چکیده به دلیل کاربرد وسیع موتورهای dc ، کنترل وضعیت یا سرعت آنها اهمیت فراوانی پیدا می کند. در این مقاله هدف، ارائه روشی جدید برای کنترل هوشمند وضعیت موتور dc تحریک جداگانه با استفاده از شبکه های عصبی مصنوعی است. برای این منظور ازکنترلر شبکه عصبی narma-l2 استفاده شده است. در کنترل وضعیت با استفاده از شبکه عصبی، وضعیت مبنای شبکه عصبی همان وضعیت ورودی (مطلوب) در نظر گرفته شده است و پس از انطباق و...
We have showed previously that the Fourier transform is an isometric isomorphism on L2 = CcR ∩ L2Rn. In particular, we have a ∀u ∈ L2 ||u||0 = ||û||0 Parseval relation b ∀u,v ∈ L2, u,v0 = û, v̂0 Plancherel relation The results (a) and (b) hold for every test function, and since the test functions are dense in L2Rn, they extend to L2Rn by continuity. Then the Fourier transform can...
در این پروژه تلاش شد تا با سنتز لیگاند کربوکسامیدی n-(2-پیرازین)-¬فوران-2-کربوکسامید (l1) حاوی حلقه¬های آروماتیک فوران و پیرازین به بررسی تاثیر برهم¬کنش¬های بین مولکولی این حلقه¬ها در انباشتگی ساختار کریستالی پرداخته شود. در ادامه با سنتز و بررسی ساختار کمپلکس¬های سری هالید جیوه(??) شامل (1) [hgcl2(l1)] و [hgbr2(l1)] (2)و [hgi2(l1)2] (3)، برهم¬کنش¬های مربوطه در ساختارهای کریستالی مورد بررسی قرا...
in this paper, g-dual function-valued frames in l2(0;1) are in-troduced. we can achieve more reconstruction formulas to ob-tain signals in l2(0;1) by applying g-dual function-valued framesin l2(0;1).
According to a basic prediction made by the Revised Hierarchical Model (RHM), at early stages of language acquisition, strong L2-L1 lexical links are formed. RHM predicts that these links weaken with increasing proficiency, although they do not disappear even at higher levels of language development. To test this prediction, two groups of highly proficie...
The present study investigated any probable relationship between theidentity processing styles and L2 literacy of advanced Persian EFL learners. Theparticipants included 160 (female = 109, male = 51) advanced EFL Iranian learners.The instruments used included a simulation of the TOEFL iBT test, measuring theparticipants’ L2 literacy-related proficiency, reading, and writing, and the identitysty...
Sentence Processing Among Native vs. Nonnative Speakers: Implications for Critical Period Hypothesis
The present study intended to investigate the processing behavior of 2 groups of L2 learners of English (high and mid in proficiency) and a group of English native speakers on English active and passive reduced relative clauses. Three sets of tasks, an offline task, and 2 online tasks were conducted. Results revealed that the high-proficiency group’s performance was the same as that of the nati...
the effect of motivational self-regulatory strategies on l2 learners’ achievement has scarcely been examined within the context of our country, iran. this study is concerned with examining the relationship between motivational self-regulatory strategies and their l2 reading and l2 writing achievement. it also explores the relationship of motivational self-regulatory strategies and use of langua...
L2 Narrative Identity as Drama: Exploring Links Between L2 Learning Experience and the Ideal L2 Self
Recent studies elaborating on the L2 learning experience component of Motivational Self System (Dörnyei, 2005, 2009), especially through a narrative identity perspective, mark new direction in motivation research. This paper extends this work by exploring connection between and ideal self components. Emerging from different theoretical origins, these components have proved difficult to reconcil...
Both the Human papillomavirus (HPV) major (L1) and minor (L2) capsid proteins have been well investigated as potential vaccine candidates. The L1 protein first oligomerizes into pentamers, and these capsomers assemble into virus-like particles (VLPs) that are highly immunogenic. Here we examine the potential of using HPV type 16 (HPV-16) L1 subunits to display a well-characterized HPV-16 L2 epi...
