Generation of Voltage Wave by Impulse Generator
Poloni, Miroslav ; Krbal, Michal (referee) ; Pelikán, Luděk (advisor)
The presented bachelor thesis deals with the problems and functions of impulse voltage generators. The theoretical part describes the functions and various connections of the impulse generator, types of impulse voltage, tests and test procedures. In the practical part of the work, theoretical knowledge in the form of simulations was verified. The simulations were performed in the LTspice program from Linear Technology, where the impulse generator model was made. Simulations were then performed on the given model of the shock generator, from simpler ones such as the dependence of the size of the load capacity to the inductance connected in parallel. The results of all simulations should bring benefits and ease in real shock generator tests

Welding technology of turbine rotors
Pivoňka, Vít ; Kubíček, Jaroslav (referee) ; Daněk, Ladislav (advisor)
The paper deals with all the possibilities which can be used to weld the rotors of turbines, both the root and the filler welding. All these methods are thoroughly analyzed and their properties are described, especially the size of the heat input by welding of rotors of turbines. Further in this work is described the organization of the structure by means of a metallographic survey and a test of welds and materials, which are performed to check whether the material and the welding method are suitable for welding of rotors of turbines. In the experimental part are described all welds made by different welding parameters, one of these welds is chosen to achieve the best welding of the weld root. This weld is further investigated for hardness and change of microstructure after welding.

Analysis of precast walls made of plain concrete and lightly reinforced concrete
Janda, Miloslav ; Lavický, Miloš (referee) ; prof. ing. Jan L. Vítek, CSc. (referee) ; Zich, Miloš (advisor)
This dissertation analyses precast walls made of plain concrete and lightly reinforced concrete. The main focus is on evaluating the concrete and the reinforcement of precast concrete wall panels in relation to manufacturing, handling, and final phases. The dynamic load component of panels during handling was measured in controlled tests. Shrinkage measurement was implemented during the maturing process of the concrete used for panel manufacturing. The value of cohesion was observed between the reinforcement and the concrete that had matured for 20 hours. It was also looked at the value of adhesive strength between the panel surface and the casting table. The experimental study checked the panel strain during removal from the casting table, the panel compression during a truck ride over an obstacle, and the tension in the carriage strap during panel transportation to the building site. Mathematical formulas were drawn up to validate the concrete and reinforcement of wall panels made of lightly reinforced concrete. Those mathematical formulas were applied in a specific panel wall design and the results were verified by nonlinear numerical models.

Hints for Inorganic Chemistry Tests E-learning Study Materials Processing
Straka, Radek ; Kábelová, Božena (referee) ; Richtera, Lukáš (advisor)
E-learning is an educational way which uses multimedia and communication technologies for making, transferring and offering materials for studying. The aim of this bachelor thesis is making educational materials using the form of hints for inorganic chemistry tests. The first year students come into the contact with these tests compulsorily in the Inorganic chemistry laboratories II on Faculty of chemistry of Brno University of technology. The thesis contains six parts. First five parts are set to general view of e-learning and last sixth part obtains chosen hints for inorganic chemistry tests. Next hints are appended on CD for its considerable size (cca 600 hints).
