a primary uses from iran rangelands is livestock grazing and the major livestock is sheep. sheep grazing on the slopes above 60%, because of using a lot of energy for grazing operation, caused to not only reduces livestock performance but also increases the risk of erosion. sheep grazing in an area where more than five kilometers away from water sources, due to the prolongation of the march rou...

the infomax algorithm is a popular method in blind source separation problem. in this article an extension of the infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-gaussian distributions. this ability is the results of using two different nonlinear functions and new coefficients in the learning rule. in this paper we show how we can use the distribution...

introduction renal transplant is the best treatment of choice for patients with end-stage renal disease (1). annually, about 17000 patients receive deceased or living donor transplants, which help them promote health and self-efficacy (1-2). however, despite advances in transplant technology, patients face a number of post-operative challenges, which might lead to stress in patients, including ...

in recent years, there has been a fast growth in wind energy conversion system (wecs). there are two general types of wind turbines in wecs: fixed speed wind turbines and varying speed wind turbines.permanent magnet synchronous generator (pmsg) is one of the most attractive generators for the varying speed turbine wecs.in this paper, a fuzzy controller is proposed to control the current source ...

this contribution determines suitable fingerprinting properties for sediment source discrimination within theamrovan and atary catchments in semnan province, iran. these catchments are representative of a range of geology formations and should therefore provide a meaningful basis for a general assessment of the degree of sediment source discrimination afforded by a range of fingerprint properti...

different approaches of source apportionment of dust fractions have been reported world-over. predicting source categories within receptor chemical profiles using regression and factor analysis using pca has been reported to evaluate possible source/routes of air pollution mass. the present study is focused on the application of all three approaches to investigate higher degrees of significance...
