Electronic stability systems
Musil, Jan ; Ambróz, Richard (referee) ; Zháňal, Lubor (advisor)
In this Bachelor’s thesis there are basic electronic stability systems described. These systems are mostly used as a precaution in safety of the traffic, but also to ensure comfort of the crew. The main part of the thesis is focused on systems ABS, ASR and ESP. The other parts aim to describe additional systems, which are still in development. In the end there is also view of various individual car companies and possible steps in the future.

Dynamic verticalization
Ladický, Milan ; Čmiel, Vratislav (referee) ; Janoušek, Oto (advisor)
This bachelor thesis describes the design and construction of a tilt sensor of a dynamic verticalizer. The work contains a description of the verticalizer, sensing components and programmable boards, which are used to communicate with the computer and peripherals. The principle of connection between the verticalizer and the test application, the principle of sensing the patient's movements and the principle of EMG measurement are explained here.

Supervision and Control System for a Hotel Implemented by IoT Means
Hockicko, Matej ; Smrčka, Aleš (referee) ; Janoušek, Vladimír (advisor)
This work solves the design and prototype implementation of supervision and control system for a hotel implemented by IoT means. The solution is based on ESP microcontrollers, which control the connected sensors and actuators. ESP devices are futher grouped and connected to central point within range. Using this point, MQTT communication is futher transmitted to the cloud. The cloud runs the IoT Core service, which allows to control and store the status of devices. There is also a Node-RED developmnet tool, in which a graphical interface was created for this system. The result of this work allows remote monitoring and control of the hotel using sensors and actuators connected to this network.

Comfort and Safety Systems - Diagnostic Methods
Slíž, Martin ; Lapčík, Josef (referee) ; Hájek, Vítězslav (advisor)
This work deals with the division and description of the safety featutes of vehicles. Gradual entry into the safety of the crew of the car, from simple to very complex safety systems. The first part of this work deals with the basic division of safety features to active and passive systems. Here summarizes the most frequently used systems, their advantages and disadvantages. In the second part is described in detail system ABS (Anti-lock system), principle of operation, construction and other features of the system. The third part deals with the diagnosis of failures of security systems. It also included the creation of disorders, their symptoms and solutions. The last part of the two concrete examples of the use of diagnostic measurement system for ABS.

Design of Intelligent Network Module for 2D Radiation Data Acquisition
Lelek, Martin ; Polášková, Lenka (referee) ; Wilfert, Otakar (advisor)
This thesis describes about theoretical design and practical realization of self-contained module for intensity and absorbed dose measuring of X-Radiation from High Voltage X-RAY industrial sources. In the first part, thesis is focused on ways and solutions of radiation protection and principles of measuring absorbed dose and intensity of radiation and possibilities of sending measured data through sensor networks. In the second part, the complete schematic of measuring module is solved, critical blocks are tested and design of PCB is done. Detection circuit, blocks for optical and acoustic signaling, power management and control of the entire device are designed. Detection circuit uses a GM Tube. Next, main box of whole device is designed and made by 3D printing technology. The next step is putting hardware into operation and writing test firmware included verification of wireless communication through WiFi.

Distributed Control System with Dynamically Evolvable Nodes
Křek, Radim ; Kočí, Radek (referee) ; Janoušek, Vladimír (advisor)
This thesis describes creation of dynamically evolvable node, which will cooperate with other nodes. Group of these nodes will then create a distributed control system. The MQTT protocol is used for communications purposes between individual nodes. As hardware platform is used ESP32 and ESP8266. Whole operating system is written in MicroPython and supports a live uploading of user applications written in the same language. Later in thesis is decribed creation of monitoring node on Raspberry Pi, which control network. Complete system can be then used to control a intelligent house.

Risk Analysis of Self-Driven Vehicles
Weigel, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The goal of this thesis was to design and implement system for risk analysis in self-driving cars. This thesis focused on design and implementation of system for risk analysis in models. One of the requirements for the system was to be flexible and robust. Design of the risk analysis was presented at theoretical level and then implemented in models of ABS and ESP systems in UPPAAL environment. The system was then tested via multiple experiments. The experiments were beneficial and the system for risk analysis correctly evaluated failure scenarios with adequate response to the rising level of risk. Experiment outputs were then presented at graphs with comment to each failure scenario.
