Objective: In this study, psychometric qualities of multidimensional perfectionism scale (MPS) were evaluated. Methods: Persian version of perfectionism inventory was completed by 48 adults (24 females and 24 males). The sample was selected by cluster random sampling from Sarcheshmeh adult inhabitants. Reliability of the scale was assessed by calculating Cronbach's alpha coefficient. Then 26...

Object-oriented load flow modeling is presented for both radial and weakly meshed distribution systems. An OO algorithm based on the Newton–Raphson technique is proposed. In the object oriented formulation, some approximations to the full Jacobian matrix are introduced. Consequently, a detailed study of the convergence characteristics of the proposed object oriented algorithm is presented and s...

in data envelopment analyze (dea) the scale efficiency in the input-oriented ccr model is less than or equal to the scale efficiency in dea based on the fractional analysis (dea-r). also, the scale efficiency in case of multiple inputs and one output and vice versa the scale efficiencies are equal in dea and dea-r. in this paper, first, dea-r model with weight restrictions when there is relativ...
