Técnicas em Processamento e Análise de Documentos Manuscritos

This work aims to present the main modules of a typical Handwriting Document Processing and Analysis System (HDPAS): data acquisition, preprocessing, segmentation, feature extraction and recognition. First, the relevant aspects of each HDPAS process are given, different types of documents, filtering and segmentation techniques applied to extract the interested data. Then, the main Hidden Markov...

Contribuições em escalonamento e análise de desempenho de redes WirelessHART

Wireless Communication is a trend in the industrial environment nowadays and on this trend, we can highlight the WirelessHART technology. In this situation, it is natural the search for new improvements in the technology and such improvements can be related directly to the routing and scheduling algorithms. In the present thesis, we present a literature review about the main specific solutions ...

Modelagem e análise de conectividade em redes sem fios obstruídas

Connectivity properties of wireless networks in open space are typically modeled using geometric random graphs and have been analyzed in depth in different studies. Such scenarios, however, do not often represent situations encountered in practice, like urban environments or indoor spaces, which are deeply affected by obstacles. As an alternative, we propose a model for obstructed wireless ad h...

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 ...
