Global dynamics of a cooperative discrete system in the plane
(World Scientific Publ Co Pte Ltd, 2018)In this paper, we consider the cooperative system x(n+1) = ax(n) + by(n)(2)/1 + y(n)(2), y(n+1) = cx(n)(2)/1 + x(n)(2) + dy(n), n = 0, 1, ... , where all parameters a, b, c, d are positive numbers and the initial conditions ... -
Normal curves in n-dimensional Euclidean space
(Springeropen, 2018)In this paper, we give a generalization of normal curves to n-dimensional Euclidean space. Then we obtain a necessary and sufficient condition for a curve to be a normal curve in the n-dimensional Euclidean space. We ... -
Modelling of cohesive -sediment depositional areas carried by the Solakh River to the Eastern Black-Sea
(Natl Inst Science Communication-Niscair, 2018)In this study, cohesive sediment depositional areas carried by the Solakh River to the Eastern Black-Sea are examined in the marine environment. Effects of changes in the amount of cohesive sediment entering the sea from ... -
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 ... -

(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 ... -
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 ... -
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 ... -
Construction methods for implications on bounded lattices
(Kybernetika, 2019)In this paper, the ordinal sum construction methods of implications on bounded lattices are studied. Necessary and sufficient conditions of an ordinal sum for obtaining an implication are presented. New ordinal sum ... -
Construction methods for uni-nullnorms and null-uninorms on bounded lattice
(Kybernetika, 2019)In this paper, two construction methods have been proposed for uni-nullnorms on any bounded lattices. the difference between these two construction methods and the difference from the existing construction methods have ... -
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 ... -
Matrix transformations and compact operators on the binomial sequence spaces
(Kangwon-Kyungki Mathematical Soc, 2019)In this work, we characterize some matrix classes concerning the Binomial sequence spaces b(infinity)(r,s) and b(p)(r;s), where 1 <= p < infinity. Moreover, by using the notion of Hausdorff measure of noncompactness, we ... -
Group-2-groupoids and 2G-crossed modules
(2019)In this paper, we introduce the notion of a group-2-groupoid as a group object in the category of 2-groupoids. We also obtain a 2G-crossed module by using the structure of a group-2-groupoid. Then we prove that the category ... -
A construction method for t-norms on bounded lattices
(Springer International Publishing Ag, 2019)In this paper, a construction method on a bounded lattice 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 has been ... -
Some notes on u-partıal order
(Kybernetika, 2019)In this paper, an equivalence on the class of uninorms on a bounded lattice is discussed. Some relationships between the equivalence classes of uninorms and the equivalence classes of their underlying t-norms and t-conorms ... -
