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.
Interface for Automatic Tests of Geovisto Library
Dohnal, Lukáš ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
The aim of this master thesis is to design and implement an interface for automated testing the Geovisto library. The interface should allow efficient and user-friendly testing the library during its development. The thesis includes a survey of libraries to test projects in programming languages JavaScript and TypeScript. The thesis includes the development of tests of current modules of the Geovisto library and the library profiling, which will be used to propose possible changes in the implementation to improve library performance.
Knowledge Discovery from Time Series
Krutý, Peter ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This thesis is focused on the field of knowledge discovery from data, specifically from time series. Main objective is to research Python programming language support in this area and then design and implement an application that will allow to demonstrate and compare selected methods. Methods are demonstrated in experiments using appropriate data set. The output of the thesis is a comparison of methods for specific tasks and the application implementing selected methods.
Framework for Development and Operation of Cloud Services
Hamran, Peter ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
Zložitosť vývoja moderných aplikácií postupne narastá. V tejto práci sa snažím navrhnúť a demonštrovať aplikačný rámec skladajúci sa zo služieb navrhnutých pre cloudové prostredie, ktorý rieši problémy dôležité pre podnikanie. Vytvoril som súhrn existujúcich poskytovateľov cloudových služieb spolu s prehľadom technológií dôležitých pre implementáciu serverovej a klientskej strany aplikácií so zameraním na prevádzku v cloude. Aplikačný rámec je navrhnutý s ohľadom na princípy architektúry mikroslužieb ako distribuovaný systém služieb spolu s fungujúcou demo aplikáciou, ktorá ich využíva.
Reengineering of Two-Tier Applications
Oberreiter, Michal ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
This thesis deals with an analysis of issues regarding reengineering of two-tier applications. Based on the available literature, a comprehensive description of methodology, strategies and approaches is compiled. Relevant software architectures are described, mutually compared and selected problems and their solutions are discussed. As a demonstration of the described methodology, a real-world application was chosen in collaboration with company I&C Energo. This application named Cable Management System is thoroughly analysed and issues concerning the current implementation are identified. Based on the gathered knowledge, a new reengineered cloud-native microservice-based solution is designed and implemented. The result of this thesis is a case study of reengineering application on concrete example of Cable Management System.
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.
Visual Pattern Detection in Web Pages
Kotraš, Martin ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The work solves the extraction of information from websites using the technique of searching for visual patterns - spatial relations between areas on the website and the same visual styles of these areas - with the extension of new techniques to improve results. It uses a user-specified ontological data model, which describes which data items will be extracted from the specified web page and how the individual items on the page look, mainly from a text point of view. As part of the work, a console application VizGet in Java was created using the FitLayout framework to obtain a visual model of the website. Testing the application on 7 different domains, including a list of the best movies, e-shop products, or weather forecasts, showed that the success rate of the application ranges in about 75 % of subtests above 85 % F-score and in more than 90 % of subtests above 60 % F-score, where 45 % of subtests achieve an F-score of 100 %. The VizGet application can thus be deployed for practical use in non-critical applications, while it is open to further extensions and possibilities for improvement.
Web Interface for Managing RDF Data Sets
Kiss, Tomáš ; Rychlý, Marek (referee) ; Burget, Radek (advisor)
The main aim of this thesis is to provide information about RDF data model. Theoretical part of the thesis represents possible ways of storing RDF data, existing RDF storages and SPARQL query language. Furthermore, there is a brief representation of tools used for creation of client web applications with main focus on the Vue.js framework. Acquired knowledge is used to implement web interface enabling browsing of RDF storage and interactive creation of SPARQL queries.
Monitoring the OpenStack Swift Object Store Using Beanstalk Events
Vasiljević, Nemanja ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
Cílem této práce je vytvořit software, který je schopen monitorovat a publikovat notifikace o události z Openstack Swift i z OpenIO Software-Defined Storage (SDS) do fronty Beanstalk. Tato práce také navrhuje řešení pro publikování notifikaci o událostech z MinIO do fronty Beanstalk. K dosažení tohoto cíle je navržen nový middleware, který lze spouštět uvnitř pipeline proxy serveru v OpenStack Swift a uvnitř pipeline OIO-Swift serveru v OpenIO SDS. Navržený middleware umožňuje uživatelům určit, zda mají zájem o publikování notifikaci o události pro konkrétní objekty/kontejnery pomocí metadat. Uživatel může specifikovat sadu pravidel zahrnující vlastnosti objektu, jako je název (prefix, přípona, podřetězec) a velikost, a budou publikovány pouze události splňující tato pravidla. Přínosem této práce je unikátní software schopný monitorování událostí z OpenIO SDS i Openstack Swift.
