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.

Testing communication protocols using mobile technologies for the Internet of Things LTE-M and NB-IoT
Bartko, Samuel ; Dvořák, Radim (referee) ; Možný, Radek (advisor)
This thesis focuses on a comprehensive investigation and evaluation of the currently widespread communication protocols in the dynamically developing IoT sector (Internet of Things). With the proliferation of IoT, there is a need to create new technologies for efficient interconnection of hysical and digital worlds. The main objective of this work is to test and evaluate the suitability of use and optimal configuration of communication protocols in the context of the latest implementations of mobile technologies for IoT, namely LTE-M (Long-Term Evolution Machine Type Communication) and NB-IoT (Narrowband Internet of Things). This thesis investigates and evaluates the current communication protocols for the Internet of Things (IoT), focusing on LTE-M and NB-IoT. It includes a theoretical perspective on IoT, description of mobile technologies and analysis of protocols such as MQTT, CoAP and LwM2M. A practical part is devoted to testing and optimization of these protocols. The result of the work is providing\break a comprehensive overview and practical recommendations for use and configuration communication protocols in the framework of NB-IoT and LTE-M technologies.

Opensource firewall redundancy
Škurla, Tomáš ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
This diploma thesis deals with the comparison of different open-source firewalls from the perspective of high availability topology. The goal of the thesis is to determine the most suitable firewall for implementing a topology with high availability. The theoretical part deals with the explanation of the concepts of address translation, the operation of firewalls, and subsequently describes the protocols necessary for the implementation of high availability, followed by a description of the testing using GNS3. The practical part of the thesis describes the preparation of the laboratory environment, as well as the process of configuration and testing of the individual firewalls, followed by an evaluation based on the test results.

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 of a complex HIL simulator of car boot door
Obrtáč, Tomáš ; Krejčí, Petr (referee) ; Spáčil, Tomáš (advisor)
This thesis covers the development of complex HIL simulator for the fifth car door. The beginning of the thesis is dedicated to theoretical research in the area of In-the-Loop testing. Practical part describes development of HIL simulator complemented by power electronics part. A simulation environment Matlab/Simulink was used for control design and analysis. Before the beginning of the work was measured signal part of control unit and specific signal sequences were identified. The control was applied on sbRIO device from National Instruments company with the implementation of a model on FPGA. Specific requirements for sensing speed and generation of communication signals lead to creation of unique hardware for application needs. The result of the thesis is complex HIL simulator with intuitive GUI and possibility of simulations a wide range of DC motors.
