Nogueira T, Pereira F, Procopio J, Sartorelli J
Chaos . 2018 Dec; 28(11):113101. PMID: 30501219
Two experimental bifurcation diagrams were obtained with two different control parameters. One parameter was the faucet opening and the other one, keeping fixed the faucet opening, was an electrical voltage...

Depetri G, Pereira F, Marin B, Baptista M, Sartorelli J
Chaos . 2018 Apr; 28(3):033103. PMID: 29604657
The dynamics of a parametric simple pendulum submitted to an arbitrary angle of excitation ϕ was investigated experimentally by simulations and analytically. Analytical calculations for the loci of saddle-node bifurcations...

Depetri G, Sartorelli J, Marin B, Baptista M
Phys Rev E . 2016 Aug; 94(1-1):012202. PMID: 27575118
Our aim is to unveil how resonances of parametric systems are affected when symmetry is broken. We showed numerically and experimentally that odd resonances indeed come about when the pendulum...

Chaos . 2010 Jan; 19(4):043115. PMID: 20059211
We show a function that fits well the probability density of return times between two consecutive visits of a chaotic trajectory to finite size regions in phase space. It deviates...

Nogueira T, Sartorelli J, Pato M, Ellegaard C
Phys Rev E Stat Nonlin Soft Matter Phys . 2008 Dec; 78(5 Pt 2):055201. PMID: 19113176
It is shown that the deviations of the experimental statistics of six chaotic acoustic resonators from Wigner-Dyson random matrix theory predictions are explained by a recent model of random missing...

Maranhao D, Baptista M, Sartorelli J, Caldas I
Phys Rev E Stat Nonlin Soft Matter Phys . 2008 Jun; 77(3 Pt 2):037202. PMID: 18517562
The existence of a special periodic window in the two-dimensional parameter space of an experimental Chua's circuit is reported. One of the main reasons that makes such a window special...

Pereira T, Baptista M, Reyes M, Caldas I, Sartorelli J, Kurths J
Phys Rev E Stat Nonlin Soft Matter Phys . 2006 Feb; 73(1 Pt 2):017201. PMID: 16486314
We show experimentally the scenario of a two-frequency torus T2 breakdown, in which a global bifurcation occurs due to the collision of a torus with an unstable periodic orbit, creating...

Pato M, Schaadt K, Tufaile A, Ellegaard C, Nogueira T, Sartorelli J
Phys Rev E Stat Nonlin Soft Matter Phys . 2005 May; 71(3 Pt 2B):037201. PMID: 15903638
We applied a recently proposed rescaling of curvatures of eigenvalues of parameter-dependent random matrices to experimental data from acoustic systems and to a theoretical result. It is found that the...

Phys Rev E Stat Nonlin Soft Matter Phys . 2003 Jan; 66(5 Pt 2):056204. PMID: 12513583
We studied the formation dynamics of air bubbles emitted from a nozzle submerged in aqueous glycerol solutions of different viscosities. We describe the evolution of the bubbling regimes by using...
