Abstract:
The thesis is deal with measuring the temperature dependence of dynamic viscosity and the calculation of measurement uncertainties. The thesis writes up the physical nature of viscosity and rheological properties. Next it is write up an overview of possible methods for measuring viscosity of liquids and overview of methods for measuring the density of liquids. An important chapter is the statistical evaluation of measured data represented mainly measurement uncertainties. In the practical part of the work is done workplace for measure the temperature dependence of dynamic viscosity. It is used two methods of measuring viscosity of liquids and two samples of liquids. Finally is done statistical evaluations of measurement. Based on the calculated measurement uncertainty measurement methods are compared.

Abstract:
This diploma thesis is dealing with pressure measurement. It describes instruments dedicated to purpose - pressure gauges. Basic of correct pressure measurement is knowledge of behaviour of used pressure gauge. This knowledge is acquired by calibration. With calibration is associated also analysis of errors and uncertainty of measurement and creation of calibration list. Calibration takes place on model workspace pressure measuring in laboratory.

Abstract:
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.

Abstract:
The Master’s thesis deals with the precision of machine tools, especially with the three-axis vertical milling machine. It is structurally divided into a theoretical and practical part. While the theoretical part focuses on problems of geometric errors and measuring devices, the practical one is devoted to the machine tool being tested. In this case, the data processing and the proposed statistical analysis are essential, and at the end of the thesis another possible way of developing the data processing is outlined.

Abstract:
The diploma thesis consists of a new design of a controlling procedure for a plastic component of a tank. Its theoretical part deals with the potential sources of errors and uncertainties arising from the measuring itself. It also deals with the characteristics of available CMM devices and includes an analysis of the methods assessing the acceptability of the measurement plan. The practical part analyses systematically the current state and proposes a new solution using a program created using a coordinate machine. A comparison of both variants is presented as an output of the thesis.

Abstract:
In recent years, there has been a strong need for the design of integrated  circuits showing low power consumption. It is possible to create intentionally approximate circuits which don't fully implement the specified logic behaviour, but exhibit improvements in term of area, delay and power consumption. These circuits can be used in many error resilient applications, especially in signal and image processing, computer graphics, computer vision and machine learning. This work describes an evolutionary approach to approximate design of arithmetic circuits and other more complex systems. This text presents a parallel calculation of a fitness function. The proposed method accelerated evaluation of 8-bit approximate multiplier 170 times in comparison with the common version. Evolved approximate circuits were used in different types of edge detectors.

Abstract:
The goal of this thesis is create measuring station of resolver with using Analog Devices AD2S1210. The measuring station is based on the Atmel ATmega16 microprocesor and programmed in the C language. The measuring plant of resolvers to detection fault per one revolution is developed with industrial cooperation. The measuring station is made for a mobile use with onboard Pb accu. Measuring station will be used as a service device or in the manufacturing for setting the right angle of resolver on the engine. For the faults debugging of resolvers cables and other faults with the signal chain between the resolver and AD2S1210 is possible to show the SIN and COS signals on the external scope.
