Análise do efeito da discretização do modelo de velocidades nas migrações Kirchhoff e Kirchhoff-Gaussian- Beam 2D pré-empilhamento em profundidade
(Universidade Federal do ParáBrasilInstituto de GeociênciasUFPAPrograma de Pós-Graduação em Geofísica, 2014)
Spline-based methods with adaptive refinement for problems of acoustics and fracture mechanics of thin plates
(Universidad de Chile, 2018)
Both the CAD software and FEM software have a significant impact on engineering nowadays. Even though both are powerful tools for design and analysis, the main drawback is that CAD geometries and Finite Element models do ...
Exponential stability of a mildly dissipative viscoelastic plate equation with variable density
(2019-01-30)
This paper is concerned with a viscoelastic Kirchhoff plate featuring variable material density. It is modeled by the equation (Formula presented.) defined in a bounded domain of R N , where ϱ = |u t | ρ accounts for a ...
Wave equation datuming to correct topography effect on foothill seismic data
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2005)
The current seismic processing applies Static Corrections to overcome the effects associated to rough topography, based in the assumption that velocity in near surface is lower than in the substratum, which force going up ...
