Approximation of functions of two variables by certain linear positive operators

, 2007
We introduce certain linear positive operators and study some approximation properties of these operators in the space of functions, continuous on a compact set, of two variables.

A Baskakov-Kantorovich operators reproducing affine functions: inverse results

Journal of Numerical Analysis and Approximation Theory, 2022
In a previous paper the author presented a Kantorovich modification of Baskakov operators which reproduce affine functions and he provided an upper estimate for the rate of convergence in polynomial weighted spaces.

Sampling and Reconstruction of Signals in a Reproducing Kernel Subspace of $L^p({\Bbb R}^d)$

, 2009
In this paper, we consider sampling and reconstruction of signals in a reproducing kernel subspace of $L^p(\Rd), 1\le p\le \infty$, associated with an idempotent integral operator whose kernel has certain off-diagonal decay and regularity.

(p,q)-Generalization of Szasz-Mirakyan Operators

, 2015
In this paper, we introduce new modifications of Szasz-Mirakyan operators based on (p,q)-integers. We first give a recurrence relation for the moments of new operators and present explicit formula for the moments and central moments up to order 4.

An experimental flow regime map to dynamically structure gas–solid bubbling fluidized beds

AIChE Journal, Volume 71, Issue 5, May 2025.
Abstract Employing oscillatory gas flows to create ordered bubble dynamics in fluidized beds represents a promising approach in reactor design, enhancing efficiency, scalability, and control. This study reports an extensive experimental campaign that identifies the operational regime for structuring Geldart B fluidized beds, introducing a novel pattern

Approximation properties of q-Baskakov operators

Open Mathematics, 2010
Abstract We establish direct estimates for the q-Baskakov operator introduced by Aral and Gupta in [2], using the second order Ditzian-Totik modulus of smoothness. Furthermore, we define and study the limit q-Baskakov operator.

Characteristics and outcomes of older patients undergoing out‐ versus inpatient surgery in Europe. A secondary analysis of the Peri‐interventional Outcome Study in the Elderly (POSE)

Acta Anaesthesiologica Scandinavica, Volume 69, Issue 4, April 2025.
Abstract Background The number of older patients undergoing surgical procedures with anaesthesia care is projected to rise. In order to cope with the increased demand, the expansion of outpatient surgery may play a decisive role. We aim to investigate the characteristics and outcomes of the older outpatient population.

Curves defined by a class of discrete operators: Approximation result and applications

Mathematical Methods in the Applied Sciences, Volume 48, Issue 2, Page 2388-2403, 30 January 2025.
In approximation theory, classical discrete operators, like generalized sampling, Szász‐Mirak'jan, Baskakov, and Bernstein operators, have been extensively studied for scalar functions. In this paper, we look at the approximation of curves by a class of discrete operators, and we exhibit graphical examples concerning several cases. The topic has useful

Lp-inverse theorem for modified beta operators

International Journal of Mathematics and Mathematical Sciences, 2003
We obtain a converse theorem for the linear combinations of modified beta operators whose weight function is the Baskakov operators. To prove our inverse theorem, we use the technique of linear approximating method, namely, Steklov mean.
