Hi all! Today, I have set online my doctoral thesis (dissertation, written in german). It is entitled "Beitr"age zur Auswertung und Versuchsplanung in der R"ontgenpulverdiffraktometrie", which I translate to "Contributions to evaluation and experimental design in the fields of X-ray powder diffractometry". It dates back to 1984. There are the roots of BGMN and some of the basics. See http://www.bgmn.de/thesis.html Thank you for your attention! J"org Bergmann [EMAIL PROTECTED]
