Surface Analysis by Photoelectrons – Computer Control of Experiments
Polčák, Josef ; Zemek, Josef (referee) ; Cháb, Vladimír (referee) ; Šikola, Tomáš (advisor)
Doctoral thesis is dealing with the methods for analysis of surfaces by photoelectrons being emitted by X-ray radiation. The methods are: X-ray Photoelectron Spectroscopy - XPS, Angle-resolved XPS - ARXPS and X-ray Photoelectron Diffraction - XPD. The work is especially focused on a method of ARXPS, which is used for the depth compositional analysis of sample surfaces. To obtain an information about the depth composition from the measured ARXPS spectra, a calculation software in the Matlab environment has been developed. The software has been tested both for simulated and real sample data. For an experimental implementation of these methods, a complete manipulation system has been developed. It ensures the transport of samples inside a vacuum apparatus and the experiment itself. The system is controlled mainly by a software and enables to run the experiments automatically.

Voronoi diagramy koulí v E3
Maňák, Martin ; Kolingerová, Ivana (advisor) ; Zemek, Josef (referee)
Voronoi diagrams (VD) describe spatial relationships among a given set of input sites. The family of VD for a set of points is a well-explored domain and e ective algorithms for their construction exist. Although the family of VD for a set of spheres has been known for many years, properties of these diagrams and algorithms for their construction are a relatively new thing. Their importance grows with the development in the area of molecular biology. The goal of this work is to survey the theory behind VD of spheres, implement one of the existing algorithms for their construction as a library and use the library on a real data, such as proteins.
