This is part of the social program of the 23rd Euromicro Conference on Real-Time Systems http://www.cister.isep.ipp.pt/ECRTS11/. It is intended for partners and family members accompanying conference/workshops attendees. While the offer is free of charge, some entry fees may occur and the consumption in cafés and restaurants is the individual responsibility. The program of the partner program can be found on the conference website: http://www.cister.isep.ipp.pt/ecrts11/porto/ We ask for registration to aid our preparation, however, changes are possible even after the form has been submitted and we kindly ask you to inform us about a change in your plans. Opposed to this offer, the social program in the evenings is separate to this and subject to tickets to be purchased via the conference website.
