Design of overvoltage arresters in high voltage switchgear depending up parameters of connected load
Němec, Ondřej ; Bernard, Michal (referee) ; Lázničková, Ilona (advisor)
The purpose of this thesis is to introduce the reader about the problems of design of surge arresters. The first part of this thesis describes problems of surge. In the next part of this thesis are described test pulses needed to test surge arresters. The next issues of this thesis are medium voltage switchgears and surge arresters ABB and their test. In the next part ot this thesis are described type of network according earthing of transformers. The other point of this thesis are aplications of surge arresters, figures and calculation for networks, generators, transformers and motors. In the conclusion of this thesis is the appreciation of whole problems about surge arresters.

Selection and Application of Surge Arresters for Middle-Voltage Air-Insulated Switchgears
Němec, Ondřej ; Bernard, Michal (referee) ; Drápela, Jiří (advisor)
The purpose of this thesis is to introduce readers with design of a surge arresters in four different categories. In the first part of this thesis is described theory of overvoltage, surge arresters and testing. The second part of this thesis is focused on design of surge arresters to protect from overvoltage due switching capacitive loads. The thesis continued with design of surge arresters in medium voltage network. The next part is design of surge arresters to protect from overvoltage due switching inductive loads. The next point is protective distance of surge arresters in different lighting overvoltages. In the conclusion of this thesis is the appreciation of whole problems about surge arresters.

Analysis of production process completeness of switchgears
Stokláska, Jiří ; Bernard,, Michal (referee) ; Paar, Martin (advisor)
This thesis introduces company ABB Brno and its products. It describes the manufacturing process of a switchgear and it is focused at working procedures at particular points of the assembly line. The main part analyzes the root causes of the incompleteness of switchgears in the relation to the components availability. Time footprint was worked out. As a conclusion the proposal of changes in manufacturing process to improve the level of completeness are stated.

Vratislav Effenberger's view of film
Strejcovský, Jan ; BREGANT, Michal (advisor) ; BERNARD, Jan (referee)
This thesis deals with a diverse relationship of Vratislav Effenberger to film. It describes the role, which he played in shaping the czechoslovakian postwar surrealism. On his only realized film "Study on the fraction of reality", this work demonstrates concrete methods, that he found substantial for the cinema.It follows his engagement in Czechoslovak film institute and analyzes his pseudo-film scripts issued in a book "Cynicism of life and brutality of reality". The aim of this thesis is to outline Effenberger's passion for film as a significant part of inexhaustible legacy of this yet unappreciated poet, art theorist, historian, screenwriter and the most important writer of Czech post-war surrealist generation.

Aspects of free movement of persons in Community law
Schneiderová, Petra ; Bernard, Radovan (advisor) ; Spirit, Michal (referee)
Táto diplomová práca sa zaoberá právnou úpravou voľného pohybu osôb v komunitárnom práve, jej vývojom a súčasným stavom. Konkrétne sa zameriava najmä na zmeny v právnej úprave, ktoré nastali po prijatí smernice 2004/38/ES, ktorá zrušila predchádzajúce smernice upravujúce túto oblasť. Práca sa zaoberá prínosmi tejto smernice v oblasti slobody pohybu, ktoré spočívajú najmä v zjednodušení úpravy a rozšírení oprávnených subjektov. Rozbor smernice sa zameriava na práva plynúce z voľného pohybu a na možné obmedzenia tejto slobody. Práca porovnáva aj českú právnu úpravu, ktorá smernicu implementovala a jej súlad s požiadavkami smernice.
