Keywords: Enhanced Learning; Communities of Practice

Palette is an ‘Integrated Project’ financed by the IST (Information Society Technology) programme of the European commission dealing with knowledge sharing and appropriation within communities of practice.

Collaborative learning has an increased potential when it occurs in the context of a Community of Practice (CoP). Such communities have several components that distinguish them from formal organisations and learning contexts: it is recognised that they can be developed through the uses of network technologies. However, despite the rapidly increasing potential of these technologies (including web-based platforms, wireless communications, mobile devices and extensive use of multimedia contents), a lot of progress remains to be done in order to support individual learning process, as well as knowledge and identity building in them. The goal of Palette is to elaborate, implement and promote the use of an extensible set of interoperable services that appropriately address the needs of these communities.

Denis Gillet, Thierry Prud’homme

Keywords: Optimal Control, Hybrid Systems, Solar Thermal Systems, Hot Water Production, Heating Systems, Weather Forecasts

In this project, systems that use solar energy to provide the users with hot water are considered. An auxiliary heater is used when the solar energy is not able to meet the users’ requirements. The goal in this projects is to maximise the part of solar energy in final energy balances at the same time maximising the comfort. This is described by an optimal control problem and is solved using dynamic models of heat exchangers and the building. These models have been developed and the parameters have been identified on two pilot plants located at the Ecole d’ingenieurs d’Yverdon (EIVD). The one-day weather forecasts, provided on-line by the Swiss Meteorological Institute (SMI), are also used. Two systems are under investigation in this project. The first one is a solar domestic hot water system. The second one is called a combi-system, which provides the users with hot water in addition to heating the building.
