Modified bisection algorithm in estimating the extreme value index under random censoring
(Işık University Press, 2023-10)
The Generalized Pareto Distribution (GPD) has long been employed in the theories of extreme values. In this paper, we are interested by estimating the extreme value index under censoring. Using a maximum likelihood estimator ...
Stability analysis of a fractional order coronavirus(COVID-19) epidemic model
(Işık University Press, 2023-10)
In this paper a six-compartmental coronavirus(COVID-19) epidemic model is developed. We have divided the total population into five classes, namely susceptible, exposed, infected, treatment, recovered and the concentration ...
An iterative approach for fuzzy multi objective linear fractional programming problem
(Işık University Press, 2023-10)
In this paper, we introduce an iterative method for the solution of fully fuzzy single and multi objective linear fractional programming problems with out converting them into equivalent crisp forms. By introducing fuzzy ...
Some Hermite–Hadamard inequalities involving weighted integral operators via (h, s, m)-convex functions
(Işık University Press, 2023-10)
In this work, we establish new integral inequalities of Hermite–Hadamard type, within the framework of generalized integrals, which contain the Riemann–Liouville fractional integrals as particular case. We use a definition ...
Solution of the optimal program trajectory and control of the discretized equation of motion of sucker-rod pumping unit in a newtonian fluid
(Işık University Press, 2023-10)
In this paper, the problem of construction of the optimal trajectory and control for oscillatory systems with liquid dampers in the movement of the sucker-rod pumping unit is considered. Firstly, the equation of motion is ...
Domination changing and unchanging signed graphs upon the vertex removal
(Işık University Press, 2023-10)
A subset S of V (?) is a dominating set of ? if |N?(v) ? S| > |N?(v) ? S| for all v ? V ? S. This article is to start a study of those signed graphs that are stable and critical in the following way: If the removal of an ...
Topological indices of total graph of the ring Z? × Zm
(Işık University Press, 2023-10)
In this paper, we compute some distance-based topological indices namely Wiener index, hyper Wiener index and reverse Wiener index of the total graph of the ring Zn × Zm. We also compute some eccentricity-based topological ...
Laceability properties in the image graph of Prism graphs
(Işık University Press, 2023-10)
A connected graph G is termed Hamiltonian-t-laceable if there exists in it a Hamiltonian path between every pair of vertices u and v with the property d(u, v) = t, 1 ? t ? diam(G), where t is a positive integer. In this ...
Certain subclasses of analytic function by S?l?gean q-differential operator
(Işık University Press, 2023-10)
The theory of q-analysis has many applications in various sub-fields of mathematics and quantum physics. In the present article, we define the class Tn(?, ?; q) using the S?l?gean q-differential operator. For functions ...
A multi criteria group decision making approach based on fuzzy measure theory to assess the different gene regions used in rodent species
(Işık University Press, 2023-10)
Many mitochondrial and nuclear gene regions are used in phylogenetic and taxonomic studies to investigate the historical background of the species and to present the hierarchy of the species. In this paper, we consider the ...
