Web Server for Protein Structure Prediction
Votroubek, Lukáš ; Očenášek, Pavel (referee) ; Burgetová, Ivana (advisor)
This work deals with proteins, especially with their structure and kinds of tertiary, or 3D, structure prediction. Tertiary structure prediction is very important for function prediction of this vitally important substance. Bioinformatics do this prediction much more effective and faster, because classical methods of structure prediction directly from molecule are very expensive and slow. On the other hand they are much more exact. Objective of this thesis is to describe tertiary structure prediction methods, describe used tools and possibility of automatic communication with them. Next objective is describe implementation of server, that will serve to protein engineers for more effective finding of information about tertiary structure from more servers without requesting each of them separately. Results of testing will be described in this work too.

Videoconferencing Application
Jandera, Pavel ; Šmirg, Ondřej (referee) ; Číka, Petr (advisor)
Videoconferencing is a modern way of communication, in which the participants carry picture and sound and during transmission can also exchange various data. The aim of this work is to create an application for the connection of up to eight participants to videoconferencing and create a web interface to facilitate configuration of this application. Videoconferences types and the feasibility are described in the first part of this work. Furthermore, the SIP (Session Initiation Protocol) protocol used to production of multimedia sessions is described. RADVISION IVP system was selected to the implementation of videoconferencing application. IVP is a complex system for the operation of videoconferencing, which allows implementing and operating various types of services. Basic components of system are described in next section of this work. Second part of this work describes interface for applications creating that IVP offers to programmers. The main part of this work is the design and implementation of video conferencing application that is realized as an IVP service. There is described the implementation and testing. A web interface to facilitate the configuration of video conferencing applications has been designed and implemented. This interface also allows the service provider to manage user accounts. The web interface was implemented in Java EE.

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.
