m-Eternal total bondage number in circulant graphs
(Işık University Press, 2025-05-01)An Eternal dominating set of a graph is defined as a set of guards located at vertices, required to protect the vertices of the graph against infinitely long sequences of attacks, such that the configuration of guards ... -
Designs arising from products of hypergraphs of cycles
(Işık University Press, 2025-05-01)In this paper, we have considered many standard graph products viz. cartesian product, direct product, strong product and lexicographic product, and extended these graph products to hypergraphs which are natural generalizations ... -
A variable sampling plan based on quadratic random decision function using classical and Bayesian estimates under type II hybrid censored samples
(Işık University Press, 2025-05-01)This article endeavors to develop a single variable sampling plan when the lifetime of product follows the exponential distribution. The sampling plan has been developed by assuming that the life test is under type II ... -
Modeling the effects of soil improvement on train induced random ground-borne vibrations
(Işık University Press, 2025-05-01)Ground-borne vibrations by railway trains are generated at the rail-wheel interface due to the passage of wheels and due to irregularities of wheels and tracks. These vibrations need to be predicted and controlled during ... -

Modified Sombor index of trees
(Işık University Press, 2025-05-01)The modified Sombor index of a graph G, denoted by ᵐSO(G), is defined as the sum of weights 1/√d2G(u)+d2G(v) of all edges uv of E(G), where dG(u) denotes the degree of a vertex u in G. In this paper we show that for any ... -
Estimation and tests with bivariate censored data
(Işık University Press, 2025-05-01)In this work, we study the asymptotic properties of the maximum likelihood estimator, for bivariate right censored data. We also propose a generalization of the likelihood ratio test and the chi-square test of fit, for ... -
On a class of constacyclic codes over the ring Z4[u]/< u² − 3 >
(Işık University Press, 2025-04-01)In this paper, λ-constacyclic codes and skew-λ-constacyclic codes over the ring R = Z4[u]/< u² − 3 > are studied for λ = 3 and 2 + 3u. Introducing new Gray maps from R to the copies of Z4, we observed that Gray images of ... -
The extended Legendre wavelets operational matrix of integration and its applications
(Işık University Press, 2025-04-01)In this paper, the general operational matrix of integration P based on the extended Legendre wavelets has been developed which generalizes the idea of the operational matrix of integration for µ = 2 given in [30]. A brief ... -
Distinguishing number in some aspects of dendrimers
(Işık University Press, 2025-04-01)The main purpose of the present study is to determine the distinguishing number of some dendrimers. The most known dendrimers such as Polyamidoamine (PAMAM), polylysine (PLL), Poly propyl ether imine (PETIM) and zinc ... -
