Universal data storage for IoT applications
Kadlíček, Matej ; Myška, Vojtěch (referee) ; Šteffan, Pavel (advisor)
The master’s thesis is written about the topic of data warehouse and the technology associated with it. The aim of the theses was to select programming tools for creating a website. Next aim was to design the functionality, appearence and datastorage. Subsequent implementation of design was done after. Theses was divided into 5 chapters. The first one includes selections of programming tools for a creating a backend. Second chapter includes design of database storage. Third chapter includes design of functionality and user interface. Fourth chapter includes implementation of the application and the last one includes testing.

Control system for air monitoring
Chlumecký, Karel ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
The master’s thesis focuses on the development of household device which allows the user not only to measure quality and properties of air in individual rooms but also allows graphical display of measured values via wireless transmission. The work first deals with selection of a suitable microcontroller and then the wireless communications and used peripherals are briefly described. Furthemore, the work deals with the design of the device itself, its hardware and software equipment, as well as its construction. The financial costs are also analyzed in this work. Part of the work is the final testing of the completed equipment for measuring in two rooms of a residential house.

Equipment for long-term test of BLDC controller
Řihák, Roman ; Háze, Jiří (referee) ; Šteffan, Pavel (advisor)
This diploma thesis deals with the design and realization of equipment for long-term testing of the controller of brushless DC motors. In the theoretical part are mentioned principles and explanation of the function of various types of electric motors. The diploma thesis also deals with brushless motors, how they are controlled, types, constructed, etc. At the end of the first chapter there is a mention of thermoelectric phenomena. The second chapter describes the appropriate design of equipment for long-term testing from the block diagram to the construction itself. The third chapter deals with the implementation and function of the entire test system.

LoRa Gateway
Očenášek, Matěj ; Janůš, Tomáš (referee) ; Šteffan, Pavel (advisor)
This diploma thesis deals with the implementation of two LoRaWAN systems and the creation of instructions on how to put these systems into operation. Both systems consist of a end device, an access gateway, a network and application server, and a website to display the data obtained from the end device. The public network "The Things Network" and the local network ChirpStack are used to implement these two systems.

Design of low-voltage operational amplifier
Sysel, Jan ; Šteffan, Pavel (referee) ; Khateb, Fabian (advisor)
This work deals with the design of operational amplifier with extremely low supply voltage and low power consumption. In the theoretical part is presented theory dealing with the structure and design of operational amplifier. In the following part are desribed design methods suitable for realization of low-voltage circuits. In the next part were designed two operational amplifiers using low-voltage design methods. Properties of these operational amplifiers were then tested by simulations.

Electronic game Logic
Zemanová, Renata ; Šteffan, Pavel (referee) ; Háze, Jiří (advisor)
The goal of this bachelor thesis is to design and manufacture an Electronic game Logic. This electronic game should look like the board game and also respect the game’s rules. The electronic game is designed as one PCB that contains control electronics and play units. The functional PCB containing all electronics was manufactured. The game was programmed, and the final version was placed in a designed case. The Electronic game Logic also allows the player to set game mode options.

Battery management system for Formula Student
Macko, Maroš ; Bohrn, Marek (referee) ; Šteffan, Pavel (advisor)
This thesis is focused on battery management for Formula Student monopost. Part of the work is the design and implementation of this monitoring system. The system uses a distributed topology, is divided into the main subsystem and subordinate subsystems. The main subsystem and the selection of suitable components are described. Furthermore, subordinate subsystems are designed, and the fundamentals of battery voltage and temperature measurement are explained. Control firmware is implemented and it is able to communicate with the rest of the car. All systems were tested and they comply with the rules of the Formula Student competition.
