Analysis of the stability and dispersion for a Riemannian acoustic wave equation
(ELSEVIER SCIENCE INC, 2019-01-15)
The construction of images of the Earth's interior using methods as reverse time migration (RTM) or full wave inversion (FWI) strongly depends on the numerical solution of the wave equation. A mathematical expression of ...
Numeric simulation of pollutant dispersion by a control-volume based on finite element method
(Wiley-Blackwell, 2011-07-30)
The dispersion of pollutants in the environment is an issue of great interest as it directly affects air quality, mainly in large cities. Experimental and numerical tools have been used to predict the behavior of pollutant ...
Bias-corrected estimators for dispersion models with dispersion covariates
(ELSEVIER SCIENCE BV, 2011)
In this paper we discuss bias-corrected estimators for the regression and the dispersion parameters in an extended class of dispersion models (Jorgensen, 1997b). This class extends the regular dispersion models by letting ...
Coarse-grid higher order finite-difference time-domain algorithm with low dispersion errors
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Higher order (2,4) FDTD schemes used for numerical solutions of Maxwell`s equations are focused on diminishing the truncation errors caused by the Taylor series expansion of the spatial derivatives. These schemes use a ...

Numerical prediction of gas concentrations and fluctuations above a triangular hill within a turbulent boundary layer
(ELSEVIER SCIENCE BV, 2010)
The objective of the present work is to propose a numerical and statistical approach, using computational fluid dynamics, for the study of the atmospheric pollutant dispersion. Modifications in the standard k-epsilon ...
