Studying Business Informatics at the University of Wismar. Here are some of my projects and presentations. Documentation is in PDF format (through LaTeX). Personal data is removed. Given are the end-dates of the projects.

Integration of QMF and OLAP, 09/2005

• Report of my internship at IBM Silicon Valley Lab back in 2001. It talks about an instance of the QMF/OLAP integration.
• Document (388 KB)

Data Mining: Analyses of Car Accident Data, 01/2005

• The main goal was to predict the "heaviness" of potential car accidents based on run-time data. The best results were achieved using WEKA and DB2. Furthermore, possible ways for improvements are shown.
• 4 person project with me as project leader
• Document (707 KB), Slides (111 KB), Homepage

Software Technology: Re-design of a Museum's Multimedia Presentation, 12/2004

• The Technische Landesmuseum Schwerin is a technology museum. Several touchscreen terminals run a multimedia presentation as e-learning application. We optimized the growen presentation in terms of usability, speed, extensibility, and integrated new content. At Steigenberger Hotel Wismar we presented the new version to authorities and the interested public.
• 2 person project, equal work distribution
• Press release, as printed in newspapers

Internship at IBM Silicon Valley Lab, 10/2004

• Presentation of my internship at IBM Silicon Valley Lab and my life in the USA
• Slides (1.3 MB)

Cryptography: Modern Block Ciphers, 09/2004

• A paper about "Modern Block Ciphers": DES, AES (Rijndael) etc. + some basics in math
• Document (565 KB)

Knowledge Extraction Using Neural Networks, 06/2004

• Replaying the Data Mining Cup 2002, originally an international contest with 120 submissions. Our solution finding was restricted to Neural Networks. Using SNNS + batchman and Perl, we analyzed more than 100'000 network results and achieved a very good outcome: The results would have put us in second place at DMC.
• 4 person project, I was technical leader.
• Document (739 KB), Slides (469 KB), Homepage (incl. data)
• Errata: It should be 'Lernzyklen' (learning cycles) instead of 'Lernschritte' (learning steps).

Mobile Agents: Inverted Pendulum with Lego Robots, 04/2004

• The goal was to build and program a stick-balancing Mindstorm robot. We achieved an extremely compact solution with light sensors and without any Fuzzy Logic or goniometry. Spectators demonstrated high interest when we presented it at the Open Day of the University. The video shows the robot's functionality.
• 2 person project, I was mainly responsible for the software part.
• Document (71 KB), Homepage (incl. video and NQC source)
