One-parameter homothetic motion in the Minkowski 3-space
(Işık University Press, 2016)A one-parameter homothetic motion in three-dimensional Minkowski space is defined by means of the Hamilton operators. We study some properties of this motion and show that it has only one pole point at every instant t. We ... -
The connected detour monophonic number of a graph
(Işık University Press, 2016)For a connected graph G = (V, E) of order at least two, a chord of a path P is an edge joining two non-adjacent vertices of P. A path P is called a monophonic path if it is a chordless path. A longest x ? y monophonic path ... -
On curves of constant breadth in G¹?
(Işık University Press, 2016)In this work, differential equations characterizing curves of constant breadth have been given in pseudo-Galilean space G¹?. The special cases related to these differential equations have been studied in G¹?. -
Integrity and domination integrity of gear graphs
(Işık University Press, 2016-06-30)C.A. Barefoot, et. al. [4] introduced the concept of the integrity of a graph. It is an useful measure of vulnerability and it is defined as follows. I(G) = min{|S| + m(G ? S) : S ? V (G)}, where m(G ? S) denotes the order ... -
On generalization of weierstrass approximation theorem for a general class of polynomials and generating functions
(Işık University Press, 2016)Here, in this work we present a generalization of the Weierstrass Approximation Theorem for a general class of polynomials. Then we generalize it for two variable continuous function F(x, t) and prove that on a rectangle ... -
Using implicit relation to prove common coupled fixed point theorems for two hybrid pairs of mappings
(Işık University Press, 2016)Using implicit relation we establish two common coupled fixed point theorems under the conditions of weakly commutativity and w?compatibility on a complete metric space, which is not partially ordered. We do not use the ... -
On the curvature theory of non-null cylindrical surfaces in Minkowski 3-space
(Işık University Press, 2016)This paper presents the curvature theory of non-null cylindrical surfaces in Minkowski 3-space. The definition of the line of striction and generator trihedron for cylindrical surfaces in Minkowski 3-space are given. The ... -
Jacobsthal family modulo m
(Işık University Press, 2016)In this study, we investigate sets of remainder of the Jacobsthal and JacobsthalLucas numbers modulo m for some positive integers m. Also some properties related to these sets and a new method to calculate the length of ... -
On the distribution of the maximum of sums of a sequence of independent and identically distributed random variables
(Işık University Press, 2016)The authors find in terms of generating functions the distribution of the maximum of sums of independent and identically distributed random variables with no negative jumps different from ?1. -
Trivially extendable graphs
(Işık University Press, 2015-03-24)Let G be a simple graph. Let k be a positive integer. G is said to be k-extendable if every independent set of cardinality k is contained in a maximum independent set of G. G is said to be trivially extendable if G is not ... -
A efficient computational method for solving stochastic itô-volterra integral equations
(Işık University Press, 2015)In this paper, a new stochastic operational matrix for the Legendre wavelets is presented and a general procedure for forming this matrix is given. A computational method based on this stochastic operational matrix is ... -
Quadratic spline solution of calculus of variation problems
(Işık University Press, 2015)In this paper, we developed numerical method of order O(h2) and based on quadratic polynomial spline function for the numerical solution of class of two point boundary value problems arising in Calculus of Variation. The ... -

(Işık University Press, 2015)Here we denote a diameter six tree by (a0; a1, a2, . . . , am; b1, b2, . . . , bn; c1, c2, . . . , cr), where a0 is the center of the tree; ai, i = 1, 2, . . . , m, bj , j = 1, 2, . . . , n, and ck, k = 1, 2, . . . , r are ... -
Linear retrial inventory system with second optional service under mixed priority service
(Işık University Press, 2015)The present paper deals with a generalization of the homogeneous single server finite source retrial inventory system with two classes of customers - one with high priority customer and the other with low priority customer. ... -
Computational complexity of domination integrity in graphs
(Işık University Press, 2015)In a graph G, those dominating sets S which give minimum value for |S| + m(G?S), where m(G?S) denotes the maximum order of a component of G?S, are called dominating integrity sets of G (briefly called DI-sets of G). This ... -
Extensions of Kannan's fixed point results
(Işık University Press, 2015)In this article, we essentially proved some fixed point results for contractive maps type in quasi-pseudometric spaces. The presented theorems are formulated in an asymmetric setting and therefore generalize some existing ... -
On the hadamard product of balancing matrix and balancing matrix
(Işık University Press, 2015)In this paper, the matrix QnB ? Q?nB which is the Hadamard product of both balancing QnB matrix and balancing Q?nB matrix is introduced. Some properties of the Hadamard product of these matrices are investigated. A different ... -
Monomial geometric programming with fuzzy relation equation constraints regarding max-bounded difference composition operator
(Işık University Press, 2015)In this paper, an optimization model with an objective function as monomial subject to a system of the fuzzy relation equations with max-bounded difference (maxBD) composition operator is presented. We firstly determine ... -
An intelligent decision support tool for early diagnosis of functional pituitary adenomas
(Işık University Press, 2015)In this work, a web based integrated Medical Decision Support System (MDSS) tool for mainly early diagnosis of functional pituitary adenomas (i.e., somatotrophinoma, corticotrophinoma and prolactinoma) is developed. In the ... -
New results on cyclic nonlinear contractions in partial metric spaces
(Işık University Press, 2015)In this paper we study the concept of non-linear cyclic Kannan and Chatterjea contractions in partial metric spaces and we prove some new theorems on fixed point for these types of mappings extending some fixed point ...
