Complex processes of charge transfer and phototransfer with complex changes in the distribution charges system take place chemical, electrochemical, photochemical, photoelectrochemical systems. Today, for production hydrogen methane using solar energy, biomaterials, algae, etc. are becoming relevant. A detailed analysis process shows that is largely determined by medium. In this regard, particu...

economic policy consists of various methodologies, approaches and models through which the economists devise strategies to influence the overall economy. the integration of theoretical and practical frameworks provides the ground for emerging new models which are a part of economic system of the countries.each economic model is a combination of specific methodology, theoretical bases and specia...

in this paper a guided tabu search (gts) is utilized for optimal nodal ordering of finite element models (fems) leading to small profile for the stiffness matrices of the models. the search strategy is accelerated and a graph-theoretical approach is used as guidance. the method is evaluated by minimization of graph matrices pattern equivalent to stiffness matrices of finite element models. comp...
