Vortex tube
Chýlek, Radomír ; Škorpík, Jiří (referee) ; Pospíšil, Jiří (advisor)
The purpose of this diploma thesis was to find optimal operational parameters of Ranque–Hilsch vortex tube that would give the best results of temperature separation, and to create a numerical model of the device. Firstly, extensive research of current literature was done and analytical model of the tube was created. Then, the numerical model of the vortex tube was designed using Star-CCM+ software. Afterward, best fitting turbulence model was chosen to do the calculation and optimal geometrical parameters of the tube were obtained as a result of CFD simulation. Then, inlet nozzles for the tube were designed and manufactured. Experimental evaluation of the vortex tube and description of its optimal settings form a substantial part of the project. Finally, the data obtained from the experiment were compared to the results of numerical analysis and conclusions were deduced.

Processing Journal Articles For a Digital Library
Šlapáková, Ivana ; Jansová, Linda (advisor) ; Drobíková, Barbora (referee)
(in English): The aim of presented master thesis is to suggest the optimization of articles processing in the Digital Library of the Academy of Sciences of the Czech Republic. The present state of journal articles processing is described and the weaknesses are evaluated. The journal articles processing optimization is suggested in two steps. The first step is to choose only one integrated library system for journal articles processing. The second step is using the system of shared cataloging and the proper use of three external resources. The main contribution of this thesis is the deep evaluation of the external journal articles records resources and the process of shared cataloging. Fifteen journals were proposed to the process of shared cataloging and record downloading but only five of them are suitable for this process.
