This paper is a contribution to the formalisation of Thagard's coherence theory. The term 'coherence' is defined as the quality or the state of cohering, especially a logical, orderly, and aesthetically consistent relationship of parts. A coherent set is interdependent such that every element in it contributes to the coherence. We take Thagard's proposal of a coherence set as that of maximising...

in this article, the results of special effects of privatization of iranian gas refining industry with delphi-dematel integrative approach are presented. according to the results of this research in delphi technique base, all together, experts recognize 39 pivotal factors in privatization of the gas refining companies. then by the aids of dematel technique, in previous step, according to expert...

Unsupervised cross-modal hashing (UCMH) has become a hot topic recently. Current UCMH focuses on exploring data similarities. However, current methods calculate the similarity between two data, mainly relying data's features. These suffer from inaccurate problems that result in suboptimal retrieval Hamming space, because features are not sufficient to describe complex relationships, such as sit...

This paper presents a new characterization of graph transformation rules for simple digraphs based on boolean matrix algebra. We introduce the concept of coherence, which allows the analysis of potential incompatibilities among rules that take part in a sequence of productions. Concurrency is studied under the interleaving and the explicit parallelism views. For the former, the notion of sequen...

Let $G$ be a connected graph, and let $D[G]$ denote the double graph of $G$. In this paper, we first derive closed-form formulas for different distance based topological indices for $D[G]$ in terms of that of $G$. Finally, as illustration examples, for several special kind of graphs, such as, the complete graph, the path, the cycle, etc., the explicit formulas for some distance based topologica...

Background: Graph theory has been recently introduced to characterize complex brain networks, making it highly suitable to investigate altered connectivity in neurologic disorders. A current model proposes autism spectrum disorder (ASD) as a developmental disconnection syndrome, supported by converging evidence in both non-syndromic and syndromic ASD. However, the effects of abnormal connectivi...
