Surface relief evolution in cast superalloy In738LC fatigued at room temperature
Samek, Petr ; Obrtlík, Karel (referee) ; Juliš, Martin (advisor)
Low cycle fatigue is an important valving parameter of materiale which are exposed random alternate strain during their operation. The alternate strain in that material is caused by temperature fluctuations during operation and outages such as aircraft engines. Tests of low cycle fatigue were performed on samples of superalloy Inconel 738LC at stable room temperature at 23°C. The actual experiment took place at certain intervals, consisting of cycling itself, and observing changes in surface relief by light and electron microscopy. There was observed significant surface relief at an early stage of low cycle fatigue. We compared results of measurement with other different observation methods.

The measurement of the velocity of abrasive particles at the suction part of the cutting head
Foldyna, Josef ; Zeleňák, Michal ; Klich, Jiří ; Hlaváček, Petr ; Sitek, Libor
To be able to optimize the design of the abrasive cutting head using numerical simulation, it is necessary to gather as much information about processes occurring in the cutting head as possible. The development of the numerical model of processes occurring in the abrasive water jet cutting head during the process of creation and forming of abrasive water jet is currently in progress at the Institute of Geonics in Ostrava. The verification of the model requires, among others, to determine the behaviour of abrasive particles at the input of the cutting head. Therefore, the visualisation of abrasive particles at the input using various parameters of abrasive jet and its subsequent analysis was performed using shadowgraphy (backlighting) technique and the results are presented in the paper.

Theoretical considerations on the liability of a sportsman in the Czech legal system (liability of a sportsman in collective sports)
Vondráčková, Liběna ; Beran, Karel (advisor) ; Hřebejk, Jiří (referee)
Závěrem lze konstatovat, že vytvořit všemi přijatelnou obecnou definici sportu, resp. sportovce, je úkol, který se zatím nikomu nepodařilo úspěšně vyřešit. Existence takové definice má svůj nesporný význam už jen proto, že chceme-li se zabývat "právní odpovědností sportovce", je třeba nejprve vymezit okruh osob, jichž především se předestřené úvahy týkají. Skrze historický vývoj jsem se v kapitole druhé pokusila naznačit rozsah sportovní činnosti, která je z hlediska požadavku jednotné obecné definice díky svému fenomenálnímu rozměru velice těžko uchopitelná. K významu této definice se pak znovu vracím v kapitole čtvrté v rámci vymezení subjektu odpovědnostních vztahů. Mnou zvolená definice je jistě jen jedna z mnoha možných a neklade si nárok na její bezvýhradné přijetí. Kapitola třetí je věnována exkurzi do historie, kde se vracím až na samotný počátek evropské civilizace, tj. do období antických Řeků a Římanů. Platí-li to pro práci jako celek, tak pro tuto kapitolu dvojnásob, totiž že s ohledem na limitovaný rozsah nemůže obsáhnout zkoumanou látku komplexně. Vedle zajímavého odkazu středověku v oblasti hodnocení sportovních úrazů je tedy věnována pozornost toliko pouze Antice. Nikoli však neprávem, neboť zde můžeme nalézt velmi inspirativní a obdivuhodně nadčasové myšlenky použitelné i ve 21. století....

The Model of Financial Compensation for placement of a Deep Geological Repository of Radioactive Waste in the Czech republic in period from 2010 to 2016
Englerová, Anna ; Zeman, Martin (advisor) ; Vebrová, Ludmila (referee)
Author examines a way of allocation of governmental financial resources to municipalities in locations preselected for deep geological repository. She is searching for a way how to add a motivational incentive to the process of allocation of financial resources in order to improve municipalities attitude towards deep geological repository. Hypothesis, examined in this thesis, contains two related questions. It is assumed that (1) amount and structure of financial resources can significantly affect municipalities decision making and also that (2) current mechanism of allocation of compensations is ineffective and does not create sufficient incentives. Currently (end of the year 2016), negotiations between government and municipalities are in crisis despite significant financial compensation from government nuclear account to the municipalities. This thesis have potential to change municipalities negative stance on deep geological repository through motivational model of resource allocation. Theoretical part reviews basic economic background and introduces historical, sociological, technological and economic views of radioactivity and deep geological repository. In practical part author analyzes socio-economic situation, compares evolution of transfers from government to municipalities with their attitude towards deep geological repository in time and shows that current system of resource allocation does not motivate the municipalities to change their stance on deep geological repository. That confirms second part of our hypothesis. Author also proposes a motivational model of resource alllocation. She confirms its viability by comparing it with similar models from other countries, by surveying mayors of concerned municipalities and also by examining experts opinion. Verification of the model confirmed its motivational effect. By that, first assumption of our hypothesis, that structure of resource allocation can significantly affect municipalities decision making, was confirmed.

