Počátek a koncentrace: společné vlastnictví, kontrola a výkonnost
Hanousek, J. ; Kočenda, E. ; Švejnar, Jan
We analyze the effects of different types and concentration of ownership on performance using a population of firms in a model transition economy after mass privatization. Overall, our results suggest that the expectations and earlier findings of positive effects of privatization on performance were premature, with the effects of many types of ownership being indistinguishable from that of state ownership.

Verification Tightness of Headlamp
Maule, Jiří ; Pernikář, Jiří (referee) ; Osička, Karel (advisor)
The task of my work is to describe and analyse tightness control of front headlights in automotive industry. This work is concerned with theoretical indi-cative allocation according to the light source, development and contruction of headlights in preamble. There is shown the way of disclosing the outflow pres-sure area at loose headlight in next part of this work. It defines the most proba-bly caused reason of untightness with help of Ishikawov diagram. There is also made evaluation of measured values and determined the main cause of un-tightness. At the end there are shown possibilities of statistic´s evaluation of measured values and made changes necesarry for untightness elimination.

Trailer frame VARIANT for transport cabel spools
Buchta, Vladislav ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
Thesis deals with the truck frame VARIANT 252. The main task is to analyze weighting states, setting the values for weigting states. Strength control of the frame by using the Finite Element Method (FEM). And each subsequent frame adjustments based on the results of FEM. Part of this thesis is also the drawing documentation provided a modified frame assembly and each modified components.

Continual helicoidal mixer
Radoš, Pavel ; Malach, František (referee) ; Malášek, Jiří (advisor)
This work contains a proposal for constructions and workings of a worm mixer of clay, lime, cementand fly ash with water for delivery quantity 18 tons per an hour. The introduction describes problems of mixing and mixers in the preparation of building materials. I have mentioned calculation of the main proportions and drive under the relevant norms and self-fortress control of the stresssed parts of mixer. Drawing documentation is worked into the ACad program and contains the configurations of the proposed machinery and detailed subassembly of important parts of worm mixer.

Specific Attributes of the Czech National Football A-Team
Hüblová, Anika ; Malý, Milan (advisor) ; Velinov, Emil (referee)
The aim of this thesis is to analyze specific attributes and contemporary practice in managing of the Czech National Football A-Team and define a scope for its improvement by using general principles of management. It describes basic general terms of management and in details elaborates on the management of the Czech Football A-Team. It is also focused on main management functions and their practical use with the National A-Team. A significant part of the text describes and analyzes the general management principles such as decision-making, planning, organizing and supervision and their application in the control activities of the Czech National Team. At the end of this thesis the specific attributes of the management of the National Football A-Team of the Czech Republic are listed and measures and suggestions how to improve the management process are proposed.

Automatic control for factory building heating
Prudek, Miroslav ; Voldán, Jiří (referee) ; Němec, Zdeněk (advisor)
The graduation thesis is focused on the automatic operating of heating of the production hall of První brněnská strojírnaVelká Bíteš, a.s. The thesis consists of an analysis of present state of the heating technology and solution of the general conception of the automatic operating of the heating. Integrated part of the conception is heat-up of the supply water and drain off of the condensation water from the air heating units. Outcome of this graduation thesis is a design of the algorithm for operating of the regulated system. Remote supervision and control of the regulated system shall be ensured by the visualization setting, which shall be implemented into the station of dispatching centre. The accuracy of the design of the part of regulated system shall be validated as a design of PID regulator with the use of “Matlab” program and it´s module “Simulink”. To set up parameters of the PID regulator, “Ziegler-Nichols” method shall be applied. The objective pay-off period of investments for regulation controlling system is figured out as a part of this thesis as well.

Costs reduction in production of Al-alloy castings
Nováková, Lucie ; Lána, Ivo (referee) ; Roučka, Jaromír (advisor)
This thesis deals with solving the most serious internal defects in castings made of aluminum alloys which are cast in sand molds in Slévárna a modelárna Nové Ransko Ltd. The problem solving contains a description of the problematic castings with the investigation of the structure and phases and subsequent detailed analysis of their production. The Author of this thesis also examines the influence of Fe and Mn on a possible formation of the internal porosity with the help of test meltings with the evaluation of the internal structural change. The Author’s design solution is a close checking of chemical composition with regard to the ratio Mn / Fe present in the alloy, the purchase of Foundry Degassing Unit to reduce gassiness of melted metals and better control of gassiness with the help of the appropriate equipment for the density Dichte index.

Metrological characteristics of electrocardiographs
Brožík, Stanislav ; Hozman, Jiří (advisor) ; Beneš, Jiří (referee)
In measuring of electrical activity of hearts, the control of accurate function of electrocardiograph and elimination of the measurement deviations is essential. This diploma thesis describes the procedure of putting together and use of nine gauging fixture according to international recommendation R 90 (Edition 1990). These devices are directly connected to the tested electrocardiograph. When following the recommended procedure of measurements and equations it is possible to find out if the parameters of electrocardiograph don't exceed the allowed measurement deviations.

Nuclear arms control, regulation and nuclear disarmament
Bříza, Vlastislav ; Ondřej, Jan (advisor) ; Šturma, Pavel (referee) ; Kozák, Kryštof (referee)
The dissertation concludes with the main points of the research and analyses in the above mentioned four pillars and also assesses the status of the efforts for nuclear arms control and nuclear disarmament in its whole history. However, the overall picture is a mixture of successes and failures and suggests that the only way to reach nuclear disarmament in a long way through step-by-step process that would also lead to reaching higher level of world peace and stability. However, even the idea of the world without nuclear weapons has its drawbacks as the dissertation tries to show. Especially with respect to change in the US administration in the early 2009 and its approach to nuclear disarmament, there also still remain many unanswered questions that are left for further research.
