Control of linear drive HIWIN by NI SoftMotion
Sabó, Marek ; Šubrt, Kamil (referee) ; Houška, Pavel (advisor)
This thesis deals with the control of HIWIN three-phase linear synchronous motor using NI SoftMotion and frequency inverter D1-N on the NI Compact RIO platform. In the introductory section is discussed the classification of linear motors, the principle of functionality of linear synchronous motors, described the fieldbus EtherCAT and the NI SoftMotion module. Further work is dedicated to the hardware used, its parameter, configuration and the regulation of drive control. The final part focuses on the design and implementation of axis control and movement accuracy verification.

The automatic self tuning system for seven-string guitars
Jeřábek, Vojtěch ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The thesis describes a realization of the automatic self tuning system for sevenstring guitars. There are comparisons of commercial and uncommercial solutions for six-string guitars. There is also evaluation of useful parts for seven-string guitars. Thesis contains a description of a requirements for individual parts and a control software with respect on real guitar properties and used computing algorithm. In the second part of thesis, there is a description of final system design and its realisation including the control software. This is also related with testing of the entire system.

Advanced Oracle Database Monitoring Tool
Mikulka, David ; Chmelař, Petr (referee) ; Kolář, Dušan (advisor)
This master's thesis describes possibilities of Oracle Database 10g and 11g monitoring. It let the reader know about practical tools for monitoring and describes the database's internal catalogs preserving statistics and the information about running database instances within history. Next, it describes design of an Oracle database monitoring tool, describtion of its implementation and at the end its evaluation and comparison with other similar applications.

Analysis of pitch perception depending on the spectrum
Slávik, Martin ; Indrák, Michal (referee) ; Jirásek, Ondřej (advisor)
This thesis is dealing with the research of the influence of individual harmonic components on the perception of sound height. As a part of the work has been made an internet questionnaire on a web address www.analyzavyšek.9e.cz, where individual respondents completed listening test compound of 46 samples. This experiment is based on semantic differential method. Individual samples are compound of sine wave – tone and examined sample, which respondents evaluates on three bipolar scales. The samples were either modelled by additive synthesis or modified sampled sounds of instruments. Individual samples were divided to four major groups and other minor groups for clarity. The purpose was to find which parts, combinations and harmonic components of sound and tone can affect perception of tone height.

Stress detection
Jindra, Jakub ; Vítek, Martin (referee) ; Němcová, Andrea (advisor)
Stress detection based on non-EEG physiological data can be useful for monitoring drivers, pilots, and also for monitoring of people in ordinary situation, where standard EEG monitoring is unsuitable. This work uses Non-EEG database freely available from Physionet. The database contains records of heart rate, saturation of blood oxygen, motion, a conductance of skin and temperature recorded for 3 type of stress alternated with relax state. Two final models were created in this thesis. First model for Binary classification stress/relax, second for classification of 4 different type of psychical state. Best results were reached using model created by decision tree algorithm with 8 features for binary classification and with 8 features for classification of 4 psychical state. Accuracy of final models is aproximately 95 % for binary model and 99 % for classification of 4 psychical state. All algorithms were implemented in Python.

Unbreakable Nightrunners
Tomanova, Karolina ; Šprincl, Petr (referee) ; Mazanec, Martin (advisor)
The video documentary Unbreakable Nightrunners deals with people around the artist, who documents what is happening in the group of which he is a part. The main actors live in the area and know each other from Elementary school. Half of the participants are still students and the other working individuals from different industries. Nightrunners are under 30 years old. Sometimes misunderstood by society and the surrounding area. The group of people she documents did not want to be like other people around. They didn't want to hang out and party. They have a common interest in cars and tuning. People with different views and styles, who always find a topic for conversation and space for joint activities have also a different philosophy of life, which could be summed up in the thesis that „life is a distinctive phenomenon that can not be reduced to mechanical events“. They help each other when something goes wrong, they are in good and bad times together. It documents all the events that the group creates, including ordinary meetings or interviews. It also reflects the fact that the group meets in one particular place and that is the gas station. The name Nightrunners is derived from a chat group on Facebook where they debate in various ways, agree on events, send funny videos and photos or spread new photos of cars and things they saw or were part of.
