Performance Analysis of Go Programs
Nešpor, Andrej ; Malík, Viktor (referee) ; Pavela, Jiří (advisor)
The goal of this thesis is to extend the performance versioning system Perun by implementing a module for profiling programs written in the Go language. This module implemets the profiler by instrumenting function calls and returns using eBPF technology. The tool can collect function run times and their traces. We can then interpret the outputted profiles as a Sankey diagram. Additionally we implemented a new way of visualizing the measured data using the so-called Sankey graph, which will help with their interpretation. Using the developed profiler we conduct a few experiments to verify its functionality and demonstrate its use.

Gear design in Autodesk Inventor
Šanca, Kajetán ; Valena, Martin (referee) ; Okál, Michal (advisor)
This bachelor thesis deals with the visualisation of gears in Autodesk Inventor software. The thesis includes a theoretical introduction to the matter of gears, describes the principle of their function and basic division. It also focuses on the possibilities and practical use of the gear generator that the software has. Proper use of this tool will help the user to greatly speed up the design of gears. The result is a comprehensive tutorial in the form of presentations, which describes the visualisation of different gear types from design to animation, with the functional use of the gear generator. These presentations will be used as teaching materials for students in the 3CC course, which deals with advanced 3D modelling methods.

Dashboard for Smart Home Status Focused on Low Consumption Installations
Fišer, Tomáš ; Hynek, Jiří (referee) ; John, Petr (advisor)
In the rapidly evolving concept of IoT, or a network consisting of physical devices with electronic and software capabilities to interconnect and collaborate to perform autonomous actions without human intervention, dashboards are an important element for users, providing data visualizations and controls over data. This work deals with the creation of a dashboard that has as main goals low energy consumption compared to traditional solutions, simple control interface and clear data visualization. It tries to meet the parameter of low power consumption by using energy efficient computing hardware, ESP32 microcontroller and by using E-ink display panel which again has low power consumption. The resulting dashboard should be able to run on batteries for long periods of time without the need to replace or recharge the batteries.

Algorithms and Methods of Statistical Processing of Q Sorting
Burešová, Zuzana ; Beran, Vítězslav (referee) ; Herout, Adam (advisor)
The goal of this bachelor thesis was to learn about Q-methodology, create a Q-sort for test data extraction, convert test data into JSON format, experiment with data visualization and evaluation, and create a library for evaluating and visualization of the Q-sort data. The paper includes a report on the technologies used and a description of each tool implemented in the developed library. My main focus was on data visualization, where I experimented with different graphs and visualization libraries. With this library, the user can easily evaluate and visualize the data obtained from the Q-sort.

Web application for visualization and analysis of correlation rules deployed in cyberspace
Závišková, Hana ; Říha, Kamil (referee) ; Safonov, Yehor (advisor)
In a world of constantly evolving modern technologies, there is a growing need of developing cyber security strategies to protect digital infrastructures as the number of cyber attacks is rapidly increasing. The main goal of the bachelor thesis is to create a tool for visualizing correlation rules of SIEM systems. The tool is implemented as an extension to an existing web application and aims to allow a security expert or application user to explore user Sigma rules according to different criteria and based on different views. From a theoretical point of view, the bachelor’s thesis focuses on introducing the reader to the basics of cyber security in terms of the motivation for providing security, explaining the basic concepts necessary to understand the content of the thesis and analyzing the perspectives in which cyber attacks can be viewed. It also contains a description of selected cyber attacks, the selection of which is based on the statistics of cyber attacks on the Czech Republic for the first three quarters of the year 2023. This is followed by an explanation of the principles of detection and prevention of cyber incidents, technologies for ensuring protection in cyberspace, including the issue of log sources and platforms for detecting information about threats and the principles of cyber incident investigation. This is followed by an introduction to the legal regulation of cyber security, including a description of ENISA recommendations. The practical part of the bachelor thesis is further divided into four chapters. In the first part, an analysis of available web frameworks that can be used in application development and an analysis of the rule visualization methods used in two modern SIEM solutions were performed. The second phase focuses on the design of different views that can be used to provide a pleasant, intuitive and interactive environment for displaying user rules. The visualization designs include the components available in the D3.js library and working with the MITRE ATT&CK matrix. The second phase also includes the creation of a structure for the layout of the elements in the web application. The third phase is oriented towards approaching the actual implementation of the appropriate views that result from the analysis performed in the second phase. It also includes a description of the experimental environment in which the application was developed and how the data was obtained. The last phase focuses on testing the visual part of the application from the user’s perspective. The whole thesis finishes with a conclusion, which summarizes the results of the bachelor’s thesis, which have been achieved, and suggestions for improving the application in the future.

Simulation Environment for Objects in Low Earth Orbit
Pospíšil, Zbyněk ; Hanák, Jiří (referee) ; Novák, Jiří (advisor)
Tato práce se zabývá problematikou předpovědi polohy satelitu na Nízkém orbitu Země a vizualizací těchto dat v samostatném programu. Takových cílů je dosaženo použitím jak analytických, tak i numerických integračních metod, analyzujících orbitální parametry získané z veřejných databází ve formátu TLE. Účelem práce je srozumitelně přiblížit tuto problematiku veřejnosti a nadšencům. Celý průběh simulace je zachycen v grafickém prostředí a umožňuje uživateli ladit podrobný běh simulace.

Upgrading the Subsystem for Testing of the Safety Function of a Valve
Němec, Petr ; Fiedler, Petr (referee) ; Arm, Jakub (advisor)
The aim of this work is to develop a theoretical basis for the modernization of the subsystem for testing the valve function, the subsequent design and implementation of the visualization. The thesis briefly describes the steam turbine circulation and bypass technology. Thus, the technology of the system in which the safety function itself is located. Furthermore, the thesis deals with the functional safety analysis and describes the development of three analysis methods FTA, HAZOP and FMEA. The thesis also deals with the analysis and description of an existing application using a state diagram. From the subsequent analysis, the design of a new visualization is realized. The visualization is tested in the thesis using simulation which is performed on a real PLC and also using PLCSIM software.
