Service-oriented architectures (SOA) and, in particular, Web Services designs are widely adopted for the development of interoperable systems. In a dynamic scenario, a composed service may exploit component services in order to complete its task; composed services are variously distributed, and offered by different providers in different security domains and under different load conditions. So,...

Fabrication and characterization of U-shaped fiber optic pH probes utilizing evanescent field absorption spectroscopy and dye doped solgel immobilization technology are presented. The U-shaped probe is used to increase the evanescent field in the film and hence its interaction with the dyes present in the film. The influences of bending radius of the probe and the numerical aperture of the fibe...

OpenTuner can help users achieve better or more portable performance in their speci c domain through program autotuning. A key challenge for users seeking good autotuning performance in OpenTuner is selecting a search approach appropriate for problem. However, not only are current in-situ learning search approaches not robust enough to handle all search spaces, but there are also too many possi...

The process of empirical autotuning results in the generation of many code variants which are tested, found to be suboptimal, and discarded. By retaining annotated performance profiles of each variant tested over the course of many autotuning runs of the same code across different hardware environments and different input datasets, we can apply machine learning algorithms to generate classifier...

The structural and optical properties of polyvinyl alcohol (PVA) doped with different concentrations (0, 0.15, 0.5, 1, 2, 2.5, and 3 wt %) of ZnO nanoparticles were studied. ZnO nanoparticles were prepared by the solgel methode, and nanocomposite films were prepared using the solution casting methode. Nanocomposites films were characterized by X-ray diffraction (XRD), Fourier Transformer Infrar...

AbstractIn this study, the stress analysis of YBCO/CeO2/YSZ/CeO2/Ni architextured materials under cryogenic conditions was carried out for coated conductor applications. YBCO/CeO2/YSZ/CeO2 multilayer films were fabricated on Ni tape substrate using reel-to-reel sol-gel and Pulse Laser Deposition (PLD) systems. The microstructural evolution of high temperature superconducting YBCO film and buffe...
