Graphite dispersions as a basis for development of high thermal conductivity fluids
Both conductivity and thermal resistivity measurements of commercial graphite dispersions in non-aqueous polar fluids and non-polar fluids were carried out. Fluids exhibiting different densities as: mineral oil, ethylene ...
Energy balance in the watershed of Ipê, Northwestern São Paulo State, Brazil
The region of Ilha Solteira, in the Northwestern of São Paulo State, has been undergoing significant changes in agricultural land use and cover since 2006, as pasture fields have been replaced by sugarcane crop. This drastic ...
Diagnostic Support for Alzheimers Disease through Feature-Based Brain MRI Retrieval and Unsupervised Distance Learning
Initial stages of Alzheimer's disease are easily confused with the normal aging process. Additionally, the methodology involved in the diagnosis by radiologists can be subjective and difficult to document. In this scenario, ...
Dublin core and CIDOC CRM harmonization
Transmission lines model with different basic structures applied to transient electromagnetic simulations
Models based on lumped elements are simple ones to represent systems composed by distributed parameters when models with lumped elements use a lot of these elements. However, such mentioned models usually present numerical ...
Use of geophysical logs to map aquifers electrofacies
Map of geophysical parameters in different depth and their corresponding geological interpretations are analyzed based on an automatic geostatistical method to aquifers electrofacies identification using geophysical well ...
Characterization of unsaturated tropical soil site by in situ tests
Geotechnical site characterization consists in determining the stratigraphical profile, the groundwater level and the estimative of geo-mechanical designs parameters required for each project. In situ tests techniques can ...
Optimal volt-VAr control operation for energy cost reduction in distribution systems considering a voltage dependent load model
In this paper, a new mixed integer linear programming formulation is proposed to optimally control the Volt-VAr control devices installed in a balanced electrical distribution system (EDS), taking into account the presence ...
