Optimal control and bifurcation diagram for a model nonlinear fractional SIRC [PDF]

Alexandria Engineering Journal, 2020
In this article, the optimal control for nonlinear SIRC model is studied in fractional order using the Caputo fractional derivative. Graph signal flow is given of the model and simulated by Simulink/Matlab which helps in discussing the topological ...

A Study on Blending-Type Approximation Through α-Szász–Durrmeyer-Type Operators

Journal of Taibah University for Science
We propose a Durrmeyer-type extension of the [Formula: see text]-Szász-Mirakyan operators. By employing a unified approach based on the Lipschitz kind maximal function, weighted function spaces, and the Ditzian–Totik modulus of smoothness, we obtain ...

On the order of approximation by modified summation-integral-type operators based on two parameters

Demonstratio Mathematica, 2023
In this article, we the study generalized family of positive linear operators based on two parameters, which are a broad family of many well-known linear positive operators, e.g., Baskakov-Durrmeyer, Baskakov-Szász, Szász-Beta, Lupaş-Beta, Lupaş-Szász ...

On approximation of functions and their derivatives by quasi‐Hermite interpolation

International Journal of Mathematics and Mathematical Sciences, Volume 19, Issue 2, Page 279-286, 1996., 1994
In this paper, we consider the simultaneous approximation of the derivatives of the functions by the corresponding derivatives of quasi‐Hermite interpolation based on the zeros of (1 − x2)pn(x) (where pn(x)is a Legendre polynomial). The corresponding approximation degrees are given. It is shown that this matrix of nodes is almost optimal.

Dunkl analogue of Szász-mirakjan operators of blending type

Open Mathematics, 2018
In the present work, we construct a Dunkl generalization of the modified Szász-Mirakjan operators of integral form defined by Pǎltanea [1]. We study the approximation properties of these operators including weighted Korovkin theorem, the rate of ...

On some constants in simultaneous approximation

International Journal of Mathematics and Mathematical Sciences, Volume 18, Issue 2, Page 279-286, 1995., 1994
Pointwise estimates for the error which is feasible in simultaneous approximation of a function and its derivatives by an algebraic polynomial were originally pursued from theoretical motivations, which did not immediately require the estimation of the constants in such results.
