The growth of technology is leading mankind to an increased awareness of the need for more intelligent systems. However, one of the bottlenecks in building intelligent systems is the difficulty of acquisition, testing and refinement of domain specialists' knowledge. Learning capability offers a way through this bottleneck. In this paper, we describe a(More)
In this study, we present a new approach toward titanium oxide nanowires. In this approach, the growth formation of the wires sets in at a temperature as low as 40 degrees C under ambient pressure. Moreover, we provide evidence that nanowires with distinctive TiO2-anatase and TiO2-B structures can be directly produced without further thermal treatment using(More)
BST nanoparticles were directly synthesized from solution at 70 degrees C and then wrapped with zinc doped MgO in solution. This core-shell structure was analyzed by a conjunction of XRD, HRTEM, and FE-SEM. The lattice cell parameter of BST core was found to have shrinkage. The lattice cell mismatch between core and shell creates a variation of lattice cell(More)
A small polished rectangular block of natural diamond unusually free from impurity zoning was examined by birefringence and synchrotron X-ray topography to map internal defects and assess effects of some accidental mechanical damage. ;Orthogonal-view' projection topographs facilitated comparisons between optical and X-ray images. Speedy and precise(More)
The authors extend their previous work (1990, 1991) on solving data acquisition and processing problems in power systems. The proposed methodology applies pattern analysis techniques to solve the network configuration, observability analysis and bad-data processing problems. Further associative memory models are investigated for the solution of the(More)
The cross-sectional RuO2/SiO2 composite films with different RuO2 and SiO2 and Ru2Si3 thin films, deposited by sputtering on silicon wafers and followed by the post-deposition annealing in the temperature range from 150 to 500 °C, will be investigated by transmission electron microscopy (TEM). The studies will provide important structural information on the(More)
The ZnO nanorods grown on in-situ synthesized ZnSe grains through the chemical vapour deposition method are reported here for the first time. With a suitable growth condition, single crystal ZnO nanorods grow on the well-defined bounded facets of the random shape ZnSe grains using Zn and Se powders without any metal catalyst. The growth direction of ZnSe(More)
Transparent PbZr(0.52)Ti(0.48)O(3) (PZT)-doped silica nanocomposites were fabricated via a modified sol-gel process. The nanocomposites were annealed at different temperatures between 740 and 800 °C in order to produce PZT crystallites with different particle sizes. X-ray diffraction analysis indicated that the embedded PZT nanoparticles were crystallized(More)
