در این تحقیق هشت ترکیب جدید بیس فسفرآمیدیتی با فرمول کلی r2p(o)(c6h4)p(o)r2 که r شامل گروه های مورفولین (l1)، پی پیریدین (l2)، هگزامتیلن (l3)، گروه فنیل (l4)، آریلوکسی (l5)، دی اتیل(l6)، متوکسی (l7)و اتوکسی (l8) سنتز شد. همچنین کمپلکس هایی از این ترکیبات با نمک فلزات واسطه eu(no3)3.6h2o ، er(no3)3.6h2o ، eucl3.6h2o، ercl3.6h2o و cecl2.7h2o تهیه گردید. افزون بر آن برخی از لیگاندهای نیکوتین آمید ...
this experimental study examined the effectiveness of using focused and unfocused tasks on iranianintermediate efl learners’ performance in producing noun, adjective, and adverb clauses. in addition,the aim of this study was to explore the effects of form-focused instruction and the feedback studentsreceived from their teacher after doing focused grammar tasks. data consisted of the scores ofth...

A classical theorem of C. Fefferman [3] says that the characteristic function of the unit disc is not a Fourier multiplier on L(R) unless p = 2. In this article we obtain a result that brings a contrast with the previous theorem. We show that the characteristic function of the unit disc in R is the Fourier multiplier of a bounded bilinear operator from L1(R) × L2(R) into L(R), when 2 ≤ p1, p2 <...
iii this study was an attempt to determine the effect of task-based approach vs. traditional approach on the narrative and expository writing of the iranian efl learners. there were two control groups as well as two experimental ones in the current study. in the two control groups namely g1 and g2 narrative and expository writing were taught respectively using the traditiona...
Given compactly supported 0 ≤ f, g ∈ L1(R), the problem of transporting a fraction m ≤ min{‖f‖L1 , ‖g‖L1} of the mass of f onto g as cheaply as possible is considered, where cost per unit mass transported is given by a cost function c, typically quadratic c(x,y) = |x − y|/2. This question is shown to be equivalent to a double obstacle problem for the Monge-Ampère equation, for which sufficient ...

We summarize the involvement of our CEMI team in the “NLI Shared Task 2017”, which deals with both textual and speech input data. We submitted the results achieved by using three different system architectures; each of them combines multiple supervised learning models trained on various feature sets. As expected, better results are achieved with the systems that use both the textual data and th...
