Numerical methods for elliptic partial differential equations with rapidly oscillating coefficients
(2003)
This paper presents two methods for the numerical solution of the classical homogenization problem of elliptic
operators with periodically oscillating coefficients. The numerical solution of such problems is difficult ...
A Numerical method for the semilinear stochastic transport equation
(EMAp - Escola de Matemática Aplicada, 2015)
We propose a new numerical method for the computer simulation of the semi-linear transport equation. Based on the stochastic characteristic method and the Local Linearization technique, we construct an effi cient and stable ...
Sparse matrices for transient simulations with computing memory reduction
(2020-06-01)
Modified numerical integration methods and modelling have been analysed for application to simulations of electromagnetic transient phenomena in transmission lines. Both objectives are considered: minimize numerical errors ...
An Efficient Galerkin BEM to Compute High Acoustic Eigenfrequencies
(ASME-AMER SOC MECHANICAL ENG, 2009)
An efficient numerical method, using integral equations, is developed to calculate precisely the acoustic eigenfrequencies and their associated eigenvectors, located in a given high frequency interval. It is currently known ...
Adaptive filtering strategy for numerical constraint satisfaction problems

Numerical multiscale methods
(Wiley-Blackwell, 2012-10-10)
We restrict the variational multiscale method to a class of methods we denote by numerical multiscale methods. Numerical multiscale methods are methods obtained by enriching the piecewise linear functions with special local ...
