An extension method for t-norms on subintervals to t-norms on bounded lattices
(Kybernetika, 2019)In this paper, a construction method on a bounded lattice obtained from a given t-norm on a subinterval of the bounded lattice is presented. the supremum distributivity of the constructed t-norm by the mentioned method is ... -
Global stability in a pathogen-specific cd8 immune response prediction model
(Yildiz Technical Univ, 2019)In this study, a system of ordinary differential equations used for modeling pathogen-specific CD8 cell immune response is studied. the positivity and the limitation of the model solutions are proven. the equilibrium points ... -
Inventory model of type (s, S) under heavy tailed demand with infinite variance
(Brazilian Statistical Association, 2019)In this study, a stochastic process X(t), which describes an inventory model of type (s, S) is considered in the presence of heavy tailed demands with infinite variance. the aim of this study is observing the impact of ... -
t-closure operators
(Taylor & Francis Ltd, 2019)In this study, based on the knowledge of the existence of t-norms on an arbitrary given bounded lattice, we introduce t-closure operators with the help of a t-norm on the lattice and a subset of the lattice including the ... -
De Moivre's and Euler's formulas for the matrices of octonions
(Natl Acad Sciences India, 2019)The purpose of this paper is to obtain de Moivre's and Euler's formulas for the matrices of octonions, and to find the powers and the roots of these matrices. A simple method is provided to find the powers of 8x8 matrices ... -
Some new construction methods for t-norms on bounded lattices
(Taylor & Francis Ltd, 2019)In this paper, three methods for constructing triangular norms on a bounded lattice L from t-norm W on sub-lattice of L are investigated. An example is added to reveal the difference of three construction methods. the ... -
Evaluation of the convolution sum sigma(al+bm=n) sigma(l)sigma(m) for (a, b) = (1, 48), (3, 16), (1, 54), (2, 27)
(Wydawnictwo Naukowe Uam, 2019)We determine the convolution sum Sigma(al+bm=n) sigma(l)sigma(m) for (a, b) = (1, 48), (3, 16), (1, 54), (2, 27) for all positive integers n. We then use these evaluations together with known evaluations of other convolution ... -
Split-type octonion matrix
(Wiley, 2019)The split and hyperbolic (countercomplex) octonions are eight-dimensional nonassociative algebras over the real numbers, which are in the form X = x(0)e(0) + Sigma(7)(j=1)x(j)e(j) e(m)'s (0 <= m <= 7) have different ... -
On orders induced by implications
(Univ Sistan & Baluchestan, 2019)In this paper, the orders induced by the residual implications obtained from uninorms are investigated. A necessary and sufficient condition is presented so that the ordinal sum of fuzzy implications satisfies the law of ... -
A simplified neutrosophic multiplicative set-based TODIM using water-filling algorithm for the determination of weights
(Wiley, 2020)Due to the technological developments around the world, the amount of information that researchers work on increases continuously. This information density contains incomplete and uncertain data that cannot be fully expressed ... -
Serret-frenet formulas for octonionic curves
(Soc Paranaense Matematica, 2020)In this paper, we define spatial octonionic curves (SOC) in R( )(7)and octonionic curves (OC) in R-8 by using octonions. Firstly, we determine Serret-Frenet equations, and curvatures of the SOC in R-7. Then, Serret-Frenet ... -
On the relationships between the orders induced by uninorms and nullnorms
(Elsevier, 2020)In this paper, some relationships between the orders induced by uninorms and nullnorms are discussed. Some relations between the sets admitting some incomparability w.r.t. those orders are investigated. Also, some relationships ... -
Ordering based on uni-nullnorms
(Ios Press, 2020)In this paper, orders based on uni-nullnorms on bounded lattices are introduced and discussed. By this way, the existing orders in the literature induced by t-norms, t-conorms, uninorms and nullnorms are extended to much ... -
Modification of the random differential transformation method and its applications to compartmental models
(Taylor & Francis Inc, 2020)In this study, a modification of the random differential transformation method is given by using Laplace-Pade method. the modification, which has previously been introduced for the deterministic differential transformation ... -
On suborbital graphs for the group gamma(3)
(Springer Singapore Pte Ltd, 2020)In this paper, we investigate suborbital graphs generated by the action of the group G 3 which is the group obtained from the third powers of the elements of the modular group G on Q. {8}. First, we give necessary and ... -
Generalized convex combination of triangular norms on bounded lattices
(Taylor & Francis Ltd, 2020)In this paper, we introduce the notions of the linear and generalized convex combination (shortly, g-convex combination) for triangular norms on bounded lattices. We investigate the conditions for the g-convex combination ... -
Generalized convex combination of implications on bounded lattices
