Thermal degradation of alternative electrical insulating liquids
Vodička, Tomáš ; Kazelle, Jiří (referee) ; Frk, Martin (advisor)
This thesis deals with alternative thermal degradation of electrical insulating liquids. The theoretical part describes the current state of the problem, electrical insulating liquids, their classification and types. There are described properties of electrical insulating liquids, their models of aging and diagnostic methods in accordance with the appropriate standards. In the practical part are chosen by representatives of alternative electrical insulating liquids and there are determined their dielectric characteristics in the initial state. According to the measured values is chosen five candidates for which it is designed and implemented an accelerated degradation test. During the test are measured dielectric parameters of the selected oils. Measured dependencies are mathematically approximated. In conclusion, the results are compared and physically interpreted in view of oxidation stability.

Antistatistic properties of materials in engineering practice
Vodička, Tomáš ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The bachelor thesis deals with the properties of antistatic materials in engineering practice. The theoretical part described mathematically and physically electric field, the principle of electrification, triboelectric effect, types of electrostatic discharges, types of antitatic materials and methods of measurement surface and volume resistivity. In the practical part is designed the automated measuring workplace with electrometer Keithley 6517 and with the test chamber Keithley 8009, creating an application in Agilent VEE Pro, measurement of surface and volume resistivity on commercial materials and materials with various surface finishes, realized by cathode sputtering and the inclusion of materials in each group.

Proposal of Knowledge Management System
Novohradský, Marek ; Vodička, Tomáš (referee) ; Koráb, Vojtěch (advisor)
This master’s thesis deals about Knowledge management in a small organization, and identification of knowledge resources and needs and the integration of knowledge management principles into the daily work of the organization. The theoretical part explains the basic terms and assumptions of knowledge management and shows a multidisciplinary overlap of knowledge management. The practical part deals with analysis of current situation of organization, especially in terms of utilization of knowledge resources and their evaluation, and design an appropriate system for managing knowledge in the organization.

Optimizing the design of the workshop belt grinder
Vodička, Tomáš ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
This thesis deals with optimalization of already existing design of belt grinder on basis of trial operation and design based on optimalization. In the research part are mentioned basics of grinding and categorization of belt grinders. In next part, the reader is introduced to existing design. Following by analysis of flaws and part about optimalization, where flaws are resolved, and new optimised design is checked by engineering calculations.

Speed Abilities of Athletes 10 - 14 year old
Vodička, Tomáš ; Vindušková, Jitka (advisor) ; Kaplan, Aleš (referee)
Title: Speed abilities of 10 - 14 year old athletes Aims: The aim of the work is to assess the speed abilities of selected children from athletics categories U12 and U14. We are mainly interested in the percentage improvement of the monitored group of athletes as a whole, individual categories and individual athletes. We also determine the size of the relation of individual outputs (correlation). Methods: We uses the method of analysis and comparison to obtain the results. The tests were selected and adapted to test the speed and strength abilities of the athletes. For our purposes, we chose 3 tests (50m PVS, long jump from the place, optojump SQJ and CMJ). Each athlete participated in at least 5 testing during 1.6 - 1.7 years. Results: Most athletes improved their performance during the testing period. We found the tightness of the relation between individual test performances and somatic values. The tightness of the relation between the performance in the 50m PVS test and the long jump from the site was found to be tight with the tightness of the relation between the performances in the 50m PVS test and the performances in the SQJ / CMJ optojump tests. For testing speed-strength performances for categories up to 14 years is suffice 50m PVS test and a long jump from the spot. The SQJ and CMJ...

Comparision and characterization of Korean martial arts Taekwon-di ITF and Taekwondo WTF
Vodička, Tomáš ; Pavelka, Radim (advisor) ; Stich, Jaroslav (referee)
Title: Comparison and characterization of Korean martial arts Taekwon-do ITF and Taekwondo WTF Objectives: In this work will be examined charakteristic of sport disciplines, philosophy, success in competitions of czech competitiors Methods: For the development of this theses was used a method of gathering information of these two federations of Czech and foreign literature. Results: It was found that Taekwon-do ITF is a martial art, which consists five sport's disciplines and our representatives from year 2000 at european championships won 237 and at world championships won 61 medals. WTF Taekwondo is a combat sport and the main discipline is Kyorugi (sparring). Kyorugi is the Olympics. Our representatives in WTF Taekwondo from year 2000 won only 5 medals at european champinships. Keywords: Korean martial art, International Taekwon-do Federation, World Taekwondo Federation

History and development of Tae Kwon Do
Vodička, Tomáš ; Pavelka, Radim (advisor) ; Venzara, Jan (referee)
Title: History and develompment of Tae Kwon Do. Objectives: This work investigated the origins and develompment of Tae Kwon Do. The federations are International Taekwon-do Federation and World Taekwondo Federation. Methods: For preparation of this work I have used as a method of gathering knowledge about these two federations of Czech and foreign literature. Results: It was found that original Tae Kwon Do was founded in 1955 in Korea. The International Taekwon-do Federation (ITF) was established in 1966 and in 1973 was established the World Taekwondo Federation (WTF). In this work it was found that apart form the name and the country are two different martial arts. ITF is a tradition martial art of self-defense, founded by General Choi Hong Hi. WTF is rather a combat sport, which is part of the Olympic sports. Keywords: korean martial art, International Taekwon-do Federation, World Taekwondo Federation, history of Tae Kwon Do.
