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.

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.

Precise Detection of Musical Instrument Pitch
Hyrák, Jakub ; Skála, František (referee) ; Černocký, Jan (advisor)
The goal of this Bachelor's thesis is precise analyse of sound signal from musical instrument in real time and detect of fundamental tone. You can find a description of musical theory and methods, which solving this problem. The main part is a description of implementation of resulting application with using chosen method Constant Q transform. The final application may be used to tunning musical instruments.

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.

Tuning and testing of database systems for needs of digital archive SAFE III
Pobuda, Tomáš ; Chlapek, Dušan (advisor) ; Štrunc, Martin (referee)
Thesis deal with tuning of database Oracle, which is used by digital archive SAFE. In the concrete deal with setting parameters of database. It is divided to three parts. In first part it characterizes factors that influence performance of database. In second part it describes possibilities of tuning and setting Oracle database. In third part it is first introduced digital archive SAFE, after that it is chosen suitable testing tool for workload generation and described test scenarios and last are performed tests and compared results at different database database settings. Goal of thesis is description and trial tuning of Oracle database, which is used by digital archive SAFE. Other goal is test of files inserting into digital archive at different settings (saving to the database, on file system). These goals are achieved by testing tool workload generation and compare response time at different settings. Contribution of this thesis is above all trial of tuning Oracle database, which is used by digital archive SAFE. Document can be used like handbook for implementatory of tested implementation of digital archive SAFE.
