Methods for texture analysis in ophthalmologic images
Hanyášová, Lucie ; Szabó, Zoltán (referee) ; Kolář, Radim (advisor)
This thesis is focused on texture analysis methods. The project contains an overview of widely used methods. The main aim of the thesis is to develop a method for texture analysis of retinal images, which will be used for distinction of two patient groups, one with glaucoma eyes and one healthy. It is observed that glaucoma patients don´t have a texture on the eye ground. Preprocessing of the images is found by transfer of the image to different color spaces to achieve the best emphasis of the eye ground texture. Co-occurrence matrix is chosen for texture analysis of this data. The thesis contains detail description of the chosen solutions and feature discussion and the result is a list of features, which can be used for distinction between glaucoma and healthy eyes. The method is implemented in Matlab environment.

Knowledges of the radiology assistants in the field of radiation protection
JIRAŇOVÁ, Anna
The thesis is concerned with knowledge in the area of radiation protection achieved by students of the Radiological assistant program. The theoretical part of my thesis explores the theme of radiation protection. The aim of radiation protection against ionizing radiation is to acquire information which is vital for health protection. The purpose of the thesis was to learn the level of knowledge of students enrolled in combined and full-time forms of the Radiology Assistant studying program in the area of radiation protection at selected schools in the Czech Republic, and subsequently compare their knowledge using methods of descriptive and mathematical statistics.The hypotheses asserted in this thesis are the following: "The level of knowledge of students enrolled in full-time and combined forms of studies will be comparable." "The knowledge of radiology assistants will have a normal distribution." In order to achieve the set aim and verify the hypotheses, it was necessary to create a questionnaire focusing on the given topic and carry out a survey. The questionnaire contained 15 questions. The research file consisted of 57 students of the full-time form of studies and 53 students of the combined form of studies 110 questionnaires from seven universities in the Czech Republic in total.

The role of ICT in the economy of selected European countries
Dvořáková, Dominika ; Doucek, Petr (advisor) ; Veber, Jaromír (referee)
The aim of this thesis is to determine whether the role of ICT in the economies of selected European countries is important on the basis of macroeconomic, statistical indicators and characteristics of selected economies. In the first part the role of ICT in the Czech Republic will be compared with the role of ICT in the neighbouring countries on the basis of share of ICT goods in exports and also on the basis of ICT goods exports and imports. Further with use of WSA method it will be listed, how are ICT used by individuals in these countries. The aim of the second part is to compare advanced economies of selected countries (Germany , France and GB) on the basis of details of economies represented in top 250 ICT firms. The third part will be dealing with the role of ICT in OECD, concretely with ICT services, goods, exports and imports. The outcomes of each chapter will be then compared with characteristic of each economy.

Knowledge of pupils of upper primary schools in the field of protection of population in South Bohemian region
SUKOVÁ, Denisa
Lives of each of us may bring unexpected situations, such as natural disasters, accidents involving release of hazardous substances or extensive traffic accidents. Statutory regulations and organizational measures taken by the state serve to mitigate the consequences of such emergencies. One of the tasks of the state is to protect the society, which also involves protection of population. Citizens themselves can contribute to the mitigation of the consequences of emergencies. Therefore, it is important to educate the citizens in this regard for them to be able react adequately. As part of the training of the population it is important to inculcate children from their early age with the basic rules of protection and help. Thus the issues of protecting people in emergencies are part of framework educational programmes for preschool, elementary as well as secondary education. It is the issues of protection of population that the theoretical part of this thesis deals with. The introduction describes protection of population from a historical perspective. It subsequently describes the current situation not only in the Czech Republic but it also briefly describes the context of the European Union and the political-military organization NATO. The thesis also describes the system of education in the sphere of protection of population at elementary schools. An integral component of the theoretical part is a chapter dealing with the integrated rescue system. The theoretical part is concluded with a chapter on statistical methods. The objective of the thesis was to find out about the level of knowledge of pupils in the 6th and 9th grades in the sphere of protection of population at selected schools in the South Bohemia region and to compare, subsequently, the knowledge of these pupils using the methods of descriptive and mathematical statistics. The following hypothesis was formulated for this thesis: 'Pupils on the 9th grade of elementary schools in the South Bohemia region have significantly better knowledge in the sphere of protection of population than 6th-grade pupils.' To achieve the defined objectives and to test the hypothesis, it was necessary to create a questionnaire focusing on the issue and to carry out a survey. The research group consisted of 100 pupils from 6th-grade classes and 100 pupils from 9th-grade classes at eight elementary schools in the South Bohemia region. The questionnaire submitted to the pupils included 15 questions. The questions in which the pupils showed a lack of knowledge mainly included questions focused on first aid. Evaluation of the questions shows that only 25 % of the pupils surveyed know what the frequency of chest compressions during resuscitation of an adult is and that 54 % of the pupils know how to behave in a situation where somebody is a victim of a high-voltage electric shock. Another problem area is the knowledge of signals. Only 51 % of the respondents know the signal for 'General Warning' and know what to do in the event this signal is sounded. The signal of 'Acoustic Siren Test' is known by only 21 % of them. In contrast, the issues in which pupils showed a good knowledge include, for instance, emergency telephone numbers (85 % of correct answers), integrated rescue system (87 % of correct answers) or evacuation (86 % of correct answers). Overall, the 6th-grade pupils answered all the questions correctly in 52.9 % of cases; it was 58 % in the 9th-grade pupils. The selected hypothesis was tested and confirmed using the methods of descriptive and mathematical statistics. The processed data is presented in the 'Results' chapter and it is subsequently evaluated in the 'Discussion' chapter. The benefit of this thesis is in an obtained image of knowledge in the sphere of protection of population shown by pupils of elementary schools. The outputs of the thesis have been provided to the participating schools.

Time series analysis of precipitations in the selected area
MÁCHA, Vít
Diploma thesis extends my Bachelor´s thesis, which was about methods of time distribution of precipitations and differences in that distribution within a small area. The first part of the paper describes the formation and distribution of precipitation, typical variation of precipitation and some characteristics, revealing and describing the behaviour of rainfall in a given station. Following part describes possible methods of evaluation of time distribution. Statistical methods are presented mainly here. Here described methods and evaluations are subsequently applied in time series of daily precipitations, which has been available for this work for the Jenin creek basin. The analysis is focused on characteristics and evaluation of rainfall between terms 1980 - 1988 and 2005 - 2013. The results show us some differences between terms in rainfall characteristics. However, mostly they are not statistically significant. The work also evaluates differences in rainfall totals between rainfall stations Jenín and Dolní Dvořiště (approximate distance of the stations is 4 km) in 2005 - 2013 term. During the evaluation it comes to differences in rainfall totals. They are highly variable and they don´t have neither constant direction nor size.
