Preface It is a long standing tradition that the Computer Science Department at RWTH Aachen University provides a detailed yearly report on its broad and many activities. This booklet does that for the academic year of October 2009 to September 2010. You will find ample information not only about our research and teaching activities and our scientific successes, but also about social life and important developments in the department. We, as the current and past speaker of the Computer Science Department, are happy to observe that we are able, again, to report on a very successful year. At the beginning of this reporting period, our first Master students in Computer Science started their studies. We have had Master students in our international programs before, but now we successfully completed the transition of our main study program from the former Diplom to the new Bachelor/Master system. We expect to congratulate the first MSc Computer Science graduates in 2011 when the next report will be published. During the year we initiated two major activities to attract school students for computer science. In the so-called Ringvorlesung we offered 15 talks with the objective to communicate the fascination of computer science to a non-expert auditorium. These talks attracted a rather large number of school students so that we decided to continue the series in upcoming years. The newly established Informatik Schülerlabor invites students from grammar to high-school to learn about computer science methods and applications. The lab offers various gateways into the fascinating world of computer science. It is run by the computer-supported learning research group headed by Prof. Ulrik Schroeder. A major event in this year’s department life was the retirement of Prof. Otto Spaniol in August this year. To mark this occasion, a two day scientific colloquium was held in his honor on September 27 and 28. Several of his former students who are now Professors at other universities and further renowned guests presented scientific and other kinds of highlights. The strong impact of Prof. Spaniol’s work on our department and the communication and distributed systems community was enlightened by the event in an impressive manner. The high numbers of offers from other universities to colleagues of the past two years continued. In the reporting period, we had to beat enticements to three of our colleagues. We were successful in all three cases. In the last twelve months, our faculty colleagues and researchers received numerous awards and distinctions. It is impossible to list all of them here. Therefore we will mention only the most important ones, omitting for example the numerous best paper awards and conference chair activities: • Prof. Matthias Jarke was elected head of the Fraunhofer ICT Group, Europe’s largest combined research unit for information and communication technology, and member of the Fraunhofer Society executive committee, starting January 1, 2010. • Prof. Nagl was appointed as Vice-Speaker of the Accreditation Committee of the European Quality Assurance Network for Informatics Education (EQANIE). After this list of appetizers, we would like to invite you to browse through the following pages of this report where many more accounts of our activities can be found. You are also invited to contact the respective members of the department, if you have a deeper interest in one of the topics or if you want to share your feedback with us. Finally, we thank Kai Jakobs for compiling this report. Aachen, November 2010 Berthold Vöcking Speaker, Computer Science Department Stefan Kowalewski Past-Speaker 1
