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.

Tone and Chord Recognition as an Android Application
Kucharovič, Oliver ; Černocký, Jan (referee) ; Szőke, Igor (advisor)
The aim of this work is to recognize tones and chords on any musical instrument using the microphone on Android mobile devices. The app scans or records the sounds which are analyzed. It writes to a visual representation which is similar to the musical notation. The work describes the problems of recognition and the solution of the problem using fast Fourier transformation and analysis of the spectrum of volumes. Work describes the theory of music and the training of individual tones. The application was subjected to user tests and recognition accuracy tests. The conclusion includes tests results and statistics from the Google Play publication.

Real-Time Object Localization
Rydlo, Štěpán ; Chudý, Peter (referee) ; Kolář, Dušan (advisor)
This bachelor thesis purposes solution of a radio signal processing to determine actual receiver position on computers using software defined radio. The purpose of this thesis is to create and parallelize program to achieve real-time processing . To achieve real-time processing we will use GPU . This work contains a description of two independent possibilities of data transfer and processing .

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.

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.

Sample projects for operator panels
Urbánek, Matouš ; Šír, Michal (referee) ; Zezulka, František (advisor)
In this bachelor’s thesis will learn about the development of exemplary projects that are designed with fixed functionality for operator panels SIEMENS (BASIC, COMFORT, RT). For this task, I have a development environment TIA portal that brings together many software tools and programs. With which allowed me to create code for specific hardware, and communication with him, or in simulation mode to test the behavior of the application in a real environment. Code, on the PLC is required for the platform (PLC) S7-1200. It is modern and provides flexibility in making out our needs in automatik. The task is engaged, firstly synchronization solution PLC and HMI operator panel. Secondly resipes in these panels.

GNSS navigation prototype messages visualization
Homolka, Martin ; Frýza, Tomáš (referee) ; Povalač, Aleš (advisor)
The aim of this thesis is to graphically interpret navigation messages from a prototype of global navigation satellite system. The resulting application is implemented in Python programming language for Windows operating system and follows requests from researchers developing the prototype. Necessary terminology together with graphical user interface programming possibilities of object-oriented language Python is a base for theoretical background of this text. Practical part of this research describes a solution for receiving generated messages from the prototype as well as their storing and filtering into useful information. Further, the design of graphical user interface of the application for prototype interactions and other tools used for its configuration are included.

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.

Real Time Suppression of Atmospheric Turbulence
Macků, Jiří ; Orság, Filip (referee) ; Marvan, Aleš (advisor)
This paper deals with removing undesirable image deformations caused by turbulences of Earth's atmosphere. The goal is to design and implement algorithm for suppression of atmosphere turbulence in video sequences to use in long-distance camera monitoring system. This paper also focuses on optimization of existing algorithms for running in real-time. Algorithm will be implemented in C++ programming language with use of library for computer vision OpenCV.
