Análise e modelagem do comportamento de SPAMMERS e dos usuários legítimos em redes de email

Email is an increasingly important and ubiquitous mean of communication, both facilitating contact between individuals and enabling rises in the productivity of organizations. However, the relentless rising of automatic unauthorized emails, also known as spam, is eroding away much of the attractiveness of email communication. Most of the attention dedicated to spam detection has focused on the ...

Análise do Impacto do Gerador de Conjuntos de Dados em Experimentos de Deduplicação de Dados

Using tools to create synthetic datasets is the only solution for evaluating data duplication algorithms when real datasets are not available. However, the evaluation results may be affected by the diversity and levels of parameters available in such tools. Our goal is to verify which parameters and levels impact more on the results of deduplication experiments. Hence, we perform factorial proj...

Desenvolvimento de um sistema de análise de imagem para quantificação do tamanho e distribuição de partículas de desgaste

This paper describes the development of an image analysis system for wear particles found in industrial equipment lubricating oil. Hence, it was utilized an image acquisition system to capture image samples of the oil held in filter membranes. An analytical methodology was also developed to classify the particles quantitatively and qualitatively, relating them to the wear mode where they had be...
