Measurements of small flow rates
Lorenc, Dominik ; Šedivá, Soňa (referee) ; Mancl, Vlastimil (advisor)
The thesis deals with the extension of the laboratory fixtures with a~measuring track designed for the measurement of small fluid flows, on which the thermal flowmeter is tested. The used calibration methods are examined and the track is then subsequently constructed. A~measurement operating program is also developed to set the measurement parameters and to store the measurement data in the required format. The parameters and characteristics of the reference scale used and the thermal flowmeter provided are then measured on the constructed track. The measurement results are presented and the uncertainties of the selected flow rates are determined.

Extending the Parking and Boxes Laboratory Models for Connectivity to Decentralized Periphery
Mancl, Vlastimil ; Arm, Jakub (referee) ; Jirgl, Miroslav (advisor)
This bachelor’s thesis is about the description and connection of box conveyor and parking lot laboratory models to decentralized periphery made by SIEMENS with the usage of PROFIBUS DP communication standard. In order to do so, programs for controlling models were made in three different programming languages: LAD, STL and GRAPH. The programs were developed in engineering software SIMATIC STEP 7, created especially for programming PLCs made by SIEMENS company. Another part of this thesis is about the visualisation of laboratory models, made in WinCC software. The models were rated in terms of functionality and usability for study purposes. The results of this thesis are programes made for controlling the models with working visualisation and a possibility of connecting these models to decentralized peripheries.

Drivers for optical spectral analyzer.
Fišer, Michal ; Pikula, Stanislav (referee) ; Mancl, Vlastimil (advisor)
This bachelor thesis describes the application for the control of the optical spectrum analyzer Bristol Instruments 771B-NIR. The purpose of the application is to measure the spectrum of optical signal and wavelength. Theoretical knowledge of wavelength and spectrum measurement and the optical spectral analyzers are summarized in the theoretical part. The practical part focused on the realization of measurement application and library of functions that were created in the LabVIEW environment and the SCPI standard commands are used to control the instrument. Both the application and the library of functions are inspired by the factory-supplied NuVIEW interface.

The Hefaistos System
Mancl, Vlastimil ; Beneš, Petr (referee) ; Pikula, Stanislav (advisor)
This master's thesis describes functionality and principle of the Hefaistos measurement system, which is fully automated and modular. Its purpose is to measure frequency responses of materials and its temperature dependence. The thesis describes all the necessary parts of the modular measurement system. Main part of this system is the control application programmed in LabVIEW software environment. Another necessary parts are impedance analyzers for acquiring frequency dependencies and heating chambers for heating measured materials. The control application ensures hardware synchronization between impedance analyzers and heating chambers. Together they create the Hefaistos system. Modularity of the system means that a user may choose which instrument combination will be used. The system offers choice between three impedance analyzers Agilent 4294A, Wayne Kerr 6520B and HIOKI 3532 LCR Hi-Tester and two heating chambers AOIP GEMINI 700 LRI and AOIP HYPERION. Possibilities of the Hefaistos system are demonstrated on the results of an example measurement.

Tool for visualization and listening of vibration signals
Slavov, Jan ; Mancl, Vlastimil (referee) ; Čala, Martin (advisor)
This bachelor thesis deals with the development of a tool for visualization and listening of vibrational signals. The aim of the work is to find out the possibilities of the LabVIEW development environment in the area for which the application is intended, to further evaluate similar programs offered on the market and to create an application that will allow the user basic signal processing. The application also allows you to work with the myDAQ device and listen to signals through speakers, during which it will display the current playback position.

Measuring parameters of large-area capacitive sensors in touch screens
Baďo, Martin ; Mancl, Vlastimil (referee) ; Beneš, Petr (advisor)
This thesis studies characteristics and technologies used in capacitive sensors. For the purpose of automatic testing of sensors was selected and assembled device LowRider CNC V3. Tested sensors are from materials: silver nanowires and copper electrodes. Device during automatic tests was causing certain level of electromagnetic or electrostatic interference on sensors. Copper electrode sensor responded more significantly to touch but also interference, in comparison with silver nanowires sensor. Results of thesis more closely describe responses by sensors to touch and advantages or disadvantages of automatic testing.

Optimization of electrostatic simulation by utilization of distribution equations with emphasis on design of capacitance sensors of inhomogeneity distance
Mancl, V. ; Beneš, P.
This paper deals with the problem of optimizing the simulation of electrostatic fields with a focus on electrode setup simulations for capacitive sensor design. Several simulations were performed in Ansys electronics desktop software in Maxwell 2D and 3D module. The simulations were carried out on a sensor model with parallel plates, between which the movable inhomogeneity was placed. In the simulation, the inhomogeneity was modeled as an solid object. The proposed optimization consisted in replacing the inhomogeneity as an object by the equation of permittivity distribution in the space between the plates of the capacitor. The obtained dependences of the capacitance on the position of the inhomogeneity of the two models were compared together. Also the time required to complete the simulation was discussed. In addition to evaluating the advantages and disadvantages of the two modelling approaches, the paper describes a method for simulating a continuous gradient distribution of inhomogeneity permittivity.
