Vibration analysis of the plate with the regular and irregular domain by using the Barycentric Lagrange interpolation

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2020
This paper uses the Barycentric Lagrange interpolation method to explore the free vibration of a plate with the regular and irregular domain using the Chebyshev function, allowing us to consider multiple dimensions. From our results, it can be shown that

A new interpolation method based on satellite physical character in using IGS precise ephemeris

open access: yesGeodesy and Geodynamics, 2014
Due to the deficiency of sliding Lagrange polynomial interpolation, the author proposes a new interpolation method, which considers the physical character of satellite movement in coordinate transformation and reasonable selection of interpolation ...

Optimal control for a fractional tuberculosis infection model including the impact of diabetes and resistant strains

open access: yesJournal of Advanced Research, 2019
The objective of this paper is to study the optimal control problem for the fractional tuberculosis (TB) infection model including the impact of diabetes and resistant strains. The governed model consists of 14 fractional-order (FO) equations.

A new multiplier for Lagrange interpolation in constrained non linear optimization [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2010
In this paper, we have investigated a new multiplier for the Lagrange interpolation by modifying the initial value of the multiplier in order to reduce the errors and avoid the use of arbitrary values for the initial .

Numerical treatments for a multi-time delay complex order mathematical model of HIV/AIDS and malaria

open access: yesAlexandria Engineering Journal, 2022
In this artical, we present a novel complex order nonlinear mathematical model of HIV/AIDS and Malaria co-infection with multi-delay. The proposed model is formulated as a system of twelve complex order differential equations.

Stieltjes polynomials and Lagrange interpolation [PDF]

open access: yesMathematics of Computation, 1997
Summary: Bounds are proved for the Stieltjes polynomial \(E_{n+1} \), and lower bounds are proved for the distances of consecutive zeros of the Stieltjes polynomials and the Legendre polynomials \(P_n\). This sharpens a known interlacing result of Szegö. As a byproduct, bounds are obtained for the Geronimus polynomials \(G_n\).

Lagrange interpolation on the semiaxis [PDF]

open access: yes, 2012
In this brief survey are collected some recent results about optimal interpolation processes of Lagrange type based on the zeros of generalized Laguerre polynomials, i.e. the sequence of orthogonal polynomials where A new extended Lagrange process having

Boundedness of Lebesgue Constants and Interpolating Faber Bases

open access: yesНаукові вісті Національного технічного університету України "Київський політехнічний інститут", 2017
Background. We investigate the relationship between the boundedness of Lebesgue constants for the Lagrange polynomial interpolation on a compact subset of \[\mathbb R\] and the existence of a Faber basis in the space of continuous functions on this ...

Function correction and Lagrange – Jacobi type interpolation [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2023
It is well-known that the Lagrange interpolation based on the Chebyshev nodes may be divergent everywhere (for arbitrary nodes, almost everywhere), like the Fourier series of a summable function.
