In order to solve the extra power consumption caused by reducing complexity in cooperative relay networks, an optimized power allocation algorithm is proposed for the efficient incremental selection hybrid decode-amplify forward (ISHDAF) scheme. In the ISHDAF scheme, the transmission efficiency is improved by optimizing the power allocation, which is constrained by constant total power. And the outage...
In this paper, a novel approach is proposed for shape classification based on the semi-supervised framework. For shape similarity-measuring problem, in order to avoid solving an NP problem produced by finding some affine transformation and to enhance its robustness for local changes of the shapes, we switch to compute an energy index defined by the degree of segmentation. The corresponding segmentation...
This paper presents an up-to-date survey on the application of Smoothed Particle Hydrodynamics (SPH) method in fluid simulation. As a pure Lagrangian method, it has a wide range of applications in computer graphics. We summarize it from key issues of kernel function, neighborhood search, boundary conditions, time integral to algorithm application in diverse fluids, including bubble, fluid-solid interaction,...
