A numerical scheme for advection dominated problems based on a Lagrange interpolation

, 2021
Applying conventional numerical techniques for solving advection dominated problems, especially in the presence of sharp gradients, produces inaccurate results. This paper presents a robust numerical scheme for approximating the advection equation.

Investigation of entropy generation in a square inclined cavity using control volume finite element method with aided quadratic Lagrange interpolation functions

International Communications in Heat and Mass Transfer, 2020
One of the most concerned subjective in Mechanical science is natural convection study in a cavity. Furthermore, the investigation of entropy generation can be useful for better designing of the thermal systems.

Boolesche zweidimensionale Lagrange-Interpolation

Computing, 1979
Die vorliegende Arbeit liefert eine systematische Anwendung der von Gordon [4], [5] entwickelten Methode der Booleschen Approximation von Funktionen mehrerer Veranderlicher in der zweidimensionalen Lagrange-Interpolation. Es werden Interpolationsmethoden untersucht, deren Interpolationsprojektoren sich als K-fache (K ∈ ℕ) Boolesche Summe von ...

A Kind of Lagrange Interpolation on the Sphere

2009 WRI World Congress on Computer Science and Information Engineering, 2009
In this paper we deeply research Lagrange interpolation on the unit sphere. First we study the Lagrange interpolation problem along a set of latitudes on the sphere and give three kinds of properly posed sets of nodes along it. Then we get a class of properly posed set of nodes for Lagrange interpolation on the unit sphere by superposition ...

Neural network interpolation operators optimized by Lagrange polynomial

Neural Networks, 2022
In this paper, we introduce a new type of interpolation operators by using Lagrange polynomials of degree r, which can be regarded as feedforward neural networks with four layers.

New Results on Lagrange Interpolation

1992
Uniform convergence of Lagrange interpolation at zeros of Jacobi polynomials or at the zeros of product Jacobi polynomials, as well as at the zeros of generalized smooth Jacobi polynomials is investigated. We show that by a simple procedure it is always possible to transform the matrices of these zeros into matrices such that the corresponding Lagrange

A steady barycentric Lagrange interpolation method for the 2D higher‐order time‐fractional telegraph equation with nonlocal boundary condition with error analysis

Numerical Methods for Partial Differential Equations, 2019
In this paper, we consider the numerical solution of the time‐fractional telegraph equation with a nonlocal boundary condition. A novel barycentric Lagrange interpolation collocation method is developed to solve this equation.

Hybrid Lagrange interpolation differential evolution algorithm for path synthesis

Mechanism and Machine Theory, 2019
A hybrid Lagrange interpolation differential evolution algorithm (HLIDE) is proposed in this study for path synthesis of four-bar mechanisms. HLIDE combines two algorithms of differential evolution (DE) with Lagrange interpolation local search (LILS ...
