Water cooling intensity prediction for given thickness of oxide layer
Haluza, Vít ; Hrabovský, Jozef (referee) ; Pohanka, Michal (advisor)
This diploma thesis is dealing with the impact of oxide scales on heat conduction. One of the main tools that were used are numerical simulations. Heat conduction is modelled by solving partial differential equations. Regression models and artificial neural networks are used for the prediction of the influence of oxides on cooling intensity. Determination of the conditions when the cooling was intensified and comparison of individual methods of prediction are the main results of the thesis.

Statistical data evaluation
Fadrný, Tomáš ; Koška, Petr (referee) ; Maroš, Bohumil (advisor)
This diploma thesis evaluates and processes data from final device checks. All the devices are similar types of thermal overcurrent relays by the ABB company. For appropriate statistical data processing, the Minitab 14 statistical software was used and various statistical methods were applied. Results are always listed for each device type and each method used. The diploma thesis is divided into two parts. The first one analyzes the methods used and the second part states the method results. There is also an overall evaluation of the processed data.

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.

Statistical processing of data of solar radiation in place BUT FME Brno
Nečasová, Klára ; Jaroš, Michal (referee) ; Štětina, Josef (advisor)
This bachelor’s thesis deals with the measurement of solar radiation. The aim of this work is to determine the usefulness of solar energy and solar radiation compared to the oblique and horizontal surface. You are given basic information about solar radiation, the Solar, collectors and sensors. Further work includes measurements and calculations of solar radiation in the course of one year and at the end of the evaluation of measurement results.

Criminality in regions of the Czech Republic in dependence on their economic level
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.
