Mathematic model of steam turbine
Kroliczek, Filip ; Dokoupil, Jakub (referee) ; Pivoňka, Petr (advisor)
The goal of this thesis was to create a mathematical model of a steam turbine based on the data acquired by measurement, and to verify its behaviour. The first part contains research, which is supposed to introduce basic principles of the steam turbine and description of important construction parts and the possibilities of control. The second part describes the experimental identification method of least squares, used for the calculation of an ARX model of the steam turbine. Finally, the last part focuses on the program environment used for creation of the mathematical model and explanation of measured data analysis process. Furthermore this segment describes the created simulation program as well as a visualisation of the dynamic processes in the steam turbine, including the design of control.

Adaptive Control of a DC Drive
Krkoška, Roman ; Huták, Petr (referee) ; Skalický, Jiří (advisor)
The master’s thesis deals with method of adaptive control of electrical drives. It aims at control of DC motor with using self tunning controller (STC) and gain-schedulink in simulative enviroment of MATLAB. The first part of the thesis deals with of basic methods adaptive control of electrical drives and with of basic identification methods, computation of controller parameters and control laws of controllers. The second part of the thesis is aimed at applying adaptive controllers to mathematical model of controlled system. Include monitoring parameters of identification The thesis contains originate programs include source files.

Measurements results assessment and emission limits
Čech, Martin ; Jedlička, Filip (referee) ; Dvořák, Radek (advisor)
Main content of this task is summary and explanation of main methods,which can be used to evaluation the results from measuring of pollutants in combustion gases. The way which should be most acceptable for our datas will be consequently used in a simply example. There will be mentioned the importace of chosing the entering datas and their dependence on outer conditions. Another chapter will be devoted to emission standarts of main pollutants in Czech republic and in chosen world countries too. There will be mentioned the historical developement of these standarts and hypothesis to the future about this question too.

Determinants of car prices
Oravcová, Lenka ; Dlouhá, Zuzana (advisor) ; Čížek, Ondřej (referee)
The aim of the thesis Determinants of car prices is to create econometric model for price predictions of new and used cars. The prediction is based on the data provided by website of Slovak retailer of new and used cars. The model should detect statistically significant variables and determine their impact on final price. In the first part of this study, there is theoretical description of automobile industry and factors influencing price of car. The second part is devoted on developing the predictive model, suitable transformation of explanatory variables, interpretation of results and the car price classification in form of decision tree.

Surveying measurement in the capital construction.
PÁLENÍKOVÁ, Lenka
The accuracy appraisal and its evaluation with what the results of geodetic work are being achieved will be shown in this graduation thesis. As well as the related legislation and economic point of view of the price setting in comparison to other geodetic companies. One of the major surveyed area is testing of the used instruments - confrontation of achieved values with the values stated by manufacturer, accuracy analysis of the used methods and allignment of independent measurements of equal magnitude.
