In this paper, a new extrapolation economy cascadic multigrid method is proposed to solve the image restoration model. The new method combines the new extrapolation formula and quadratic interpolation ...

Abstract: To model the responses of borehole electromagnetic sensing in complicated geological environments, the geometric multigrid preconditioned finite-difference frequency-domain (FDFD) method is ...

This paper proposes a new method for data assimilation of the surface radial current observed by High Frequency ground wave radar and optimization of the bottom friction coefficient. In this method, ...

In contrast to the standard algebraic multigrid, the Wavelet-based Algebraic Multigrid method relies more strongly on the smoothing method because the coarse spaces are chosen a priori. So, it is very ...

Numerically solving linear partial differential equations such as the Poisson equation or the Helmholtz equation. Equation (1): An equation with a linear operator $$\mathcal{L}$$. The Poisson equation ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

The repository contains examples and programs from the book “Parallel Software for the Robust Multigrid Technique” by S. I. Martynenko, Triumph, Moscow, 2021. Complete text of the book in Russian is ...

This project was part of the course ID5130 Parallel Scientific Computing taken during the Jan-May 2024 semester. The main objective of this work is to parallelize the multigrid method using OpenMP for ...

Simulating the behavior of clothing and other fabrics in animated films requires animators to make tradeoffs between a realistic look and a reasonable amount of computing time. Researchers at Walt ...
