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.

Application of Fused Deposition Modelling Method to Production of Planetary Mechanism Model
Kudláčová, Barbora ; Kolář, Ladislav (referee) ; Sedlák, Josef (advisor)
This thesis aims to deal with designing and construction of the planetary mechanisms mod-el with using the technology of Rapid Prototyping. Virtual model was designed by para-metric program SolidWorks 2013 and produced by 3D printer called Dimension uPrint, which uses Fused Deposition Modeling for the production. The thesis also includes the description of the planetary mechanism especially from theoretical, practical and also construction knowledge. The thesis contains the description of Fused Deposition Modeling too. The model of planetary mechanism is using as an educational tool especially for students of BUT Faculty of Mechanical Engineering in the subject Kinematics.

HSS milling cutters deposited by nanocomposite coatings
Ludvík, Radek ; Kolář, Ladislav (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis deals with nanocomposite coatings deposited on cutting tools of high speed steel. The paper describes the fundamentals of milling, tools for milling and their division and clamping. Gradually, there are analyzed problems of high speed steels (their classification, marking, properties and uses, chemical composition and heat treatment). Then there is described the main characteristics of coating methods (division of coatings into generations, surface preparation before the coating and PVD and CVD methods). The last part of the thesis focuses on the properties of nanocomposite materials and to companies dealing with their application to the high-speed steel.
