Stroke mechanism of bridge crane
Jirásek, Jiří ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis deals with the design of the lifting mechanism of the crane cat, for a bridge storage crane with a load capacity of 8,000 kg. The thesis contains a critical research of similar existing solutions and the selection of the appropriate concept. The design includes calculations of the basic parameters of the stroke, and based on them selects appropriate rope, pulleys, and design of the rope drum. Furthermore, there are calculated and selected suitable components of the stroke mechanism such as electric motor, clutch, brake and gearbox. The last part deals with the design of the bearing, the drum pin and the calculation of the shaft key. The output of the work is the technical drawing of the whole assembly of the mechanism and the welding subassembly of the rope drum.

Design of automatic clamping device for CNC milling machine
Jirásek, Jiří ; Holub, Michal (referee) ; Tůma, Jiří (advisor)
This work is focused on the design and construction of a device for automatic replacement of workpieces for CNC milling machines. The thesis contains research in the field of automatic replacement of workpieces. The design itself can be divided into two parts. The first part is the selection of a universal clamping platform and the design of a technological pallet. The second part is the design and construction of the clamping device. First, different design variants are proposed.. These variants are then evaluated by multi-criteria analysis, based on which the most suitable variant is chosen. This is followed by the selection of suitable components for the assembly of the universal clamping platform and the construction of the technological pallet. The main part of the work is the structural design of the pneumatic wedge vice, including the necessary calculations and design of individual components. The output is technical drawings of chosen components and a technical drawing and CAD model of the assembly.

Direct democracy in the Czech republic
Pechanec, Pavel ; Pavlíček, Václav (advisor) ; Sládeček, Vladimír (referee) ; Jirásek, Jiří (referee)
The main topic of the presented dissertation is the direct democracy and its legal institutions incorporated in the legal order of the Czech Republic. The first part of the dissertation is dedicated to the democracy as a government form and to the historical breakthroughs in its development. The key historical milestones on the way from despotism, through the Athen democracy, followed by long period of democratic deficit, up to the renaissance of democracy during bloody revolutions are mentioned as well. Further attention is paid to the representative and direct democracy, their mutual compatibility and definition of basic elements within both conceptions. The second part is referred to the direct democracy legal institutions in the legal order of the Czech Republic. Historical commentary is followed by general interpretation de lege lata. The direct democracy legal institutions are pursued from the year 1918 to the present. Merely commentary on the petition law goes deeper into history. Within recent legislation it is being proceeded from larger to smaller (a maiori ad minus). Our attention is in the first instance focused on the direct democracy legal institutions in the constitutional order of the Czech republic. Subsequently, their implementation in so called "common legislation" is described,...

Compatriots and the so-called compatriots law in Central Europe
Halász, Ivan ; Pavlíček, Václav (advisor) ; Jirásek, Jiří (referee) ; Mikule, Leoš (referee)
1 Compatriots and the so-called compatriots laws in Central Europe Abstract Dr. Ivan Halász The main goal of this publication is to present the development of the compatriots issue in Central Europe. In this meaning Central Europe includes the so-called Visegrad part of this region: the territory of the Czech Republic, Hungary, Poland and Slovakia. The thesis is dealing with the Czech, Hungarian, Polish and Slovak compatriots living abroad and with their relationships with kin-states. The book is not covering all aspects of this complicated problem, but it is dealing only with the legal and administrative aspects of the issue of compatriots. It analyses the process of establishing the legislation of compatriots and also its development. The main goal of this legislation is the kin- state support for the compatriots communities living abroad. The dissertation focusis on the compatriots issue from the institutional point of view (which institutions deal with this problem and who is representing their interests in the kin-state?) Naturally, the introduction starts with terminology clarifications. Who is the compatriot, what are the differencies between the compatriots, emigrants, expatriots etc. How can we interpret this notion in the Czech, Hungarian, Polish and Slovak national context? What are the...
