Tubesheet analysis according standards and FEM
Horniak, Patrik ; Vincour, Dušan (referee) ; Pernica, Marek (advisor)
The focus of this master’s thesis is strength design of tube sheet, which is part of shell and tube heat exchanger, with fixed tube sheets. This tube sheet is integrated with both shell and channel of the heat exchanger. First part of the thesis is focused on literature review of shell and tube heat exchangers, tube sheets and calculation standards, which are used for their strength design. The strength design of tube sheet is presented in second part of the thesis, according to the standards: ČSN EN 13445, ASME BPVC VIII and TEMA, along with comparison of these standards. Last section of the thesis deals with the implementation of FEM analysis and its comparison to the analytic approach of strength design, used in accordance to the standards mentioned above.

Implementation of Message Queue as a Service in Cloud Computing
Hanus, Tomáš ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
Thesis discusses about different ways of a communication between components of a distributed system. It describes a communication using a message exchange and at the same time talks about other alternatives. It adds details about various models of a message exchange, various message types and about various specifications as well. Commercial tools ActiveMQ, RabbitMQ and Kafka are presented. Special emphasis is placed on describing the way these tools exchange messages, scalability options and others. The web service is designed according to the described features. Its main purpose is management and monitoring of the tool by user choice and easy replacement of this tool with another one. Designed application is implemented using the Kotlin language for selected tool RabbitMQ. The implemented solution allows a simple exchange of messages through the REST api.

Checking of heat exchanger to flow-induced vibration
Mazura, František ; Pernica, Marek (referee) ; Buzík, Jiří (advisor)
This bachelor thesis focuses on the thermal-hydraulic design of the heat exchanger and flow induced vibrations checking. The introductory part describes the basic distribution and function of heat exchangers. The next part introduces the thermal-hydraulic design in the Python programming language using the Kern‘s method for an U-tube heat exchanger. Thermal-hydraulic design outputs are compared with values from HTRI software. Subsequently, the issue of the flow induced vibrations is characterized and the checking of these vibrations according to the normalized TEMA standard is performed. Finally, the heat exchanger is checked using the Poddar & Polley graphical method.

The influence of agency news from the ČTK on the content of foreign news sections in periodicals
Vančurová, Kateřina ; Trunečková, Ludmila (advisor) ; Francová, Pavla (referee)
The diploma thesis "The Influence of Agency News from the Czech News Agency on the Content of Foreign News Sections in Periodicals" is focused on the thematic a geopolitical focus of the foreign news sections of Czech national dailies in comparison with the agency service of the Czech Newa Agency (CTK). The thesis strives to answer the question, how similar they are. At the same time, work with sources is compared. The theoretical basis for this thesis lies in the theorie of gatekeeping, news values and agenda setting. Two month-long periods were analyzed in the thesis, with emphasis on the comparability of the work with sources. March 2012, a so-called usual month with no expected events of big importance, was compared to the period between 20 October and 20 November 2012, when presidential elections went on in the United States of America. Three hypotheses were determined; of them, two were confirmed and one partially disproved. Powered by TCPDF (www.tcpdf.org)

Biology Textbooks Evaluation from the Perspectives of Teachers
Šindelářová, Kateřina ; Hlaváčová, Lucie (advisor) ; Svobodová, Silvie (referee)
This diploma thesis focuses on selected textbooks used for teaching natural history and their evaluation by teachers who work with them. The work aims to find out teachers opinions on the quality and practical use of natural history textbooks from the publishing house "Fraus, Nová škola - Duha and SPN". The work is divided into two parts. In the theoretical part, the basic concepts related to textbooks are explained, and attention is paid to their evaluation and use possibilities. The research uses a questionnaire survey method to evaluate selected natural history textbooks by teachers. It focuses on specific work with a textbook, on topics that, according to the respondents, are not appropriately treated, and topics that are entirely missing or need not be in the book. The subsequent analysis of the collected data shows teachers' different approaches to using the textbook; some share only selected topics with their students, and homework assignments may also vary. In addition, most teachers think that not all topics are handled correctly, nor are they all genuinely essential. KEYWORDS textbook, natural history, topic, use, Fraus, Nová škola - Duha, SPN

Taboo and noa in communication. Realization of linguistic taboos in the print media
Junková, Anna ; Chejnová, Pavla (advisor) ; Janovec, Ladislav (referee)
Taboo and noa in communication. Realization of linguistic taboos in the print media. This thesis deals with issues of the taboo and noa in language and communication. The core of this thesis is to identify the essential tabooed themes in contemporary society and ways of their linguistic realization in the print media. In the theoretical part of this thesis is the first explained substance of the terms such as taboo, noa, communication and linguistic taboos with regard to the interrelations between these terms. In the empirical part are then defined tabooed themes occurring in the concrete texts of the diary Mladá fronta DNES and Blesk and of the periodical Rytmus života and ways of their linguistic grasping. The thesis focuses above all on the manifestations of speech restrictions in the lexical plan of the language.
