Similarity Searching in Network Data
Hud, Jakub ; Matoušek, Denis (referee) ; Wrona, Jan (advisor)
This bachelor thesis is interested in analyzing IP flow records. IP flow record contains IP flow metadata of specific network communication such as IP addresses, port numbers, network protocol numbers and other. Main goal is to design and implement method for determination of similarity of NetFlow records. At the beginning of this thesis is description of how to analyze great amount of data. Next there are shown network monitoring technicies and NetFlow. Other parts of this thesis are dedicated to design and implementation of data analysis using DBSCAN and agglomerative hierarchical clustering algorithms. Implementation of data analysis application is also part of this thesis. As a result, the application can be used to network scan detection using NetFlow data although the results are not very clear and contain a lot of legitimate communication.

Data analysis from moving vehicle
Kvapil, Josef ; Šedivá, Soňa (referee) ; Havlíková, Marie (advisor)
The thesis deals with data analysis obtained from the traffic simulator. The data are from trajectory of vehicle movement. The analysis are suggested to driving trajectory which are obtained from the characteristic parameters for the subsequent detection of the critical vehicle position. Analysis and evaluation of the detection critical vehicle position are solved in the Matlab program scripts.

Computational Model of Control and Behaviour of Self-Driven Vehicle
Kužela, Michal ; Bidlo, Michal (referee) ; Strnadel, Josef (advisor)
This thesis explains basic principles of autonomous vehicles. Based on these principles, it describes proposed simulation model of autonomous vehicle with its behavior in different outer conditions. The model is composed from sensors and vehicle itself. Sensors use an algorithm based on line intersection to detect collisions. Vehicle model is mostly described by physical formulas and custom decision algorithms. Its surrounding objects have parameters that are randomly selected for each simulation run. This thesis also explains implementation of the simulation model with its own simulation framework and an analysis tool for collected data. All of these features are implemented in JavaScript with use of Node.js and an Electron framework.

Data Mining Case Study in Python
Stoika, Anastasiia ; Burgetová, Ivana (referee) ; Zendulka, Jaroslav (advisor)
This thesis focuses on basic concepts and techniques of the process known as knowledge discovery from data. The goal is to demonstrate available resources in Python, which enable to perform the steps of this process. The thesis addresses several methods and techniques focused on detection of unusual observations, based on clustering and classification. It discusses data mining task for data with the limited amount of inspection resources. This inspection activity should be used to detect unusual transactions of sales of some company that may indicate fraud attempts by some of its salespeople.

Web application for Cybersecurity Job Ads Analysis
Turek, Adam ; Sikora, Marek (referee) ; Ricci, Sara (advisor)
Cílem bakalářské práce je vytvoření interaktivní celosvětové mapy zobrazující databázi pracovních inzerátů ve webové aplikaci a provedení filtrování podle různých parametrů, kde je následně provedena analýza strojového učení. Také mapa zobrazuje počet inzerátů na pracovní pozice podle příslušných států. Webová aplikace je vytvořena pomoci JavaScriptové knihovny ReactJS spojené s LeafletJS, které zajišťují hlavní funkcionalitu. Část se strojovým učením a změna skriptů je realizována pomocí programovacího jazyku Python. Práce popisuje teoretickou část a implementaci jednotlivých funkcí mapy a dále se zabývá popisem a úspěsnou úpravou skriptů pro účely provedení strojového učení.

Analysis of cryptographic operations on various processor architectures
Kubík, Hynek ; Gerlich, Tomáš (referee) ; Lieskovan, Tomáš (advisor)
Bachelor’s thesis analyzes cryptographic operations and algorithms on different server processor architectures. The thesis in its theoretical part deals with the analysis of individual cryptographic algorithms, processor architecture, computing cluster and HPC. An application is made for the analysis, which, depending on the input parameters, selected architectures and configuration selected by the user, performs the measurement of the performance of individual operations.The results from performance measurements and various cryptographic operations and architectures and with various input application parameters are subsequently years in the form of graphs.

Analysis of Data to Solve Problems with Humidity in Buildings
Nečasová, Klára ; Korček, Pavol (referee) ; Kořenek, Jan (advisor)
The aim of this work was to solve problems with excessive humidity in buildings using data analysis. The theoretical part of the work deals with impacts of excessive humidity on the health of building occupants and also the condition of the building structure. Data mining methods including classification, prediction, and clustering are described together with model evaluation and selection. The practical part focuses on hardware platform description and measurement scenarios. Key parameters affecting indoor relative humidity are indoor and outdoor temperature and outdoor relative humidity. The long-term measurement of the mentioned parameters was performed using the set of sensors and BeeeOn system. Measured data was used to design a system for event detection related to a humidity change. The approach to air change regulation in the room was based on natural ventilation.
