Lithium Hydride is an attractive energy storage material. Its high heat of fusion (2582 kJ/kg) and its melting point (956 K) make it suitable for many applications. The best location for LiH storage capsules is inside a liquid metal heat pipe. The heat pipe facilitates heat transfer into and out of the capsules. The major drawback to using LiH is its high equilibrium hydrogen pressure. Since hydro ...

We are developing erbium doped fiber amplifiers (EDFAs) for optical communication systems, local area networks, fiber sensors and optical measuring instruments. The EDFA is a new and revolutionary technology that is having a profound effect on the design of lightwave system architectures and other applications. Never has a technology blossomed as fast as the EDFA: it went from a twinkle in the eye ...

Development of new solid lubricants is underway. Nanocrystalline lubricant particles embedded in hardcoating material will allow low friction and increased durability of mechanisms in sliding contact. Special attention is being given to materials used in prosthetics including hip implants, where release of wear debris is detrimental. Other uses for low friction nanocomposite coatings include high ...

THE COMBINATION OF A MAGNETOHYDRODYNAMIC (MHD) GENERATOR OF THE DISK TYPE WITH A (NERVA) REACTOR YEILDS AN ADVANCED SPACE POWER SYSTEM WITH GIGAWATT PULSE AND MEGAWATT CONTINUOUS OPERATING CAPABILITY, AT LOW SPECIFIC MASS AND HIGH SPECIFIC ENTHALPY EXTRACTION. THE NOVEL ASPECT OF THISSYSTEM IS THE DISK MHD GENERATOR OPERATING IN THE NON-EQUILIBRIUM MODE WITH CESIUM SEEDED HYDROGEN AS THE WORKING F ...

THE PRIMARY OBJECTIVE OF THIS PROPOSAL IS TO DESIGN AND BUILD A SYSTEM FOR FISHERY AND MARINE MAMMAL STOCK PREDICTION USING NONLINEAR SPATIO-TEMPORAL NEURAL NETWORK THEORY. WHILE THE CENTRAL ENGINE OF THE SYSTEM MAKES USE OFNONLINEAR NEURAL NETWORKS FOR PREDICTION, SEVERAL PERIPHERAL MODULES INCORPORATED IN THE DESIGN ASSIST THE USER IN EMPLOYING THE PREDICTOR FOR VARIOUS APPLICATIONS. IN PARTICUL ...

Incremental system/software integration and the maintenance and evolution of embedded systems are not well supported by current tools. This is particularly true of high-availability systems that can't be shut down to use off-line integration approaches. We have developed a software architecture that associates dynamic integration command statements with the code of the current and new components. ...

Frequency agile, intermediate power laser is being developed for diffractive beam steering and remote laser induced emission spectroscopy from spaceborne platforms. The system is an efficient compact, tunable, solid-state laser designed by combining the advent of high power laser diode arrays, with the unique characteristics of the new laser crystal, Cr:LiSAF. The laser which has a tuning range ex ...

Project will develop methods for the optimal management of sensor systems. As a specific application, we consider the nonlinear filtering of a vector diffusion process, with several noisy vector observations. Any number of sensors can be utilized in the signal processing performaned by the nonlinear filter. The problem considered is the optimal selection of a schedule of these sensors from the ava ...
