1. A Novel In Silico Monte Carlo Approach to Optimize a PSD Estimation Problem. Generation of Data Fusion Experiment Rules
ABSTRACT This article analyzes the performance of combining information from Scanning Electron Microscopy (SEM) micrographs with Static Light Scattering (SLS) measurements for retrieving the so-called Particle Size Distribution (PSD) in terms of experimental features. The corresponding data fusion is implemented using a novel Monte Carlo-based method consist

2. Filtragem robusta recursiva para sistemas lineares a tempo discreto com parâmetros sujeitos a saltos Markovianos / Recursive robust filtering for discrete-time Markovian jump linear systems
Este trabalho trata de filtragem robusta para sistemas lineares sujeitos a saltos Markovianos discretos no tempo. Serão desenvolvidas estimativas preditoras e filtradas baseadas em algoritmos recursivos que são úteis para aplicações em tempo real. Serão desenvolvidas duas classes de filtros robustos, uma baseada em uma estratégia do tipo H \ INFINITO\

3. Estimação de estado em sistemas elétricos de potência: composição de erros de medidas / State estimation in power systems: measurement error composition
Bretas et al. (2009) has proved, using geometric background, that the measurement error can be decomposed into two components the detectable and the undetectable component respectively. Bretas has also demonstrated that the current methodologies used for processing of gross errors (GE), consider only the detectable component of the error. Thus, depending on

4. Estratégia Híbrida para recomendação personalizada utilizando o Guia de Programação Eletrônico. / Hybrid Strategy for personalized recommendation using the Electronic Program Guide.
The wide range of digital information has become more difficult to find things that best fit the profile of those who demand something. In this context, Recommender Systems represent a solution to the above problem, since they help the user to find relevant information, operating based on information personalization, since it helps certain individuals in the

5. Study of special modulation formats for optical communication / Estudo de formatos especiais na modulação digital para comunicações ópticas
This MSc thesis investigates optical modulation formats as an alternative to the use of the traditional intensity binary format NRZ (Non-return-to-zero). Those formats, classified as advanced, represent one of the key technologies aimed to enable the high data volume and broadband, demanded by the present telecommunication market, with cost reduction of tran

6. RAVE au DISCO: recomendaÃÃo automÃtica de vÃdeo como auxÃlio no processo de disseminaÃÃo do conhecimento
In recent years, we have observed a significant growth in the production of multimedia content. It is remarkable to highlight that much of such content is spread out using the Internet infrastructure. However, some characteristics of the content access have made non-trivial the process of lookup for and retrieval of content. Difficulties to access multimedia

7. Análise da transformada wavelet direcional adaptativa na codificação de imagens
This work presents a method for the numerical stability analysis of adaptive lifting-based directional transforms. The goal is to investigate the relation between the directions set in the lifting scheme and the reconstruction quality of the corresponding bases. This new method is based on the variation in frequency of the condition number of the synthesis p

8. DESENVOLVIMENTO DE UMA FAMÍLIA DE SISTEMAS DE RECOMENDAÇÕES BASEADOS NA TECNOLOGIA DA WEB SEMÂNTICA E SEU REUSO NA RECOMENDAÇÃO DE INSTRUMENTOS JURÍDICO-TRIBUTÁRIOS / DEVELOPMENT OF A FAMILY OF SYSTEMS BASED ON RECOMMENDATIONS OF TECHNOLOGY AND ITS SEMANTIC WEB REUSE IN RECOMMENDATION OF LEGAL INSTRUMENTS-TRIBUTARIES
The huge amount of data available on the Web and its dynamic nature create a demand for information filtering applications such as recommender systems. The lack of semantic structure of data available on the Web constitutes a barrier for increasing the effectiveness of such applications family. This work discusses the analysis, design, implementation and eva

9. BOOSTING FOR RECOMMENDATION SYSTEMS / BOOSTING PARA SISTEMAS DE RECOMENDAÇÃO
With the amount of information and its easy availability on the Internet, many options are offered to the people and they, normally, have little or almost no experience to decide between the existing alternatives. In this scene, the Recommendation Systems appear to organize and recommend automatically, through Machine Learning, the interesting items. One of

10. UM MODELO DE SISTEMA DE FILTRAGEM HÍBRIDA PARA UM AMBIENTE COLABORATIVO DE ENSINO APRENDIZAGEM / A MODEL SYSTEM FOR A HYBRID COLLABORATIVE FILTERING LEARNING ENVIRONMENT OF EDUCATION
A Web é uma excelente fonte de informação, mas um dos problemas que surgem com a grande disseminação de informações é a dificuldade de se obter informação relevante em tempo hábil e de forma precisa. Mecanismos que auxiliem o usuário na recuperação de informações tais como o Google.com, Altavista e Cadê, muitas das vezes retornam uma grande

11. A knowledge based process model to support alternative conflict resolution. / Um modelo de processo baseado em conhecimento para apoiar a solução extrajudicial de conflitos.
This research presents the definition of a game model, adapted to represent the alternative dispute resolution processes, according to which an abstract model is proposed, splitting the negotiation in steps. By the description of each step, the objectives, and necessary tasks to achieve them, are identified. Based on the researches presented, for each step,

12. SPECIFICATION OF A MULTI-AGENT SYSTEM RECOMMENDATION FOR ACTION IN CASE OF FAILURES OF SYSTEMS AUTOMATION IN CONTROL / ESPECIFICAÇÃO DE UM SISTEMA MULTIAGENTE DE RECOMENDAÇÃO DE AÇÕES EM CASO DE FALHAS DE SISTEMAS DE AUTOMAÇÃO E CONTROLE
When equipment failure occur in complex industrial plants, the automation and control system generates a great amount of alarms that can confuse the operators and lead them to take wrong decisions - the time for decision taking is very short and the amount of generated information is higher, being impossible for the operator read all of them before taking th
