A time domain harmonic BEM implementation for non-homogeneous 3D solids
(Elsevier Sci LtdOxfordInglaterra, 2006)
A note on the controllability for the wave equation in nonsmooth plane domains
(Elsevier B.V., 2006-01-01)
We study exact boundary controllability for a two-dimensional wave equation in a region which is an angular sector of a circle or an angular sector of an annular region. The control, of Neumann type, acts on the curved ...

Utilizando o metódo das características para resolver uma equação diferencial parcial hiperbólica
(Universidade Tecnológica Federal do ParanáCampo MouraoPrograma de Pós-Graduação em Matemática, 2013)
Depth study of the Wave Equation where there was a concern with the deduction of the wave equation for longitudinal vibrations with a dimension, bringing his detailed demonstration by Newton’s Second Law, applying the ...
Bloch wave homogenization and spectral asymptotic analysis
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 1998-02)
We consider a second-order elliptic equation in a bounded periodic heterogeneous medium and study the asymptotic behavior of its spectrum, as the structure period goes to zero. We use a new method of Bloch wave homogenization ...
Surface gravity waves on randomly irregular floor and the telegrapher's equation
(American Institute of Physics, 2021-04)
The simplest model for the evolution of the mean-value of a surface gravity wave propagating in a random bottom has been connected with the telegrapher's equation. This analysis is based on the comparison of the mean-value ...

On the extended applications of Homogenous Balance Method
(Elsevier B.V., 2001-10-15)
In this paper, we study the travelling wave reductions for certain (2 + 1)- and (3 + 1)-dimensional physically important nonlinear evolutionary equations by using the recently proposed Homogenous Balance Method (HBM). ...
