Design of low-cost control unit for DC/BLDC motors
Pospíchal, Tomáš ; Najman, Jan (referee) ; Rajchl, Matej (advisor)
This thesis deals with design and construction of motor driver, firmware for STM32H7 a software UI in Python. Motor driver has four total half bridges, from two H-bridge Smart Gate Drivers. Motor driver is designed for 100W DC/BLDC motors. Communication over USB 2.0 HS, using CANOpen protocol with IEC 61800-7 device profile. Motor driver could be used for lectures and demonstrates USB 2.0 HS capabilities of STM microcontroller.

Web application for antenna analysis
Večeřa, Štěpán ; Kadlec, Petr (referee) ; Raida, Zbyněk (advisor)
Měla být vyvinuta webová aplikace pro zjednodušenou analýzu anténních polí. sestávající z drátových dipólů nebo náplasťových prvků. Původně se předpokládalo, že výpočetní jádro bude vyvinuto v prostředí MATLAB a webové rozhraní v jazyce Python. Studie proveditelnosti ukázala, že plné v jazyce Python je výhodné. Vyvinuté funkce Pythonu pro analýzu a syntézu antén jsou stručně popsány a jejich funkčnost je ověřena v prostředí MATLAB.

Intelligent Energy Measurements for Homeowners' Association Using 5G Networks
Horčička, Patrik ; Možný, Radek (referee) ; Mašek, Pavel (advisor)
Theoretical analysis of IoT communication technologies LPWAN. A more detailed analysis of 5G-IoT technologies in the licensed frequency band, such as NB-IoT and LTE Cat-M. List of supported application protocols for IoT devices (MQTT, CoAP, LwM2M, DLMS/COSEM) with more detailed information about DLMS/COSEM. Quectel UMTS \& LTE EVB kit with BG770A-GL module was used to create the first reference 5G-IoT device. Measuring of radio properties in two locations. Creation of TLS tunnel for communication between Virtual computer and RPI designed for DLMS/COSEM data.

Automatical plant growing
Stupka, Tomáš ; Dřínovský, Jiří (referee) ; Götthans, Jakub (advisor)
The aim of the thesis is to design and an automated hydroponic station, which will be intended for the cultivation of herbs and vegetables for the purpose of user. The station will be controlled by a Raspberry Pi minicomputer, to which a number of sensors will be connected, which will check pH, EC, ambient temperature and other quantities. Furthermore, an external sensor with an ATMEGA328P control processor will be designed to check the ambient lighting parameters. A web interface will be created for the station, which will allow the user to follow the development of individual measured quantities over time.

QR code detection using deep learning
Černohous, Matěj ; Kříž, Petr (referee) ; Přinosil, Jiří (advisor)
This bachelor thesis deals with the design of an algorithm for detecting and decoding QR codes in images using deep learning techniques. The work involved the construction of 2 datasets, a YOLOv7 neural network model for detecting QR codes in images, a YOLOv4-tiny neural network model for detecting position markers of QR codes, and a Python program utilizing these models to read QR codes in images. For evaluation, the algorithm was compared with other options for QR code reading.

Presentations Making Blender add-on
Telmanik, Ronald ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
Cieľom tejto práce je vytvoriť nástroj, ktorý umožní používateľom programu Blender vytvoriť prezentáciu vo forme snímkov. Tento proces je zvyčajne časovo náročný spôsobené najme komplexnosťou program Blender. Preto na uľahčenie tohto problém je vytvorené rozšírenie pre program Blender. Toto rozšírenie implementuje sadu nástrojov, ktoré uľahčia tvorbu a neskôr aj samotnú prezentáciu v reálnom čase. Finálny zdrojový kód rozšírenia je voľne dostupný na platforme GitHub.

Product quality control
Pitrun, Tomáš ; Janáková, Ilona (referee) ; Boštík, Ondřej (advisor)
The bachelor’s thesis deals with the industrial inspection of defects on injection molding based on computer recognition. Part of the work is a description of injection molding technology and defects that may occur with this technology. The detection application is implemented in Python on the Raspberry Pi platform. The OpenCV library is used to detect product defects. Part of the work is also the selection of suitable hardware resources, including the Raspberry Pi microcomputer, lighting camera module, lens, relay modules and supporting structure.

Design and implementation of VoIP protocols tester
Polášek, Jakub ; Číka, Petr (referee) ; Krajsa, Ondřej (advisor)
This paper deals with ways and means of testing SIP or IAX2 based equipment and protocols itselfs. I analyse terminology and methodology for benchmarking of proxy and registrar servers as it was described in documents RFC 7501 and RFC 7502 from organization IETF. In the practical part is described the tester realization programmed in PHP programming language witch will use described methodology. Aplication is available in web based interface.

System Log Analysis
Ščotka, Jan ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The goal of this master thesis is to make possible to perform system log analysis in more general way than well-known host-based instrusion detection systems (HIDS). The way how to achieve this goal is via proposed user-friendly regular expressions. This thesis deals with making regular expressions possible to use in the field of log analysis, and mainly by users unfamiliar with formal aspects of computer science.

A Tool for Post-Mortem Debugging
Kapičák, Peter ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The goal of this work is checking specific properties in trace which program should meet or which it shouldn't meet. Properties and their description are basis of this tool for post-mortem debbuging. Properties are transformed to deterministic finite automaton for checking in trace and their description is important for searching events in trace. Events are pass to automaton as input. Output of a tool is report if properties are meet or not. Solution provides check of properties regardless of log format and shows events that preceded violation of the properties.
