Karela, Jiří ; Mézl, Martin (referee) ; Jiřík, Radovan (advisor)
This master thesis deals with the issue of automatic processing of DCE-MRI data. It describes some important procedures and methods. The work is divided into theoretical part, practical part and conclusion. The theoretical part mainly describes some methods, on the basis of which the practical part was then solved. However, another theory related to the topic is also described here. The practical part then builds on the theory and solves the problem of automatic detection of arterial voxels and the concentration of contrast agent in the arteries. The algorithms are tested on rat brain data obtained from DCE-MRI. The conclusion serves as a summary and evaluation of our results. It also serves as a reflection on the implementation of our methods.

Koloušek, Petr ; Novák, Jakub (advisor) ; Ouředníček, Martin (referee)
New concentrations of job opportunities in the hinterland of Prague Abstract In the past 40-50 years in North America and is currently also in some European regions we can see within the frame of suburbanisation process creation of new centers in the hinterland of the main cities. The development of these nuclei greatly influences the spatial structure of metropolitan areas. The aim of this work is to try to identify new concentrations of job opportunities in Prague hinterland which could be described as indedependent or cutting adrift and in this respect prove certain similarity to the metropolitan regions westward of the Czech Republic. Observation will be mainly applied to the development of the number and structure of job opportunities in the selected villages. These indicators will be helpful to identify the new concentration of jobs in the Prague metropolitan area. Subsequent analysis of commuting to work in selected villages partly answers the question of how the commuting links between elements of the Prague metropolitan area have changed and whether there is a noticeable trend towards the creation of new centers, which would include also non-residential functions, such as significant offer of an employment and services. In the case study of one selected municipality will be subsequently followed up...

Selected Problems in Evidence
Bečvářová, Darina ; Pohl, Tomáš (advisor) ; Macková, Alena (referee)
Various problems which relate to the obligation of assertion and obligation of evidence and corresponding burden of assertion and burden of evidence and activity of a court connected with them are the topic of my diploma thesis. The first part concentrates on the definitions of basic terms, which appear in the field of evidence, for example the evidence as a complex process, the subject of evidence, means of evidence and also key terms as burden of assertion and burden of evidence. The next part of the thesis is focused on the description of the institute, which was introduced to the legal system in 2009 and the aim of which is to make civil procedure faster and more effective. This institute is the concentration of the procedure, principle of which is to bring about the state of termination of facts and evidence, which means that parties of the civil procedure are allowed to present facts important for the decision of the court and evidence connected with them only until a certain moment, if they present them later, they will not be relevant for the court. In the present, the parties are obligated to fulfill these obligations until the end of the preliminary procedure happens, respectively until the end of the first procedure in front of the court happens or when the parties are given an additional...

Trends of ambient ozone in the Northern hemisphere
Bučková, Nicole ; Hůnová, Iva (advisor) ; Hovorka, Jan (referee)
The development of ground-level ozone concentrations is currently hotly debated topic. Ozone itself is highly toxic and has strong oxidizing effects. Ozone has negative impact on human health, but also on vegetation. In addition ozone is one of the most important greenhouse gases causing the greenhouse effect. The Council of Europe decided to limit its increasing tendency by the release of Directive 2002/3/EC. Limits that are set in this Directive are binding for all Member States without exception and breach of these limits is enforceable by law. However as a result of increased anthropogenic activities, particularly increased consumption of fossil fuels and the development of industrialization, those limits are very often breached. Especially in summer when is solar radiation is most intense. This suggests that the highest ozone concentrations are in southern Europe. North Europe has problems with intercontinental transport of ozone. Concentration of ozone is dependent on many factors - the weather conditions, the geography but also the impact from human activity. This paper describes the development of ground-level ozone concentrations in various regions in Europe and North America. In writing this work, I come out mainly from foreign studies that address this topic. Keywords: ozone,...

Financial Geography - An Application of Selected Concepts in Terms of the Czech Republic
Bečicová, Ilona ; Blažek, Jiří (advisor) ; Feřtrová, Marie (referee)
FINANCIAL GEOGRAPHY - AN APPLICATION OF SELECTED CONCEPTS IN TERMS OF THE CZECH REPUBLIC Abstract The aim of the thesis is to analyse the main trends of banking system in Czech Republic after 1989. It is primarily an analysis of centralised banking system, on the basis of which the potential regional impacts according to theory of regional segmentation of fiancial markets are tested. Based on the analysis of changes in the distribution of bank headquarters and the analysis of employment in financial sector it is clear, that in terms of the Czech Republic a highly concentrated banking system occured, which is moreover under the strong inluence of foreign capital. The study focused on testing the regional impacts of a centralized system through interviews with business owners in the peripheral region has not proved allegation of discrimination of entrepreneurs in such manner as we would expect according to the theory of regional segmentation of financial markets. However the study showed some problems with providing guarantees for bank loans in the periphery.

