Resistance of HDPE materials against crack propagation from two-parametric fracture mechanics point of view
Bareš, Pavel ; Fiedler, L.
The influence of geometry constraint on the resulting values of fracture characteristics of HDPE material is analysed. To this aim the crack growth resistance (J-R) curves and the initial fracture toughness values for HDPE material were experimentally determined for an arc-shaped test specimen with and without protective layer. Two parameter fracture mechanics is applied and transferability of the experimental data to the two-layer pipe used in praxis is discussed. Finite element calculations were used for the investigation. It is concluded that the estimation of the service life of pipes based on the approach is conservative.

Is import of goods from european countries to Czech republic more or less influenced by changes in nominal and real exchange rates than in non european countries?
Vereš, Jan ; Stroukal, Dominik (advisor) ; Slaný, Martin (referee)
This bachelor thesis analyses the connection between import of goods from foreign countries to Czech Republic and the exchange rate changes. The initial hypothesis of this paper is to prove that the depreciation of domestic currency has positive influence on balance of trade balance. For this purpose there is eight econometric models which were created by using time series from years 2003 to 2016. These models are divided in pairs among four chosen countries. For each country two models were created that follow the development of trade balance between Czech Republic and one of the countries in two different time frames. All the models always use the real effective exchange rate, growth rate of GDP for Czech Republic and growth rate of GDP for one of the countries as explanatory variable. It is connected with the second task of this thesis, which is the analysis of the differences in the behaviour of the models that belong to the countries which are members of the EU and these that are not. The aim is to find out whether the existence of tariffs on imported goods from countries out of the EU causes visible differences in the behaviour of the variables that were included in the models. Based on the outcomes of all eight models the main hypothesis has been proved right for three out of four countries. In the models for Germany, China and France the relation of real exchange rate and trade balance came out as positive in long term, in short term the outcome was ambiguous. The second question of this thesis has been answered, but its added value is questionable. The final models for each state do show some noticeable differences and they can be used to determine if the influence of the change of exchange rates on trade balance is smaller or bigger in the countries where tariffs are used. On the other hand, from the results we can learn that the sample of only four countries is insufficient for the deduction of any conclusions.

Unconvential monetary policy adopted by ECB and FED in 2008-2015
Pörner, Marek ; Šetková, Lenka (advisor) ; Ševčíková, Michaela (referee)
The main aim of this thesis is to analyse the accomplishment of the goals set, namely those of the selected unconventional monetary policies approved by the Federal Reserve System and the European Central Bank in response to the last financial crisis. With the FED the attention is focused on Quantitative Easing, whereas with the ECB it is focused on the programmes called Enhanced Credit Support, SMP, OMT and EAPP. Important parts of this thesis are also the explanation of the transmission mechanism of the unconventional monetary policy, the evaluation of macroeconomic impacts of these non-standard tools, the comparison of procedures of the two monitored central banks, but mainly the analysis of selected risks related to those tools. The principal method was an empirical analysis supported by economic studies dealing with the issues mentioned above. In the thesis it was discovered that the individual goals of the monitored programmes were achieved (with the exception of the SMP). With the programme EAPP no conlusion can be drawn because the programme has not been finished yet. Nevertheless, these non-standard tools bring certain risks such as a creation of a bubble in the markets of assets, a redistribution of wealth, a spillover effect, etc. For that reason it will be possible to evaluate the overall effect of the unconventional monetary policies only after a longer time period.

A Comparison of Two Models of the Energy Market Development in Czech Republic from 2015 to 2040
Dvořáková, Jitka ; Zeman, Martin (advisor) ; Lukášová, Tereza (referee)
The bachelor thesis is focused on the prediction of the energy market in the Czech Republic between 2015 and 2040 and on the comparison of potential costs related to two models of energy portfolio management. The first model was created according to the National Energy Concept from 2014, while the other one was designed artificially to simulate usage of the renewable resources in 50% of the electric energy production. The theoretical part of the thesis discusses the recent situation of the Czech energy market, defines types of energy resources and explains terms related to the discussed topic. In the practical part, direct production costs of different kinds of power plants were computed and used to estimate economic demands of the two considered models. The efficiency of both models was compared and evaluated. The aim of the thesis was to decide, which of the two models would be more favourable for the Czech national economy. Key words: energy, energy market, direct costs, economic advantage JEL classification: Q40, Q41, Q43, Q47

