Abstract:A reflectiver near infrared (NIR spectrometer is proposed for the noninvasive measurement of surface and deep tissue pH. Previous experimental studies have demonstrated on a preliminary basis the ability to estimate liquide pH in complex biological matrices based on NIR spectra [Dre 90][Sch 93],… more
Abstract:Control of recirculated water in aquaculture systems will require the monitoring of several important parameters to assure the absence of toxic conditions and verify the effectiveness of treatment processes. These parameters include nitrite, ammonia, pH, dissolved oxygen and total suspended solids.… more
Abstract:The long-term objective of CCT is to develop and commercialize new transesophageal (TE) pacing systAvailable systems pace only the atria, but one, the other, or both heart chambers must be paced to sneeds in medical emergencies and Advanced Life Support protocols. This application describes… more
Abstract:We will establish the feasibility of integrating state-of-the-art multimedia (interactive video andanimation) into existing award-winning software - BARN (Body Awareness Resource Network). BARN was dthe University of Wisconsin (1981-88) to provide health promotion information directly to… more
Abstract:The work proposed will develop a Noise-Canceling Fiber Optic Microphone (NCFOM) with a digital output signal for use with AF communication systems. A first-order vented cavity NCFOM design and a dual diaphragm NCFOM design will be analyzed using already developed equivalent frequency circuits to… more
Abstract:Stochastic resonance is an effect in which a nonlinear system amplifies a weak and noisy modulated signal. Some signals that are too weak for direct detection can be measured using stochastic resonance systems. This project Will examine the feasibility of developing an optical stochastic resonance… more
Abstract:ORBITEC proposes to design and develop a small commercial thruster which combines innovative concepts to produce a scalable, high response, precisely controlled, low cost, highly reliable family of thrusters for altitude control, orbit change, and maneuvering applications in space. The key concepts… more
Abstract:An innovative Earth-based aerodynamic levitator with closed-loop stability control to enhance high temperature materials processing techniques is proposed. In current approaches, turbulence-induced instability imposes limits in levitator effectiveness and limits the sample dimension capacity. With… more
Abstract:The Shared Multi-use Remote Robotics Facility (SMURRF) will provide a simple, Flexible, and functional manipulator to assist space operations in an unmanned mode. Shared Multi-use Robotics Facility: Shared - Combined Automated and human controlled modes of operation; Multi-use - the wide range of… more
Abstract:This proposed effort will develop the Voice Activated Poor Visibility Emergency Response Systems (VAPERS) by combining hardware and software concepts in a manner that will significantly increase Crash-Fire-Rescue (CFR) vehicle effectiveness without a corresponding increase in operator workload. The… more
Abstract:ORBITEC proposes a Miniature in-Situ Smart Fatigue Monitor (MISSFM) that will accurately assess and monitor fatigue damage in eal time of almost any structural component. Phase I will design and demonstrate technology to achieve a solid state device to measure and display component strain and… more
Abstract:ORBITEC proposes to develop haptic interface software for virtual reality simulations and assisted telerobotic manipulation. A haptic interface is a device which allows a human 'observer' to explore and interact with a virtual environment or control a remote manipulator using the sense of touch. … more
Abstract:With the increased understanding of the role of specific cytochrome P450 isoforms in drug metabolisgrowing need for improved in vitro methodology using purified P450s. The major drawbacks to currentinterference from contaminating enzymes present in heterogenous assay systemss and difficulties in… more
Abstract:Though radioactivity is widely used in bioassays due to its high sensitivity and convenience, safety and environmental concerns have accelerated efforts to eliminate its use. Recent procedures using luminescence have often surpassed conventional isotopic methods; among these the luminescence 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.
