کنترل توان منابع تولید پراکنده با قابلیت plug and play
در دو دهه گذشته، مسائلی مانند گرمایش زمین و آلودگی هوا و از طرف دیگر افزایش تقاضا برای انرژی برق، دست اندرکاران و تصمیم گیرندگان صنعت برق را براین داشته که به سوی تولید انرژی برق از منابع انرژی تجدید پذیر مانند انرژی خورشیدی، بادی و همچنین تکنولوژی های جدیدتر مانند پیل های سوختی گام بردارند. در این پایان نامه کنترل توان منابع تولید پراکنده مورد بررسی قرار گرفته است. کنترل توان پیل سوختی متصل به...
Inflation and Eternal Inflation
The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in te...
متن کاملEternal inflation and its implications ‡
I summarize the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in terms of the way that predictions are extracted from theore...
متن کاملEternal domination: criticality and reachability
We show that for every minimum eternal dominating set, D, of a graph G and every vertex v ∈ D, there is a sequence of attacks at the vertices of G which can be defended in such a way that an eternal dominating set not containing v is reached. The study of the stronger assertion that such a set can be reached after a single attack is defended leads to the study of graphs which are critical in th...
متن کاملEternal inflation and chaotic terminology
“Eternal inflation” is often confused with “chaotic inflation”. Moreover, the term “chaotic inflation” is being used in three different meanings (all of them unrelated to eternal inflation). I make some suggestions in an effort to untangle this terminological mess. I also give a brief review of the origins of
