This paper proposes an improved score function for the effective ranking order of interval-valued intuitionistic fuzzy sets (IVIFSs) and an interval-valued intuitionistic fuzzy TOPSIS method based on the score function to solve multicriteria decision-making problems in which all the preference information provided by decision-makers is expressed as interval-valued intuitionistic fuzzy decision ...

In some schools and universities, students from the same grade must sometimes be divided into several teams within a classroom in such a way that each team provides a good representation of the classroom population. Therefore a first problem to solve is to choose student attributes (criteria) to include into the process of designing the teams and to determine their relative importance for the s...

Closeness centrality is an important concept in social network analysis. In a graph representing a social network, closeness centrality measures how close a vertex is to all other vertices in the graph. In this paper, we combine existing methods on calculating exact values and approximate values of closeness centrality and present new algorithms to rank the top-k vertices with the highest close...

conclusions the findings suggest that the development of preventive programs will contribute to increases in the child-mother closeness relationship and will help to prevent the onset of substance use in children. background considering the fundamental role that parents play in a family dynamic, it is important to explore the parent-child relationship and examine what protective behaviors or ri...

Background: To study if patients that have a second radiograph 2 or more years after nonoperative treatment of an isolated radial head fracture have radiocapitellar osteoarthritis (RC OA). Methods: We used the database of 3 academic hospitals in one health system from 1988 to 2013 to find patients with isolated radial head fractures (no associated ligament injury or fracture) that had a second ...

making an informed decision with regards to a suitable business location or site selection for organizations is becoming challenging for business decision makers globally; and even more challenging in business environment that are saddled with uncertainties. the continues raise of multiple criteria variation of site preferences has also necessitated the application of advanced decision making t...

The availability of advanced social interaction sensing technologies provides fine grained data for social network analysis. Although traditional methods of gathering social network data may be subject to human ability to recall social details, people’s rating of their closeness to persons in their network is important. This study assesses the relationship amidst closeness ratings, sensed inter...

in an experiment, chemical composition, phenolics and fermentation parameters of different parts of raisin co-products (rc) were determined using in vitro gas production with or without polyethylene glycol (peg). different parts of rc included rejected raisins, pedicle, rachis, mixture of raisins, pedicle and rachis, and shekarak (a powder product obtained following sorting of raisins for packi...

The goal of this work is to identify the nodes that have the smallest sum of distances to other nodes (the lowest closeness centrality nodes) in graphs that evolve over time. Previous approaches to this problem find the lowest centrality nodes efficiently at the expense of exactness. The main motivation of this paper is to answer, in the affirmative, the question, ‘Is it possible to improve the...
