Algoritmos paralelos e adaptativos no tempo e no espaço para simulação numérica da eletrofisiologia do coração

Computational models have become valuable tools for the study of the electrical behavior of the heart. However, the high complexity of the biophysical processes translates into expensive computational models. In this work we propose, implement and combine strategies using parallel computing and graphical processing unit (GPU), adaptive meshes in space and time adaptive methods in order to reduc...

Interoperabilidade e Portabilidade de Documentos Digitais Usando Oontologias

Our purpose is to enable interoperability of documents and achieve portability of digital documents through the reuse of content and format in different plausible combinations. We propose the characterization of digital documents using ontologies as a solution to the problem of lack of interoperability in the implementations of document formats. As proof of concept we consider the portability b...

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. As result, we have a wide-coverage ontological resource th...

Mensuração da disponibilização de informações e do nível de interação dos ambientes informacionais digitais da administração municipal com a sociedade

The question about value of using information as competitive differential and critical factor of success both in private and in public dimension has obtained increased distinction. Enterprises and public power are worried about questions related to formation of an information society, aiming to maintain the means of production competitive and, in case of public administrations to improve the so...
