1. Normal form in stability analysis of the L4 point of photogravitational problem / Formas normais no estudo da estabilidade para L4 no problema fotogravitacional
The study of the stability of L4 point of in the photogravitational problem is accomplished. Firstly a normalization algorithm for 2 and 3 degree freedom is accomplished. The equations of motion are written in an extended canonical and then, using the Hori-Lie, method put in a normal form. The stability of the system is analyzed by the theorem of Kovalev and

2. Instability of Equilibrium Points of Some Lagrangian Systems / Instabilidade de pontos de equilíbrio de alguns sistemas lagrangeanos
Neste trabalho, estudamos algumas inversões parciais do teorema de Dirichlet-Lagrange, essencialmente estendendo os resultados em dois graus de liberdade de Garcia e Tal (2003) para algumas situações em $R^$. Mais precisamente, um dos objetivos é mostrar, no contexto da mecânica lagrangeana, que se há um split da energia potencial em uma parte no plano

3. Otimização de estruturas reticuladas planas com comportamento geometricamente não linear / Optimization of plane frame structures with behavior geometrically nonlinear
The aim of this work is to present a formulation and corresponding computational implementation for sizing optimization of plane frames and cable-stayed columns considering geometric non liner behavior. The structural analysis is based on the finite element method using the updated lagrangian approach for plane frame and cable elements, which are represented

4. Orbital maneuvers between the Lagrangian points and the primaries in the Earth-Sun system
This paper is concerned with trajectories to transfer a spacecraft between the Lagrangian points of the Sun-Earth system and the primaries. The Lagrangian points have important applications in astronautics, since they are equilibrium points of the equation of motion and very good candidates to locate a satellite or a space station. The planar circular restri
