Wernischaz
Janyšová, Lenka ; PROVAZNÍK, Jaroslav (advisor) ; BERGMAN, Aleš (referee)
The bachelor thesis records a staging process heading towards creation of the theatre performance Wernischaz. It describes nearly yearlong activity of a student group studying at a high school level of a gymnasium that were striving to discover poetics of Ivan Wernisch’s texts.
The thesis contents information about the group, passages on Wernisch’s work and experimentations with his texts, followed by information about the realization and the presentation of the project.

Functional morphology of myocardium
Vebr, Pavel ; Žurmanová, Jitka (advisor) ; Míčová, Petra (referee)
The thesis is a literary review summarizing current knowledge about the ultrastructure of myocardium in the overall context of the development and anatomy of the heart. The first part of the study is a summary of heart anatomy and its embryonic development, with emphasis on the morphology of cardiomyocytes. The state of inner cytoarchitecture of myocardial cells and the quality of inter-cellular connection reflects the functionality of the heart. Location and condition of cell compartments reflect the overall condition of the cell. The following part is devoted to the basic microscopic analysis methods suitable for research ultrastructure of cardiac cells. The outcome of this work is a comprehensive overview of the organization of remarkable morphological formations in cardiomyocyte, possible changes in ultrastructure in context of physiological conditions and comparison of microscopic methods with regard to their use in research of cardiomyocytes ultrastructure.

Study of physical properties of nanostructures using magneto-optical techniques
Beran, Lukáš ; Veis, Martin (advisor) ; Mistrík, Jan (referee)
Magneto-optical spectroscopy methods are used to study magnetic pro- perties of materials down to nanometer dimensions due to its high sensiti- vity and non-contact nature. This requires sophisticated experimental setup, advanced technical equipment and precise optical components arrangement. This thesis describes the basic physical principles of magneto-optical Kerr spectroscopy. On the basis of these principles is designed and developed a new, much simpler experimental setup with crossed polarizers. This arran- gement has the same order of sensitivity and accuracy of measurement as commonly used modulation techniques to which it is compared in this work. Finally, this arrangement is applied to the study magneto-optical properties of selected magnetic structures and these properties are discussed. 1

Modern flow visualization techniques
Pištěcká, Kateřina ; Koutník, Tomáš (referee) ; Popela, Robert (advisor)
The subject of this bachelor thesis is an overview of the flow visualization methods applied in the wind tunnels and fly tests. An overview of flow visualization methods is presented in the first part of the work. The particular methods are presented and evaluated with respect of its complexity, requirements on the instrumentation and expanses. The pros and cons are mentioned for each method finally. The second part of the work deals with selection of the flow visualization method suitable for application in the wind tunnel of the Aeronautical department of the VUT Brno.

Problems in machining of titanium alloys
Drábek, Tomáš ; Slaný, Martin (referee) ; Sedlák, Josef (advisor)
The theoretical part of the thesis contains a brief overview of some experimental methods that are used in machining technologies. The experimental part at first elaborates on the analysis of two titanium alloys. The actual experiment, which consists of milling of the two aforementioned materials with the use of several tools and holders, is then described. It was conducted in collaboration with the company Frentech Aerospace s.r.o. When milling, forces were measured with piezoelectric dynamometer. Further, the analysis of acquired data that is followed with discussion about its main findings, is provided. The conclusion of the thesis deals with the found facts corresponding with the information obtained by analysis of materials. The main results arise out of the comparison of used combinations of tools and holders for milling of material Ti-Al6-V4, observation of impact of particular factors on measured force, or out of different values of measured forces when milling two given materials.

Realization of Educational Problem on Experimental Apparatus for Measurement of Gear Efficiency
Runštuk, Jiří ; Mazůrek, Ivan (referee) ; Klapka, Milan (advisor)
This diploma thesis is focused on the implementation of the educational role of the experimental station for measuring the effectiveness of gears. The proposed laboratory task "Experimental measurement of the effectiveness of gears" is intended to familiarize students with the basic principles of gears and especially highlight the issue of the effectiveness of gears. In this presented thesis, it is also suggested the possibility of expanding the educational use of the experimental station. This extension deals with vibration diagnostics of frequencies of gears.

Flow visualization methods
Ďurdina, Lukáš ; Jedelský, Jan (referee) ; Lízal, František (advisor)
ĎURDINA, L. Flow visualization methods. Brno: Brno University of Technology, Faculty of Mechanical Engineering, 2010. 45 p. Thesis supervisor Ing. František Lízal. This thesis deals with fluid flow visualization methods with respect to their practical application possibilities. Chronological description of the historically valuable visualization experiments emphasises the role of visualization in the experimental fluid mechanics. A brief characteristic of the flow field contains mathematical description of the objects, which can be visualized. Visualization methods are divided into experimental and computer aided methods. Individual methods are ordered subsequently beginning with those with lowest requirements for equipment to the more sophisticated methods. Various techniques, which provide qualitative and quantitative description of the tested gas or liquid flow, are described. The overview for the choice of methods for various applications sums up the important facts from previous chapters. Description of a simple helium bubble flow visualization experiment realized in a lab can be found at the end of the thesis.
