Use of a safety PLC for gas burners
Petr, Vojtěch ; Žlebek, Roman (referee) ; Polsterová, Helena (advisor)
The topic of this diploma thesis is the safety of a gas burner control. The aim is to fully automate the system by using a gas burner safety control system (Fail-Safe PLC) so as to reduce to minimum the risks. Because great emphasis is placed on safety, so Czech standards and what is connected with safety control systems are discussed. This project is implemented in cooperation with industrial automation company ElektroMAR a. s.

Temperature control of a multifunction hall
Petr, Vojtěch ; Šír, Michal (referee) ; Zezulka, František (advisor)
The topic of this bachelor thesis was to propose and program a control system for heating multipurpose halls. The system includes temperature sensors, circulation pumps, actuators, boiler for solid fuels, biogas plant and an electric boiler. Everything is controlled with a PLC CyBro-2, which communicates via ModBus protocol with a computer, where a graphical interface is programmed in Relaince 4. In the graphical interface customer can set the temperature value, choose a heating mode and export data of the heat consumption.

A Contribution to the Diplomacy of the United States of America and selected European Powers during the Wars of Independence (1776-1783)
Petr, Vojtěch ; Soukup, Jaromír (advisor) ; Tesař, Jakub (referee)
This bachelor thesis deals with diplomatic relations between United states of America and European powers in the time period of war of Independence (1776-1783). In 1776 the continental congress declares independence on Great Britain. United states need support, therefore they turn to the most likely option, France. That is when the first negotiations of the United States of America begin. Negotiations go well and in time France joins United states in war against Britain. At this moment the focus of Brittish shifts to European shores and France. Situation gets worse for Britain when Spain decides to join the war against them. Spain's main focus is in Europe, Gibraltar. After succesful siege of Yorktown, Britain surrenders the war. Peace negotiations start and delegates from United States are forced to go behind their allies backs and negotiate with England. Thanks to Shelburne, Britain succeeds in gaining as much as possible, and settles on 3rd of November 1776 by signing the Paris treaty. Goal of this paper is to analyze and evaluate brittish position after the peace settlement and try to find the motives for Spanish behaviour and their actual role and importance in the war.
