13. Simulação do processo de adsorção psa para separação da mistura etanol-água / Simulation of the adsorption process psa for separation of ethanol-water mixtures
One of the problems with ethanol production is the high energy cost which is associated with the separation of ethanol due to of excess water and the existence of an azeotrope in the mixture ethanol-water, by conventional distillation the mixture can be separated up to 95% weight. Currently, there is great interest in the development of technological process

16. Modelagem geológica por simplóides de Bézier / Geological modeling using Bézier simploids
The exploration and monitoring of a hydrocarbon reservoir demand a very detailed knowledge about the geological structures of the target area. The mathematical and computation representation of this knowledge is a geophysical model. In this thesis, we describe a general system for geophysical modeling based on polynomial finite elements of arbitrary degree.
