On relation of two processes with independent increments applied in queueing systems
(Işık University Press, 2017)
In the paper, by using two processes ξt and η (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 ξt, t ≥ 0, ...
Streamline upwind/Petrov Galerkin solution of optimal control problems governed by time dependent diffusion-convection-reaction equations
(Işık University Press, 2017)
The streamline upwind/Petrov Galerkin (SUPG) finite element method is studied for distributed optimal control problems governed by unsteady diffusion-convectionreaction equations with control constraints. We derive stability ...
Adaptive methods for solving operator equations by using frames of subspaces
(Işık University Press, 2017)
In this paper, using a frame of subspaces we transform an operator equation to an equivalent `2-problem. Then, we propose an adaptive algorithm to solve the problem and investigate the optimality and complexity properties ...
B-Spline collocation method for numerical solution of nonlinear kawahara and modified kawahara equations
(Işık University Press, 2017)
In this paper, a collocation method is applied for solving the Kawahara and modified Kawahara equations. For the spatial discretization, we use the sextic B-spline collocation (SBSC) method on uniform meshes, finite ...
Dirichlet series and approximate analytical method for the solution of mhd boundary layer flow of casson fluid over a stretching/shrinking sheet
(Işık University Press, 2017-01-25)
The paper presents analytical and semi-numerical solution for magnetohydrodynamic (MHD) boundary layer flow of Casson fluid over a exponentially permeable shrinking sheet. The governing partial differential equations of ...
Existence and multiple positive solutions to systems of differential equations of fractional order
(Işık University Press, 2017-03-07)
We show under some conditions the existence and multiplicity of positive solutions for a system of differential equations of fractional order, subject to two-point boundary conditions by applying the fixed point index ...
Generalized α − ψ-geraghty multivalued mappings on b-metric spaces endowed with a graph
(Işık University Press, 2017-01-12)
In this paper, we provide some conditions for the existence of a coincidence point of single-valued and multivalued mappings involving generalized α − ψ-Geraghty contractions endowed with a graph. Our main results improve ...
Partitioning a graph into monopoly sets
(Işık University Press, 2017)
In a graph G = (V, E), a set M ⊆ V (G) is said to be a monopoly set of G if every vertex v ∈ V − M has, at least, d(v)/2 neighbors in M. The monopoly size of G, denoted by mo(G), is the minimum cardinality of a monopoly ...
Residual closeness for helm and sunflower graphs
(Işık University Press, 2017-06-06)
Vulnerability is an important concept in network analysis related with the ability of the network to avoid intentional attacks or disruption when a failure is produced in some of its components. Often enough, the network ...
The perturbation to non-Markovian equation of motion corresponding to coherent and quadrature non-Markovian SSES
(Işık University Press, 2017)
In this paper, we derive the perturbation and post Markovian perturbation to non-Markovian equation of motion(NMEM) that correspond to coherent and quadrature non-Markovian stochastic Schr¨odinger equations (SSE). In that ...
