Cooperative two-stage network dea: a goal programming approach
(Işık University Press, 2019-01-05)
In this study, we present a two-stage data envelopment analysis method dealing with efficiency evaluation of decision making units with network structure. The key point of the study is that the suggested model optimizes ...
One-dimensional cutting stock problem with divisible items: a case study in steel industry
(Işık University Press, 2019)
This paper considers the one-dimensional cutting stock problem (1D-CSP) with divisible items, which arises in the steel industries. While planning the steel cutting operations, each item can be divided into smaller pieces, ...
Exponential domination of tree related graphs
(Işık University Press, 2019)
The well-known concept of domination in graphs is a good tool for analyzing situations that can be modeled by networks. Although a vertex in the graph can exert influence on, or dominate, all vertices in its immediate ...
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 ...
Numerical solution of time-fractional order Fokker-Planck equation
(Işık University Press, 2019)
In this article, new iterative method (NIM) is employed to find the numerical solution of linear and nonlinear time-fractional order Fokker-Planck equation (FPE), which is applied in many fields of engineering and applied ...
Generalization of some inequalities for the polar derivative of polynomials with restricted zeros
(Işık University Press, 2019)
If p(z) is a polynomial of degree n, then Govil [N.K. Govil, Some inequalities for derivative of polynomials, J. Approx. Theory, 66 (1991) 29-35.] proved that if p(z) has all its zeros in vertical bar z vertical bar <= k, ...
On some properties of normal ?-ideals in normal ?-semigroups
(Işık University Press, 2019)
We introduce the concept of normal ?-ideal and bi-?-ideal in normal ?semigroups. We characterize the (normal) ?-semigroup and normal regular ?-semigroup in terms of elementary properties of bi-?-ideal proving the various ...
Hydrodynamic limit of the Boltzmann-Monge-Ampere system
(Işık University Press, 2019)
This paper investigates the hydrodynamic limit of the Boltzmann-MongeAmpere system in the so-called quasineutral regime and more precisely the convergence of the Boltzmann-Monge-Ampere system to the Euler equation by using ...
Existence of three solutions for impulsive fractional differential systems through variational methods
(Işık University Press, 2019)
This paper is devoted to the study of the multiplicity results of existence of solutions for a class of impulsive fractional differential systems. Indeed, we will use variational methods for smooth functionals, defined on ...
Analytic approach for love wave dispersion in an inhomogeneous layer lying over an irregular porous half-space
(Işık University Press, 2019)
The present work examines the possibility of Love wave dispersion in an irregular interface of two different media expressively as an inhomogeneous layer and porous half-space. Dispersion equation has been computed in a ...
