Analysis of discrete-time queue with two heterogeneous servers subject to catastrophes
(Işık University Press, 2014)This paper studies a discrete-time queueing system with two heterogeneous servers subject to catastrophes. We obtain explicit expressions for the steady-state probabilities at arbitrary epoch using displacement operator ... -
Multiple sequences in cone metric spaces
(Işık University Press, 2014-03-03)In this study, we introduce the ordinary and statistical convergence of double and multiple sequences in cone metric spaces. Moreover, the relationships between these convergence types are also invastigated. -
Partial complete controllability of deterministic semilinear systems
(Işık University Press, 2014-03-03)In this paper the concept of partial complete controllability for deterministic semilinear control systems in separable Hilbert spaces is investigated. Some important systems can be expressed as a first order differential ... -
Remotality of certain sets Lp(I,X)
(Işık University Press, 2014)Let X be a Banach space and let (I, ?, µ) be a measure space. For 1 ? p < ?, let Lp (I, X) denote the space of Bochner p?integrable functions defined on I with values in X. The object of this paper is to give sufficient ... -
Solution of two-dimensional heat and mass transfer equation with power-law temperature-dependent thermal conductivity
(Işık University Press, 2014-01-31)In this paper, we obtain the particular exact solutions of the two-dimensional heat and mass transfer equation with power-law temperature-dependent thermal conductivity using the Adomian’s decomposition method. In comparison ... -
"Yarman-36 makam tone-system" for Turkish art music
(Işık University Press, 2014)This study offers a mathematically rigorous, yet straightforward, fixed-pitch tuning strategy to the problem of adequate sounding and notating of essential Turkish makam genera, in contradistinction to the praxis-mismatched ... -
Fixed points of contractive set valued mappings with set valued domains on a metric space with graph
(Işık University Press, 2014)In this article we consider general contractive mappings of the form F : CB(X) ? CB(X), where CB(X) is the set of all nonempty closed and bounded subsets of a complete metric space X endowed with a graph G. We prove some ... -
Solving fractional diffusion and fractional diffusion-wave equations by Petrov-Galerkin finite element method
(Işık University Press, 2014)In the last few years, it has become highly evident that fractional calculus has been widely used in several areas of science. Because of this fact, their numerical solutions also have become urgently important. In this ... -
On trigonometric approximation in the space lp(x)
(Işık University Press, 2014)In this paper we have introduced two new class of numerical sequences, named almost monotone decreasing (increasing) upper second mean sequences. Moreover, we have presented some results on trigonometric approximation of ... -
Optimization of renewal input (a, c, b) policy working vacation queue with change over time and bernoulli schedule vacation interruption
(Işık University Press, 2014)This paper presents a renewal input single working vacation queue with change over time and Bernoulli schedule vacation interruption under (a, c, b) policy. The service and vacation times are exponentially distributed. The ... -
Domination integrity of total graphs
(Işık University Press, 2014)The domination integrity of a simple connected graph G is a measure of vulnerability of a graph. Here we determine the domination integrity of total graphs of path Pn, cycle Cn and star K1,n. -
Harmonic mappings related to the convex functions
(Işık University Press, 2014)The main purpose of this paper is to give the extent idea which was introduced by R. M. Robinson [5]. One of the interesting application of this extent idea is an investigation of the class of harmonic mappings related to ... -
On the solutions of fuzzy fractional differential equation
(Işık University Press, 2014)In this paper the exact and the approximate solutions of fuzzy fractional differential equation, in the sense of Caputo Hukuhara differentiability, with a fuzzy condition are constructed by using the fuzzy Laplace transform. ... -

Approximate optimality conditions
(Işık University Press, 2014)We propose in this paper a systematic study which is a variational approach of approximate optimality conditions in terms of Ekeland’s variational principle and some of its applications. Using a generalised differentiati ... -
On an extension of kummer-type II transformation
(Işık University Press, 2014)In the theory of hypergeometric and generalized hypergeometric series, Kummer’s type I and II transformations play an important role. In this short research paper, we aim to establish the explicit expression of e? x/2 2F2 ... -
