Tyre Temper. Meauserement on Moving Vehicle with Use of Infrared Pyromether OS100
Morávek, David ; Rasch, František (referee) ; Blaťák, Ondřej (advisor)
Bc. David Morávek Tyre temperature measurement on moving vehicle with of infrared pyrometer OS100 MT, IAE, 2008, page 70, picture 41 Problemacy of recording the temperature and tyre pressure on driven car is processed in this diploma work. Suitable measuring chain was set up. Censor holders for this type of measurement were designed and produced. Driving exams and tests are depicted in this work, too. We came to the conclusion that tyre temperature depends on lengthways and transverse acceleration of the car and also on it’s load.

Documentation of Balkónová and Balkóta passages in Býčí skála cave
Velecká, Kateřina ; Kuruc, Michal (referee) ; Kratochvíl, Radim (advisor)
The bachelor thesis deals with documentation of the part of cave system Býčí skála, namely of the passages Balkónová chodba, Balkóta and part of the passage Kóta 314 in the form of a ground plan, extended longitudinal section and cross sections in the scale of 1:250. The thesis contains a short description of the locality, steps from recognition and completion of the existing measuring network to a detailed survey and creating of the final map in the JTSK coordinate system and the Bpv height system. For the detailed measurement was used a special speleological measuring method utilizing a device DistoX2 with a tablet and the program TopoDroid for creation of the measuring sketch.

Measurement and evaluation of flows in sewer networks
Haška, Aleš ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
Measuring flow rate, water surface and rainfall are the crucial inputs for the calibration of the hydraulic model. This bachelor’s thesis presents mathematical models and measuring devices for the sewer networks. This thesis summarises the measuring devices that are currently available and used on the sewer network. Furthermore, theory of random and systematic errors is discussed. In the second section, this theory is implemented in the chosen area for the sewer network in Znojmo. On the 9. 9. 2020, three ultrasonic measuring devices (type ISCO 2150 with AV sensor) and one device for measuring water surface (type IJINUS) were installed in this area. This thesis provides continuous measurements which are then applied for the calibration of the hydraulic model. On completion of this thesis it is necessary to continue to calibrate and verify the model in order to increase accuracy and be more precise.

Coaxial multiplexer for automatic measurement of AC current
Boštík, Ondřej ; Klusáček, Stanislav (referee) ; Havlíková, Marie (advisor)
Master’s thesis in the theoretical part deals with literature review on the topic of measurement errors and measurement uncertainties. The practical part deals with the simulation of additional capacitive and resistive load on the amplitude and phase error during shunts based measurement. For this simulation is used mathematical apparatus of cascade matrix of two-ports and their connections. For the actual simulation is used script for MATLAB. Furthermore, the work deals with the design of voltage follower to eliminate simulated errors and its practical realization. The last part deals with the design of the coaxial multiplexer for switching current shunts developed in the Czech Metrological Institute in Brno.

The expression of the accuracy of the gauge and measurement
Svobodová, Helena ; Koška, Petr (referee) ; Pernikář, Jiří (advisor)
The bachelor thesis deals with the issue of measurement, accuracy of measuring instruments and their expressing. It outlines the legislative basis of metrology in the Czech Republic and interprets the definitions of basic terms used in metrology. These definitions are listed in the new edition of International dictionary of metrology (VIM 3:2007). It specifies and exemplifies measurement errors and presents possibilities of their elimination. Further, it describes a simple way of measurement uncertainty determination. The aim of this thesis is to explain the issue in a way that it is understandable and can be applicable for the common metrology practice.

Non-contact Temperature Measurement
Lata, Miroslav ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The object of this bachelor thesis was to create a study of development non-contact temperature measurement and show methods of measurement in infra-red radiation area. The beginning of this work is focused on major notions and definitions necessary to introduce non-contact temperature measurement topic. Other interest of this work was to mention possible error rate of measurement, it’s reasons then name some ways of calibration of a measuring equipment with it’s reasons too. Last part of this thesis was focused on a practical using of these measuring devices.

IR camera data processing
Malík, Dalibor ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
The aim of this master’s thesis is to give information about the thermo camera measurement with error minimization. The basic concepts of thermography are explained with an implementation of postprocesing technique which uses graphically modified thermogram back projected to the scene. This is closely related to the scene design, calibration of thermal camera with projector, image rectification, thermogram processing with highlighting of interesting information and implementation of control elements as the user interface. The results obtained are analyzed and re-evaluated.

Device Location in Wireless Network
Szabó, Peter ; Malinka, Kamil (referee) ; Kačic, Matej (advisor)
This thesis deals with the issue of locating devices in wireless networks. It takes existing solutions as example and extends them using additional approaches. This thesis designs and describes the implementation of a prototype of a new proprietary indoor localization system used for locating devices within a WiFi network. In the final part of the thesis the testing of this system is described and its results are analysed and compared with another localization systems based on similar technologies.
