Evaluation of the fillet weld geometry on process parameters for laser welding of stainless steel
Polášek, Marek ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
The present thesis deals with welding of samples to examine the resulting geometry of the weld in dependence on process parameters of the laser. Welding was carried out without additional material using a fibre laser. The material used was stainless steel ČSN EN 17 241. The values of regression coefficients of the resulting graphs show that the changes in the weld geometry - width and depth - vary quite linearly depending on the welding performance. Especially the weld depth is a common requirement in technical practice; the measured results of the experiment can be used to set the process parameters to achieve the desired depth of weld. Some welds exhibit weld defects such as porosity caused by formation of the keyhole due to a large dynamics of the process. The technical-economic evaluation offers a price estimate for one meter of weld for each welding speed used.

Project of production transfer
Polášek, Marek ; Prostredník, Daniel (referee) ; Fiala, Alois (advisor)
The present Master thesis deals with a transfer of the production process from Asia to Europe. The aim is to provide a life cycle of the project, its phases and the respective actions, an analysis of the risks associated with this transfer, a successful start-up of series production and the design of the internal audit as a standard of control for setting a stable and quality manufacture of the product in the Brno production plant.

Torsional Damper for In-line 5-cylinder Engine
Polášek, Michal ; Svída, David (referee) ; Dundálek, Radim (advisor)
In this diploma thesis is created a cranktrain model in the MBS system ADAMS Engine. The thesis defines basic parameters and proportions of the torsional damper for in-line 5-cylinder engine. This thesis also puts mind to calculation of torsional vibration. In the MBS system ADAMS Engine is demonstrated affect of torsional damper on the torsional vibration of the crankshaft.

UKIP and FPÖ, comparative analysis of party-based euroscepticism
Nováčková, Kateřina ; Polášek, Martin (advisor) ; Bíba, Jan (referee)
The focus of the bachelor thesis is Euroscepticism and radical right parties. At first, the thesis describes the origins and roots of contemporary Euroscepticism, the next step is to present the main theoretical approaches. Based on that, the theoretical framework will be introduced. The aim is to define to which type of Euroscepticism belong United Kingdom Independence Party and Freedom Party of Austria and compare their manifestos during the period 2009-2014.
