the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Optimal variable shape parameter for multiquadric based RBF-FD method

In this follow up paper to our previous study in [2], we present a new technique to compute the solution of PDEs with the multiquadric based RBF finite difference method (RBF-FD) using an optimal node dependent variable value of the shape parameter. This optimal value is chosen so that, to leading order, the local approximation error of the RBF-FD formulas is zero. In our previous paper [2] we ...

تععین پارامتر های ترانسفورماتور به منظور تشخیص خطا transformer parameter determination for the purpose of failure diagnosis

چکیده ترانسفورماتورهای قدرت ادوات گران قیمتی هستنند که نقش بسیار مهمی را در سیستم های قدرت ایفا می کنند. در سالهای اخیر روشهای مختلفی جهت تشخیص خطا و مونیتورینگ ترانسفورماتورها ارائه شده است. در این پایان نامه برخی از این روشها جهت تعیین پارامتر های ترانسفورماتور در شرایط سالم و خطاهای مختلف در محدوده ی وسیعی از فرکانس بررسی شده است. همچنین با استفاده از روش اجزای محدود و محاسبات بر پایه فرمو...
