Turn - over positioning table
Mareček, Vojtěch ; Dokoupil, Vladimír (referee) ; Foller, Bronislav (advisor)
This diploma thesis deals with projection and general design of rotary indexing table for dedicated machine tools. The major attention is given to substitution of hydraulic drive table by table driven by servomotor, namely double axis its positions in vertical and horizontal directions. The total configuration of rotary table is solved as a construction kit, user can used any servomotor and additive gearbox. The work is concentrated to the optimization of table construction for this new designed conception. The positioning and fixing of table plate is solved by couple of Hirth couplings with central hydraulic motor. The computational part of work includes calculations of dynamic of rotary motion of the table and hydraulic system. All important screw connection, gear wheels and Hirth couplings were verified by calculations. Also working lifetime of bearings and strength deformation of major constructional sections of rotary table verification were controlled. Inherent part of work is security analysis, economics analysis, patent search and analysis of construction identity. Presented work contains three-dimensional model, drawing documentation of both variants of configurations and production drawing of major section parts of rotary table.

The Role of the European Union in the Normalisation of Relations between Serbia and Kosovo
Mareček, Vojtěch ; Dubský, Zbyněk (advisor) ; Veselý, Zdeněk (referee)
The main topic of this bachelor s thesis is the role of the European Union in the political development of Serbia and Kosovo, starting from the Allied Force operation in 1999 and ending with the current process of normalization of relations between the two states. The thesis is divided into three chapters. First chapter deals with the concept of power in international relations and the work of Joseph Nye who introduced the concept of soft power. Second chapter introduces the topic of relations between Serbs and Kosovar Albanians from the end of World War II until the climax of the tension between both ethnical groups before the war in Kosovo in 1998. The third and main chapter of this thesis identifies and analyses tools which are used by the EU to influence the development in Western Balkans. Furthermore, based on theoretical findings in the first chapter, it attempts to determine whether the tools the EU uses to influence the development in Serbia and Kosovo are based on soft or hard power.
