Architecture of the extreme
Válek, Ondřej ; Albert, Novák (referee) ; Kaftan, Martin (advisor)
"The need to get food, build a camp resistant to storms and torrents drove us all to work. The leader worked together with us, but did not make the conditions easier for us. On the contrary, the order to use in the construction on the site of tree boards, which we had to cut down and process in the thickets, meant a new piece of work. Sometimes, tired of remorse, I remembered home, especially when the still rain and gloomy sky discouraged us newcomers. However, what kept me going and pushed me forward was the interest in this Robinsonade and my pride. I didn't show the feelings that were shaking through me at the time. If the others can handle it, I will persevere as well. My nature can't stand me standing last. And this pride helped me overcome femininity. So I remembered my beginnings as scouting and felt a warm joy at the calm awareness of my fitness today. ” _Jiří Wolker: To those to whom I belong //Project goal The main goal of this work coincides with the mission and purpose of the association Junák - Czech Scout, z .: "To support the development of young people's personalities in accordance with the principles and methods of scouting." //Means The means to fulfill the main goal is to build a scout camp in which children are involved. Specifically, 25 boys aged 7-15 who are members of the 14th Regulus Líšeň section. Together with 10 other leaders, they go to the "Hodíškov" camp every year, where they spend the first 14 days of the summer holidays. The construction of the camp is preceded by a design, which is the subject of this work.

STIFFNESS ANALYSIS OF FRONT PART OF THE VEHICLE
Coufal, Tomáš ; Kovanda, Jan (referee) ; Kohút,, Pavol (referee) ; Vémola, Aleš (advisor)
The thesis deals with the front part stiffness of modern vehicles, especially for the use in the field of forensic engineering in the traffic accident analysis. During the traffic accident analysis, an inquiry into the collision between vehicles is carried out which is an integral part of determining the energy loss of the vehicle at the impact, or more precisely the deformation energy expressed in the form of Energy Equivalent Speed (EES). In case of known stiffness of given part of the vehicle and based on the depth of deformation, it is possible to calculate the deformation energy, or more precisely EES corresponding with given damage of the vehicle. In the field of forensic engineering, the values of stiffness of individual vehicle components are not known and therefore, alternative methods are used to calculate the EES, they are outlined in the research part of this dissertation. However, the current methods of EES determination have some limitations when it comes to usability, and therefore, new EES calculation for the front part of the vehicle was designed in the research. It was based on the real crash test results using real stiffness characteristics of the front part of a vehicle. The front part of the vehicle is divided into individual areas and each of these parts is characterised by its own stiffness coefficient. The designed EES calculation can thus be also used for collisions with partial overlapping, taking into account the real stiffness of the damaged part of the vehicle, which was not possible with existing methods. In the research part of this dissertation, a computer programme to calculate deformation energy and EES was processed. It works with individual stiffness characteristics in given areas where the input data are entered by the user and include the depth of permanent front part deformation in individual areas, vehicle weight, the direction of an impact force and the friction coefficient on the contact surface. Considering the fact that the vehicle stiffness is also one of the control parameters at solving collisions in the PC-Crash simulation programme, which is used in forensic engineering practice for the analysis of a collision process, a supplementary computer programme was designed. Based on the above-mentioned input data, the supplementary programme can further calculate data for collision solving in the simulation programme, namely stiffness, restitution coefficient and the vehicle damage stated in the output report of the simulation programme. Based on these data, the expert thus has the opportunity to solve the collision of two vehicles in the simulation programme with as much preciseness as if it was a real collision.

Information of the population and employees of Temelín NPP on evacuation in case of a radiation emergency
RYBÁK, Tomáš
The aim of the thesis was to compare the awareness of employees of the Temelín nuclear power plant and the general public about evacuation in the event of a radiation emergency. For this purpose, a questionnaire survey was carried out. Questionnaires were distributed and filled out using an internet tool for creating questionnaires at survio.com stands. The theoretical part of the work is focused on the Temelín nuclear power plant, its geographical location and technical description. The work is also focused on the radiation safety of nuclear power plants, their workers and residents against radiation. In the theoretical part, selected accidents of the Jaslovské Bohunice, Chernobyl and Fukushima nuclear power plants are further described. For the purposes of the practical part, the same questionnaire was created for the employees of the Temelín nuclear power plant and the general public. The questionnaire is composed of 34 questions. The first 4 questions serve to divide the respondents, and the remaining questions determine the awareness of the respondents about evacuation in the event of a radiation emergency. A total of 100 respondents took part in the survey - 50 employees of the Temelín nuclear power plant (50%) and 50 respondents from the general public (50%). The survey results were evaluated using the internet tool survio.com and the Microsoft Excel software program. The aim of the thesis was to compare the awareness of the general public and employees of the Temelín nuclear power plant about evacuation in the event of a radiation emergency. From the questionnaire survey, it is evident that the level of awareness of the employees of the Temelín nuclear power plant reaches 86%, and the general public only 68%. The result shows that employees are better and more informed than the lay public. Based on this investigation, I would recommend informing the public more about evacuation options in the event of a radiation emergency.

Evaluation of introduction protection measures - evacuation at crash of nuclear power station Fukushima
SLÁMA, Filip
The aim of this bachelor thesis is to evaluate the protective measures, notably the evacuation of the population, its development and progress. To achieve the goal of bachelor's work was determined by the research question: Was the safeguard measures and the subsequent procedure for the evacuation of persons from the evacuation zones sufficient? The theoretical part is focused on the particular issue of nuclear power plants, radiation protection and evacuation. The situation described here, which took place directly on the Fukushima daiichi nuclear power plant Daiichi, from the strike of the earthquake and tsunami, after the gradation events in the individual reactors. The research part is about the development of the evacuation in the evacuation zones and the nuclear power plant. Protective measures are described here, and even the consequences and the situation after the crash to the present. The methodology of this work was the gathering of available information from official foreign sources, legislative documents, but also of the publications of the experts. Processing of the available information and the evaluation of the consequences of the evacuation has brought unpleasant findings. The loss of life, which can make a person look a certain way to reflect over the selection of persons suitable to evacuate. In this work were identified and discussed technical shortcomings of the power plant, the information misconduct in communication of the population and in the last row and misconduct of the human factor. The thesis can be used in the general issue of nuclear power plants and evacuation for study purposes or as an information source in the education, energy or public administration.
