On groups with cubic polynomial conditions
(2015-09-01)
Let F<inf>d</inf> be the free group of rank d, freely generated by {y1,. . .,yd}, and let DFd be the group ring over an integral domain D. Given a subset E<inf>d</inf> of F<inf>d</inf> containing the generating set, assign ...
Bubble annular photoeletrocatalytic reactor with TiO<inf>2</inf> nanotubes arrays applied in the textile wastewater
(2015-06-01)
This study proposed a simple and effective annular bubble photoreactor using an array of TiO<inf>2</inf> nanotubes (NTs) prepared in situ by an anodisation process and used as photoanodes. The method is based on ...
Período de formação do cacho e biorreguladores na produção e qualidade da banana ‘Grande Naine
(2015-01-01)
The objectives of this study were to determine the effect of climatic conditions during the period of bunch formation and growth regulators on yield and quality of banana ‘Grande Naine’. The experiment was conducted in a ...
Mixed spectral/hp element formulation for nonlinear elasticity

An adaptive Uzawa FEM for the Stokes problem: Convergence without the inf-sup condition
(Society for Industrial and Applied Mathematics, 2002-09)
We introduce and study an adaptive finite element method (FEM) for the Stokes system based on an Uzawa outer iteration to update the pressure and an elliptic adaptive inner iteration for velocity. We show linear convergence ...
Numerical assessment of stability of interface discontinuous finite element pressure spaces
(ElsevierLausanne, 2012)
The stability of two recently developed pressure spaces has been assessed numerically: The space proposed by Ausas et al. [R.F. Ausas, F.S. Sousa, G.C. Buscaglia, An improved finite element space for discontinuous pressures, ...
