Cross-border mergers
Hubáčková, Marie ; Pelák, Jiří (advisor) ; Mezerová, Jana (referee)
This thesis deals with the topic of cross-border mergers in the Czech republic. In the introductory part, the expressions like merger, cross-border merger are explained and reasons and possible obstacles of the merger (cross-border mergers) execution described. In the following chapter, I mention the possibilities of cross-border mergers in the Czech republic up to now. The thesis also handles the influence of the Directive on cross-border mergers of limited lability companies and the Verdict of the European Court of Justice in the matter of sp. zn. C-411/03 SEVIC Systems AG on the final version of the new legal Act on Transformation of Companies and Cooperatives. In the next chapter, I deal with the legal, accounting and taxation aspects of the cross-border mergers under the current conditions and according to czech legislation. I also included a chapter about the control of mergers of competitors. The last chapter mentions a concrete example of the real first cross-border merger in the Czech republic.

Tax aspects of the emission allowances trading
Knupp, Aleš ; Pavel, Jan (advisor) ; Pavel, Jan (referee)
This study deals with questions regarding Carbon Dioxide allowances market. By giving an explanation of the most important terms and core coherences of the EU ETS system, it endeavours to provide thematic organized preview of the allowances as a whole. The work stands on several pillars which are essential for existence of the allowances market. I mainly talk about national legislation giving basic law framework, then National allocation plan and, on the international level, I refer to the Kyoto protocol and global connection of previously separated market systems on a worldwide scale. The work's goal is to expand on the theme of emission trading and draw out possible impacts on the individual emitents and the whole economy. The first chapter deals with allowances as a matter of czech legislation and financial accounting. In the following text I discuss a trading emission scheme and give readers a vivid example for practical illustration. The Last part is devoted to the future of trading and, in particular, to the implementation of the auction system which allows the producers to buy the allowances themselves.

Tracking of axonal bundles in diffusion MRI brain images
Piskořová, Zuzana ; Vojtíšek, Lubomír (referee) ; Labounek, René (advisor)
The aim of this thesis is to design tracking algorithm which will be able to track white matter bundles in diffusion MRI data, this problem is called tractography. Tractography is feasible because specific profile of diffusion appears in white matter. The introduction to the topic includes summary of methods for estimation of diffusion profile and basic tracking algorithms. In this work diffusion tensor model (DTI) was used for estimation of diffusion profile. Based on the DTI, vector field characterizing direction of diffusion for every voxel was created. Combining vector field with seedpoint, we achieved task solvable by Euler or Runge-Kutta method. Termination criteria were established for maximum curvature of trajectory and minimum value of fractional anisotropy (FA). Algorithm was tested on mathematical and tractographical phantom before it was used on real biological data. The results of tracking on phantoms proved the funcionality of the algorithm. Expected error appeared in areas of crossing fibers, it is related to DTI model limitations. To solve problematic fibers characterized by seedpoint near the border of the fiber, FA-weighted trilinear interpolation was designed. Implementation of this algorithm, however, did not cause better results. The results of tracking on the real data were controversial. Tracking was performed on 5 healthy subjects and 4 anatomicaly specific tracts. The results were compared with tractographic atlas.

Airtightness estimation of wood based residential houses using Blower-door test
Srba, Jaromír ; Böhm, Martin (advisor) ; Trgala, Kamil (referee)
This dissertation analyses airtightness of residential buildings which in many ways influences their energy performance and therefore also their costs of use. Properly conducted airtightening layer can significantly extend the lifespan of the construction. The main objective of the dissertation is to evaluate the construction of newly built buildings in the Czech Republic and to assess the most important parameters which affect airtightness.
The Blower-door test was used to assess air leakage. This method belongs among the most widely used and conclusive methods of analysis. Its advantage is mainly the fact that it can detect construction defects of the airtightening layer in important stages of construction (and possibly enable these defects to be corrected before completion). The core of this method is to create a pressure difference of deltap 50 Pa between the exterior and the interior of the building and at the same time discover the faulty places which are different for positive and negative pressure.
The air leakage was assessed in 345 residential buildings constructed between 2006 and 2016, especially in conventional wood frame buildings or with buildings made from wood panels such as cross-laminated timber. The development of values of air change rate through the building envelope was evaluated according to the Czech standard ČSN 73 0540-2 and the results were compared to previous outcomes of other authors. Analysis and photo documentation of the most frequently detected leakage points are also part of the dissertation. A significant decrease in values of the air change rate was discovered, on average by 40.49% in 2016 compared to 2006, while for passive houses the air change rate values were almost steady. For buildings with wood frame construction, it was the way of ventilation which was determined as the most significant parameter affecting air leakage. For wooden buildings with natural or combined ventilation, the average value of air change rate at the pressure difference of 50 Pa was 1,29 h-1, for buildings with mechanical ventilation and heat recovery it was 1,18 h-1 and for buildings with very low energy consumption for heating with mechanical ventilation and heat recovery it was 0,44 h-1. Other parameters affecting the values of air leakage include the construction company, the presence of a chimney, the place and method of construction of the wood frame construction.

