Development of astronomical telescope control system with satellite tracking
Juráň, Jakub ; Musil, Vladislav (referee) ; Háze, Jiří (advisor)
The focus of this thesis is a development of an electronic guiding unit for a mount of an astronomical telescope allowing observations of artificial satellites orbiting the Earth. It contains a theoretical study of methods developed for the description of positions of objects observable on the celestial sphere, including systems used for storage of this information and regaining it in order to point the telescope in a specific direction. The work includes an analysis of the present supply of commercial devices, followed by a detailed description of the design developed here and its components. Finally, there is outline of possibilities of a future development of the system, focusing on software components.

Code Structuring in Decompiler Back-End
Porwolik, Tomáš ; Kučera, Jiří (referee) ; Matula, Peter (advisor)
This thesis deals with a decompilation tool which converts low-level binary code to a high-level representation. This tool is being developed by AVG Technologies. The aim of this work is to design and implement a method for code structuring in the decompiler back-end. The designed method works by traversing the control-flow graph with matching of predefined patterns. It is not always possible to structure code using conditional statements and loops. Sometimes also goto statements must be used. The implemented solution is compared with the original solution in the decompiler. According to the results the new solution is faster, better tested, but in greater number of test cases generates invalid code. From the viewpoint of structuring the results are different and sometimes the code is structured better, but sometimes worse.
