Characterization in bi-parameter space of a non-ideal oscillator
S. L. T. de Souza, A. M. Batista, M. S. Baptista +2
We investigate the dynamical behavior of a non-ideal Duffing oscillator, a system composed of a mass-spring-pendulum driven by a DC motor with limited power supply. To identify new…
Parameter Uncertainties on the Predictability of Periodicity and Chaos
E. S. Medeiros, I. L. Caldas, M. S. Baptista
Nonlinear dynamical systems, ranging from insect populations to lasers and chemical reactions, might exhibit sensitivity to small perturbations in their control parameters, resulti…
Dynamical estimates of chaotic systems from Poincaré recurrences
Murilo S. Baptista, Dariel M. Maranhao, Jose C. Sartorelli
We show that the probability distribution function that best fits the distribution of return times between two consecutive visits of a chaotic trajectory to finite size regions in…
Experimental observation of a complex periodic window
D. M. Maranhão, M. S. Baptista, J. C. Sartorelli +1
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 sp…
