13. Supercritical CO2 recovery of caffeine from green coffee oil: new experimental solubility data and modeling
The caffeine solubility in supercritical CO2 was studied by assessing the effects of pressure and temperature on the extraction of green coffee oil (GCO). The Peng-Robinson¹ equation of state was used to correlate the solubility of caffeine with a thermodynamic model and two mixing rules were evaluated: the classical mixing rule of van der Waals with two ad

14. Análise da influência de funções de distância para o processamento de consultas por similaridade em recuperação de imagens por conteúdo / Analysis of the influence of distance functions to answer similarity queries in content-based image retrieval.
The retrieval of images by visual content relies on a feature extractor to provide the most meaningful intrinsic characteristics (features) from the data, and a distance function to quantify the similarity between them. A challenge in this field supporting content-based image retrieval (CBIR) to answer similarity queries is how to best integrate these two ke

15. Subsídios à determinação de vazões ambientais em cursos d água não regulados : o caso do Ribeirão Pipiripau (DF/GO)
In river basins with strong urban and agricultural development, such as the highlands of Central Brazil, high water demands and extraction rates can lead to unwanted environmental and social impacts, particularly during low flow periods. Although the Brazilian legislation has provisions for the establishment of minimum flows in rivers, they are often underes

16. FUZZY MODELS IN SEGMENTATION AND ANALYSIS OF BANK MARKETING / MODELOS FUZZY NA SEGMENTAÇÃO E ANÁLISE DO MERCADO BANCÁRIO
Este trabalho tem como principal objetivo propor e desenvolver uma metodologia baseada em modelos fuzzy para a segmentação e caracterização dos segmentos que compõem o mercado bancário, permitindo um amplo conhecimento dos perfis de clientes, melhor adaptação das ofertas ao mercado e, conseqüentemente, melhores retornos financeiros. A metodologia pr

17. Destilado da desodorização do oleo de soja como suplemento de vitamina E / Soybean oil deodorizer distillate as a vitamin E supplement
Increased use of industrial waste and byproducts fits the need of industry to comply with environmental rules. The substitution of natural products for artificial ingredients has gained worldwide attention in the food, pharmaceutical and other industries. These facts justify the study on the utilization of Soybean Oil Deodorizer Distillate (SODD) as tocopher

18. 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

19. Information extraction from scientific articles: an approach based on induction of tagging rules / Extração de informação de artigos científicos: uma abordagem baseada em indução de regras de etiquetagem
Este trabalho faz parte do projeto de uma ferramenta denominada FIP (Ferramenta Inteligente de Apoio à Pesquisa) para recuperação, organização e mineração de grandes coleções de documentos. No contexto da ferramenta FIP, diversas técnicas de Recuperação de Informação, Mineração de Dados, Visualização de Informações e, em particular, técn

20. Um modelo de extração de propriedades de textos usando pensamento narrativo e paradigmático. / A model of textsproperties extraction using narrative and paradigmatic thinking.
This work seeks to understand how man formulates his thoughts and use them to act in the world. It is not our purpose to exhaust this subject, but to discuss it and present a model of how this process might possibly occur. For this we made a new lecture of the thinking modes studied by the psychologist Jerome Bruner in the 1980s: narrative thinking and parad

21. Study of allelic frequency of five X-Chromosome?s loci STR on Sao Paulo State people and its role in human identification / Estudo de freqüência alélica de cinco loci STR do cromossomo X na população do Estado de São Paulo e sua contribuição na identificação humana
The forensic identification through DNA analysis is, frequently, done by the study of DNA?s polymorphic regions, such as STR, short tandem repeats. In order to use these markers in human identification, it?s necessary to know the allelic distribution in the population in wich the person belongs. This research aimed to settle the allelic frequencies of five X

22. FUZZY RULES EXTRACTION FROM SUPPORT VECTOR MACHINES (SVM) FOR MULTI-CLASS CLASSIFICATION / EXTRAÇÃO DE REGRAS FUZZY PARA MÁQUINAS DE VETOR SUPORTE (SVM) PARA CLASSIFICAÇÃO EM MÚLTIPLAS CLASSES
This text proposes a new method for fuzzy rule extraction from support vector machines (SVMs) trained to solve classification problems. SVMs are learning systems based on statistical learning theory and present good ability of generalization in real data base sets. These systems have been successfully applied to a wide variety of application. However SVMs, a

23. Mineração de regras de associação em dados georreferenciados / Mining of association rules in geographic data
Geographic information systems are used to store, manipulate, and analyze spatial data and its descriptive aspects. Spatial data analysis can be done by searching association rules that describe relationships between the data. However, georeferenced data present topological relations unknown to traditional mining association rule algorithms. To solve this pr

24. INTEGRAÇÃO DE REPOSITÓRIOS DE SISTEMAS DE BIBLIOTECAS DIGITAIS E SISTEMAS DE APRENDIZAGEM / INTEGRATION OF REPOSITORIES OF DIGITAL LIBRARY SYSTEMS AND LEARNING MANAGEMENT SYSTEMS
With the widespread use of Information Technology for teaching support, it is usual to made digital content available through Digital Library Systems (DLMS) or Learning Management Systems (LMS).These systems, however, work independently, have different characteristics and manipulate different types of materials, and their data and metadata repositories are h
