Membership in the sport association
Poláková, Kateřina ; Kohout, David (advisor) ; Svatoš, Martin (referee)
Membership in the sport association Abstract This thesis deals with the issue of membership in an association from the perspective of the applicable law and analysing the internal regulations issued by the associations themselves. The aim of the thesis is to comprehensively present the matters of membership in an association as the most common legal form active in the sports environment. The first part of the thesis is dedicated to the Right of association, on which the law of association is based. As well as the related issue of voluntary membership of athletes in sports organisations. The legal regulation influencing the form of sports associations is presented in the second part of the thesis. Attention is not focused only on the Civil Code as the leading document of the association law, but also on the Act on the Support of Sport and other regulations. The main association's regulation is the articles of association, which specify the association internal order. The association cannot be in existence without the articles of association at all. The internal regulations issued by the association also have an important position in the association, but their binding is not result from the Civil code. Previously it briefly introduces the association itself and the subsidiary association. Afterward it...

Professional ice hockey player contracts
Přibyl, Jakub ; Kohout, David (advisor) ; Svatoš, Martin (referee)
Professional ice hockey player contracts Abstract The topic of this thesis is professional player contracts in ice hockey. It is a very specifically chosen topic of the thesis, the main aim of which is to analyze the subject of individual player contracts. In order to achieve this, however, it was necessary to first set out the smaller sub- objectives of the thesis. These minor objectives will help to introduce the subject in a sufficient manner and also serve as a basis for the subsequent analysis of the problematic provisions of the players' contracts. The minor objectives were to set out the concept of "sport" and its division, to point out the insufficient legal regulation of professional sport in the Czech Republic and to compare activities of a professional hockey player with employment status and with entrepreneurship. In the las and main chapter, I aimed to analyze in detail the professional player contracts in ice hockey, their individual arrangements and to point out the problems caused mainly by the absence of legal regulation of professional sport and the autonomy of the will of the parties, especially the stronger party, the ice hockey club. Key words: player contract, professional sport, ice hockey

Based on true story
Davydenko, Polina ; Kohout, Martin (referee) ; Gravlejs, Ivars (advisor)
In reaction to the process of collecting photo series, I decided to focus on how not to rely on safe shots. I have created a set of images from which viewer can read several meanings, thanks to the overall absence of narration and text. I am looking for stucture and possibly creating new images building on this found structure.

Influence of a Free Surface and Gradient Change of Material Properties on a Crack Behaviour
Ševčík, Martin ; Kohout, Jan (referee) ; Klusák, Jan (referee) ; Náhlík, Luboš (advisor)
This thesis was written under the supervision of Assoc. Prof. Luboš Náhlík, Ph.D. and Assoc. Prof. Pavel Hutař, Ph.D. The topic of this thesis is the study of a free surface effect and gradient change of material properties on a crack behavior. The common theme of the work is a fracture mechanics description of a crack behavior near a material nonhomogeneity. Here, the material nonhomogeneity can be understood either as a boundary of a body (interface between body and surrounding) or as a continuous change of material properties. The thesis is introduced by a review part where the state-of-the-art of the concerned topic is described. This part presents several stress state descriptions in the vicinity of some general singular stress concentrators, particularly a crack and a V-notch. The influence of the free surface on a fatigue crack front shape is discussed here. The review part follows with the fracture mechanics description of the graded materials. The problem formulation and the main aims of the thesis are stated in the following chapter. The core of this work is the fracture mechanical description of a crack propagating near the material nonhomogeneity. The thesis focuses on a stress field description near the free surface of the body where a change in a type of the singular stress field occurs. Methods used in generalized fracture mechanics are applied here to describe the stress field near the free surface. The difference between crack behavior in thin-walled and thick-walled structures is shown and supplied by relevant examples. Methods and procedures used are later utilized for estimation of a crack behavior in graded structures. The thesis is concluded by the discussion of obtained results in appropriate context.

Development of Long-pitch Corrugation in Curves of Small Radii
Valehrach, Jan ; Kohout,, Martin (referee) ; Lidmila,, Martin (referee) ; Plášek, Otto (advisor)
Throughout the operation, the rails are worn and deteriorate. With the increasing speed of rolling stock, along with higher track loads and especially in the vicinity of major traffic hubs with a higher frequency of trains, defects that did not occur to such an extent before or were not considered to be significant, are brought to the forefront of the concerns of track infrastructure managers. Even though these defects are not directly restrictive to traffic operation, they are, in any case, a source of noise and vibration. One of these defects on the railway track is the micro-geometry defect of the running surface of the railhead. In directional curves with radii of less than 600 m or 700 m, defects known as long-pitch corrugation occur on the inner rail. In curves with 300 m or smaller radii, these waves are so distinct that they are a significant source of noise and vibration. In particular, vibrations affect the track surroundings and the track itself, as they cause other defects in the track structure. This dissertation deals with long-pitch corrugation, focusing on the monitoring of wave generation and development over time. The verification of the possibility to track the development of slip waves over time is the basis for possible future models predicting the development of defects. Numerous measurements of geometric parameters of the track and microgeometry of the railheads, specifically slip waves, have been carried out in the framework of the problem. Using RMS and peak-to-peak methods, the rate of development of defects over time and the relationship with other track parameters were evaluated. Based on the obtained development curves, intervals for further maintenance interventions were estimated. A part of the thesis focuses on the deficiency or excess of cant concerning the development of long-pitch corrugation.

Methodology for designing the dead end tracks
Guziur, Petr ; Týfa,, Lukáš (referee) ; Kohout,, Martin (referee) ; Svoboda, Richard (advisor)
This work aim is designing of dead-end tracks with focus mainly on the friction buffer stop design. There are numerous factors in decision-making process of ending the dead-end track, such as position of the track in station, level of train control system, area capabilities, number and types of trains that regularly run on the track, etc. The recherche part of this work shows that friction buffer stop is the most suitable construction and preferred type of ending the dead-end track abroad. This is the reason for paying attention to that type of buffer stop with emphasis on the process of design itself. This work includes design of a program using a spreadsheet editor and Visual basic to make the design of friction buffer stop easier. There are described selected factors with highest impact on the design.
