Influence of structural nonlinearities in stall-induced aeroelastic response of pitching airfoils
(European Assoc Structural Dynamics, 2014-01-01)
Stall-induced vibrations are a relevant aeroelastic problem for very flexible aero-structures. Helicopter blades, wind turbines, or other rotating components are severely inflicted to vibrate in stall condition during each ...

Modelo matemático para o sistema oscilante de glicina catalisado pelo complexo NiL(ClO4)2
(Universidade Tecnológica Federal do ParanáLondrinaBrasilLicenciatura em QuímicaUTFPR, 2019-12-11)
In 2010, an oscillating system was reported that constitutes a variant of the Belousov-Zhabotinskii reaction (BZ), in which the organic substrate are both the amino acid glycine and acetone, catalyzed by a nickel II ...
A gallery of oscillations in a resonant electric circuit: Hopf-Hopf and fold-flip interactions
(World Scientific, 2008-12)
In this work, the dynamics of a coupled electric circuit is studied. Several bifurcation diagrams associated with the truncated normal form of the Hopf-Hopf bifurcation are presented. The bifurcation curves are obtained ...
Reações químicas e equações de Lienard generalizadas
(Universidade Federal de Minas GeraisUFMG, 2015-07-20)
On this work are presented two models of chemistry reactions and here we show how to write differential equations for the concentrations of chemistry species involved on the reaction. The first model consists of the ...
Medidas da concentração de oxigênio dissolvido na superfície da água
(ABES, 2008)
A transferência de gases através da interface ar-água é um processo importante para ciclos climáticos de grande escala e para sistemas ambientais menores como rios, lagos, córregos e estações de tratamento de esgoto. Para ...
