Data Mining with Python
Krestianková, Tamara ; Burgetová, Ivana (referee) ; Zendulka, Jaroslav (advisor)
This thesis deals with principles of data mining process, available Python packages for data mining and a demonstration of Python script capable of data analyisis focused on classification techniques. Created classifiers are able to classify subjects into two groups - healthy people and people suffering from Parkinson's disease - based on their biomedical vocal analysis data.

Automatic Largescale Processing of Testing Results
Klem, Richard ; Šnobl, Pavel (referee) ; Hruška, Tomáš (advisor)
This thesis deals with the issue of automated processing of large volumes of data in a relational database environment. The thesis focuses on the current situation in the Codasip company and solves the insufficiently fast implementation of materialized views updates. The result of the thesis is a draft to modify the current system. This draft successfully solves problems with slow data processing. The implemented solution then brought an average acceleration of the update of materialized views by 93 % and for some materialized views an acceleration of 99 %. This solution will help Codasip increase the efficiency of processor core development, as well as their other products. At the same time, this thesis can serve as a case study of optimizing slow database queries when processing large amounts of data.

Data processing from measurement on machine tools
Pokorný, Zdeněk ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
The Master’s thesis deals with the precision of machine tools, especially with the three-axis vertical milling machine. It is structurally divided into a theoretical and practical part. While the theoretical part focuses on problems of geometric errors and measuring devices, the practical one is devoted to the machine tool being tested. In this case, the data processing and the proposed statistical analysis are essential, and at the end of the thesis another possible way of developing the data processing is outlined.

Mobile device for acceleration measurement.
Jurníček, Jakub ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
Presented bachelor thesis deals with acceleration measurement and visualization. The acceleration is measured via two sensors perpendicular to each other. The measured acceleration value is displayed in real time, moreover the actual value is stored for furthe offline processing on PC. The ADXL320 module acts as a main sensor and two LED screens displays the actual value. The recorded data are transferred to permanent memory EEPROM. The entire device is operated by Atmel ATmega8 microprocessing unit which is connected to PC by common RS232 serial line. Further in the thesis there's presented suggestion of the final solution of the problem.

Big Data Processing in Industry 4.0
Stredánsky, Dávid ; Fajčík, Martin (referee) ; Smrž, Pavel (advisor)
Main goal of this thesis is to create application for industrial big data processing. Final application uses bearing vibration data. The application's design is inspired by Lambda architecture for big data processing. The application monitors data recieved from sensors in real time and enables periodic batch processing. Known methods from bearing condition monitoring, such as root mean square, deviation or skewness extraction are used in batch processing. Data prediction method Prophet is tested out in this thesis. Final web appli- cation is written in the Python language with the use of Dash framework and results are stored in MySQL database.

Experimental Determination of Mechanical Properties of Rubber Coupling segments
Zerzánek, Ondřej ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
Diploma thesis is dealing with testing of textile-rubber couplings by IGW company. Aim is to provide a high cyclic stress on a testing rig specially made for this test. The next task is to evaluate measured data in Matlab software. Then creating of user interface for displaying evaluated data, will be done. This interface will serve for testing in the future. There will be provided Ansys analysis and 3D scans of tested element. In the end all collected data for this thesis will be evaluated.
