2. Lógica fuzzy: reflexões que contribuem para a questão da subjetividade na construção do conhecimento matemático / Fuzzy logic: reflections that contribute to the question of subjectivity in the building of mathematical knowledge.
A pesquisa de cunho qualitativo aqui apresentada tem como propósito discutir o valor e o papel da lógica fuzzy na solução de problemas reais, dada a característica de suas ferramentas para lidar com questões subjetivas, uma vez que as soluções de problemas provenientes do mundo real estão carregadas de relações construídas no mundo interno do res

3. Sistema especialista fuzzy para dimensionamento de bombeio mecânico
Despite the emergence of other forms of artificial lift, sucker rod pumping systems remains hegemonic because of its flexibility of operation and lower investment cost compared to other lifting techniques developed. A successful rod pumping sizing necessarily passes through the supply of estimated flow and the controlled wear of pumping equipment used in the

4. AnÃlise de atenuaÃÃo de sinal em ambientes indoor usando lÃgica nebulosa / Analysis of signal attenuation for Indoor Environments using Fuzzy Logic
Due to the increasing demand for services related to wireless networks, such as video, voice and video conferencing and to the concern of telecommunications companies to meet this demand efficiently, the planning of a wireless link becomes very important. Since the propagation of a signal over a wireless network is not driven, it can suffer attenuation cause

5. The Interval Constructor on classes of ML-algebras
Monoidal logic, ML for short, which formalized the fuzzy logics of continuous t-norms and their residua, has arisen great interest, since it has been applied to fuzzy mathematics, artificial intelligence, and other areas. It is clear that fuzzy logics basically try to represent imperfect or fuzzy information aiming to model the natural human reasoning. On th

6. Análise de crédito utilizando inteligência artificial: validação com dados do cartão BNDES / Credit analysis based on artificial intelligence: validation with data of BNDES card
O presente trabalho apresenta um estudo feito para a elaboração de um modelo de análise de crédito para micro, pequenas e médias empresas (MPME) utilizando Inteligência Artificial. Apresenta, também, uma contribuição de um novo método de raciocínio baseado em casos, denominado FISKNN, que utiliza medida de similaridade presente nos métodos KNN e

7. FUZZY EVALUATION OF SOCIAL EXCHANGES BETWEEN PERSONALITY-BASED AGENTS / Avaliação Fuzzy de Trocas Sociais entre Agentes com Personalidades
Piagets Theory of Social Exchanges has been used as the basis for interaction analysis in Multiagent Systems. These interactions are understood as processes of service exchanges between pairs of agents followed by the the evaluation of those services by the agents involved in the processes, producing values of social exchanges. The values emerged form those

8. Rede Neural Difusa com T-normas Diferenciáveis e Interativas
Fuzzy sets are used in the representation of vague and imprecise knowledge. Neural networks, besides their computational parallelism, also have learning capabilities. The combination of such both paradigms is an attempt to congregate their benefits in an integrated system, such a fuzzy neural network. T-norms are functions that actuate like intersection and

9. Topological dimension and self organizing maps / Dimensão topologica e mapas auto organizaveis de Kohonen
Redes Neurais Artificiais Auto-Organizáveis (RNA-AO), introduzidas por Teuvo Kohonen na década de 60, constituem uma poderosa ferramenta para análise de dados, mais especificamente para análise de agrupamentos, visualização e aproximação de superfícies. Nesta tese definiu-se uma nova forma para determinar a dimensão topológica do espaço de saída

10. Raciocinio difuso via logicas moduladas : uma solução ao paradoxo do Sorites
This work studies the concept of vagueness, analyzing their main characteristics and criticizing the viability of Fuzzy Logic to express vague predicates. Vle conclude by showing several debatable points on this use of Fuzzy Logic. Looking for an appropriate logic to express vagueness we study the Modulated Logics, and conclude that they are better suited th

11. IDENTIFICAÇÃO DE GRUPOS ESTRATÉGICOS: UMA ABORDAGEM UTILIZANDO A VISÃO RESOURCE-BASED E SISTEMAS NEURO-FUZZY / STRATEGIC GROUPS: ARESOURCE-BASED VIEW AND NEURO-FUZZY SYSTEMS APPROACH
Since its has introduced, in the beginning of the decade of seventy, the concept of strategic groups is object of theoretical and empirical research that aims to confirm its existence, its contribution to performance evaluation and the formulation of the strategies of the firms. This text join these research, using the Resource-Based Views framework and soft

12. Desenvolvimento de uma plataforma hÃbrida para descoberta de conhecimento em bases de dados
Artificial Neural Networks (ANN) have successfully been used in tasks as the mapping of complex functions and pattern recognition. This success is due to the ANN ability to make calculations of complicated and undetermined data, learn from examples, generalize the learned information, extract patterns and discover tendencies. Despite these advantages, it is
