Determining person's height from spoken utterance
Pelikán, Pavel ; Mekyska, Jiří (referee) ; Atassi, Hicham (advisor)
Diploma’s thesis is focused on determining person’s height from spoken utterance. First part of the work evaluates present situation and refers to the published studies. Knowledge gained in these studies was used in this thesis. Study with the best results according to estimated height of the speakers was chosen. The experiment realized in the chosen study was performed in this work. The system for the estimation of the height of the speakers based on the speech signal was created. This system was successfully tested by using several acoustic features on spoken utterances from TIMIT database.

Deconvolution of hemodynamic response from fMRI data
Bartoň, Marek ; Kolář, Radim (referee) ; Havlíček, Martin (advisor)
This paper deals with the variability of HRF, which may have crucial impact on outcomes of fMRI neuronal activation detection in some cases. There are three methods described - averaging, regression deconvolution and biconjugate gradient method - which provide HRF shape estimation. In frame of simulations regression method, which uses B-spline curves of 4-th order for window length of 30 s, was chosen as the most robust method. Deconvolution estimates was used as HRF models for classic analyse of fMRI data, concretely visual oddball paradigm, via general linear model. Enlargement of localizated areas was observed and after expert consultation with scientific employees from neurology clinic, outcomes was evaluated as relevant. Furthermore Matlab application, which provides confortable observation of HRF variability among brain areas, was made.

Buchal, Matěj ; Fischer, Jakub (advisor) ; Helman, Karel (referee)
The bachelor thesis is based on empirical research of criminality in the Czech Republic. The object is to describe incidence of criminal offences in regions of the Czech Republic in 2014, to discover dependence of criminality on various socioeconomic factors by using regression and correlation analysis and to estimate future development of number of criminal offences. In the last part there is study of influence of the former president Vaclav Klaus amnesty on development of criminality in 2013 and 2014.

The relationship between malware attacks and the popularity of operating systems
Jirmusová, Radka ; Gála, Libor (advisor) ; Čermák, Igor (referee)
The Bachelor thesis deals with the issue of malware and operating systems. The scope of the work is to prove or disprove the relationship or dependence between the number of malware attacks and different operating systems using statistical calculations. The goal of this thesis is achieved on the basis of methodology of analysis. The thesis presents the result of the analysis used to summarize the conclusions. The work is divided into four main parts. The first part introduces the issue of malware to the reader. The second section intoduces operating systems used in the analysis. The third part defines the relationship between the malware and information technology. The final section deals with statistical calculations and achieved results. Own contribution of the thesis is to evaluate the dependencies in the monitored areas.

The development of tax collection from personal income tax in the Czech Republic
Šubová, Lucie ; Láchová, Lenka (advisor) ; Kouba, Tomáš (referee)
This diploma thesis analyses the development of tax collection from personal income tax in the Czech Republic from 2000 to 2012. The first chapter describes the tax reforms that took place in the period in the Czech Republic. Furthermore, it describes the relationship of collection and GDP. In the second chapter I analyse the PIT collection as whole. By regression and correlation analysis I shall identify the relationship and the degree of dependence between collection and different variables such as GDP, the number of taxpayers, unemployment and sub-collections. In the third chapter, the PIT collection is divided into three sub-collections -- levied on tax returns, from employment and withholding. Each of the sub-collection is analysed separately. I describe factors that in a given year or in group of years the most influenced their size. By regression and correlation analysis I shall identify the relationship and the degree of dependence between the sub-collections and GDP. Likewise, I shall identify the relationship and the degree of dependence between the sub-collections each other. In the last chapter the PIT collection is divided by individual financial authorities, ie by region. The development of tax collection in each region is analysed and by regression and correlation analysis is detected the relationship and the degree of dependence between the regional collections and GDP.

The assessment of price developments of pork meat in selected EU countries
HAUZEROVÁ, Jana
The main objective of this work is to analyze the prices of pork in selected EU countries in the period 2003-2013. This work consists of several parts. In the first part dealt with theoretical issues - agriculture sector, and therefore the Czech agriculture, the issue of the pricing in agriculture. The last part of the theoretical part contains a comparison of costs and revenues on a pig.The second part is called the methodology, this section contains instructions for calculations that are performed in solutions and results. The third part contains the results of calculations, because the prices of agricultural producers were used per 100 kg live weight and average annual wages. At the end of the work are collected all the results obtained in this work results.

Demand for cinemas - what determines the consumer behaviour?
Řeháková, Petra ; Mičúch, Marek (advisor) ; Kovanda, Lukáš (referee)
The main aim of this diploma thesis is to identify the determinants of behavior of demand for multiplexes in Prague. The main building material is the dataset of attendance and revenues evolution for individual movies distributed between years 2002 and 2011, always for the first four weeks from the premiere, provided by the Union of Film Distributors. The paper investigates consumer behavior on the movie market. The demand for movies is the dependent variable measured by the number of visitors in the corresponding weeks. The subject of analysis -- explanatory variable - is price, film rating (critics), genre, country of origin, character of time frame, frequency of screenings in a given week, format (2D/3D), length of movie, popularity of the actor/director, impact of movie series etc. The data are exposed to the regression according to which the significance of different variables is tested. The hypothesis about strong negative correlation of the price and quantity demanded is investigated based on the results, (Dewenter R., Westermann M., 2005) versus the hypothesis of weak sensitivity those two variables (Sangho Kim, 2009) against a more significant relationship of demand and other determinants. The influence of price on attendance has shown to be insignificant on the Prague movie market in the short term. A significant determinant impacting the attendance for a movie in the entire monitored period is the film rating, actor, length of movie, and number of screenings.
