Creep of intermetallic alloy TiAl at very low strain rates
Mareček, P. ; Kloc, Luboš ; Fiala, J.
Intermetallic alloys are very advanced materials for high-temperature applications. There are series of attractive properties exceed coventional up to now used creep resistance steels. The creep behaviour of TiAl alloy was investigated under an applied stress lower than 100 MPa at temperatures 700-850 °C. The strain rate was lower than 10-9 s-1 under testing conditions, which have importance for technical applications. In relation to results, the creep behavior of intermetallic alloy TiAl shows a transition to a mechanism with low stress exponent in the range of minimum strain rates, similar to creep resistance steels with evidence change of deformation mechanism under strain rate 10-10 s-1 . However, this transition in TiAl alloys is not as clear as in creep resistant steels.

Poupová, Jana ; Procházka, Pavel (advisor) ; Lukášová, Tereza (referee)
This bachelor thesis analyses the system of tertiary education in the Czech Republic, especially the way of funding of this system and the reform of the system of funding, implementation of tuition-fees on public universities. This topic had been actual until year 2015 and it is highly probable that it becomes more actual in following years again. In the teoretical part of the thesis, there are described in details the system of tertiary education in the Czech republic, the process and main points off the reform of tertiary education and there is also briefly described the system of tertiary education in Great Britain. The practical part of the thesis verifies by questionnaire survey the possibility of implementation of tuition-fees on universities and examines the impatcs of this implementation. In case of implementation of tuition-fees, as it was planned according to the reform of tertiary education, the number of university students would decrease by 47,3 %. In conclusion, some possible reccomendations are designed, which are suitable in case of implementation of tuition-fees.

Fiscal rules in selected EU countries between 2004-2015: sensible method for consolidation of public finances or fad of politicians?
Veselý, Lukáš ; Strejček, Ivo (advisor) ; Chmelová, Pavla (referee)
The subject of fiscal rules is very topical issue. The rise of public debt in certain developed countries resulted in what is sometimes called "debt crisis". Debt of those countries which is higher than their annual gross domestic product is viewed as unpayable by some economists. The main objective of this thesis has been to prove or disprove hypothesis that the fiscal rules studied in this paper are an effective solution for public finance consolidation. This verification was based on the analysis of fiscal rules functioning in selected countries between 2004 and 2015. As per results of analysis the paper aims to give recommendations for the Czech financial constitution proposal. The actual results of inquiry proved the hypothesis. Well-chosen fiscal rules are the right way towards fiscal consolidation, provided they are observed. Fiscal rules making thus requires an emphasis to be placed on the well-formulated exit clauses altogether with prospective sanctions. The current Czech financial constitution proposal is built on the correctly picked fiscal rule type, although the reference value lacks economic sense and it would not lead, with a high degree of probability, towards fiscal consolidation.

Strategic Trade Policy in Defence and Security Industry
Neumannová, Pavla ; Žamberský, Pavel (advisor) ; Jiránková, Martina (referee)
The master thesis is devoted to a nontraditional, however, in the todays world to a very current topic, arms industry and its support. The thesis connects the theoretical concept of the strategic trade policy (defined by P. Krugman or J. Brander) to its practical interpretation and application in the defence and security industry. The first chapter explains the strategic trade policy using the Brander Spencer analysis. The topic of the second chapter is strategic industries and this chapter answers the question whether the defence and security industry is a strategic industry or not. The third chapter analyses the possibilities of the support of DSI and compares approaches of different EU member states. The last chapter is devoted to the solution of this problem. The main contribution of this thesis is a new interpretation of the strategic trade policy, analysis of the importance of the defence and security industry and its support and suggestion of practical measures for Czech companies and for the Czech Ministry of Defence.

Makroekonomický dopad mateřské (a rodičovské) dovolené ve srovnání České Republiky s Brazílií
Kalkusová, Marie ; De Castro, Tereza (advisor) ; Neumann, Pavel (referee)
This thesis aims to estimate the macroeconomic impact of maternity and parental/paternal leave in the Czech Republic and Brazil. In addition, the thesis stresses out the costs of Czech model application to Brazil and vice-versa. The first chapter brings a theoretical framework. It compares the analyzed policies in both countries and introduces the relevant terms. The second chapter estimates the costs of maternity and parental/paternal leave related to public expenditure and GDP for the years 2005-2014 and brings own simulation model for Czech model application to Brazil and vice-versa. The third chapter analyses the inefficiencies and suggest possible mitigation. The results show the costs of 0.71% of GDP and 1.66% of public expenditure in the Czech Republic and 0.50% GDP and 2.27% of public expenditure in Brazil in 2014. The Czech model applied in Brazil would be very costly and the opposite scenario would lead to the decrease of macroeconomic burden in the Czech Republic. The thesis also analyzes the influence of maternal and parental leave in other areas, such as labor market, where the current structure may penalize Czech women in long term. By this analysis, the thesis contributes to the current debate about the impact, the length and costs of maternity and parental leave.

