Materials Used for Cutting Tools for Metal Machining
Tomek, Lukáš ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
This thesis deals with cutting materials used for the production of inserts and tools for ma-chining. The aim of this thesis is to describe the various materials used in machining, their basic characteristics, composition and production. The work also includes a description of profiles of leading world producers of cutting tools. On the example of the designed shaft is made application of turning tools needed for its machining and short description of its production with a graphic demonstration. The final part is devoted to the evaluation of the turning in terms of used resources depending on the cost,productiontime and subsequent recycling of end-of-life instruments.

Financial Markets Comovements in Northern Europe
Tomek, Lukáš ; Čech, František (advisor) ; Brož, Václav (referee)
In this bachelor thesis, we study conditional correlation of various sector in- dices on the stock markets in Northern Europe, namely in Stockholm, Helsinki, Copenhagen and composite indices for Baltic countries. To model conditional correlations, we employ DCC-GARCH framework estimated by maximum like- lihood estimator. Validation of estimated models is based on residuals. We discovered that there is low level of correlation between Nordic and Baltic coun- tries and that some sectors exhibits very high level of correlation, while other tends to have correlation close to zero or even negative for some time peri- ods. Moreover, we observe that some industries have very persistent correlation structure, while others tends to react to the price shocks drastically. 1
