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.

The diploma thesis titled Transformation of Journalistic Practices Relating to Advent of Data Journalism concerns the current situation in Czech data journalism and its devel- opment. It examines how the newsroom, the journalists and the readers cope with new technology, big data and the related advent of data journalism. The theoretical part of the text explains the relationship between classical journalism and data-driven journal- ism and compares the so-called "narrative" and "interactive" approaches as forms of data-driven journalism. Further it gives a deeper understanding of the relation between data journalism and the new concept of objectivity and it deals with the cultural, social and technical preconditions of data journalism. The thesis also describes the historical aspects of the topic comparing computer-assisted reporting to current practice. Sub- sequent chapters deal with the visualizations, infographics, amateur data journalism and open data which all play a key role in data-driven journalism. The practical part intro- duces the Czech data team. It was originally established within the publishing house Economia and then moved to the office of Czech Radio (Český rozhlas). The final parts discuss the cooperation model of the Czech data team, the use of visualization in their projects,...

However, many LMSs does not have a mechanism or tool to aid the teacher to get detailed information about the social interaction between students and their group. This complicates the teacher’s awareness with regard to social relations established within the discipline. Based on this information, this paper proposes and details an approach to this problem that makes use of a Multi-Agent System architecture directed to the analysis of the interactions of groups. As proof of concept, a prototype was developed as using a software methodology for Multi-Agent Systems in order to analyze the interactions between students that occurred in the forums and messages of a course in the LMS Moodle and present this information to the teacher in the form of sociogram or table. In this way, the teacher can visually monitor the interactions of students within the course, and adopt tactics that promote social inclusion. To validate the work a case study was performed, a class of a course of Distance Education in a Higher Education Institution (HEI). According to the results obtained in simulated tests and a real class, it is clear that the graphic visualization of interactions of students in the forums and messages, when combined with the proactivity of agents, can corroborate the work done by mediators. The vizualization of the interactions provides to the teachers a more comprehensive, clear and quick view of social interactions established in the discipline, facilitating a option to intervene intentionally through teaching strategies such as to encourage students to develop the communication, interaction and the creation of new groups. / A crescente utilização de Ambientes Virtuais de Aprendizagem (AVA) como disseminadores do conhecimento auxilia os alunos na construção do saber e proporciona uma interação entre as pessoas via ferramentas computacionais mediadas pelo professor (mediador ou tutor). Contudo, muitos AVAs não possuem um mecanismo ou ferramenta para auxiliar o professor a obter informações detalhadas acerca das interações sociais dos alunos e dos seus grupos. Isso dificulta a percepção por parte do professor no que diz respeito às relações sociais estabelecidas dentro da disciplina. Com base nessas informações, o presente trabalho propõe e detalha uma abordagem para esse problema que faz uso de uma arquitetura de Sistemas Multiagente voltada para a análise das interações dos grupos. Como prova de conceito, um protótipo foi desenvolvido a partir de uma metodologia de software para Sistemas Multiagente, com o objetivo de analisar as interações entre os estudantes que ocorreram nos fóruns e nas mensagens de um curso no AVA Moodle e, apresentar essas informações ao professor sob a forma de sociograma ou tabela. Desta forma, o professor pode acompanhar visualmente as interações de seus alunos dentro do curso e adotar táticas que promovam a inserção social. Para validar o trabalho, foi realizado um estudo de caso como avaliação de viabilidade, numa turma de um curso de Educação a Distância (EaD) de uma Instituição de Ensino Superior (IES). De acordo com os resultados obtidos nos testes simulados e com uma turma real, pode-se concluir que a visualização gráfica das interações dos alunos nos fóruns e nas mensagens, quando aliadas à proatividade dos agentes, pode corroborar o trabalho desempenhado pelos mediadores. A visualização das interações proporciona aos docentes uma visão mais abrangente, clara e rápida das relações sociais estabelecidas na disciplina, facilitando a opção de intervir intencionalmente por meio de estratégias didáticas, tais como incentivar os alunos no desenvolvimento da comunicação, na interação e na criação de novos grupos.

