A new heuristic algorithm for multiple traveling salesman problem
(Işık University Press, 2017)The Multiple Traveling Salesman Problem (mTSP) is a combinatorial optimization problem in NP-hard class. The mTSP aims to acquire the minimum cost for traveling a given set of cities by assigning each of them to a different ... -
Numerical solution of the interrelated differential equation of motion in phonon engineering
(Işık University Press, 2017)In this work, we study numeric calculations of phonon modes in nanostructures. The motion equation of atoms in a crystal with some simplification, results in a second order ordinary differential equation and two interrelated ... -
On complex multiplicative integration
(Işık University Press, 2017)In the present paper, we extend the multiplicative integral to complex-valued functions of complex variable. The main difficulty in this way, that is, the multi-valued nature of the complex logarithm is avoided by division ... -
Graphs cospectral with multicone graphs KW 5 L(P)
(Işık University Press, 2017)E. R. van Dam and W. H. Haemers [15] conjectured that almost all graphs are determined by their spectra. Nevertheless, the set of graphs which are known to be determined by their spectra is small. Hence, discovering infinite ... -
Certain integral transforms and fractional integral formulas for the extended hypergeometric functions
(Işık University Press, 2017)In this present paper, we derive various integral transforms, including Euler, Varma, Laplace, and Whittaker integral transforms for the extended hypergeometric functions which has recently been introduced by Choi et al.[3]. ... -
Solutions of complex equations with adomian decomposition method
(Işık University Press, 2017)In this study, first order linear complex differential equations have been solved with adomian decomposition method. -
On approximate methods for fractal vehicular traffic flow
(Işık University Press, 2017)In this paper, we find the approximate solutions for partial differential equations arising in fractal vehicular traffic flow by using the local fractional Laplace decomposition method (LFLDM) and local fractional series ... -
On relation of two processes with independent increments applied in queueing systems
(Işık University Press, 2017)In the paper, by using two processes ?t and ? (t), t ? 0 with independent increments, one of which is without negative overshoots and the second one is homogeneous in time, we study a homogeneous Markov process ?t, t ? 0, ... -
Combining genetic algorithm and Sinc-Galerkin method for solving an inverse diffusion problem
(Işık University Press, 2017)A numerical approach combining the use of a genetic algorithm with the solution of the Sinc-Galerkin method is proposed for the determination of an unknown time-dependent diffusivity a(t) in an inverse diffusion problem ... -
Coincidence and common fixed point theorems for faintly compatible maps
(Işık University Press, 2017)The paper is aimed to generalize and improve the results of Bisht and Shahzad [Faintly compatible mappings and common fixed points, fixed point theory and applications, 2013, 2013:156]. The significance of this paper lies ... -
Common coupled fixed point theorem under weak ? ? ? contraction for hybrid pair of mappings with application
(Işık University Press, 2017)We establish a common coupled fixed point theorem for hybrid pair of mappings under weak ? ? ? contraction on a non-complete metric space, which is not partially ordered. It is to be noted that to find coupled coincidence ... -

On certain topological indices of the derived graphs of subdivision graphs
(Işık University Press, 2016-03-11)The derived graph [G]† of a graph G is the graph having the same vertex set as G, with two vertices of [G]† being adjacent if and only if their distance in G is two. Topological indices are valuable in the study of QSAR/QSPR. ... -

(Işık University Press, 2017)The problem of construction the general solution of the generalized matrix Sylvester equation is considered. Conditions of existence of solution of this equation are obtained and the algorithm for construction of this ... -
Some results on the distance r-b-coloring in graphs
(Işık University Press, 2016)Given a positive integer r, two vertices u, v ? V (G) are r- independent if d(u, v) > r. A partition of V (G) into r-independent sets is called a distance r-coloring. A study of distance r-coloring and distance r-b-coloring ... -
Stability of a functional equation in complex banach spaces
(Işık University Press, 2016-03-14)Using fixed point technique, in the present paper , we wish to examine generalization of the Hyers-Ulam-Rassias stability theorem for the functional equations f ( 2 x + i y ) + f ( x + 2 i y ) = 4 f ( x + i y ) + f ( x ) ... -
