The article describes a control architecture for solar furnaces where active cooling is employed to improve the tracking of a time-varying temperature reference. This capability is important during the decreasing phase of the temperature reference where heat loss must be increased. The results of two different control methodologies, exact linearization and model predictive control with integral action,...
The Azores archipelago is a zone with a vast cultural heritage, presenting a building stock mainly constructed in traditional stone masonry. It is known that this type of construction exhibits poor behaviour under seismic excitations; however it is extensively used in seismic prone areas, such as this case. The 9th of July of 1998 earthquake was the last seismic event in the islands, leaving many...
XL CALPHAD—Computer Coupling of Phase Diagrams and Thermochemistry conference was held in Rio de Janeiro, Brazil, May 22–27, 2011. The conference had an audience of 192 persons. There were 88 oral and 100 poster presentations.Presentations were divided according to themes: ab initio; the CALPHAD method, and assessments; applications – energy; applications – steel, superalloys, oxides and experiments...
This paper describes the work on temperature modelling of an Electronic Detection Cell (EDC) for DNA analysis. The EDC is part of a biochip which is under development at INESC. The main goal of the project is to build a handheld biochip with several sites for running simultaneous detection experiments with independent temperature profiles. The basic DNA detection electronic cell comprises a Thin Film...
