Effect of admixtures on the properties of metakaolin geopolymer
Halasová, Kristýna ; Vyšvařil, Martin (referee) ; Rovnaník, Pavel (advisor)
Geopolymers are amorphous to semi-crystalline aluminosilicate polymers which are formed from inorganic polycondensation reaction of a solid aluminosilicate precursor with an alkaline sodium hydroxide or silicate. The resulting materials exhibit high durability, resistance to aggressive environments, high temperature resistance and many other properties that make them have received much attention in recent years, not only in construction. This thesis describes the influence of additives commonly used in concrete and mortar (water reducing, superplasticizer, air-entraining, foamer and defoamer, anti-shrinkage, stabilization) on the behavior of metakaolin in geopolymer fresh and hardened state. It describes metakaolin geopolymer effect on rheological properties of fresh mixtures, compressive strength and flexural strength after 28 days and a density in the fresh and hardened state.

Eucaryotic Genomes Comparison
Puterová, Janka ; Vogel, Ivan (referee) ; Martínek, Tomáš (advisor)
Main motive of this master thesis was the need of good bioinformatics tools for genome comparison and improvement of one of the existing tools - RepeatExplorer. This work offers an overview of transposable elements in DNA, existing tools for identification and analysis of repetitions in sequenced genomes, summary of currently used genome sequencing methods. This work describes shortcomings of RepeatExplorer tool with focus on comparative analysis of genomes. Two solutions to remove these problems were designed and implemented. The first solution is designed for comparing pairs of genomes. The principle of this solution is based on comparison of similarity of distribution of contigs coverages using Kolmogorov-Smirnov test, thanks to which we are able to determine different parts in the genomes.The second solution, which is used to compare multiple genomes, is based on the method of mapping reads from compared genomes to the reference genome contigs and provides contigs coverage graphs, by which we are able to determine the variability of the repeats.Their functionality was verified on real NGS data of organism Silene latifolia.

The Case of Law in the Field of Value Added Tax and its Impact on Legislation
Havlíková, Barbora ; Toman, Petr (advisor) ; Zídková, Hana (referee)
Harmonization of tax systems of the European Union member states has been going on since 1950s. This trend is followed to this day in order to achieve one of the primary objectives of the European Union, single domestic market. The harmonization of tax systems allows free movement of capital, goods, and services. Value added tax is harmonized through the EU Directives that have unified tax object, tax base and partly tax rates. The Court of Justice of the European Union also plays a vital role in the harmonization, because the European case law complements the interpretation of the directives and creates a comprehensive impact throughout the harmonization. This thesis analyses the judgments of the Court of Justice of the European Union, which have been implemented in the VAT Act, and examines at the same time impact of the implementation. The first implementation took place in the amendment of the VAT Act in 2006. The biggest changes occurred in the amendment of the VAT Act in 2012 and it was mainly in the realm of the conditions for exemption from VAT without deduction and the possibility of claiming a deduction. Finally, time frame of the implementation was also researched, judging from the outcomes of the research, one can say that the Czech Republic responds quite flexibly to the publication of the European case of law and the implementation takes place shortly following verdict of The Court of Justice of the European Union.

Finanční a technická analýza zemědělských komodit
Foglar, Martin ; Fičura, Milan (advisor) ; Veselá, Jitka (referee)
Cílem zpracované diplomové práce je poskytnout čtenáři informace o světovém trhu zemědělských komodit, přiblížit dění na trzích pěti vybraných zemědělských komodit v posledních letech a analyzovat možnosti použití různých strategií na datech za několik desetiletí do současnosti. Teoretickým základem pro objasnění významu trhu zemědělských komodit je analýza zpráv mezinárodních institucí. Pro praktickou část jsem nejprve zvolil Nejprve strategii Larryho Williamse. Zabýval jsem se v ní použitím indikátorů Larryho Williamse, který je považován za jednoho z nejlepších komoditních obchodníků na světě, jehož myšlení je zaměřováno především na fundamentální analýzu. Následně jsem se pokusil aplikovat systém Woodies, jehož autorem je Ken Wood, jako analýzu technického rázu, která je obyčejně používána pro intradenní obchodování. Jako poslední jsem zvolil konzervativnější strategii spreadů, která je i doporučována pro trh zemědělských komodit - sice nedává možnost značných výdělků, ale zároveň je zde omezeno riziko ztráty. Práce má přidanou hodnotu nejen ve volbě netradičních typů strategií, ale i jejich variací.

