Meško, Tomáš ; Věchet, Stanislav (referee) ; Hadaš, Zdeněk (advisor)
This thesis focuses on the development of an interface designed to analyse and visualize the data collected from wireless microcontroller-based axes in a LoRa network. The type of interface chosen was a web page. The web page provides a visual display of the measured sections and plots the characteristic data in graphs. MySQL database structure was chosen as the storage method for the collected data.
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.

Design of Automation of Reporting Processes Using Business Intelligence
Schwarz, Ivo ; Klusák, Aleš (referee) ; Kříž, Jiří (advisor)
The bachelor thesis focuses on the design and implementation of automation of reporting processes at TEDOM Energie using Business Intelligence (BI) tools. The aim is to increase the efficiency of data processing and the speed of decision-making processes through modern BI technologies. The thesis analyzes the current state of the reporting system, identifies key issues, and proposes solutions to overcome them. It includes theoretical foundations such as the basic principles and components of BI, and a practical part, which deals with the selection and implementation of suitable BI tools and technologies. The result of the thesis is a design that was implemented and subsequently evaluated in terms of data processing efficiency and accuracy. The work demonstrates how BI tools, especially Microsoft Power BI, can transform processes in an organization and contribute to a better understanding and utilization of corporate data for strategic decision-making.
Support Tools for Verifying Human Ability to Detect Deepfakes
Potančok, Patrik ; Malinka, Kamil (referee) ; Firc, Anton (advisor)
Cieľom tejto práce je vytvoriť webovú aplikáciu s použitím PHP a MySQL, ktorá bude testovať schopnosť ľudí rozpoznať deepfake nahrávky a pritom zbierať ich údaje ako dátum narodenia, rodný jazyk, znalosti ďalších jazykov, koľkokrát a ako dlho počúvali nahrávku a počet správnych odpovedí. Aplikácia zahŕňa správu nahrávok a používateľov, a možnosť exportu údajov používateľov vo formáte CSV. Aplikácia bola implementovaná s použitím Laravel, Vue.js a MySQL.
Rationalization of production to improve roughness of a selected surface of rectilinear hydraulic motors
Urban, Jan ; Píška, Miroslav (referee) ; Sliwková, Petra (advisor)
In this paper, the influence of cutting parameters, machining strategies and material properties on the resulting surface roughness of a selected surface of a groove for a seal on the cover of a straight-line hydraulic motor are investigated. Based on the analysis of the results of the initial experiments of the existing production, specific measures are proposed to rationalize the manufacturing process. The effectiveness of the proposed measures is verified by further experiments carried out on real workpieces under industrial production conditions under the same manufacturing conditions. Subsequently, the results of the methods are compared with each other. The inclusion of a time delay between radial and axial feed during the finishing operation of the grooving had a very positive effect on the surface quality. The surface roughness values not only came within the prescribed tolerance but well below it. The economic evaluation shows that the rationalised production process does not have a noticeable effect on the overall cost of production and hence the results of this thesis are recommended for implementation in practice.
Password Leaks Automated Processing
Dvořák, Jakub ; Veselý, Vladimír (referee) ; Pluskal, Jan (advisor)
The aim of this thesis is to find databases of leaked data and to create an application capable of processing the data, storing it in a suitable database and enabling searching of the data on the basis of significant data. Among other things, the work deals with database research and measurement of uploading and data retrieval speeds, in order to select a suitable database used in the final solution. The resulting application is able to detect the encoding of the input file, the data format and stored items. Using the web interface, it also allows data to be searched based on filtering conditions from a database that has 5 157 229 040 records of leaked data at the time of theses submission. The results of this thesis provide a tool for processing and analysing databases of leaked passwords.
Comparing of Clustering Algorithms
Jakšík, Aleš ; Rozman, Jaroslav (referee) ; Zbořil, František (advisor)
This bachelor thesis deals with the comparison of K-means, K-medoids and Fuzzy C-means algorithms. In the first part, it discusses the types of distance measurements, clustering evaluation options and categorization of clustering methods. In the second part, it presents a web application for comparing the selected methods and in the third part it discusses the comparison and evaluation of the results and statistics from running the clustering algorithms in the demonstration application.
Mapping and analyzing signal coverage in 4G/5G mobile networks
Baránek, Michal ; Jeřábek, Jan (referee) ; Polák, Ladislav (advisor)
Tato práce se zabývá s pokročilým měřením kapacity a spolehlivosti v mobilních sítích, zejména s rozšířeným přijetím technologií 4G a 5G. Vzhledem k tomu, že se tyto sítě stávají stále více nedílnou součástí každodenního života, existuje potřeba efektivních řešení pro hodnocení a optimalizaci jejich výkonu. Primárním cílem této práce je vyvinout cenově dostupná softwarová a hardwarová řešení schopná extrahovat základní klíčové ukazatele výkonu (KPI) z mobilních sítí 4G/5G. Navrhovaný systém si klade za cíl poskytnout uživatelům přístupný nástroj pro hodnocení výkonu sítě, pokrytí signálem v konkrétních oblastech a prediktivní modely pro budoucí kapacitu sítě. Tyto funkce jsou prezentovány prostřednictvím uživatelsky přívětivého grafického rozhraní (tzv. GUI), které umožňuje přímočará a cenově výhodná měření ve venkovním i vnitřním prostředí.
Anomaly and threat detection in audit logs using machine learning
Ludes, Adam ; Ježek, Štěpán (referee) ; Tomašov, Adrián (advisor)
Tato práce představuje softwarové architektury založené na cloudu, techniky detekce anomálií, strojové učení a analýzu dat za účelem vytvoření modelu pro detekci anomálií v audit lozích z Red Hat OpenShift Container Platform. Jsou představeny statistické metody a analýza časových řad pro detekci anomálií, zatímco jsou implementovány a hodnoceny modely strojového učení a techniky předzpracování dat. Výsledky ukazují omezení tradičních modelů při zpracování anomálií v hluboce vnořených datech, zatímco model zpracovávající přirozený jazyk prokazuje robustní výkon. Tato práce poskytuje cenné poznatky a může být použita jako reference pro výzkum i praxi v oblasti softwarových architektur založených na cloudu, detekce anomálií, strojového učení a analýzy dat.
