Measurement of basic electrical variables on drives of LV circuit breakers
Mazálek, Tomáš ; Valenta, Jiří (referee) ; Bušov, Bohuslav (advisor)
This thesis has been created for the purpose of comparing calculated values by oscilloscope and by Excel. There is also introduced the procedure calculating the maximum generated power by using macros in Excel. For this it was necessary to show a theory of electrical values of non-sinusoidal and aperiodic signal. There has been shown the methods of measuring of power consumption on motor operator for acquisition of relevant data. My thesis brings a wide overview, which is connected with motor operators. I am analyzing a principle of motor operator, methods of right measuring and I am describing a transfer of kinetic energy from driving motor to contacts of circuit breaker

Home automation, input and output modules
Ponechal, Mikuláš ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The bachelor´s thesis mediates theoretical analysis of home automation using IoT application. The aim of the thesis is to desing input and output modules to make controlling of electronic devices easier for user. The first chapter describes wireless technologies which are mostly used in IoT applications, principles of measuring current in order to determine energy consumption and ways how to dim lights. The second chapter includes design of wireless communication between the modules and a central control station and specific module designs. The third chapter deals with the construction and testing of hardware modules.

Experimental Stand for Determination of Turbocharger Lubricant Consumption
Kuhajdik, Matej ; Doman, Jozef (referee) ; Novotný, Pavel (advisor)
This work solves the problem of lubricant consumption in the turbocharger and air blow–by from the compressor part of the turbocharger into the bearing housing. The chosen problem is solved by the design of the test mechanism that will be used in the technical experiment. The experiment provides analysis options for the GT35 turbocharger rotor seal. Part of the work is a complete drawing documentation of the test equipment, installation procedure and instructions for operating the equipment.

Energy sources and consumption
Majer, Jan ; Kuba, Pavel (referee) ; Bobák, Petr (advisor)
The thesis describes basic methods of producing energy and presents the basic division and characterize sources of energy. It compares and describes the production of energy in the Czech Republic and the United States of America. The thesis explains, where and how is this energy consumed and presents energy production and consumption in the Czech republic and in the United States of Amerika and provides a comparison of the two countries. Indicates the percentage of consumption in various sectors in these countries and the distribution of energy consumed by resource used. The thesis is also focused on the comparison of household consumption in the Czech Republic and the United States of America. It specifies the average household consumption of Prague and New York and investigates the causes of the difference in average household consumption of both countries.

Control system for cantilever gates
Koždoň, Ondřej ; Arm, Jakub (referee) ; Bradáč, Zdeněk (advisor)
The goal of this bachelor's thesis is to design a battery powered control system for wireless controlling swing gate (may be used for cantilever sliding gates or garage doors). This system is designed as a small electronic system with necessary Inputs/Outputs (I/O) and an Input for charging a battery from solar cells. The result of this bachelor's thesis are two main PCBs with dimensions of 5×5cm for controlling the gate and remote controller with dimensions of 2,3×4,4cm. Main PCB allows adding more remotes, deleting all remotes and modes for the way of controlling the gate (opposite direction, open only, close only, open wing, close wing, stop the gate) and selecting Master/Slave gate. Communication works on frequency of 434MHz.
