This volume addresses the hottest topics in computer-aided materials science and engineering. It covers a wide range of issues in this area: including computer-aided materials technology, engineering design and manufacturing informatization, etc. Researchers in the field are sure to glean cutting-edge information from this volume.This volume includes 134 selected papers from the 2011 International Conference on Computer-aided Material and Engineering held in Hangzhou, China, in March 2011. The varied subject matter includes: dynamic analysis of cutter head systems in tunnel boring machines, video vehicle detection based on local features, a semantic metadata describing video information based on ontology, the product of two B-spline functions, parallelizing network coding using CUDA, stochastic simulation of bus traveling time, query optimization based on data provenance, cloud computing: cloud security to trusted cloud, and an efficient data stream clustering algorithm based on dynamic grids. Editors are Tian and Xu, for whom no credentials are given.
