Like other structures, shallow domes have imperfections from the prescribed values obtained by specifications during the construction process. Specifications define some tolerance values for imperfections. Despite consideration of these values, the critical load of a dome varies for each imperfection pattern. So the reliability plays an important role in domes safety. Theoretical evaluation pro...

Issues of load combinations of earthquakes and heavy trucks are important contents in multihazards bridge design. Current load resistance factor design (LRFD) specifications usually treat extreme hazards alone and have no probabilistic basis in extreme load combinations. Earthquake load and heavy truck load are considered as random processes with respective characteristics, and the maximum comb...

Emotion and cognition are both considered influential factors in language learning. In this study, the role of "emotioncy" (which is a combination of emotion and frequency) in the cognitive load and sentence comprehension of a group of language learners was examined. Emotioncy includes emotions that are evoked by the senses. To this aim, 200 English as a foreign language (EFL) learners were ask...

Let G be a graph, and denote by Q(G)/2t the hypercube of dimension log2|G|-t. Motivated by the problem of simulating large grids by small hypercubes, we construct maps f:G→Q(G)/2t, t ≥1, when G is any two or three dimensional grid, with a view to minimizing communication delay and optimizing distribution of G-processors in Q(G)/2t. Let dilation(f) = max{dist(f(x),f(y)): xy E(G)}, where "dist"...

We propose a general strategy of many-to-one embedding of tree-related graphs into hypercubes. These tree-related graphs include complete binary tree (CBT), mesh of trees (MOT), pyramid and so on. This strategy evenly distributes the same level nodes of a tree-related graph to the nodes of a hypercube. This distribution is a great advantage because the same level nodes are always activated simu...
