یکی از موارد مهم در طراحی راکتور های هسته ای، لحاظ کردن فاکتور های ایمنی در آنها می باشد. از جمله مهمترین این فاکتورها، کنترل توان راکتور و خاموش سازی آن در هنگام وقوع حادثه است که میله های کنترل نقش بسیار موثری در این زمینه دارند. باتوجه به پیشرفت روز به روز کدها ی هسته ای، استفاده از کد mcnp به عنوان یک کد پیشرفته باعث هر چه واقعی تر شدن نتایج حاصل از شیبه سازی می شود. در این تحقیق اطلاعات لا...
In this paper, we give a characterization of strongly Jordan zero-product preserving maps on normed algebras as a generalization of Jordan zero-product preserving maps. In this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly Jordan zero-product preserving maps are completely different. Also, we prove that the direct p...
Applications in which data take nonnegative values but have a substantial proportion of values at zero occur in many disciplines. The modeling of such “clumped-at-zero” or “zero-inflated” data is challenging. We survey models that have been proposed. We consider cases in which the response for the non-zero observations is continuous and in which it is discrete. For the continuous and then the d...
Let $R$ be an associative ring with identity and $Z^*(R)$ be its set of non-zero zero divisors. The zero-divisor graph of $R$, denoted by $Gamma(R)$, is the graph whose vertices are the non-zero zero-divisors of $R$, and two distinct vertices $r$ and $s$ are adjacent if and only if $rs=0$ or $sr=0$. In this paper, we bring some results about undirected zero-divisor graph of a monoid ring o...
Smart homes with zero energy as an option to combine a large number of distributed energy resources to power networks in building a new future designs, are used. Zero energy homes equipped with smart power integrated production and consumption of zero over a year. In this study is that the sources of energy supply management program for a zero-energy home using mixed integer programming techniq...
