Condition dependence of secondary ornamentation and mate choice in Grey Partridges
Gabrielová, Barbora ; Albrecht, Tomáš (advisor) ; Sedláček, Ondřej (referee)
This study focuses on relationships between individual condition, measures of ornament expression and mate choice in the Grey Partridge (Perdix perdix). It is based on the correlative data as well as results of manipulative experiments. I found positive correlation between the size of melanin- and carotenoid-based ornaments in partridges. The size and the redness of the carotenoid skin patch, and the size of the melanin-based feather ornamentation were associated with several measures of immunity and overall body condition (complement activity, ratio of immature erythrocytes, heterophil/leucocyte ratio, response to novel antigen). Furthermore, data from natural populations indicate that the expression of carotenoid-based ornamentation is associated with sexual attractiveness (measured as the ability to obtain a social mate) in partridges. Data from captive individuals indicate that carotenoid supplementation improves the redness of carotenoid-based ornament, while the stimulation of the immune system under increasing concentrations of supplemented carotenoids has no measurable effect on condition and physiological state. This seems to contradict predictions of the 'Carotenoid maintenance hypothesis'. Overall, results better understanding the role of carotenoid and melanin-based ornamentation in signaling...

Cloud computing: The analysis of possible solutions
Bednář, Josef ; Pour, Jan (advisor) ; Šedivá, Zuzana (referee)
The aim of the bachelor thesis on "Cloud computing: The analysis of possible solutions " is primarily a technical presentation of the current phenomenon of cloud computing, then assembled with the comparising scenario assessment of the performance of applications 365 Office and Google Apps, and to evaluate its suitability for the deployment in mid-sized companies. To fulfill the above objective work, I gave the first study of the entire cloud issue - its definition, methods of securing and study of legislative frameworks and standards that relate to the cloud issue. After studying theoretical perspective on the cloud, I focused on software products 365 Office and Google Apps. To final section, a comparison of selected applications, I came up with study materials and the creation of test scenarios. In the first part of the thesis I focus on the description of cloud computing from the perspective of the individual models, which are put into operation. The following section describes the cloud security, the benefits which it can deliver to company and on the other side, where they can see the downside. Another framework is legislation, as it directly af-fects the security and establishes rules to be observed. In the optimal state legislation pro-vides safeguards and protects both providers and users. Right in work is therefore given the diversity of law, affecting cloud computing in different countries and also on what to watch out for contracting with providers. The second part presents the characteristics of products, Office 365 and Google Apps, then describes the introduction and implementation of the configuration of individu-al products, which are the necessary steps for the mutual comparison. The very creation of the comparison of 365 Office product and Google Apps prod-uct was made by mine in advance proposed test scenario. In the final part is the result of a comprehensive evaluation and comparison accord-ing to established criteria and their weights is chosen recommended more suitable product. Thesis highlights the importance of understanding the cloud, among other because of careful choice of model of cloud, and also choice of a provider. The outcome of the test scenarios work gives an overview of the functionality and product reviews 365 Office and Google Apps. Based on the comparison of results and supporting information for each product, I recommend the more appropriate one. The work is not only beneficial for those interested in understanding the cloud, but also for companies contemplating about the de-ployment model Software and services to their business.

Influence of Selected Factors on Students' Mathematical Literacy in Central European Countries : Secondary Analysis of PISA 2003 Data
Voňková, Hana ; Byčkovský, Petr (advisor) ; Půlpán, Zdeněk (referee) ; Boschek, Petr (referee)
In this work we investigate the impact of selected personal, family and school characteristics on the level of mathematical ability of fifteen year old pupils from 6 countries of the Central Europe (Czech Republic, Hungary, Germany, Poland, Austria and Slovakia) and from countries with excellent results in mathematics (Finland, Hong Kong and the Netherlands). Then we compare the impact of the factors in the individual countries. Much can be concluded from this analysis. The type of school attended by the pupil has a great impact. The maximal difference between type of schools can come up to 40 percentage points in some countries (CR, Hungary, Poland and Slovakia). We do not discuss this factor in Finland and Poland, where all fifteen year olds attend one type of school. The results in these countries are therefore determined differently. As for other basic characteristics of the school, the size matters in some countries (Hong Kong and the Netherlands) and has always a positive effect. The urbanization level of the place of the school (the size of the village or city) is also positively correlated with the mathematics result. Here the Netherlands and Germany form an exception. The status of the school (public vs. private), lack of well-educated teachers, equipment of the school and enthousiasm of the...

Th1/Th2 cytokine gene polymorphisms in patients with idiopathic pulmonary fibrosis
Vašáková, Martina ; Stříž, Ilja (advisor) ; Posová, Helena (referee) ; Šedivá, Anna (referee)
Objectives: Idiopathic pulmonary fibrosis (IPF) is a serious disease characterized with progressive scarring of the lungs in which the genetic background is supposed. The aim of our study was to investigate Th1/Th2 cytokine gene polymorphisms to evaluate their possible influence on IPF development. Then we have correlated selected polymorphisms of IL-1, IL-4 and IL-12 groups ( the selection was based on our previous results) with clinical parameters and high resolution computed tomography (HRCT) as a markers of disease stage and progression. Methods: We investigated 30 patients with IPF and 103 healthy volunteers for the cytokines polymorphisms of the IL-1 alpha, IL-1 beta, IL-1R, IL-1RA, IL-2, IL-4, IL-6, IL-10, IL-12, TNF alpha, IFN gamma, TGF beta, IL-1 beta, IL-2, IL-4 and IL-4RA genes. The PCR-SSP method was used for measurement. Then the correlations of vital capacity(VC) and diffusing capacity for carbon monoxide(DLCO), bronchoalveolar lavage (BAL) fluid cell counts and high resolution computed tomography (HRCT) alveolar and interstitial scores with different genotypes of groups of IL-1, IL-4, and IL-12 cytokines and their receptor antagonists. The HRCT results were evaluated by an experienced viewer using the interstitial and alveolar score scales, which were based on the IPF HRCT description system...

