Automatická vizuální podpora pro Q-řazení
Kán, Dávid ; Hradiš, Michal (referee) ; Vaško, Marek (advisor)
This bachelor thesis deals with the integration of Q-sorting and computer vision methods for object detection. The goal of the work is to create a program that, with the help of~visual support, will facilitate the process and at the same time prevent errors in Q-sorting. Furthermore, the work deals with the creation of~a suitable data set for training the model and for experiments, which takes into account the way the cards are laid out and the~environment. The implemented program takes the form of a console application and is written using the Python programming language. The program uses YOLOv8 to detect objects and uses Pero OCR to retrieve text from cards. Using the created test set, experiments were performed on the trained model and the program was tested.

Data encryption on USB flash drive
Bráblík, Petr ; Benedikt, Jan (referee) ; Komosný, Dan (advisor)
The bachelor thesis deals with the design and implementation of a security program for encryption and automatic decryption of data on a USB memory stick. The system is designed to facilitate the use of the operating system on a USB memory stick for seniors in the age group of 90 years and above. The goal is to load a live version of the operating system that can be directly run from the USB memory stick. The implementation of a group of scripts will ensure automatic decryption of data according to the MAC address of the computer in which the USB memory stick is located. Furthermore, the work includes a graphical application for modifying the allowed MAC addresses for automatic decryption. The application allows to add enabled MAC addresses, view the history of computers in which the USB memory drive was located, and back up user data to another drive running the legacy operating system. The results of the work are published on GitHub.

Development of an algorithm for optimizing clock balanced cells in a digital standard cell library
Kříž, Lukáš ; Frýza, Tomáš (referee) ; Král, Vojtěch (advisor)
The bachelor thesis focuses on the analysis and optimization of clock-balanced cells in a digital standard library. The bachelor thesis was to explore the impact of cells in CMOS technology and assess their influence on the stability of the clock signal. Emphasis was placed on the effects of unbalanced clock cells in the path of the clock signal path, and the consequences that may arise if these cells are used. As part of the bachelor thesis, cells of logical operators such as buffer, inverter, AND, and OR were simulated. It is demonstrated how these cells are implemented in CMOS technology using PMOS and NMOS transistors, and the process of cell balancing is described. All simulations were conducted in the ngspice environment. Subsequently, the whole process was automated by developing an algorithm in Python.

Determining Stress Level from Heart Rate Monitoring
Hodulík, Hynek ; Strnadel, Josef (referee) ; Bidlo, Michal (advisor)
This thesis outlines the development of a prototype wearable embedded device intended for stress detection via physiological measurements utilizing an EKG sensor. Communication for the device is facilitated through Bluetooth LE. Accompanying the device is an algorithm designed to estimate stress levels locally based on collected heart rate variability data. Following a comparison of various methods, a multilayer perceptron was selected for stress detection. The proposed solution demonstrates an 85% accuracy rate in stress detection on WESAD dataset.

Rezervační systém sportoviště
Remeň, Juraj ; Křena, Bohuslav (referee) ; Smrčka, Aleš (advisor)
The aim of the bachelor thesis is the digitalization of the sports ground booking agenda, primarily based on the requirements of TJ Ochoz u Brna, but the system is also applicable to other small or medium-sized sports clubs. The system is intended to make the timetable of sports grounds in the municipality more transparent, to facilitate the creation of bookings for the sports grounds in question for the residents and to relieve the responsible persons from maintaining and using different systems for managing bookings, such as various Google or Excel spreadsheets or writing them down on plain paper.

Software extension of the education model
Koktavý, Ondřej ; Adámek, Roman (referee) ; Formánek, Martin (advisor)
This bachelor's thesis deals with the possibilities of communication with converters from the company FTDI using a program in Python. It focuses on MPSSE and communication using the SPI protocol. The thesis focuses exclusively on the communication with FT2232H converter, which is located in a single-motor educational model. The aim of the thesis is also to establish communication with educational model using one of the pre-prepared libraries. Subsequently, a function library will be created for this communication solution for users, including instructions for use. Within the framework of using this function library, the user will be able to use a total of three sample tasks. Measurement of the properties of this communication between the computer and the educational model will also be carried out.

Data Concentrator of 3D Printer's Sensors and Devices
Vaculík, Samuel ; Rusnák, František (referee) ; Arm, Jakub (advisor)
The bachelor thesis consists of designing and implementing a system for collecting data related to 3D printing. The aim is to define the variables suitable for measurement, select sensors for the measurements and implement them on the printer. The next point is the design and implementation of data acquisition from the printing firmware Klipper for collecting print data. Then the task is to implement the software for processing data from the individual measurement sources, including data flow analysis in the system.
