Selected questions of the international sports law
Vybíral, Petr ; Brodec, Jan (referee) ; Pauknerová, Monika (referee)
The theme of the rigorous thesis is selected questions of the international sports law. Sports activity indeed starts at the level of particular states, but in connection with professional sportsmen's easy cross-border movement and with regard to unifying sports rules it is necessary to emphasize its international nature. Even it may be questionable to talk about international sports law it is not important to this paper, because the main purpose of the thesis is to deal with basic relations which are setting in sport with international element and to legally subsume them. As international sports law is newly aborning subject it is quite difficult to give it rational sort. This thesis is split into six chapters which are subdivided into subchapters, except for the first one. First chapter is generally about sport. The second concerns with the grounds of international sports law. Chapter three comprises sources of law that are associated with sport. Chapter four is focused on the professional athletes, their status and their activity. Fifth chapter deals with the organization of sporting activities. The last one is aimed at the settlement of disputes in sports area. The main conclusions of the thesis are following. Because of the system of sports organization we can say that it is possible to see...

Hladík, Petr ; Pospíšil, Jiří (referee) ; Hrabovský, Jozef (advisor)
The subject of this diploma thesis is experimental and numerical assessment of the heat transfer coefficients during condensation of water steam in simplified parts of an industrial steam turbine. This simplified part is a pipe with circular cross section, which is often used in simulations of processes inside the steam turbine. The first part of thesis describes theoretical basics of heat transfer during conduction, convection and condensation. The content of other chapters is description of methods used to determine heat transfer coefficient. These are: ex-perimental analysis performed on a measuring device and evaluated using finite element ana-lysis (FEA), computational fluid dynamics analysis (CFD) in ANSYS CFX and analytical calculations of heat transfer coefficients using mathematical models for condensation. Thesis is concluded by validation and comparison of obtained results.

Analysis of applicability and transferability of the corporation tax losses within the EU
Fuksová, Barbara ; Říhová, Lucie (advisor) ; Vančurová, Alena (referee)
This thesis analyses the treatment of tax losses in the Czech Republic in national and cross-border situations in the context of the recommendations of the European Commission and trends in treatment of losses, based on the cases of the European Court of Justice. Lack of immediate relief for losses leads to asymmetry of taxation, which is one of the causes of limitation functioning of the EU internal market. The comparison with other EU Member States based Czech Republic as a country with below-average possibilities of obtaining relief for losses. These include the 8 Member States have not yet adopted any national system of group taxation. Ways to get immediate relief for losses in domestic situations, including remains fiscally transparent entities in the group structure. Cross-border loss relief is available only if doing business in certain countries either by means of transparent entities or permanent establishments. This method of obtaining relief for losses is contrary to the interpretation of freedom of establishment, according to which there should be no discrimination on the basis of the legal form of business.

Companies in private international law
Hubinský, Igor ; Brodec, Jan (advisor) ; Dobiáš, Petr (referee)
60 Resume (Corporations in Private International Law) Free cross-border movement of companies became a new challenge for the European Law in last 30 years and surely changed the old theorems of private international law, concerning the companies at least. Although it is exactly the companies who are the most important factor shaping the European economy, legislature has not paid much attention and did little to facilitate their cross-border transfer. Under those circumstances, it has been the European Court of Justice (today Court of Justice of European Union) who has played the crucial role in interpreting the rights the European citizens under the Treaty should enjoy. But performing this enormously difficult task and under the scrutiny of European legal commentators it often got criticism, mostly for the inconsistency in his approach to construction of articles regarding the freedom of establishment. In my work I focused on the most relevant cases and attempted to point out underlying arguments in Court's reasoning. I tried not to set its judicature in debate over traditional issues regarding connecting factors since I think that question of freedom of establishment in European context should move to slightly different area of law. Nevertheless few pages of my work are devoted to these issues, where I...

