1. Selecting the system most likely to be the best in the presence of an infinite number of alternatives
Simulation Optimization (SO) belongs to a broader class of problems called Stochastic Optimization. Most of the proposed SO methodologies in the literature aim to optimize the expected value of the performance measure. This thesis focus is on another class of problems: Multinomial Selection Procedures (MSPs). These procedures select the best alternative, whe

2. A comunicação escrita em Inglês como língua estrangeira: uma experiência de pen pal eletrônico entre alunos brasileiros e estrangeiros / Written communication in English as a foreign language: a experience of electronic pen pal from Brazilian students and foreign
This study addresses a digital pen pal experiment in May-June 2009 involving six Brazilian students and their foreign peers living in Canada. This is an exploratory study involving real communication situations under a teaching activity where the researcher was also the class teacher. The experiment took place during an English course in the Federal, Educati

3. Regressão de dados binários : distribuição Weibull
In this work a new class of models for binary data based on Weibull distribution is introduced. A review is made of the most known linkage functions. This class of models has as special case the complementary log-log model and approximates well the logit and probit models. Three real data sets are given to compare the proposed model with many others. In one

4. Students algebraic thought and language manifestations: indicators for teaching organization. / Manifestações do pensamento e da linguagem algébrica de estudantes: indicadores para a organização do ensino.
This work deals with the students difficulties about algebraic knowledge, which could be related to the specificities of algebra, to educational methodology and didactical matters, and also to language and thought psychological processes. Therefore, the subject of study is the studentsthoughts and their algebraic language. We understand that thought and lang

5. Feature selection and intrinsically multivariate prediction in gene regulatory networks identification / Seleção de características e predição intrinsecamente multivariada em identificação de redes de regulação gênica
Feature selection is a crucial topic in pattern recognition applications, especially in bioinformatics, where problems usually involve data with a large number of variables and small number of observations. The present work addresses feature selection aspects in the problem of gene regulatory network identification from expression profiles. Particularly, we

6. Contribuição ao estudo de aerogeradores de velocidade e passo variáveis com gerador duplamente alimentado e sistema de controle difuso / Contribution to the study of fuzzy control applied to variable-speed variable-pitch wind generators with double-fed induction generator
The efficient capture of aeolic-energy occurs by means of three blades turbines with adjustable pitch-angle and angular-speed. The pitch-angle adjustment is utilized to limit the aeolic-energy capture when occur very strong winds and, the angular speed adjustment is utilized to maximize the capture of kinetic energy of weak winds. In this mode of operation t

7. Um ambiente virtual para o ensino semipresencial de funções de uma variável real: design e análise
Nesta pesquisa objetivamos a elaboração e implementação de um ambiente virtual para um curso semipresencial, para estudantes dos cursos de Bacharelado em Ciência da Computação e Sistemas de Informação de uma instituição particular na cidade de São Paulo, dependentes na disciplina que aborda tópicos de pré-calculo. Nosso foco recaiu na análise

8. Regressão logística uma estimativa Bayesiana aplicada na identificação de fatores de risco para HIV, em doadores de sangue.
Logistic regression has application in several fields as epidemiology, medical research, banks, market research and social research. One of its advantages is that the interpretation of the measure is possible through the " Odds Ratios (OR), that are functions of the parameters of the model. In this study the binary regression model was used, with the objecti