Use of unpublished data on total suspended particles in the CR measured during the 1970s and 1980s as an invaluable information and comparative material to current measurements
Pavlovicová, Martina ; Hůnová, Iva (advisor) ; Stráník, Vojtěch (referee)
Air pollution of atmospheric aerosol is one of the biggest problems across Europe nowadays. The atmospheric aerosol is natural part of Earth's atmosphere that significantly participates in important atmospheric activities. The late 1960s of 20 century, however, air pollution by anthropogenic activities is gets into the minds, which caused the first aerosol load associated with the development of mining activities and industry. The first cases of increased incidence of allergies and respiratory diseases in children were discovered. At that time, the first arrangements to improve the unfavorable situation and also the first measurements of concentration of particulate matter in ČSSR were initiated. During 1970s and 1980s of the last century, concentration of particulate matter was measured in more than 100 stations. Particulate matter was measured as total suspended particulates (TSP) in the air. This bachelor thesis describes four areas of interest in ČSSR, which were affected by particulate matter pollution during mentioned years the most. They are Ostrava-Karviná region, North Bohemia, Brno agglomeration and Hradec Králové and Pardubice region. In my bachelor thesis I dealt with the transfer values of particulate matter concentrations to values of PM10 and PM2,5 concentrations. The main goal of...

Mental concentration of florball players
Novotný, Tomáš ; Harsa, Pavel (advisor) ; Dragounová, Zuzana (referee)
- english Abstract The aim of this bachelor thesis is to highlight the importance of mental concentration of floorball players during training and before a match and to highlight the importance of concentration during sports preparation. In the theoretical part of the thesis, based on the available literature sources, the thesis first discusses the topic of the sport and describes floorball in general - e.g. its history, rules, or important players. It focuses in detail on the mental concentration of players, which is related to concentration, fatigue and depression, for example, and explains what influences all of them, why they are important in sport, and which factors can affect it negatively. The practical part is based on a questionnaire survey among selected respondents. The results of the survey will be used to evaluate the influence of the players' mental concentration on their performance. Keywords sport, floorball, concentration, mental concentration, psyche, mental states, mental states, attention, attention disorders, fatigue, conflict, stress, motivation short and long term memory, survey, factors

Změny v odvětví pivovarnictví a jejich ekonomické dopady na malé české pivovary
Krestýnová, Martina
The thesis is focused on the brewing industry in the Czech Republic and changes within it which influenced the development of small Czech breweries. An analysis of the industry is performed using the Porter's Five Forces model focusing on the five competitive forces represented by the threat of new entrants, the bargaining power of suppliers, the bargaining power of customers, substitute products or services, and established rivals. Market concentration is also analyzed given the changes in the brewing industry. Changes in consumer demand and their influence on the brewing industry are examined subsequently. In particular, the change of consumer preferences leading to an increased consumption of stronger beers or aspects of beer selection are analyzed. Based on the findings, the impacts of these changes on small Czech breweries are described. In the next part of the thesis, economic results of selected breweries are compared using the indicators of value added margins, return on assets, return on equity and return on sales.

Hodnocení kvality ejakulátu u ovčáckých plemen psů
Leciánová, Tereza
This diploma thesis deals with the quality of ejaculate of shepherd dog breeds. In the first part we will classify shephed dogs within the FCI organization and we will approach the breeds that we assess in this work. We will describe the anatomical and physiological characteristics of the reproductive organ of male dog, its ejaculate, ejaculation, semen and their development. We will also learn about the possibilities of dog ejaculate collection. In the main section we will deal with the evaluation of the ejaculate and we will focus on the macroscopic and microscopic examination of fresh ejaculate. In the course of the work, 100 ejaculates from 28 dogs belonging to I. FCI group will be evaluated, each dog will be taken twice to four times and one shot will be made from each sampling. The dogs will be divided into groups according to age, breed, stabling and feeding, and the examined parameters of the quality of the ejaculate will be discussed and compared. In terms of the monitored indicators, a highly statistically significant effect (P is less than or equal 0.01) of the order of collection on the volume of ejaculate obtained will be demonstrated. A statistically significant difference (P is less than or equal 0.05) between the first and the second sampling will be found in the evaluation of the effect of the order of collection during one day. The second volume will be found to be lower than the first one. It will be also shown that this value is affected by the age of the dog. According to our research, breed type and age of the dog causes a statistically significant difference (P is less than or equal 0,05) for sperm activity. The order of collection and stabling have a lesser influence on this indicator and the feed represents a negligible factor. Concerning the sperm concentration in the ejaculate, we will demonstrate a statistically significant difference (P is less than or equal 0.01) between the age groups of the dogs and the type of their accommodation. We will find a statistically significant difference (P is less than or equal 0.05) in the order of sampling. The factors of breed type and feed will have minimal influence in this case. We will not prove a statistical difference in the influence of the studied factors on color and odor, and we will be able to assert that these factors have negligible influence on these values. As for the qualitative sperm indicators, we will focus on the percentage of altered heads, connecting parts, flagella, degenerate and immature sperm. Concerning the values, we will conclude that the breed type, the age and, in the case of immature sperm, the order of collection have the most important influence on these parameters.
