Urban, Jiří ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis is an analysis of the construction of a trailer used for transporting concrete pillars. The main part of the thesis is focused on frame construction. For the calculation of load states a multi body system was used, whereby a simulation of transport in terrain was performed. The results from these calculations will be used as limiting conditions for strength control. The method of solution is the finite element method. All acquired results will be analysed and according to them changes will be made to the frame construction. In addition to this, the thesis contains drawings documenting the above-mentioned changes.

Simulated chemical accident associated with the release of phosgene
NOVÁK, Jan
The thesis entitled "Simulated Chemical Accident Associated with Phosgene Leak" focuses on the issue of disasters in general and specifically on chemical disasters associated with leakage of dangerous chemicals. The thesis consists of a theoretical and a practical part. The theoretical part of the thesis is divided into four subchapters. The first subchapter deals with accidents in general, and the classification thereof into natural and anthropogenic contingencies. The subject of the second chapter deals with specification of accidents that occur in the chemical industry. A special focus is given to causes of chemical accidents, among which there are anthropogenic (human factor) and technical causes as well as working conditions and organization of work. As regards classification, chemical accidents are divided into chemical accidents associated with leakage of dangerous chemicals, further accidents with leakage of radioactive substances and those involving oil leaks. With regard to the topic of the thesis, the third subchapter specifically focuses on characteristics of chemical accidents associated with leakage of dangerous chemicals. This is the key part of the theoretical basis of the thesis. The subchapter deals with causes, classification, development, characteristic effects and consequences of such accidents. Factors are also mentioned that affect the spread in the environment of dangerous chemicals leaked as the result of chemical accidents depending on a number of conditions. The fourth subchapter is linked to the preceding chapter in that it provides a brief characteristic of dangerous chemicals. A special focus is given to a comprehensive specification of phosgene. The core of the practical part of the thesis lies in the implementation of research consisting in simulation or modelling of a chemical accident associated with leakage of a selected chemical from a particular chemical plant. For the purpose of modelling phosgene was selected as the dangerous chemical. The company Synthesia, a. s. located in Pardubice, was chosen as the chemical plant in question. The practical part of the thesis aimed at modelling a chemical disaster associated with phosgene leak at Synthesia, a. s. The software tool TerEx, version 2.9.1. was used for simulation. Using this computer program a total of ten contingency scenarios were prepared involving phosgene leaks of different quantities as consequence of a chemical accident at Synthesia, a. s. Another aim of the practical part of the thesis was to assess risks following from the chemical accident. This assessment was made on the basis of the results of the TerEx program in the form of toxic exposure, recommended examination of toxic phosgene concentration within certain distance from the place of leakage, areas of necessary evacuation of the population, and last but not least time dependence of phosgene concentration and accumulated dose within distances of necessary evacuation of the population. The third and also the last aim of the practical part of the thesis was to assess impacts of this potential chemical accident on the health or lives of the population. The results of the modelled chemical accidents involving phosgene leak from Synthesia, a. s. showed that this contingency would especially impact health but not lives of the population. The phosgene concentrations showed only threshold levels (from 10 to 20 mg/m3) that would cause irritation of the eyes and the upper respiratory tract / nasopharynx. Even though the results of the research showed that no serious impacts on the health of the population should occur, the worst possible contingency scenario should always be considered in the event of such chemical accident.

Stress-strain analysis of arterial aneurysms
Tesařová, Petra ; Skácel, Pavel (referee) ; Burša, Jiří (advisor)
The diploma thesis is focused on the creation of the aneurysm finite element model and the making of the aneurysm wall stess-strain analysis using ANSYS software. The model of abdominal aortic aneurysm geometry starts from the CT scan of the particular patient. In the thesis there are compared two chosen constitutive models, each of them appears from different mechanical tests done on human arterial fibre samples. Furthermore, a limiting condition for aneurysm wall structure damage is expressed. On the basis of the results of stress calculation in the aneurysm wall and the limiting condition, the safety coefficient and rupture factors risk are worked out.

The Conclusion of a Contract under the United Nations Convention on Contracts for the International Sale of Goods in Comparison with Czech National Legislation
Krčálová, Kristýna ; Boháček, Martin (advisor) ; Levý, Jan (referee)
This Master's thesis focuses on the United Nations Convention on Contracts for the International Sale of Goods (CISG), better known as the Vienna Convention. The main purpose of this thesis is to evaluate conditions for application of this international treaty and to assess the contracting process under the CISG including the similarities and differences with the Czech national legislation. Finally, it seeks an answer to the question, which of these rules (international or national) are more advantageous for a Czech contractual party with respect to concluding a contract. The thesis is divided into five parts. The first one represents an introduction to the CISG, its origin and the Czech Republic's attitude to it. The second part identifies the conditions for application of the CISG and therefore defines a subject and an object of an international contract of sale under the CISG. Both third and fourth parts gradually introduce two phases of the contracting process (offer and acceptance) including the relevant case-law. The last chapter strives to complete the contracting process with an analysis of the exact moment, when a contract is concluded, as well as with an analysis of a potential battle of the forms and its impact on a contract conclusion.
