My advanture with PhD studies has begun. In October, that is, first month of my PhD studies I have done literature research. I have read a lot of papers related to grain boundaries concerning diffrent methods of boundary parametrizations, techniques of representing misorientations, tools for recognizing various characteristic types of GBs. I have written some first lines of source code of my software tool, which, in the future, will be able to perform some analysis of a single boundary and to carry out some statistical analysis of large data sets of grain boundaries. I started with functions for conversion between various rotation representations.
