Analysis of wave scattering from non-symmetric discontinuities in one-dimensional wave-guides
(2017-01-01)
Predicting the scattering from waves that are incident on a damaged section of structure is of importance in structural health monitoring and nondestructive testing techniques to detect dam-age. High frequency waves are ...
Importance of event detection and nonlinear characterization of dynamical systems with discontinuity boundary
(2021-01-01)
In this study, the response of a dynamical system with an increasingly stiff freeplay nonlinearity is investigated. Numerical simulations are carried out on a forced Duffing oscillator with low, intermediate, and hard ...
Robust traffic density estimation using discontinuous Galerkin formulation of a macroscopic model
(IEEE, 2015)
In this paper, we develop a data-assimilation algorithm for a macroscopic model of traffic flow. The algorithm is based on the Discontinuous Galerkin Method and Minimax Estimation, and is applied to a macroscopic model ...
Shock Capturing Using Interpolatory Wavelets

Simulación de bandas de corte en materiales granulares empleando discontinuidades débiles en un modelo constitutivo hipoplástico
(Universidad de La Salle. Ediciones Unisalle, 10 d)
Coupling Finite Elements for Modelling Fluid Flow in Fractured Porous Media
(2020-01-01)
The presence of discontinuities such as cracks and faults in porous media can remarkably impact the fluid pressure distribution. This is due to considerable contrast between hydraulic properties of porous matrix and ...
Desarrollos en mecánica computacional de falla material. Aplicación a modelos de plasticidad y daño
(2011-10-18)
In this research work, finite element (FE) formulations for the numerical simulation of strain localization phenomenon are studied and developed, including some efficient strategies devised to modeling discontinuities in ...
Exploring various flux vector splittings for the magneto hydrodynamic system
(Elsevier, 2016)
In this paper we explore flux vector splittings for the MHD system of equations. Our approach follows the strategy that was initially put forward in Toro and Vazquez-Cendon (2012) [55]. We split the flux vector into an ...
Origin and sustainability of the population of asteroids captured in the exterior resonance 1:2 with Mars
(Elsevier, 2011-08)
At present, approximately 1500 asteroids are known to evolve inside or sticked to the exterior 1:2 resonance with Mars at a ≃ 2.418 AU, being (142) Polana the largest member of this group. The effect of the forced secular ...
Intraspecific variation in the venom electrophoretic profile of recently captured Crotalus durissus terrificus (Laurenti, 1768) snakes
(Centro de Estudos de Venenos e Animais Peçonhentos - CEVAP, Universidade Estadual Paulista - UNESP, 2001-12)
The aim of this study was to compare individual venom samples of Crotalus durissus terrificus recently captured in the wild to evaluate possible differences in venom protein composition. Protein levels were quantified by ...
