In this study, the seismic interaction of surface foundations and underground cavities was investigated. For this purpose, a parametric study of geometric dimensions of the foundation and cavity, their location, and the effect of the interaction between surface foundations and underground cavities was evaluated. The variable parameters include the ratio of the overburden height to the foundatio...

in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...

Abstract The article is based on the theory of computational fluid dynamics. We qualitatively analyse difference between total pressure windward side and leeward by numerical method, compare wind environment around ground floor non-overhead courtyard building with same width height. distribution velocity field, field trace map fully overhead not completely are obtained. By introducing CFD simul...

The tree-layout problem is to compute the coordinates of nodes of a tree so that the tree, when drawn on a piece of paper, appeals to human understanding. The tree-layout problem, which seems inherently sequential at the first glance, can be solved with a data-parallel algorithm. It takes O (height * log width ) time on width processors when proper communication links between processors are ava...
