Real-Time Music Improvisation
Mareček, Daniel ; Glembek, Ondřej (referee) ; Fapšo, Michal (advisor)
This bachelor's thesis deals with development of a computer system, which is able to improvise music, based on user's playing a musical instrument connected to a computer via MIDI interface. According to my design, the main subsystem that generates music is based on a neural network. After successful implementation the system has been used in practice of music improvisation.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Realtime Weather in a Landscape Visualisation
Vlček, Adam ; Jošth, Radovan (referee) ; Seeman, Michal (advisor)
Thanks to the increasing computation power the complexity and dynamism of virtual reality is continuously improving. This work aims to examine influences of weather in a landscape and the means to simulate and dynamically visualize them in real time on the current personal computer hardware. The main goal is to find quick well looking approximations rather than a complex physically correct simulation. The work covers using modern programmable GPU not only for visualization but also as a powerful simulation instrument. The main topic is water movement in the terrain and its effects on it like erosion, snow melting and moisture impact on vegetation. This requires dynamic terrain texturing and algorithms supporting fast geometry and normals updates.

Detection and Recognition of Matrix Code in Real Time
Dobrovolný, Martin ; Juránková, Markéta (referee) ; Herout, Adam (advisor)
This work is dealing with detecting and recongnizing matrix codes. It is experimenting use of PCLines algorithm. PCLines is using Hough transform and parallel coordinates for fast detection of lines. Suggested algorithm with double use PCLines detects sets of parallels and problem with image distorted by with parallel projection is solved by cross-ratio equation. We did some optimizations for realtime running and created experimental implementation. Test results shows, that use PCLines one way to detect matrix codes.

Chord recognition
Soudek, Ondřej ; Glembek, Ondřej (referee) ; Černocký, Jan (advisor)
The goal of this bachelor thesis is to create an application, that will perform a real-time analysis of a signal from electric or acoustic guitar and will recognize a chord or tone, played by user. This document contains basics of music theory and the solution of the problem, as well as the results of testing.

Segmentwise Discrete Wavelet Transform
Průša, Zdeněk ; Vargic,, Radoslav (referee) ; Dr. Peter L. Sndergaard (referee) ; Rajmic, Pavel (advisor)
Dizertační práce se zabývá algoritmy SegDWT pro segmentový výpočet Diskrétní Waveletové Transformace – DWT jedno i vícedimenzionálních dat. Segmentovým výpočtem se rozumí způsob výpočtu waveletové analýzy a syntézy po nezávislých segmentech (blocích) s určitým překryvem tak, že nevznikají blokové artefakty. Analyzující část algoritmu pracuje na principu odstranění přesahu a produkuje vždy část waveletových koeficientů z waveletové transformace celého signálu, které mohou být následně libovolně zpracovány a podrobeny zpětné transformaci. Rekonstruované segmenty jsou pak skládány podle principu přičtení přesahu. Algoritmus SegDWT, ze kterého tato práce vychází, není v současné podobně přímo použitelný pro vícerozměrné signály. Tato práce obsahuje několik jeho modifikací a následné zobecnění pro vícerozměrné signály pomocí principu separability. Kromě toho je v práci představen algoritmus SegLWT, který myšlenku SegDWT přenáší na výpočet waveletové transformace pomocí nekauzálních struktur filtrů typu lifting.

MATLAB/Simulink, Real-Time simulation and control
Malík, Dalibor ; Chomát, Luděk (referee) ; Dvořáček, Martin (advisor)
This bachelor thesis provides information about a possibility of implementing the real-time, a serial line RS-232 and communication with a programmable controller (PLC) by Bernecker &Rainer (B & R) in MATLAB / Simulink evironment. Further, it provides information about options of creating a block in MATLAB / Simulink, modes of operation of the simulink and implementation of blocks to the blockset. In the proper communication with PLC the principle of PVI is described, the terminology connected with PVI is explained and setting and maintaining the communication between a source station and PLC is specified.

Firmware for the Robotic Vehicle
Otava, Lukáš ; Sojka,, Michal (referee) ; Kučera, Pavel (advisor)
This thesis is focused on a firmware for robotic vehicle based on the ARM Cortex-M3 architecture that is running a real-time operating system (RTOS). Theoretical part describes available solutions of embedded RTOS and concrete HW implementation of the robotic vehicle. There is also comparison of the three selected RTOS with their measurements. Result of this thesis is base firmware compounded by a program modules that controls HW parts. There is also a sample PC and firmware application that extends base firmware. This sample application is able to communicate with robotic vehicle, control wheel motion and measure process data.

Remote measuring systems and its utilization in practise
Kukla, Zdeněk ; Škoda, Jan (referee) ; Baxant, Petr (advisor)
This master’s thesis is dealing with remote measuring systems and their utilization in power engineering. In the first part there are described requirements on an autonomous measuring system and description of AMM and AMR systems. Communicating and data flows working on accurately defined communicating layers are also depicted in this part. The attention is devoted to the possibility of data processing and functions of devices offered by these attributes. In the following part there are described reasons for utilization of remote measuring systems in power engineering and the main advantages of connection of more devices into one unit. After finding of required parametres and functions of systems, a suggestion of terminal device is created in the same way. The suggestion is described in the measuring part with A/D converter, processing in microprocessor, measuring and evaluating alogorithms and attributes of communication of bus used. The last part is devoted to utilization of remote analysis in small power stations in dispersed production. Formation of deformation of voltage, harmonic analysis of signal and its application for data processing are described there. Described analysis was tested on data acquired from a cogeneration unit.

Theatre Puppets in Film
Volánková, Tereza ; BEČKA, Marek (advisor) ; KUBÍČEK, Jiří (referee)
This thesis mainly deals with the matters of transferring the experience with puppet theatre or theatre in general into the motion picture environment. Despite the fact that this is an actor's graduate work, it is trying to adopt all the main differences, and vice versa all the conformities between film and theatre from the author's and creator's point of view.
This work is divided into three parts. The first part focuses on comparing these two media (theatre and film) and tries to determine the terminology comprehensible by both, the theatre and the film community. It discusses some of the possible variations of film animation, always in relation to certain one, which is central to this work, which is real-time performed anti-illusive puppetry.
The second part describes the process of creating two specific events in the film directed by Tereza Volánková; authors own work, where the puppets are lead in this way.
The third part is a mere outline of a possible principle reversal, where the author uses some film practices in the theatre environment.
