Sensitivy analysis of the influence of manufacturing inaccuracies on the nuclear fuel reactivity
Sedlák, Martin ; Katovský, Karel (referee) ; Novotný, Filip (advisor)
This thesis deals with a sensitivity analysis of the influence of manufacturing inaccuracies on the reactivity of nuclear fuel. Sensitivity analysis has been done for fuel assembly TVSA-T, for nuclear reactors VVER-1000. Particularly, for fuel rod of type tvel - without burnable absorbers. Thirty three combinations of maximal and minimal of manufacturing parameters were simulated in SCALE environment. Changes of multiplication coefficient in dependence on burnup for 5 combinations have been also studied. It has been found that the most significant influence on the reactivity has the accuracy of enrichment and outer diameter of cladding. It has also been found that influence of manufacturing inaccuracies is not constant during burnup. The benefit of the thesis is determining the effects of individual inaccuracies on the reactivity and the fact that their influence is not constant during burnup.

Analysis of Indicators of Vehicular Traffic Accidents in the ČR
Sedlák, Martin ; Princ, Lubomír (referee) ; Kropáč, Jiří (advisor)
This bachelor thesis deals with car accidents. It focuses on analysis of influence accident´s indexes and their partial prognosis for the future. It researched the number of accidents, their seriousness and the amount of material damage. Attention is focused on vehicle´s park and age of vehicles. This analysis is performed primarily for the use of time series. Materials for analysis are taken mainly from statistical data of the Police of the Czech Republic. Furthermore, the work addresses the impal of legislative changes already made, which should lead to improvement of the current state. In the propered solution is outlined possible steps to resolve the issue and evaluace previously adopted legislative changes or other state intervention.

The Application of Fuzzy Logic in Insurance Business
Sedlák, Martin ; Kittner, Petr (referee) ; Dostál, Petr (advisor)
The dissertation looks into the problematic of evaluaing the customer's solvency. It specifically focuses on using the Fuzzy logic when calculating the correct value of the third party insurance, as it is a legal requirment by law in the Czech republic, applying to every motor vehical in use. The first part of the dissertation analyses existing calculation system. As there doesn't exist any unifed fiugre table, an indicative price list has been created by using accessible sources. This price list helped to optimalize variable quantity when inventing own model to be put in practice. Suggested solutions have been made by using the MS Excel and MATLAB programs. Newly created models consist of some parameters which havn't been used for the calculations yet, but can help achieve higher objectivity when assessing the insurance figure. The dissertation aims to prove that similar problematics could be successfully solved by applying the Fuzzy logic technic.

Fatigue Properties of Stainless Austenitic Steel
Sedlák, Martin ; Němec, Karel (referee) ; Věchet, Stanislav (advisor)
Final bachelor thesis „Fatigue characteristics of anti-corrosion austenitic steels" is aimed at problematic of mechanics and fatigue properties of Chrome-Nickel austenitic steel CSN EN X2CrNiMo 18-14-3. Thesis aim is to pass judgment on influence of stress cycle asymmetry on fatigue characteristics on high cyclic loading on above mentioned steel. Design Haigh and Smith diagrams. Component of the thesis is metallographical and chemical analysis, mathematical values processing obtained from fatigue tests and also determine primary mechanical properties. Further Wohler´s curves are stated at different stress cycle asymmetry. According to mathematical values processing is designed Haigh and Smith diagrams and fatigue index is calculated. From obtained data result that medium stress of cyclic stress, has of principle influence on appreciate fatigue limit of engaged material.

The spread of the significant neophyta in the Novohradské hory and their foot-hills
SEDLÁK, Martin
In the area of interest the occurence of selected alien plants have been mapped. Their approximate abundance have been determined, as well as the locality, which is occuppied by certain species and the enviroment in which alien species occurs. The centres, out of which the species spread out have been determined or estimated, as well as have been estimated tendencies for their possible future expansive. The changes in the occurence in stated vegetation periods have also been introduced and the fact whether the species seems to be expansive or stationary. Localities of the occurence of alien plants have been drawn into maps, which are parts of the supplement.

Munich Transport and Tariff Association
Sedlák, Martin ; Zelený, Lubomír (advisor) ; Itterheim, Martin (referee)
This final bachelor thesis describes the theoretical nature of the integrated transport systems, their advantages and disadvantages in general and their future development. The main objective is to analyze a particular integrated public transport system or more precisely The Munich Transport and Tariff Association, and last but not least compare with other integrated transport systems of other urban areas in Europe.
