Graphics and Presentation in the TeX and LaTeX Systems
Buňka, Roman ; Sysel, Petr (referee) ; Rajmic, Pavel (advisor)
This bachelor’s thesis deals with the insertion of external graphic files into LaTeX documents and the creation of graphics using internal tools of TeX. It describes the basic properties of the PSTricks additional package and its expansion enabling the creation of 2D and 3D graphs, special mathematical functions and electrical circuits. The work deals also with the method of creating PDF presentations using the Beamer class. This work suggests a structure of a source SVG file displaying electric circuits or flow charts. It also involves the creation of an XSLT conversion template providing for the conversion of these charts from the SVG format to the PSTricks format making it possible to use these graphic files in the LaTeX system.

Visualization of relations between computers in the Internet
Cimbálek, Přemysl ; Malý, Jan (referee) ; Komosný, Dan (advisor)
Internet Protocol Television (IPTV) transmits the television signal over the TCP/IP family of protocols. Its advantages are for example that the transmitting is not only one-way as in the “classical” TV broadcasting, but it can provide feedback such as interactivity. There are also some problems which avoids development, for example low channel capacity of access networks. That is why new methods , for example how to get more efficiency in IPTV transmission, are proposed. The main task of this diploma thesis is to visualize tree structure of relations between nodes in the network, based on understanding of principles of the hierarchical summarization and IPTV transmitting. The nodes in the tree structure provide computing and summarizing of the data in back-way channel. There is the data from the end users in this channel. In the first part of this diploma thesis there is explained the principle of IPTV and its differences as compared with classical TV broadcasting. The part is also aimed for the supported services, advantages and disadvantages. There is explained the compressing data with the MPEG-2 and MPEG-4 standards and problems with transport networks called “last mile problem.” To transmitting data IPTV uses Source Specific Multicast – every user connects to the multicast session with requested TV program. Feedback is provided by unicast. Feedback network uses the hierarchical summarization principle to reduce the data. This problem, connected with RTP, RTCP and TTP protocols, is in the work described as well. There is an international experimental network called PlanetLab mentioned in theoretical part of this work. Proposed structure of new protocol and applications including the visualization for IPTV broadcast, is tested in that network. In the practical part of this work there are discussed possibilities and methods for the visualization and data storage. Because of high availability and flexibility, there were chosen web technologies, such as MySQL for data storage. The tree model is executed by Java. The visualization is solved by web technologies, source code for visualization is dynamically generated by scripts in JSP (Java Server Pages). Graphical output is provided by the vector format SVG (Scalable Vector Graphics) which is created for graphical expression on the internet and in the mobile phones. There were created interactive web application thanks its ability to cooperation with Javascript technology. This application visualizes relation-tree structure of nodes. In this work there are explained basics of all used technologies, there are also given reasons for chosen methods and formats. Examples and interesting parts of solution are mentioned as well.

Analysis of websites' responsive design
Ronovský, Jan ; Vojíř, Stanislav (advisor) ; Hradil, Jiří (referee)
The thesis is about current technologies and optimalization used in developing responsive websites. It summarizes current state and gives small prediction where the future of responsive design is going. This is analysed on 4 news websites ihned.cz, novinky.cz, blesk.cz, extra.cz which are analysed from point of view of areas, which have major influence on user's surfing experience. Websites are compared to each other using criteria, which correspond to each of those areas. Thesis also proposes a solution to each of the bigger mistakes, which each website makes. Those mistakes are in the coclusion put in context of other websites and used to reach a general recommendation, which solutions correct them and are therefore suitable to use in development of any responsive websites in the future.

SVG technology and HTML 5 Canvas object as perspective methods of inserting dynamic graphics into web pages
TRANTÝR, Tomáš
In my thesis, I deal with comparison of SVG technology and HTML5 Canvas object for insertion of dynamic graphics on web pages. Thanks to continuous development of web browsers and especially thanks to the usability of dynamic elements, those techniques are being supported and used increasingly among the Internet. My work describes principles of creation of dynamic graphic elements with use of both methods mentioned earlier, clearly analyse their advantages and disadvantages as well as the suitability of utilization in real situations. Also a set of original examples demonstrating the use of SVG and Canvas in practice is a part of my work, which should bring the audience even closer to those environments and their functionality. The functionality of both technologies in current versions of wide spread web browsers was tested as well.

Visualisation of musical notation using XML technologies
Vacek, Matěj ; Kosek, Jiří (advisor) ; Šimůnek, Milan (referee)
This thesis focuses on the visualization of musical notation. Even for such a small group of data, there is a specification (MusicXML) which can be used for converting between different softwares. The development of musical notation has been going on for centuries and it has become very complex by now, because composers want to express all their thoughts. Therefore, I have decided to limit the supported part of musical notation and in this thesis, I will focus only on the area of simple Czech folk songs, which have their own specifics. The songs will be displayed in SVG format. This format is based on vector graphics. Transfer between the original and SVG file will be implemented by using XSLT transformation, which is created in this thesis. As far as I am concerned, there is no such already existing transformation.

XML Schema Visualization
Slavětínský, Václav ; Kosek, Jiří (advisor) ; Ralbovský, Martin (referee)
Bakalářská práce se zabývá návrhem a implementací aplikace, která slouží k převodu W3C XML schémat do interaktivního diagramu ve formátu SVG (Scalable Vector Graphics). Diagram poskytuje údaje získané ze schématu ? údaje o elementech a atributech, a jejich přípustné struktuře. Proto je vhodný jako součást dokumentace XML souborů vyhovujících schématu. Generovaná grafika je interaktivní a přehledná, uživatelům má usnadnit pochopení XML dokumentů a orientaci v nich. Aplikace je napsána v jazyce Java, využívá implementaci abstraktního datového modelu z open source XML parseru Xerces2-J. Interaktivita SVG výstupu je zajištěna ECMAScriptem.

Interactive Visualisation of RELAX NG Schemas
Sýkora, Lukáš ; Kosek, Jiří (advisor) ; Ralbovský, Martin (referee)
The aim of this thesis is to create a tool for visualisation of RELAX NG schemas. RELAX NG schemas define a form of XML documents. They determine what elements and attributes can be used in the document and how they can be combined. Visualisation of schemas enables easier orientation in the structure of RELAX NG patterns. This can be useful for both developers of schemas and users who use schemas for creation of XML documents. RELAX NG schema can be written using XML, which enables its visual representation by means of tree structure. Moreover, the model of the tree is interactive which enables users to display only the branches they are interested in. The aim will be reached in several steps. At first, it is necessary to analyze properly the structures of RELAX NG language with respect to their future visualisation. Next step is SVG format for description of vector graphics. SVG format can be written using XML as well. Interactivity of the model described by SVG is enabled by ECMAScript. The conversion from RELAX NG to SVG graphics will be done by means of XSLT transformation. The main contribution of this thesis will be the visualisation which facilitates the orientation in the schema for both users and developers. Only XSLT processor and a file with XSLT transformation will be needed for the visualisation of RELAX NG. The file with XSLT transformation will be the output of this thesis. The thesis is divided into three main parts. The first part is focused on the analysis of the structures of RELAX NG language and the possibilities of their visualisation. Particular attention will be given to the current possibilities of graphic interpretation of schemas. The second part is devoted to the design of graphic symbols for individual nodes of the graphic model and the possibilities of their interaction. The third part deals with the prototype implementation of transformation of RELAX NG to SVG graphics.
