We investigate the transfer of power between different scales and coupling of modes during non-linear evolution of gravitational clustering in an expanding universe. We start with a power spectrum of density fluctuations that is exponentially damped outside a narrow range of scales and use numerical simulations to study evolution of this power spectrum. Non-Linear effects generate power at othe...

This paper presents a methodology for operational and economic characteristics based evaluation and selection of a power plant using Graph theoretic approach. A universal evaluation index on the basis of Operational and economics characteristics of a plant is proposed which evaluates and ranks the various types of power plants. The index thus obtained from the pool of operational characteristic...

Power indices of weighted majority games are measures of the effects of parties on the voting in a council. Among the many kinds of power indices, Banzhaf index, Shapley-Shubik index and Deegan-Packel index have been studied well. For computing these power indices, dynamic programming algorithms had been proposed. The time complexities of these algorithms are O(nq), O(nq), and O(nq), respective...

Model credibility index is defined to be a sample size under which the power of rejection equals 0.5. It applies goodness-of-fit testing thinking and uses a one-number summary statistic as an assessment tool in a false model world. The estimation of the model credibility index involves a bootstrap resampling technique. To assess the consistency of the estimator of model credibility index, we in...

This paper develops a risk-based integrated index that reflects power system reliability and security both directly and indirectly. Direct characteristics may express the risk to not fully supply load at various load levels and contingencies. Indirect characteristics address such undesirable conditions as circuit overloads, voltage problems, low stability margins, area interchange violations, i...

agricultural mechanization is a method for transiting from traditional agriculture towards industrial and sustainable one. due to the limitation of natural resources and increasing population we need to have economical production of agricultural crops. for reaching this destination; agricultural mechanization has a remarkable role. so it is necessary to have an extensive view for mechanization,...

In this research, called the “the maintenance index,” was proposed to evaluate the reliability of nuclear power plant safety systems by taking into account periodic maintenance of the systems. The change in reliability as a result of changing activity is estimated by this index. The Maintenance Index offers a more comprehensive evaluation of nuclear power plant safety. * Corresponding author, E...

The concept of Shapley values was first introduced into the game theory by Shapley [1953] in the framework of transferable payoffs, playing an important role in the game theory. According to a standard textbook on game theory it is interpreted as in what follows. “Suppose that all the players are arranged in some order, all orders being equally likely. Then player i’s Shapley value is the expec...
