This proceedings is a collection of the extended abstracts of the lectures of the 6th Ph.D. Mini-Symposium held at the Department of Measurement and Information Systems (former Department of Measurement and Instrument Engineering) of the Technical University of Budapest. The purpose of the Mini-Symposium is to give an opportunity the Ph.D. Students of our department to present a summary of their work done in the last year.

The lectures reflect partly the scientific fields of the students, but we think that an insight into the research and development activity of the department is also given by these contributions. Traditionally our activity was focused on measurement and instrumentation but the area has slowly changed during the last few years, new areas mainly connected to embedded information systems are now in our scope of interest as well. Both theoretical and practical aspects are treated.

The papers of this proceedings are sorted into five main groups. These are Instrumentation and Measurement technology, Artificial Intelligence and Nonlinear Systems, Fault Tolerant Systems, Information Systems, Cellular Neural Networks. The lectures are at different levels: some of them present the very first results of a research, because the first year students have been working on their fields only for half a year. The second and third year students are more experienced and have more results of their work.

Some of the papers reflect the scientific cooperation between the Department and the Computer and Automation Research Institute, Hungarian Academy of Sciences. Some Ph.D works are carried out partly within scope of cooperation between our Department and some international research institutes, namely at the Vrije Universiteit Brussel, University of Erlangen, CNUCE-CNR Pisa, MID GmbH, Ecole National Superieure de Telecommunications de Bretagne, University College Dublin. Many Ph.D. Students had spent a longer research period at these universities.

We hope that similarly to the previous five years, this Ph.D. Mini-Symposium also will be useful for both the lecturers and the audience.
