13. Topological studies of periodic orbits in the experimental Chua s circuit / Estudo topológico de órbitas periódicas no circuito experimental de Chua
We have studied the dynamical behavior of experimental time series obtained from a Chua s circuit by variation of two parameter control, $Delta R_1$ and $Delta R_2$. We investigated the chaotic and periodic behaviors of the circuit, analyzing temporal series around and inside of two periodic windows in the two-parameter space $(Delta R_1,Delta R_2)$. In the

14. Evolution of chaos in the Matsumoto-Chua circuit: a symbolic dynamics approach
We use symbolic dynamics to follow the evolution of the Matsumoto-Chua circuit in the chaotic regime. We consider the evolution of the whole population of unstable periodic orbits and of the associated trajectories, in four chaotic attractors generated by the circuit. Symbolic planes and first return maps are built for different values of the control paramet

15. Dinamica e controle não lineares de um sistema neuronal ideal e nã-ideal / No-linear dynamics and control of an ideal and non-ideal neural system
In this work it is studied the plasmatic membrane behavior through an electric circuit. The electric model was developed by Hodgkin and Huxley at 1952 and it treats of the variation of the amount of time related with the potassium and sodium conductance s in the squid axon, this model has served as an archetype for mannering mathematical model of eletrophysi

16. Turismo e urbanizaÃÃo: gestÃo de impactos no litoral de Aquiraz-CE. / Tourism and urbanization: management of impacts in the coast of Aquiraz-CE.
The present study retakes the conflicts generated by touristic activities before the lack of instruments of urban and environmental control which, to a large extent, brings about a large number of impacts occasioned by a chaotic occupancy of seashore areas. Comprising two distinct parts, the study starts out from a theoretical approach towards reinterpreting

17. Dinamica não linear e interações de defeitos topologicos e solitons na presença de forças externas e impurezas
We study the catastrophes that can occur in kink dynamics in the presence of external forces and impurities. Under the action of some anharmonic forces it can occurs that not only the translational mode is unstable but also the internal modes ( shape modes) or even part of the continuum spectrum ( the soliton is unstable against the interaction with phonons!

18. Controlling system dimension: A class of real systems that obey the Kaplan–Yorke conjecture
The Kaplan–Yorke conjecture suggests a simple relationship between the fractal dimension of a system and its Lyapunov spectrum. This relationship has important consequences in the broad field of nonlinear dynamics where dimension and Lyapunov exponents are frequently used descriptors of system dynamics. We develop an experimental system with controllable d
