The diploma thesis deals with the issue of a quality assessment of a bore of shotgun barrels. There are mentioned both definitions of a quality shotgun barrel and also a quality of shotgun barrel bore. In conclusion, there are presented particular proposals for evaluation of parameters of surface texture of forged shotgun barrel blanks.

The diploma thesis focuses especially on a design of a way for evaluating roughness in road profile, which affects driving characteristics of a car and a ride. In the theoretical part of the thesis are mentioned the most used methods and tools for road roughness analysis in the world. For the purposes of this thesis an experimental measuring were undertaken in order to obtain data for the own design of a road profile analysing system.
