Uso de correntropia na generalização de funções cicloestacionárias e aplicações para a extração de características de sinais modulados

Information extraction is a frequent and relevant problem in digital signal processing. In the past few years, different methods have been utilized for the parameterization of signals and the achievement of efficient descriptors. When the signals possess statistical cyclostationary properties, the Cyclic Autocorrelation Function (CAF) and the Spectral Cyclic Density (SCD) can be used to extract...

Extração e Validação de Ontologias a partir de Recursos Digitais

This paper aims at presenting a methodology for semi-automatic validation of an wide-coverage ontology based on an existing electronic resource, PAPEL. From the existing relations, we choose those of synonymy and hypernymy to generate the ontology. The resulting output was converted to OWL format e manually validated by a lexicographer.
