Mobile Application for Management of Smart City Service Requests
Formánková, Klára ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
The aim of this thesis is to develop a mobile application for managing service requests in smart cities and it is done in collaboration with Logimic company. Service requests represent activities that need to be performed in a city, where managers are responsible for managing them and technicians are responsible for executing them. This thesis intends to analyze the current state of support for service request management on a smart city platform and to design and implement a solution for effective service request management in the form of a mobile application for both Android and iOS platforms. The result of the work is a multiplatform application developed using Ionic and Capacitor frameworks, which allows more efficient work with service requests by organizing them into a graph structure, merging duplicate requests and introducing some typical mobile elements. The resulting application is also integrated as a module of the smart city platform. An important contribution of this thesis is the verification that using frameworks Ionic and Capacitor, a web application can be easily transformed into a multiplatform one.

The aim of this semester project is to design and implement an information system for managing geographic objects created using the Geovisto programming library. As part of the project, the user should be able to save their created geoJSONs using tools, share them with other users, and import their own geoJSON files. The system was designed and implemented in JavaScript and utilizes the JavaScript frontend library React to create user interfaces. Additionally, the user database and their stored GeoJSONs were implemented using the object-relational database system PostgreSQL.
Web Visualization of Quality Control Data from Industrial Devices
Kozhevnikov, Dmitrii ; Hynek, Jiří (referee) ; John, Petr (advisor)
Currently, each specialist is faced with a large amount of data, and his goal is to work with them as efficiently as possible, but there are not often platforms that are able to provide an effective display of information for each user and have the possibility of individual customization. This bachelor thesis deals with data storage and display using dashboards. The aim of the work was to design and create a dashboard for organizations focused on quality control, which will allow not only to effectively display the necessary data, but also provide the user with the opportunity to customize the displayed information depending on his requirements and tasks. Some parts of this solution were deployed by Sanezoo. The result of the work done is an application for data visualization, which provides the user with data in tables in a convenient form, and also allows you to create and edit charts that will be displayed on a special dashboard. The application has been tested both with the help of automatic tests and by real users. In the future, new options will be added according to the test feedback and the application will be integrated into the Sanezoo application.
Street Light Control on Smart City Platform
Jůzl, Radek ; John, Petr (referee) ; Hynek, Jiří (advisor)
The goal of this bachelor's thesis was to design smart public lighting on the Smart City platform. The proposed solution is located in the ACADA system, where the light profile is generated. The generation of light profiles is based on the presence of people in the area. The user is allowed to set the parameters of the occurrence limits for individual percentages of luminosity.
Information System for e-Learing Courses Testing
Kříž, Vítězslav ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
A long-term trend in modern digital education is the shift from static content to interactive e-learning courses. The focus is often on the form of information delivery rather than the content. The testing part of development tends to be ineffective, as there is no easy way to obtain information about student behaviour. This paper addresses this problem by creating a testable web application, xTester, that allows tracking key metrics of developed e-learning courses communicating through xAPI. The solution includes an enhanced course template in Articulate Storyline and a browser add-on to facilitate linking of created courses to the xTester application. General issues and specific stages of development are described, from specification of user requirements, interface design and implementation, to testing. The frontend of the web application is based on the Vue framework, the backend consists of a simple stateless Rest API in Node.js with a SQLite database.
Optimization of KPI Processing
Šulc, Ondřej ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
This thesis deals with the optimization of data processing from IoT sensors of smart cities into the form of key performance indicators (abbr. KPI). KPIs are a mean of monitoring a large amount of data and expressing the status of performance factors affecting the prosperity of the entire city. Data processing in this form is a computationally demanding process, but it consists of a large number of mutually independent calculations. Therefore the goal of this thesis was to perform optimization using parallelization. In parallel processing, calculations can be divided between multiple threads, enabling all available computing resources (CPU cores) to be fully used. This concept was practically implemented in the Smart City project of Logimic company. However, the project is built on the Node.js platform, and when using parallelization there are complications with the use of libraries for object-relational mapping (abbr. ORM). ORM libraries on the Node.js platform are not always ready to work in a parallel environment. This problem is solved by creating a separate instance of the used library for each parallel thread. The thesis focuses on reducing the overhead associated with this and also on the correct distribution of work between parallel threads so that all cores are used equally. The results of this work prove that optimizing IoT data processing using parallelization leads to a significant speedup that conforms to Amdahl's law, as overhead problems can be reduced to a negligible minimum.
User Location Interpretation Based on Location Data
Ligocká, Alexandra ; Hynek, Jiří (referee) ; Firc, Anton (advisor)
V tejto práci sa skúmajú kľúčové princípy získavania, spracovania a interpretácie geolokačných údajov s cieľom získania sémanticky zaujímavých miest používateľa. Geolokačné dáta majú obrovský potenciál pre rôzne aplikácie, vrátane reklamných systémov, odporúčaní miest a podobne. Práca sa tiež zameriava na identifikáciu výziev pri extrahovaní domovskej a pracovnej polohy používateľov zo surových GPS dát zozbieraných z GPS zariadení. V práci sa ďalej vysvetľuje dôležitosť sémantického obohatenia miest používateľa. Medzi hlavné diskutované výzvy patrí detekcia zastávok z GPS stôp, identifikácia miest s vysokým významom pre používateľov, extrakcia navštívených miest a ich sémantické obohatenie a interpretácia pomocou aktuálnych mapových podkladov.

System for Smart Central Heating Regulation
Sikula, Jakub ; John, Petr (referee) ; Hynek, Jiří (advisor)
The goal of this bachelor's thesis was to design and implement a central heating control system with a focus on the control of individual rooms. This system is remotely controlled by the Logimic Smart City platform and automatically regulates the heating in an adaptive way. This method brings significant savings to households that are equipped with such a system. This solution differs from existing solutions mainly in that we enter the desired room temperature into the system and the system controls the heating elements so that they reach and maintain the desired room temperature.
API Testing on Smart City Platform
Kovalski, Martin ; John, Petr (referee) ; Hynek, Jiří (advisor)
The IoT environment involves a large number of sensors that produce vast amounts of data. This data needs to be processed and displayed to users. Various clients (web or mobile applications) are created for this purpose. In order to get the data to these clients, application interfaces are needed. The aim of this work is to test an existing REST-like application interface that allows data transfer from the cloud to client applications and to provide endpoint developers of this API with a tool that will allow them to test emerging endpoints in the future. To this end, an application has been created to facilitate the management and creation of tests. These tests are then run using the Codeception testing framework. The resulting application allows you to test a REST API that has an OpenAPI specification created and that uses a PostgreSQL database to run.
