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 ... -
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 ... -
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 ... -

(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 ... -
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 ... -

Exact closed form solutions of compound Kdv Burgers’ equation by using generalized (G?/G) expansion method
(Işık University Press, 2023-10)In this investigation, the compound Korteweg-de Vries (Kd-V) Burgers equation with constant coefficients is considered as the model, which is used to describe the properties of ion-acoustic waves in plasma physics, and ... -
On quasi statistical convergence in gradual normed linear spaces
(Işık University Press, 2023-10)During the last few years, enormous works by different researchers have been carried out in summability theory by linking different notions of convergence of sequences. In the present paper, we introduce the concept of ... -
On the metric dimension of a class of planar graphs
(Işık University Press, 2023-10)Let H = (V, E) be a non-trivial connected graph with vertex set V and edge set E. A set of ordered vertices Rm from V (H) is said to be a resolving set for H if each vertex of H is uniquely determined by its vector of ... -
Strong asymptotic stability for a coupled system of degenerate wave equations with only one fractional feedback
(Işık University Press, 2023-10)We prove the well-posedness and study the strong asymptotic stability of a coupled system of degenerate wave equations with a fractional feedback acting on one end only. -
Modeling disease transmission dynamics with random data and heavy tailed random effects: the Zika case
(Işık University Press, 2023-10)In this study, we investigate a compartmental model of Zika Virus transmission under random effects. Random effects enable the analysis of random numerical characteristics of transmission, which cannot be modeled through ... -

(Işık University Press, 2023-07)In recent years, J. R. Kider and Z.A. Hussain have introduced the notion of standard fuzzy metric space and some basic properties were proved. In this paper, we generalize this notion to the setting of single valued ... -
Minimum generating sets for complete graphs
(Işık University Press, 2023-07)Let G be a graph with edges labeled by ideals of a commutative ring R with identity. Such a graph is called an edge-labeled graph over R. A generalized spline is a vertex labeling so that the difference between the labels ... -
Extinction of cholera using deterministic and stochastic models incorporating vigilant human compartment
(Işık University Press, 2023-07)We study the effect of vaccination, sanitation and public health sensitization as prevention and control measures of cholera in deterministic and stochastic frameworks. To achieve this, a deterministic mathematical model ... -
