Terrain is the most critical factor in the prediction of radio wave propagation. Using software predicts radio wave propagation produces large calculation and low speed. Approximate techniques are proposed here for ray-tracing systems used to predict radio propagation. In this paper, two-dimensional discrete FFT of the terrain and filter smoothing are studied. It is shown that within the allowed computational...
Sensitivities of through-Si-via (TSV) interconnects to the process parameters are investigated numerically in this paper. Some important parameters of the coupled interconnects are examined and compared in detail, such as silicon conductivity of the substrate and radii of the TSVs, etc., where MOS effects are treated appropriately. The emerging materials, carbon nanotube (CNT) based TSVs are also...
Cheng's refined theory is extended to investigate the thermoelastic plate posting inside Winkler Foundation under steady temperature, and the refined analyses for the thermoelastic plates posting inside the Winkler Foundation under steady temperature is deduced systematically and directly from linear thermoelastic theory and Lur'e method. Expressions are introduced for all the displacements and stress...
With the deepening teaching reform and development of informational management technology, the establishment and application of information systems management has become the inevitable requirement of vocational college teaching management. This article described the importance and necessity of informational teaching management in vocational college, analyzed the current situation and problems of informational...
For piezoelectric semi-infinite strips with mixed edge-data, the Betti-Rayleigh reciprocal theorem and the general solution of plane piezoelectricity are applied in a novel way to obtain the appropriate edge conditions accurate to all order. A decay analysis technique is used to establish necessary conditions which the prescribed data on the edge of the strips must satisfy in order that it should...
