In this paper I present and defend a definition of vagueness, and draw out some consequences of accepting this definition. §1 asks what we should properly expect of a definition of vagueness, and §2 reviews existing definitions. §3 explains a key background notion necessary to an understanding of the definition to be presented here. §4 presents this definition, and §5 explains its advantages. §...

Abstract In this paper, complex network analysis is used to analyze the structure of a whole river basin. A classification nodes and edges that allow basin be represented as directed given. Both global local characterization metrics are presented. Thus, centralization indexes, average path length, diameter, efficiency, edge degree strength distributions can computed interpreted. The closeness b...

In two studies, college students’ achievement goals were linked to their perceptions of closeness to their parents following an exam. In Study 1, mastery-approach goals positively predicted perceived closeness immediately after an exam, prior to receiving feedback. In Study 2, mastery-approach goals again positively predicted perceived closeness, but performance–avoidance goals interacted with ...

Identifying influential nodes in complex networks has received increasing attention for its great theoretical and practical applications in many fields. Some classical methods, such as degree centrality, betweenness centrality, closeness centrality, and coreness centrality, were reported to have some limitations in detecting influential nodes. Recently, the famous h-index was introduced to the ...

We consider variations of two well-known centrality measures, betweenness and closeness, with a different model of information spread. Rather than along shortest paths only, it is assumed that information spreads efficiently like an electrical current. We prove that the current-flow variant of closeness centrality is identical with another known measure, information centrality, and give improve...

Identifying the node spreading influence in networks is an important task to optimally use the network structure and ensure the more efficient spreading in information. In this paper, by taking into account the shortest distance between a target node and the node set with the highest k-core value, we present an improved method to generate the ranking list to evaluate the node spreading influenc...

or as the ends of a boiv are drawn together." They have a legend that it visits the country every thirty years. The epidemic arrived in Bhamo in June last, having travelled up the Irrawaddy Yalley starting in Rangoon in May and visiting Mandalay during the early part of June. It is interesting to note this following of the important trade route. It is not unlikely that the epidemic originated f...

This research proposes a vigorous methodology based on the fuzzy set theory to improve the facility layout process. Using natural language, the fuzzy set theory is an appropriate tool for controlling complex systems such as facility planning. The closeness rating between departments in a plant depends on qualitative and quantitative factors. Some of these factors may have a greater effect on th...
