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 ...

The Zero-Removing Property and Lagrange-Type Interpolation Series [PDF]

open access: yes, 2011
The classical Kramer sampling theorem, which provides a method for obtaining orthogonal sampling formulas, can be formulated in a more general nonorthogonal setting.

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.

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

A Kernel-Independent Treecode Based on Barycentric Lagrange Interpolation [PDF]

open access: yesCommunications in Computational Physics, 2019
A kernel-independent treecode (KITC) is presented for fast summation of pairwise particle interactions. In general, treecodes replace the particle-particle interactions by particle-cluster interactions, and here we utilize barycentric Lagrange ...

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.
