Spatial Augmented Reality for Robotic Workplace
Štrof, Jakub ; Kapinus, Michal (referee) ; Materna, Zdeněk (advisor)
The focus of this work is to create projected user interface, which will complement AREditor, an application for robotic programming and also to calibrate Kinect and projector using existing calibration method. For calibration, I used the procam-calibration method, which uses projected Gray codes onto a chessboard to calculate calibration parameters. Thanks to it, virtual objects can be placed correctly into the real space. User interface was implemented using game engine Unity. By testing the interface, it was found that it helps the user to better grasp the relation between real and virtual space when placing virtual objects into the robotic workplace. It also raises user's awareness of the robot's movements when cooperating with it.

Prostředí pro automatizované testování síťových aplikací
Rozprým, Dalimil ; Setinský, Jiří (referee) ; Šišmiš, Lukáš (advisor)
The goal of this thesis is to create an environment supporting complex automation of network application testing. Testing of network applications poses some challenges not necessarily present in other software testing. The necessity of working with network architectures containing various interconnected devices is an example of those challenges. This text first outlines examples of the network applications which the environment is suited for, and then focuses on the envirnment itself. Subsequently, the technologies which the environment depends on, its design, details of its implementation and opportunities for extension are discussed. The environment for network application testing automation mainly focuses on solving challenges consisting of running the automation on GitLab CI/CD platform, distribution of data about testing environment to the tests themselves, and actually connecting the physical devices in testing netwrork. Due to the dynamic of new network application development and the introduction of new hardware into network architectures, the design of the environment focuses mainly on its extendability.

Development of rhythmic sense of preschool children in a heterogeneous group
Šumpíková, Magdaléna ; Kmentová, Milena (advisor) ; Hons, Marie (referee)
The bachelor's thesis deals with the development of rhythmic sense in preschool children in an age-heterogeneous group. A field study was carried out in a nursery school to investigate the development of rhythmic sense in individual children over a period of three months. The thesis is divided into two main parts: theoretical and practical. In the theoretical part, the thesis focuses on musical rhythm and its components, the sense of rhythm and how to develop rhythmic sense, and the issue of rhythmic sense diagnosis. The practical part describes the characteristics of the researched group, the course and results of the field research framed by the individual diagnosis of rhythmic sense of children in kindergarten. The aim of the research is to verify the validity of the existing test of rhythmic sense according to Miloš Kodejšeka with a new musical component (songs) in children aged 3-5, for whom the existing test has not been used before. This test proved to be almost functional in the research, except for one item and part of the non-continuous scoring scale. During the research period, the rhythmic sense shown by the pre- and post-test improved in almost all children.

Design and implementation of a platform for control LLC-type inverter with a wide input supply voltage range using a FPGA circuit
Pokorný, Ondřej ; Levek, Vladimír (referee) ; Prokop, Roman (advisor)
This master’s thesis deals with the emulation of LLC converter control with a wide input voltage range using a created emulation platform. The first part of this work is focused on the design of resonant converters with a wide input voltage range. Based on theoretical knowledge, an adjustment of the emulation LLC converter is made. The converter modification is concluded with a simulation, where the correctness of the design and the fulfillment of the ZVS parameter in the entire input voltage range are verified. In the next part of the work, an analysis of the control issues of resonant converters, more precisely LLC type resonant converters, is carried out. The acquired knowledge is used for the design of a new emulation platform, which will serve for the emulation of LLC converter control with a wide input voltage range. The last part of the work is the creation of an emulation program for FPGA in SystemVerilog language. The work is concluded by verifying the functionality of the emulation on physical hardware.

Proposal of the thermo-vacuum chamber for CubeSat testing
Jalůvka, Jiří ; Mašek, Jakub (referee) ; Lazar, Václav (advisor)
The thesis focuses on the development of thermo-vacuum chambers for CubeSat measurements. It presents a survey of thermo-vacuum chambers in the Czech Republic. Furthermore, it defines the requirements for CubeSat thermo-vacuum testing. Based on these requirements, a comparison is made between the existing chamber at the Aerospace Institute of VUT and several proposed solutions for individual challenges. Specifically, three innovative approaches to chamber entry, thermal systems, and satellite fixation within the chamber are suggested. The thesis not only describes the desired configuration of a thermovacuum chamber with all its systems but also provides concrete proposals for optimizing the existing chamber at the Aerospace Institute to enable successful CubeSat testing.

Trends in Recruitment and Employee Selection
ŽALUDOVÁ, Natálie
This bachelor thesis focuses on the issue of recruitment and selection of employees, especially on the identification of current trends and the following implementation of these trends into practical use. The aim of the bachelor thesis is to identify trends in recruitment and selection and to propose the implementation of these trends in corporate human resource management and then also to provide a complete analysis of the recruitment process. The thesis first focuses on understanding the issues through a literature search to study relevant topics such as recruitment and selection, defining old and modern methods or the potential of using artificial intelligence in the industry. This theoretical knowledge is then applied in the practical part, where through qualitative research it was possible to carry out a complete analysis of the recruitment process of the selected position and to find the deficiency that is eliminated through the created proposal for improvement. The conclusion of the thesis includes the new element created for testing the candidate as well as recommendations for possible improvements to increase the efficiency of the company's recruitment process, all in line with current trends in recruitment and selection.

Design and implementation of VoIP protocols tester
Polášek, Jakub ; Číka, Petr (referee) ; Krajsa, Ondřej (advisor)
This paper deals with ways and means of testing SIP or IAX2 based equipment and protocols itselfs. I analyse terminology and methodology for benchmarking of proxy and registrar servers as it was described in documents RFC 7501 and RFC 7502 from organization IETF. In the practical part is described the tester realization programmed in PHP programming language witch will use described methodology. Aplication is available in web based interface.

HIL test stand for universal electronic control units
Zouhar, Štěpán ; Musil, Filip (referee) ; Brablc, Martin (advisor)
This diploma thesis is focused on testing of Electronic Control Units, especially functional testing in which hardware and software is verified and also Model in the Loop, Software in the Loop, Processor in the Loop and Hardware in the Loop testing methods. Within practical part of this thesis testing stand for functional test of the ECU was developed and manufactured. It is connected to PC via Input/Output card, testing is controlled by MATLAB script. Whole process of testing is automated from initial upload of testing firmware to tested ECU over all phases of test up to bootloader flashing. Hardware in the Loop test was also created, in which ECU works as controller and DC motor is simulated in real time with PC in MATLAB environment.
