3. Tópicos em seleção de modelos markovianos / Topics in selection of Markov models
This work related two statistical problems involving the selection of a Markovian model of finite order. Firstly, we propose a procedure to choose a context tree from independent samples, with more than half of them being realizations of the same finite memory Markovian processes with finite alphabet with law P. Our model selection strategy is based on estim

4. Avaliação de usabilidade em bibliotecas digitais: um estudo de caso
The digital libraries aim to make available information to their users in a faster and easier way. In these libraries, the interactions of users with the collections is carried out by means of their interfaces. Bearing in mind the importance of the role performed by these interfaces, that is, as a link between user and system, this study proposes a case stud

12. Optimum design applied to electrooptic modulators / Projeto ótimo de moduladores eletroópticos
Many design developments involve the optimization of several objective functions. These objective functions are often conflicting with each other and they cannot be simply aggregated into only one function to be optimized. This type of problem is known as the multiobjective optimization problem, for which the solution is a set of points known as Pareto optim
