Abstract:Bone marrow transplant (BMT) is an extraordinarily rapidly growing field, and the number of transplants in the U. S. is expected to grow from a current rate of 15,000 per year to over 100,000 per year by 1995. This rapid expansion is due to the diversity in the types of bone marrow transplantation… more
Abstract:In vitro expansion of hematopoietic cells finds many applications in the clinic. This technique hasexpanding CD34+ cells for transplantation/re infusion, although most of the technology has consistedcultures in which there is variable CFUGM expansions and failure to maintain LTC IC (long term… more
Abstract:A HYBRID POWER PLANT, CONSISTING OF A DIESEL GENERATOR, A BATTERY FOR ENERGY STORAGE, A PHOTO-VOLTAIC ARRAY OR OTHER RENEWABLE ENERGY SOURCE, AND AN INVERTER/BATTERY CHARGER, WILL BE ECONOMICALLY FEASIBLE IN THE NEAR FUTURE BOTH WITHIN THE UNITED STATES AND THROUGHOUT THE DEVELOPING WORLD WHERE… more
Abstract:As the ability to communicate with the health care system becomes more important, there isa risk that minority populations, particularly non-English speaking and undeserved persons, will fallfurther behind in the level of care they receive. We are currently developing a general healthcare planfor… more
Abstract:The use of dedicated pulsatile ventricular support devices (VAD) for circulatory support is becoming an accepted treatment modality for adult patients requiring support due to post-cardiotomy pump failure or post-AMI cariogenic shock; the VAD could also be used as a bridge to transplant. Although… more
Abstract:The limited availability of donor hearts for people with end stage heart failure has driven the condevelopment of mechanical circulatory support systems (MCSSs). MCSSs can be broadly classified intocontinuous flow systems. Pulsatile systems drive blood indirectly through blood pumps, resulting… more
Abstract:Minimal access abdominal surgery through the laparoscope has generally replaced surgical procedureslaparotomy for several common procedures, including cholecystectomy and appendectomy. More complicatgastrointestinal operations are also being attempted laparoscopically. Many of these procedures… more
Abstract:Calcification of blood contacting surfaces has been the key impediment to the development of polymevalve prostheses and other polymeric implantables. The deposition of calcium plaques as hydroxyapatiand potentially leads to valve dysfunction. That calcification proceeds preferentially along… more
Abstract:Standard Digital CMOS silicon circuits will have high quality Thin Film emitters, and modulators integrated on to the silicon using epitaxial liftoff and results in low cost opto-electronics in the near future. ABJ Integration is a leader in the field and proposes to design an optimized FPA readout… more
Abstract:DSL (Dipole Source Localization) is an important advance in evoked potential research because it prinformation on the location of equivalent dipole generators within the brain, and also separates thesimultaneously-active generators. Since evoked responses are used in both research and in the… more
Abstract:This research relates to evoked response testing of humans. The goal is to develop and test a methorecording the middle-latency auditory evoked-potential, to click or tone-pip stimuli at stimulus rep60 Hz, including 40 Hz. This may provide a test of cortical function which is especially sensitive… more
Abstract:Our goal is to develop external head shape/skull parameter measurement techniques which will permitconstruction of Boundary Element Method (BEM) head shape models to improve Dipole Source Localizatioprocedures, useful in analyzing brain Event-Related Potentials (ERPs) and magnetoencephalograms… more
Abstract:The objective of this effort is to demonstrate a superior prototype diagnostic system and controller for electrical power systems based on AbTech's abductive polynomial network technology. This technology enables designers to semi-automatically model the complex and dynamic behavior of very… more
Abstract:Intelligent processing of battlefield sensor data information provides substantial force-multiplying benefits. The timely and cost-effective leveraging of information provides a significant advantage over adversaries who do not possess comparable information processing capabilities. Among these… more
Abstract:AbTech will survey the hardware and software available to determine what capabilities should be included in a natural language understanding mission planning assistant. A language parsing and encoding system in ANN will be used to parse and encode ASCII outpuf resulting from a voice recognition… more
Abstract:THIS PROJECT DEVELOPS AND FIELDTESTS A COMMERCIAL PROTOTYPE SOFTWARE PACKAGE DESIGNED TO PROVIDE USERS OF SINGLE-SWITCH INPUT DEVICES CONTROL ACCESS TO EDUCATIONAL SOFTWARE, MULTIMEDIA PROGRAMS, AND RECREATIONAL ACTIVITIES FOR IBM AND PC-COMPATIBLE COMPUTERS. THIS POPULATION INCLUDES INDIVIDUALS… more
Abstract:The objective of this project is to extend the existing Message Translator and Validator (MTV) model's range of applicability for a variety of application areas and platforms. The MTV model is a scalable set of Ada code templates and generics that convert between external communication formats and… 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.
