  • The spectrum of the hyper-star graphs and their line graphs 

    Karimi, F.؛ Mirafzal, S. M. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-12-01)
    Let n 1 be an integer. The hypercube Qn is the graph whose vertex set isf0;1gn, where two n-tuples are adjacent if they differ in precisely one coordinate. This graph has many applications in Computer sciences and ...

  • Solution of Backup Multifacility Location Problem by Considering the Ideal Radius for each Customer 

    fathali, jafar؛ nazari, morteza (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-12-01)
    In this paper we introduce a new facility location model, called backup multifacility location problem by considering the ideal radius for each customer. In this problem the location of clients are given in the plane. A ...

  • Evaluation of Model-Based Methods in Estimating Dynamic Functional Connectivity of Brain Regions 

    Behboudi, M.؛ Farnoosh, R.؛ Oghabian, M. A.؛ Pezeshk, H. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-12-01)
    Today, neuroscientists are interested in discovering human brain functions through brain networks. In this regard, the evaluation of dynamic changes in functional connectivity of the brain regions by using functional ...

  • Euler-Lagrange equations and geometric mechanics on Lie groups with potential 

    Suri, Ali (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-12-01)
    Abstract. Let G be a Banach Lie group modeled on the Banach space, possibly infinite dimensional, E. In this paper first we introduce Euler-Lagrange equations on the Lie group G with potential and right invariant metric. ...

  • Mathematical Model and Algorithm for sequencing operations in the machine building industry 

    fallah, M.؛ ghorani, N. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-12-01)
    In this paper, the problem of sequencing machines in the final assembly line with regard to the supply of parts has been investigated. For this reason, a basic integer linear programming model has been developed and based ...

  • On the Maximum Number of Dominating Classes in Graph Coloring 

    Faghani, M. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-12-01)
    In this paper we investigate the dominating- -color number،  of a graph G. That is the maximum number of color classes that are also dominating when G is colored using colors. We show that where is the ...

    One of the most important concerns of investors in financial markets is choosing a share or stock portfolio that is optimal in terms of profitability. To this end, there are many ways in which the stock portfolio has been ...

  • 𝛅- homomorphism maps into dual Banach algebras 

    Hayati, B.؛ Khodaei, H. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-12-01)
    Let A be a Banach algebra and (B,B_*) be a dual Banach algebra. A linear map φ:A⟶B is said to be a δ - homomorphism map if ‖‖φ(a_1 a_2)-φ(a_1)φ(a_2)‖‖≤δ‖‖a_1‖‖ ‖‖a_2 ‖‖ for every a_1,a_2∈A. In this paper, we study ...
