در این تحقیق ابتدا پارامترهای ژئومکانیکی سنگ های میزبان خط جنوبی مترو اصفهان بررسی شده است. سپس هدف از ابزاربندی تشریح شده و ابزارهای نصب شده در خط مذکور معرفی و برخی از نتایج ابزارها، ارائه شده است. روش های انجام تحلیل برگشتی و بهینه سازی آن بیان و مزایا و معایب هر روش بررسی شده است. در ادامه به نحوه مدل سازی عددی به صورت سه بعدی اشاره شده است. تحلیل برگشتی برای تعیین پارامترهای مدول تغییر شکل...
background: tangential irradiation of intact breast is one of the most common procedures performed in any radiotherapy center. this method is performed by using 2d and 3d treatment planning. the aim of this study was to compare 2d with 3d plans in breast conserving radiotherapy. homogeneity of isodose, and lung received dose were compared. materials and methods: twenty patients with breast canc...
a truly meshless local petrov-galerkin (mlpg) method is developed for solving 3d elasto-static problems. using the general mlpg concept, this method is derived through the local weak forms of the equilibrium equations, by using test functions, namely, the heaviside function. the moving least squares (mls) are chosen to construct the shape functions, for the mlpg method. the penalty approximatio...
ایجاد گردابهها در دهانهی ورودی سرریزهای نیلوفری میتواند باعث کاهش ضریب دبی و کارایی نامناسب سرریز گردد. بنابراین استفاده از تیغههای گردابشکن باعث کاهش این گردابه ها شده و کارایی سرریز را افزایش میدهد. در این تحقیق هدف، مدلسازی عددی جریان عبوری از سرریز نیلوفری و بررسی تأثیر تیغههای گردابشکن در جریان سرریز نیلوفری به کمک مدل ریاضی flow-3d میباشد. بنابراین در این تحقیق مدلسازی سرریز در...
in this study, the experimental analysis on the bare hull resistance coefficient of submarine at snorkel depth is represented. the experiments are conducted in marine laboratory of admiral makarov university. the results are presented for surface condition and snorkel condition. snorkel depth is regarded equal to one diameter of submarine hull beneath the water surface as usual in submarines. p...

This work aims at figuring out the spatial relationships between the geophysical and geological models in a case study pertaining to copper-sulfide mineralization through an integrated 3D analysis of favorable target. The Ghalandar Skarn-Porphyry Cu Deposit, which is located in NW Iran, is selected for this research work. Three geophysical surveys of direct current electrical resistivity and in...
Slope stability analysis is one of the most important problems in mining and geotechnical engineering. Ignoring the importance of these problems can lead to significant losses. Selecting an appropriate method to analyze the slope stability requires a proper understanding of how different factors influence the outputs of the analyses. This paper evaluates the effects of considering the real geom...
Numerous studies have shown the positive effects of rosmarinic acid on the nervous system. Rosmarinic acid as a herbal compound with anti-inflammatory effects can prevent the destructive effect of inflammation on the nervous system. Furthermore, various studies have emphasized the advantages of three dimensional (3D) culture over the two dimensional (2D) culture of cells. In this study, thermos...
normal 0 false false false en-us x-none fa background: the angular dependency of response for tld cards may cause deviation from its true value on the results of environmental dosimetry, since tlds may be exposed to radiation at different angles of incidence from the surrounding area. objective: a 3d setting of tld cards has been calibrated isotropically in a standard radiation field to eval...
