  • Monadic algebras of an involutive monoidal t-norm based logic 

    Wang, J. T.؛ Xin, X. L. (University of Sistan and Baluchestan, 2022-06-01)
    The main goal of this paper is to study universal and existential quantifiers on involutive monoidal t-norm based algebras, which are algebraic semantics for the logic of involutive left-continuous t-norms and their residua, ...

  • Ordinal fuzzy entropy 

    He, Y.؛ Deng, Y. (University of Sistan and Baluchestan, 2022-06-01)
    In real life, occurrences of a series of things are supposed to come in an order. Therefore, it is necessary to regard sequence as a crucial factor in managing different kinds of things in fuzzy environment. However, few ...

  • Improved q-rung orthopair and T-spherical fuzzy sets 

    Riyahi, M.؛ Borumand Saeid, A.؛ Kuchaki Rafsanjani, M. (University of Sistan and Baluchestan, 2022-06-01)
    Different extensions of fuzzy sets like intuitionistic, picture, Pythagorean, and spherical have been proposed to model uncertainty. Although these extensions are able to increase the level of accuracy, imposing rigid ...

  • Neighborhood connectivity index of a fuzzy graph and its application to human trafficking 

    Josy, A.؛ Mathew, S.؛ Mordeson, J. N. (University of Sistan and Baluchestan, 2022-06-01)
    Connectivity is an inevitable part of fuzzy graph theory. This article discusses about a parameter in  fuzzy graph theory termed as   neighborhood connectivity index. Several bounds and index values of structures like ...

  • Maximal product of two L-graph automata and some applications 

    Raisi Sarbizhan, E.؛ Zahedi, M. M. (University of Sistan and Baluchestan, 2022-06-01)
    The current study aimed to describe the notion of the L-graph, which is constructed on a residuated lattice, presenting the idea of the maximal product of two L-graphs.    Moreover, the applied algorithm demonstrated its ...

  • Novel distance measure between intuitionistic fuzzy sets and its application in pattern recognition 

    Zeng, W. Y.؛ Cui, H. S.؛ Liu, Y. Q.؛ Yin, Q.؛ Xu, Z. S. (University of Sistan and Baluchestan, 2022-06-01)
    In this article, we propose a new distance measure between intuitionistic fuzzy sets(IFSs), which takes into account the membership degree, non-membership degree, and their difference between membership and non-membership ...

  • (L,M)-fuzzy topological derived internal relations and (L,M)-fuzzy topological derived enclosed relations 

    Wu, X. Y.؛ Shi, Y. (University of Sistan and Baluchestan, 2022-06-01)
    In this paper, notions of \LM fuzzy topological derived internal relation space and \LMfuzzy topological derived interior space are introduced.It is proved that they are categorically isomorphic to \LM fuzzy topological ...

  • Compactness of first-order fuzzy logics 

    Khatami, S. M. A. (University of Sistan and Baluchestan, 2022-06-01)
    One of the nice properties of the first-order logic is the compactness of satisfiability. It states that a finitely satisfiable theory is satisfiable. However, different degrees of satisfiability in fuzzy logics will pose ...

  • A novel Kumaraswamy interval type-2 TSK fuzzy logic system for subway passenger demand prediction 

    Saghian, Z.؛ Esfahanipour, A.؛ Karimi, B. (University of Sistan and Baluchestan, 2022-06-01)
    Fuzzy logic systems (FLSs) are proper tools for learning and predicting of real-world problems. Type-2 fuzzy sets are developments of the conventional type-1 fuzzy sets which are applied for prediction problems with ...

  • Aggregation of fuzzy metrics and its application in image segmentation 

    Ralevic, N. M.؛ Delic, M.؛ Nedovic, Lj. (University of Sistan and Baluchestan, 2022-06-01)
    This paper proposes a novel method for the construction of a fuzzy metrics and demonstrates application in image segmentation. Some new properties of t-norms, t-conorms, aggregation functions, and fuzzy metrics are proved, ...

  • Statistical testing quality and its Monte Carlo simulation based on fuzzy specification limits 

    Iranmanesh, H.؛ Parchami, A.؛ Sadeghpour Gildeh, B. (University of Sistan and Baluchestan, 2022-06-01)
    This paper presents two approaches for testing quality to make adecision based on the extended process capability indices. Common methodsin measuring quality of the manufactured product have widely focused on theprecise ...

  • Fuzzy betweenness spaces on continuous lattices 

    Zhang, S. Y.؛ Shi, F. G. (University of Sistan and Baluchestan, 2022-06-01)
    The notion of betweenness spaces is very important in  convex structure theory. In this paper,  it is generalized to continuous lattices. Then  its some characterizations and properties are investigated.Finally  the ...

  • A new stability criterion for high-order dynamic fuzzy systems 

    Zeighami, Z.؛ Jahed-Motlagh, M. R.؛ Moarefianpour, A.؛ Heydari, G. (University of Sistan and Baluchestan, 2022-04-01)
    Fuzzy modeling is a well-known solution for simplified modeling and predicting nonlinear systems behavior. Dynamic TSK Fuzzy Systems are an important branch in fuzzy modeling and are used for complex nonlinear dynamic ...

  • On the distributivity of T-power based implications 

    Peng, Z.؛ Pan, J. (University of Sistan and Baluchestan, 2022-04-01)
    Due to the fact that Zadeh's quantifiers constitute the usual method to modify fuzzy propositions, the so-called family of T-power based implications was proposed. In this paper,  the four basic distributive laws  related ...
