A proposal and manufacturing of temporary dental restoration
Jiroušek, Jan ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This bachelor thesis deals with manufacturing of temporary dental restoration. Theoretical part contains an overview of types of dental restorations and their division, Furthermore it states important properties and division of the dental materials used nowadays. The next point of theoretical part is an overview of the technologies of dental restorations manufacturing used at present. Practical part is aimed at manufacturing of temporary dental restoration by using the digitization by intraoral scanning, design of restoration in CAD software and CAD/CAM manufacturing. The thesis is concluded with discussion comprising a summary and evaluation of the results of single steps from practical part.

Design of Stirling Engine Operating at Low Temperature Difference
Gavač, Adam ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
The aim of this study is to acquaint the reader with the Stirling engine, which is one of the possible alternatives to generally known combustion engine. The theoretical part has three major purposes: First is to describe thermodynamics of the Stirling cycle in the range that is essential for comprehension of the engine`s operating principle. Second is to mathematicaly derivate expression for the efficiency of the ideal Stirling cycle. Third is to discuss each of the essential parts of the device. Concepts acquired in the theoretical part were employed to design a digital model in the parametric modeler Autodesk Inventor. Parts were manufactured by a combination of typical and progressive technologies. Engine was assembled and tested afterwards.
