let $x$ be a sufficiently nice scheme. we survey some recent progress on dualizing complexes. it turns out that a complex in $kinj x$ is dualizing if and only if tensor product with it induces an equivalence of categories from murfet's new category $kmpr x$ to the category $kinj x$. in these terms, it becomes interesting to wonder how to glue such equivalences.

The concept of complex fuzzy sets is a generalization of ordinary fuzzy sets. In this paper, we introduce the concept of complex fuzzy subhypergroups ($H_{v}$-subgroups) as well as the concept of complex anti-fuzzy subhypergroups ($H_{v}$-subgroups). We investigate their properties and their relations with the traditional fuzzy (anti-fuzzy) subhypergroups ($H_{v}$-subgroups), and we prove some ...

کاربرد موفقیت آمیز مدل های بارش – رواناب، به چگونگی واسنجی پارامترهای آنها بستگی دارد. مدل های مفهومی بارش - رواناب، عموماً دارای پارامترهای زیادی هستند که نمی توان آنها را به صورت مستقیم برآورد نمود و لازم است که آنها را در طول واسنجی مدل تخمین زد. هدف از انجام واسنجی، یافتن مقادیر آن سری از پارامترهایی است که باعث بهینه شدن معیارهای ارزیابی کارایی مدل می شوند. دو روش دستی و خودکار برای واسنجی ...
