Power LED Current Analyzer
Ryba, Ivan ; Vochyán,, Josef (referee) ; Šebesta, Jiří (advisor)
This thesis describes attributes of LED, especially high power LED. Evaluates posibilities of measuring the current passing through the high power LED device in the automotive industry. The basic requirement for the analyzer is adjusting it for the voltage and current through LEDs. Analyzer have to display the mean current and frequency. Additionally also minimum and maximum current, duty cycle and amplitude might me displayed. The central element of the device is ATmega16 microcontroller.

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.

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.

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.

Uncertainties of Accurate Length Measurement
Šrámek, Jan ; Brno), Václav Duchoň (ČMI (referee) ; Vdoleček, František (advisor)
This diploma thesis is supposed to inform readers interested in the distance measurements un-certainty on practical issues connected with the solving of these troubles when utilising a frequently used calibration method - the SIP distance meter. 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 (ČMI) as a sufficient guarantee for the hereinafter presented materials, both regarding the professional qualification and from the perspective of formal rightness of this thesis.

Physical measure by the mobile phone
MATYS, Jaroslav
This diploma thesis topic "Physical measure by the mobile phone" deals in theoretical part with term BYOD (Bring Your Own Device) and lesson 1:1, where is solving motivation of integrating devices into the lessons, what are the advantages and disadvatages of this problems and also what are the worries that pedagogues could have. Then thesis deals with equipment of mobile phones, principle of sensors functioning and in the end deals with searches of application for physical measuring by the mobile phones sensors, actual to the date of the writing this thesis. In the practical part thesis deals with comparison of values from aplication to the laboratory equipment. In the end deals with proposals of lessons activities with mobile applications.

Identify and evaluate the energy balance of small farms.
SEDLÁČEK, Radomír
The work deals with energy consumption in selected agricultural farms and their evaluation and comparison with norms. The theoretical part describes selected farms and production areas in which it is located. The practical part includes a methodological description of the measuring and calculation of the diesel oil consumption. Furthermore, comparison and evaluation of the results of the two farms with the directions.
