In this paper, an efficient numerical approach is proposed for analyzing the scattering from PEC objects above a lossy half space over wide angular and frequency band. One of the principal tools for the analysis of scattering from targets located in half-space is the method of moments (MoM) and the half-space multilevel fast multipole algorithm (MLFMA). Since the surface current and the scattered...
In this paper, an efficient three-dimensional (3-D) alternating direction implicit finite-difference time-domain (ADI-FDTD) algorithm has been used to analyze the electromagnetic characteristics of ultra-wideband wireless channel. Conventional FDTD has been successfully used for the electromagnetic analysis of wireless channel. However, there is one of the major limitations of FDTD, which is that...
In this paper, we implement a hybrid combustion model which incorporates the fire simulation and solid burning together. To achieve real-time performance, GPU is used to solve the Navier-Stokes equations with CUDA programming, also used to visualize the turbulent fire. Experiment results prove our method's efficiency.
The evaluation of "closeness" between services is always crucial in the process of Web service integration and reuse. However, matching services solely based on their inputs/outputs is insufficient for developers to understand their behavioral properties or other constraints. To go beyond this limitation, services should be matched and integrated at the process level. But existing approaches...
We present a novel method using particle importance to accelerate the traditional smoothed particle hydrodynamics based fluid simulation. Reynolds number and vorticity are exploited as the new criteria to evaluate the importance for each particle. If a particle is unimportant, its current acceleration and velocity are used to update values in the next time step with the complex state updating step...
