Virtual TableTop for playing the Dungeons and Dragons board game
Horák, Vladimír ; Polášek, Tomáš (referee) ; Čadík, Martin (advisor)
The goal of this work is to create an open-source 2D virtual tabletop for the board game Dungeons and Dragons and similar TTRPG games, which implement some bonus features, leading to better gaming experience. The main improvement is in extending the toolbox of other virtual tabletops by adding support of multiple layers, improved inventory support and automation of some time-consuming elements like area of effect spells. In addition the game will run directly on local devices, improving performance and removing limits of storage capacity and file size, which are common among cloud based virtual tabletops.

Creating a simulation model of the access network
Formánek, Juraj ; Slavíček, Karel (referee) ; Grenar, David (advisor)
Thesis deals with generating and monitoring traffic in the GNS 3 simulation tool. The properties of the GNS 3 simulator are defined, including its capabilities for simulating/emulating components. Emphasis is placed on using only open-source tools. After analyzing the capabilities of GNS 3, a suitable traffic generator is found, which is preceded by practical testing of multiple generators. After finding the generator, monitoring tools are practically tested, with Zabbix emerging as the best from the tests. It was linked with the visualization tool Grafana through Zabbix plugin. Part of the work consists of automation, managed by Zabbix along with bash/Python scripts. The thesis evaluates the use of GNS 3 and explores its capabilities, possibilities, and limitations in the area of traffic monitoring and generation. The result is the creation of an access network with one router and two containers that generate and send traffic through this router. Everything is monitored by Zabbix and useful results are displayed in Grafana.

MES for Industry 4.0 demonstrator
Martiník, Tomáš ; Arm, Jakub (referee) ; Kaczmarczyk, Václav (advisor)
This bachelor's thesis deals with manufacturing systems, their functionalities and their role in Industry 4.0. This thesis focuses on the design and implementation of the MES solution for the Industry 4.0 demonstrator. Research of available open-source systems is conducted and, based on the requirements for the system, one solution is selected, modified for the demonstrator's needs and integrated into its system.

Creation of E-commerce for an Entrepreneur
Prchal, Tomáš ; Kříž, Jiří (referee) ; Luhan, Jan (advisor)
This bachelor thesis deals with the introduction and comparison of different platforms for creating e-commerce for entrepreneurs. The aim of the thesis is to provide an overview of the advantages and disadvantages of each platform, as well as to compare their features and capabilities. The thesis will also include a practical part, in which specific platforms for creating a customized e-shop will be compared and the steps required to create an e-shop on the platform that best suits the requirements of the entrepreneur will be described. The work should result in a detailed guide for selecting a suitable e-shop solution, considering the current situation and the needs of the entrepreneur.

Open Data and Transport Modelling
Grishchuk, Dmitrii
Computer modelling has become one of the main methods of predicting the behaviour of traffic and passenger flows within small areas, cities, or entire regions. Sometimes the lack of data, either open or proprietary, or the lack of knowledge of where to find it and how to prepare it, is an obstacle to the development of a traffic model.
In this paper, the author has chosen to focus on finding and processing the freely available data on the population, infrastructure, facilities characteristics and placement for developing traffic models in any locality in the Czech Republic, regardless of size. The format of the processed data is chosen in such a way that it can be used for other analytical purposes.

Using free programs for topology optimization on selected problems in solid mechanics
Flídr, Ondřej ; Halabuk, Dávid (referee) ; Vosynek, Petr (advisor)
This bachelor thesis examines open-source software for topology optimization, analyzes their possibilities on selected problems of solid mechanics and verifies the results by the finite element method. The theoretical part describes the principles and methods by which the tasks of topology optimization can be solved. This is followed by search for open-source software using these methods. The calculation process in selected software is described in detail in solving sample tasks in the penultimate part. In the last chapter, the best open-source software are compared with each other and also with commercially distributed Ansys Workbench 19.2. The output is an evaluation of the usability of individual open-source software in industry. This thesis can also serve as a manual for using selected programs for inexperienced users.

Security Analysis of Home IoT Network
Čikel, Tomáš ; Jeřábek, Kamil (referee) ; Pluskal, Jan (advisor)
This work focuses on the issue of the security in home IoT network. Specifically, it focuses on the security issues of commercial IoT devices and their automation systems. In the work itself, it was firstly analyzed and identified specific threats specific for our network. To address these threats, the original automation systems and firmware on the devices were replaced by open-source implementations that were configured to address discovered threats. Although, there are still several security issues in a network with an open-source implementation, a large part of the security issues which were discovered has been eliminated. The results of this work allows to configure a home IoT network using an opens-source automation system and firmware and proves that such a network is more secure than the network where the original factory-supplied automation systems and firmware on devices are used.

Analysis of Wi-Fi traffic
Bakó, Zdeněk ; Pospíšil, Ondřej (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with the capture and analysis of wireless traffic of Wi-Fi networks. The aim of this work is to describe the possibilities of capturing and analyzing the operation of Wi-Fi networks. It describes the IEEE 802.11 standard, its features such as architecture and current standards. A selection of a suitable router is performed on which traffic capture and analysis is performed. Some open-source firmware for routers is compared and the most suitable one is selected. Tools for capturing and analyzing Wi-Fi network traffic are compared and described. The differences between the promiscuous and monitoring capture mode and their possibilities of use are described. Finally, there are described options for analyzing captured 802.11 frames.

Using Calculix computing environment to solve problems of solid mechanics
Lukáš, Jan ; Lošák, Petr (referee) ; Vosynek, Petr (advisor)
Submitted bachelor thesis is focused on a solution of solid mechanics problems in a computing environment of the Calculix program. In the opening of the thesis there are briefly described theoretical foundations of finite element method. Subsequently there are analyzed particular parts of the program environment of Calculix. The main part of the thesis deals with solutions of three selected problems of solid mechanics. There are three different types of analyzes: static structural, modal dynamic and explicit dynamic. In the first assignment there is discovered deformation and stress in a fixed compressed squared timber. The second assignment deals with modal properties of the fixed squared timber. The last assignment discovers effect of loading velocity on the deformation of fixed compressed squared timber. In the conclusion there are briefly evaluated advantages and disadvantages of the Calculix program and there are compared solutions of the Calculix program and commercial program.
