Preface This report provides a summary of the activities of the Computer Science Department at RWTH Aachen University for the extended period from January 2007 to September 2008. The reason for this unconventional reporting period is that we decided to move the publishing date of the department’s annual report from the Computer Science Summer Festival to the “Tag der Informatik”, our main public event and graduation ceremony which traditionally takes place on the first Friday in December. Consequently, we cover a longer period in this report before we will continue to report on the academic year in the future issues. In this booklet you will find ample information not only about our research and teaching activities, but also about social life and important developments in the department. The first part, Faculty Life, looks back on events like the “Tag der Informatik 2007” or “Bright Brains in Computer Science”, which received considerable public attention. It also introduces the staggering number of six new colleagues in the faculty, Erika Ábrahám, Paolo Bientinesi, James Gross, Thorsten Kuhlen, Bastian Leibe, and Ulrike Meyer. Part two, Teaching, presents the different study programs offered by the Computer Science Department and the courses taught. In the third part, Research, our research groups report on their many projects. The forth part, Central Services, introduces three indispensable organisational entities of the department: the System Administration Group, the Computer Science Library, and the “Fachschaft”, our students’ organisation. Finally, there is a part on joint projects carried out by different groups of the department together with partners from other disciplines within RWTH Aachen University or from outside organizations. Although you will find detailed coverage on all the individual topics in this report and even though we risk to leave out some of the important achievements, we still want to list a number of selected highlights in the following to spark the interest of the reader. • The success of the Institutional Strategy „RWTH 2020: Meeting Global Challenges“ of our university in the Excellence Initiative of the German federal and state governments in 2007 had enormous impact on the Computer Science Department. Several members of the faculty contributed to the various measures in the proposal. Considering all the different major projects now being funded at RWTH Aachen by the Excellence Initiative, there is hardly a single one where Computer Scientists are not involved. The major involvement certainly being in the Excellence Cluster “Ultra High-speed Information and Communication” (UMIC) which gained considerable momentum in this reporting period. • As a result of these activities, several new faculty positions could be established and filled. In UMIC, Ulrike Meyer accepted a professorship for IT Security, James Gross and Bastian Leibe became Junior-Professors for Mobile Network Performance and for Mobile Multimedia Processing, respectively. Two other strands of the Excellence Initiative, the measure “Strengthening the Natural Sciences” and the Graduate School “Aachen Institute of Advanced Study in Computational Engineering Science” provided two further juniorprofessorships which were taken by Erika Ábrahám (Theory of Hybrid Systems) and Paolo Bientinesi (Algorithm Oriented Code Generation for High-Performance Architectures). Finally, Torsten Kuhlen was appointed a professor for Virtual Reality. • The number of freshmen increased again to 300. All in all, the faculty is still responsible for slightly more than 2000 Computer Science students. The number of graduates in all Computer Science programs together is roughly 200 per year and some 20 computer scientists graduate with a Ph.D. from our department. • The State Ministry for Innovation, Science, Research, and Technology approved the establishment of the B-IT Research School in Applied Informatics, which is 1