This thesis studies the influence of internal nozzle flow characteristics over a large spectrum of experimental conditions and diagnostics. Experiments were carried out for two nozzle geometries---cylindrical and conical single hole nozzles---and three different fuels. Two of the fuels are pure components---n-heptane and n-dodecane---while the third fuel consists of a three-component surrogate to better represent the physical and chemical properties of diesel fuel. Measurements include a complete hydraulic characterization consisting of instantaneous injection rate and spray momentum flux measurements; a high-speed visualization of isothermal liquid spray; a high-speed visualization of the evaporative inert spray, imaging liquid and vapor phases simultaneously and finally, a high-speed visualization of the high temperature reactive spray, imaging vapor phase and OH* chemiluminescence for each injection event. All high-temperature diagnostics were performed in a continuous flow test chamber that allows an accurate control on a wide range of thermodynamic conditions (up to 1000 K and 15 MPa). The experimental findings from this work, and the large database obtained (available for download at: http://www.cmt.upv.es/DD01.aspx), could be used to validate CFD models that could help the community understand the fundamental driving mechanisms behind these observations. / En esta tesis se estudia la influencia del flujo interno sobre un amplio espectro de condiciones y diagnósticos experimentales. Se realizaron experimentos para dos geometrías de tobera---toberas cilíndrica y cónica de un único orificio---y tres combustibles. Dos de los combustibles son puros---n-heptano y n-dodecano--- mientras el tercero es un combustible sustituto que consiste en una mezcla de tres componentes que busca representar mejor las propiedades físicas y químicas del diesel. Las medidas incluyen una caracterización hidráulica completa, compuesta por tasa de inyección y cantidad de movimiento instantáneas; una visualización de alta velocidad del chorro líquido isotermo; una visualización de alta velocidad del chorro inerte evaporativo, con captura simultánea de las fases líquida y vapor y, finalmente, una visualización del chorro reactivo a alta temperatura, con captura de la fase vapor y la quimioluminiscencia del radical OH* para cada evento de inyección. Todos los diagnósticos en condiciones de alta temperatura fueron realizados en una maqueta de alta presión y temperatura de flujo constante que permite controlar con precisión un rango amplio de condiciones termodinámicas (hasta 1000 K y 15 MPa). Los resultados experimentales y la gran base de datos obtenida en este trabajo (disponible en: http://www.cmt.upv.es/DD01.aspx), podrían ser utilizados para validar modelos CFD detallados que podrían ayudar a la comunidad científica a entender mejor los mecanismos fundamentales que producen los resultados observados. / Aquesta tesi estudia la influència del flux intern sobre un gran espectre de condicions i diagnòstics experimentals. Es van realitzar experiments per a dos geometries de tovera---toveres ci¿líndrica i cónica amb un únic orifici---i tres combustibles. Dos dels combustibles són purs---n-heptà i n-dodecà--- mentre el tercer combustible consisteix en una mescla de tres components que formen un combustible substitut que busca representar millor les propietats físiques i químiques del dièsel. Les mesures inclouen una caracterització hidràulica completa, composta per taxa d'injecció i quantitat de moviment instantanis; visualització d'alta velocitat del doll líquid isoterme; visualització d'alta velocitat del doll inert evaporatiu, capturant simultàniament les fases líquid i vapor i, finalment, una visualització del doll reactiu a alta temperatura, capturant la fase vapor i la quimioluminiscència del radical OH per a cada esdeveniment d'injecció. Tots els diagnòstics en condicions d'alta temperatura van ser realitzats en una insta¿lació d'alta pressió i temperatura amb flux constant que permet controlar amb precisió un ampli rang de condicions termodinàmiques (fins a 1000 K i 15 MPa). Els resultats experimentals i la gran base de dades obtinguda en aquest treball (disponible a la web en: http://www.cmt.upv.es/dd01.aspx), podrien ser utilitzats per tal de validar models CFD detallats que podrien ajudar a la comunitat científica a entendre millor els mecanismes fonamentals que produeixen aquestes observacions. / Viera Sotillo, JP.
