The Reliability of Measuring on the Skytec Interactive Ski Simulator
Novotný, Otomar ; Jindra, Matouš (advisor) ; Fořterová, Petra (referee)
Title: The Reliability of Measuring on the Skytech Interactive Ski Simulator Objectiv: The goal of this work is to investigate the reliability of the measurement of energy expenditure on the Skytech Interactive Ski Simulator. Methods: The sample consisted of 14 subjects, among which were 9 boys and 5 girls. The value of energy expenditure was measured by indirect calorimetry using the energy equivalent and respiratory exchange ratio. For the measurement of respiratory gases, the Metamax 3B metabolic analyzer and for the analysis of heart rate, the Polar S610 heart rate monitor were used. The subjects completed two measurements, each lasting 6 minutes. During this time, the data needed for subsequent calculations reliability were measured. Assuming that the pair of measuring has a two-dimensional distribution, the reliability equals the correlation coefficient. It was computed using the maximum likelihood method. Results: The measurement of energy expenditure on the Skytec Interactive Simulator provided consistent and reliable results. The findings in this study can be applied to further testing on this machine. Conclusion: The reliability of energy expenditure reached 0,84, a result better than the usual values of reliability tests, which may typically be about 0,8. Keywords: Energy expenditure,...

Evolutionary Optimisation of Analogue Circuits
Mihulka, Tomáš ; Zachariášová, Marcela (referee) ; Bidlo, Michal (advisor)
The aim of this work was to create a system for optimisaton of specific analog circuits by evolution using multiple fitness functions . A set of experiments was run, and the results analyzed to evaluate the feasibility of evolutionary optimisation of analog circuits . A requirement for this goal is the study and choice of certain types of analog circuits and evolutionary algorithms . For the scope of this work , amplifiers and oscillators were chosen as target circuits , and genetic algorithms and evolutionary strategies as evolutionary algorithms . The motivation for this work is the ongoing effort to automate the design and optimisation of analog circuits , where evolutionary optimisation is one of the options .

Comparison of Democratic Consolidation in Former Eastern Bloc
Bárta, Vít ; Houda, Přemysl (advisor) ; Vaňous, Jaroslav (referee)
The aim of this thesis is to numerically evaluate democratic consolidation in Eastern European countries of the former Eastern Bloc. To compare these countries with each other and decide which of these countries can be considered as consolidated democracies. Secondary aim is to find which factors supported this consolidation or at least correlate with it. Theoretical basis of this work is Wolfgang Merkel's theory of democratic consolidation. He divides democratic consolidation into four levels: constitutional consolidation, representative consolidation, behavioral consolidation and democratic consolidation of the political culture. Each level of democratic consolidation is numerically expressed, with usage of Bertelsmann's transformation index data, separately for all states in two-year intervals since 2005 to 2015. Based on that, overall democratic consolidation is calculated. Therefore, we can compare countries between each other and in time. Correlation between factors supporting consolidation and overall democratic consolidation is expressed by Pearson correlation coefficient. This work is beneficial in creating and describing method, which can be used for numerical expression of democratic consolidation in any state since 2005 to 2015 without author's subjective influence. Another benefit is...

Patterns of the electoral behavior of voters in the Usti Region
Měska, Ondřej ; Švec, Kamil (advisor) ; Švec, Radek (referee)
The main goal of this bachelor thesis is to try to find out a formula of electoral behavior of voters in region Ústí nad Labem using a correlation analysis. In the first part of the thesis its author introduces regional differences related to specific variables or election results. In the second part a large dataset is made on a municipality level and applied to a disctricts' level subsequently. A goal of the thesis is to find out a correlation between election results of four chosen political parties (ČSSD, ODS, KSČM, DSSS) in elections to Parliament of the Czech Republic in years 2010 and 2013, and a voters' socioeconomic status using the obtained dataset. The conclusion of the thesis reveals whether we could expect any specific election results of selected political parties based on voters'socioeconomic status and also to find out a formula for voters' behavior.

Influence of selected conditional factors on performance in white water slalom
Vondra, Jan ; Bílý, Milan (advisor) ; Kratochvíl, Jiří (referee)
Title: Influence of selected conditional factors on performance in white water slalom. Aims: The aim of the study was to investigate the relationship of selected specific movement abilities being examined modified test battery with the performance of athletes in the water slalom. Methods: It was used field measurements where the applied modified test battery. Using GPS module to determine the distance partial tests from batery. For measuring was used manual measurement. To determine the statistical correlation between the modified battery and performance ability of competitors was used two different coefficients of correlation and regression analysis. According to the order of the test and the race was used nonparametric correlation study - Spearman correlation coefficient. Determining the statistical significance of the relationship of measured times in tests and final time in the nomination races have used the Pearson correlation coefficient. Results: For a statistically significant relationship was determined value when r ≥ 0.8. Spearman's correlation coefficient: In the test at 40 m were obtained these correlation coefficients: Nomination races rs = 0,380952, Czech cup rs = 0,595238. In the test at 80 meters they were obtained these correlation coefficients: nomination races rs = 0,857143,...

Subjective evaluation of background noise in audio systems
Falešník, Vlastimil ; Mach, Václav (referee) ; Rášo, Ondřej (advisor)
In this bachelor thesis, the effect of additive background noise on audio recordings was researched. This kind of noise often occurs when these recordings are being restored. The most frequent effort is to suppress these unwanted noises. While suppressing the noises, the most problematic part is that it always depends on subjective evaluation of the listener. Practical impacts of these noises were researched throughout two listening tests. Afterwards, it was necessary to choose proper (ordinal) evaluating scale. The listening tests established the subjective assessment of jammed additive noise degree. Finally, the effect of selected parameters on subjective perceived quality was determined.

The data analysis on perception of quality of life in European cities
Pulcová, Petra ; Jarošová, Eva (advisor) ; Pecáková, Iva (referee)
This bachelor's thesis is about data analysis on perception of quality of life in European cities based on survey, which was made in 2009 by European commission. Theoretical part is focused on explaining the concept of quality of life and basic methods of correlation analysis. At the end is dissertating about some methods for determining order of units by more than one benchmark.
