Automatické osvojení vzorů s minimální supervizí
Klíč, Radoslav ; Hana, Jiří (advisor) ; Hlaváčová, Jaroslava (referee)
The thesis presents a semi-supervised morphology learner developed by extending Paramor (Monson, 2009), an unsupervised system, to accept easy to obtain manually provided data in the form of inflections with marked morpheme boundary. In addition, a hierarchical clustering framework allowing combination of multiple sources of information was developed as a part of the thesis. The approach was tested on Czech, Slovene, German and Catalan and has shown increased F-measure in comparison with the Paramor baseline.

Černý, Patrik ; Straňák, Pavel (advisor) ; Peterek, Nino (referee)
Title: Voice command for a TV set Author: Patrik Černý Department: Institute of Formal and Applied Linguistics Supervisor: Mgr. Pavel Straňák, Ph.D. Abstract: A goal of this thesis is to create television voice control intended for poeple with speech and movement disorder. This is achieved by interconnecting computer and television. Voice control is based on well-known dynamic time warping algorithm. It has been shown, that due to high and frequent changes in sound intensity the voice control of television is quite a complex task. The word recognition success rate of the final application is not very high, but for the purpose sufficient. Because of application design, program can be easily extended by techniques, that can improve recognition effectivity. Keywords: voice control, word recognition, dynamic time warping, television 1

Pricing and modeling credit risk
Kolman, Marek ; Witzany, Jiří (advisor) ; Kodera, Jan (referee) ; Lukáš, Ladislav (referee)
The thesis covers a wide range of topics from the credit risk modeling with the emphasis put on pricing of the claims subject to the default risk. Starting with a separate general contingent claim pricing framework the key topics are classified into three fundamental parts: firm-value models, reduced-form models, portfolio problems, with a possible finer sub-classification. Every part provides a theoretical discussion, proposal of self-developed methodologies and related applications that are designed so as to be close to the real-world problems. The text also reveals several new findings from various fields of credit risk modeling. In particular, it is shown (i) that the stock option market is a good source of credit information, (ii) how the reduced-form modeling framework can be extended to capture more complicated problems, (iii) that the double t copula together with a self-developed portfolio modeling framework outperforms the classical Gaussian copula approaches. Many other, partial findings are presented in the relevant chapters and some other results are also discussed in the Appendix.

Motive of melancholy in the 16th and in the early 17th century
Bouček, Jan ; Royt, Jan (advisor) ; Nespěšná Hamsíková, Magdaléna (referee)
Motif of melancholy in the 16th and in the early 17th century The author attempts in his presented work to outline in brief basic ways of melancholy motif depiction in fine arts in the 16th and in the early 17th century. Emphasis is primarily placed on personification or allegory of melancholy that is based on the period theoretical considerations. The basis for melancholy perception as a state on the balance of madness and brilliance were laid by classical philosophers like Plato and Aristoteles. Subsequently, these considerations were extended by interconnection of melancholy with astrology in the Middle ages. Thus melancholics get under the influence of the divine Saturn planet. This is where many depictions of so called Saturn children emerge showing allegory of crafts and professions attributed traditionally to melancholics. Frequent depictions of a mythological Saturn-motif swallowing his children are on this basis a symbol of ambivalent nature of melancholics fluctuating between divine brilliance and madness. These ideas were revived by Florentine humanists in particular by the person of Marsilio Ficino in the 15th and 16th century who combined them into a complex theory of melancholy. Thanks to this theory fine arts ceased to be considered in accordance with old tradition a craft and were...

Testaments of Bohemian Noblewomen in the Period from 1650 to 1753. Gender and the Legitimization Strategy of the Nobility within the Early Modern testamentary Discours
SWIDEROVÁ, Kristina
The thesis Testaments of Bohemian Noblewomen in the Period from 1650 to 1753. Gender and the Legitimization Strategy of the Nobility within the Early Modern testamentary Discours is based on the set of accounts left by noblewomen, and tries to find out the role of gender and the meaning of piety within the testamentary field. Using a combination of quantitative and qualitative analysis confronted with prescriptive document´s point of view, it examines the testamentary field at three different levels. First of all, it focuses on the contemporary legal status of women. Secondly it deals with the formal structure and terms of last wills, such as property settlement, which is usually the main reason for testaments being composed. But the emphasis is laid on the testamentary piety, which is perceived among others as a means of the legitimization of the nobility itself, for which the process of the adjustments before death was well suited. The thesis is complemented by a standalone chapter researching codicils, documents supplementing or altering original settlements for the case of death. The comparison of their mutual content with last wills reveals real religious feelings, which are otherwise disguised by the emphasis laid on the formality of the testament{\crq}s text. The main goal of the research is to help in the understanding of creation and manifestation of gender roles in different areas of early modern society´s lifestyles as well as to contribute to the recognition of the changes that, at latest by the beginning of 19th century, led to general secularization of the religious practices.

Latin Hagiography of Early Middle-Ages as a Source for Christianisation of the Central Europe
Izdný, Jakub ; Drška, Václav (advisor) ; Suchánek, Drahomír (referee)
of the paper The goal of the submitted work is to compare extensively the first hagiographical concerning the process of Christianization in the Central Europe. By paralleling these texts across the national rounds and comparing their image with the current state of the historical research the author tries to understand the role of legend in the Christianization and in particular their possible use as a source for this period. The hagiographical image of paganism, the baptism of the state units, of the ruler and the usual way of the institutional spread of the faith with regard to the image of the lower social classes in the process are all examined in the thesis. Further, attention is paid to the coherence of the Central-European area observable in the typology and the content of examined hagiography.