Application of analytical techniques and chemometry for authentification of wine
Pořízka, Jaromír ; Karovičová, Jolana (referee) ; Jarošová, Alžběta (referee) ; Diviš, Pavel (advisor)
This PhD. thesis is focused on application of different analytical techniques for determination of elemental composition of Moravian wine combined with analysis of selected polyphenol compounds. Two spectrometric techniques were used for elemental analysis of wine – Mass spectrometry and Optical emission spectrometry with inductively coupled plasma (ICP-MS and ICP-OES). Analysis of organic constituents of wine was evaluated by High performance liquid chromatograph with diode array detector (HPLC-DAD). Data from analysis of wine were used for construction of mathematical models for determining geographical origin of wine and for determining type of varietal wine. Data handling was performed by usage of multivariate statistical methods (cluster analysis, principal component analysis and canonical discriminant analysis). For the discrimination of wine by the geographical origin, two separate models for white and red wine were constructed. Effectiveness of discrimination of Moravian wine (with knowledge about origin) into 4 wine regions was 100 % successful for white wine and 96,43 % for red wine samples. Those models were used for cross validation test of unknown samples with result 95 % successfully classified samples of white wine and 82,15% of red wine. Besides that, mathematical model for discrimination and classification of varietal wine was made. Müller Thurgau, Riesling and Gruner Veltliner were discriminated by the usage of 8 elemental parameters. Discrimination success rate of known samples was evaluated by canonical discriminant analysis with 95,83% of correctly classified known samples and 70,83% of correctly classified unknown varietal wine (cross validation test). In addition to these part of research, impact of different grape production systems on elemental composition of wine and Vitis Vinifera was studied. The core of the study was to find the connections between the type of agriculture and chemical properties of wine and Vitis Vinifera. Two agriculture systems were assessed – Organic agriculture and Integrated pest management. . Results of this study showed that quantity and manner of pesticide application is very important factor affecting the final elemental composition of the grapevine and wine, especially the content of copper, zinc and manganese. That knowledge can be used in the future for creation of classification model of wine according to grape production system. For comparison of radical scavenging activity, electron paramagnetic resonance spectroscopy (EPR) with DPPH method was used. In the case of this study, the influence of vine growing under different farming systems on the total antioxidant activity of wine was found to be insignificant.

Pikal, Daniel ; Scheu, Harald Christian (advisor) ; Šmejkal, Václav (referee)
The purpose of this thesis is to analyze the current legal issue concerning the corporate mobility within the European Union. The main focus is placed, in particular, on the analysis of the relevant case law of the Court of Justice of the European Union. Other parts of this thesis will give an overview of cross border mergers and supranational forms of companies including their ability to transfer their seat to other member states without being wound up in liquidation before the transaction within the area of the European Union. As evident from the title, the paper focuses on the topic from the European perspective only and the issue of the mobility from, or into, a non-member state is not dealt with. The first chapter provides a brief definition of the basic legal concepts that are crucial to this thesis. The definition of freedom of establishment in the context of the common market of the EU is given and also the incorporation theory and the real seat theory are briefly outlined, as well as the conflict that may arise between these two doctrines. The second chapter, the most extensive chapter which represents the core of this thesis, describes and analyzes the case law of the Court of Justice of the European Union law relating to the freedom of establishment. This chapter is divided into two...
