Race Car Passive Safety
Schultz, Richard ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This work presents all kinds of passive safety currently used in motorsport. It deals with their development, use, materials from which the element is made, the actual production and testing, irrespective of the particular category of motorsport. I tried to clarify the various elements in terms of function, what lies in their uniqueness and thus differ from those used for passive safety in passenger cars. Although the job title is Race cars passive safety, I mentioned in it about driver protective clothing as one of the elements to protect his life in case of emergency. Gradually, I deal with various aspects of security from leading to an accident as the first show its functionality to features such as fireproof clothing, seeking to mitigate the consequences of an accident.

Potential of ABC in Primus CE's logistics process
Hejtmánek, Petr ; Stránský, Jakub (advisor) ; Wagner, Jaroslav (referee)
This work focuses on application of Activity based costing method in Primus CE. Within the practical part of the thesis, analysis of selected part of logistics process in the company is performed and activities within the process are mapped and valued. The thesis describes individual steps of valuation. Firstly activities for valuation are defined. In second step, cost-pool related to defined activities is identified. Following this step cost-pool is divided into sub-cost-pools based various cost-drivers which are likely to be common for activities in the groups. Selection of cost drivers is covered and reasoning is provided in the thesis. In the last step, cost of each activity is calculated. The summary of the work includes findings from the process of creating this model as well as findings resulting from valuation itself.
