Aplicação de elementos finitos de acoplamento para a modelagem explícita dos efeitos de fraturas naturais em análises de fluxo em meios porosos saturados
(Universidade Estadual Paulista (Unesp), 2021-04-21)
Os diferentes níveis de escalas entre o reservatório (matriz porosa) e as fraturas (ou mesmo feições cársticas) constituem um problema bastante desafiador à indústria do petróleo. Com base nisso, este trabalho apresenta ...
Conservative interpolation on surface interfaces for transport problems in the Finite Volume Method
(Academic Press Inc Elsevier Science, 2019-10)
This paper presents a new strategy to couple non-matching interfaces in the Finite Volume Method based on a conservative interpolation. In contrast to most of the conservative methods, the current approach does not modify ...
Design of SPR systems with dynamic compensators and output variable structure control
(2006-12-22)
This paper presents necessary and sufficient conditions for the following problem: given a linear time invariant plant G(s) = N(s)D(s)-1 = C(sI - A]-1B, with m inputs, p outputs, p > m, rank(C) = p, rank(B) = rank(CB) = ...

Heart failure alters matrix metalloproteinase gene expression and activity in rat skeletal muscle
(Blackwell Publishing, 2006-12-01)
Heart failure is associated with a skeletal muscle myopathy with cellular and extracellular alterations. The hypothesis of this investigation is that extracellular changes may be associated with enhanced mRNA expression ...
