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.

Real Time operating system in LabVIEW - LabWINDOWS/CVI
Povolný, Petr ; Beneš, Petr (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.

Optimization of data transit in network
Řezáč, Michal ; Škorpil, Vladislav (referee) ; Kubánková, Anna (advisor)
This bachelor thesis is divided into two parts. The first part deals with and describes necessary teorethical units, together with analyse of ISP network and other input informations. These findings are further used in second part of bachelor thesis. The practical part dealt with testing of optimization mechanisms in the laboratory network. Thereafter has been done a wider tests of optimization mechanisms based on different ways of marking data streams and deploying these rules. The advantages and comparision of these methods were further evaluated.

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.

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.

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.

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.

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.
