Analysis of Anti-seepage Effect of Masonry Gravity Dam Repaired by Geomembrane by WANG Libo, CEN Weijun, ZHENG Changhai

“…In view of the seepage of the dam body and dam foundation of a dangerous masonry gravity dam,this paper puts forward the seepage repair scheme of laying geomembrane on the dam surface and strengthening the curtain of the dam foundation,calculates the seepage field of the dam under multiple working conditions by the finite element method for obtaining the distribution of the equal head line,the height of the seepage line,the seepage gradient and the seepage flow of the dam,and emphatically demonstrates and analyzes the anti-seepage effect of geomembrane and curtain.The results show that:The geomembrane on the upstream face of the dam can significantly reduce the water head,the position of the dam seepage line after laying with the geomembrane is low,and the seepage flow of the dam is small.The curtain after reinforcement of dam foundation also has a good anti-seepage effect,which effectively limits the seepage of dam foundation,and the seepage gradient of curtain is smaller than the allowable gradient.Therefore,it is reasonable and feasible to use geomembrane combined with curtain reinforcement to repair the seepage of masonry gravity dam.…”

Improved artificial fish-swarm algorithm based on adaptive vision for solving the shortest path problem by Xian-min MA, IUN L

“…To solve basic artificial fish-swarm algorithm(AFSA)’s drawbacks of low convergence rate in the latter stage,a large amount of computation and easiness of trapping in local optimal solution,caused by the constant vision of the artificial fish,an improved artificial fish-swarm algorithm based on adaptive vision(AVAFSA) was proposed.The improved algorithm only adjusted the vision of the preying behavior of artificial fish to make the vision gradually decrease with the increase of the number of iterations of the algorithm.When the value became less than half the initial value,it made the value be equal to half the initial value.The proposed improved artificial fish swarm algorithm was applied to the static shortest path problem based on road network to provide customers with the best path.Simulation results depict the improved algorithm has higher convergence rate,a smaller amount of calculation,and is more accurate and stable than the basic AFSA and ant colony optimization(ACO).…”

Directional entropy based model for diffusivity-driven tumor growth by Marcelo E. de Oliveira, Luiz M. G. Neto

“…In our formulation, the tumor aggressiveness and morphological behavior is tissue-type dependent, i.e. alterations in white and gray matter regions (which can e.g. be induced by normal aging in healthy individuals or neurodegenerative diseases) affect both tumor growth rates and their morphology.The feasibility of this new conceptual approach is supported by previous observations that the fractal dimension, which correlates with the Shannon entropy we calculate, is a quantitative parameter that characterizes the variability of brain tissue, thus, justifying the further evaluation of this new conceptual approach.…”
