Controling the dust exhaust of smeltery for recyclation of aluminum waste
Jakubský, Ondřej ; Nadrchal, Zdeněk (referee) ; Trnka, Vladislav (advisor)
The work deals with controlling and visualizing technology of dust exhaust of smeltery for recyclation of aluminum waste. In the first part of the work are analyzed the different ways of automatic control. Based on the analysis is proposed control system configuration, algorithm of control, communication interfaces and sensors of alarm, measurement and regulation. The second part deals with visualization and remote administration of control system. On the basis of selection for the visualization software is designed and implemented a system that provides visualization of technology, the archiving of measured operating values, events and errors.

Archived Data Management System
Havlíček, Martin ; Šeda, Miloš (referee) ; Máša, Vítězslav (advisor)
The goal of this work was to research the available database systems and propose a suitable database system for data archiving. Prepare the communication and processing of data between the database and delivered application Profisignal which processes the measured data from all sensors. Design architecture for the database, the storage of measured data and calculation reports on that data. At the end design the web user interface. The result of my work demonstrate possible ways of archiving data in ORACLE database, examples of calculation the reports and sample of web application, that presented the measured data.

Data archiving using blockchain technology
Řihánek, Tobiáš ; Sikora, Marek (referee) ; Člupek, Vlastimil (advisor)
This thesis dealt with the issue of data archiving. The aim was to explore the possibilities of using blockchain technology to address the security aspects of digital archiving, and then to design and implement an application that uses blockchain to secure data integrity. First, a theoretical analysis of both archiving and blockchain technology was conducted. Next, a web application was designed that uses this technology to detect integrity breaches. Based on the design, a system consisting of a web application written in JavaScript and an archiving application and a validation application written in Java was implemented. These applications communicate with each other and create a secure archiving system using blockchain. The functionality of the system was demonstrated and its security was tested.

Ensuring Long-term Data Integrity in Cloud Storage
Nohava, Martin ; Člupek, Vlastimil (referee) ; Malina, Lukáš (advisor)
The subject of the thesis is the design and development of a system to ensure the long-term integrity of data from the Nextcloud cloud storage, which manages and stores electronic evidence. In the introductory part, the terms and principles used for securing data integrity are presented, including quantum-resistant digital signature schemes. Subsequently, the architecture of the archiving system and the method of its connection with the Nextcloud cloud storage are proposed. The resulting system consists of two main components, the Archive application, which extends the web interface of the Nextcloud instance, and the archiving system, which ensures the integrity of the archived files themselves. In addition to time stamps, system also uses a quantum-resistant Dilithium signature scheme. At the end of the work, an evaluation of the implemented solution is carried out by measuring the performance of the archiving system, and options for its further development are proposed.

Archiving Social Research Data from the Viewpoint of Czech Social Science Data Archive
Vávra, Martin
Czech Social Science Data Archive is now an established research infrastructure within the Czech Republic and also it is a part of the European research infrastructure through CESSDA organization. The presentation will address the opportunities and constraints associated with data archiving and sharing in the social sciences. Emphasis will be placed on used standards (for metadata, keywords) and tools (on-line database solution) and on how these standards and tools help to develop a pan-European system of data services in the social sciences.

Distributed power quality monitoring systems
Pithart, Jan ; Macháček, Jan (referee) ; Drápela, Jiří (advisor)
Subject of this master’s thesis deals with the issues parameters of electric power and some possibility of measuring with focusing on norm requiring parameters. There are some distributed power quality monitoring systems described, which are available. The following chapter discusses the suggestion and implementation of the low-cost monitor with remote control for low-voltage networks. The thesis also concerns the using MySQL database for archiving measuring values and implementation of web applications for on-line presentation of the measured values.
