We focus on the innovation “problem” as the central unit of analysis, arguing for a match between problem types and governance forms, which vary from open to closed and which support alternative forms of solution search. In all, the goal of this paper is to provide a comparative framework...
(r,s)-Fuzzy F-open sets and (r,s)-fuzzy F-closed spaces In this paper, we introduce the concepts of (r,s)-fuzzy F-open and (r,s)-fuzzy F-closed sets in double fuzzy topological spaces. We used them to explain th... MA Abd-Allah,K El-Saady,A Ghareeb - 《Chaos Solitons &...
The conclusion is the closed-ended questions provide metrics which generally track the results found in the open-ended questions and there are no apparent gaps between the two sets of information 展开 年份: 2015 收藏 引用 批量引用 报错 分享 ...

In this paper, we introduce and study new classes of pre-open and pre-closed sets calledΠ--pre-open and Π-preclosed, which are the generalizations of bothΠ--open and Π-closed. We present and prove some basic properties of them. We prove that an open subspace of a sub-maximal spac...
Moreover, we show that soft 𝑅𝜔-open subsets of a soft anti-locally countable coincide with the soft regular open sets. Moreover, we show that the class of soft 𝑅𝜔-open sets is closed under finite soft intersection, and as a conclusion, we show that this class forms a soft ...

1. This scheme achieved the open-set identification of wood species and leaves. Currently, wood species recognition is mostly performed in closed sets. It is exciting to be able to achieve an efficient open-set identification without compromising wood species. 2. In this scheme, an open-set re...
