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 λ : V (G) ∪ E(G) ↔ {1, 2, . . . , v + e} is called an (a, d)- edge antimagic total (EAT) labeling(valuation) if the ...
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 ...
On starlike harmonic functions
(Işık University Press, 2019)
Uniformly starlike univalent functions introduced by Goodman and we develop this idea over harmonic functions. We introduce a subclass of harmonic univalent functions which are fully starlike and uniformly starlike also. ...
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 star chromatic number of prism graph families
(Işık University Press, 2019)
In this paper, we find the star chromatic number χs 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.
Existence of nonoscillatory solutions of second-order neutral differential equations
(Işık University Press, 2019)
We obtain some sufficient conditions for the existence of nonoscillatory solutions of nonlinear second order neutral differential equation with forcing term. Our results improve and extend some existing results. Examples ...
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 ...
On the solution approaches of the band collocation problem
(Işık University Press, 2019)
This paper introduces the first genetic algorithm approach for solving the Band Collocation Problem (BCP) which is a combinatorial optimization problem that aims to reduce the hardware costs on fiber optic networks. This ...
Effects of ground water table and ground inclination on train induced ground-borne vibrations
(Işık University Press, 2019)
Passage of the train wheels induces ground-borne vibrations at the railwheel interface, where the main contribution is due to the axle loads moving on irregular track and wheel interface. These vibrations can cause problems ...
Calculation of stresses in a watered layer
(Işık University Press, 2019)
In the paper the analitical expressions for computing stresses in a watered layer have been obtained. It is not required to solve endless systems of equations.
