  • Completeness in Probabilistic Metric Spaces 

    Varasteh Tafti, D.؛ Azhini, M. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    The idea of probabilistic metric space was introduced by Menger and he showed that probabilistic metric spaces are generalizations of metric spaces. Thus, in this paper, we prove some of the important features and theorems ...

  • Coupled fixed point on ordered cone metric spaces with application in integral equations 

    Ghods, S.؛ Eshaghi Gordji, M. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    Our theorems are on ordered cone metric spaces which are not necessarily normal. In the end, we describe the application of the main results in the integral equation.Although Du in [W‎. ‎S‎. ...

  • Edge 2-rainbow domination number and annihilation number in trees 

    Dehgardi, N. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    A edge 2-rainbow dominating function (E2RDF) of a graph G is a ‎function f from the edge set E(G) to the set of all subsets‎ ‎of the set {1,2} such that for any edge.......................

  • Function Approximation Approach for Robust Adaptive Control of Flexible joint Robots 

    Izadbakhsh, A. R.؛ Bodaghi, A. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    This paper is concerned with the problem of designing a robust adaptive controller for flexible joint robots (FJR). Under the assumption of weak joint elasticity, FJR is firstly modeled and converted into singular perturbation ...

  • MULTIPLIERS AND THEIR APPLICATIONS IN EARTHQUAKE ENGINEERING 

    Adib, M. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    In this paper we shall study the multipliers on Banach algebras and We prove some results concerning Arens regularity and amenability of the Banach algebra M(A) of all multipliers on a given Banach algebra ...

  • Numerical Solution of fuzzy differential equations of nth-order by Adams-Bashforth method 

    Parandin, N. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    So far, many methods have been presented to solve the rst-order di erential equations. But, not many studies have been conducted for numerical solution of high-order fuzzy di erential equations. In this research, First, ...

  • Performance analysis in production processes in the presence of fixed-sum outputs 

    Amirteimoori, A. R.؛ Masroori, S.؛ Kordrostami, S. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    Performance measurement in the presence of fixed-sum outputs in data envelopment analysis (DEA) is an interesting and most frequently studied subject in the field of operations research. Different definitions of relative ...

  • Performance Measurement of Decision Making Units with Network Structure in the Presence of Undesirable Output 

    Peykani, P.؛ Mohammadi, E. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    In the performance evaluation process, using the classic data envelopment analysis (DEA) models, decision making units (DMUs) are considered as black boxes. While in many cases and different applications such as ...

  • The use of radial basis functions by variable shape parameter for solving partial differential equations 

    Nojavan, H.؛ Abbasbandy, S.؛ Allahviranloo, T. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    In this paper, some meshless methods based on the local Newton basis functions are used to solve some time dependent partial differential equations. For stability reasons, used variably scaled radial kernels for constructing ...

  • Using Data Mining and Three Decision Tree Algorithms to Optimize the Repair and Maintenance Process 

    Izadikhah, M.؛ Garshasbi, D. (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    The purpose of this research is to predict the failure of devices using a data mining tool. For this purpose, at the outset, an appropriate database consists of 392 records of ongoing failures in a pharmaceutical company ...

  • A Value Efficiency-Based Target Setting Approach in Data Envelopment Analysis 

    Nasrabadi, Nasim (Science and Research Branch, Islamic Azad Universityدانشگاه آزاد اسلامی واحد علوم و تحقیقات, 2019-04-01)
    Basic models of Data Envelopment Analysis are intrinsically preference-free, in the sense that they consider all inputs and outputs and also all decision making units of the same importance. Although this property is ...
