14. Controle robusto de sistemas de potência multimáquinas através de desigualdades matriciais lineares: abordagem por alocação de pólos e ajuste de estabilizadores de sistemas de potência. / Robust control of multimachine power systems through linear matrix inequalities: the pole placement approach with power system stabilizers adjustment.
The aim of this work is to elaborate robust control algorithms to power systems. The mathematical model employed to describe the multimachine power system is that used in small signal studies, and the main goal is to increase the damping of the critical eigenvalues of the system, guaranteeing its stability and performance in various operating conditions.

15. As garantias nos contratos de parcerias público-privadas (PPP) no Brasil
In the past decades, the Brazilian State has been unable to supply, by its own means, the social and economic needs of society. In recent times, it has been trying to attract the private sector in order to collaborate with it in vital areas of society. Based on this current trend, this study aims to analyze the guarantees on the contracts of Public-Private P

17. Influence of an odd structure in cross ply tires. / Influência da estrutura ímpar em pneus de lonas cruzadas (cross-ply).
The tire is the only bond between the vehicle and the ground, is it that transmits all the power and load, and guarantees the driven and conduction of the automobile. The resistant structure of a tire is one of the most important factors for the efficiency, type of application and security. Knowing these parameters is the primary condition to design a tire.

20. Power system state estimation: computer program for analysis and updating of measurement set qualitative characteristics / Estimação de estado em sistemas elétricos de potência: programa para análise e atualização das características qualitativas de conjunto de medidas
To obtain a safe power system (PS) operation, becomes necessary a reliable state estimation (SE), since the real time control actions of a PS are based on the data obtained through the SE process. The first requirement for a successful SE process is the existence of a reliable measurement placement plan, that is, a measurement placement plan that guarantees

21. Viabilidade da utilização de aditivos na ensilagem de capim-braquiarão (Brachiaria brizantha (Hochst ex A. Rich.) Stapf cv. Marandu), manejado sob intensidades de pastejo / Viability on the addictives utilization in braquiarão grass [Brachiaria brizantha (Hochst ex A. Rich.) cv. Marandu] silage process, managed under grazing intensities
Silage is a grassing food conserved by a fermentative process specialy used during scarcity period (dry season). It aims to conserve a high nutritional value with a minimum of losses. In order to assure its produced forage utilization efficiency, it needs to considerate its harvest by animals and machines in a system that uses rotational stocking method. In
