Investigation of correlation between arc voltage and arc movement
Szotkowski, Šimon ; Valenta, Jiří (referee) ; Kloc, Petr (advisor)
The electric arc burns in an ionized gas and is divided into AC and DC arc according to the power supply. The electric arc is conductive, so to turn off the electric circuit, the arc must be extinguished as soon as possible. Arc breakers are used to extinguish the arc. Arc breaker must be designed to withstand the increased pressures and temperatures caused by the arc. The purpose of the bachelor's thesis was to design and construct a arc breaker with the possibility of monitoring the movement of the arc with a high-speed camera. From the measured data, the dependence between the arc voltage and the movement of the arc root was determined by correlation analysis. Correlation analysis is used to calculate the possible existence of a dependence between two quantities with the correlation coefficient and testing.

Development of modern acoustic features quantifying hypokinetic dysarthria
Kowolowski, Alexander ; Zvončák, Vojtěch (referee) ; Galáž, Zoltán (advisor)
This work deals with designing and testing of new acoustic features for analysis of dysprosodic speech occurring in hypokinetic dysarthria patients. 41 new features for dysprosody quantification (describing melody, loudness, rhythm and pace) are presented and tested in this work. New features can be divided into 7 groups. Inside the groups, features vary by the used statistical values. First four groups are based on absolute differences and cumulative sums of fundamental frequency and short-time energy of the signal. Fifth group contains features based on multiples of this fundamental frequency and short-time energy combined into one global intonation feature. Sixth group contains global time features, which are made of divisions between conventional rhythm and pace features. Last group contains global features for quantification of whole dysprosody, made of divisions between global intonation and global time features. All features were tested on Czech Parkinsonian speech database PARCZ. First, kernel density estimation was made and plotted for all features. Then correlation analysis with medicinal metadata was made, first for all the features, then for global features only. Next classification and regression analysis were made, using classification and regression trees algorithm (CART). This analysis was first made for all the features separately, then for all the data at once and eventually a sequential floating feature selection was made, to find out the best fitting combination of features for the current matter. Even though none of the features emerged as a universal best, there were a few features, that were appearing as one of the best repeatedly and also there was a trend that there was a bigger drop between the best and the second best feature, marking it as a much better feature for the given matter, than the rest of the tested. Results are included in the conclusion together with the discussion.

Prostorová diferenciace výskytu prostituce ve světě
ŠOUREK, David
The bachelor thesis deals with the spatial differentiation of the occurrence of prostitution in the world at the level of states. The number of prostitutes is based on the latest UN estimates. It is supplemented by other sources for the widest possible set of data. The analysis is focused on the comparison of prostitution rate with selected socioeconomic indicators by applying correlation coefficients to clarify the effects on the examined phenomenon. At the same time, emphasis is placed on the interpretation of differences and the spread of prostitution in the world. The synthetic part deals mainly with the distribution of prostitution in the macro-regional concept of the Earth in order to generalize the results and describe the main determinants of prostitution.

Government investment in the Czech Republic
RENDLOVÁ, Šárka
Investments significantly affect development of economy in both short-term and long-term periods. The income effect of investment has a short-term impact on the aggregate demand. Aggregate supply is influenced by the capacity effect and it only manifests in a long-term period. Many studies analyse development of government investments. Some of these analyses are cited in this work, which compares various determinants that have an impact on the size and dynamics of government investments. Preliminarily it is possible to conclude that the main determinants are economic, fiscal policy, political-economical factors. For example, in the times of economic crisis government investments are first expenditures to cut. The aim of this work is how the mentioned factors affect growth and development of the investments in the Czech Republic. In empirical analysis the data from Eurostat for period 1995-2016 are used and they are also examined in terms of size, development and structure. Then the correlation analysis is used to examine how much selected factors influence investments. After correlation analysis the regression analysis is used for generating resulting models.

The impact of electric vehicles on the automobile industry
Pavelková, Adéla ; Chytilová, Julie (advisor) ; Žigraiová, Diana (referee)
The main aim of this bachelor thesis is to identify the current and future importance of the electric vehicles. Apart from global situation, it also investigates the development in China, Europe, Norway and the U.S. To see the future position of electric vehicles on the automotive market, trend analysis and Bass Diffusion Model were used. The results showed that in the year 2035, the share of sales of electric vehicles will slowly approach a threshold of 50% in all analysed regions. The exception is Norway where the market of electric vehicles is already developed. Next, the correlation analysis was applied to measure the relationship between the sales of electric vehicles and internal combustion engine vehicles. It was shown that the correlation is relatively strong with the same direction. The sales are influenced by similar factors. Furthermore, the correlation analysis was used to detect the relationship between the sales of electric vehicles and price of gasoline. The coefficient was positive. At the end, the regression analysis was applied to measure the cross elasticity of demand between electric and internal combustion engine vehicles. It was proved that these vehicles are substitutes. That means that the price of internal combustion engine vehicle can affect the sales of electric vehicles.
