Generating Program Code from Ontology Definition
Svetlík, Tomáš ; Hynek, Jiří (referee) ; Burget, Radek (advisor)
This master thesis deals with the process of generating source code from ontology definition. It is advantageous to have ontologies in the source code representation, when developing ontological applications. This source code expresses ontology classes and properties. The main goal of this thesis is to develop an implementation of the tool that uses this process. The thesis describes the design, implementation and testing of this tool. The result is a fully functional source code generator. It is able to generate Java or Python source code. Functionality and reliability were evaluated according to testing with set of actually used ontologies.

Mobile Application for Tracking and Sharing Cyclists Location on Map
Schléger, Richard ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
This thesis deals with analysis, design and implementation of mobile application and application for smartwatches for tracking and sharing location of athletes, especially cyclists. Main goal of this application is to increase level of safety of athletes during the activity. This task is accomplished by location sharing and also by automatic fall detection and following notification. Final application is intended for mobile operating system Android and iOS a also for smartwatches with Wear OS. Theoretical part is dealing with analysis of actual trends in cycling, mobile applications and smartwatch applications development. Implementation part consists of design of application, implementation itself and testing.

Programming Abstraction of Geovisto Library
Chládek, Martin ; Rusňák, Vít (referee) ; Hynek, Jiří (advisor)
The purpose of this thesis is to create an extension of the Geovisto library, which aims to make the visualization and presentation of geographic data in modern web applications easier. This work analyzes possible integrations with popular web UI frameworks and design extensions that help integrate the tool within client projects. The goal is to develop an abstraction for the core and other modules of the Geovisto library, which enables declarative configuration of visualized map layers by users of the abstraction code. The implemented extension consists of a set of predefined configurable React components. Using the components makes it possible to initialize the map view and dynamically change the rendered content. The solution is exported as a separate library and was created using mainly the technologies React and TypeScript.

Web Interface of a Document Analysis Tool
Ševčík, Adam ; Hynek, Jiří (referee) ; Burget, Radek (advisor)
This thesis deals with the development of a web interface of a web document analysis tool. Goal of this interface is to replace old desktop application FitLayout. Own front-end is added to FitLayout back-end. This application is made by Javascript, HTML and visual part is done by CSS and framework Bootstrap. Web documents are in format RDF serialized in JSON-LD. Data are exchanged in the same format between client and server. Result of this thesis enables user to analyse documents in browser same way as in desktop application.

Web Editor for SPARQL
Paulovič, Daniel ; Hynek, Jiří (referee) ; Burget, Radek (advisor)
Target of this thesis is to create web editor for query language SPARQL as component in javascript framework Vue.js and web application using this component to query over SPARQL endpoints. To implement editor were used CodeMirror library and PrimeVue library for user interface. Final version of component is publicly available as npm package. Benefit of this thesis is easily importable editor with many functions to simplify writing queries.

Processing and Storing of IoT Data with Focus on LoRA Sensor Networks
Moravčík, Tomáš ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
This Bachelor's thesis deals with developing a web application designed to add LoRa devices to the LoRaWAN network. The application meets the requirements of progressive web applications, which allow the application to be portable and yet to behave like a native application. Devices are added to The Thing Stack cloud platform, which serves as the LoRaWAN network server. The application was developed in TypeScript in the Angular environment. This work aims to increase the efficiency and speed of registering devices to the network and reduce the difficulty of the process. Work was accomplished in cooperation with the company Logimic.

Processing and Storing IoT Data in Relational Databases with Application of Cloud Services
Hlava, Jakub ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
Smart cities and systems for their management are constantly producing great amount of data, which needs to be processed and stored. The goal of this Bachelor's thesis is to create a tool, which will make developers able to test influence of this amount of data on their system, especially on database server. Then they will be able to adjust their cloud infrastructure for assumed level of load before it's real-world deployment. The tool is developed using Python programming language as collection of components which makes scalable load testing possible from many places at the same time. Data about the course of test and about service of PostgreSQL database server is collected by the tool during testing. Course of the test can be controlled and monitored by user using integrated web interface, which also visualizes collected data in form of charts. The tool was created in cooperation with Logimic, s.r.o., tailored to their system for smart cities management.

Mobile Chat for Communication between the Athlete and the Coach
Zaukolec, Jakub ; Hynek, Jiří (referee) ; Tesařová, Alena (advisor)
The aim of this thesis is to design and implement a mobile application for Android, that serves to facilitate work of coaches to communicate with their athletes and clients. It is a mobile chat with which coaches are able to provide adequate feedback to their athletes during training. Beginners in area of exercising are able to better understand how to perform each exercise and how they can minimize mistakes during exercising. The application also provides them to store data about their trainings, so they have all the necessary informations in one place, where they can be found very easily.

Usability Improvement of Geovisto Library
Koscielniak, Tomáš ; Rusňák, Vít (referee) ; Hynek, Jiří (advisor)
This thesis aims to improve the user interface of Geovisto library, used for geospatial visualization. This is achieved by identifying issues using user testing and designing a solution for them. These solutions were implemented, and the second user testing tested their benefit. The result of the thesis is expanding the library with legends, units for numerical values, and tools for visualization of metadata, which all improve the user experience when using the library. Another result is a standalone web presentation of the library, its tools, and data miner.
