تعیین مکان و اندازه بهینه منابع تولید پراکنده (dgs) در سیستم های توزیع برای کسب ماکزیمم منافع بالقوه با اهمیت می باشد. در این پایان نامه یک طراحی چند هدفه برای تعیین مکان و اندازه منابع dg در شبکه های توزیع موجود مبتنی بر روش ipso-monte carlo ارائه شده است. اهداف شامل مینیمم کردن تلفات اکتیو و راکتیو، بهبود پروفایل ولتاژ و بهبود قابلیت اطمینان سیستم های توزیع می باشد. تکنیک بکار رفته مبتنی بر ا...

In this paper we propose a new and original approach to solve the Inverse Kinematics problem. Our approach has the advantages to avoid the classical pitfalls of numerical inversion methods such as singularities, accept arbitrary types of constraints and exhibit a linear complexity with respect to degrees of freedom which makes it far more efficient for articulated figures with a high number of ...

The problem of evaluating the dominant eigenvalue of real matrices using Monte Carlo numerical methods is considered. Three almost optimal Monte Carlo algorithms are presented: – Direct Monte Carlo algorithm (DMC) for calculating the largest eigenvalue of a matrix A. The algorithm uses iterations with the given matrix. – Resolvent Monte Carlo algorithm (RMC) for calculating the smallest or the ...

introduction: the main goal of spect imaging is to determine activity distribution inside the organs of the body. however, due to photon attenuation, it is almost impossible to do a quantitative study. in this paper, we suggest a mathematical relationship between activity distribution and its corresponding projections using a transfer matrix. monte carlo simulation was used to find a precise tr...
