Image composition
Smital, Petr ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
This thesis deals with methods of improving the quality of image output of an electron microscope by composing consecutive frames. The thesis contains a brief description of an electron microscope and the problems that deteriorate its image quality, and three basic mathematical algorithms that can be used to remove them. These are the simple averaging method, the method of least squares and the method of vector space. For all of the methods, the thesis describes ways of their implementation, the possibilities of their use and their mutual comparison. This thesis also deals with the problem of so-called superresolution, i.e. exceeding the physical resolution of a sensor using the methods mentioned above, and the problem of electron beam centring.

Image analysis for correction of electron microscopes
Smital, Petr ; Schwarz, Daniel (referee) ; Kolář, Radim (advisor)
This thesis describes the physical nature of corrections of an electron microscope and mathematical methods of image processing required for their complete automation. The corrections include different types of focusing, astigmatism correction, electron beam centring, and image stabilisation. The mathematical methods described in this thesis include various methods of measuring focus and astigmatism, with and without using the Fourier transform, edge detection, histogram operations, and image registration, i.e. detection of spatial transformations in images. This thesis includes detailed descriptions of the mathematical methods, their evaluation using an “offline” application, descriptions of the algorithms of their implementation into an actual electron microscope and results of their testing on the actual electron microscope, in the form of a video footage grabbed from its control computer’s screen.

Quality plan of construction contract
Štrich, Petr ; Smital, Petr (referee) ; Tichý, Zdeněk (advisor)
The Bachelor thesis task is to set up a quality plan of a building order bespoke: additional building of a detached house Brno – Obřany. The history and present of quality planning and some concrete systems of quality planning are described in the theoretical part. Thereinafter are mentioned standards of series ISO 9000 and ISO 10005, which says what the quality plan should include. In the practical part, there is the analysis of the current position of the BDI Company and the suggestion of the changes inside this company that relate to quality planning. Furthermore the practical part contains elaborated control plan and the plan of a technical control bespoken.

Bypass - Zastávka u Brna
Čechová, Zuzana ; Smítal, Petr (referee) ; Holcner, Petr (advisor)
The aim of the bachelor’s thesis is a study of a traffic bypass around village Zastávka which is situated in South Moravia region approximately 20 km from city Brno to south-west. Main cause to create this solution is poor traffic situation. Village Zastavka is overloaded by traffic and this project would be beneficial by its effort to decrease amnout of traffic in the village center. There are two variants of a bypass. First one is connected to existing communications I/23 near to Rosice and goes to Tetcice, Babice u Rosic, Zbysov and Zakrany where its again connected to existing communications I/23. Second variant is way shorter and it is connected to oncoming bypass around Rosice and goes over Babicky les to existing communications I/23 where its connected close to Zakrany as well
