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 ...

RALL: Machine-Supported Proofs for Relation Algebra

We present a theorem proving system for abstract relation algebra called RALL Relation Algebraic Language and Logic based on the generic theorem prover Isabelle On the one hand the system is an advanced case study for Isabelle HOL and on the other hand a quite mature proof assistant for research on the relational calculus RALL is able to deal with the full language of heterogeneous relation alg...

Huff Selected for APHA's Rall Award

Production of specific immunoglobulin (Ig)E is the characteristic abnormality of atopy. IgE is produced by B lymphocytes under the influence of interleukin (IL)4 and IL-13. IgE binds to high-affinity IgE receptors (Fc«RI) on mast cells to induce degranulation and mediator synthesis. IL-4 enhances the activation of Fc«RI to augment the production of cytokines and lipid mediators. These receptors...

Few guidelines for analyzing methods

All these dimensions are not necessarily simultaneously present. For instance, if we are dealing with a simple problem for which an exact polynomial algorithm is known, the problem instance space is often restricted to the positive integers, corresponding to the instance size. Indeed, in this case, we are mainly interested by the evolution of the computational effort with the problem size growt...
