one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
abstract this study set out to compare the effect of modality of presentation (subtitled vs. auditory) in the comprehension of verbal content of documentary films among iranian efl students. to this end, (30 male 30 female) students were chosen from two schools. after their homogeneity was established, the students attended the listening sessions to watch five documentary films over t...
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...
Pemanfaatan potensi energi angin telah menghasilkan perkembangan pada perancangan generator magnet permanen 18 slot 16 pole. Pada pole hanya mampu efisiensi sebear 70%. Penelitian ini bertujuan untuk menaikkan dari tersebut. paper akan melakukan percobaan dengan memasukkan inputan material melihat pengaruh permanent Ceramic Ferrite, PM12: Br 1.2 mur 1.0, Neodymium Iron Boron, dan Samarium cobal...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
Permanent Magnet Synchronous Motors (PMSMs) are increasingly being used and required to satisfy noise vibration specifications. Thus, it is necessary develop design guidelines for electric motors that consider response as a key output of the design. This work shows influence main parameters regarding PMSMs: number slots poles. First, in natural frequencies analysed by Finite Element calculation...
In this paper, a new flux-intensifying fault-tolerant permanent magnet synchronous motor (FI-FTPMSM) is proposed to improve sensorless operating capacity under multimode operation including fault conditions. Most previous studies regarding motors aim capability but suffer the saliency characteristic problem, which unfavorable for control. study, an active strategy developed by considering in de...
In this study, the effects of ratio a motor’s axial length to its pole pitch on efficiency, magnetic flux density distribution, torque, torque/weight, and motor volume were investigated in an outer-rotor (hub) brushless direct current motor. The weight electrical machine affects output power, efficiency it is advantageous design electric at appropriate power high with volume. Therefore, aim stu...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
