Abstract multiscale-hybrid-mixed methods
Madureira, Alexandre L.
2015-12In an abstract setting, we investigate the basic ideas behind the Multiscale Hybrid Mixed (MHM) method, a Domain Decomposition scheme designed to solve multiscale partial differential equations (PDEs) in parallel. As ... -
Analysis of the Finite Element Method for the Laplace–Beltrami Equation on Surfaces with Regions of High Curvature Using Graded Meshes
Guzman, Johnny; Madureira, Alexandre L.; Sarkis, Marcus; Walker, Shawn
2017We derive error estimates for the piecewise linear finite element approximation of the Laplace–Beltrami operator on a bounded, orientable, (Formula presented.), surface without boundary on general shape regular meshes. As ... -
COVID-19: análise com um modelo estatístico para dados em painel
Campos, Eduardo Lima; Cysne, Rubens Penha; Madureira, Alexandre L.
2020-07Esse trabalho tem por objetivo oferecer resultados relativos ao impacto de algumas variáveis mencionadas na literatura, sobre a taxa de variação diária de casos (por milhão de habitantes) registrados da COVID-19. Utilizam-se ... -
Hierarchical modeling of heterogeneous plates
Carius, Ana C.; Madureira, Alexandre L.
2015-10The use of asymptotic limits to model heterogeneous plates can be troublesome, because it requires a priori knowledge on the ratio between characteristic lengths of heterogeneities and thickness. Moreover, it also relies ... -
A hybrid-mixed method for elasticity
Harder, Christopher; Madureira, Alexandre L.; Valentin, Frédéric
2016-04This work presents a family of stable finite element methods for two-and three-dimensional linear elasticity models. The weak form posed on the skeleton of the partition is a byproduct of the primal hybridization of the ... -
Multi-generational SIR modeling: Determination of parameters, epidemiological forecasting and age-dependent vaccination policies
Campos, Eduardo Lima; Cysne, Rubens Penha; Madureira, Alexandre L.; Mendes, Gélcio L. Q.
2021We use an age-dependent SIR system of equations to model the evolution of the COVID-19. Parameters that measure the amount of interaction in different locations (home, work, school, other) are approximated from in-sample ... -
The reward-attention circuit model: nicotine's influence on attentional focus and consequences on attention deficit hyperactivity disorder
Guimarães, Karine; Madureira, Daniele Q. M.; Madureira, Alexandre L.
2017-06-14In this work we investigate the influence that nicotine exerts on attention focusing, modeling the coupling of reward and thalamocortical circuits. Each neuron in the neural networks that replicate such circuits is described ... -
Social distancing, temperature, BCG and the evolution of COVID-19: a panel-model analysis
Campos, Eduardo Lima; Cysne, Rubens Penha; Madureira, Alexandre L.
2020-10Background: This work presents results concerning the impact of some variables mentioned in the literature on the daily variation rate of cases (per million inhabitants) of COVID-19, based on a large sample of countries ...
