This article presents the results of studying temperature distribution in process thermo-frictional cutting titanium alloy Ti-5553. The was simulated using Machining module DEFORM 3D software package based on finite element method. It found that when off Ti-5553, depending geometry circular saw, "disk-workpiece" contact zone reached T = 800 ÷ 1130 °C, and its propagation into depth workpiece 0....
Although second language (L2) writing is a popular topic among SLA researchers, the fact that L2 has potential to act as scaffold for speaking accuracy often overlooked. This study's objective was provide empirical evidence can be used improve of oral discourse. Twenty-three Novice and 21 Intermediate university learners Russian participated in study. They completed text reconstruction task by ...
Critical pedagogy (CP) empowers L2 learners to have a voice in the classroom and in the society. This study was an attempt to investigate whether the current classroom discourse in Iran can endow the L2 learners with a critical awareness to actively transform their learning processes and creatively engage in collaborative dialogues to construct new knowledge. To this end, the discou...
This paper aims at providing a comprehensive review of previous research on second language (L2) writing. Major issues and the relevant findings from five areas of inquiry into L2 writing are presented, namely, L2 writers’ characteristics, the L2 writing process, L2 writing feedback, L2 writing instruction, and L2 writers’ texts. It is found that L2 writing is quite a complex process which invo...
Based on the controversial beliefs among L2 teachers about effective corrective feedback (CF) strategies, recast and prompts as 2 kinds of CF have drawn the attention of L2 researchers(e.g., Braidi, 2002; Iwashita, 2003; Loewen & Philp, 2006; Panova & Lyster, 2002; Sheen, 2004). Despite these numbers of studies, debate continues to exist about their usefulness as a CF technique. Whereas recasts...
the idea is growing among educators that thinking skill needs to be given a direct attention. on one hand, critical thinking is supposed to broaden students’ thinking in all regards (schafersman, 1991); and on the other hand learners’ attitudes towards the second language can affect both their performance in the class and their final accomplishment. to this end, the present study started with t...
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...
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...
