degradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses

در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...

A simple and fast flip angle calibration method

Introduction Quantitative MR techniques such as variable flip angle (VFA)[1] , DESPOT1 [2], quantitative T 2 [3] etc. rely on the accuracy with which the true flip angle is known. Although spatial inhomogeneity of flip angles is expected at high fields (>1.5T) due to B1 field inhomogeneities and uneven slice profiles, accurate estimates of true flip angle are important even at lower field stren...

Modeling of capacitance and sensitivity of a MEMS pressure sensor

In this paper modeling of capacitance and sensitivity for MEMS capacitive pressure sensor is presented. In capacitive sensor the sensitivity is proportional to deflection and capacitance changes versus pressure. Therefore first the diaphragm displacement, capacitance and sensitivity of sensor with square diaphragm have been modeled and then simulated using finite element method (FEM).  It can b...

Biaxial Angle Sensor Calibration Method Based on Artificial Neural Network

With regard to the nonlinearity, installation errors and other uncertainties existing in biaxial inclination sensors of borehole inclinometer, this article contrastively applies traditional curve fitting method and artificial neural network theory in the error correction work of inclinometer. Besides, this article also establishes the coordinate transformation model and gives details about the ...
