Zjišťování přítomnosti rizikových faktorů práce a pracovního prostředí
Toláš, Oldřich
The final thesis is focused on risk factors occurring in the working environment. The theoretical part of the thesis defines what is risk and risk factors of work - how it is evaluated, measured and how employees are protected by legislation. The practical part of the thesis describes measurements, especially air quality, in the working environment of members of the Customs Administration of the Czech Republic.

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.

Serviceability Evaluation of historical concrete floor slab
Dudek, Matěj ; Žítt, Petr (referee) ; Schmid, Pavel (advisor)
The master’s thesis is focused on serviceability evaluation of historical concrete floor slab realized in the third decade of the 20th century. The assessment of structural performance is based on the results of load testing in situ. The thesis defines contemporary load testing requirements followed by the specifications of measuring instruments and the possibilities of displacement measurements during load testing. In addition, it includes structural and historical investigation of the building, methodology and data evaluation of the load testing. Finally, the theoretical computer simulation of executed load testing is run by using software determined for nonlinear finite elements analysis.

Network connection application of measurement instruments in technical diagnostics
Gőtz, Lukáš ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This labor discusses with the possibilities of using a network connection devices in measurement technology from Agilent. It deals with the theoretical description of the different ways of measuring devices connected to computer networks and their use in laboratory teaching. Practical work is focused on creating automated utilities for selected tasks in the laboratory diagnosis of electrical materials in the software Agilent VEE Pro. The work is a detailed description of the labs in terms of setting and controlling the basic parameters created by the application. Installation and configuration of software and hardware communication tools are summarized in the brochure "How to handle a remote connection of measuring instruments over the Internet."
