Analysis of finite element approximations of stokes equations with nonsmooth data
(Society for Industrial and Applied Mathematics, 2020-11-12)
In this paper we analyze the finite element approximation of the Stokes equations with nonsmooth Dirichlet boundary data. To define the discrete solution, we first approximate the boundary datum by a smooth one and then ...
A Posteriori Error Analysis of Two-Step Backward Differentiation Formula Finite Element Approximation for Parabolic Interface Problems
(SPRINGER/PLENUM PUBLISHERS, 2016)
This paper studies a residual-based a posteriori error estimates for linear parabolic interface problems in a bounded convex polygonal domain in . We use the standard linear finite element spaces in space which are allowed ...
Error propagation in open respirometric assays
(Brazilian Society of Chemical Engineering, 2014-04)
This work deals with the calculation of the uncertainty of the exogenous respiration rate (Rex) and the total oxygen consumed (OCT) derived from a single open respirometric profile. Uncertainties were evaluated by applying ...
Adjustment of the hazen-willians equation for determination of continuous pressure drop in PVC pipeAjuste da equação de hazen-willians para determinação da perda de carga contínua em tubulações de PVC
(2019-01-01)
The head loss is a fundamental parameter for the dimensioning of the pipes, being directly related to the cost of these pipes, the selection of the pumping system and the energy cost of electricity. That study fitted the ...
Estimativa de evapotranspiração de referência na região de Rio Paranaíba-MG
(2015-10-01)
The water depth to be applied is a factor of utmost importance for the success of irrigated crops. The objective of this study was to evaluate the correlation of ETo estimate methods proposed by Hargreaves and Samani, ...
