Mobile applications development for remote control of instrumentation
Macek, Michal ; Křivík, Petr (referee) ; Frk, Martin (advisor)
The presented work describes the growing trend of using mobile devices to control laboratory instruments and displaying of measured data. The main objective is the application development for mobile devices, which will allow to remotely control and measure with laboratory instruments. The practical part is focused to programming mobile application which will be able by using the local network to connect multiple laboratory instruments, setting them for different types of measurements and then display measured data.

Use of mobile platforms Android for instruments control
Macek, Michal ; Šteffan, Pavel (referee) ; Frk, Martin (advisor)
The present work describes current trends and modern methods using mobile devices to operate laboratory equipment and subsequent measurements. The main objective is create application for mobile devices running on Android system, which will be remotely controlled and measured with instruments in the laboratory. Practical activities are focused on programming mobile application that can remotely laboratory device contact, set for different types of measurements supported device and then read the measurement data from the device to a mobile device.

Measuring System for Registration of Atmospheric and Switch Overvoltages in Electrical Power Network
Potáček, Lukáš ; Mišák,, Stanislav (referee) ; Kolcunova,, Iraida (referee) ; Baxant, Petr (advisor)
This thesis is oriented to a specific section of energetics concerned with detection and registration of time responses of fast overvoltages in high-voltage power networks. The first part of this text is information about measuring frequency response characteristics of CR-divider and calculation of typical signal distortion caused by transfer function of this divider. The design of anti-aliasing filter is also included. The second part of this thesis is oriented to selecting key features of a measuring instrument specialized for detecting and recording fast events in electrical power networks. A selection of optimal type of processor and also a choice of communication interfaces is included there as well. The last chapter prepares mathematical procedures for classification of typical fast events in electrical power network using artificial neural networks.

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.

Analysis of process for production of small plates
Talanda, Jiří ; Fiala, Alois (referee) ; Koška, Petr (advisor)
Theme of the Master’s thesis is analysis of process for production of small plates. Main parts of the thesis are analysis of the production process, process mapping, data capture, analysis of the data by Pareto analysis and find causes of nonconformities. Causes analysis is based on data analysis and process observation. It is divided to chapters by factors which are influencing the process. Optimization measures are designed with regard to their simplicity of realization and system in organization.

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.
