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.

Program Equipment for Computer Support of Measurement
Krontorád, Jakub ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
This Bachelor thesis is concerned with the program equipment for computer support of measurement. It treats of the software support of measurement as one of the useful methods of the automatization of measurement and also discusses the date computing as same as the information processing. The Bachelor thesis labours some chosen and more important programs used for the engineering practice and mentions some others opportunities of measurement which are possible and available. At the close of this work there is summary of advantages of computer measurements and you can also find there a comparison of some programs depending on demands on hardware and application.

Model of Orifice Flowmeter
Dvořáček, Tomáš ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The aim of this Bachelor thesis is to make the orifice flowmeter accessible for laboratory tuition. The introduction of this Bachelor thesis explains and describes the issues of measuring of liquid flow rate. The individual measurement methods and the types of flowmeter sensors are introduced. The practical section of the Bachelor thesis consists of a proposal and an actual realisation of a model of an orifice flowmeter with a computer supported evaluation.

Temperature Measurement in Technical Diagnostics
Szmek, Tomáš ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The purpose of this bachelor’s thesis is to familiarize a reader with possibilities of temperature measurement along with constructions and functions of particular measuring instruments and to present their positive and negative aspects. Both basic contact thermometers used in common life and complex systems (thermovision) employed in the most demanding industrial application are described here. The thesis depicts temperature as a diagnostic value according to which the causes of machinery failures are easily detected and subsequent accidents prevented.

Control of higher order plant
Zvara, Pavel ; Janečka, Jan (referee) ; Davidová, Olga (advisor)
This work is dedicated to simplifying transfers of proportional and integral non-oscillatory plant of higher-order. A simplification was done in different ways and designed controller parameters. The desired model method was chosen for adjusting all controllers. It is possible to compare the suitability of the simplification with regard to the requirements of the regulation.

Accuracy of non-contacting Temperature Measurement
Horák, Ladislav ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
This master’s thesis is specialized on the influence of correct parameters of emissivity, which depends on the temperature, wavelength and ambient environment. The investigation the parameter was taken infrared non-contact thermometer MI3 from company Raytek. To improve the quality of measurement was designed and programmed measuring utility program. The program was developed in the LabView 8.5 programming environment. To obtain the true value of the measured temperature of the target was designed and constructed the touch thermometer with the resistance dependent sensor. The thermometer is connected to the communication box of infrared thermometer and contain the same program. Nowadays are the most advanced IR thermometer with fixed parameters emissivity, which is applicable just to the real body in the vicinity of the parameter emissivity 0,95. For those IR thermometers were designed correction function, which would have temperature measured at a fixed emissivity parameter 0,95 set close to the actual value of the object.

Uncertainties Analyze of Indirect Measurement
Fišr, Petr ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
This diploma thesis is engaged with problems of expressing measurement uncertainty especially for indirect measurements. This issue is shown here on a few simple examples. Part of this work is a calculation module for the determination of measurement uncertainties, applied to the role of the laboratory 'measurement of the flow orifice.
