Analysis of Social Media Content Discussing Czech Mobile Operators
Pavlů, Jan ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
The main topic of this thesis is sentiment analysis of posts obtained from a social networks. The posts are about czech mobile network operators. The essential part of implemented system is also data visualization. The sentiment analysis is done using machine learning techniques. Downloaded posts are cleaned, lemmatized and transformed to feature vectors. Stochastic Gradient Descent algorithm is used for classification. Analyzed data are visualized in charts and as the list of posts. The system provides tools for text categorization. The accuracy, precision, recall and F1 score of sentiment analysis is about 75%. The accuracy of post categorization is high (about 80%), but precision, recall and F1 score are low (about 30%). This is the reason why post categorization isn't automatically done. The benefit of the system it that it automatically collects data from different sources, analysis them and displays them. It also provides tools for manual change of sentiment/categories which can lead to better system characteristics with some help of users.

Interfaces for Faceted Search in Indexed Wikipedia
Cilip, Peter ; Otrusina, Lubomír (referee) ; Smrž, Pavel (advisor)
Main aim of this thesis is to study existing systems of faceted search and to design own system based on faceted search in the index of Wikipedia. In this thesis we can meet with existing solutions of faceted search. From mistakes and failures of existing solutions was designed our own system, that is output of this thesis. Designed system is described in way of design and implementation. Product of thesis is application and graphical interface. Application interface can be integrated into existing informational system, where it can be used as multidimensional filter. Graphical interface provides option how can application interface be used in real system. System was created focusing on usefullness and simplicity, for using in existing information systems.

Transfer prices: meaning and definition from constitutional law perspective
Hájek, Jan ; Marková, Hana (advisor) ; Mrkývka, Petr (referee) ; Sejkora, Tomáš (referee)
140 Transfer prices: meaning and definition from constitutional law perspective Abstract The thesis deals with the problem of the definition of transfer prices in the substantive tax law, which in general terms it puts in connection with the constitutional requirements arising from the theory of law and normative formation. Thus, the basic grounds for the regulation of transfer pricing in Act No. 586/1992 Coll., on Income Taxes and the OECD Model Double Tax Convention as primary sources of law, legislative definition of this area in domestic and international tax law are defined. These are further elaborated into the detailed level of the methodology of determining the transfer price, which follows from the Instruction of the General Tax Directorate D - 34 and the OECD Transfer Pricing Guideline, and are also subjected to a critical examination in terms of their legal bindingness, position in the legal system, but also from the perspective of the rule of law maxim in the sense of the clarity of the law and its predictability. On the basis of the submitted argumentation, it is concluded that none of the above-mentioned documents defining the procedure by which the transfer price is to be determined is a binding source of law a limine and will always constitute only a non-binding instruction or guide to its...

After fell of the communist regime gradually emerged and crystalized a pluralist party system. First part of this thesis is focused on theory of democratic transition and consolidation subsequently there is space dedicated to the theory of political parties and party systems. Second part is single case study dedicated to description of the Czechoslovak transition with regard to theoretical concepts of the theory of democratic transition and consolidation and through content analysis of relevant laws and constitutional laws are observed emergence and subsequent forming of pluralist party system at the federal level of the Czechoslovak Federative Republic.

Selected aspects of intensively cultured European whitefish (Coregonus maraena, Bloch) and peled (Coregonus peled, Gmelin)
ŠEBESTA, Roman
Maraena whitefish and peled are considered to be economically important fish species. This Ph.D. thesis deals with testing of selected aspects which show potential for improvement of quality and effectivity of larvae and juveniles of both fish species in recirculating aquaculture systems. The whole Ph.D. thesis includes 9 chapters described in 125 pages. In chapters 2-8, there are described the individual factors which can influence quality of intensive rearing of mentioned fish species. The effect of light intensity and tank wall colour on growth and survival of peled larvae is tested in chapter 2. The effect of different temperature on growth and survival of maraena whitefish larvae is presented in chapter 3. The effect of various stocking density on growth and survival of maraena whitefish larvae is given in chapter 4. The influence of different feeding strategy on survival, growth, and intestine and liver development of maraena whitefish larvae is being shown in chapter 5. The effect of various weaning time and co-feeding duration on growth and survival of peled larvae is described in chapter 6. The effect of variable water oxygen saturation on growth and haematological profile of peled juveniles is shown in chapter 7. The prevalence of deformities in intensively reared peled and comparative morphometry in intensively reared fish compared to pond-reared fish is described in chapter 8. Ph.D. thesis contains important advices which can be used in fishery practise and at the same time they can prevent from elevated fish mortality.
