Noise of Aircraft Jet Engines
Szelke, Ludvík ; Vacula, Jiří (referee) ; Novotný, Pavel (advisor)
In my bachelor's thesis I try to present the noise sources of aero-jet engines. First, I introduce the reader to a brief history of the development of jet engines and the principle of jet engine function. Then I continue with general knowledge about noise itself, what it is measured by and what effects it has on our lives. This is followed by an analysis of the sources of jet engine noise, both theoretical and using a computer model. At the end of my thesis, I mainly discuss the possibilities of noise reduction for the sources, and also possible future developments.

Szelke, Ludvík ; Roupec, Jan (referee) ; Matoušek, Radomil (advisor)
This thesis deals with the design of applications used to control, manage and display all the information needed for the smooth operation and play of the game of European bowling. In the first part of this thesis, the history of digital dashboards and the sport of bowling is presented, along with an explanation of the rules for designing applications. The practical part of the thesis presents the initial development of the applications. All the applications are introduced in turn, their structure is explained, and finally their testing is presented.
