Clustering of Biological Sequences
Kubiš, Radim ; Burgetová, Ivana (referee) ; Martínek, Tomáš (advisor)
One of the main reasons for protein clustering is prediction of structure, function and evolution. Many of current tools have disadvantage of high computational complexity due to all-to-all sequence alignment. If any tool works faster, it does not reach accuracy as other tools. Further disadvantage is processing on higher rate of similarity but homologous proteins can be similar with less identity. The process of clustering often ends when reach the condition which does not reflect sufficient quality of clusters. Master's thesis describes the design and implementation of new tool for clustering of protein sequences. New tool should not be computationally demanding but it should preserve required accuracy and produce better clusters. The thesis also describes testing of designed tool, evaluation of results and possibilities of its further development.

Data acquisition from a great number of computers using hierarchical summarization
Jelínek, Mojmír ; Novotný, Vít (referee) ; Komosný, Dan (advisor)
This paper deals with IPTV (Internet Protocol Television) transmission of feedback and is showing options and ways of construction, problems and optimalization of signalization protocol. In the beginning are described IPTV and technology terms that this technology uses. Here can be found information about classical TV (Television) transmitting and comparing with IPTV technology, the advantages and disadvantaged of IPTV and answers why this solution has future. Next parts are about history of IPTV and real use over ADSL (Asymmetric Digital Subscriber Line) in present. Here are explained all the necessary units like Head-End, feedback target, root feedback target, ADSL, DSLAM (Digital Subscriber Line Access Multiplexer) and methods of data stream transmission. Also here are described the techniques of video stream compression (MPEG-2 and MPEG-4) and all options of data transmission as broadcast, unicast and multicast. Important part is about transmission speed and needs. The realization also contains applications, written in the C++ language, for transmitting and receiving packets by UDP (User Datagram Protocol) protocol. The task of these applications is to load the main server, where the measurement of packet loss and CPU (Central Processing Unit) load takes place. The result is a table of measured values for specified packet sizes and for specified time intervals between them. The meaning of this measuring is to find the maximal number of computer nodes, which the feedback target is able to proceed. Last part is about realization of 2 applications in JAVA language, which get the information about end-nodes. Both algorithms are using 2 threads to increase speed of getting the information. The client has few random generators within one thread, which will be later replaced by special algorithms for getting real values.

Web Graphical Visualization of Hierachical Geographical Data
Malý, Vojtěch ; Burget, Radek (referee) ; Hynek, Jiří (advisor)
This work aims to create a tool that can be used in creating web geographic visualizations with the use of hierarchical relationships between geographical objects. This is done for example by disintegration or clustering of various administrative units such as districts or regions based on different zoom levels of the map. This will provide the user with additional options for creating more effective geographic visualizations that can show the displayed phenomena from different angles. Tool will also provide a user interface for downloading the data representation of geographic objects using API and will allow aggregation of data according to individual levels of the hierarchy. This tool is an optional part of Geovisto, which provides tools for the visualization of generic data in web browsers on various thematic maps.

Kafka, Matěj ; Richterová, Magdalena (advisor) ; Syřiště, Ivo (referee)
Work with primary school students is an inseparable part of almost every teacher. This diploma thesis is focused on improving selected methods, based on ethological observations and individual support of selected students. The theoretical part is focused on the presentation of ethology, as well as on the description of individual behavioral phenomena and shaping selected elements of behavior from the point of view of physiology, sociology and psychology. Furthermore, the theoretical part elaborates the description of the observed category of students. The beginning of the practical part is focused on the introduction of the selected institution and an individual description of the observed students. The research part is focused on the ethological observation of the behavior of individual students and the application of support measures. The collected results are supported by case studies and subsequently verified by basic statistical analyses.

Pach vítězství: role feromonů v interakcích raků
MAREŠ, Josef
Analysis of communication, hierarchy, and role of pheromones in crayfish is an interesting area that constantly brings new knowledge and can help us understand some facts that may be valid not only for crayfish but also other crustaceans. In this work, it was therefore studied how the offspring of two females behave in a one tank. After the dominance establishment in females (after a series of contacts and fights), the offspring of preferred a dominant female only, regardless of if their own or a unfamiliar mother. The dominant female, that successfully fought the fights, collected juveniles by its active movement, and they followed its movements. The subordinate female accepted her position, tried to avoid contacts, and reduced its activity. The juveniles practically ignored the subordinate mother at this stage of the experiment. Within the diploma thesis, all set goals were achieved and the newly discovered facts may be an important part of further follow-up experiments. We were able to respond positively to all primary hypotheses when: 1 / Females of marbled crayfish in one tank always established a relationship of the dominant and subordinate one, 2 / marbled crayfish juveniles always chose only one mother in a common tank, and 3 / it was in all cases the dominant one. The results show that dominance (whether communicated chemically or by visual stimuli) is a more important factor for juvenile crayfish than the specific brood pheromeone of their mother. The results bring significant knowledge to the issue of the hierarchy of various chemical and visual signals in crayfish communication. Thus, certain communication signals seem to be superior to others. The "winner odours" are probably stronger than such a strong stimulus as the brood pheromone responsible for recognizing the offspring and the mother. On the other hand, it is not possible to rule out a possible effect of the unattractiveness of the subordinate mother. How the relationships among the subordinate female, dominant female and their offspring would develop in remains opened to further research hypotheses.