Morphology development in children at family risk for dyslexia - contribution to study prerequisites for the development of literacy skills in children at risk for dyslexia
Kučerová, Tereza ; Kucharská, Anna (advisor) ; Špačková, Klára (referee)
A b s t r a c t This thesis is a part of the project concerning risk factors of manifestation of specific learning disabilities in children at risk of dyslexia. Specifically, it deals with the development of morphology in children with family history of specific learning disabilities. Children in preschool and early school age have been repeatedly within three years tested with a diagnostic tool called Test of morphological awareness based on the Test of language (Žlab, 1992). The aim of the study was to map the development of several sub-areas of morphological skills (gender forms, plural nouns, past tense and 3rd person singular verb, adjectives derivation and grammatical agreement). Several issues were concerned. First, whether the development of children in this age group is still ongoing and so if the performance is improving. Second, whether there are differences in the development of children from an intact group (with normal speech development) and a risk group (children from families where at least one parent has suffered from specific learning disabilities). Third, whether is the development influenced by intelligence or sex. Performance of children was also assessed qualitatively with respect to specific language features included in the monitored areas of morphology. The conclusions of each...

The geographical drought – a different view of the issue and its application in practice
Kolejka, Jaromír ; Batelková, Kateřina ; Ruda, A.
Czech Republic, the land locked Central-European country faces the risk of drought in the last two decades. This problem is being studied by number of academic and applied institutes. We have focused on the so called geographical drought caused by an integral impact of representative factors of all natural landscape components and human land utilizing. Using GIS technology, we have carried out an exemplar research ignited by the hot wave and the precipitation deficit in the 2013 summer. Using detail natural component maps and land use data at the resolution 1:50 000, five territorial classes of drought risk were distinguished. Some of the most endangered areas cover large territory in the most fertile agricultural land in Southern Moravia. The artificial irrigation has to be planned and constructed on large plots primarirly to prevent harvest loses after hot wave has started.

Overlapping domain decomposition preconditioners for elliptic and parabolic problems in primal and mixed form
Blaheta, Radim
In this lecture, we concern the numerical solution of PDE problems and describe overlapping domain decomposition, which provides a tool for the construction of parallelizable Schwarz type iterative solvers and preconditioners. The idea of using overlapping domain decomposition goes back to Schwarz alternating method from 1870, see [1]. The analysis of this alternating iterative method was evolved by great mathematicians, see e.g. S.L. Sobolev (1936), R. Courant and D. Hilbert (1937), S.G. Michlin (1951), M. Práger (1958), I. Babuška (1958), F.E. Browder (1958). The use of overlapping domain decomposition for parallel computations started in the late eighties in the work of M. Dryja and O. Widlund [4], P.L. Lions [5, 6], S. Nepomnyaschikh [7] and others and continue up to the present days. The origin of the alternating Schwarz method is nicely described in [8].

Empirický bayesovský přístup v mikromodelech pro výpočet rizika rezerv
Fedorčáková, Claudia ; Zimmermann, Pavel (advisor) ; Bílková, Diana (referee)
The traditional reserve estimation by an insurance company is based on the aggregated data. However, new trend is to utilize all the information available and analyse each claim separately. This way the application of claims specific features, such as non-proportional reinsurance or policy limits, is possible. The aim of this thesis is to construct the reserving model based on the individual claims. Following the recent legislative changes, the reserve risk has been redefined from ultimate claim horizon to a one-year risk horizon. Hence, the next task is to setup simulation model to calculate one year horizon reserve risk by updating the estimates based on new observations collected over one year. This is a typical task for Bayesian approach, therefore the model components are estimated using the tools of Bayesian statistics.
