Psychogalvanometric measurement and biofeedback
Paulasová, Lenka ; Čmiel, Vratislav (referee) ; Hrozek, Jan (advisor)
This work deals with bio-feedback and the possibility of measuring changes in skin resistance for biofeedback. The Theoretic part is focused on the principle of biofeedback and its use. Next deals with the resistance of the skin, the changes depending on the emotions and the measurement this change . The practical part is devoted to the creation program for the use of skin resistance to change biofeedback in LabVIEW.

Leadership and management of personnel in construction company
Hegerová, Anežka ; Sláma, Lukáš (referee) ; Linkeschová, Dana (advisor)
This bachelor thesis deals with topics of leadership and staff management in the construction business. The purpose of the thesis is to analyze situation in the fields associated with problematics of Czech construction business. The theoretical part introduces concepts and theories related to said problematic. There are four hypotheses proposed in the practical part. The situation considering diversity, motivation, comunication and education is evaluated through survey. The outcome of this thesis are partial conclusions and suggestions derived from trends and experiences found through research. These conclusions and suggestions may be helpful for those holding leadership and employee management work positions in construction companies.

Phase shifted harmonic oscillators for practical education
Hudec, Marek ; Petržela, Jiří (referee) ; Šotner, Roman (advisor)
This thesis focuses on designing a laboratory preparation for the study of phase-shift oscillators. The first part of the thesis comprises a theoretical discussion regarding the given problem. The laboratory preparation will include two types of oscillator circuits. An operational amplifier will be used as the amplifying element together with an RC feedback loop in one type of circuit whilst the other type will consist of operational transconductance amplifier employed as inverting amplifiers and generating feedback. The second part of the thesis includes the actual design of the preparation. The design process covers construction stage of the preparation, calculation of the component parameters necessary for oscillation to occur, simulations of the individual circuits along with THD analysis as well as with analysis of manufacturing variances. The second part of the thesis also contains the design of a separate block of all-pass filter. The simulation results will be verified experimentally, on a printed circuit board. In the last part of the thesis, I will evaluate and intercompare the theoretical, simulation and practical results.

Design of audio power amplifier with Bluetooth connectivity
Bartoň, Jan ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
This bachelor‘s thesis deals with the task of designing an audio amplifier, operating in class D, with a nominal output power of 2 x 80 W with Bluetooth connectivity, supplemented by an equalizer and a state display. A power supply and a user interface are designed as well. At first, research regarding audio amplifiers is made, followed by a more thorough description of class D operating principles. Afterwards the actual synthesis of the desired amplifier is presented, followed by the power supply design procedure. The correctness of the synthesis is later verified by simulations in PSpice and LTSpice. Theoretical design is then practically built, and its parameters are confronted with expected values by measurements.

TTP protocol for managing hierarchy trees of RTCP feedback channel
Müller, Jakub ; Komosný, Dan (referee) ; Burget, Radim (advisor)
TTP protocol for managing hierarchy trees of the RTCP feedback channel represents the mechanism for transferring the big amount of data from end users via the “narrow” feedback channel. We are not speaking about thousands of users but about millions of users, which are using services like IPTV. The method of a data summarization is used for this purpose in selected network nodes. The summarized message is transferred and summarized again in higher levels of the hierarchical tree. Both methods allow reducing the amount of data and help to increase information content transferred via the feedback channel. Finding of the correct end user position in a network is also very important aspect. The user must be able to find the closest summarization node with this information and starts sending out the messages to this node for processing. There are several methods for constructing and managing the asynchronous feedback channel that are introduced in this work.

Strategy for Improvement of Training System of Company
Gazurová, Anna ; Kufa, Jan (referee) ; Mallya, Thaddeus (advisor)
This thesis focuses on problems related with new graduates at the „Department of New Employees Training“ of TŘINECKÉ ŽELEZÁRNY joint stock Company. The work evaluates to what extent the participants are satisfied with the training period, work of each mentor assigned to them and how they are involved in solving concreate tasks. Later suggestions are made on what measures should be taken to improve the program, for future participants to be satisfied.

Some specific of the communication in construction engineering
Kolomazníková, Alžběta ; Krňávková, Kateřina (referee) ; Linkeschová, Dana (advisor)
This diploma thesis is dedicated to communication in construction industry. The theoretical part is focused on definition of the terms like management, manager, communication and feedback. The aim of this thesis is to find out which ways of communication are construction companies using for sharing information. Diploma thesis find out if the employees have possibility to express their opinions. The thesis is dedicated to communication with construction workers and communication problems with them. Hypothesis are mentioned firstly, then they have been verified by questionnaire and interview. The result of this thesis is verification of hypothesis, that the face-to-face meeting is still most popular way of communication in construction companies. The employees receives all necessary information in sufficient amount at right time. Informal communication is the most common. Communication with construction workers is very specific. At the end I mentioned recommendation to improving communication in construction companies.
