Recently we used the onion peeling method to reconstruct the axisymmetric electric field distribution of point/plane electrodes from Kerr electro-optic measurements. The method accurately reconstructed the electric field from numerically generated data. However in the presence of experimental noise the performance was less satisfactory. The measurements were especially noisy and unstable near t...

The present work mainly studies the free vibration of circular magneto-electro-elastic (MEE) nano-plates based on the Kirchhoff’s plate theory within the framework of nonlocal elasticity theory to account for the small scale effect. The MEE nano-plate studied here is considered to be fully clamped and subjected to the external magnetic and electric potentials. Using nonlocal constitutive relati...

در ابتدا به طور مختصر ارتباط بین مسائل تغییراتی و معادلات دیفرانسیل را بیان می کنیم. همان طور که می دانیم هر معادله دیفرانسیل را می توان به صورت ‎egin{equation} label{yek}‎ ‎a(u)= 0‎ ‎end{equation}‎ نوشت، که در آن ‎$ a(u) $‎ یک عملگر دیفرانسیل معمولی یا جزئی خطی یا غیرخطی و ‎$ u $‎ مجهول می باشد. برای حل این معادلات و به خصوص معادلات دیفرانسیل جزیی غیرخطی راه حل مشخصی وجود ندارد.حساب تغییر...

A design synthesis technique based on sensitivity for Micro-Electro-Mechanical Systems (MEMS) proposed. This new technique can be called Sensitivity-Based Direct Solution Algorithm (DSA) of design synthesis for MEMS with expected performance. Design synthesis with expected performance is regarded as a reverse problem of MEMS analysis. Behavior equation group can be educed from analysis equation...

it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...

The mesocrystal showing both electrorheological and magnetorheological effects is called electro-magnetorheological (EMR) solids. Prediction of the overall magnetic properties of the EMR solids is a challenging task due to the coexistence of the uniaxially anisotropic behavior and structural transition as well as long-range interaction between the suspended particles. To consider the uniaxial a...
