Tissue characterisation in spectral CT data
Poláková, Veronika ; Jan, Jiří (referee) ; Jakubíček, Roman (advisor)
This bachelor thesis deals with tissue characterisation in virtual monoenergetic images (VMI). Firstly, literature survey presents spectral CT which allows reconstructing VMI. Secondly, statistical evaluation of tissue CT numbers was made for all energies of VMI which were reconstructed. It was found that with growing energy of VMI CT number increases or decreases with different steepness depending on a type of tissue. As a consequence, the suitable VMI offer better contrast resolution between selected pairs of tissues, which enables better tissue segmentation and classification in these images.

Mathematical model of defect frequency on selected stations of engine assembly line
Ministr, Martin ; Tlášek, Karel (referee) ; Maroš, Bohumil (advisor)
The quality and the defectiveness of production are important factors in all sectors of engineering industry. On their improve there are a lot of effective tools, descriptive statistics is one of them. Descriptive statistic has many applicable tools but this work primarily focuses on desription of production using time series plot, testing of statistical hypothesis, testing of mutual dependencies of particular defects and control diagrams drawing. It is about a project that connects practice with theory.

Measurement of Human Hand Geometric Parameters
Vanžurová, Anna ; Hrabec, Pavel (referee) ; Štarha, Pavel (advisor)
In practice, there is no easy way to obtain the size of the surface of a human hand. Therefore, this work deals with the search for a mathematical model determining the approximate surface of the hand. This model uses the basic geometric parameters of the hand obtained from her photograph. Since it is necessary to obtain parameters from the image, compare the mathematical model with reality and verify its accuracy in terms of statistics, the work includes the theory of digitization of image information, 3D scanning and statistics.

nalysis of Indebtedness of Students
FIALA, Michal
This work pursues the matter of indebtedness of young people. It focuses mainly on analysing the answers given by the young people in a survey which was conducted between students. Based on the results given by the survey we estimate indicators such as an income, expenditure and how many youngsters already have an experience with loans. The answers from the survey are also used for descriptive statistics or evaluation of hypothesis. For this the chi-square test is used. From this test we are able to say whether the men are more likely to be in debt or not or if there is some connection between the loans and the education. The aim is also to compare the supply of loans for the young people which are offered either by the banks or the non-bank institutions. The information for the comparison is based on the internet sources.

Descriptive statistics in R with application on real data
Pirohová, Eva ; Bašta, Milan (advisor) ; Šulc, Zdeněk (referee)
The aim of this thesis is to introduce the statistical software R, its use in descriptive statistics and to explain the principle of entering commands and functions in R. In the theoretical part of the thesis the user will be given the basic information about descriptive statistics and the key principles of R software. An important part of the thesis is an illustration of functions and codes which are to be entered into a script or a command window. The practical part represents the way of applying descriptive statistics on real data by using functions and codes in R, including the corresponding types of graphs. There is always an explanation following the example. This thesis contains all the important information which those who start with basic statistical analysis and R software should know. Despite the fact that working with R may be rather complicated at the beginning, this thesis is written in such a way so that it can be read by a beginner in R and statistical analysis.