Consumer Credit in the Czech Republic from the Client’s Perspective
Huleš, Matěj ; Hejda, Jan (advisor) ; Kaczor, Pavel (referee)
The aim of the thesis titled Consumer Credit in the Czech Republic from the Client´s Perspective is the analysis of the offer of consumer credit loans in the Czech market and an explanation of the basic problems of consumer credit. The first part explains basic information and theoretical concepts related to the issue. In the second part of the thesis, these concepts are put into practice and two model examples are used to explain the procedure for selecting a credit product that will meet the consumer´s needs. The section deals with the comparison of these products. Credit loans are subjected to the comparison in terms of total costs and sub-parameters of the loans, which affect the costs. Following the results of the comparison, the conclusion contains practical recommendations for consumers. The thesis results in a comprehensive educational text that will help anyone interested in consumer financial products to make their choice.

Systém odměňování v malém IT podniku
Novotný, Lukáš ; Dvořáková, Zuzana (advisor) ; Cetkovský, Pavel (referee)
The topic of this thesis is reward management and its application in a small-sized IT enterprise. Its goals are to properly document and describe current reward system in the company, evaluate the system and recommend improvements for the system. The first two goals are reached via thorough research of the company through semi-structured interviews, employee satisfaction survey, participant observation and document examination and the last one by applying principles from the current literature and education to the results of the two previous goals. The findings are that the reward system, despite growing organically instead of designed, is relatively effective in some areas, but needs improvement in other areas. The main improvement areas are motivation by contingent pay, communication management and performance management. Relatively well working rewards are especially non-financial reward connected to the work environment and work itself.

The Controlling Study
Herda, Tomáš ; Mikovcová, Hana (advisor) ; Herda, Zdeněk (referee)
The main goal of this Diploma´s Thesis is to make a model for calculation of water and sewer rates for the company Vodovody a kanalizace Náchod, a.s. when sticking to the set criteria both from the side of VaK Náchod, a.s. and law regulations. Based on the theoretical part an analysis of customer sensitivity to the price changes using the data for last 20 years follows. Findings from the first two parts are used in risk analysis in next part. The created model calculates the water and sewer rates based on the information from the company accounting system in the way to generate sufficient financial resources to fulfill the renovation plan of infrastructural property plant and equipment and to transfer given amount to the company funds. In addition, the model monitors whether the legal condition of maximal allowable increase of profit per m3 is met. In the customer sensitivity to the price changes part the price elasticity of demand for water and sewer rates is calculated based on the data from 1995 to 2015. The assumption of inelastic demand is confirmed. Risk analysis part is deals with potential risk regarding the demand and prices. Potential impacts for the most significant risk are quantified. The analysis uses knowledge gained in the first two parts. It was confirmed that potential risks are exiting but do not have any significant impact on the going concern of VaK Náchod, a.s. The created model has been already used for the calculation of prices for the year 2017. Customer sensitivity analysis to the price changes and link to the potential risks is an additional information for VaK Náchod, a.s. which validates that nowadays, there are no significant threats which could affect the demand and water and sewer rates significantly.

Interspecific hybridization in Acrocephalus warblers.
Majerová, Veronika ; Reifová, Radka (advisor) ; Kotlík, Petr (referee)
Acrocephalus warblers have gone through the adaptive radiation during last severalmillion years, which gave rise to thirty one species occupying mainly Eurasia,Africa and Australia. The majority of species are morphologically very similar,however, they differ in ecological requirements, migration strategy, and song.Interspecific hybridization seems to be quite common among Acrocephaluswarblers, not only between sister species, but also between more distantly relatedtaxa. The main goal of this study was to determine whether this hybridization leadsto gene flow between species and which factors affect the rate of interspecific geneflow. For this purpose we conducted population-genetic analysis in three Europeanspecies of the Acrocephalus warblers of the subgenus Notiocichla: reed warbler (A.scirpaceus), marsh warbler (A. palustris), and blyth's reed warbler (A. dumetorum).Our results based on the analysis of sequence data from eight nuclear loci indicate,that gene flow between the studied species occurs, but only in one direction. Thegene flow is higher between genetically more related species than betweenecologically more similar species. We also estimated that the reed warbler and themarsh warbler diverged approximately 1,1 million years ago. The blyth's warblerand ancestor of the reed and marsh warbler...
