Similar ruled surfaces with variable transformations in minkowski 3-space E3 1
(Işık University Press, 2015)In this study, we consider the notion of similar ruled surface for timelike and spacelike ruled surfaces in Minkowski 3-space E31. We obtain some properties of these special surfaces in E31 and show that developable ruled ... -
Study of the first boundary value problem for a fourth order parabolic equation in a nonregular domain of
(Işık University Press, 2015)This paper is concerned with the extension of solvability results obtained for a fourth order parabolic equation, set in a nonregular domain of R3 obtained in [1], to the case where the domain is cylindrical, not with ... -
Shadow of operators on frames
(Işık University Press, 2015)Aldroubi introduced two methods for generating frames of a Hilbert space H. In one of his method, one approach is to construct frames for H which are images of a given frame for H under T ? B (H, H), a collection of all ... -
Modified differential transform method for singular lane-emden equations in integer and fractional order
(Işık University Press, 2015)In the present work the modified differential transform method, incorporating the Adomian polynomials into the differential transform method(DTM), is used to solve the nonlinear and singular Lane-Emden equations in integer ... -
Distance majorization sets in graphs
(Işık University Press, 2015)Let G = (V, E) be a simple graph. A subset D of V (G) is said to be a distance majorization set (or dm - set) if for every vertex u ? V ? D, there exists a vertex v ? D such that d(u, v) ? deg(u) + deg(v). The minimum ... -
Codes correcting key errors
(Işık University Press, 2015)The objective of coding theory is to protect a message going through a noisy channel. The nature of errors that cause noisy channel depends on different factors. Accordingly codes are needed to develop to deal with different ... -
Solvability of second order delta-nabla p-laplacian m-point eigenvalue problem on time scales
(Işık University Press, 2015)In this paper, we are concerned with the following eigenvalue problem of m-point boundary value problem for p-Laplacian dynamic equation on time scales, (?p(u?(t)))? + ?h(t)f(u(t)) = 0, t ? [a, b]T’ u(a) ? u?(a) = ... -

Graphs with equal domination and independent domination number
(Işık University Press, 2015)A set S of vertices of a graph G is an independent dominating set of G if S is an independent set and every vertex not in S is adjacent to a vertex in S. The independent domination number of G, denoted by i(G), is the ... -
Weak convergence theorem for the ergodic distribution of a random walk with normal distributed interference of chance
(Işık University Press, 2015)In this study, a semi-Markovian random walk process (X(t)) with a discrete interference of chance is investigated. Here, it is assumed that the ?n, n = 1, 2, 3, ..., which describe the discrete interference of chance are ... -
Derivative free multilevel optimization
(Işık University Press, 2015)Optimization problems with different levels arise by discretization of ordinary and partial differential equations. We present a trust-region based derivative-free multilevel optimization algorithm. The performance of the ... -

Fixed points on T0-QPMS
(Işık University Press, 2014-05-05)In this paper, we proved some fixed point results for maps in quasi-pseudometric spaces. The theorems are a generalization of the results presented in [3]. -
A mathematical model on genetic dihybrid and multihybrid
(Işık University Press, 2014-04-05)Human and, in fact, every animal or plant contains many gene oriented traits. This means that the traits depend on chromosomes and are mainly directed by DNA sequence. On the other hand, a particular trait of any species ... -
On controlled poisson processes
(Işık University Press, 2014)We consider a special class of two-dimensional Markov processes, finding the relationship between transition probabilities of two such classes. -
