Automation of the calibration process
Mařas, Michael ; Šedivá, Soňa (referee) ; Beneš, Petr (advisor)
This master thesis deals with the automation of the calibration process at the workplace for calibration of electronic power meters and the description of the method of evaluation of calibration results. The paper analyses the calibration workstation and the manual method of calibration performed by the calibration laboratory staff. Furthermore, proposals for automating the manual method of calibration and a description of the implementation of a program for automating this process are given. Subsequently, the uncertainty analysis is described in the paper. In this section, the uncertainty analysis according to the GUM method and the subsequent calculation of these uncertainties are presented. The correctness of the calculation of uncertainties according to the GUM method is verified by the Monte Carlo method. In the last part of the work, the method of evaluation of the calibration results according to ILAC-G8:09/2019 is described and the form of the calibration protocol is described.

A popular fairy tale as a theme referring to the sources and strength of it's author
FEJTKOVÁ, Tereza
The work deals with the search for the strength and resources of man in his favourite fairy tale story. The theoretical part deals with the fairy tale in general, its characteristics and structure. It also summarizes the importance of the psychological effect of the fairy tale on man. The application of fairy tale themes in art therapy work is described in more detail, and the background of projective-intervention therapy is mentioned.The practical part focuses on the search for strength and resources in the theme of My Favourite Fairy Tale. Seven case studies are presented, which are developed using a qualitative research method. In line with the focus of the art therapy study, the respondents' artifacts are interpreted in detail. The findings from the practical part of the thesis, together with the theoretical aspects, are compared in the discussion and the results are summarised in the conclusion of the thesis.

Energy supply of the complex Technicka 2
Buráň, Petr ; Lisý, Martin (referee) ; Pospíšil, Jiří (advisor)
The theme of this master thesis is „Energy supply to the site Technická 2“. This thesis is divided into several parts. First we will get in touch with concept of combined heat and power and also with principle of photovoltaic electricity production. We will continue with description of site before and after reconstruction. Then we will follow with analyze the effect of reconstruction on energy consumption. In the end we will make some suggestions for using the local source of heat and electricity in Faculty of mechanical engineering, Brno university of technology. All suggestions will be analyzed from energy and economic point of view.

Determination of sound source orientation from multichannel audiosignal
Sumtsov, Artem ; Ripel, Tomáš (referee) ; Krejsa, Jiří (advisor)
The goal of this thesis was a research on appropriate methods of determination of sound source orientation and consequently its processing. This thesis describes subsequently four methonds of determination of signal delays between different channels. Each of these methods is evaluated with respect to suitability, usability, error rate and sensibility. In the next part the geometrical model for determination of the sound source orientation is described. Experimental solutions are processed for the situation with three microphones. Calculations are done in Matlab.

Acoustic emissions of buildings
Smažinka, Josef ; Uher, Pavel (referee) ; Rubinová, Olga (advisor)
The diploma thesis deals with acoustics with the main focus on acoustic emissions of buildings. The first part of the thesis aims to familiarize the reader with the field of acoustics as a whole. They will learn the basic concepts, quantities and relations that exist in acoustics. In the second part I focus specifically on the sources of noise in buildings and their surroundings, how can excessive noise affect health, what standards must be met and how to prevent excessive noise. The last part is devoted to practical measurements in the field, which is focused on real sources of noise in the city of Brno. The aim of this measurement is to compare the noise generated by buildings with other noises in the urban environment.

Uninterruptible Supply of the Hospital Information System
Kučera, Josef ; Sekora, Jiří (referee) ; Fedra, Petr (advisor)
This bachelor thesis is focused on the proposal for an appropriate source of uninterruptible power supply (UPS) to the school server UBMI where is currently installed HIS (hospital information system) CLINICOM Corporate SMS. UPS should have ensure the protection of data being unfinished, secure off site and to inform the line voltage failure.

Controlled high voltage source
Chloupek, Jiří ; Hanák, Pavel (referee) ; Koton, Jaroslav (advisor)
The aim of this master thesis is to design a high voltage source for the generation of bipolar pulses, which are suitable for the process of reversible and irreversible electroporation. Further design is electronic control. The first part of the thesis analyzes the theoretical knowledge about the process of electroporation, the second part describes the principles of realization of such sources, the next part deals with the design of the source and its control. The penultimate part is a description of the user manual and the last part is dedicated to the measurement.

Proposal for heating of family house
Pavlíček, Michal ; Špiláček, Michal (referee) ; Hrnčířová, Michaela (advisor)
Family houses heating, depending on economic factors, is currently highly discussed topic. My work evaluates the possibility of heating such houses. The technical possibilities of model building and design of optimal heating sources are taken into account. The link of investment requirements and their return is also observed.

Evaluation of entropy sources in common computers
Bafrnec, Matúš ; Zeman, Václav (referee) ; Burda, Karel (advisor)
This thesis is focused on entropy sources and their evaluation. It includes a brief introduction to the information theory, description of entropy sources, their parameters and characteristics and methods of evaluation based on the NIST organisation standard SP 800-90B. The following part of the thesis is dedicated to the description of two created programs and evaluation and comparison of entropy sources. Additionally, the last part describes the usage of hash functions in association with entropy sources.
