Risk Management Support System
Kubíček, Jan ; Burget, Radek (referee) ; Kreslíková, Jitka (advisor)
The work provides theoretical base of project management. It describes the current approach to project management as a combination of multiple processes. The process of risk management is described with special care. It also discuss some of the different approaches to risk management. \\ The work suggests new way of handling risk management, that combines risk management and data mining. Data mining approach is also used to mine quantitative risk values. This approach was successfully implemented and tested. Tests showed that this approach is very useful for omitted risk identification. Unfortunately it is also not recommendable for mining quantitative risk values.

Decision Risks Management Methods
Janošík, Petr ; Chudý, Peter (referee) ; Kreslíková, Jitka (advisor)
This thesis deals with the matter of risk managament in IT projects. It explains the importance of risk management in such projects and shows different ways and methods of managing and analyzing the risks. After explaining the basic concepts and the various phases of risk management the text focuses on two methods of risk analysis - the fault tree analysis of event tree analysis. Use of both methods is explained for both quantitative and qualitative analyses. The second half of the work includes the design of an application for the support of risk analysis employing the methods of fault tree analysis and event tree analysis. This is followed by a description of the implementation of the proposed system in a web environment using jQuery, Nette Framework and Dibi.

Využití FT NIR spektroskopie v mlékárenském průmyslu
Kozelková, Monika
The aim of this thesis was to verify and evaluate the possibilities of FT NIR spectroscopy usage in dairy industry. The quantitative calibrations were developed to determinate concentration or physical parameter of sheep and goat milk, ice cream, Olomouc curd-cheese, dry sweet whey, rennet and made curds. Moisture content or dryness (for the nature of the product), fat, protein, lactose etc. as well as some other minority components such as fatty acid or physical properties (pH and titrable acidity) were established as the reference methods of the major components. All samples were measured by the spectrophotometer FT NIR Antaris. The calibration models for each component were created by using Partial least squares (PLS) algorithm and Discriminant analysis. Very good results were obtained for almost all the calibrations where all the correlation coefficients were between 0.858 to 0.999. By using discriminant analysis in order to obtain qualitative evaluation of products we were verifying the ability of FT NIR spectrophotometer to classify analyzed spectrum in to pre-defined classes and thus to determine differences by Olomouc curd-cheese, rennet and courds. The results of this thesis confirm the suitability of FT NIR spectroscopy for quantitative and also qualitative properties of raw materials, intermediate products, as well as final products.

Analyses the divorce rate in the Czech Republic after the year 1989
ŠVARZBERGEROVÁ, Barbora
This diploma thesis analyses the divorce rate in the Czech Republic after the year 1989. The first chapter is devoted to the definition of basic terms. Divorce is the legal dissolution of marriage during the life of spouses. Divorce is the dissolving of the bonds of matrimony between a married couple under the rule of law. Divorce is a social phenomenon reflecting the family stability, there is a transformation of traditional behavioural patterns, moral criteria and economic incentives. Since 1989 till present the divorce rate in the Czech Republic is at a high level. The second chapter of the theoretical part evaluates the development and current situation of divorce rate in our country. It is divided into three subsections: Influencing factors of divorce, causes of divorce and divorce rates in Europe. The aim of this diploma thesis is the evaluation of the development of causes of the divorce in the Czech population, capturing the specifics of the development of divorce in the new socio - economic conditions after 1989. With regard to the objective of the diploma thesis I set three hypotheses. Hypothesis 1: Compared with other EU countries in the Czech Republic the divorce rate persists at a high level after 1989. Hypothesis 2: The divorce rate varies by region in the Czech Republic. It is the highest in regions undergoing restructuring of the economy, with high unemployment rate and social problems. Hypothesis 3: The divorce rate is high in big cities and on the contrary low in traditional, predominantly, rural regions with a stable population. I conducted a quantitative research in the form of data analysis. The main source of the data was the Czech Statistical Office and Eurostat. I have analysed and compared the data which reveal the divorce rate in the Czech Republic and the EU in 2011 and the development of divorce from the year 1989. The data were analysed by correlation and spatial analysis and to compare the data I used the Mann-Whitney and Kruskal-Wallis test. Results show that the divorce rate in the Czech Republic in comparison with other EU countries after 1989 remains at a high level. Crude divorce rate since 1989 is around 3.0 divorces per 1000 inhabitants, which represents one of the highest divorce rates among EU countries. The divorce rate in the Czech Republic was one of the few demographic processes that were the least affected by the economic and social transformations after 1989. According to the results of the data analysis for the year 2011 I have verified, that the divorce rate in the Czech Republic is territorially differentiated, varies in different regions, cities and rural areas. High crude divorce rate is in districts undergoing restructuring of the economy and as a result there is a high rate of unemployment and social problems are emerging. The highest divorce rate in 2011 was in Česká Lípa. Conversely, the lowest crude divorce rate is the less populated districts, with a stable population and a high proportion of religious people. In 2011, the lowest crude divorce rate was in the district of Jihlava. Religion had the most statistically significant effect on the divorce rate. In districts with a higher proportion of religious people the crude divorce rate is lower than in districts with a lower proportion of religious people.

Cesium 137 in wood ecosystem
KAŇKOVÁ, Jaroslava
The first part of thesis is engaged in explanation of some basic concepts regarding an elected topic: radioactivity, isotope, nuclide, halftime, gamaspectrometry etc. In the second part I deal with element cesium and influence of the Chernobyl accident. The final part processes questions of cesium - 137 in wood ecosystem. It is mainly concerned with research and gamaspectrometric measurement of wood substance, bark and samples of soil. In practical part (it is one part of the final part) I made taking of samples (especially soil from the depth 0-5 cm, soil from the depth 5 - 20 cm, wood substance and forest planting) from some localities above all the South Bohemian Region and next their gamaspectrometric measurement (quantitative analysis of cesium - 137 in wood ecosystem) at SÚJB in České Budějovice according to methodology.Measured values of cesium - 137 in samples were relatively low and its impact on the health of our population is in regard to other sources of ionizing radiance insignificant. The supposed hypothesis was herewith confirmed.

Rozbor a algoritmizace metod vhodných pro analýzu rizika a podporu rozhodování
Žůrek, Petr ; Jablonský, Josef (advisor) ; Krajíček, Roman (referee)
Práce popisuje relevantní metody, které se týkají dynamických simulací v oboru kvantifikace rizika, a to takovým způsobem, aby bylo možné na základě nich vytvořit vlastní software pro modelování rizika. Kapitoly v této práci jsou rozděleny na dvě hlavní části. Na začátku je čtenář krátce uveden a seznámen s oborem kvantitativní analýzy rizika a s procesy, které takové analýzy zahrnují, také je v úvodu seznámen s některými termíny a statistickou teorií, bez které se dále v práci neobejdeme. Protože problematika je obsáhlá a cílem práce není její celkový obecný popis, zaměřujeme se pak detailněji na nejpodstatnější části pro dynamické simulace rizika a těmi jsou výběrové metody, generátory náhodných čísel a pravděpodobnostní rozdělení. Práce tedy není určena širokému publiku, ale těm, kteří už obecné základy znají a chtějí pokročit dále a prohloubit své znalosti o dílčích procesech analýzy rizika. První část práce končí kapitolou o způsobu určení pravděpodobnostního rozdělení na základě dostupných dat a v druhé části je na třech případových studiích testována vytvořená aplikace ve srovnání se dvěma konkurenčními tržními produkty.
