A novel stochastic approach to buffer stock problem
(Işık University Press, 2024-04)In this paper, the stochastic fluctuation of buffer stock level at time t is investigated. Therefore, random walk processes X(t) and Y (t) with two specific barriers have been defined to describe the stochastic fluctuation ... -
Applications of the generalized homogeneous q-shift operator in q-polynomials

Modeling internet access at home by fractional calculus and a correlation analysis with human development index
(Işık University Press, 2024-04)In this study, we modeled broadband internet access at home data and investigated the relationship between the human development index and internet access in countries. The broadband Internet access at home is modeled using ... -
The Y- index and coindex of VC?C?[p, q] and HC?C?[p, q] nanotubes
(Işık University Press, 2024-04)The Y-index and coindex are degree based molecular structure descriptors that have been shown to give a high degree of predictability compare to Zagreb indices and F-index and their coindices for some physicochemical ... -
On dimension of some finite algebraic graphs of finite rings
(Işık University Press, 2024-01)Suppose that ?? (Zp1p2···p? ) is a graph with the vertex set of nonzero zerodivisors of the finite ring Zp1p2...p? , where ? > 1, and x ? y is an edge if and only if x and y are ?-prime, where ? = {p1, p2, . . . , p?} is ... -
New notions on ideal convergence of triple sequences in neutrosophic normed spaces
(Işık University Press, 2024-01)The usual convergence of sequences has many generalizations with the aim of providing deeper insights into the summability theory. In this paper, following a very recent and new approach, we introduce the notion of I3 and ... -
Certain expansion formulae involving incomplete I-functions
(Işık University Press, 2024-01)The aim of this paper is to derive the expansion formulae for the incomplete I-function. Furthermore, their special cases are illustrated in terms of various types of special functions (incomplete I-function, incomplete ... -
Hypergeometric function representation of the roots of a certain cubic equation
(Işık University Press, 2024-01)The aim in this note is to obtain new hypergeometric forms for the functions (?z ? 1 ? ?z) b ± (?z ? 1 ? ?z)?b, (?z ? 1 + ?z)b ± (?z ? 1 + ?z)?b, where b is an arbitrary parameter, in terms of Gauss hypergeometric functions. ... -

(Işık University Press, 2024-01)This paper deals with the investigation of M/M/3 queueing model under the provision of service rates of jobs depend upon the load of the jobs arrived in the system. The customers (jobs) arrive in the system in Poisson ... -
Numerical solution for anti-persistent process based stochastic integral equations
(Işık University Press, 2024-01)In this article, we propose the shifted Legendre polynomial solutions for anti-persistent process based stochastic integral equations. The operational matrices for stochastic integration and fractional stochastic integration ... -
A stochastic maximum principle for general mean-field backward doubly stochastic control
(Işık University Press, 2024-01)In this paper we study the optimal control problems of general MckeanVlasov for backward doubly stochastic differential equations (BDSDEs), in which the coefficients depend on the state of the solution process as well as ... -
Novel concepts in vague incidence graphs with application
(Işık University Press, 2024-01)Fuzzy graph (FG) models enjoy the ubiquity of being in natural and humanmade structures, namely dynamic process in physical, biological, and social systems. As a result of inconsistent and indeterminate information inherent ... -
Quasi-block Toeplitz matrix in matlab
(Işık University Press, 2024-01)In this paper we try to approximate any properties of quasi-block Toeplitz matrix (QBT), by means of a finite number of parameters. A quasi-block Toeplitz (QBT) matrix is a semi-infinite block matrix of the kind F = T(F) ... -
Total edge irregularity strength of join of path and complement of a complete graph
(Işık University Press, 2024-01)An edge irregular total k-labeling of a graph G is a labeling of the vertices and edges of G with labels from the set {1, 2, ..., k} in such a way that any two different edges have distinct weights. The weight of an edge ... -
Analyzing the effects of temperature and human movement on malaria disease transmission dynamics
(Işık University Press, 2024-01)Vector borne diseases like malaria are spreading worldwide. They have become a major cause of morbidity and mortality. Malaria cases are increasing due to the human movement from one place to the other. Changing temperature ... -
