Features real-time operating system for LabVIEW
Válek, Petr ; Beneš, Petr (referee) ; Čejka, Miloslav (advisor)
This thesis deals with certain properties of real time operating systems (RTOS) Ardence PharLap ETS, WindRiver VxWorks and LabVIEW RT module. Three methodologies of RTOS quality comparison are proposed, two of which are practically tested with described experiments on CompactRIO hardware from NI. Furthermore, there is explained need for RTOS usage and experimental comparison of jitter error influence on total harmonic distortion THD defined by two definitions.

Frequency measurement
Milota, Martin ; Havlíková, Marie (referee) ; Čejka, Miloslav (advisor)
The topic of my dissertation is to verify the autocorrelation method for determining changes in frequency and other design software tools for measuring frequency. In my work I use outside the above-mentioned autocorrelation methods, Zero-crossing. The output is compared with the commercially designed software used and evaluate the results in terms of measurement uncertainties.

Data compression
Krejčí, Michal ; Havlíková, Marie (referee) ; Čejka, Miloslav (advisor)
This thesis deals with lossless and losing methods of data compressions and their possible applications in the measurement engineering. In the first part of the thesis there is a theoretical elaboration which informs the reader about the basic terminology, the reasons of data compression, the usage of data compression in standard practice and the division of compression algorithms. The practical part of thesis deals with the realization of the compress algorithms in Matlab and LabWindows/CVI.

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.
