Ice hockey in physics tuition
Adámek, Libor ; Drozd, Zdeněk (advisor) ; Kácovský, Petr (referee)
1 This thesis is connection between physics and well known sport, ice hockey. It also contains findings and examples, which can be used in physics teaching in primary and secondary schools. The thesis gathers several theories, that describe why is ice slippery on its surface and tries to point out and comment a long term misconception of pressure melting and gives arguments to disprove it aswell. Another part contains hockey game situations, serving as great practical examples of physics and aims to bring them to physics lessons, because of their attractiveness for sudents.

Modeling of meteorite impact
Takáč, Marian ; Kletetschka, Günther (advisor) ; Kohout, Tomáš (referee)
In Febuary 2013, in spectacular light and sound accompaintmen a meteorite hit the Russian Federation. Small fragment which landed in populated areas caused together with blust wave damage. The largest part broke the ice crust on the lake in outskirts of Chebarkul. The circular shaped hole gave rise to various conspiracy theories. About half of the year after impact the meteorite was lifted and conspiracy theories boken. The event immediately raised interest in the issue of the impacts of meteorites and phenomena associated with them. Processes when the meteor is passing trough atmosphere, impact craters, their origin and characteristics, computer models, types of meteorites and their origin. Or just a mystery of the hole in the ice crust of the lake Chebarkul. Science has got answers for such toppics. This paper is just trying to summarize them.

Actions on bridges caused by the water flow and floating items
Řezník, Jindřich ; Duchan, David (referee) ; Špano, Miroslav (advisor)
The subject of this thesis is the enumeration and analysis methods applicable to the calculation of loads on bridges from water and water-borne objects. It involves a hydrodynamics loads, loads from captured debris and from impacts of the individual water-borne objects and their clusters. It includes an assessment of the current situation, the teoretical analysis and model calculations on the concrete bridge with the evaluation of usable methods.

Aircraft de-icing systems
Smékal, Aleš ; Bencalík, Karol (referee) ; Třetina, Karel (advisor)
The bachelor´s thesis is familiarization of me with icing on aircrafts. It includes the distribution systems for anti-icing and de-icing, energy intensity and efficiency are also included. It contains icing situations, which are very dangerous for aircrafts. Thesis shows possibilities, how to prevent ice formation, detect icing and keep pilot informed. And finally remove ice.

Contaminated Runway Operations
Michna, Tomáš ; Hammer, Jaromír (referee) ; Šošovička, Róbert (advisor)
This bachelor thesis solves problem of operation from contaminated runway. It lists individual kind of contaminant and describes measuring, which is doing on contaminated runway. It also deals with devices for measuring friction coefficient runway surfaces. There are also the methods, which publishing informations about state of runway. At the conclusion compares the limits that are affected by contaminated runway.

WebSocket and AJAX effectiveness comparison through collaborative editor implementation
Augustín, Jakub ; Zamazal, Ondřej (advisor) ; Vojíř, Stanislav (referee)
This thesis introduces modern web technology WebSocket that was designed to improve real-time communication. Websocket usage is described from both, server and client sides. This thesis should point out benefits of using WebSocket through the collaborative editor implementation. Application ICE, that is practical part of this thesis, shows real-world WebSocket implementation. Also, this thesis lists some of the most widely used techniques for real-time communication. AJAX is currently the most common of these techniques. This thesis should compare WebSocket to AJAX as the competitive technology. Apart from theoretical comparison, this thesis should also provide a real-world testing and comparison.

The proposal and verification of a water rescue training program for fire brigade units
KOCINOVÁ, Monika
The thesis, which is divided into a practical and a theoretical part, examines the level of knowledge among the members of the Fire Brigade of the South Bohemia region. The theoretical part characterizes the Fire Brigade of the Czech Republic, its mission and tasks, its position within the Integrated Emergency System. The theoretical part deals with the issues of stagnant, flowing and frozen water hydrology, physiology related to staying in cold water and the possibilities to use rescue and protective aids. I also present a list of dangerous situations rescuers are exposed to when rescuing on water surfaces. Results of a questionnaire research are processed and evaluated in the practical part. The questionnaire deals with the issues of stagnant, flowing and frozen water hydrology, the basic theoretical knowledge as well as practical skills of the members of the South Bohemian Fire Brigade. The most important findings resulting from the performed research are summarized in the conclusion of the work. I evaluate the aims and hypotheses set at the beginning and propose a possible solution of the problems in question.

The use of AJAX technique in interactive collaborative editor
Augustín, Jakub ; Kosek, Jiří (advisor) ; Šmejkal, Ivo (referee)
Bachelors thesis gives notice about incapability of today`s CMS systems to deal with simultaneous editing of text content by more users at the same time. By its beginning, thesis is analyzing the problem in depth and seeks its substance. The thesis is not devoted to the problem analysis only it presents the solution too. The solution in this case is collaborative editor. Thesis studies possibilities of its creation and is searching for technologies and techniques that would make it easier. Theoretical part of this thesis explains currently widely popular technique AJAX and benefits it brings that enable existence of collaborative editor as a web application. The thesis defines basic rules that must be followed while creating such an editor. Internal structure and functionality of the application is described by UML diagrams. Practical part of this thesis is the application itself.
