one of the major strengths of a geographic information system (gis) in geosciences is the ability to integrate and combine multiple layers into mineral potential maps showing areas which are favorable for mineral exploration. these capabilities make gis an extremely useful tool for mineral exploration. several spatial modeling techniques can be employed to produce potential maps. however, these...

this paper presents a multi-objective formulation for optimal siting and sizing of distributed generation (dg) resources in distribution systems in order to minimize the cost of power losses and energy not supplied. the implemented technique is based on a genetic algorithm (ga) and weight method that employed to obtain the best compromise between these costs. simulation results on 33-bus distri...

a characteristic of data envelopment analysis (dea) is to allow individual decision making units (dmus) to select the factor weights that are the most advantages for them in calculating their efficiency scores. this flexibility in selecting the weights, on the other hand, deters the comparison among dmus on a common base. for dealing with this difficulty and assessing all the dmus on the same s...

estimating fetal weight in utero, for better management of pregnancy and appropriate timing of delivery especially in high-risk pregnancies is necessary. our purpose to evaluate a simple method in estimating fetal weight in iranian pregnant patients and also to compare was with a previous western study. this study was carried out in arash hospital, tehran university of medical sciences in 1996-...
