Dimensioning of Earthing System in HV Switchgear
Buršík, Roman ; Matuška, Marcel (referee) ; Orságová, Jaroslava (advisor)
My master's thesis is focused on grounding of HV switchgear. The aim of this work is to create a computer program intended for dimensioning of earthing networks. The earthing networks are the most convenient alternative in term of effective grounding and distribution of ponential. They are based on latiny a flat conductor network cables and connection of appliance parts to network. Introduction of the thesis is dedicated to explanation of grounding theory and to description of requirements essential for properly designed earthing system (dimensioning of earthing system). Following chapter brings description of computer program algorithm testing propriety of an assigned earthing network for a particular switchgear. The chapter also contains description of an user interface and explanation of all features, included in the program. Last part provides presentation of program utilization to particular numerical assignment.

Dance with a Million Knots. A return to craft techniques and artistic work with textiles in the context of contemporary artistic practice
Gryboś, Julia ; Klodová, Lenka (referee) ; Janečková,, Zuzana (referee) ; Rathouský, Luděk (advisor)
Dissertation entitled Dance with a Million Knots. A return to craft techniques and artistic work with textiles in the context of contemporary artistic practice maps the tendency of the return to craft techniques and handwork in the field of contemporary art. The tendency is reflected in the text through the definition of its relevant terms, examples of several domestic and international exhibition projects, the handwork-oriented practice of contemporary artists, and through a reflection on my own artistic practice. Following the assumption that the process of production and creation itself is now more central to artistic concerns, the dissertation asks for the causes and reasons for this turn, while also anchoring it in a broader social context. The reflection on the topic is presented in the thesis through an experience formulated from the position of a long-standing collaborative artistic practice with Barbora Zentkova, offering an associative reflection on the form and scope of the tendency in contemporary art, as well as on its possible sources and causes.

Sokolová, Petra ; Jindra, Matouš (advisor) ; Turek, Michael (referee)
Title: Set of training exercises for telemark skiing Objectives: The aim of the bachelor thesis is to create a complex that will inspire and contain various types of exercises, according to which each person can learn telemark skiing. Methods: From the methodological point of view of the bachelor thesis was used comparison of telemark literature, data collection and analysis, literature search. Results: The types of exercises that form the complex that each beginner can learn telemark skiing have been described and documented. The exercises were analyzed and based on the literature. Keywords: telemark, exercises, grounding, turn

Modelling Of Electrical Installations
Earthing Systems In Ansoft Maxwell
Vycital, Vaclav
This paper discusses the possibilities of modelling of ES in Ansoft Maxwell software. The possible way of definition of the problem with possible modelling difficulties were discussed. The possible error in obtained results by choosing a value of radius of the earth model as well as choosing a value of target percent error in the software by the user is also discussed. The discussion is supplemented with a simplified sensitivity analysis of these input variables and the results are validated by comparing the results with results obtained from simplified analytical formulas.

Health Education and Strategy of Mental Hygiene in Education Process.
KORCOVÁ, Petra
In my Bachelor Thesis I am dealing with a subject and form of mental hygiene education designed for secondary school students. This broad subject matter is introduced as a part of a healthy lifestyle and health education study prgramme. The theoretical part is focusing on collecting literary sources relating to this topic and describing Czech school background. The practical part contains applied methods as well as life rhythm and sleeping habits information of investigated group of students. Further we can find their needs and wishes. Thesis is resulting in guidelines for teachers and students which shall help not only to broaden mental hygiene knowledge but offer some practical skills to support the worth value of health and healthy life style.
