gzipped Postscript
(double-sided, 147 pages, 620 kB)
or in
PDF (1.4 MB) format. You can also
download the same in single line spacing (118 pages)
in

Have a look at some phase-space
portraits of CRZ and DMS systems.
Noise evolution
in a periodically stationary dispersion-managed soliton (DMS) system.
In 1998, I received a master's degree in physics from the
Technical University of
Berlin , Germany. My diploma thesis concerned
fluctuating lipid membranes. Download the thesis
here (written in English, PDF file, 750 kB).
From Sep. 94 thru Sep. 95, I have been working at the
ZIB
(Konrad-Zuse-Zentrum) Berlin in scientific visualization.
