به منظور بررسی تغییرات دمای کمینه و بیشینه، بارش و شدت خشکسالی (شاخص SPI) استان گلستان طی دوره 2045-2016 نسبت به دوره 2015-1986، خروجی مدل‌های HadCM3 و ECHO-G تحت سناریو A2 توسط مدل LARS-WG در 15 ایستگاه هواشناسی ریزمقیاس شد. توانایی هر دو مدل در پیش‌بینی پارامترهای مورد نظر با استفاده از آماره‌های مختلف مناسب ارزیابی شد. مطابق پیش‌بینی مدل‌های HadCM3 و ECHO-G، میانگین سالانه دمای کمینه به ترتی...

chapters 1 and 2 establish the basic theory of amenability of topological groups and amenability of banach algebras. also we prove that. if g is a topological group, then r (wluc (g)) (resp. r (luc (g))) if and only if there exists a mean m on wluc (g) (resp. luc (g)) such that for every wluc (g) (resp. every luc (g)) and every element d of a dense subset d od g, m (r)m (f) holds. chapter 3 inv...

we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...

let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...

abstract the purpose of this study was to find out the effect of applying the principles of group-dynamic assessment (g-da) on learning of conditional structures in english by iranian efl learners at the intermediate level, which according to the formal educational system in iran, includes students who are in their second year of studying in high schools of koohdasht city. this study was a qua...
