Distribution systems can be operated in multiple configurations since they are possible combinations of radial and loop feeders. Each configuration leads to its own power losses and reliability level of supplying electric energy to customers. In order to obtain the optimal configuration of power networks, their reconfiguration is formulated as a complex optimization problem with different objec...

this paper using generalized roeger's model calculated the lerner index for iranian active industries in 4-digit isic codes during the period 1995-2007. the findings indicate that the lerner index has been between 8 to 16 percent in 38 industries among 131 ones. the index also in different industries shows that more than 50 percent of iranian industries have monopolistic power such that th...

Power index research has been a very active field in the last decades. Will this continue or are all the important questions solved? We argue that there are still many opportunities to conduct useful research with and on power indices. Positive and normative questions keep calling for theoretical and empirical attention. Technical and technological improvements are likely to boost applicability.

The Shapley-Owen power index is reviewed and an algorithm for its computation in two-dimensional spatial voting models is presented. The Shapley-Owen values for ideal point distributions representing the UN Security Council, Bretton Woods institutions, US legislators, as well as Monte Carlo data are considered

The paper presents a simplified approach to evaluate the risk index whose minimization results in the enhancement of power system reliability. The risk indices evaluated in the paper includes mainly LOLP (loss of load probability) and LOLE (loss of load expectation) with more emphasis on LOLE as it indicates the expected number of days in the specified periods in which the daily peak load will ...

In this report, we drew on data from an ongoing longitudinal study that began in 1978 (Hauser, Powers, Noam, Jacobson, Weiss, & Folansbee, 1984). Focusing on late, young-adult life among individuals who were psychiatrically hospitalized during adolescence, we examined markers of resilience empirically defined in terms of adult success and well-being. The study includes a demographically similar...

With ever increasing energy demand no site for setting up power plant can be left un-harnessed. Therefore, in the present work a methodology based upon the combination of graph theory and matrix method is developed so that an site may be evaluated in terms of best suitability for setting up a power plant. Factor responsible for best operational performance of a power plant are identified and ev...

Power distributions of voting games in which only certain coalitions are allowed, due to the fact that the players are spread across an ideological spectrum, are considered. The paper extends Edelman’s model [Edelman, P., 1997. A note on voting. Math. Soc. Sci. 34, 37–50] concerning ́ allowable coalitions. The Markov-Polya index is introduced as a parametrized family of power indices which has E...
