Černý, Marian ; Baláš, Marek (referee) ; Šen, Hugo (advisor)
Subject of this thesis is design of the steam generator for modular reactor. The dissertation consist of the theoretical part, where are described heat-exchangers and steam generators used in nuclear power plants. Second part contains theoretical calculations in the first approach (thermal, hydraulic and strenght calculation). In the next part are particular variants of steam generator selected. For the final variant are necessary calculations (introduced above) and drawings of selected parts are done. In the final statement is technical solution evaluated, and the parameters of the steam generator are compared with actually used steam generators.

Wheelchair control using EEG signal classification
Malý, Lukáš ; Sadovský, Petr (referee) ; Žalud, Luděk (advisor)
Tato diplomová práce představuje koncept elektrického invalidního vozíku ovládaného lidskou myslí. Tento koncept je určen pro osoby, které elektrický invalidní vozík nemohou ovládat klasickými způsoby, jakým je například joystick. V práci jsou popsány čtyři hlavní komponenty konceptu: elektroencefalograf, brain-computer interface (rozhraní mozek-počítač), systém sdílené kontroly a samotný elektrický invalidní vozík. V textu je představena použitá metodologie a výsledky provedených experimentů. V závěru jsou nastíněna doporučení pro budoucí vývoj.

Overview and Utilization of Small Modular Reactors
Křeček, Tomáš ; Števanka, Kamil (referee) ; Katovský, Karel (advisor)
This bachelor thesis deals with an auspicious type of new nuclear reactors – small modular reactors (SMR). It defines the basic qualities of SMR and their essential differences among large nuclear reactors, briefly evaluates the individual advantages and disadvantages. It summarizes the history and current direction of their development in the most active countries. In the bachelor's thesis are also discusses the most advanced propositions of SMR and the possibilities of their use. In the last part is analysis of the usability of SMR in the energy mixture and the possibilities of application in the Czechia.

Possibilities of using small modular reactors in the heating industry
Duchoň, Jan ; Šnajdárek, Ladislav (referee) ; Milčák, Pavel (advisor)
This bachelor thesis deals with nuclear energy, mainly focusing on small modular reactors and their possible use in heating industry. The first chapters are focused on history of nuclear energy, explaining key concepts and describing nuclear reactors and their principle in general. One of the crucial topics, covered in the following section are small modular reactors, key examples of SMRs, their wide range of uses and comparison of advantages and disadvantages of this type of reactors. Next chapter consists of introduction to heating industry, description of situation in Czech republic and analysis of Czech heating plants. The final chapter uses acquired information to assess potential use of SMRs in Czech heating industry as a replacement for fossil fuel heating plants.

The concept of the heat exchanger for the IMSR reactor
Števanka, Kamil ; Katovský, Karel (referee) ; Martinec, Jiří (advisor)
Cílem práce bylo vytvořit základní koncept integrovaného výměníku tepla pro solí chlazený reaktor vyvíjený společností Terrestrial Energy s využitím programu Promex. První kapitola se zabývá historií a současnou situací v oblasti výzkumu malých modulárních reaktorů chlazených fluoridovými solemi. Ve druhé kapitole jsou popsány vlastnosti fluoridových solí a konstrukčních materiálů. Poslední kapitola se zabývá simulací tepelného výměníku pomocí programu Promex, validací modelu, transformací protiproudého výměníku na výměník s U trubkami a vizualizací výměníku s použitím CAD Invetoru.

Immediate effect of posterior chain facilitation using foam rolling on reactive strength performance
Harasimová, Petra ; Hojka, Vladimír (advisor) ; Šťastný, Petr (referee)
Author: Bc. Petra Harasimová Thesis supervisor: Mgr. Vladimír Hojka, Ph.D. Expert consultant: PhDr. Jitka Malá, Ph.D. Mgr. Dominik Kolinger Title: Immediate effect of posterior chain facilitation using foam rolling on reactive strength performance. Objectives: The main aim of this study is to determine whether the inclination of the trunk towards the vertical changes after foam roller facilitation, whether the magnitude of the jump increases or whether the contact time during reactive force performance is reduced. Methods: In this thesis an experiment in the form of a randomized crossover study was used. Fifteen active female athletes with the problem of physiological maintenance of trunk position during running participated in the measurement. Subjects performed repeated snatch jumps over hurdles 57-68 cm in height. For the skip jumps, we measured jump height and support time using an Optojump (Microgate, Bolzano, Italy) and maximal trunk tilt using a video camera (GoPro HERO 9). After the warm-up, probands completed two measurements (pre-test) within 2 minutes. Then, the intervention group of probands performed foam rolling facilitation - m. triceps surae, mm. hamstrings, m. gluteus maximus, m. erector trunci; for each muscle group for 30 s, with a frequency of 1.5 Hz; the control group had rest...

Engineering geology conditions of a motorway bridge over Vltava river in Prague
Polák, Zdeněk ; Král, Jan (advisor) ; Havelka, Jaroslav (referee)
Tato diplomová práce se zabývá zhodnocením inženýrskogeologických poměrů mostu na stavbě č. 519 silničního okruhu kolem Prahy včetně vyšetření stability skalních svahů v místě předpokládané výstavby. Jedná se o přemostění hlubokého erozního údolí Vltavy, na jehož svazích vystupují na povrch horniny svrchnoproterozoického stáří. Na lokalitě byly zhodnoceny pomocí rešerše archivních podkladů, vlastní rekognoskace a laboratorních zkoušek, geologické, hydrogeologické a inženýrskogeologické poměry, které jsou přehledně uvedeny v inženýrskogeologické mapě v měřítku 1:2000 a řezu 1:500. Jako podklad pro vyhodnocení stability skalních svahů sloužila podrobná dokumentace skalních výchozů. Samotné vyšetření stability proběhlo pomocí klasifikace Slope Mass Ratting a Marklandova testu pro stereografickou projekci. Na výstupech práce je souhrnně popsán horninový masiv včetně mapy stability skalních svahů v měřítku 1:500 a popsány základové poměry uvažovaného mostu.

Warm up in ice hockey
Arnošt, Daniel ; Jebavý, Radim (advisor) ; Vojta, Zdeněk (referee)
Title: Warming up for ice hockey Objectives: The aim of these bachelor theses is to create a survey about warm up for ice hockey. Based on a survey, study of specialized literature and consultation with selected trainers I suggest a battery of exercises on a selected part of self-myofascial release with selected tools (foam rollers, balls). Methods: For the purpose of this bachelor thesis a quantitative scientific method was used. The data was obtained using the poll method. Data has been embedded in Excel. From these data, tables and charts were created. Results: Players spend longer time before the game than before training. Next results have confirmed that players have knowledge of mobilization, activation and self-myofascial release exercises. They use specific tools - foam rollers, resistance bands and balls. I create a battery of exercises for self-myofascial release. Keywords: ice hockey, warming up, foam roller, mobility, SMR
