Experimental comparative study on vortex-induced motion (VIM) of a monocolumn platform
(ASME-AMER SOC MECHANICAL ENGNEW YORK, 2012)
An analysis methodology is presented as well as a comparison of results obtained from vortex-induced motion (VIM) model tests of the MonoGoM platform, a monocolumn floating unit designed for the Gulf of Mexico. The choice ...
Analysis Methodology for Vortex-Induced Motion (VIM) of a Monocolumn Platform Applying the Hilbert-Huang Transform Method
(ASME-AMER SOC MECHANICAL ENGNEW YORK, 2012)
Vortex-induced motion (VIM) is a highly nonlinear dynamic phenomenon. Usual spectral analysis methods, using the Fourier transform, rely on the hypotheses of linear and stationary dynamics. A method to treat nonstationary ...
Vortex interaction, chaos and quantum, probabilities
(Europhysics Letters, 2006-12)
The motion of a single vortex is able to originate chaos in the quantum trajectories defined in Bohm's interpretation of quantum mechanics. In this letter, we show that this is also the case in the general situation, in ...
Non-Gaussian tail in the force distribution: a hallmark of correlated disorder in the host media of elastic objects
(Nature, 2020-11)
Inferring the nature of disorder in the media where elastic objects are nucleated is of crucial importance for many applications but remains a challenging basic-science problem. Here we propose a method to discern whether ...
Hyperuniform vortex patterns at the surface of type-II superconductors
(American Physical Society, 2019-10)
A many-particle system must possess long-range interactions in order to be hyperuniform at thermal equilibrium. Hydrodynamic arguments and numerical simulations show, nevertheless, that a three-dimensional elastic-line ...
Regimes of near-wall vortex dynamics in potential flow through gaps
(2010)
In this chapter we propose the design of a discrete-time neural observer which requires no prior knowledge of the model of an anaerobic process, for estimate biomass, substrate and inorganic carbon which are variables ...
Stability of supercurrents in a BiSrCaCuO (Bi-2212) high- Tcsuperconductor with artificially

Cálculo de carregamento aerodinâmico em pá de gerador eólico empregando Vortex Lattice Method
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2017-11-30)
In order to make it possible to use micro wind generators, it is appropriate to passively control the pitch angle. To make this control using composite materials through aeroelastic tailoring it is necessary to know the ...
