Retrieval study of hands gestures recognizing methods captured with camera
Rybnikář, Petr ; Kroupa, Jiří (referee) ; Kovář, Jiří (advisor)
The aim of this bachelor thesis was to get acquainted with basis methods of of image processing, which can be used for recognizing hands gestures captured with camera. After that choose one method, describe it in detail and implement the method.In the first part of this theses few methods for image processing are described. In the second part Level set method is choosen and described in more detail, this method is later implemented in MATLAB R2019a. In the last chapter results of implementation are analyzed and evaluated.

Implementation of presentational device with Raspberry Pi
Beránek, Ondřej ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
This thesis describes the design and subsequent implementation of a presentational device with Raspberry Pi using free software. The theoretical part of this thesis includes an analysis of available commercial solutions, specification of requirements, testing free operating systems and assessment of their suitability for the purpose. The practical part of this thesis is focused on the implementation of a presentational device with the most suitable free system and on the test of this final solution. The aim of the thesis is to create a maintenance-free presentational device with easy remote access.

Design of datalogger for production machine
Gazda, Ondřej ; Kovář, Jiří (referee) ; Andrš, Ondřej (advisor)
This thesis describes the design of the data datalogger for collecting the operating data of the machine tool. Dataloggers and data acquisition systems are used in scientific research as well as in the industry for recording and analyzing large amounts of data. The control unit of the proposed system is the National Instruments CompactRIO platform. System software is created in the LabVIEW programming environment and uses both the FPGA circuit and the real-time processor of the control unit. Measured data are stored on the unit and in the database. The measurement status is reported via email.

Aplikace evolučního algoritmu na optimalizační úlohu vibračního generátoru
Nguyen, Manh Thanh ; Kovář, Jiří (referee) ; Hadaš, Zdeněk (advisor)
This thesis will deal with the use of artificial intelligence methods for solving optimization problems with multiple variables. A theorethical part presents problems of global optimization and overview of solution methods. For practical reasons, special attention is paid to evolutionary algorithms. The subject of optimization itself is energy harvester based on a piezoelectric effect. Its nature and modeling is devoted to one chapter. A part of the thesis is the implementation of the SOMA algorithm for finding the optimal parameters of the generator for maximum performance.

Coherent dusty and gaseous structures near the Galactic center
Štofanová, Lýdia ; Karas, Vladimír (advisor) ; Kovář, Jiří (referee)
Sagittarius A*, a compact source in the centre of the Milky Way, is the nearest supermassive black hole (SMBH) in our cosmic neighbourhood, where various astrophysical processes take place. In consequence, variety of structures emerge near the Galactic centre and bow shocks that are closely studied in this work represent an example of them. The introductory part of this thesis is a brief review of the history of the Galactic centre research and its discovery in radio wavelengths. The main body of the thesis is focused on a simplified model of the bow- shock structures that are generated by stars moving supersonically with respect to the ambient medium. We discuss how these structures vary along the orbit. To this end, we consider four different models: (a) without the presence of any gaseous medium emerging from or accreting onto the SMBH, (b) taking an outflow from the SMBH into account, (c) the case of an inflow onto the SMBH, and finally (d) the combined model involving both an outflow and an inflow at the same time. We discuss symmetries of each model (or lack of them) and we find that the model considering the ambient medium at rest appears symmetrical with respect to the pericentre passage. The combined model manifests itself as the most asymmetrical one of them all. We show profiles for the...

Server application for distributed computing
Svozílek, Marek ; Andrš, Ondřej (referee) ; Kovář, Jiří (advisor)
This diploma thesis deals with the realization of a server application for distributed calculations programmed on .NET platform and in C # language in development environment Visual Studio 2015. The diploma thesis is divided into the theoretical and practical part. In the theoretical part, the thesis deals with technologies, which are needed for implementation of the application. Here is how each technology is used and set up to serve the purpose of the master's thesis. In the theoretical part, functionality is shown in the examples. The practical part describes the layout of the application and the functionality of the individual part of the application. The architecture of each part of the application is presented in the UML class diagram.