Progress of the system of public health insurance and health insurance companies in the Czech Republic for the period 2000 - 2015
Pecková, Tereza ; Lukášová, Tereza (advisor) ; Bartůsková, Lucia (referee)
This bachelor´s thesis analyzes the basic funds of health insurance companies for the period 2000 - 2015 in the Czech Republic, especially the creation of resources and their use and the entire system of public health insurance in the Czech Republic. Basic funds are one of the components of the overall economy of health insurance companies. First it is necessary to describe the market of the insured. The insured create and use the finances within public health insurance. Also important are contributions from the state budget for those insured by the state. We can conclude that the cost of health insurance companies are rising and that population is aging in the Czech Republic. However, this is not a balanced linear growth. The number of pensioners grew at a slower rate of growth, but according to population development forecast, there should be faster growth in the number of pensioners in the following years. Significant growth in cost is particularly noticeable in the age category of 80 and above, and increasingly more people should live up to this blessed age, also thanks to modern public health.

New perspectives in distribution of Czech Documentary Films - digital distribution DCI and VOD platforms
Kinkalová, Barbora ; Rezková, Hana (advisor) ; Oukropec, Petr (referee)
This thesis examines new possibilities in film distribution from the point of view of documentary films. It occupies with the fact what could the coming system of digital distribution in the DCI standard and also the possibility of distributing the films by the means of video on demand (VoD) portals bring. The work is divided into two main circles.
The first part starts with a brief description of the progress of the theaters digitalisation till present days. Then it comes to the topic of actual functioning of digital DCI distribution and to the definite cases of documents, that were distributed this way in the first half of the 2010. It also speaks about the leading role of the Ministery of Culture of the Czech Republic and its Media and Audiovision Department. Further it describes the changes, which the new system brings, from the three main points of view ? from the perspective of theatres, distributors and producers. At the end this first part deals with new trends in marketing of documentary films, which is in a tight connection with coming digitalisation and the need of target marketing.
The second part of the thesis beginns with the description of the functioning of the VoD portals. It speaks about legislative system, the topic of territories, engaging the VoD servers to the distribution chain and the form of the support by the means of the EU programme MEDIA. In a detailed way, it examines than the work of eight definite foreign VoD portals, which specialize in showing the documents only, or together with other kinds of film. The Czech docalliancefilms.com is the last one from the described portals. At the conclusion, the thesis deals with the summary of the contemporary situation in the VoD portals field and hypothesis for the future. It tries to define the possible future trends in the progress of this way of distribution.

The Study of Systém and Process optimization of Service operation
Prokeš, Viktor ; Havlásek, Roman (referee) ; Jurová, Marie (advisor)
This thesis is oriented on the automotive industry with the focus on the domestic producer of the vehicles – the Škoda Auto Company. It describes the subject of business in the mentioned company and subsequently it refers to the current trends of the automotive market in the Czech Republic. On the basis of the analyses` results of the after-sales services allied with usage of the Škoda-products it will propose their possible future progression. Thereinafter will the thesis concentrate on the description of the existing after-sales processes focused on the „through-pass“ of the vehicle through the authorised Škoda Auto service. It deals with the analysis of the service systems in detail using the tight cohesion of them. Modern technologies used in the current vehicles put significantly higher demands on their maintenance, which call for the continual optimization of the service processes with the maximal utilisation effort of the feedback. The appropriate personnel have become the necessity. For these purposes it will be recommended the introduction of the electronic multipurpose memory devices intended for the data collection. In the next step will the after-sale-service process be described with the focus on the usage of these electronic memory vehicle-keys with the reference to the procedural simplification of the maintenance operations. The final part of the thesis will evaluate the general contribution of the proposed resolution for the service processes as well as their users.