Supervision of volunteers in nonprofit organizations
Beerová, Michala ; Kopecký, Martin (advisor) ; Šerák, Michal (referee)
The theme of the presented bachelor thesis is the process of supervision and the volunteerism. Volunteering is an important subject in today's society and essentials workforce in social work. The aim of this work is to focus on the non-profit sector and try to describe it. Furthermore, there is an explanation of the position of volunteers in these organizations and supervision in social work. Supervision is one of the managerial function in non-profit organizations, which is widely and long-term applied. The thesis wants to show basics, consequences and benefits of volunteer's supervision. Providing supervision is one of the main objectives of the organization to support staff or their volunteers. This bachelor thesis explores volunteering and supervision in two countries, the Czech Republic and Sweden. This thesis compares two different approaches, based on history of these two countries. Volunteering and supervision are very interesting features of the non-profit organizations. The practical part of this thesis comprises from qualitative investigation of different nonprofit organizations. The organizations were interviewed to get information about the purpose of the volunteering, educational potential of supervision and the current situation of volunteer supervision there. The aim of this investigation...

Emergency preparedness and protection of the inhabitans in the national company Budějovický Budvar in the release of hazardous substances
JIRKA, Martin
The thesis describes the issue of emergency preparedness and protection of the inhabitants in the National Corporation Budweiser Budvar during the release of hazardous substances. The thesis is focused on important aspects that determine the drafting of emergency documentation. One of aspects is the amount of hazardous chemical - ammonia. The total ammonia content in the object is 22 tons. This amount is according to the Act No. 59/2006 Coll., concerning prevention of major accidents as a sub-limit amount and not as an object into group A or B. On these not-classified resources are not subject to some duties under this Act, especially the obligation to prepare an emergency documentation (except where the regional authority include in the emergency plan then must provide and update the required documents). This paper doesn´t discuss by the massive leakage of 22 tons of ammonia. On the basis of analyzes were identified two sources of the risk. The first is a reservoir about the content of 10 tons which is located on the roof of the engine room. Maximum real filling is around 6 tons. The second source of risk is an expansion tank about the content of 14 tons, which is located in the building with cylinderconicals tanks (CKT). Considered fulfillment of the expansion vessel is about 7 tons. Although in this case is not about buildings and facility in which is treated with such a amount of dangerous chemical substances, which would belonged to the relevant group, I will perform available analysis according to a regulations issued or supportively used to analysis and risk assessment in according to the Act No. 59/2006 Coll., concerning prevention of major accidents. Harmful effects of ammonia are another important aspect. According to the Notice of the Ministry of Interior No. 103/2006 Coll., concerning establish principles defining the emergency planning zone and the extent and method of preparation of an external emergency plan, ammonia is taken as moderately toxic substance that irritates the eyes, mucous membranes, and in high concentrations can cause death. The great advantage from the point of view of the protection inhabitants are the warning properties. Characteristic pungency is already known in very weak concentrations. Also disposal of hazardous concentrations isn't technologically challenging, due to its solubility in the water. Another dangerous effect, except the toxicity is its explosiveness (explosive limit from 15 to 28 %) and flammability. Fortunately controlled condensing pressure prevents ignition and explosion of ammonia. Risk of the explosion and ignition of ammonia isn´t analyzed in this thesis, because the range of effects caused by leakage of several tons, is from a toxicological point of view more threatening. Impacts of hazardous concentrations aren´t threat only for people but also for animals and the environment. The thesis focuses on the analysis and evaluation of risks. The results of this research are an important element of the draft of emergency documentation. During the processing is calculated with methods IAEA-TECDOC-727, Dow's Chemical Exposure Index, Estimation of toxicity and software modeling program ALOHA. Further research is being done by brainstorming and semi-standardized interviews with employees of the company. In conclusion of the thesis is appropriate the drafting of emergency cards and emergency documentation (although not in range under the Act of concerning prevention of major accidents), according to which the reaction proceeded for any leakage of dangerous chemicals (ammonia) into the environment and the protection of workers which occur at the public premises or in the premises of the zone of impact of ammonia spilled outside the area Budweiser Budvar, NC. The use of the draft of emergency documentation is also conditioned by the location of the object in relatively densely populated areas of the county town of České Budějovice.

Míry podobnosti pro nominální data v hierarchickém shlukování
Šulc, Zdeněk ; Řezanková, Hana (advisor) ; Šimůnek, Milan (referee) ; Žambochová, Marta (referee)
This dissertation thesis deals with similarity measures for nominal data in hierarchical clustering, which can cope with variables with more than two categories, and which aspire to replace the simple matching approach standardly used in this area. These similarity measures take into account additional characteristics of a dataset, such as frequency distribution of categories or number of categories of a given variable. The thesis recognizes three main aims. The first one is an examination and clustering performance evaluation of selected similarity measures for nominal data in hierarchical clustering of objects and variables. To achieve this goal, four experiments dealing both with the object and variable clustering were performed. They examine the clustering quality of the examined similarity measures for nominal data in comparison with the commonly used similarity measures using a binary transformation, and moreover, with several alternative methods for nominal data clustering. The comparison and evaluation are performed on real and generated datasets. Outputs of these experiments lead to knowledge, which similarity measures can generally be used, which ones perform well in a particular situation, and which ones are not recommended to use for an object or variable clustering. The second aim is to propose a theory-based similarity measure, evaluate its properties, and compare it with the other examined similarity measures. Based on this aim, two novel similarity measures, Variable Entropy and Variable Mutability are proposed; especially, the former one performs very well in datasets with a lower number of variables. The third aim of this thesis is to provide a convenient software implementation based on the examined similarity measures for nominal data, which covers the whole clustering process from a computation of a proximity matrix to evaluation of resulting clusters. This goal was also achieved by creating the nomclust package for the software R, which covers this issue, and which is freely available.
