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.

Web Visualization of Smart Devices Data in IoT
John, Petr ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
Due to the constant growth in the count of smart devices the need to store, aggregate and process the data effectively rises. The gathered data needs to be displayed effectively to the user, who will be able to react to the current state of the monitored device. This master's thesis deals with storing the data and displaying them using dashboards. The goal of this thesis was the creation of a library composed of components intended for data visualization and a simple API application, that can store and query the data effectively. The library is introduced in a simple application that uses the API application. Some parts of this solution are currently used in the company Logimic, where the costs of the database system reduced to 15 % of the average cost of the previous database system in the last 2 months. The rest of the solution is currently being integrated into the existing systems of the company.

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.

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.

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.

Interactive Guide for Zoological Gardens
Macháček, Martin ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
Even though a large number of zoological gardens fall under CSZOO union, there has been no unified way of presenting and managing this information. This project solves this problem by creating a unifying information system for any zoological garden, together with a modern mobile application, which serves as a pocket guide and a clear source of information from this system. In addition to functionalities such as events calendar, species, exhibitions or announcements, an interactive map is a very important part. Implemented system together with public stateless API is based on the Lumen framework. Mobile application is cross-platform and is based on Cordova technology. In order to establish certain form of frontend architecture, both the information system web interface and mobile application use framework Vue.js. Interactive maps are implemented through library called Leaflet in combination with Mapbox technologies. The created solutions exist as basic building blocks for future expansions and development.

Interactive Comparison of Train Connections
Uhlíř, Jan ; Holkovič, Martin (referee) ; Hynek, Jiří (advisor)
This bachelor's thesis is concerned by question of interactive comparison of train connections with graphic timetable. The first step was to analyze existing applications. Subsequently, an analysis of the available technologies for creating custom diagrams and database systems was performed. The product of this thesis is a web application which purpose is a graphic representation of traffic on the track in the form of an interactive graphic element. The displayed data can be filtered according to user's configuration.

System for Quality Control Management of Devices
Černý, Lukáš ; Hrivňák, Ján (referee) ; Hynek, Jiří (advisor)
This diploma thesis describes both the theoretical and practical part of the process of design and implementation of interactive computer software for the~management of~the~quality control of the~devices, assigned by SIGMA GROUP a.s., more precisely its Energo division, which is engaged in the maintenance and repair of pumping equipment. The theoretical part explains the concept of user experience, its acquisition methods, specification of~requirements and interface design methods. The next part is focused on the description of the~formats used by common text editors. Within the theoretical part is described the design of the interactive application itself. In the practical part there is a description of the main parts of the system and the conclusions from the system testing.

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.
