Technology of Selective Catalytic Reduction for Passenger Cars
Jurík, Juraj ; Janoušek, Michal (referee) ; Dundálek, Radim (advisor)
This bachelor’s thesis describes the selective catalytic reduction technology. It concerned of reducing nitrogen oxides in diesel engines. It describes components of the technology, their function and location in system. in first chapter there are described harmful substances of exhaust gas in connection with this technology. Second chapter contains description of emission standards. Next chapters are describing selective catalytic reduction and solutions of some manufacturers.

Torsional Vibration of Three Cylinder Engine with Balancing Shaft
Jurík, Juraj ; Hrdlička, Zdeněk (referee) ; Dundálek, Radim (advisor)
Content of this master thesis is analysis of torsional vibration of the three cylinder engine with balancing shaft. In theoretical part of the thesis the kinematic and dynamic description of the cranktrain mechanism is included. The formation of unbalancing of the engine and methods of balancing are described in the theoretical part as well. In practical part of the thesis the analytical calculation of torsional vibration is provided. Simulation of the engine model in multibody software Adams/Engine was used as the other way of torsional vibration analysis. In the result part of the thesis the comparison of the both way of analysis were discussed. Last step of the thesis was design proposal of the torsional vibration damper done by the analytical calculation.

Current state and future perspectives of Tatra National Park from the viewpoint of stakeholders
Jurík, Juraj ; Rynda, Ivan (advisor) ; Hošek, Michael (referee)
The main research objectives of this master thesis are the stakeholders and their opinions on the management of Tatra National Park in Slovakia. There are many stakeholders in the national park and each one has different interests. The objective is to find a compromise between the protection of the nature and the degree to which the national park would be used for human purposes. As a result, the area would also be managed in accordance with the national legislation and international guidelines (IUCN) category II and also provide human society with a variety of benefits. The goal of the thesis is to find out how this management will look like in practice. Qualitative interviews were used in order to obtain the opinions of the main stakeholders. Framework analysis has been applied to analyse all the interviews. Key words: stakeholders, protected areas, national parks, management, IUCN categories, national legislation, tourism, nature protection, sustainable development, framework analysis
