Numerical Modelling of Counter Flow in T-Junction
Míčka, Martin ; Šperka, Oldřich (referee) ; Štigler, Jaroslav (advisor)
The main objective of this master thesis is to implement the numerical modelling of the confluence of streams in the Tee-junction using Fluent CFD software. Modelling is carried out for different ratios of flow rates in steady flow. Calculations are evaluated, using a new mathematical model, by curves of loss coefficients. Furthermore, the influence of the selected type of the mesh in geometry on results from numerical modelling of flow is examined. Geometry of the Tee-junction is created in Gambit software. Finally, the results obtained from numerical modelling are confronted with results from an experiment.

Description of machine tool frames.
Míčka, Martin ; Matějka, Petr (referee) ; Blecha, Petr (advisor)
This work describes the machine tool frames via background research. There are basic requirements for the frames included in this work. It is focusing especially on static and dynamic rigidity. Thereinafter you can find in my work all the ways of making the frames and also the materials which are used during their production. Last but not least I am presenting some examples of constructions single parts of the frame and all the ways of their attachment to the ground.

Threat under the influence of addictive substance
Micka, Martin ; Říha, Jiří (advisor) ; Vokoun, Rudolf (referee)
EN: The misdemeanor of endangering under the influence of addictive substance is one of the most frequently occurring criminal offenses that the Czech society encounters. I have divided my thesis into nine chapters. The first chapter deals with elements of the criminal offense under the influence of addictive substance as divided by legal theory. The second chapter describes the issue of the unlawfulness of the deed. The third chapter deals with an analysis of qualifying circumstances that legislature provided in the second paragraph of the misdemeanor of endangerment under the influence of drugs. The fourth chapter describes the issue and the conditions of participation of persons other than the principal perpetrator of the deed. The sixth chapter deals with the most common criminal offenses that occur along with the abovementioned misdemeanor. The seventh chapter is devoted to the new phenomenon of proving a condition that excludes competence in cases of influencing other addictive substance. In the eighth chapter I focus on the issue of showing of various types of sentences with regard to current practice in relation to sentencing for the deed in question under Section 274 of the Criminal Code. The ninth chapter describes various forms of so-called special methods of proceedings which are used in the...
