIAL TO REDUCE COST AND IMPROVE RELIABILITY OF SYSTEMS. THE TECHNIQUES ALLOW QUANTITATIVE ASSESSMENT OF THE PERFORMANCE CHARACTERISTICS OF EMERGING SOFTWARE SYSTEMS. THIS PERMITS THE SELECTION OF REQUIREMENTS AND DESIGN ALTERNATIVES… more
Abstract:Status epilepticus and seizures are life-threatening emergencies, especially in children. Whileintravenous (IV) drugs can rapidly halt seizures, gaining IV access in a struggling patient can be difficultto impossible. An established alternative to IV in pediatrics is intraosseous (IO) infusion into… more
Abstract:This grant will study the feasibility of developing convenient, cost-effective methods of synthesisfor L-sugar nucleoside and nucleotide analogue chemotherapeutic agents and to investigate theirphosphorylation and uptake by malignant cells in tissue culture. L-sugar-based therapeutic agents… more
Abstract:THE THREE-WAY CATALYTIC CONVERTER IS THE MOST IMPORTANT DEVICE MAKING TODAY'S AUTOMOBILES COMPLY WITH EXISTING EMISSION LAWS. THE FIRST TWO OR THREE MILES IN A TYPICAL 22-MINUTE, 12-MILE COMUTE IN TODAY'S VEHICLES RESULT IN THE EMISSION OF HALF OF THE TOTAL NON-METHANE HYDROCARBONS, WHICH RESULT IN… more
Abstract:Critical systems need protection from power failure in the field environment. The current generation of uninteruptible power supplies (UPS) is based on storage batteries. This severely limits power density and causes the size of the unit to rise rapidly as the discharge time required increases,… 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.
