The study of the effect of additive manufacturing technology parameters Selective Laser Melting properties of the produced object
Žabka, Marek ; Koukal, Ondřej (referee) ; Vrána, Radek (advisor)
Metal additive technology currently finds use in a large number of industrial sectors. Mainly in domains such as aviation, medicine and astronautics, the emphasis is laid on mechanical and material properties of materials. This bachelor thesis deals with the research study of process parameters of technology Selective Laser Melting for material AlSi10Mg and stainless steel 316L. In thesis the impact analysis of main process parameters: laser power, scanning speed, hatch distance, layer thickness, especially on the porosity of the samples was carried out. Recommended settings for both materials were found based on the research of the current state. It was further found out the influence of parameters such as powder humidity or laser scan strategy.

Aerodynamic design of wind turbine
Žabka, Marek ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This Master’s thesis focuses on the wind turbines. It describes the basic attributes of the wind energy and the wind potential of Slovak Republic, as well as the environmental impact of this sector. Meteorological data for the selected location are processed according to the Weibull distribution and they are used for the aerodynamic design of the wind turbine blades. Aerodynamic design is processed by using two methods. The first is the blade cascade theory, which is used to design prismatic and twist blades. The second method is called the blade element momentum, which is used to design wind turbine but only twist blades are designed by using this theory. Calculated aerodynamic shapes are compared and the best economic solution for the selected location is chosen.
