Master thesis is focused on creating graphical user interface for the sensorical system based on Phase-OTDR. Theoretical part describes optical fibers, explains the principle of Bragg gratings, their production and their use in sensors. Methods of optical fiber attenuation and phase OTDR measurement are also described. Other part is focused on LabVIEW programming software and utilization of sensorical system and its components. Practical part deals with the user interface itself, which consists of two tabs. The first tab is designed for evaluation and display of measured data. The second tab is used to control and set up system components. Both of these tabs are further subdivided into other subtabs. Regarding the conclusion, further development of the program and options of hardware replacement for improving this sensorical system in the future will be discussed.

This master thesis focuses on the testing of the combustion equipment and the wood fuel combustion process. The aim of the thesis is to get acquainted with this issue and to analyze solutions for monitoring and control of heat source parameters according to valid legislation. The result of this thesis is the realization and verification of the software design of the combustion test system using the NI LabVIEW development environment.

The diploma thesis is focused on the innovation of partially user-unsuitable software which is used in the CVVOZE short-circuit laboratory for the evaluation of testing of switching and protection devices. The introductory part of the work presents a technical laboratory, which is used for research and development in the field of electrical devices with possibility of testing of short circuits and over-currents. At the first part of thesis, there is made a description of the technical laboratory. The following past is a chapter with basic introduction of tested devices and standard testing conditions of electrical devices in the laboratory. Then following a description of the original evaluation software is made and its shortcomings are pointed out. The practical part is devoted to the creating in LabVIEW, implementation and verification of the functionality of the new evaluation software.

Dielektrické materiály jsou použivány v elektronice i v elektrotechnice. Jako jejich základní vlastnost může považovat změnu jejich charakteristik během jejich životnosti. Změny jsou způsobeny namáhaním materiálu vyvolané elektrickými či teplotími vlivy. Možnost jak určit průběh jejich charakteristik v závislosti na čase je měření proudu během aplikování elektrického napětí na materiál. Tyto experimenty vědci z LEMD provaděli ručně, tento postup ale není přílíš učinný pro vysokofrekvenční signály nebo pro experimenty s dlouhou periodou. Hlavním cílem této práce bylo vytvořit aplikaci v LabVIEW k ovládaní měřícího přístroje Keithley (generátor napětí) a k automatickému získavání měřených hodnot v pikoampérech. Tato aplikace nabízí uživateli různé funkce: - Zadání vystupního napětí. - Vyběr typu průběhu. - Definování délky periody. - Ovládaní přístroje. - Měření proudu, ukládaní dat do souboru vhodného pro jiné aplikace (textový soubor). - Analýzu naměřených dat.

The virtual laboratory is divided into two groups. The first group is comprised of a virtual laboratory for simulation. It is mostly used for presentation and demonstration purposes. It is not necessary to install complicated and expensive software for their use. The second group of the virtual laboratory is a long distance measure. Real systems are measured with the help of this laboratory. The advantage of long distance measuring is that data from the measurements are saved directly onto the personal computer and they can be immediately evaluated. In this project the procedure for creating a virtual instrument for long distance measuring is described in the LabVIEW program. LabVIEW is a graphic developmental environment, for the measuring and analysis of data.

This master’s thesis contains complete design of the complex measuring system for temperature, pressure and flow. Objects of measuring are pressure in rabbit’s heart ventricle, flow of the saline through the heart and the temperatures of physiological solution. Work is interested in programming of microcontroller and program for LabVIEW environment, which is used to view and export relevant data related to measuring. Text also contains technical documentation of functional sample of measuring system.

The focus of this diploma thesis is on methods for the subjective assessment of sound quality according to recommandations given by International Telecommunication Union ITU. The thesis is thematically divided into four parts. The first part is an interpretation of methods based on internationally accepted standards (method of small impairments, MUSHRA, general methods). The second part describes the functional blocks of application developed for this thesis in LabVIEW enviroment. Next part explains its practical application, especially its running possibilities. The last part describes a listening experiment, aim of which was to verify the application's features and to compare the results of the subjective method used in the experiment with the results of the objective method PEAQ.

In this paper is discussed impulse testing at high voltage switchgear. It focused on practical methodics of measuring, theoretical knowledge and technical terms. Further is discussed a parts of switchgear UniGear ZS1, which is most often equipment to measure. It also dealing with own measurements, process of measuring and wiring diagram. As next step, is perform trial testing with Dr Strauss system and digital osciloskope. Based on trial test, it choose digital scope and create application in in the program LabVIEW12 and debugging workstation at technical laboratory in ABB.

This master’s thesis is focusing on compensation of reactive power, especially on creating demonstrative model of static var compensation unit (SVC). Main topic of thesis is to apply this device for fast balancing dynamic conversions of recieved reactive power. In theoretical part is described suitable method for determination of instantaneous power. Next, there is basic description of all means used for compensation of reactive power and detailed description of the SVC compensator. Practical part includes design of compensation unit and control program in LabVIEW. The pq theory is implemented for detection instantaneous power. The results of validating functionality of compensator are presented in the last part of thesis.

This thesis describes the development of control applications for the deposition machine and mass spectrometer. Thesis describes operation principles of both devices and their hardware specifications. Thesis also describes the design of developed applications. Functionality was tested on series of real measurements.
