Integration, Visualization, and Mining from Data of World Countries
Dušek, Vladimír ; Rychlý, Marek (referee) ; Bartík, Vladimír (advisor)
This thesis explores the utilization of open data about countries around the world, particularly data in the areas of progress and quality of life. The goal was to design and implement a web application to present this data and further use the data for data mining. The integration and processing of data from open data sources were accomplished using the Apache Airflow platform. The Python framework FastAPI was used to create the API and the JavaScript library ReactJS was used to implement the web application. In the application, the indicators are categorized. Each of them can be displayed for different groups of countries, for different time periods, and in several visualizations. From the domain of data mining, clustering of countries based on a group of indicators and prediction of future development of selected indicators using regression analysis was performed. The final application is available at jakjsmenatom.cz.

Brain Signals Visualization
Ševčík, Ivan ; Drahanský, Martin (referee) ; Košík, Michal (advisor)
EEG je neinvazivní metoda pro měření mozkové aktivity, která poskytuje důležitý náhled do činnosti lidského mozku. Tato práce prezentuje aplikaci, která slouží jako vizuálni nástroj pro analýzu EEG dat. Koncept aplikace je založen na jiných existujících řešeních, které byly v rámci práce analyzovány. Aplikace kombinuje prohlížeč signálů ve formě vícenásobného čárového grafu s 2D a 3D vizualizacemi užitečnými pro rozpoznání specifické mozkové aktivity. Součásti aplikace je i sada metod pro zpracování signálu. Závěr práce je věnován shrnutí dosažených výsledků a plánů pro další vývoj aplikace.

Mathematical methods of morphology modelling of coniferous trees
Janoutová, Růžena ; Štarha, Pavel (referee) ; Martišek, Dalibor (advisor)
The thesis was focused on creation of a coniferous tree by nondestructive method allowing description of structure of adult spruce trees. After processing provided data we created a model of L-system which creates a tree branch. Thereafter, a Python script generated parameters which were required for the creation of the model of the tree in graphical software Blender. Model of coniferous tree was sucesfully generated. Its memory requirements are high but for our purposes this is not an essential problem.

Attribute Analysis of Data Presentation Using Information Dashboards
Loginova, Natalya ; Rudnitckaia, Julia (referee) ; Hruška, Tomáš (advisor)
Tato práce je věnována studiu některých aspektů použitelnosti vizualizace dat v informačních dashboardech. Cílem této práce je navrhnout model popisující vybrané druhy dat, které jsou nejčastěji používané v informačních dashboardech, a jejich možné grafické reprezentace, a poté implementovat nástroj na automatické generování vizualizací dat podle navrženého modelu. Nástroj mohou využít výzkumníci zabývající se zkoumáním různých aspektů grafické reprezentace dat k provedení uživatelských testů. Ukázkový průzkum uživatelů byl rovněž proveden v rámci tohoto projektu.

Set of Computer Exercises for Signals and Systems
Pálka, Petr ; Žmolíková, Kateřina (referee) ; Černocký, Jan (advisor)
The goal of this bachelor thesis is to transform the current format of materials for computer exercises from the Signals and Systems course into Jupyter environment. Current materials are divided by topics into individual PDF files that contain relevant theory and MATLAB code examples. These PDF materials cover basics of digital signal processing on computer. Produced Jupyter notebooks contain theory from original materials in Markdown + LaTeX, and MATLAB code examples are replaced by Python examples. In addition to current materials, they display output of the Python code which may include graphs, playable audio, text, image or some interactive combination of listed.

Practiceville
Res, Martin ; Pevný, Lukáš (referee) ; Macháček, Mikuláš (advisor)
The subject of the thesis is designing and implementing web application, which visualizes the impacts of alternative land use in a model village and its surroundings, pointing out possible advantages, disadvantages and risks of different land uses. The user is able to place buildings on the map and choose between different approaches to agriculture, forestry, water managment etc. The application visualizes the impact of users decisions in response.
