Real Time operating system in LabVIEW - LabWINDOWS/CVI
Povolný, Petr ; Bejček, Ludvík (referee) ; Čejka, Miloslav (advisor)
The aim of this theses is to make user acquinted with programming of real time applications in LabVIEW and LabWINDOWS/CVI environment. The introduction outlines basic properties and parametres of operating systems. Key requirements of real time operating systems are discussed here. Their basic concept is described, focusing on VxWorks operating system and comparison with deterministic properties of common MS Windows operating system. In the second part, there is a brief specification of LabVIEW and LabWINDOWS/CVI environment and a description of real time applications built up in these environments. The final part of this theses proposes a system for analog data acquisition for checking on deterministic properties of real time application and applications built up on MS Windows.

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.

Video mixer/translator for web-based videoconference system
Hutar, Jan ; Balík, Miroslav (referee) ; Číka, Petr (advisor)
Bachelor s thesis specialises in a basic description, comparing and processing of video standards H.264 and VP8 in real time. Particularly it concerns a support of videoconfe- rence systems working with those mutually incompatible standards. The work enquires and tests two most considerable software devices convenient with basic requirements for working with video in real time and available with LGLP licence respectively FFmpeg and GStreamer. The thesis suggests practice video mix implementation of data input and the way of code translation into required outgoing stream. FFmpeg tool has been used for realization and message of mixer/translator and simple interface has been established available from web browser with assistance of HTML, PHP and Javascript.

Interactive Document Sharing
Jóba, Viktor ; Jurzykowski, Michal (referee) ; Mlích, Jozef (advisor)
The thesis deals with the real-time sharing and editing of text documents in the network. The synchronization of the document content for all users in the shared session is ensured by the algorithm of operational transformations. This method is described in the thesis in detail. The outcome of the thesis is a simple text editor that communicates over the network using the extended version of the XMPP protocol. One of the users creates a document sharing session in the editor and invites other users to cooperate on the rich text document that can be saved in HTML or exported into PDF.

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.

The Turbocharger Model for Real-Time Computation
Hána, Michal ; Beran, Martin (referee) ; Svída, David (advisor)
The thesis deals with the creation of a mathematical model of a turbocharger, which is intended for integration into an electronic control unit and therefore for real-time operation. The model can be used to determine parameters that may or may not be measured. These are mainly air and exhaust gas temperatures and pressures at the compressor and turbine outlet. The model can be used in the electronic control unit as a feedforward or feedback control system. The beginning of the thesis contains a research on turbocharging and the emphasis is placed on exhaust turbochargers. Turbocharger characteristics, which are crucial for the model itself, are described in detail. The possibilities of testing turbochargers, in which their characteristics are measured, are briefly described. Due to the importance of turbocharger characteristics for the mathematical model, two options for their incorporation into the model are proposed. One way is in the form of lookup tables and the other way is in the form of interpolation and extrapolation relations or so-called curve fitting. The developed model is largely based on the thermodynamic relations that describe the turbocharger behaviour. Therefore, the individual T-s diagrams for both compressor and turbine and the thermodynamic relations based on these diagrams are given. The graphical programming environment Matlab Simulink is used to build the model. The developed model is then tested and validated on data obtained from WLTC cycle measurement. In the end the real-time operation of the model is verified.

Automatic Rail Traffic Controller
Štětina, Jan ; Babilon, Robert (advisor) ; Foniok, Jan (referee)
Organizing traffic on the railroad is quite a difficult task even if there is an elaborate train timetable present. In practice it is allways neccessary to adaptively react to current situation - whether there is a delay, a traffic closure or a special train. Aim of this project is to design and implement an application for use on average personal computer, that would for given railroad area, timetable and the current time design a plan of train journeys so that the disruption of traffic continuity is minimal. The application should base on the plan not only on the timetable, but mostly on current situation in the area.

Presentations Making Blender add-on
Telmanik, Ronald ; Milet, Tomáš (referee) ; Chlubna, Tomáš (advisor)
Cieľom tejto práce je vytvoriť nástroj, ktorý umožní používateľom programu Blender vytvoriť prezentáciu vo forme snímkov. Tento proces je zvyčajne časovo náročný spôsobené najme komplexnosťou program Blender. Preto na uľahčenie tohto problém je vytvorené rozšírenie pre program Blender. Toto rozšírenie implementuje sadu nástrojov, ktoré uľahčia tvorbu a neskôr aj samotnú prezentáciu v reálnom čase. Finálny zdrojový kód rozšírenia je voľne dostupný na platforme GitHub.
