Analysis of heat exchanger
Nosek, Miroslav ; Kilkovský, Bohuslav (referee) ; Jegla, Zdeněk (advisor)
The diploma thesis is focusing on research of possible damage mechanism of U-tubes in a heat exchanger placed within a gas waste incinerator unit in a factory dealing with chemicals manufacturing. In the first phase of the research, in which a thermo – hydraulic calculation is being made, a specialized software tool HTRI Xchanger Suite® v6.00 is used. Using the software it is possible to simulate certain operational conditions in which the heat exchanger operates. The output from the first phase of the solution is to obtain a set of temperatures of the tube material throughout the length of the tubes. These data are consequently used in the second phase of the analysis. The second phase of the analysis is dealing with thermal lenght dilatation differences assessment between tubes in the tube bundle as a predected reason of oversize tension formed in tube material and damage following afterwards. Conclusions of the calculation made in the second phase of the analysis are then checked by calculation via ANSYS Workbench 11.

Energy use of biomass
Nosek, Miroslav ; Škvařil, Jan (referee) ; Moskalík, Jiří (advisor)
The point of this bachelor thesis is to make out a retrieval for energy use of biomass. In the first part, there is a description of basic energy features of biofuels, which influence their use as an energy source. There is also listed a description of some technologies for production of energy from biomass. The second part of the thesis is dealt with using biomass in cogeneration. Even that there is a description of some cogeneration systems presently use in any energy applications. In the trird part, there is made out a comparation of expensiveness of using conventional unit with natural gas combustion and using a units with biofuel combustion.

Legal standing and powers of mayor in the Czech republic and Schleswig-Holstein (comparison)
Nosek, Miroslav ; Kopecký, Martin (advisor) ; Vedral, Josef (referee)
The purpose of this thesis is to compare mayoral legislation status and his authority in the Czech Republic and Schleswig - Holstein. Although the main subject of the thesis is legislation status of the mayor each legislation chapter begins with a description of the autonomy constitutional right, municipality organization, and relationship of municipal authorities according to current legislation. The aim of the diploma thesis is to define the status of the mayor and his authority in the rule of law of the Czech Republic and Schleswig - Holstein and then use a comparative method to analyze the legislation differences and identical features. There are several parts of the thesis. In the first part is described legislation status of the mayor and his authority in the Czech Republic. The first chapter deals generally with a municipal and the second chapter is focused on the mayors authority, status, creation of mandate, responsibility and mainly on his competence. In the second part is described mayors legislation status and his authority in Schleswig - Holstein and contains third and fourth chapter. These chapters, as in the previous part, deal firstly with a municipal and secondly with the mayor specifically. In the third part is compared the legislation status of the mayor in the Czech Republic and...
