Hybrid number matrices
(2023)The aim of this study is to investigate some properties of hybrid number matrices. Firstly, we introduce hybrid numbers with some of their properties. Then we prove that any hybrid number has a 2 x 2 complex matrix ... -

On the injectivity with respect to q of the Lupaş q-transform
(Taylor & Francis Ltd., 2023)The Lupas q-transform has first appeared in the study of the Lupas q-analogue of the Bernstein operator. Given 0 < q < 1 and f is an element of C[0, 1], the Lupas q-transform is defined by Lambda(q)(f; x) Pi(infinity)(k=0) ... -
Determination of the smallest-greatest uni-nullnorms and null-uninorms on an arbitrary bounded lattice L
(World Stientific Publishing, 2023)In this paper, we study uni-nullnorms and null-uninorms on bounded lattices, which are generalizations of uninorms, nullnorms, t-norms and t-conorms. We construct two uni-nullnorms and two null-uninorms on a bounded lattice ... -
Sensitivity analysis and random dynamics for a mathematical model of tuberculosis transmission
(Taylor & Francis Ltd., 2023)In this study, a recent mathematical model for the spread of tuberculosis disease will be analyzed under random conditions. The sensitivity of the basic reproduction number to the changes in the parameters will be analyzed ... -
Comparison of a random model of Hand-Foot-Mouth Disease model with Gaussian and Laplacian parameters
(Gumushane University, 2022)In this study, we investigate the transmission dynamics of Hand-Foot-Mouth disease (HFMD) using a differential equation system with random parameters. We transform the parameters of the existing deterministic model into ... -
Subsethood measure for picture fuzzy sets and its applications on multicriteria decision making
(Gumushane University, 2022)Picture fuzzy set is a direct generalization of intuitionistic fuzzy set and is therefore more capable of dealing with uncertainty while working on real life problems. The concept of inclusion is a subject that is frequently ... -
An existing problem for symmetric design: Bruck Ryser Chowla Theorem
(Sakarya University, 2022)Symetric designs are interesting objects of combinatorics, and have some relations with coding theory, difference sets, geometry and finite group theory. They have applications on statistics and design experiments. In ... -
