the purpose of this study is to correct the static shift of magnetotelluric (mt) data in one of the oil fields located in southwest of iran using time domain electromagnetic (tem or tdem) data. acquisition of the mt data has been made in the same area as the tem data was acquired at the frequency range of 0.0005-320 hertz. . a major problem in the mt method that occurs due to distribution of su...

This study investigates the free vibration of the Two-Dimensional Functionally Graded Annular Plates (2D-FGAP). The theoretical formulations are based on the three-dimensional elasticity theory with small strain assumption. The Two-Dimensional Generalized Differential Quadrature Method (2D-GDQM) as an efficient and accurate semi-analytical approach is used to discretize the equations of motion ...

Mini and micro robots, which can swim in an underwater environment, have drawn widespread research interests because of their potential applications to the clinical drug delivery, biotechnology, manufacturing, mobile sensor networks, etc. In this paper, a prototype of microrobot based on the motion principle of living microorganisms such as E. Coli Bacteria is presented. The properties of this ...

Most geometrical modelers for 3D objects use 2D interaction techniques and make little use of 3D display techniques. This interaction style forces the user to decompose 3D design operations into sequences of 2D interface operations, and there is an extra cognitive load of interpreting the 2D displays as a 3D object. While this may be acceptable for drafting applications, it has a significant ne...

چکیده تمام نما: در حال حاضر یکی از علل اصلی مرگ و میر در جهان بیماری سل می باشد. در حدود یک سوم جمعیت جهان آلوده به عامل این بیماری (mycobacterium tuberculosois ) هستند. تا کنون تلاش های بسیاری در زمینه درمان این بیماری صورت گرفته است، اما هنوز سل به عنوان یک مشکل باقی مانده است. در سالهای اخیر، پپتیدهای ضد میکروبی به عنوان عوامل درمانی امید بخش مورد توجه قرار گرفته اند. این بررسی با هدف شنا...

Researchers in bioelectromagnetics often require realistic tissue, cellular and sub-cellular geometry models for their simulations. However, biological shapes are often extremely irregular, while conventional geometrical modeling tools on the market cannot meet the demand for fast and efficient construction of irregular geometries. We have designed a free, user-friendly tool in MATLAB that comb...
