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,...

Profile and analysis of the relationship between strength and speed of American football players
Louda, Petr ; Malý, Tomáš (advisor) ; Hojka, Vladimír (referee)
Title: Profile and analysis of the relationship between strength and speed of American Football players. Aims: The main aim of this study was to analyse the profile and relationship between strength and speed of American Football players. The research was taken to find, to what extent does strength and speed correlate including the test battery and if so, does the higher level influence results of the motoric tests. Methods: In our research we applied methods of analysis and comparison. The method of analysis was used in detailed breakdown of the measured results of the motoric tests. The comparison method was used to determine relationships between specific motoric tests. We carried the basic statistical processes of the measured data, which included calculation of the measurement of arithmetic mean, mode, median, minimum and maximum value, upper and lower quartile and variables. Range of scatter, deviation and quartile range together with variation coefficient. Relationships between motoric tests have been calculated by Pearson's correlation coefficient. Results: Statistically significant correlations were found between the tests of linear speed - 10 and 40 yard dash (r = 0.86) and tests of agility- 20 yard shuttle a 3 cone drill (r= 0.77). The correlation approached significance between other...

Comparison of performance tests results determined during kayak spiroergometry with achieved kayak paddling performance
Štěrba, Jan ; Bílý, Milan (advisor) ; Doktor, Martin (referee)
- 6 - Abstract Title: Comparison of performance tests results determined during kayak spiroergometry with achieved kayak paddling performance. Objectives: The aim of the study was to determine relationships between functional parameters values found during kayak spiroergometry and sport performance at 1000 meters distance, and how are these relationships going to change based on training period. Methods: To determine statistical dependence between sport performance at 1000 meters distance and choosen factors of sport performance, the correlation research was used - as a variable-dependent value the final result of sport performance at 1000 meters distance was used, as a variable-independent amounts functional parameters values found during kayak spiroergometry were used. To discover the statistical dependence methods of Pearson's correlation coefficient and regression analysis were used. Results: General level of kayak-athletes from testing file indicated by functional parameters values and demonstrated by kayak spiroergometry performance depends on kayak- athlete's level of sport performance at 1000 meters distance in prepared-training period only, when importance for general condition is emphasized. We did not discover the same phenomenon based on pre-racing period testing results. Sport performance at...

The Use of Statistical Methods for Data Processing
Čupr, Jiří ; Klučková, Martina (referee) ; Novotná, Veronika (advisor)
This master's thesis is focused on problem of orders of ingredients in McDonald's. It's an analysis of usage changes depending on outside temperature. Thesis includes theoretical background for correct analysis of the problem and possibilities to figuring it out. There is also an algorithmus for more efficient solution of problem with needs or excess of ingredients. There is also a program written in VBA language, that makes more simple usage of this algorithm on restaurants.
