Alternative sources of nuclear energy
Svoboda, Josef ; Zlámal, Ondřej (referee) ; Katovský, Karel (advisor)
In places where it is not possible to use conventional production and distribution of energy, autonomous sources take over. Most of autonomous sources use solar energy, wind energy and other renewable resources. For applications such as special missions into outer space the usage of conventional sources is not possible. Except for powering special satellites, unconventional nuclear sources are also used in autonomous unmanned objects located in distanced areas with extreme natural conditions. It is also used in unusual propulsions of ground, water and air machine. These vehicles are for example pacemaker powered by radioisotope source, submarines, aircrafts and other vehicles supplied by nuclear reactor of unconventional conception. In this bachelor thesis there are globally summarized questions connected with unconventional sources of nuclear energy with detailed description of chosen parts. This work is concerned with finding more efficient machinery for conversion of heat energy supplied by radioisotope decay to electric energy.

Sensorless velocity control and positions of d.c. low-power brush motor
Svoboda, Jan ; Hanák, Pavel (referee) ; Prajzner, Václav (advisor)
This bachelor's thesis focuses on sensorless control of low load brushed DC motor that is used in the actuators made by the Honeywell company. The first part provides an introduction into motor control and common used methods of speed and position sensing of brushed DC motor. Sensorless method of sensing described in this work is the detection of commutation pulses from the signal of motor current. These pulses are caused by brushes leaping over the commutator bars. Correct evaluation of commutation pulses can provide the information about velocity and position of the motor. This relatively new method of detection of commutation pulses is investigated and arising problems are demonstrated on measured samples of signal. Suitable methods of signal processing are then proposed. Infallibility of these signal processing methods is then proved on the set of signals measured under circumstances of supply voltage and abrasion. Then it is decided which signal processing method that sensorless control system can use is the best.

Timelessness
Svoboda, Jonáš ; Turek, Filip (referee) ; Cenek, Filip (advisor)
Calm film tries to be a kind of portrait of a young free life in the city. Freedom, upachtěnosti. It's a portrait of notes from phone, lemonade flavored with emptiness. Humbly evaporate. Passionate amateurism, because the toilet are not alone, there is with thee Wittgenstein. The fact that we saw a squirrel as a mouse eats. The fact that when we go to town, so we are pretty huge. The fact that it all actually means something. "Vynuděnej klidňák" Lord hate emotions and Jagr afloat bet. The fact that I have one whole night inhaled Pizza Hawaii, which became Pizza Pearl Harbour because I fell asleep. The fact that it is good then the rest of charcoal dance. About how he met at kávomatu dudes, gunk and artificial intelligence to agreed that hate and love must prevail over truth and falsehood. Instead, after a quill on the bottom of the crucible DNA they found God. Then came the doorman and said that the school is non-smoking. And then there is the moment when we lack love, peace, and we have a long time we were visiting. The fact that we were in rehab and has since everyone involved. The fact that Tomas přidělal the old wheel chair and wrote on it "ZEUS". Contemplation of revolting tag Elektro Planeo on the wall. Because staring contest with the camera is a job like any other. The fact that my vegetables says I'm outside because he hates anyone who is interesting. A tag is an interesting question - "is not a vegetable shit?" Humor in the joy of grief. Because I have sympathy with the man who has read this. Something is simply in a poem trapped and can not get out. The method of the Hitler-Stalin-Picasso, the smell and pain, emptiness and dullness, sabotage and nervousness, contactless man, colorful variety of residues of superpowers in said "yes" and the superhero resistant to alcohol. Nuclear metaphysics in a world where the Lord God far and high. In the role of a collector's Bizarre man playing Lord dimes with the task to deliver power to the last ten-kávomatu fate. The Old Man and the wine, which put on a fag and he will tell you that genius is hiding at the bottom, vigilance and misunderstanding diletující memory and increasingly sadder smile. Nasty weather and the feeling that "next door is fucking nations" - (Paul Ondračka - The celebration of music and poetry). Method free stream of consciousness portrayed as a method of glaciers. The fact that the last time I lost my laptop when I tried if underwater works wifi. Dementia and escape from evil - as far as possible. Trying to focus, at least for a while. Since I was working basically a documentary (- the film's treatment of captured video archives), the choice of media video-essays, hence the film entirely clear. The illustrated try to look out of their personal, participant of view, but also with a "judgmental - documentary apart." I inspiration for creating Calm sought mainly in the work of Werner Herzog, Karel Vachek and their relation to the relativity of truth and nature. Compared with its previous results, which were more experimental in nature evaluate his work as a targeted and focused. The aim of the work is a portrait of the place, time and people. He has absolutely no practical benefit, except perhaps enrich the viewer's soul and portrait modes.

Jiří Voženílek v poválečném Zlíně
Svoboda, Jiří
Po Druhé světové válce dochází v celé Evropě k mnoha změnám v důsledku přerozdělení zájmů tehdejších velmocí. Československo prochází společenskou a ekonomickou konverzí. Mnoho velkých továren bylo zestátněno, mezi nimi i továrna na výrobu obuvi „T. a A. Baťa“, pod novým názvem „ Baťa, národní podnik “. Vzhledem k této zásadní změně postupně dochází ke změnám v sociální politice továrny, které výrazně předjímají další politický, ekonomický a sociální vývoj v naší zemi. Nejradikálnější změny se odrážejí ve způsobu bydlení a urbanistických koncepcích. Zatímco doposud žili zaměstnanci továrny odděleně a podle zařazení v továrně v odpovídajícím komfortu, nyní začínají převládat tendence společného bydlení. Generace architektů, která přišla do Zlína ve třicátých letech, se začíná prosazovat novými názory a společenskými postoji. Architekt Vladimír Kubečka vytváří urbanistický návrh nové čtvrti – „Čtvrti Julia Fučíka“ při východním okraji Zlína. Autorem zdejších tříetážových domů je architekt Vladimír Karfík. Svým pojetím bydlení jsou domy dodnes aktuální. Architekt Miroslav Drofa staví podél východní osy směrem k centru „Věžové domy“ podle švédských tendencí a následně s využitím původního zlínského skeletu „Morýsovy domy“, tehdy nazvané „8 etážové činžovní domy ve Zlíně“. Dochází však ke změnám v klasické zlínské konstrukci a původních 6,15m x 6,15m je vývojově nahrazeno u těchto dvou domů trojtraktem 6,8m+2,6m+6,8m x 6,8m.

Architektonické a technické prostředky tvorby elektroiontového mikroklimatu budov
Svoboda, Jiří
Mikroklima budovy je nezbytnou podmínkou k tomu, aby stavba splnila účel, pro který byla navržena. Škála požadavků na vnitřní mikroklima je tak široká, jak široká je škála způsobů užívání. A stejně široké jsou i možnosti architektů a inženýrů při hledání cest k zajištění co nejlepšího prostředí v budovách. Cílem článku je vymezení oblasti problematiky mikroklimatu budov, která bude řešena v disertační práci na téma Reálnost tvorby mikroklimatu budov architektonickými a technickými prostředky.