The Czechoslovak legionnaires in the Far East
Hošek, Martin ; Lomová, Olga (advisor) ; Šedivý, Ivan (referee) ; Liščák, Vladimír (referee)
This thesis deals with the exploits of Czechoslovak army in Russia towards the end of the First World War. In 1918 it was transferred from the theatre of war in European Russia to the Far East via Siberia and from there by the A11ied navies to Europe, according to the A11ies plans to use them to strengthen the war against the Germans on the Western front. It deals in particular with the so called Vladivostok group, the avant-garde of the Czechoslovak army, which, though bound for France, returned to Siberia in order to reinforce the other Czechoslovak units locked in conflict with the Bolsheviks for control of the Trans-Siberian railway. The author of this thesis, who is a sinologist, therefore focuses his attention on the period of transportation along the Chinese Eastern Railway in the second half of 1918. This involves an analysis and clarification of the very complex situation when the Czechoslovak legionnaires were crossing Chinese territory and their controversial employment in the Allied intervention against Soviet Russia, which was manipulated by the Japanese army to further its expansionist aims in the Far East.

The effect of active recovery and hydroterapy on the subsequent short-term and medium-term muscular performance
Strejcová, Barbora ; Süss, Vladimír (advisor) ; Pavlů, Dagmar (referee) ; Pyšný, Ladislav (referee)
Title: The effect of active recovery and hydroterapy on the subsequent short-term and medium-term muscular performance Objective: The aim of the study was to compare the effect of two recoveries (ice pack, passive recovery) on the subsequent short-term and three recoveries (active recovery, cold water immersion, passive recovery) on the medium-term knee strength in the extension and flexion. Methods: Fourteen athletes in an average age of 26,6±4,4 years performed, in a random cross-over design, 2 sessions with 5 repeated short-term isokinetic tests and 3 sessions with 3 repeated medium-term isokinetic tests. The effect of ice packs and passive rest and the effect of active recovery, passive rest and cold water immersion were assessed by the 5x2 (time x recovery) and 3x3 (time x recovery) repeated-measure ANOVA, respectively. Results: The ice packs did not have any effect on peak torque, total work and average power during short-term performances. The average heart rate was significantly lower during measurements with the ice packs than during the passive recovery (125±15 vs. 135±20 tepů. min-1 ). We stated significantly lower changes in knee extension for the peak torque after the active recovery (↑ 0,9 N.m) than after the cold water immersion (↓ 14,6 N.m) or the passive recovery (↓ 13,9 N.m). The...

Induced fluid rotation and bistable fluidic turn-down valves (a survey)
Tesař, Václav
Paper discusses engineering applications of mutual interaction between fluid flow rotation in adjacent cavitiesthat communicate via a window through which is transferred moment momentum. The transfer may be merely byshear stress on the interface or enhanced by some flow crossing the boundary which is in the window. The first case of zero-time-mean mass transport through the window has led to methods of measuring the wall shear stress – a quantity of high importance in theoretical fluid mechanics – by measuring the speed of induced rotation in an adjacent vortex chamber. The case with momentum transfer by a non-zero flow became the starting point of development of fluidic valves combining two properties otherwise mutually incompatible: bistability on one side and turning-down the flow on the other side.

Potential of the sentinel-2 red edge spectral bands for estimation of eco-physiological plant parameters
Malenovský, Zbyněk ; Homolová, Lucie ; Janoutová, Růžena ; Landier, L. ; Gastelluetchegorry, J-P. ; Bertholt, B. ; Huck, A.
In this study we investigated importance of the spaceborne instrument Sentinel-2 red edge spectral bands and reconstructed red edge position (REP) for retrieval of the three eco-physiological plant parameters, leaf and canopy chlorophyll content and leaf area index (LAI), in case of maize agricultural fields and beech and spruce forest stands. Sentinel-2 spectral bands and REP of the investigated vegetation canopies were simulated in the Discrete Anisotropic Radiative Transfer (DART) model. Their potential for estimation of the plant parameters was assessed through training support vector regressions (SVR) and examining their P-vector matrices indicatingsignificance of each input. The trained SVR were then applied on Sentinel-2 simulated images and the acquired\nestimates were cross-compared with results from high spatial resolution airborne retrievals. Results showed that contribution of REP was significant for canopy chlorophyll content, but less significant for leaf chlorophyll content and insignificant for leaf area index estimations. However, the red edge spectral bands contributed strongly to the retrievals of all parameters, especially canopy and leaf chlorophyll content. Application of SVR on Sentinel-2 simulated images demonstrated, in general, an overestimation of leaf chlorophyll content and an underestimation of LAI when compared to the reciprocal airborne estimates. In the follow-up investigation, we will apply the trained SVR algorithms on real Sentinel-2 multispectral images acquired during vegetation seasons 2015 and 2016.
