Management, Retrieval and Access to Electronic Theses and Dissertations
Mach, Jan ; Bratková, Eva (advisor) ; Strossa, Petr (referee) ; Souček, Martin (referee)
The dissertation is devoted to analysis of current practice and trends in providing repositories of electronic theses and dissertation (ETDs) in terms of their management, searching and dissemination. The first part presents terminology and the current state of access to ETDs in Czech and foreign repositories and includes results of a survey of the state of access to ETDs in the Czech Republic which was completed in 2014 by all public universities. In the second part, a metadata standard is presented, particularly the possibility of mapping EVSKP-MS metadata elements to other metadata formats and utilization within the OAI-PMH protocol. The issue of access to ETDs is dealt with further in terms of metrics for an evaluation of usage of distributed ETDs. Searching for ETDs is also described in case studies as are recommendations for public tenders for a discovery service and for creating an ETD metadata search server and an associated user interface with faceted search. The final part of the thesis focuses on the issue of plagiarism. This incorporates a presentation and analysis of the most important plagiarism detection systems and a case study of the development of the portal Validátor VŠE to provide access to results of document analysis.

3D Audio Standards in Home Theatre Environment
Kováč, Daniel ; Schimmel, Jiří (referee) ; Balík, Miroslav (advisor)
This work deals with object-based sound. There is a description of the difference between channel-based and object-based sound and the development of this sound to today's form. Subsequently, formats that work with objects are described, and they are compared with each other. MPEGH-3D Audio format is specified here, which is a standard today, and also the method of positioning the virtual audio source by vector-base amplitude panning. It also describes how an encoder and decoder supporting speaker configurations 5.1.2, 5.1.4 and 7.1.4 has been developed according to the MPEG-H 3D Audio specification. Lastly, the work deals with the problem of panning the object sound to the standard configuration and there is also a mention of the listening test.

Traffic detection and analysis using SSL/TLS
Hutar, Jan ; Dvořák, Jan (referee) ; Smékal, David (advisor)
This diploma thesis deals with a detection and analysis of secure connections of electro- nic communication through SSL/TLS protocols. The thesis begins with introduction to SSL/TLS protocols. Thereafter, an analysis of messages used to establish secure con- nections using STARTTLS and postal protocols SMTP, POP3, and IMAP was made. Metadata detection and extraction of secured simplex and duplex connections take place using deep packet inspection tools. The tool of choice is the nDPI library from the Ntop project. The library was extended to detect the connections and extract the metadata based on studies and analysis of transmitted messages. Finally, testing is performed on a training data set and a basic analysis of acquired metadata is made.

Technical metadata for still images
Twrdý, Přemysl ; Bratková, Eva (advisor) ; Hutař, Jan (referee)
This bachelor thesis presents still images from technical metadata point of view, which are used nowadays to communicate images. The NISO standard ANSI/NISO Z39.87 from 2006 (MIX) is presented in detail. Commented examples of metadata records in XML structure show practical use in digital information systems. Finally, in the Conclusion all gathered information is summarized and prospects of using this standard in the Czech Republic are outlined.

Digitalization, metadata description and metadata formats
Hutař, Jan ; Kalkus, Stanislav (advisor) ; Bratková, Eva (referee) ; Sklenák, Vilém (referee)
(EN) This thesis is dedicated to the processes of digitization and metadata description, as well as the links that connect them. In recent years, another topic has been becoming relevant for both mentioned processes - the logical long-term preservation of digital objects. Long-term preservation is dependent on metadata and therefore on the processes of digitization, when some important metadata is created. The first introductory chapter of the thesis briefly describes, with an emphasis on metadata, digitization and theoretical and practical problems of long-term preservation of digital objects. The OAIS reference framework is also analysed, since it is the background for digital preservation and present preservation metadata standards. OAIS is also important for the shape and functionality of digital repositories. Metadata is also the topic of the next chapter of the thesis. General metadata use and its development are discussed, with emphasis on administrative, technical and preservation metadata. The following chapter focuses on the use of metadata in the National Library of the Czech Republic. It describes the evolution during two periods leading up to the present. This section includes comments on how long-term preservation has been reflected in used metadata standards. The second-to-last part...

Automatic publication of data and metadata for map and catalogue systems from raster sources in PostgreSQL
Hettler, Jakub ; Brůha, Lukáš (advisor) ; Grill, Stanislav (referee)
Automatic publication of data and metadata for map and catalogue systems from raster sources in PostgreSQL Abstract The main goal of the presented work is the design and implementation of the application for the automatic publication of the raster data and metadata from the PostgreSQL database to the map and catalog services. The application should exclusively utilize the open source software and technologies. The fundamental component of the developed application is the PostgreSQL database with the PostGIS and PostGIS raster extensions. The presented work evaluates the possibilities of the raster storage from different points of view -e.g. the suitability for the further data processing or the publication of the raster data. The most suitable structure for raster storage is then proposed with respect to analytical and publication usage of the stored data. The possibilities of the open source software for the solution and implementation of the presented problem are then inspected. The GeoNetwork and GeoServer are utilized as a metadata and map server solution. The results of the deployment of these technologies is then evaluated for the real world data and compared with other available related solutions. Keywords: PostGIS, PostGIS raster, GeoServer, GeoNetwork opensource, metadata, web map services, OGC,...

Digitization of 2D objects in museum collections
Wenzl, Jonáš ; Vaněk, Jiří (advisor) ; Stočes, Michal (referee)
The thesis focuses on the analysis of digitization of two-dimensional objects and determination of methods applied to the collection in the Krkonoše Museum in Vrchlabí. The first part introduces and explains the theoretical basis. The second part contains an analysis of the digitization project in the Krkonoše Museum, compilation of methods from checking the object to its saving to data storage. Using the analysis, the main benefits and risks of digitization are ascertained. In conclusion, the digitization project of the Krkonoše Museum is assessed with the emphasis on the practical experience in the digitization of two dimensional objects, the possibilities of digitized collections and suggestions for further implementation. The solution provides
a secure way of creating digital copies of objects of cultural and historical value, their archiving and future use of the data. The findings could be beneficial for other digitization projects.
