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.

Correction and Compensation in Temperature Measurement
Zábranský, Jaroslav ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The temperature belongs to the one of the basic values for a commercial measuring processes. The exact measuring of the temperature is the essential for a multitude manufacturing procedures and their regulations. This study is mainly focused to determine what influences can take the negative effect to exact temperature measurement. Content: List of of possible mistakes and their compensation wit the special focus on a notorious and frequent dynamic errors. Characteristic of those dynamic properties are important to analyze all the possibilities to correct different measuring systems. In this study we also present the simple model to deal with some error corrections

Mean Radiant Temperature Measurement
Truksa, Lukáš ; Zuth, Daniel (referee) ; Janečka, Jan (advisor)
This work is focused on parametry environment. In particular, this work is focused on the mean radiant temperature, which is a parameter with good meaningful capabilities. In The work we introduce with some ways mean radiant temperature measured and what are currently the sensor for this measurement. An integral part of this work is also Introduce the human thermal comfort, which plays an important role in measurement mean radiant temperature. In another part of the thesis is done propose a simple sensor for measuring the mean radiant temperature. And with other devices that are designed to measure the mean radiant temperature is verifying its functionality.

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.

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.

Sample tasks for automation education
Sileská, Silvia ; Janečka, Jan (referee) ; Davidová, Olga (advisor)
This bachelor´s thesis deals with the design and demonstration of tasks addressing combinatorial and sequential logic circuits. To resolve the assignment must be familiar with the theory of logical management, with program LOGO!Soft Comfort and issue of programmable controllers. Overall, the proposed six tasks are solved by basic rules for use in a logical management. Finally, it was necessary to verify the proper functioning of the proposed tasks, which it realized by using LOGO!Soft Comfort and programmable logic computers. The proposed tasks will serve as a demonstration tool for teaching the subject of automation.

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.
