All the DOS-software and most of the JAVA-software on my website are hobby projects and have little or nothing to do with my actual work. During my PhD. I worked on the structure analysis of quasicrystals under the supervision of Dr.Akiji Yamamoto. The title of my thesis is Application of the five-dimensional maximum entropy method to the structure refinement of decagonal Al-Mn-Pd quasicrystals. Our work deals with the structure solution of quasicrystals on the basis of single (quasi)crystal X-ray data. For this we use the higher-dimensional space approach. Quasicrystals which are aperiodic in three-dimensional space can be described as periodic "crystals" in a space of usually five or six dimensions. This means that we actually solve the higher-dimensional periodic structure, from which the real three-dimensional structure is obtained by some appropriate section algorithm. Before coming to the US I was a STA Fellow (Science and Technology Agency) at NIRIM doing a postdoctorate. In cooperation with Dr.Akiji Yamamoto I was working on various software packages for applying an imaging plate Weissenberg camera to the data collection on quasicrystals (see my JAVA applications page)
On September 11, 2002 I regained perfect vision through LASIK eye-surgery at the LasikPlus Vision Center in San Jose / California ( http://www.lasikplus.com ). The procedure was performed by Dr. George V. Simon, who I highly recommend. The whole operation took about 15 minutes for both eyes. Modern Bausch-Lomb excimer lasers were used, which are able to treat larger areas and which use dancing-spot technology, which is similar to dithering in printers in that a smoother surface of the treated area is achieved.
