Re Vision
Švehla, Jakub ; Šrámek, Jan (referee) ; Kögler, Žaneta (advisor)
In form of 3D animation the thesis depicts the steps of mankind towards the expansion of civilization beyond planet Earth. Chronologically it exposes essential moments of technological development (in major) preceding the journey for the distant planets. Images of today's state of civilization are combined with constructions of former theoretical concepts and with fully fictitious elements to form visuals illustrating the roadmap to extraterrestrial expansion.

Unknown.mp3
Ščudla, Marek ; Doležel, Matěj (referee) ; Šrámek, Jan (advisor)
My bachelor thesis is my next music project, followed by instalation and merchandise. I was solving the questions about trends, genre and its boundaries. I was inspired by past and I was trying to fit it into contemporary context.

Design of optimization of extrusion process control tests
Pavlíková, Michaela ; Šrámek, Jan (referee) ; Maradová, Karla (advisor)
The master´s thesis is focused on the optimization of extrusion process control tests. The practise was performed at Fraenkiche CZ s.r.o., which is a company specialising in plastic tubes and components. The aim of the master´s thesis is to analyse the current state of the specific issue, systematically analyse the topic, statistically analyse and discuss the results and propose a new method of extrusion process control tests with my recommendation for practise. The introduction forms a preview into the quality management, plastic materials and processing of them. The practical part contains an analysis of the company and their production process. This information was helpful to the design of a list of control tests. With the help of basic quality tools, I prepared a new design of a list of control tests. The basic statistical processing showed an evaluation of finance savings. In the final part I evaluated the results and proposed several recommendations for improving current processes in the company.

Dream Journals
Silný, Ondřej ; Dočkal, Petr (referee) ; Šrámek, Jan (advisor)
Dream Journals is an art installation which is reflecting my dream world. Long term collected text notes are my thematic fragments for finding a found footage videos. The selection is based on visual similarities and atmosphere. These videos are combined with textures and found sounds. A spectator can't see clean digital image but he's looking through transparent material. The fact that video has not defined start and end amplifies dream aesthetics.

Minimizing errors in the alignment of the CAD model to the Coordinate Measuring Machine (CMM)
Miko, Jan ; Marek, Tomáš (referee) ; Šrámek, Jan (advisor)
This bachelor thesis is focused on the issue of alignment of measured data to nominal data in the field of metrology - measurement and evaluation of longitudinal dimensions, angles and tolerances of position and shape. The beginning of the work deals with the division of individual types of coordinate measuring machines and various data scanning technologies. The next section describes the measurement process, and especially in what ways the mea-surement can be performed. In the analysis of the use of methods for the alignment of nomi-nal data on a CAD model when measuring on a CMM, the individual methods of alignment are classified and described. The most common defects caused by alignment to a CAD mo-del are covered in the entire chapter, which describes what causes individual defects in most cases. The main part of the bachelor thesis is the study of measurements. In this study, the evaluation of outputs that were obtained after measuring and balancing the measured data on the CAD model of the reference part is processed. The alignment is performed by four diffe-rent methods. Subsequently, the individual methods were compared and the errors that occurred during the alignment were analyzed. In the last part of the work, a statistical evalu-ation of the measurement and determination of the measurement uncertainty is performed on the basis of the measured deviations of the positions of the assessed geometric elements, which occurred on the reference part. At the end of the thesis, the individual outputs that were obtained during the elaboration of the individual goals of the bachelor's thesis and the recommended methods of alignment for a specific application are evaluated.

Capability assessment of a optical measuring instrument
Slíž, Michal ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
The diploma thesis deals with the capability assessment of an optical coordinate measuring machine according to VDA 5. The capability assessment is an effective tool for deciding whether the evaluated measuring machine is capable for the intended use and under which conditions its use is possible. The theoretical part of the thesis is devoted to the analysis of coordinate measuring machines, with a closer focus on a subset of optical measuring machines and the analysis of their capability assessment procedures. In the practical part of the thesis, the selected procedure is applied on the specific measuring machine Micro-Vu Sol 311. The main contribution of this thesis is a description of the possibilities of the considered coordinate measuring machine for its further use in the educational process at the Faculty of Mechanical Engineering of Brno University of Technology.

Determining the measurement accuracy of a coordinate measuring machine Zeiss UPMC Carat
Kiška, Roman ; Jankových, Róbert (referee) ; Šrámek, Jan (advisor)
The aim of this diploma thesis is to create a comprehensive study of measurement accuracy of coordinate measuring machine (hereinafter CMM) Zeiss UPMC 850 Carat S-ACC (hereinafter Zeiss Carat) for the needs of the national metrological institute in Brno in accordance with ČSN EN ISO / IEC 17025 and the follow-up system standards of the ČSN EN ISO 10360 series. Additionally, it includes the creation of instructions for the calculation of measurement uncertainty, which will be put into effect in an accredited calibration laboratory. The first part of the work focuses on the description of the current state of knowledge and the definition of basic concepts in the field of metrology and accurate measurements on CMM. The second part describes the Zeiss Carat measuring machine, identifies the individual contributors to the resulting measurement uncertainty and defines the methodology for their quantification. The last part deals with the evaluation of calibration data and the calculation of the expanded measurement uncertainty of the Zeiss Carat instrument, which is used to quantify its accuracy.

Utilisation of Renishaw optical encoder system for sensors and comparators
Pavliš, Jakub ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
The diploma thesis deals with the description of selected optical systems in length metrology. The main benefit of this work is the design and implementation of a sensor with the VIONiCplus optical system and the application of this measuring system to length comparators. The work contains experimental verification of the use of an optical system with a resolution of 2.5 nm for sensors and length comparators with recommendations for practical use.
