Data acquisition - LabVIEW
Jeřábek, Martin ; Zůbek, Tomáš (referee) ; Šedivá, Soňa (advisor)
The main objective of this work is to create a program for automatic operation of measuring test track. The track is used for multi-hole velocity probes calibration. Normalized orifice plate is used as measurement standard. The program requires the user to enter certain information, which are not measured directly e.g. the values of measuring resistors, static air pressure. After entering this information, measurement can be started. The measurements are carried out simultaneously on the both flowmeters and on the thermomether Pt 100. The actual density of flowing medium is calculated from the measured temperature. Because the measurement is parallel, the calibrated flowmeter can be calibrated during the measurement.

Computer application for measuring parameters of network
Kolmačka, Tomáš ; Urban, František (referee) ; Grenar, David (advisor)
This bachelor’s thesis deals with the basic theory of network architecture TCP/IP which is used in practice and sets out the key parameters for data services and multimedia services using these networks. The thesis mainly deals with the methodology of measuring individual parameters and analyzes various methods of measurement and the accuracy of these methods. In the practical part of the bachelor's thesis a client-server mode application called Network Meter was programmed. This application allows the measurement of selected parameters between client and server using transport protocols TCP and UDP. When using TCP, the application can measure delay, data upload speed and data download speed. When using the second transport protocol, namely UDP, the application can measure jitter and packet loss. With the measuring application Network Meter test measurements were performed in the prepared home network. In the same network measurements were made using jPerf to compare the created application with other applications. In the comparison measurement download speed was measured.
