Inflatable or self-deployable systems offer the only practical way to achieve space deployed antennas with low mass at large aperture. In this Phase I program, open-celled rigid polyurethane foams were developed for use in self-deploying antenna structures. Advantages of such a system relative to current systems include high volumetric efficiency of packing, inherent restoring force, low (or no) o ...

70307 Many DOE sites have the need to monitor radionuclide contamination in surface water, groundwater, soils, and the vadose zone. In many cases, a real-time and/or remote monitoring capability is desired. Existing site characterization procedures typically involve the collection and shipment of samples to an off-site laboratory, which leads to costly delays in site remediation as ...

DESCRIPTION (provided by applicant) This project will develop an artificial intelligence to provide the core functionality for virtual reality and computer based treatments for anxiety disorders. The use of artificial intelligence offers a number of advantages over existing treatments: (1) artificial intelligence provides personalized treatment - using multiple real time physiologic and subjective ...

"Magnetic field-enhanced electrocatalysis at the hydrogen and air electrodes of PEM fuel cells have reported improved power densities, three-fold over conventional PEMFCs. Leddy, et al. used micron-sized polymer-encapsulated beads of permanent magnetsplaced in conventional inks of carbon-supported platinum electrocatalysts to enhance MEA performance. Their work showed a qualitatively improved CO ...

"To be commercially competitive, PEM fuel cells have to be able to run on readily available fuels. Fuel reformers are practical, but fuel cell anode catalysts are severely poisoned by small quantities of carbon monoxide from the reformer. Despite mucheffort invested into increasing CO tolerance, desired performance levels have not been achieved.Recent data has shown great promise in mitigating t ...

70558 The control and dynamic operation of Fuel Cell/Turbine Hybrid power plants will require a synergy of operation between subsystems, increased reliability of operation, and reduction in maintenance and downtime. Futhermore, the control strategy of the power plant will play a significant role in system stability and in ensuring the protection of equipment to promote maximum life. T ...

"Several ocean animals, including sea turtles, migratory fishes, and lobsters, have evolved accurate compasses for undersea navigation. Some have even evolved a way to move directly to specific geographic locations by exploiting distinctive features of theEarth's magnetic field. MTI, Ltd. in conjunction with the University of North Carolina's Lohmann Laboratory, will develop techniques to adapt t ...

Clocks and pulse sources are critical elements for next generation IC¿¿s such as DSP¿¿s and ¿Yprocessors which depend critically on stability and jitter. Clock skew becomes significant because of the large chip dimension. ADC¿¿s and DAC¿¿s are mixedsignal circuits which demand extremely precise clocks at multi GB/s rates. Telecommunication transceivers and transponders ...

True time delay (TTD) is essential for optically coupled phased array radars. How to implement the phased array is not so clear since a complete manifold of delays for transmit and delays must be implemented without introducing glitches associated withswitching. In a continuous transmit and receive mode, it is difficult to interrupt the operation to implement a new TTD delay combination in a noi ...
