islanding detection methods for microgrids
امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولA New Approach for Heterogeneity Corrections for Cs-137 Brachytherapy Sources
Background: Most of the current brachytherapy treatment planning systems (TPS) use the TG-43U1 recommendations for dosimetry in water phantom, not considering the heterogeneity effects.Objective: The purpose of this study is developing a method for obtaining correction factors for heterogeneity for Cs-137 brachytherapy sources based on pre-calculated MC simulations and interpolation.Method: To ...

alcoholism posits that biological, psychological, and social factors jointly contribute to the development of alcoholism and alcoholrelated problems. Although researchers have made significant progress in elucidating the biological and psychological elements of alcohol use and its associated problems, the analysis of the social component has substantially lagged behind. One approach to facilita...
متن کاملDynamical many-body corrections to the residual resistivity of metals
The residual resistivity of metals at the absolute zero of temperature is usually understood in terms of electrons scattering from random impurities. This mechanism, however, does not take into account dynamical many-body effects, which cannot be described in terms of a static electron-impurity potential. Here we show that dynamical corrections to the resistivity, already known to play a role i...
متن کاملSimulation of 3D DC Borehole Resistivity Measurements with a Goal- Oriented hp Finite-Element Method. Part I: Laterolog and LWD
We simulate and study the combined three-dimensional effects on resistivity logging measurements due to dip angle (in deviated wells), different arrangements of three-dimensional electrodes, and anisotropy effects. All results correspond to electrostatic (zero frequency) measurements. Thus, we consider direct current (DC) electrodes. We simulate both laterolog and logging-while-drilling (LWD) m...
