رشد سریع شهرها و روندصنعتی شدن ، مشکلات زیست محیطی زیادی را در بسیاری از شهرهای جهان ایجاد کرده است.آگاهی از روند تغییرات پوشش و کاربری اراضی طی دوره های زمانی طولانی برای برنامه ریزان و مدیران به منظور ارزیابی و پیش بینی مشکلات ناشی از این تغییرات بسیار با اهمیت است. سنجش از دور ابزار موثری برای پایش تغییرات پوشش اراضی درمناطق شهری و حوالی آن می باشد. شهر یاسوج در چند دهه اخیر بواسطه رشد و بدن...

background: it is estimated that major depression disorders constitute 8.2% of years lived with disability (ylds) globally. the repetitive transcranial magnetic stimulation (rtms) and electroconvulsive therapy (ect) are two relative common interventions to treat major depressive disorders, especially for treatment resistant depression. in this study the cost- effectiveness and cost-utility of r...
the aim of this study was to estimate suspended sediment by the ann model, dt with cart algorithm and different types of src, in ten stations from the lorestan province of iran. the results showed that the accuracy of ann with levenberg-marquardt back propagation algorithm is more than the two other models, especially in high discharges. comparison of different intervals in models showed that r...
In this paper, at first we define the concepts of response function and accessible states of a complete residuated lattice-valued (for simplicity we write $mathcal{L}$-valued) tree automaton with a threshold $c.$ Then, related to these concepts, we prove some lemmas and theorems that are applied in considering some decision problems such as finiteness-value and emptiness-value of recognizable t...
A new technique presents to improve the performance of dynamic voltage restorer (DVR) for voltage sag mitigation. This control scheme is based on cuckoo search algorithm with tree fuzzy rule based classifier (CSA-TFRC). CSA is used for optimizing the output of TFRC so the classification output of the network is enhanced. While, the combination of cuckoo search algorithm, fuzzy and decision tree...
