Web Interface for Task Management and Monitoring on a Supercomputer
Bukovinský, Denis ; Jaroš, Jiří (referee) ; Jaroš, Marta (advisor)
One of the goals of the project was to complete the web interface for applications that access the k-Dispatch database, which monitors both running and scheduled tasks on a supercomputer. Another goal was to create a web-based graphical interface for the system administrator using already implemented web interface. Using this graphical interface, the administrator can manage and supervise the system. After studying the web interface specification, I implemented the required functionality that I integrated into the k-Dispatch system. The admin interface will include functionality based on the use-case diagrams that I created from the Web interface specification. This interface uses the k-Dispatch web interface to access the database. The web interface was implemented in Python using microframeworks. The admin part of the application consists of dynamic web pages created using HTML, cascading styles and JavaScript. The server generates these dynamic pages using pre-created templates.

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.

Conference System for Excel@FIT
Kobelka, Martin ; Szőke, Igor (referee) ; Veigend, Petr (advisor)
The main goal of this thesis is to initially conduct a detailed analysis of the issues related to organizing scientific conferences while focusing on the workflow of the Excel@FIT conference and subsequently mapping the workflow of several other conferences organized in the field of information technology in the theoretical part. Then, in the practical part, the task is to design an information system specifically for the Excel@FIT conference and implement it in the form of a web application. The resulting web application for conference administration is developed using the programming languages PHP and TypeScript. The client side is designed as a single-page web application that communicates with the server side through REST API. The application ensures efficient and smooth conference management, registering and reviewing papers and generating exports for evaluation committees. The output is a fully functional application that has been tested on data from previous years and can be easily extended with new functionalities if needed.

Design of a Database Neutral OR Mapper in C++
Ježa, Pavel ; Ráb, Jaroslav (referee) ; Ryšavý, Ondřej (advisor)
This diploma work deals with design and implementation of the database neutral object-relational (OR) layer in C++ language over inherited database. The goal is to create the layer to encase the access to database from the application layer. Suggested layer will stem from the object-relation mapping technology, which is currently available for many object-programming language, such as C#, Java or Visual Basic. The work consists of three main parts. The forepart is focused on clearing object-relation mapping technology. It briefly overviews differences in capabilities and levels of implementation of various approaches. The next part describes significant properties of databases considered as back-ends for data storage in the project. The aim of this part is to present enough information to support database neutral design of the OR layer. The rest of the document deals with design and implementation of OR layer for the considered environment followed by the summarization of results and overall evaluational.

Application for Hand Corrections of Automatically Processed Data
Coufal, Zdeněk ; Beran, Vítězslav (referee) ; Szőke, Igor (advisor)
The objective of this bachelor thesis is to create application for hand corrections of automatically processed data. Thanks to this application it will be allowed to visitors of portal SuperLectures.com to correct text transcripts of slides or audio of the current segment of the lecture. If they decide to help, they will be redirected to the Annotation portal as this application was called and they will be assigned an elementary job to correct representing the given part of the lecture. At first informal analysis is performed, looking for possible tools and procedures for realization. After that requirements are formally specified and later the application design is based on them. Application is implemented according to the design with use of selected tools and procedures. In conclusion, the application is tested and test results are evaluated.

Comparison of Properties and Performance of Object Oriented Databases
Kozák, Daniel ; Burget, Radek (referee) ; Zelený, Jan (advisor)
In this thesis, the reader learns basic models, which are use for storing data in database sys- tems. Next I describe a way, how to store objects in Java Language and explain expressions like object-relational mapping, reflection and introspection. After that, I will introdice some of existing implementation, which are use for storing objects in Java. Next I will explain testing methodology and make benchmarks of various implementation. In the end I will analyze a results of these benchmarks.

Web Application for Suctions, Companies Search and Evaluation
Kürti, Szabolcs ; Jirák, Ota (referee) ; Ruttkay, Ladislav (advisor)
This Bachelor's Thesis deals with creation of information systems. The aim of this project was to create a usable web portal for auctions, company search and evaluation. This paper contains a detailed analysis on requirements, the main concept and implementation of the solution. In this thesis I also present how can developers benefit from the usage of spiral model of software development. The system was implemented by the following technologies: C#, ASP .NET, LINQ, object-relational mapping and JavaScript.

Object-Relational Framework for PHP
Hudec, Michal ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
The objective of this work is to design and implement an Object-relational framework for PHP. This framework will be able to map objects to traditional relational database tables. In this work, an appropriate solution of metadata specification is presented. These metadata describe how an object can be store in a relational database. The framework itself is able to store, load and query any object data in relational database. This object-relational framework has been designed for simple portability among various database systems.
