this article is devoted to the simultaneous optimization of shape and topology of shell structures. the optimum shape is obtained together with the optimum layout for the reinforcement layers at the both sides of the shell surface. to solve this problem the finite element method is employed. it is assumed that each element is comprised of a porous media with microscopic rectangular voids where ...

As an important component of road transportation, the bus terminal has always been focus research. Therefore, this article uses a combination quantitative and qualitative analysis to study Zhengding third-level from perspective layout analysis. On basis actual investigation, relevant indicators scale are calculated. At same time, three functional areas process flow lines inside passenger statio...

In this paper, application of a multi-objective evolutionary algorithms is explored for solving multi-objective placement, packing, or layout problems. Placement problems are optimization problems concerned with finding an optimal arrangement of multiple items in a large containing region while satisfying prescribed requirements and constraints. This study is applied to the configuration design...

Programs accessing disk-resident arrays, called out-of-core programs, perform poorly in general due to an excessive number of I/O calls and insufficient help from compilers. In order to alleviate this problem, we propose a data layout optimization in this paper. Experimental results provide evidence that our method is effective for out-of-core nests whose data sizes far exceed the size of memory.
