Simulation studies for credibility-based multi-objective linear programming problems with fuzzy parameters
(Işık University Press, 2020)
In this paper, hybrid credibility-based multi-objective linear programming models are provided to optimize expected values of objective functions subject to fuzzy chance-constraints. Triangular or non-linear fuzzy numbers ...
On ruled non-degenerate surfaces with Darboux frame in Minkowski 3-space
(Işık University Press, 2020)
In this paper, ruled non-degenerate surfaces with respect to Darboux frame are studied. Characterization of them which are related to the geodesic torsion, the normal curvature and the geodesic curvature with respect to ...
Fuzzy perfect equitable domination excellent trees
(Işık University Press, 2020)
A set D of vertices of a fuzzy graph G is a Perfect Dominating set if every vertex not in D is adjacent to exactly one vertex in D. In this paper, we discuss the concept of equitable excellent fuzzy graph, fuzzy equitable ...
Partition energy of some trees and their generalized complements
(Işık University Press, 2020)
Let G = (V, E) be a graph and Pk = {V1, V2, . . . , Vk} be a partition of V . The k-partition energy of a graph G with respect to partition Pk is denoted by EPk (G) and is defined as the sum of the absolute values of ...
Computing integer powers for a certain family of skew circulant matrices
(Işık University Press, 2020)
In this paper, we derive a formula for the entries of the integer powers of a certain type of skew circulant matrices of odd and even order in terms of the Chebyshev polynomials of the first and second kind. Finally, we ...
Applications of chebyshev polynomials on λ-pseudo bi-starlike and λ-pseudo bi-convex functions with respect to symmetrical points
(Işık University Press, 2020)
The purpose of this work is to use the Chebyshev polynomial expansions to seek upper bounds for the second and third coefficients of functions belongs to a subclass of λ-pseudo bi-starlike and λ-pseudo bi-convex functions ...
Numerical range and sub-self-adjoint operators
(Işık University Press, 2020)
In this paper, we show that the numerical range of a bounded linear operatör T on a complex Hilbert space is a line segment if and only if there are scalars λ and µ such that T ∗ = λT + µI, and we determine the equation ...
Fuzzy parameterized fuzzy soft matrices and their application in decision-making
(Işık University Press, 2020)
In this study, we define the concept of fuzzy parameterized fuzzy soft matrices (fpfs-matrices) and present some of their basic properties. By using fpfs-matrices, we then suggest a new algorithm, i.e. Prevalence Effect ...
Estimation of the location and scale parameters of moyal distribution
(Işık University Press, 2020)
In this study, we estimate the parameters of the Moyal distribution by using well-known and widely-used maximum likelihood (ML) and method of moments (MoM) methodologies. The ML estimators of the location and scale parameters ...
Generalized fixed point results with multi-valued mappings
(Işık University Press, 2020)
In this article we deduce fixed point results for multi-valued contraction mappings. We primarily established two fixed results. One of them is the generalization of Nadler’s contraction and the other result is the ...
