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.

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.

Mobile Application for Management of IoT Devices
Colníková, Ivana ; Tesařová, Alena (referee) ; Hynek, Jiří (advisor)
The main goal of this thesis is the creation of Angular modules for the system of Logimic company. These modules represent the elements of the system's mobile user interface and aim to provide an improved user experience in terms of the system's interface and usability. The system provides an overview of sensor states with the ability to easily send service requests. In this thesis I have analyzed the system's current state and proposed suggestions for improvements. The implementation of these improvements were done by using Angular framework and PrimeNG library. The thesis also contains the testing and integration of these modules into the current system of Logimic company.

Web Interface for RDF Storage Browsing
Tomov, Patrik ; Hynek, Jiří (referee) ; Burget, Radek (advisor)
The aim of this thesis is to create a web interface for browsing the RDF storage, where the user will be able to manipulate its content. Within the storage, he will be able to create and delete repositories, add and delete repository content, view and interact with repository content, and also perform SPARQL queries within the repository. The client part of the application is written in Javascript using the Vue framework. The RDF4J server, which is deployed on the Apache Tomcat service, is used for the server part. Communication between the server and the client is secured using the RDF4J REST API. The resulting application allows to interactively and easily browse the content of the RDF storage.

System for Managing and Paying Invoices
Seipel, Richard ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
This work aims to simplify the process of paying invoices and also reduce the need to send them in paper form. The system includes the ability to enter invoices from companies, the interface for their display, and the use of the PSD2 directive for their payment. The core of the system is implemented in Python, using the Falcon framework to create the REST API. The necessary data is stored in a database created in PostgreSQL using SQLAlchemy. The client-side is created as a web application, using the usual tools HTML, CSS, Javascript, and the React framework. The submitter of this assignment is the Payment Institution Roger a.s., which has a license to use PSD2 payments.

Web Graphical Visualization of Hierachical Geographical Data
Malý, Vojtěch ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
This work aims to create a tool that can be used in creating web geographic visualizations with the use of hierarchical relationships between geographical objects. This is done for example by disintegration or clustering of various administrative units such as districts or regions based on different zoom levels of the map. This will provide the user with additional options for creating more effective geographic visualizations that can show the displayed phenomena from different angles. Tool will also provide a user interface for downloading the data representation of geographic objects using API and will allow aggregation of data according to individual levels of the hierarchy. This tool is an optional part of Geovisto, which provides tools for the visualization of generic data in web browsers on various thematic maps.

Complex On-Line Training Diary
Kamenský, Zdeněk ; Hynek, Jiří (referee) ; Bartík, Vladimír (advisor)
Design and implementation of online training diary for athletes is the main goal of this thesis. At the beginning, it was necessary to explain some of key words, related to the thesis topic. One of the most important things is data mining and its usability for sports data analysis. After that, existing solutions of sport applications were analyzed and also it was obligatory to analyze potential users requirements. Application design, implementation and testing were the next steps. Some of data mining methods were used for analysis of sports data intended for individual athletes and their coaches.
