List of Practical Courses


The lectures in the Bachelor's and Master's programs are accompanied by an experimental part. The theoretical backgrounds and knowledge acquired during the theoretical courses are directly used and transferred to measurement tasks. Essential engineering and scientific approaches and the required evaluation processes are practiced directly. Small groups enable detailed discussion and the presentation of the gained results, which is another important aspect of the requirements in the engineering work routine.
