1. The use of smart structures in the realization of effective semi-active Control systems for vibration reduction
The realization of semi-active actuators by smart structures is discussed. Semi-active actuators have the advantage of consuming much less power than direct-active actuators and are appropriate for the utilization in vibration problems encountered in aeronautical applications, where the loads are in general too high for direct-active actuators to perform.

2. On the effect of the near field records on the steel braced frames equipped with energy dissipating devices
The behavior of braced steel frame structures is of special importance due to its extensive use. Also the application of active and semi-active control systems, regarding to their benefits in obtaining better seismic performance has increased significantly. The majority of the works on steel structures and steel connections has been done under far field reco

3. Controle robusto de suspensão semi-ativa para caminhonetes utilizando amortecedores magneto-reológicos. / Robust control of a semi-active pickup truck suspension using magneto-rheological dampers.
A utilização de sistemas semi-ativos no controle de movimento e vibração vem crescendo muito nos últimos anos, e está se firmando como a opção mais econômica em muitas aplicações. Os sistemas de controle semi-ativos baseados em fluidos magneto-reológicos (MR) já são empregados no controle de vibrações desde máquinas de lavar a grandes pontes

4. Controle de vibrações em edifícios submetidos à ação de cargas dinâmicas utilizando amortecedor de massa sintonizando na forma de pêndulo / Vibration control of structures subjected to dynamic loads using tuned pendulum-shaped mass dampers
The ongoing progress of structural analyses and dimensioning, in addition to the continuous advancements in building techniques and material, has made it possible to build taller and more slender structures every day. These structures are also more vulnerable to excessive vibrations caused by dynamic loads like earthquakes, winds, waves, intense traffic, and

5. Skyhook control of a hydropneumatic suspension system developed for use in agricultural farm wagons / Controle Skyhook aplicado a um modelo de suspensão hidropneumatica para carretas agricolas
This study deals with the development of a control system suited for a Hydropneumatic Suspension System designed for use in Agricultural Devices. Using the Skyhook Control methodology, two control systems are designed for a quarter car non-linear model, an active and a semi-active one. For performance measurement, two kinds of road excitation sources are con

6. Modeling of a vehicle suspension with non linear elements and performance comparison to a semi-active model / Modelagem de uma suspensão veicular com elementos não lineares e comparação de seu desempenho com um modelo semi-ativo
This work describes the analysis and comparison of a vehicle suspension semi-active controlled to a non linear passive system. The mathematic model of a suspension system, detailed in this work, has seven degrees of freedom in order to represent a full vehicle system. The two semi-active control laws used in this work are based on the skyhook theory. In the

7. Controle semi-ativo em suspensões automotivas
In this thesis, it was developed a study of the principal sorts of semi-active car suspensions. The possibility of a semi-active suspension system depends on the costs envolved, the hardware available, and the control algorithm. To show how this subjects influence the conception process of a car suspension, we compiled some algorithms and proposed an altemat
