Measurements of Ground Motion and Magnet Vibrations at the Aps
This article presents results of ground motion and magnet vibrations measurements at the Advanced Photon Source. The experiments were done over a wide frequency range (0.05-100 Hz) with the use of SM-3KV-type seismic probes from the Budker Institute of Nuclear Physics (Russia). Spectral power densities of vertical and horizontal motions of the APS hall floor and quadrupoles on regular supports ...
متن کاملNumerical simulations of Beam’s Vibrations between Stops
We present numerical simulations of vibrations of an elastic beam between two stops. The beam is clamped at one end to a vibrating device; the motion of the other end is restricted by two stops. The contact is modeled by the normal compliance condition which describes nonlinear flexible stops, and approximates the Signorini condition for rigid stops. We propose a finite element method for the n...
متن کاملthe significance of conjunction as a cohesive device in teaching writing
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
15 صفحه اولmodernist poetics as reflected in the poetry of selected modernist poets
فن شعر (poetics) که پیش از این به معنای مطالعه ی شعر و شیوه های آن بود در قرن بیستم در مفهوم گسترده به نظریه ی ادبی و مشخصه هایی که سبب پیدایش ادبیات است، اطلاق می شود. نوگرایی (modernism) بیش از آنکه از نقطه نظر زمانی دارای اهمیت باشد، گویای زمینه های فکری و اجتماعی است که تحولاتی بنیادین را در هنر و ادبیات رقم زد. تی. اس. الیوت، تی. ئی. هولم و ازرا پاوند از مهمترین نظریه پردازان نوگرایی هستند...
15 صفحه اولthe role of task-based techniques on the acquisition of english language structures by the intermediate efl students
this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...
