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.

Analysis of Trench Insulated Gate Bipolar Transistors
Karlovský, Juraj ; Polčák, Josef (referee) ; Bábor, Petr (advisor)
This thesis is focused on the selection and optimalization of suitable analytical methods for study of TIGBT (Trench Insulated Gate Bipolar Transistor) structures with a use of methods, that depict material composition of the studied sample. The theoretical part contain explana-tions of the analytical methods used for measurements and basic principle of operation of an TIGBT transistor. The practical part contain the methodic of measurements and the evaluation of the obtained data and design of optimal procedures in done experiments.

Switched power source for electroplating
Janků, Roman ; Minárik, Vladimír (referee) ; Červinka, Dalibor (advisor)
The thesis deals with the switching source for electroplating. The theoretical principles of galvanizing, the optimal technological process and a list of most commonly used metals are described. There is also a list of well-known producers, and a description of their resources for electroplating, which have the same output parameters. In the second part of the work there is an introduction of the already-completed school source 2000A/20V, major technical imperfections is solved there. There is also proposition of technical layout made in 3D AutoCAD. Finally, there is an economic analysis of the production costs of the source and a research in suitable suppliers of components and materials. The thesis contains an estimate of the selling and total price compared with competition.
