Please note that many of the below publications are subject to copyright restrictions but you are free to use such publications for personal use. I keep only the most recent version of each paper in the below list and thus a conference paper can disappear and come back in the form of 'unpublished' or 'journal publication'. Futhermore some of the publications are slightly different from the published version and in need of an official version please go to the indicated source.

If cannot find what you want do not hesitate to contact me by email: username 'johanh' then the at sign followed by domain ''.
