Measurement setup for DC, AC and transient testing of two-ports
Káňa, Vojtěch ; Hruboš, Zdeněk (referee) ; Šotner, Roman (advisor)
This master´s thesis describes about automated measurements of two – ports of frequency, time and DC area. Gradually, there is elaborated several theoretical foundations dealing with this issue. For example, different types of buses, available programs and general theory of two – ports circuits. Also a method for solving and implementing a measuring device for communication between apparatuses and DUT is designed and described. In conclusion, the results and evaluation of measurement are processed.

Measurement of parameters of the aircraft hydraulic systems
Bareš, Josef ; Třetina, Karel (referee) ; Bencalík, Karol (advisor)
This thesis summarizes current knowledge of the parameters of hydraulic systems of aircraft. Attention is paid in particular to the continuity of information and the introduction of the reader to the parameters of hydraulic systems issue and the procedures for their measurement. In the introduction the thesis deals with the properties of hydraulic fluids and their influence on the operation of hydraulic systems. Subsequently methods and instruments that are used for laboratory measurement of the parameters of hydraulic fluid are described. Furthermore, the thesis moves on to the topic of hydraulic systems for aircraft, individual hydraulic devices and fluids that are used in the air and for general operation of hydraulic systems. At the end of the thesis a balance sheet is prepared over the selection of suitable laboratory equipment for the measurement of hydraulic fluid parameters.

Expressing uncertainty of accurate lenght measurement II
Šrámek, Jan ; Pernikář, Jiří (referee) ; Koška, Petr (advisor)
This diploma thesis is supposed to inform readers interested in the distance measurements uncertainty on practical issues connected with the solving of these troubles when utilising a frequently used calibration method - the Tesa NPL measure instrument. This measuring was implemented by the Czech Metrologic Institute, where the author works; therefore he could take advantage of his rich experience as well as experience of his superiors and colleagues. The author regards the national metrological institute (CMI) as a sufficient guarantee for the hereinafter presented materials, both regarding the professional qualification and from the perspective of formal rightness of this thesis.

Web interface for on-line administration of laboratory tasks
Belko, Jakub ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
The present work describes the current trends and e-learning methods using the Internet in the educational process on Czech and foreign universities. The main objective is to create a web interface for on-line administrations of laboratory tasks named "Laboratorě UETE". Practical work is focused on programming web applications and modules for management of instrumentation for laboratory protocols administration including implementation of the IP video cameras outputs and sensor atmospheric conditions. An integral part of this work is to create a module for simulation of physical quantities using commercially available software components based on client – server system.

Photopolymer length variation measurement
Novotný, Jan ; Vejlupek, Josef (referee) ; Matějásko, Michal (advisor)
This thesis deals with development of a special measuring device designed to measure changes in lenght of a photoactuation polymer. The length of a sample of the polymer shortens by tenths of a milimetre by being lit by intensive light. The sample has to be preloaded by force. The data are processed by designed electronics and recorded in a computer in a utility application, developed for this purpose. The thesis is realized in cooperation with the Centre of polymer systems of the Tomas Bata Univerzity in Zlín.

Communication of a Measuring Device with a Computer – Laboratory Experiments
Cigánek, Jan ; Frýza, Tomáš (referee) ; Jakubová, Ivana (advisor)
This project deals with the programme for automated measurement. Project describes main theory advices and possibilities of building programme with language C++. It shows complication in communication of PC with measurement devices and it describes programme commands. This work includes programme, solution, structure with examples of the algorithm and source code. The designed control programme has been applied for automated measurement of frequency characteristics of low-pass and high-pass filters with the analogue multiplier AD 633 using the programmable DC power supply Agilent E3631A, the digital multimeter Agilent 34411A or digital storage oscilloscope Tektronix TDS 1012 and generator Agilent 33220A.
