Experiment CAPEX-U: Současnost a Budoucnost
Frolov, Oleksandr ; Koláček, Karel ; Štraus, Jaroslav ; Schmidt, Jiří ; Boháček, Vladislav ; Prukner, Václav
A new pulse capillary discharge driver with a laser-triggered main spark gap has been developed. The assembled CAPEX-U device consists of a Marx generator, of a pulse forming line, a gas-filled laser-triggered spark gap and a ceramic capillary. Its design was supported by mapping of electrostatic fields in the most exposed regions and by analysis of an equivalent circuit. Operation of the laser-triggered spark gap was tested on a single-channel model. In the paper, the results of the modelling and of the first electrical tests of the whole device (capillary current and voltage at the end of pulse forming line) are presented.

Analysis of the EU regulations in the field of Information and Telecommunication technologies and their effect on the single market
Hart, Ludvík ; Procházka, Pavel (advisor) ; Strejček, Ivo (referee)
The bachelor thesis describes the EU regulations in the field of information and communication technologies (ICT), particularly the Digital agenda for Europe strategy. These regulations are then tested for their influence on the European single market. The major question answered here is whether the EU regulations in field of ICT have a positive impact on the EUs single market. Answer to this question helps us evaluate the ongoing Digital agenda strategy. The impact of the regulations is analysed by induction of the following indicators, international trade, ratio of population buying online, DESI index and NRI index. With this method it is possible to tackle the wide range of fields the Digital agenda covers. I conclude this work with the statement, that European ICT regulations do have a positive impact on the single market, although are problematic due to the slow legislative process and low efficiency in addressing the regulated issue.

Povrchová aktivita osmi běžných druhů chvostoskoků ve smrkových lesích a na pasekách po kůrovcové kalamitě v Národním parku Šumava, Česká republika
Brůhová, Jindřiška ; Rusek, Josef
Surface activity of eight common epigeic species of Collembola were studied in spruce forests, dead spruce forests and clearings in the Šumava National Park, South Bohemia, Czech Republic: .i.Lepidocyrtus lignorum, Leidocyrus cyaneus, Pogonognathellus longicornis, Tomocerus minutus, Tetracanthella stachi, Allacma fusca, Entomobrya nivalis, Dicyrtomina minuta./i.. Five pitfall traps were exposed at each of the 9 sites in the summer and autumn periods to study the impact of spruce forest die-off after bark beetle attack (dead forests) and on clearings. Material comprising 79435 specimens was evaluated in this study using the non-parametric Kruskal-Wallis test for comparing Collembola activity between the sites and seasons. Complete linkage (Euclidean distances) cluster analysis was used for comparing the collembolan activity in all nine sites.

Empirical analysis of Okun’s law in Iceland
Zajíček, Zdeněk ; Slaný, Martin (advisor) ; Chytilová, Helena (referee)
This thesis deals with empirical analysis of Okuns law in Iceland. Okuns hypothesis of negative relationship between real GDP and the rate of unemployment is being tested on two models, difference and gap, using OLS estimation. Also there are two filtration methods used (Hodrick-Prescott and Baxter-King) for gap model estimation. The results of all models showed weak relationship of variables, but proved the hypothesis. In the following part, the same procedure is being used on Finlands data, to get comparison of coefficients. Results for Finland showed weaker bond of variables than in Iceland, but the Okuns hypothesis still holds. Last part is focused on finding the sensitivity of rate of unemployment to changes in added value of each economical sector in Iceland using the production approach model. This model gave inconclusive results due to insufficient data available.

Analysis of the emarketing strategy of the company Europ Assistance s.r.o.
Egert, Michal ; Sedláček, Jiří (advisor) ; Kostaš, Jurij (referee)
This thesis analyzes the e-marketing strategy of the company Europ Assistance s.r.o and compares it with its competitiors. First part of this work presents the company and its products. The second part analyzes the products and web presentation of the competitors. The final chapters then deal with the analysis of the website and communication strategy of the company Europ Assistance. Findings in the individual chapters are compared with the competitors. The thesis also includes user testing of individual company websites by users who have never seen the website. This testing provides valuable information for improving the structure and content of the site. Result of this thesis is the evaluation of the strengths and weaknesses of the e-marketing strategy of the company Europ Assistance s.r.o.

The analysis of price elasticity of demand for beer
Hromadníková, Kateřina ; Mirvald, Michal (advisor) ; Babin, Jan (referee)
The thesis analyses price elasticity of beer demand. Hypothesis about inelastic demand is tested first for nationwide level and then on data of specific brewery. Elasticity was determined by regression analysis, specifically by ordinary least squares with all variables expressed in logarithmic form. Consumption of beer is the endogenous variable and price of bottled beer (price of one hectoliter of beer in case of brewery), average gross income and price level are in the role of the exogenous variables. The hypothesis about inelastic demand was successfully proved. Price elasticity estimates range from -0,66 to -0,2. In case of specific brewery price was not significant. On the other hand, average gross income seems to be the significant determinant. According to income elasticity beer seems to be luxury good in case of specific brewery and necessity in case of nationwide level.

Memes and the Theory of Universal Darwinism
Havlík, Vladimír
The article deals with the philosophical presuppositions and groundwork of the memetics. The central question is an analysis of Universal Darwinism as a common and universal evolutional principle or pattern that always springs in every environment when there're fulfilled required conditions. An evolutional process could be possibly described like an algorithmic process that faces to the rise of organized orderliness. Darwinism in this generally universal sense points to a distinctness survival of any kind self replicated code of information that has some influence over its probability of replication. The article stresses methodological importance of memetics as it makes possible to introspect variety of cultural development from a simple unification perspective.

Fatigue properties of AZ61 magnesium alloy
Provazníková, Andrea ; Juliš, Martin (referee) ; Pantělejev, Libor (advisor)
This master’s thesis is dealing with low-fatigue behavior of magnesium alloy AZ61, prepared via squeeze casting method. The main aim of this work was to obtain the basic mechanical properties as well as the low cycle fatigue data. Additional metallographical evaluation of microstructure and fractographical analysis after fatigue tests was made.
