Enraizaimento de estacas de Bougainvillea spectabilis Willd. com o uso de ácido indolbutírico

Desenvolvimento de Linked Data Mashups com o uso de LIDMS

Semantic Web technologies like RDF model, URIs and SPARQL query language, can reduce the complexity of data integration by making use of properly established and described links between sources. However, the di culty to formulate distributed queries has been a challenge to harness the potential of these technologies due to autonomy, distribution and vocabulary of heterogeneous data sources. Thi...

Um Esquema Completo Para Proteção Rápida De Linhas De Transmissão Com O Uso De Equações Diferenciais

This paper presents a complete scheme for protection of transmission lines, including fault detection, fault classification as well as fault location. The fault location module utilizes the modeling of transmission lines through their differential equations. The differential equation for the line is solved having its resistence and inductance as parameters. In this approach there is no need for...

Classificação Semiautomatica de areas queimadas com o uso de redes neurais

This paper presents an approach to improve the semi-automatic detection of burned areas through the use of neural networks. The approach is validated over a selected study area in the Brazilian Cerrado against reference data derived from data classified by experts. Methods are still being developed and improved, and initial results corroborate the validity of the approach, which will be extende...

Dinamica fluvial do rio Amazonas entre Manaus e Itacoatiara com o uso de imagens de satelite

The Amazon river is subject to major geomorphological changes between the hydrologic periods of flood and dry. Such changes can be mapped and detected by remote sensing techniques. In this context, this research had as objective to evaluate the dynamics of this great fluvial system, in the stretch between the cities of Manaus and Itacoatiara, in the period of 20 years. The results showed the pr...
