Generators for renewable energy
Prokop, Jan ; Macháček, Jan (referee) ; Baxant, Petr (advisor)
The bachelor thesis deals with the topic of generators, which will use alternative sources of energy instead of fossil fuels. The work is focusing on mechanical energy conversion. Introductory part of the text summarizes the requirements on the generator, properties and parameters of appliances, which will be connected to the generator, and finally the selection of suitable alternative fuels. Main part describes the process of a prototype realization. Individual parts of the device have been manufactured from a simplified technical documentation and sketches in the machine shops of the Secondary School of Electrotechnical Engineering on Trnkova street, and from these parts a functional generator prototype has been assembled. This prototype consists of two separate parts: a propulsion unit and an alternator with accessories, including appliances. On this prototype an efficiency measurement has also been carried out. Furthermore, the work includes animations of device functions created in modeling program SolidWorks 2012. Prototypes are based on a known principle of a steam engine and, at the request of the above-mentioned school, have been adapter into a visual teaching aid. The advantage of those prototypes lies in their inexpensive and simple construction, which utilizes commonly available materials. The device works on maintenance-free principle, there is only the necessity of occasional greasing for a fluent running. In conclusion are briefly reviewed the investment and operating costs of the generator.

Analysis of effects of short-circuit current in switchgear cabinet
Prokop, Jan ; Bušov, Bohuslav (referee) ; Valenta, Jiří (advisor)
The work is focusing on dynamic effects of short-circuit currents, more precisely dynamic effects of short-circuit currents on switchgear cabinet (terminal box). The work was designated to a concrete construction type of two switchgear cabinets located on rotating machines via company Siemens Electric Machines Drásov s.r.o.. The switchgear cabinets are designed for non-explosive environment where the air is used as an insulating medium. The task was to determine how the device will behave during the three-phase short-circuit and three-phase short-circuit with earth/ground connection. The following programs were used for the calculations and simulations: Ansoft Maxwell 16.0, Ansoft Maxwell 2015 and ANSYS Workbench 16.0. By using these programs the effects of forces which acts on current paths in cabinet caused by the passage of short-circuit current were simulated, statically and also dynamically. Further the effects of pressure acting on cabinet frame during the arc short-circuit have been statically and dynamically simulated. All the results are summarized in the conclusion. Conclusion also contains the final evaluation of the functionality of both switchgear cabinets.

Development of the double-bass bow and selection of material
Prokop, Jan ; Hudec, Jiří (advisor) ; Žalud, Radomír (referee) ; Bernášek, Václav (referee)
This very bachelor thesis treats the problematic of history development and usage of bows from their origins up until the modern bows of today. It should be common for those who play string instruments to acknowledge this basic case of bows. That was the main reason for me to complete this work. The main problem while studying this theme was the vital shortage of expert literature on such problem. I was forced to seek information elsewhere using personal research consulting with experts and bringing of mine own experiences.

Informing and Communication with the General Public in the Course of Preparation and Dealing with Extraordinary Events.
PROKOP, Jan
This bachelor thesis seeks to investigate, by means of a questionnaire survey, the level of information of the general public about an extraordinary event, both in the stage of its prevention and in the stage of dealing with the event. At present, information is the alpha and omega in the society as the necessity to have correct and necessary information available increases quickly, also in the field of protection of the population, while the receiving of information, its correct evaluation and timely communication may affect lives and health of the population, the property, as well as the environment. In its introductory part the thesis, using available sources, deals with information and communication in general. This includes generation, spreading and utilization of information. It also covers the issues of extraordinary events, preventive educational activities, communication chains to spread information among the public and workplaces responsible for dealing with extraordinary events, as well as methods used to inform the general public in the course of extraordinary events. The other part of the thesis analyzes results obtained from the questionnaire survey and compares chosen results with the information obtained from informal interviews with professional workers. The results may be utilized by the Fire Rescue Service of the South Bohemian region to prepare specialized trainings for mayors of municipalities or for education of the general public. Conclusions of the thesis contain proposed methods to inform the general public, both during the preparatory stage of an extraordinary event and while dealing with it. It is very important for the general public to have the information necessary for proper conduct in case of an extraordinary event because only a well-instructed and informed person is able to protect him/herself and help the other people.

Hornychová, Martina ; Procházková, Markéta (advisor) ; Prokop, Jan (referee)
The aim of this bachelor thesis is to verify the advisability of setting up and operating a small bookshop in the town of Rokycany. The theoretical part deals with commerce, its functions and marketing in the area of retail procedure. The practical part, first of all, deals with the future of print version of books. Then the possible customer demand for a new bookshop is identified in Rokycany and its surroundings through the form of written questionnaire. Following the interpretation of answers given in the questionnaire, comes the proposal on how to put to use the information for the managing of the marketing mix of the possible bookshop. Next comes the analysis of competition, suppliers and verification of the price level of different books.

Travel ticket sales optimization at Prague Main Railway Station
Kuběnová, Eva ; Zelený, Lubomír (advisor) ; Prokop, Jan (referee)
This Master's Thesis concerns the travel ticket sales at Prague Main Railway Station. Based on a detailed analysis of provided data, its aim is to put forward suggestions on how to optimize travel ticket sales. Through evaluating the volume of travel tickets sold within the given time period and the number of open cash-desks, along with a cost analysis of sales channels, this thesis reaches its final conclusions. Microsoft Excel was the main analysis tool for compiling graphs. A sound knowledge of the current legislation which is stated in the theoretical part is necessary to help draw the right conclusions. This Master's Thesis, then, chiefly proposes informed suggestions on current sale process optimization in the ČD Center of Prague Main Railway Station.
