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...

in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...

در این پژوهش، مقادیر دبی های رودخانه های استان اردبیل با بهره گیری از مدل شبکه های عصبی مصنوعی و نیز با استفاده از توابع و امکانات نرم افزار matlab، مدل سازی شد. بدین منظور، از آمار بلند مدت ایستگاه های هیدرومتری رودخانه های این استان و برخی پارامترهای اقلیمی (دما، رطوبت نسبی، بارندگی و فشار) ایستگاه های سینوپتیک موثر بر میزان دبی های حوضه های این استان در طول دوره آماری 30 ساله (سال آبی 58-135...

مقدمه بسی جای شگفتی است که تعداد مقالات و تحقیقات مربوط به فیلم بسیارکم است زیراکه زبان آموزان علاقه بسیاری به یادگیری با فیلم ها دارند. در این پایان نامه سعی شده است که به بررسی یادگیری شنوایی بهتردر دانش اموزان پرداخته شود اما این بار با ابزاری متفاوت که همان لغات پرتکرار فیلم هاست که توسط نرم افزاری که بدین منظور طراحی شده به دست می آیند. طرح مسئله مدرسین معمولا علاقه ای به استفاده و بکا...
