Study of alternative ending of nuclear fuel cycle in the Czech Republic
Michalica, Jaroslav ; Radil, Lukáš (referee) ; Šťastný, Ondřej (advisor)
This bachelor thesis deals with the alternative end of the nuclear fuel cycle in the Czech Republic. At the beginning of the work, the nuclear fuel cycle is explained, then the radioactive waste, how it is produced, and how we divide it. This is followed by a chapter that deals with the removal of the used nuclear fuel, from its extraction from the reactor through its temporary storage until its final disposal in an underground waste repository. The work then explains the alternative of direct disposal of used nuclear fuel, namely reprocessing of used nuclear fuel. It explains the existing methods for the reprocessing of used nuclear fuel which are currently being used, and where the used nuclear fuel reprocessing plants are located. The conclusion of the thesis deals with the economic comparison of direct final disposal of used nuclear fuel with reprocessing and final disposal of radioactive waste.

Determination of nuclear reactions' microscopic cross-sections using an accelerator-driven neutron source
Filová, Vendula ; Šťastný, Ondřej (referee) ; Král, Dušan (advisor)
Tato práce se věnuje určení mikroskopických účinných průřezů interakcí neutronů s indiem. Teoretická část shrnuje neutronové zdroje používané ve vědě i průmyslu, popisuje princip jejich fungování a představuje příklady jejich aplikací. Praktická část obsahuje postup vyhodnocování velikostí účinných průřezů včetně jednotlivých provedených korekcí. Byly vyhodnocována data celkem ze tří experimentů, při kterých byly produkovány neutrony interakcí protonů s tenkým lithiovým terčem. Kvazi monoenergetickým neutronům byly vystaveny sendviče folií včetně foile z india, produkty interakcí byly měřeny pomocí gamma spektrometrie. Výsledné mikroskopické účinné průřezy jsou porovnány s daty z knihoven evaluovaných dat a z knihovny EXFOR.

Freedom of speech, its guarantees and limits in the context of Czech media
Šťastný, Ondřej ; Hofmannová, Helena (advisor) ; Gronský, Ján (referee)
(K práci pouze volně přikládám, protože abstrakt není vyžadován platným zněním Rigorózního řádu Právnické fakulty Univerzity Karlovy). Mgr. Ondřej Šťastný Rigorózní práce se zabývá vybranými aspekty svobody projevu tak, jak je vymezena v našem právním řádu a v právu mezinárodním a evropském. Zvláštní pozornost věnuje limitům svobody projevu a střetům tohoto politického práva s jinými základními právy. Významná část práce je věnována detailnímu rozboru zásadních judikátů, které v posledním desetiletí formovaly podobu a meze svobody projevu v České republice. Konkrétně jde o vesměs hojně veřejně diskutované kauzy, ve kterých figurovala média. Jsem přesvědčený, že je to právě konkrétní soudcovské dotváření práva, kde lze vysledovat mnoho inspirativních právně-filosofických názorů na to, jak má svoboda projevu v naší (stále ještě mladé) demokracii vypadat. Abstract This work deals with the selected aspects of the freedom of speech as it is guaranteed in Czech, International as well as European law. Special focus is put on the limits of the freedom of speech and its conflicts with other basic freedoms. Important part of the work is dedicated to the core cases, whit traced the shape of the freedom of speech in the Czech Republic in the 2000s. For the most part, these are the frequently discussed cases...

The effectiveness of offensive game going on in phases depending on the leight of their duration (on the example of elite basketball team)
Šťastný, Ondřej ; Velenský, Michael (advisor) ; Kaprálek, Tomáš (referee)
Title: The effectiveness of offensive game going on in phases depending on the leight of their duration (on the example of elite basketball team). The target is to learn and review the game offensive efficiency of the best world basketball teams depending on the game offensive phase duration. I am going to focus on the national US basketball team during the last parts of the World Championship FIBA 2010 in Turkey and 2014 in Spain, concretely 1/8 final, quarterfinal, semi-final and final, where I can count with the maximal try to win. The method is to learn, analyze and evidence of the chosen game play effects. I am able to analyze every game offensive phase by the way of game record and to evaluate which phase is the most effective depending on its duration. The target is to review the game offensive efficiency of the best world basketball teams (US national team) depending on the game offensive phase duration. The work should be benefit for basketball coaches in their basketball players' trainings. The main importance is to set the players' game activities which guide the team performance in its offensive phase and get to successful score. The main method is to collect the data from the video records of the single World Championship games. The following analyze and evidence of the studied effects...

New Trends in Ionizing Radiation Shielding Research and Development
Vláčil, Martin ; Šťastný, Ondřej (referee) ; Katovský, Karel (advisor)
This thesis deals with the problem of shielding ionizing radiation which is a beam that has enough energy to ionize an atom or a molecule of an irradiated substance. This radiation can occur in nuclear facilities such as a nuclear power plant, a particle accelerator, or in X-rays in healthcare. Until now, standard shielding materials, most often lead or concrete, have been used to protect against ionizing radiation. New trends are therefore trying to replace these materials with lighter, more effective and harmless materials. The practical part is focused on measure the data to obtain the basic properties of shielding materials, such as the attenuation factor and the buildup factor. A measuring platform is described here, which can be used to measure the data needed to calculate the attenuation factor and the buildup factor. The measurement results are compared with tabular values to determine the accuracy of the measurements. Furthermore, the results of measurements of five concrete materials from the company MICo, spol. s r.o. To obtain theoretical values, the simulation program MCNP6 was used, in which it is possible to create a model of the measuring platform, which was used in practical measurements. Next the shielding material, source and detector are defined. The result lead again to the data needed to determine the attenuation factor. The results of measurement and simulation data in MCNP6 are evaluated and graphically processed into such a form that it is possible to compare the properties of shielding materials with each other.
