Usage of High Power Inverters in High Voltage Sources
Zemánek, Miroslav ; Janča, Jan (referee) ; Boušek, Jaroslav (referee) ; Patočka, Miroslav (advisor)
This work is concerned with power inverters for alternate high voltage power sources. The theoretical part describes the topology of inverters that can be used in alternate power sources. A model of voltage transformer is described in details to better understand the parasitic effects that are inevitably present in high voltage power sources and, therefore, have to be taken into consideration at the design of high voltage power sources. The work is oriented to problems of alternate high voltage power sources for ozone generators. This is the reason, why the theoretical and, partially, also the experimental part deal with the properties of ozone and its use. The experimental part solves high voltage inverter with capacitive load that is formed by discharge element of an ozone generator. Designed inverter is able to feed the capacitive load with high voltage at very short periods of time from several microseconds up to tens of nanoseconds. In comparison with the length of voltage pulses in common ozone generators, this pulses are more than 100-time shorter. This has a positive effect to silent discharge characteristics.

Sports Centre
Janča, Jan ; Havířová, Zdeňka (referee) ; Lavický, Miloš (advisor)
This Diploma thesis „Sports centre“ was made as a documentation for a building construction. The object of the sports centre is designed for 337 people and consists of two above-ground floors sports hall itself and joined one above-ground floor restaurant. It is detached building. Building is designed in slightly sloping terrain. The sports centre is located on the outskirts of city named Odry, within walking distance of residential buildings. The sports hall is divided into sections for athletes and referees, part for employees and parts for the public. The restaurant has own entrance from the western side of the building and is functionally connected to sports hall. The restaurant is further divided into units for the public and for the staff. The construction system of the sports hall is made of a prefabricated skeletal system based on baseplaces and a filling wall on the strip foundations, the restaurant is only bricked and based on the base on the strip foundations.

Chytrá zásuvka s podporou měření proudů
Janča, Jan
This work is aimed at creating a prototype of a smart socket that is able to measure the current power consumption and remotely switch on an individual socket. The prototype itself is built on an Arduino microcontroller and Arduino compatible components. Subsequently, all components are placed in a 3D printed box. The box is made of self-extinguishing material. A web interface is created for controlling the box, in which the current electricity consumption is found. This data is also stored on an SD card in a text file for future reference. The program for the Arduino is written in C++ and for the web interface using HTML.

History and use of self-defense
Janča, Jakub ; Kašpar, Ladislav (advisor) ; Dlouhý, Martin (referee)
Title: History and use of self-defense Abstract: This bachelor thesis deals with the history and development of self-defense techniques in martial arts and combat sports in the world, interactions, and the factors that influence the development and the course of self-defense situation from the technical conditions to compliance with statutory rules to maintain the status of the self-defense, permitted by law (legal) action. In the thesis there is the exercise training of self-defense techniques and basic training in martial arts elements applied in self-defense suggested. The appropriate specialized literature and websites dealing with applicability of various pieces of knowledge to the problems of self-defense were used as a source of information. The solving lead to the conclusion that the fighting skills have accompanied mankind since time immemorial, and have developed with it as well. The training in self-defense systems can become the way to personal self-improvement. Key words: history, self-defense, combatives, tactics, technique, psychology
