13. SISCTG- an intelligent systems for classification of cardiotocography signals for help diagnosis doctor / SISCTG - Sistema para AnÃlise Computadorizada da FrequÃncia CardÃaca Fetal
The accurate analysis of the fetal heart rate (FHR) and its correlation with uterine contractions (UC) allows the diagnostic and the anticipation of many problems related to fetal distress and the preservation of his life. This dissertation presents the results of an hibrid system based on a set of deterministic rules and fuzzy inference system developed to

14. Fuzzy set in the evaluation of the conservation state of the land use systems in the Occidental Amazonia, using beetles (Scarabaeidae) as bioindicators. / Conjuntos Fuzzy na avaliaÃÃo do estado de conservaÃÃo de sistemas de uso da terra na AmazÃnia Ocidental, usando besouros (Scarabaeidae) como bioindicadores
Currently the land is losing species much more quickly than it was some decades ago, and the human being is the main causer of this extinguishing. Biodiversity is in the basis of all survival human being, therefore it is indispensable to keep the evolution processes of the alive world acting in the regulation of the great physico-chemical equilibrium of the

15. Um sistema de recomendação para mídias baseado em conteúdo nebuloso.
This work presents the development of a content-based recommender system for media of the AMMO (Authoring and Manipulation of Multimedia Objects) environments multimedia database. This environment keeps inexact semantic information that describes the media. This projects objective was to recommend media using this fuzzy information. Other informations that s

16. SiMCaPe - Sistema para a montagem de cariótipo de peixe baseado em conjuntos difusos
The karyotype study of several organisms has a its objective to observe numerical variations, for detecting specific characteristics and to study the evolution of the species. Manual assembling of karyotype is a repetitive, subjective and time consuming task. This project describes the SiMCaPe, an interactive system for assisting the assembling of fish karyo

17. LIBERAÇÃO AUTOMÁTICA DOS EXAMES LABORATORIAIS HORMÔNIO FOLÍCULO ESTIMULANTE E ESTRADIOL DE MULHERES EM FASE REPRODUTIVA
This work proposes an informational system for a clinical laboratory to control the post analytical phase of the exams. The system can automatically liberate the results of clinical exams. To assess the system we developed a prototype able to liberate FSH and Estradiol hormones based on rules that confront FSH and Estradiol results. The prototype was able to

18. Controle automático de adição de alf3 em cubas de redução de alumínio, usando lógica fuzzy / Automatic control of addition of alf3 in cubas of aluminum reduction, using logical fuzzy
This work describes a data analysis system, which generates an intelligent aluminum fluoride (AlF3) addition strategy for electrolytic cells. The project is based on Fuzzy logic concepts, wherein the knowledge accumulated by the process specialist is translated in a qualitative manner into a set of linguistic rules such as: IF

19. On-line control of a flexible beam using adaptive fuzzy controller and piezoelectric actuators
This paper presents a design of adaptive fuzzy controllers applied to the control of vibrations in flexible structures containing distributed piezoelectric actuator patches. The adaptive fuzzy controller is constructed from a set of fuzzy IF-THEN rules whose parameters are adjusted on-line according to some adaptation law. The adaptive law is derived based o

20. Uso de relações de similaridade para tratamento de consistência e cobertura em sistemas de regras difusas / The use of similarity relations to deal with consistency and covering problems in systems of fuzzy rules
This work presents the use of similarity relations to deal with inconsistency and covering problems that may occur in a knowledge base with rules of the type "If X is Ai then Y is Bi", where Ai and Bi are fuzzy sets. The work is focused on systems using implicative fuzzy rules based systems, i.e, in which the if-then operator is implemented by a truly implic

21. Sintese de um controlador hibrido fuzzy-preditivo : aplicação para processos de polimerização
This work presents the development of a new predictive controller based in functional fuzzy models for polymerizatíon processes. These processes present a highly non-linear dynamic behavior, thus making difficult the development of controllers based on model as conventional predictive controllers. Two case studies were considered to analyse the performance

22. Obtenção das funções de pertinência de um sistema neurofuzzy modificado pela rede de Kohonen
This dissertation presents an hybrid computational model that combines fuzzy system techniques and artificial neural networks. Its objective is the automatic generation of membership functions, in particular, triangle forms, aiming at a dynamic modelling of a system. The model is named Neo-Fuzzy-Neuron Modify by Kohonen (NFN-MK), since it starts using Kohone

23. APPLICATION OF FUZZY LOGIC TO THE MUHLBAUER MODEL FOR PIPELINE RISK ANALYSIS / APLICAÇÃO DA LÓGICA NEBULOSA AO MODELO MUHLBAUER PARA ANÁLISE DE RISCO EM DUTOS
W. Kent Muhlbauer made a detailed identification of approximately 300 different conditions that influence in the evaluation of the Risk in a pipeline, so, He proposed a punctuation system that is known as the method of Muhlbauer. Muhlbauer`s method evaluates the several variables that influence in the pipeline Risk by the attribution of quantitative values.

24. SimulaÃÃo de sistemas complexos para fins de entretenimento usando Redes Bayesianas: o caso do FutSim
The purpose of this work is to meet the Artificial Intelligence requirements of FutSim, an online soccer management game developed by Jynx Playware. Computer games are relevant today not only because of their economical importance, but also for research purposes. Soccer is an excellent example of a Complex System, since its understanding is not possible thro