Monitorování serverů zapojených do výpočetního GRIDu
Burdík, Michal ; Chudoba, Jiří (advisor) ; Yaghob, Jakub (referee)
The goal of the work was to study of public and specialized software tools which can be used for monitoring of computing farms. Nagios and Ganglia were chosen as suitable products for Golias farm monitoring in Institute of Physics, Academy of Sciences, Czech Republic. Ganglia was installed from scratch and Nagios was recon gured. We decided to extend Nagios functionality with additional components. As the extensions which ful l our demands do not exist, we decided to develop and implement new ones. In this work, this group of components was named NagiosTools. These components are designed generally and they can be used for other similar computing environments. During work monitoring data from Golias farm were collected.

Modely výpočetní inteligence pro hydrologické predikce
Paščenko, Petr ; Petříčková, Zuzana (referee) ; Neruda, Roman (advisor)
The thesis deals with the application of computational artificial intelligence models on hydrological predictions. The short term rainfall-runoff prediction problem is studied on the real data of physical time seriesmeasured in the watershed of river Plučnice. A brief statistical study including correlation and regression analyses is performed. The high level of variance and noise is concluded. The evolution of the proper input filter providing an input set for the neural network is performed. In the main part of the thesis several neural network models based on multilayer perceptron, RBF units, and neuroevoution are constructed together with two neural ensembles inspired by the bagging method. The models are tested on the three subsequent years summer data. The greater generalization ability of multilayer perceptron architectures is concluded. The resulting multilayer perceptron models are able to reduce the mean squared error of the prediction by 15% compared to the prediction by the previous value.

Projection of police discourse into the regional-media texts based on example of Beroun area
Rosí, Luboš ; Trampota, Tomáš (referee) ; Křeček, Jan (advisor)
The diploma thesis ("Projection of Police Discourse into Releases of Regional Media Exemplified on Beroun Region") deals with the local journalists' approach to their source texts of police discourse when elaborating press releases. Within the introduction the thesis submits the explication of the latest stance to term "discourse", including adumbration of the possible problematic passages. Furthermore the thesis brings up detailed characteristics of both police and media jargon and successively allege their partial analyses such as the comparison of the releases' preambles, usage of quotations, sub-titles, passive forms, or the comparison of analyzed communication areas regarded from the authors' labour with sources' point of view. The main issue is observed by means of four detailed analyses of projection, substitution or eventually creation of police discourse in the media releases. Besides mentioned the thesis also tries to prove the correlation between the media size and the rate of police discourse projection in it's output. Conceived in limited field, a piece of thesis is likewise discursive and critically discursive analysis of police discourse.

Comparation of Software Process Maturity Level of Enterprises in Czech Republic
Borský, Miroslav ; Král, Josef (referee) ; Richta, Karel (advisor)
There are many software developing companies in the Czech republic. However the quality of their software processes is almost unknown. The thesis provides insight into the maturity level of the software processes and finds a relation between the maturity level and a size of the company. The survey of the maturity level was performed at fifteen companies developing the financial software. Additionally, a bank and a foreign company teams were chosen for a comparison. Collected data were represented in a graphical format and a description was provided. A correlation between a size of a company and the maturity level rating have been detected at five out of eighteen process areas and at two out of four process area groups. A possible explanation for those correlations was offered.

Monitoring of water use, druought and yield impacts of winter wheat using imaginery from satellites
Jurečka, František ; Anderson, M. ; Hlavinka, Petr ; Semerádová, Daniela ; Trnka, Miroslav ; Hain, C. ; Gao, F. ; Yang, Y. ; Žalud, Zdeněk
Remote sensing can be very useful tool for drought monitoring, providing valuable information about yield-limiting moisture conditions and crop response under current climate conditions. In this study the Atmosphere-land Exchange Inverse (ALEXI) model was used. The ALEXI model uses the morning surface temperature (LST) rise and provides information on the surface moisture status. In this paper correlations between yields and satellite indicators of crop water use or evapotranspiration (ET) were studied for the period 2002-2014. Correlations were studied for winter wheat at district scale in Vysocina, Jihomoravsky and Olomoucky regions since winter wheat is one of the traditional and most important crops grown in these regions. The Evaporative Stress Index (ESI) was used for these correlations as an ET-based index. Time series of Pearson correlation coefficient (r) computed between ESI and winter wheat yields at district scale were analysed. Strongest correlations are associated with districts within the Southern Moravian lowlands in Jihomoravsky and Olomoucky region, where frequency of occurrence of severe drought was highest over the period of record. Severe drought resulted in significant yield impacts, particularly in years 2003 and 2012. Correlations tend to be lower over the highlands districts of Vysocina and surroundings. In these districts, yields are more temperature than moisture limited and were more stable over the period of record.
