Light wavelength measurement module
Matoušek, Vojtěch ; Štohl, Radek (referee) ; Havránek, Zdeněk (advisor)
Measurement of the wavelength of light source by means of dual-wavelenght photodiode sensor is easy and fast. From the dependencies of the measured voltages corresponding to generated photocurrents of both elements of dual-wavelength sensor it can be calculated the information about wavelenght and intensity of the measured light source. Evaluation, displaying on LCD and sendind of measured information to PC are ensured with microcontroller from the AVR family – ATMega32. One part of the project is also visualization software for PC. Measurement module can be powered with wall socket power adaptor or with battery.

Remote data downloading from automotive digital tachograph
Matoušek, Vojtěch ; Macho, Tomáš (referee) ; Petyovský, Petr (advisor)
Thesis deals with device firmware design located in lorry, which provides remote access to vehicle digital tachograph data according to valid EU legislation. The result of this work is a system, which downloads digital data from digital tachograph and save them on remote server. The system for remote data downloading from automotive digital tachograph consists of three kinds of applications: server application, user application and firmware for communication device. Communication between applications uses encrypted TCP connection and own special designed messages.

Automatic music transcription
Matoušek, Vojtěch ; Richter, Miloslav (referee) ; Petyovský, Petr (advisor)
This article deals with the automatic music transcription into the music notation by Fourier transform with logarithmic scale and constant Q transform. The result of this work is application, which converts the music records, in the WAVE music le, into the MIDI le. Then MIDI le can convert into the music notation by appropriate tool. Algorithm for automatic music transcription can converts polyphonic music record, where plays more tones at one time, with simple rhythm.

CNC - design and contrlol
Matoušek, Vojtěch ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
My task was to build a smaller structure triaxial CNC milling. I designed electronics for motion control. The main part is the implementation of the control unit, which will provide control of the machine. The work includes the complete design, PCB design and program description for the uP ARM. The unit can work independently as well as hardware interpolator connected to the PC.

Self-proclaimed political pundits in the age of social media
Matoušek, Vojtěch ; Lupač, Petr (advisor) ; Sládek, Jan (referee)
(in English): This thesis studies political pundits in the US who utilise YouTube as their main channel of communication. In particular, it studies a possible impact which political pundits in the non-traditional media might have in polarising the public and this in comparison with political pundits in the traditional media. The goal of this thesis is to better understand what makes the YouTube based political pundits different from their traditional news counterparts and which underlying messages we can find in their news reporting. The work uses the theoretical background of the echo chamber theory to utilise the content analysis methods in three major steps. First, categories are being established for predetermined dimensions using an exploratory content analysis of the biggest three traditional news outlets in the US. Using the established dimensions and categories, a quantitative content analysis is conducted on seven chosen non-tradition news outlets based exclusively on YouTube. To further explore the way by means of which these outlets present their messages, a qualitative content analysis is done on selected stories. It has been found that non-traditional media outlets are in general more inclined to talk about policy than traditional news outlets. It also has been found that YouTube based...

Automatic Music Transcription
Matoušek, Vojtěch
This article deals with the automatic music transcription into the music notation by short Fourier transform with logarithmic scale. The result of this work is application, which converts the music records, in the wave file, into the music notation. But the algorithm can work only with music records, where plays one tone at one time.
