1. Orbitas periodicas em sistemas mecanicos / Periodic orbits in dynamical systems
In this work we study dynamical systems possessing Hamiltonian and time-reversible structures. The reversibility concept is de¯ned in terms of an involution. Initially we discuss the dynamics of Hamiltonian vector ¯elds with 2 and 3 degrees of freedom around an elliptic equilibrium in the presence of an involution which preserves the symplectic structure.

2. Um modelo de espaço de estados com representação de segunda ordem para a analise das oscilações de modo interarea em sistemas de energia eletrica / A space state model including second order representation for the analysis of power systems inter-area mode oscillations
In this work, the analysis of power systems inter-area mode oscillations is performed by the application of two different methodologies: first, the linear modal analysis, and then the analysis including second order nonlinear terms from a Taylor series expansion, with the application of the method of normal forms of vector fields. In this case, the method of
