We celebrated the 5th SEET workshop in beautiful Sesimbra, Portugal. Sadly all papers could not be accepted, finally thirty two papers interesting works of research were presented. The participants got time to interact with participants and work with their coauthors. Everyone agreed that next years SEET workshop will be repeated in Sesimbra and Luis Santos Pinto (U. Lausanne) offered to organize it. We are sure it will be equally successful and hope to attract even more interesting papers.
