13. Locally nilpotent derivations of certain finitely generated k-algebras / Derivações localmente nilpotentes de certas k-algebras finitamente geradas
This work is dedicated to the study of locally nilpotent derivations of certain finitely generated K-algebras, where K is a field of zero characteristic. These domains are generalizations of the well-known rings in the literature. One of this is the Fermat ring. More precisely, we characterize the set of locally nilpotent derivations of these domains or some

14. Metodologia de estimação de parâmetros de sistemas dinâmicos não-lineares com aplicação em geradores síncronos / Parameter estimation methodology of dynamical nonlinear systems with application in synchronous generators
Este trabalho apresenta uma nova metodologia para estimar parâmetros de geradores síncronos baseada na análise de sensibilidade de trajetória. Esta nova metodologia foi concebida com o objetivo de suplantar dificuldades de convergência que a metodologia de sensibilidade de trajetória tradicional apresenta devido a: (i) baixa robustez com relação aos

15. Application generation for aspect oriented product lines with Captor-AO tool / Geração de aplicações para linhas de produtos orientadas a aspectos com apoio da ferramenta Captor-AO
A Software Product Line (SPL) consists of a set of software systems that share common features and fulfill the specific requirements of a particular domain. In order to make the products instantiation process faster and less prone to errors, the project of a SPL can adopt the utilization of application generators, which can can automatically generate the SPL

16. Estudo de soluções do fluxo de potência em coordenadas cartesianas
This work presents the modelling and some methodologies to solve the steady state power network equations in rectangular coordinates, including the determination of the critical loadability. Firstly, four methods are presented, from the conventional application of the Newton-Raphson method to some approaches proposed more recently in the literature. Addition

17. Uma contribuição à modelagem de complexos eólicos contendo geradores especiais para atenuação das componentes harmônicas
Most of the wind energy conversion systems (WECS) currently in operation in the world use asynchronous generators in the transformation of wind energy into electricity energy. In Brazil, although it is recognized that the parcel of wind farms is still very reduced, it is evidenced that the principle of the employed generation is mainly synchronous. Within th

22. Model predictive control for Francis hydro turbine generators / Controle preditivo baseado em modelo para turbo-geradores hidraulicos tipo Francis
Despite being used in the industry for more than 20 years, Model Predictive Control (MPC) has not found many applications in the field of rotating machinery controI. The majority of the applications today are chemical and petrochemical processes. However, some results obtained by other authors for the control of gas and steam turbines, suggest that its use c