Edge Effects in Voltage-step Transient I. Ohmic Losses in 1D Approximation (revisited)
Wein, Ondřej
Ohmic potential drop between the working and reference electrodes plays an important role in the early stage of the voltage-step transient process. Non-linear effect of the ohmic drop on the transient currents has been calculated for large voltage steps, assuming reversible behavior (negligible surface overpotential) of a redox couple O + ne = R. This report extends an older study by Wein (1991). In particular, it adds a series of analytic approximations and gives more accurate numerical solving.

Patterns in preschool mathematics education
ANTOŠOVÁ, Pavla
Recognising that a sequence of object makes a pattern, explaining why, being able to copy, extend and create a new pattern are early steps towards an appreciation of spatial patterns. Pattern can be described as a systematic arrangement of numbers or shapes which follows a given rule. When children understood what comes next in relationship to what came before, they had no difficulty understanding and making patterns.

Influence of term of winter rapeseed (Brassica napus) desiccation on yield and seed quality
Rajtmajer, Stanislav ; Bečka, David (advisor) ; Petr, Petr (referee)
Rapeseed is the world's third most important oil plant (the second seminal). It is the most cultivation and most important oil plant in Czech Republic. Winter rapeseed reaches about 85% of the harvest area of oilseeds in the country. The desiccation of oilseed crop is sphere of agricultural engineering, which is still worth discussing. The main problems are how to use the product, what dose and which dates to choose to desiccate. The results of this thesis could help to partially clarify this complex issue.
The aim of the thesis is to observe the effect of different terms oilseed rape desiccation by glyphosate on yield and seed quality.
Small-plot experiments to investigate the influence of the term desiccation of winter rapeseed were established in the years 2013/2014 and 2014/2015 on the lands of the experimental station of the Czech Agricultural University, Faculty of Agronomy Food and Natural Resources at the Červený Újezd.
In the first experimental year 2013/2014 was founded five variants in three replications (including undesiccated control). In the year 2014/2015 was founded seven variants in four replicates (including undesiccated controls). In the first experimental year was the first term desiccation 16. 6. 2014, the second year 8. 6. 2015. Subsequent periods of desiccation were a week apart.
The variety of winter rapeseed used for the experiments was a hybrid variety Rohan. The desiccating agent was used Dominator active substance glyphosate. The dose of
4 l / ha + 200 l H2O.
For all samples, both experimental, years yield was determined, the weight of a thousand seeds and oiliness. For desiccated variants were carried out pre-harvest analysis for the determination of solids in pods. Further, all harvested samples taken for laboratory germination test (Determination of germination) ISTA according to the methodology. The results of the experiment sprouting were statistically analyzed using ANOVA analysis of variance. Differences between mean values were evaluated by Tukey test, the computer program SAS at a significance level of p = 0.05.
Effect of desiccation term influences of winter oilseed rape seed quality in terms of weight and thousands of seeds in terms of oil content. Too early desiccation (46 to 39 days before harvest) HTS reduced by 7-17% and the oil content of 2-4% of the overall average. Oiliness of the observed characters minimum interference term desiccation. Desiccation in the optimum date (17 days before harvest) increased oiliness of 1-6%.
Influence term desiccation oilseed rape also greatly influences seed yield.
Too early desiccation (46 to 39 days before harvest) reduced the yield by 11-14%. Undesiccated control in both years achieved the highest yields, increase yield by 5-12%. Desiccation in the optimum date (17 days before harvest) increased the yield of attempts by 5-6%.
The term desiccation of winter rapeseed, also significantly affects the vitality of seeds, where very reduces energy germinating seedlings in the first days. The term desiccation, however, does not affect overall seed germination. Too early desiccation (46 to 39 days before harvest) EK2 decreased by 12-40%, EK3 decreased by 4-24%, 3-4% EK4 and extended MGT of 7-15%. In the first experimental year was the most vital option undesiccated control (EK2 = 50.4% = 91.3% EK3, EK4 = 97.9%). In the second experimental year was the most vital seeds of the optimal term desiccation, (Sixth term, 17 days before harvest) = 68.9% EK2, EK3 = 98.2%, EK4 = 100%. Seed samples of 2014/15 had a higher overall vitality of seeds, than samples from 2013/14, the overall vitality is probably worse given year old and transsilaged seed.
The results of the two-year experiment that term desiccation affects the quality of seeds, the yield of seeds and vitality of seeds. Pre-analysis was determined optimum solids content in siliques desiccated samples to values of 40-50%. Like most technology seems to desiccation in the optimum date (17 days before harvest) and agro technology without desiccated vegetation. As the least appropriate technology seems very early desiccation (46 to 30 days before harvest).
The first scientific hypothesis: Premature desiccation reduces seed yield, oil content and HTS. Yes, the hypothesis was confirmed.
The second scientific hypothesis: Desiccation made in the correct term do not affect the quality of the seeds (oiliness and HTS). Yes, the hypothesis was confirmed.
