The performance of an acoustic absorbent lining can be significantly related to the shape of the introduced holes inside the lining, the general shape of holes can be designed by the topology optimization. In this paper, the finite element model of an acoustic absorbent lining is built, the acoustic and structure response characteristics are performed by used of the direct finite element method(FEM)...
Grid workflow scheduling problem has been a research focus in grid computing in recent years. Various deterministic or meta-heuristic scheduling approaches have been proposed to solve this NP-complete problem. These existing algorithms, however, are not suitable to tackle a class of workflows, namely the time-varying workflow, in which the topologies change over time. In this paper, we propose an...
