In this study, motivating our earlier work [O. Duman and M.A. Ozarslan, Szasz-Mirakjan type operators providing a better error estimation. Appl. Math. Lett. 20, 1184--1188 (2007)], we investigate the local approximation ...
The moments for q-Bernstein operators in the case 0 < q < 1

Mahmudov, Nazim I. (Springer US, 2010)

In this note we give the estimates of the central moments for q-Bernstein operators (0 < q < 1) which can be used for studying the approximation properties of the operators.
New families of generating functions for certain class of three-variable polynomials

Özarslan, Mehmet Ali; Kaanoğlu, Cem (Elsevier ınc, 2011)

Recently, Srivastava, Özarslan and Kaanoglu have introduced certain families of three and two variable polynomials, which include Lagrange and Lagrange-Hermite polynomials, and obtained families of two-sided linear generating ...
New Korovkin Type Theorem for Non-Tensor Meyer–König and Zeller Operators

Özarslan, Mehmet Ali (Springer International Publishing, 2016)

In this paper, we introduce a certain class of linear positive operators via a generating function, which includes the non-tensor MKZ operators and their non-trivial extension. In investigating the approximation properties, ...
New Singular and Nonsingular Colliding Wave Solutions in Einstein-Maxwell-Scalar Theory

Gürtuğ, Özay; Halilsoy, Mustafa; Sakallı, İzzet (Kluwer Academic Publishers-Plenum Publishers, 2003)

A technique is given to generate coupled scalar field solutions in colliding Einstein-Maxwell (EM) waves. By employing the Bell-Szekeres solution as seed and depending on the chosen scalar field, it is possible to construct ...
A Novel Fully Implicit Block Coupled Solution Strategy For The Ultimate Treatment of The Velocity–Pressure Coupling Problem in İncompressible Fluid Flow

Mazhar, Zeka (Taylor & Francis (Routledge), 2016-01-21)

Two new extremely robust, fully implicit coupled solution procedures (FICS-1 and FICS-2) are presented for the ultimate solution of the notorious velocity–pressure coupling problem arising in incompressible fluid flow ...
On a class of generalized q-Bernoulli and q-Euler polynomials

Mahmudov, Nazim I.; Keleshteri, M Eini (Springer International Publishing AG, 2013)

The main purpose of this paper is to introduce and investigate a new class of generalized q-Bernoulli and q-Euler polynomials. The q-analogues of well-known formulas are derived. A generalization of the Srivastava-Pintér ...
On a singular integral equation including a set of multivariate polynomials suggested by Laguerre polynomials

In this paper, we introduce the class of polynomials Zn1,…,nj(α)(x1,…,xj;ρ1,…,ρj) suggested by the multivariate Laguerre polynomials. We give Schläfli’s contour integral representation and calculate the fractional order ...
On asymptotical behavior of solution of Riccati equation arising in linear filtering with shifted noises

Bashirov, Agamirza E.; Mazhar, Zeka (Springer, 2007)

In this paper we consider a linear signal system together with the two linear observation systems. The observation systems differ from each other by the noise processes. The noise of one of them is a constant shift in time ...
On modeling with multiplicative differential equations

Tandoğdu, Yücel; Bashirov, Agamirza; Mısırlı, Emine; Özyapıcı, Ali (SP Editorial Committee of Applied Mathematics - A Journal of Chinese Universities, 2011)

This work is aimed to show that various problems from different fields can be modeled more efficiently using multiplicative calculus, in place of Newtonian calculus. Since multiplicative calculus is still in its infancy, ...

Bashirov, Rza; Karanfiller, Tolgay (Elsevier, 2010)

Although optical multistage interconnection networks (OMINs) promise to meet the ever growing demands of communication networks and multiprocessor systems in fast communication, they suffer from challenges such as path ...
