Generalized Jacobian Weighted Modulus of Smoothness

Iraqi Journal of Science, 2023
      The topic of modulus of smoothness still gets the interest of many researchers due to its applicable usage in different fields, especially for function approximation. In this paper, we define a new modulus of smoothness of weighted type. The properties of our modulus are studied.

On Shape Parameter α-Based Approximation Properties and q-Statistical Convergence of Baskakov-Gamma Operators

Journal of Mathematics, 2022
We construct a novel family of summation-integral-type hybrid operators in terms of shape parameter α∈0,1 in this paper. Basic estimates, rate of convergence, and order of approximation are also studied using the Korovkin theorem and the modulus of ...

An analysis of the elastic properties of a porous aluminium oxide film by means of indentation techniques [PDF]

, 2013
The elastic modulus of thin films can be directly determined by instrumented indentation when the indenter penetration does not exceed a fraction of the film thickness, depending on the mechanical properties of both film and substrate.

Some Moduli of Angles in Banach Spaces

Mathematics, 2022
In this paper, we mainly discuss the angle modulus of convexity δXa(ϵ) and the angle modulus of smoothness ρXa(ϵ) in a real normed linear space X, which are closely related to the classical modulus of convexity δX(ϵ) and the modulus of smoothness ρX(ϵ ...

On certain Baskakov-Durrmeyer type operators [PDF]

Surveys in Mathematics and its Applications, 2010
This paper is a study of the degree of approximation by the linear combinations of the derivatives of certain Durrmeyer type integral modification of the Baskakov operators in terms of the higher order modulus of smoothness.

Blending type approximation by Stancu-Kantorovich operators based on Pólya-Eggenberger distribution

Open Physics, 2017
In the paper the authors introduce the Kantorovich variant of Stancu operators based on Pólya-Eggenberger distribution. By making use of this new operator, we obtain some indispensable auxiliary results.

Some Modulus and Normal Structure in Banach Space

Journal of Inequalities and Applications, 2009
We present some sufficient conditions for which a Banach space X has normal structure in terms of the modulus of U-convexity, modulus of W∗-convexity, and the coefficient R(1,X), which generalized some well-known results.
