آبشستگی تکیه گاه پایه پل به علت انقباض مقطع جریان و افزایش موضعی سرعت جریان در اطراف تکیه گاه پل و شکلگیری گردابه های جریان رخ میدهد. با توجه به اینکه مقطع عرضی رودخانه ها عموماً مرکب می باشند و تکیه گاه پلها ممکن است در قسمت سیلاب دشت واقع شود، بنابراین اندرکنش جریان اصلی با جریان در سیلاب دشت در حضور تکیه گاه پل الگوی پیچیده ای ایجاد می کند. بنابراین شبیه سازی عددی الگوی جریان و رسوب می تواند ...
psychological and educational findings show that preschool years play a very important role in educating and developing children. one of the dimensions of development is motor development. the survey of motor performance with respect to anthropometric characteristic is of utmost importance. thus, the aim of this study was to survey the relationship between dimensional anthropometric characteris...
Elastic constants and cross-sectional dimensions of imprinted nanolines of poly(methyl methacrylate) (PMMA) on silicon substrates are determined nondestructively from finite-element inversion analysis of dispersion curves of hypersonic acoustic modes of these nanolines measured with Brillouin light scattering. The results for the cross-sectional dimensions, under the simplifying assumption of v...
In this paper we consider the dimensions of mobile Energy and Power Management (EPM), outline an EPM design, and elaborate holistic EPM opportunities for battery-operated mobile devices. We argue that a holistic EPM design can offer significant increases for battery lifetime. Our argumentation is based on a number of cases that illustrate how energy consumption can be reduced by opportunistical...
Background and Aim: Accurate measurement of bone height and width is essential prior to dental implant placement. The method of surgery as well as, the type and size of implants are determined according to dimensions of the residual bone. The purpose of this study was to evaluate the accuracy of linear tomography in localization of the floor of nasal fossa and maxillary sinus, and to determine ...
We present a simple but powerful new probabilistic technique for analyzing the combinatorial complexity of various substructures in arrangements of piecewise-linear surfaces in higher dimensions. We apply the technique (a) to derive new and simpler proofs of the known bounds on the complexity of the lower envelope, of a single cell, or of a zone in arrangements of simplices in higher dimensions...
