Analysis of structural response and design methods for shear walls in light timber frame structures
Zajíc, Michal ; Lokaj,, Antonín (referee) ; Kuklík,, Pavel (referee) ; Kuklík,, Petr (referee) ; Šmak, Milan (advisor)
The prediction of shear capacity of light timber frame walls in a multi-storey arrangement is the main focus of this dissertation. The available theories neglect to account for the fact that the shear resistance of the walls may depend on the actual vertical position of the applied horizontal force. However, the actual arrangement of the structures in practice introduces a vertical offset between the wall head height and the position of the resultant of the external horizontal forces. Thus, the horizontal shear force is accompanied by dependent overturning moment. Solving such a problem for partially anchored walls inevitably leads to an iterative calculation. The aim is to provide a comprehensible and less calculation-intensive procedure for multi-storey buildings that would be competitive with existing simplified methods. A model derived from lower bound plastic method was successfully put to the test in a parametric study and compared with limited test results. The results show that the capacities predicted using the novel method compare favourably with the results obtained from traditional theories using a more complicated iterative process. Therefore, the presented single-step approach may be appealing to the industry. A test program was formulated to understand better the implications of the recommended best practice of introducing gaps between sheathing panels. It was set to experimentally verify the difference in the shear capacity for setups with and without gaps between the sheathing panels. The significance of this study is that it informs the industry that the manufacturers’ recommendation to incorporate a gap between sheathing panels would not compromise the structural integrity. Considering the model uncertainty and the safety margins, the introduction of gaps does not alter the strength or stiffness of the wall.

Comparison of the liberalisation of the railway passenger transport market on the example of the Czech Republic and Austria
Zajíc, Marek ; Nigrin, Tomáš (advisor) ; Volf, Jaromír (referee)
The subject of this diploma thesis is a comparison of the liberalisation of passenger rail transport on the example of the Czech Republic and Austria. Based on the legislative framework of the European Union, which both countries have to follow not merely in the field of transport policy, the aim of the thesis is to compare the situation in the two neighbouring Central European countries. Regarding the research, literature and other sources, the thesis focuses on a comparative analysis of how the two countries, comparable in terms of size and population, approach liberalisation. In this thesis, I conclude that the liberalization of the EU passenger rail market process in the Czech Republic and Austria through railway packages is undertaken by different methods. Whilst in the Czech Republic the "vertical separation" is used, where the infrastructure manager and carrier are two different subjects, which leads to business competition objectivity, in Austria the infrastructure manager and the carrier remain in one holding arrangement in relation to the subsidiary companies. It is important to analyse both of the approaches continuously, especially with regard to the period of 2023-2033, which is to be the last transitional decade, followed by absolute liberalisation of the passenger rail market....

The displacement of the German population from the Šternberk area and its impact on the regional economy
Zajíc, Marek ; Šafařík, Petr (advisor) ; Nigrin, Tomáš (referee)
Abstract/Annotation The theme of this bachelor thesis is the influence of the displacement of German population from Šternberk on the local economy after 1945. The thesis deals with the state of Šternberk's economy before displacement and its development after the above mentioned year. The thesis contains statistical data on the original composition of the population and the number of trades and crafts. Furthermore, the largest employers in the city and the region are introduced. It is also stated in the individual chapters that the transformation of economy was not an exclusive issue in 1945, but was gradually taking place in different sectors. The sources I have worked with when writing the text prove that the character of the Šternberk region has been completely different from the present day for several decades. Through archival materials currently stored in Olomouc, it is possible to create a comprehensive picture of how the displacement of Šternberk Germans took place at the end of World War II. It is also evident from some of the selected sources that Šternberk and the North Moravian region were subsequently settled also by repatriates. The aim of this work is to acquaint the public with the preserved sources that provide insight into what was then happening in the North Moravian region.

Vliv onemocnění paznehtů na užitkovost a složení mléka dojnic
Zajíc, Martin
The aim of the work was to obtain data on performance and milk composition from performance control and to compare these results between a group of cows with diseases of the hoofs and healthy cows. The hypothesis has been verified as to whether the performance and composition of dairy milk is influenced by the occurrence diseases of the hoofs. Surprisingly, according to the results of this work, the influence of the studied diseases on the monitored parameters is relatively small. Proportional reduction in cow milking was confirmed only in one experimental group (reduction in milking for 3.38 liters, P <0.01). The affect on the results is probably also the fact, that the latent measure was not detected in the animals, but only the presence of problem hoof. The occurrence of limping (as a sign of pain) will probably influence the decrease in milking much more than individual finger diseases that are not painful enough to cause limping. Furthermore, the statistical significance of the increase in somatic cell counts (an increase of 67,000 SB / 1ml, P <0.05) in one monitored group of diseased dairy cows was demonstrated. However, the increase in the number of somatic cells may be caused by a number of other factors. Other studied milk composition parameters (fat, protein, lactose, ketone, urea, free fatty acids) were not significantly different between groups. On the basis of the evaluation and experience from the implementation of the study, the degree of limping of the cows would be considered as a factor for continuing research in the area.

Economical criminal acts in Spanish law
Zajíc, Martin ; Grmelová, Nicole (advisor) ; Žák, Květoslav (referee)
This bachelor thesis is about economical criminal acts in Spanish law and is divided into three parts. The first part describes basics of Spanish Criminal law, where some basic key words are explained, as well as the common features of economical criminal acts. In the second chapter differences between Czech and Spanish Criminal law are explained. There is also mention of the European Convention on Mutual Assistance in Criminal Matters and how it works. The final chapter is divided into two parts. The first part describes the results of analysis on Economical criminal acts worldwide that was carried out by PricewaterhouseCoopers and is concentrated on Spain. The second part of the last chapter is dedicated to analysis of Criminal law in the case of corruption and money laundering that the family of Jordi Pujol is guilty off.
