JavaME communication client
Svoboda, Pavel ; Mácha, Tomáš (referee) ; Číka, Petr (advisor)
This diploma thesis deals with developing multimedia applications on Java Micro Edition platform. The aim of this work is to design and implement the application which could establish a call between two users. The first part of the work describes J2ME platform, its two configurations and profiles. Next part is focused on Session Initiation Protocol and Real-time Transport Protocol. The application design consists of choosing the suitable virtual machine JVM, SIP and RTP libraries. The main part of this work describes application structure, graphic user interface and installation packages creating. It also shows a way of customizing the media stack - Java Media Framework, version Cross Platform.

Failure of humanitarian assistance - a case study of Haiti
Hudáková, Miriama ; Zemanová, Štěpánka (advisor) ; Knotková, Vladimíra (referee)
This thesis is dealing with one of the little explored spheres of international relations - humanitarian aid. The paper specifically devotes its failure in three main areas, namely the media, accountability and management of resources and aid dependency syndrome. Its aim is to analyze the possibility of eliminating these errors in the case of Haiti given that these failures were repeated throughout history of humanitarianism. In the present study I also include steps that in the future may contribute to more effective and transparent humanitarian assistance.

Data Mining in Social Networks
Raška, Jiří ; Očenášek, Pavel (referee) ; Bartík, Vladimír (advisor)
This thesis deals with knowledge discovery from social media. This thesis is focused on feature based opinion mining from user reviews. In theoretical part were described methods of opinion mining and natural language processing. Main parts of this thesis were design and implementation of library for opinion mining based on Stanford Parser and lexicon WordNet. For feature identi cation was used dependency grammar, implicit features were mined with method CoAR and opinions were classi ed with supervised algorithm. Finally were given experiments with implemented library and examples of usage.

Video-Conference System for Remote Education
Holán, Josef ; Szőke, Igor (referee) ; Schwarz, Petr (advisor)
The main goal of this thesis is to design videoconferential system by Java Media Framework. This means to write two programs. One will capture multimedia data from webcam and will sent it into network. The second application which can receive this data is supposed to be on another computer. The multimedia data are transmitted by using Java Media Framework library. We suppose one lector and group of students. Video and audio channel is transmitted to all students. Communication between lector and student is solved using chat. Lector has possibility open another audio or video channel with all students. Multimedia data will be transferred using Real-time Transport Protocol (RTP). The message including information about student is transferred by Transmission Control Protocol (TCP).

Synchronized data transfer of signalling in IPTV
Figurny, Roman ; Karásek, Jan (referee) ; Müller, Jakub (advisor)
The task of Bachelor's thesis has been to develop synchronizing mechanism for signaling servers, called Feedback Targets, in hierarchical structure of the feedback tree. Then verify the function of this designed synchronizing mechanism in simulation developed in Java. Using this synchronizing mechanism to shorten the time needed to travel the signaling packets trough the feedback tree and using this to obtain better reaction to possible network junction or significant packet loss while distributing multimedia data while using IPTV. In theoretic part of the thesis there are described basic protocols like RTCP, RTP and TTP. Then are described methods for packet sending in network (multicast, unicast and broadcast). The basic piece of knowledge about IPTV, its distribution and differences between IPTV and classic internet media streaming are described. Also basic terms like Feedback Target, Feedback Target Manager and FTI, FTS and FTD packets are described as well.

City House – Mixet Use Architecture
Martochová, Jana ; Ing.arcg.Pavel Šimeček (referee) ; Menšíková, Naděžda (advisor)
The theme of my disseration is an architecture study of multifunctional building which is surrounded by the streets Vranovská, Cejl and Jana Svobody and by the embankment of the river Svitava. Objective of the study was to design a building that would utilized the space of the plot effectively. The result of design is the construction which is characterized for its inner semi-public atrium space with link to the bank of Svitava and street Jana Svobody. It is five-storey house. In the first two stories there are different feature amenities (kindergarden, office building, restaurant, café, media library, gallery and other shops), and senior house. In the third floor and above there are designed flats for living. The part of the living area was also creating of new kind of housing called co-housing. The building has a basement, which is mostly for parking. The construction of the building is from monolithic reinforced concrete frame, horizontal structure consists of beamless slabs. Due to the huge area of the building, the facade is designed from the different kinds of materials: white plaster, light gray sheet metal, anthracite metail mesh and glass fiber.

Analysis and visualizations of relationships over data from social networks
Jiránek, Aleš ; Šebesta, Michal (advisor) ; Molnár, Zdeněk (referee)
This diploma thesis deals with various types of relations observable in social networks. First part contains survey of existing papers focused on social media data analysis and visualisations. This survey is followed by research of existing visualisation applications. The contribution of this thesis is a new look at relations on social networks, from the side of relationship between users who write posts on any given topic. To visualize these relations was chosen network graph. On the basis of established criteria existing instruments were evaluated and since any of them did not meet all requirements, I created new application for visualising relations. Thesis also includes a description of selection the appropriate libraries for its implementation, explanation of user interface and a summary of configuration options and customization. The end of the work contains analysis and visualisations made with newly-created tool.

XMPP protocol Jabber features and its utilization for multimedia transmission
Havlena, Petr ; Průša, Zdeněk (referee) ; Šmirg, Ondřej (advisor)
Master’s thesis is trying to create opensource IM application for communication in Jabber network. In nowadays it is getting more and more popularity as at providers, so mainly at end users. In first half of thesis are explained basics of whole issues and in second half is described resulting application, which has been created by using of object oriented programming language Java. Java is very extended between programmers for her simplicity and great support. Thanks this is available a many external libraries and extensions. Application has been written on Smack library in version 3.04 and VoIP module on JMF (Java Media Framework). Graphic interface has been created by using of standard Java visual components (javax.swing).
