Electronic tunable harmonic oscillator
Veselý, Jiří ; Jeřábek, Jan (referee) ; Šotner, Roman (advisor)
This masters project describes properties and primary parameters of active function blocks (OPA, VCA, OTA, CFA, CC) usable in construction of harmonic oscillators. Basic principles of harmonic generators, especially feedback oscillators, are introduced. In next section are presented five particular schematics of harmonic tuned oscillators. For this oscillators are indicated basic formulas, essential qualities performed by simulations and results of sensitivity and tolerance analysis. In the last part of diploma thesis there are selected three circuits which are made and their features are measured.

Measurement of customer content of quality management
Plánková, Barbora ; Knoflíček, Radek (referee) ; Rozehnalová, Jana (advisor)
The bachelor thesis deals with the measurement of customer satisfaction in the field of quality management. The theoretical part contains customer satisfaction and the methodology of measuring customer satisfaction is analyzed. The practical part describes current measurement of customer satisfaction in the company Tawesco s.r.o., Kopřivnice. The aim of this work is to evaluate the current situation and propose recommendations for improving quality management in the area of customer satisfaction, which is processed as follows. This bachelor thesis is mainly focused on the modification of the formal side of the questionnaire, recommendations for increasing the response rate of respondents and streamlining the survey process. There are developed reccomendations for changes based on the analysis of the current companies questionnaire and comparability of data obtained from respondents from the years 2017-2019. Particular recommendations should lead to more accurate information obtained from customers and it ensures more effective implementation of improvements and subsequent increase of customer satisfaction.

Better Chaperone Bounds Using 3D Sensors
Tinka, Jan ; Beran, Vítězslav (referee) ; Najman, Pavel (advisor)
Room-scale tracking encourages users to move more freely and even walk. Even though there has been much research on making the limited physical workspace feel larger in the VR, these approaches have their limitations and require certain conditions to be met. This thesis proposes an alternative approach to the conventional play-area boundaries of high-end VR products such as the HTC Vive and Oculus Rift which are set by the user in a 2-D fashion as a means of enhance workspace utilization. A 3-D scanner is used to make a 3-D point-cloud model of the play area's surroundings. This model is then used to detect collisions and provide feedback to the user. Evaluation based on user tests showed that this approach can be useful, is well accepted by users and might be worth further research.

Automatic Assignment of Student Projects in Python
Kyseľ, Juraj ; Škoda, Petr (referee) ; Smrž, Pavel (advisor)
This work focuses on automatic evaluation of student codes in Python programming language. Emphasis is placed primarily on feedback, to guide students in the correct Python code writing practices. In the practical part, the information obtained is used to design a system that alerts beginning programmers to errors and tries to teach them the right structures in the form of python idioms. Further, the thesis describes individual parts of the system, its inputs and outputs. As a case study, the system was put in place to support the teaching of the subject Scripting Languages at the FIT VUT in Brno in the academic year 2017/2018. The thesis summarizes the experience of this deployment and evaluates the advantages and problems of the processed solution.

Inverters for lighting units with LEDs
Zuber, Zalán ; Feiler, Zdeněk (referee) ; Klíma, Bohumil (advisor)
The master‘s thesis deals with DC/DC converters for power LED diodes. Gives an overview of the field of LED lighting technology, analyzes various types of converters and shows their principle of operation. Furthermore presents some possible circuit designs for three different voltage levels and the calculations for each part. As an approval of their functionality the results of their measurements are plotted followed by the data evaluation.

EEG Biofeedback Human Brain - Computer Interface
Kněžík, Jan ; Kořenek, Jan (referee) ; Marušinec, Jaromír (advisor)
This master thesis dwells on EEGbiofeedback (also called Neurofeedback) interface of human brain and the computer and its concrete realization in Java programming language. This system is founded on the basis of the computer, which is accomplishing biological feedback (biofeedback) and the electroencephalography (EEG) by helping that state's scanning of user's brain is realized. By this way is possible to practise the human brain effectively to achieve better concentration, the elimination of sleeping and learning deficiency. Hereafter is the suggestion of direction control of computer mouse by EEG device incorporated, which makes it possible for the man to regulate the direction of the cursor's movement on the screen by the frequency of brain's oscillation. The motivation for solution of this problem is the effort to help to handicapped people to communicate with surrounding world. The introduction of this paper contains the basic facts about human brain, electroencephalography and EEG biofeedback. The following chapters dwell on the specification of claims to developed application, its suggestion and description of actual realization. The final part relates to the BCI (Brain-Computer Interface) systems and suggestion of computer's control by EEGappliance with evaluation of attained results.

Participativní leadership ve vybraném sektoru
Dudová, Klára
The bachelor thesis deals with participative leadership and its implementation in the selected sector. The first part of thesis consists of the literature and focus mainly on the definition of participative leadership, its practices, meanings, but also risks. Based on the established theory, an analytical part of the thesis is created, with is indicated by a description of the selected secondary sector, which deals with manufacturing and industry. Subsequently, a sample of data obtained through a questionnaire survey is described and analyzed. Based on the obtained data, recommendations are made that contribute to the improvement of the implementation of participative leadership procedures in companies in the selected sector.

Communication methods of teachers at lower secondary school in relation to dialogic teaching
Votický, Petr ; Duschinská, Karolina (advisor) ; High, Radka (referee)
The diploma thesis analyzes the level of some communication methods of teachers at the second level of elementary school, which should lead to improved and more balanced mutual communication. The essence and goal of the work is to examine the presence of dialogic teaching of selected teachers. The work will offer an interesting comparison of theories with real findings. In the theoretical part, I describe and reflect on the use of communication forms using elements of dialogic teaching. I introduce and explain the elements that, according to the expert, lead to stimulation, engagement of students' thinking, which influence their learning and understanding. Dialogic teaching differs from the classic IRF structure in the teacher-student approach using question work and feedback in the learning process. I am looking for some answers to the questions of what communication factors influence student learning through teacher communication. I describe theoretical principles, selected examples, methods and their subsequent results when used in practice or research. At the same time, I present the advantages and reasons for use. In the practical part, through qualitative research, I analyze audio recordings from classes and interviews with teachers and students. I distinguished between open and closed...
