Educational System for Recommending Study Activities
Zapletal, Jakub ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
Cílem této práce je navrhnout a implementovat modul do existujícího doporučovacího systému Open University v Milton Keynes. Nyní nasazený doporučovací systém využívá informací o aktivitě uživatelů ve Virtual Learning Environment (VLE) nasbíraných z předchozích let a podle ní doporučuje studentům relevantní studijní aktivity. Tento modul využívá sémantické podobnosti mezi studijními materiály k doporučení těch, které pomohou uživateli vyřešit úkol nebo které jsou podobné k těm, o něž projevil zájem.K počítání podobnosti dokumentů je využíváno metod Term Frequency - Inverse Document Frequency a vnoření slov.Pro používání modulu a jeho komunikaci modulu s rozhraním OU Analyse je implementováno RESTful API.

Web Interface for a Document Analysis System
Mirská, Olga ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This Bachelor's thesis describes the design and implementation of a web interface for a internet documents analysis system based on existing desktop application FITLayout Framework. The work is divided into theoretical and practical part. The theoretical part describes the technologies used for creating dynamic web pages. The practical part is dedicated to description of design solution and implementation of particular functions of the web application FITLayout. In conclusion the testing results of the web application's functions and their comparation with functions of FITLayout Framework are presented.

Presentations Web Editor
Abrahám, Adam ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The aim of this thesis is to implement a web application to manage presentations with Markdown content, which are then presented through slideshow framework Reveal.js. Frontend of the application is created with Vue.js and Nuxt.js, backend with Express.js and for data storage I have chosen MongoDB, a NoSQL document database. Frontend and backend parts of the application communicate with each other through REST technology. The application allows users to view, edit and create more versions of the same presentation. This thesis furthermore contains description, comparison of current technologies and substantiation of their selection.

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.

A Production Management System in the Form of a PWA
Gladiš, Damián ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This thesis deals with the analysis, design and implementation of a production management system in the form of PWA. The diploma thesis describes the design of this application with a focus on the execution and prioritization of production orders and the record of work documentation and employee errors. The chapters describe the analysis of the above-mentioned requirements, on the basis of which the design and implementation of this system was processed.

Text Classification Methods in the Context of Web Pages
Trstenský, Patrik ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This work deals with the issue of text classification in the context of websites. It examines available classification methods and their accuracy over web page plain text. It deals with constructing a dataset for training these methods for a specific domain. We obtain data for creating the dataset from publicly available websites that utilize RDF documents defined in HTML code. The conclusion of the work consists of the creation of two datasets for two different domains. Furthermore, the use of these datasets for training models and testing of their accuracy.

Checking SQL Code Properties
Bali, Filip ; Bartík, Vladimír (referee) ; Rychlý, Marek (advisor)
This thesis focuses on checking the properties of SQL code based on static analysis using predefined rules. The rule represents a basic element of the check. The user can define their own rule and include it in the check. A rule usually contains a set of conditions that are contained in an algorithm that checks nodes in an abstract syntactic tree. Abstract syntactic tree is created from an input SQL statement and customized so that rules can be applied over its nodes. If the rule detects an error, then it can generate a report. These reports are then displayed on the selected output. Based on the thesis, an open source program in the Python3 programming language was implemented. This program is publicly available.

System for Service Workers’ Routes Planning
Mlčoch, Michal ; Bartík, Vladimír (referee) ; Hynek, Jiří (advisor)
This bachelor’s thesis deals with the issue of service requests arising in smart cities and their planning into the routes for service workers. The thesis discusses the issue of the concept of smart cities, route optimization and analysis of services providing route optimization. This work aims to create a system for planning the routes of service workers for the smart city platform developed by Logimic. The main functionality is to enable route optimization through third-party services, and the emphasis is on being able to easily change the thirdparty service providing the optimization.
