On super (a, d)-eat valuation of subdivided caterpillar
(Işık University Press, 2019)Let G = (V (G), E(G)) be a graph with v = |V (G)| vertices and e = |E(G)| edges. A bijective function ? : V (G) ? E(G) ? {1, 2, . . . , v + e} is called an (a, d)- edge antimagic total (EAT) labeling(valuation) if the ... -
On star chromatic number of prism graph families
(Işık University Press, 2019)In this paper, we find the star chromatic number ?s for the central graph of prism graph C(Yn), line graph of prism graph L(Yn), middle graph of prism graph M(Yn) and the total graph of prism graph T(Yn) for all n ? 3. -
Global color class domination partition of a graph
(Işık University Press, 2019)Color class domination partition was suggested by E. Sampathkumar and it was studied in [1]. A proper color partition of a finite, simple graph G is called a color class domination partition (or cd-partition) if every color ... -
SK indices, forgotten topological indices and Hyper Zagreb index of Q operator of carbon nanocone
(Işık University Press, 2019)Carbon nanocones are conical structures made from carbon and they have one dimension of order one micrometer. The physical features of these structures can be easily understood by exploiting topological indices. In this ... -
On the average lower 2-domination number of a graph
(Işık University Press, 2019)Computer scientists and network scientists want a speedy, reliable, and nonstop communication. In a communication network, the vulnerability measures the resistance of the network to disruption of operation after the failure ... -

Existence of nonoscillatory solutions for second-order nonlinear neutral differential equations with variable delays
(Işık University Press, 2019)In this work, an attempt is made to discuss the existence of nonoscillatory solutions of second order nonlinear neutral differential equations with variable delays. The main tools are Lebesgue’s dominated convergence theorem ... -
Distance spectra of some graph operations and some new distance equienergetic graphs of diameter 3
(Işık University Press, 2019)Two graphs of same order are said to be distance equienergetic if their distance energies are same. In this paper, we first give a partial insight on the distance spectrum of Mycielskian graphs and then we focus on ... -
On the spectra of cycles and paths
(Işık University Press, 2019)Energy of a graph was defined by E. Hückel as the sum of absolute values of the eigenvalues of the adjacency matrix during the search for a method to obtain approximate solutions of Schr¨odinger equation which include the ... -

A descent PRP conjugate gradient method for unconstrained optimization
(Işık University Press, 2019)It is well known that the sufficient descent condition is very important to the global convergence of the nonlinear conjugate gradient methods. Also, the direction generated by a conjugate gradient method may not be a ... -
Blind deconvolution using shearlet -tv regularization
(Işık University Press, 2019)In this article we propose two minimization models for blind deconvolution. In the first model, we use shearlet transform as a regularization term for recovering image. Also total variation method is used as a regularization ...
