State of the art on lightning activity induced by volcanism
Tesař, Matouš ; Popová, Jana (advisor) ; Křížek, Marek (referee)
The thesis presents a state of the art of existing knowledge and findings related to the lightning inducted by volcanic activity. First the thesis briefly characterizes lightning which occurs in thunderstorms. The chapter also presents mechanisms of lightning occurrence and methods of lightning detection. The main part of the thesis contains a literature review on the characteristics of lightning which occurs in relation to volcanic activity. It also provides classification of volcanic lightning and mechanisms of its occurrence. Furthermore, the chapter describes methods which are used to detect volcanic lightning. It also contents methods of investigation of volcanic lightning and laboratory experiments, which aim at deepening theknowledge on this phenomenon. Moreover, the chapter also provides a brief outline of expected future research on volcanic lightning. The thesis presents several ways by which volcanic lightning affects the Earth's atmosphere and surface, and the affected volcanic ash particles. Based on findings provided by the literature, the thesis discusses and compares lightning produced during in thunderstorms with volcanic lightning. Key words: lightning, volcanism, state of the art, detection

Biological and related theories of aggression and its humoral regulation
Bradáč, Ondřej ; Komárek, Stanislav (advisor) ; Havlíček, Jan (referee)
Aggression is a phenomenon which acquired a substantial share on attention of biological literature, especially since the beginning of 20th century. In this thesis, various approaches to the problem from the field of biology are summarized. Intensified attention is dedicated to the theoretical concepts of aggression, especially the concepts consulting the problem of aggression from the evolutionary point of view and to the research on the field of hormonal regulation of aggression, stressing out the role of the hormone testosterone, and to particular hypothesis, which take account on its mutual relationship with behavior. The empirical part of the thesis is dedicated to verification of premises of the challenge hypothesis according to the relationship between testosterone and aggressive behavior. Significant findings of the empirical part refer to the existence of a link between basal level of testosterone and aggressive tendencies and to the existence of a negative link between basal level of testosterone and its increase in reaction to a competitive situation.

Analysis of Information Sources for Development of Software Application for Printing Industry
Urbánek, Matyáš ; Basl, Josef (advisor) ; Lipková, Helena (referee)
Diploma work is targeted on analysis and description of information sources for software application and management information systems in printing industry. At first information needs and information overloading are shortly defined. Next are descripted concepts of printing industry, software for printing industry and relatives concepts of management information systems and workflow systems. In next chapter keywords for information retrieval was arranged in hierarchical tree structures. Core specialised journals and usefull information sources were found within information retrieval. In work are involved both deep web sources and surface web information sources. Found information object are descripted and cited by ISO 690. At the end of work are given categorised bibliographic lists and simple web page project for specialised information portal.

Specialized questions in education for elementarists
Švandrlíková, Martina ; Kafková, Helena (advisor) ; Hůla, Zdenek (referee)
This graduation theses deals mainly with theoretical themes. It deals with issues of art selected from the selected literature, works of art, Internet resources and empirical research probe. This thesis consists of two parts, the theoretical and practical one. The theoretical part consists of chapters that result from the mapping of three selected areas - identity, space and time. The practical part is focused on realization of two creative tasks that are based on art issues selected from the theoretical part of the text. One part of the text is also a reflection that deals with the nature of the area of thought, as stated in the literature studied, focused on the teaching primary schools.

Overview of continues variable transmission design
Fryčar, Michal ; Dočkal, Kryštof (referee) ; Šperka, Petr (advisor)
Friction variators are used in many industries mainly for their ability to continuously change the engine-to-output gear ratio while machine is running. In this paper, six types of construction were described (using a belt, chain, ball or toroidal, conical and disc wheel). Their properties were then compared based on the maximum transmitted power and transmission efficiency. The results calculated using Hertz's theories shows, that belt, chain and toroidal constructions are transmitting the highest amount of maximum torque. These results are in accordance to earlier studies in this field and they are intended to serve as a source of information for further research on topic.

Optimization of parking spaces for buses and trucks
Bedřich, Marek ; Čepil, Jiří (referee) ; Radimský, Michal (advisor)
Main focus of diploma thesis is optimalization of dimensions stated in parking norm ČSN 73 6056 Parking areas for road vehicles. Goal of the thesis was to optimalize dimensions stated in norm from 2011, eventually come up with a new type of parking space. Thesis is based on recherche, which was done on both previous and actual Czech norms as well as on foreign norms. Change in dimension was possible due to evaluation of swept paths of the individual parking slots. New suggested dimensions are stated in the conclusion.

Optimalization of design elements in ČSN 73 6056
Závadská, Andrea ; Jakl, Tomáš (referee) ; Radimský, Michal (advisor)
Diploma thesis in general is about the basic standard for designing parking places, which is ČSN 73 6056 Parking areas for road vehicles. The aim of thesis was to find parameters to be updated since last version of standard in 2011. The basic step to reach this goal is detailed study of current standard, the standard before 2011 and other European standards. Parameters to upgrade could be size of design vehicle and some types of parking spaces. All results of analysis used for finding parameters to be changed are engaged in annexes of thesis.

Analysis of Municipal Solid Waste Composition
Novák, Michal ; Kropáč, Jiří (referee) ; Šomplák, Radovan (advisor)
This diploma thesis provides extensive research of municipal solid waste studies and methodologies from all over the world. Firstly, the studies are described in general and then divided into several groups depending on the principle of their working practices, including their advantages and disadvantages. Secondly, the studies are divided by geographic areas. The results of the individual studies are presented and compared. Based on the findings in the thesis, appropriate methodology for municipal solid waste analysis in the Czech Republic is proposed.
