this research is a study on indicators of listening instruction in iranian english as a foreign language (efl) curriculum at guidance school and high school educational levels. this thesis aims at determining: a) the indicators of listening instruction at guidance school and high school efl curriculum. b) the indicators of listening instruction in irans guidance school and high school efl curri...
AIM Surgical outcome for giant intracranial aneurysms (GIA) is suboptimal. Reasons for higher complication rates in large and GIA surgery are the occlusion of perforators or parent arteries during aneurysm clipping, or prolonged temporary occlusion of main arteries. In this article, results of clipping of large and GIAs of anterior circulation are presented. MATERIAL AND METHODS Ten patients ...
the purpose of this study is to describe and determine the relationship between relationship marketing, customer satisfaction and intention to revisited in mashhad’s women aerobics clubs. to do this,300 randomly customers from women aerobic clubs were chosen and data was collected through kim relationship marketing questionnaire(2008) and ?=0.92, lim satisfaction questionnaire(2008) and ?=0...
In this paper, the Peak-to-Average Ratio reduction in OFDM systems is implemented by the Adaptive Active Constellation Extension (ACE) technique which is more simple and attractive for practical downlink implementation purpose. However, in normal constellation method we cannot achieve the minimum PAR if the target clipping level is much below than the initial optimum value. To get the better of...
Orthogonal frequency division multiplex/offset QAM (OFDM/OQAM) has been proven to be a promising multi-carrier modulation (MCM) technique for the transmission of signals over multipath fading channels. However, OFDM/OQAM has also the intrinsic disadvantage of high peak-to-average-power ratio (PAPR) that should be alleviated. This paper focuses on the reduction of the clipping noise and out-of b...
the following question poped up: is there any relationship between iranian high school efl learners reading comprehension and listening comprehension? then the following null hypothesis (ho) was developed to the test the above, mentioned question. "there is no relationship between high school efl learners reading comprehension and listening comprehension. for nearly 16 weeks, the experimental g...

General relativity is notoriously difficult to interpret. A "return to the mothers" is proposed to better understand the gothic-R theorem of the Schwarzschild metric of general relativity. It is shown that the new finding is already implicit in Einstein's equivalence principle of 1907 and hence in special relativity (with acceleration). The TeLeMaCh theorem, named onomatopoetically after Telema...
This paper work focuses on performance analysis of PAPR reduction of orthogonal frequency division multiplexing (OFDM) using amplitude clipping & filtering based design. Now a days one of the most proficient multi-carrier transmission techniques widely used today is orthogonal frequency division multiplexing (OFDM) which has been implemented by the next generation wireless communication technol...
