This diploma thesis deals with creation of a measuring application using optical sensor and robotic arm in the RobotStudio software. The literature review of the thesis describes the field of optical measuring and calibration. Furthermore, the thesis includes the process of creating a measuring application and outlining issue of calibration of individual parts. The work is supplemented by a demonstration of repeatability measurements and a description of possible errors that may occur if the robot is set incorrectly.

The main subject of this diploma’s thesis is the creation of laboratory task on the partial discharge. The thesis is made up of two parts: theoretical and practical. In the theoretical part there are information about partial discharge. One of them is classification partial discharge by type, effects of partial discharge in insulation systems, parameters to assess the quality of electrical insulation of power systems and measurement techniques. Further part is user’s manual for measurement instrument. In practical part is created laboratory task on problematic of the partial discharge measurement. It is demonstrative measure of partial discharge with the aim of understanding problematic of partial discharge, calibration and noise.

The main aim of this thesis is to design and build automatic calibration system for inertial measurement sensors. The calibration system is intended to support the development of devices with inertial measurement sensors. The great emphasis is placed on the configurability of system and for this reason all calculations are realized by Matlab system, which is well known by engineers. There is also presented design of inertial measurement unit, which is used as a~model sensor unit for calibration system development.

The aim of this work is description of a device developed at Brno University of Technology, Faculty of Civil Engineering, Institute of Geodesy for the purpose of absolute calibration of geodetic GNSS antennas. Thanks to calibration it is possible to remove systematic error of antenna's phase centre. The device consists of moveable arm and processing unit. The moveable arm is able to set up calibrated antenna to required azimuth and elevation angle. This work introduces the issue of absolute calibration, describes the moveable arm and the process of its assembling. Further, it defines geometrical parameters of moveable arm, describes their determination and their independent verification by geodetic method. Finally, the model of movement of antenna's reference point is described.

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.

This thesis deals with the aerodynamic analysis and shape modifications of the ARES aircraft. The analysis focuses on the evaluation lift, drag, and pitching moment coefficient, and further to identify the locations of stripping stream which is characterized by high drag. Before the analysis calibration of the CFD solver is done with the model, which has been measured in the wind tunnel. The aim of calibration is to verify the accuracy and veracity of the methodology used in mesh creation and calculated values. Calculated values are compared with measured data. The shape modifications of the aircraft are focused on conceptual design of the suction inlets for cooling radiators and engine aircraft. Aerodynamic analysis is performed with the modified model in order to determine the variation of lift, drag and pitching moment coefficient from its original configuration.

The presented work is concerning with ductile fracture problematic under monotonic loading which is result of gradual material degradation at large plastic deformation. At present, a large number of models, which calibration is not trivial, are used for its prediction. Ductile fracture mechanisms and cut-off region are described in the literature search part. Next, there is given a summary of criteria which are based on different approaches to ductile fracture. There were proposed and used KHPS and KHPS2 criteria within this PhD thesis. Procedure of assessment of the stress-strain curve and ductile fracture criteria calibration are described in last part of the literature search. A summary of tests, which were done in order to calibrate chosen criteria, is given in experimental part. Various stress states within broad range of stress triaxiality and Lode parameter were reached using these tests. Special type of specimen, by which very low stress triaxiality value is reached, was designed within this work. All specimens were made from the steel 12 050. Wrought rods of one melt with circular cross-section of 27 mm in diameter were used as semi-product. Calibration of chosen ductile fracture criteria was performed using foregoing tests. These criteria were implemented by author into explicit finite element software ABAQUS/Explicit using user subroutine VUMAT. Chosen criteria were used for simulation of multistep extrusion at which formation of internal central cracks occurs. These criteria were also used for simulation of cutting of circular cross-section rods. Results from simulation were compared to experiments which were done by industrial partner J-VST.
