Characteristics of fan cooling towers
Joska, Jakub ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the problematics of fan cooling towers. The very first part of the text is research, focusing mainly on the theory of cooling and the function of fan cooling towers in general. The following chapter deals with the water resource management of the Dukovany nuclear power plant and the specification of its objects of forced draft cooling towers. The second part describes a computational model created to determine the cooling performance of these towers under the given input conditions. In the following chapters, the results from the computational model are compared with the available data from warranty measurements and with the provided characteristics. The final pages deal with the study of the influence of changes in input parameters on the cooling performance and the research of the behavior of the cooling towers under extreme weather conditions.

Introduction to Six Sigma Method and its Application for Process Improvements
Joska, Jakub ; Žák, Libor (referee) ; Bednář, Josef (advisor)
First part of the thesis deals with the description of Six sigma method and its most commonly used methodology DMAIC. The second part is a brief introduction of specific practical problem - electroforming. The third part describes the statistical tools used to solve the given task, especially the Pearson's chi-squared test of independence. The last part of the thesis contains a summary of data, calculation itself and data analysis results.
