1. Um mecanismo construtivista para aprendizagem de antecipações em agentes artificiais situados / Un mecanisme constructiviste d'apprentissage automatique d'anticipations pour des agents artificiels situes / A constructivist anticipatory learning mechanism for situated artificial agents
Esta pesquisa caracteriza-se, primeiramente, pela condução de uma discussão teórica sobre o conceito de agente autônomo, baseada em elementos provenientes dos paradigmas da Inteligência Artificial Situada e da Inteligência Artificial Afetiva. A seguir, a tese apresenta o problema da aprendizagem de modelos de mundo, fazendo uma revisão bibliográfica

2. A historical study of the evolution of vector potential in classical electromagnetic theory / Um estudo histórico da evolução do conceito de potencial vetor no eletromagnetismo clássico
Currently the vector potential generally is considered in the classical electromagnetic theory as an artifice for the calculation of the electric and magnetic fields and without a clear physical meaning. However, when it was proposed in the mid-nineteenth century, it used to have a clear physical meaning and played a central role for Faraday, Maxwell and oth

3. Active magnetic bearing applied to a tubular linear induction motor. / Mancal magnético ativo aplicado a um motor de indução linear tubular.
A tubular linear induction motor applied to onshore oil exploitation, named MATÆOS (which is in the Portuguese acronym for Tubular Asynchronous Motor for Onshore Oil Exploitation) was built at Escola Politécnica da Universidade de São Paulo (EPUSP). Its purpose is to directly drive the sucker-rod pump installed in the down hole of the oil well. In continu

4. Environmental technical nets : diversity and connection between people and places / Redes tecnicas ambientais : diversidade e conexão entre pessoas e lugares
The possibilities for construction or improvement of the urban sustainability level, in social and environmental dimension, are the base of the present work. The process of urban sustainability is analyzed and discussed based on the environmental technical nets formed by urban green spots that offer environmenal services. To analyze the potential of creation

5. Analysis of the promiscuous gene expression in the thymus of NOD (non obese diabetic) mice during onset of type 1 diabetes mellitus / Análise da expressão gênica promíscua no timo de camundongos NOD (non obese diabetic) durante a emergência do Diabetes melitus tipo 1
Immunologic tolerance is an essential property of the immune system, which controls immune reactions directed against the body self components. The thymus is seen as the main organ involved with the tolerance induction to self antigens, which are expressed by the thymic cells (central tolerance), while the tolerance induction to the diverse other peripheral

6. MAPEAMENTO E DELEÇÃO DE EPÍTOPOS LINEARES DE LINFÓCITOS B EM PROTEÍNAS DO VÍRUS DA SÍNDROME RESPIRATÓRIA E REPRODUTIVA DOS SUÍNOS PARA A PRODUÇÃO DE UMA VACINA DIFERENCIAL / MAPPING AND DELETION OF B-CELL LINEAR EPITOPES IN PROTEINS OF PORCINE REPRODUCTIVE AND RESPIRATORY SYNDROME VIRUS FOR THE PRODUCTION OF A DIFFERENTIAL VACCINE
Porcine reproductive and respiratory syndrome virus (PRRSV) was isolated for the first time in 1991 and since then it has been associated with significant economic losses to the pig industry worldwide. Although vaccination against PRRSV is widely used, an important advance would be the development of marker vaccines allowing serologic discrimination between

7. CONTRIBUIÇÃO AO ESTUDO DA MÁQUINA ASSÍNCRONA TRIFÁSICA DUPLAMENTE ALIMENTADA APLICADA A AEROGERADORES DE VELOCIDADE VARIÁVEL
This work presents the analysis and implementation of a vector control applied to Doubly-Fed Induction Generators (DFIG) used in grid connected wind turbines. DFIGs are nowadays the more widely used concept for grid connected wind turbine, especially for rated power above 1 MW. The main reason is the low rotor PWM power converter rating. The present work dea

8. As diferentes dimensões da sustentabilidade em uma organização da sociedade civil brasileira: o caso do GAPABahia.
What is sustainability? How does one deal with the issue of sustainability in the field of a civil society organization (CSO), within the Brazilian context? This present dissertation, developed in the Academic Masters Program of Administration at the Federal University of Bahia, entitled Different dimensions of sustainability in a Brazilian civil society org

9. WIND TURBINE: MODELING, ANALYSIS AND CONTROL OF DOUBLY FED INDUCTION GENERADOR / TURBINAS EÓLICAS: MODELO, ANÁLISE, E CONTROLE DO GERADOR DE INDUÇÃO COM DUPLA ALIMENTAÇÃO
This thesis presents the main concepts and configurations used in wind turbine connected to the grid, as well as, an analysis, design and implementation of the control system for the Doubly Fed Induction Generator (DFIG). The DFIG has been selected since it is the concept frequently adopted by the wind turbine manufactures. In the thesis, it is presented a m

10. Descompasso entre estilo de ensino/aprendizagem e os objetivos dos alunos
This work is based on the assumption that there are two essential learning and teaching styles--sensorial and intuitive--divided into five dimensions (sensorial/intuitive; visual/verbal; active/reflective; sequencial/global; deductive/inductive). The focus will be on the last dichotomy, which refers to the two ways of processing information. In language teac

11. O reescrever em contexto escolar: um estudo sobre produÃÃo de textos no Ensino MÃdio
This thesis aims at describing and to interpreting clues of the process of writing in six texts - two argumentative texts, two letters to the editor and two fantastic narratives -, written in two or three versions. There are sixteen texts altogether produced by two students from the first year of secondary school in the city of Cabo de Santo Agostinho, first

12. Fever induction pathways: evidence from responses to systemic or local cytokine formation
The immune and central nervous systems are functionally connected and interacting. The concept that the immune signaling to the brain which induces fever during infection and inflammation is mediated by circulating cytokines has been traditionally accepted. Administration of bacterial lipopolysaccharide (LPS) induces the appearance of a so-termed "cytokine c
