On solution of modified matrix Sylvester equation
(Işık University Press, 20180822)In the paper, the approach connected with the linear matrix inequalities for construction of solution of the modified Sylvester matrix equations, is used. The essence of the approach consists in replacement the initial ... 
A descent PRP conjugate gradient method for unconstrained optimization
(Işık University Press, 20171010)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, 20171009)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 ... 
Cooperative twostage network dea: a goal programming approach
(Işık University Press, 20190105)In this study, we present a twostage 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 ... 
Existence and multiplicity of weak solutions for perturbed Kirchhoff type elliptic problems with hardy potential
(Işık University Press, 20170908)In this paper, we prove the existence of at least three weak solutions for a doubly eigenvalue elliptic systems involving the pbiharmonic equation with Hardy potential of Kirchhoff type with Navier boundary condition. ... 
Hydrodynamic limit of the BoltzmannMongeAmpere system
(Işık University Press, 20171211)This paper investigates the hydrodynamic limit of the BoltzmannMongeAmpere system in the socalled quasineutral regime and more precisely the convergence of the BoltzmannMongeAmpere system to the Euler equation by using ... 
Generalization of some inequalities for the polar derivative of polynomials with restricted zeros
(Işık University Press, 20170911)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) 2935.] proved that if p(z) has all its zeros in vertical bar z vertical bar <= k, ... 
Onedimensional cutting stock problem with divisible items: a case study in steel industry
(Işık University Press, 20180115)This paper considers the onedimensional cutting stock problem (1DCSP) 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, 20170825)The wellknown 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 ... 
On some properties of normal Γideals in normal Γsemigroups
(Işık University Press, 20170703)We introduce the concept of normal Γideal and biΓideal in normal Γsemigroups. We characterize the (normal) Γsemigroup and normal regular Γsemigroup in terms of elementary properties of biΓideal proving the various ... 
Numerical solution of timefractional order FokkerPlanck equation
(Işık University Press, 20170714)In this article, new iterative method (NIM) is employed to find the numerical solution of linear and nonlinear timefractional order FokkerPlanck equation (FPE), which is applied in many fields of engineering and applied ... 
Geometric function optimization subject to mixed fuzzy relation inequality constraints
(Işık University Press, 20170714)In this paper, the mixed fuzzy relation geometric programming problem is considered. The Mixed Fuzzy Relation Inequality (MFRI) system is an importance extension of FRI. It is shown that its feasible domain is nonconvex ... 
On the partial sums of convex harmonic univalent functions
(Işık University Press, 20170620)Partial sums of analytic univalent functions and partial sums of starlike have been investigated extensively by several researchers. In this paper, we investigate a partial sums of convex harmonic functions that are univalent ... 
Modulational instability of three dimensional waves in a plasma with vortex electron distribution
(Işık University Press, 20190210)In the present work, employing the three dimensional equations of a plasma composed of a cold electron fluid, hot electrons obeying a trapped / vortexlike distribution, and stationary ions, we study the amplitude modulation ...
