  • A Mathematical Model for Evaluating the Efficiency of the University of Kashan’s Faculties 

    Davtalab-Olyaie, Mostafa؛ Maleki, Saeed (University of Kashan, 2020-03-01)
    Efficiency evaluation of units has been of interest since many years in different domains such as management, economy, business, banking, and many others. Data envelopment analysis is one of the popular operations research ...

  • Random walk modeling for retrieving information on semantic networking 

    Abarghouei Nejad, Meghdad؛ Abarghouei Nejad, Meghdad؛ Hatami, Javad؛ Asadpour, Masoud (University of Kashan, 2020-03-01)
    In this article, the famous random walk model is exploited as a model of stochastic processes to retrieve some specific words which are used in social media by users. By spreading activation on semantic networking, this ...

  • Structure of the Fixed Point of Condensing Set-Valued Maps 

    Soltani, Z. (University of Kashan, 2020-03-01)
    In this paper, we present structure of the fixed point set results for condensing set-valued map. Also, we prove a generalization of the Krasnosel'skii-Perov connectedness principle to the case of condensing set-valued maps.

  • On the Estrada index of Seidel Matrix 

    Hakimi-Nezhaad, Mardjan؛ Ghorbani, Modjtaba (University of Kashan, 2020-03-01)
    Let G be a simple graph with n vertices and with the Seidel matrix S‎. ‎Suppose μ1‎, ‎μ2,..., μn are the Seidel eigenvalues of G‎. ‎The Estrada index of the Seidel matrix of G is defined as SEE(G)=‎sum_{i=1}^{n} eμi‎. ‎In ...

  • Some Graph Polynomials of the Power Graph and its Supergraphs 

    Hamzeh, Asma (University of Kashan, 2020-03-01)
    ‎In this paper‎, ‎exact formulas for the dependence‎, ‎independence‎, ‎vertex cover and clique polynomials of the power graph and its‎ ‎supergraphs for certain finite groups are presented‎.

  • Zagreb Indices and Coindices of Total Graph, Semi-Total Point Graph and Semi-Total Line Graph of Subdivision Graphs 

    Ramane, Harishchandra؛ Talwar, Saroya؛ Gutman, Ivan (University of Kashan, 2020-03-01)
    Expressions for the Zagreb indices and coindices of the total graph, semi-total point graph and of semi-total line graph of subdivision graphs in terms of the parameters of the parent graph are obtained, thus generalizing ...
