Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA scientific and technical information (STI) program plays a key part in helping NASA maintain this important role. The NASA STI program operates under the auspices of the Agency Chief Information Officer. It collects, organizes, provides for archiving, and disseminates NASA's STI. The NASA S...

At present, few laser sources are available in the vacuum ultraviolet (VUV) region and most of them are either complicated or expensive. Among these are excimer lasers based on rare gas dimers [1]. However, limited tunability and the use of e-beam excitation impose serious experimental restrictions. Tunable radiation can be generated from nonlinear methods using frequency mixing in gases [2,3],...

Analytical results have been presented for an optically illuminated InGaAs MESFET with opaque gate. The excess carriers due to photo generation are obtained by solving the continuity equation. The energy levels are modified due to generation of carriers. The results of I–V characteristics under dark condition and under illumination have been compared and contrasted with the GaAs MESFET.

In this study, X-ray fractography’)-‘) technique was applied to the (GZ+~) dual phase stainless steel. Effect of the rolling direction on fatigue properties was discussed. Residual stress near the surface was measured by using X-ray diffraction method to the depth direction. Relations between X-ray parameter and fracture mechanics parameter were examined. As the result, distribution of the phas...

We present a decentralized self-X architecture for distributed neighborhood based search problems using an overlay network based on random graphs. This approach provides a scalable and robust architecture with low requirements for bandwidth and computational power as well as an adequate neighborhood topology, e.g. for several instances of parallel local search and distributed learning. Together...
