Measurement uncertainties in calibration of vibration sensors
Pražák, Jiří ; Uher, Miroslav (referee) ; Šedivá, Soňa (advisor)
This thesis deals with the research of uncertainties of the vibration sensor calibration measurement. The analysis of individual calibration methods of vibration sensors is also carried out in this thesis. Next, measurement of uncertainties for secondary calibration of the vibration sensors are analysed. The experimental part of this work is focused on determining the influence of different elements to type A uncertainty of vibration sensors uncertainty calculation. Experimental measurement was performed in an accredited laboratory for measurement and calibration of vibration sensors at FEEC BUT. Calculation of uncertainties of secondary calibration is also carried out in this thesis.

Automated measuring device for testing ELNEC programmers
Pražák, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
This thesis deals with the verification of parameters of Elnec BeeHive304 programmers. First, the reader is briefly introduced to the Elnec BeeHive304 programmer. Much emphasis is placed on the previous manual parameter verification. The aim of the work is to design and implement possible solutions for automation of the measuring process. In the main part of the thesis, two prototypes of a suitable automatic electronic measuring instrument for automated parameter measurement of the Elnec BeeHive304 programmer are designed and implemented.

preparation and evaluation of economic efficiency of selected investment project
Valášková, Petra ; Hrdý, Milan (advisor) ; Pražák, Jiří (referee)
The main goal of this study is to show a preparation of an investment project aimed on heating in a concrete company and to evaluate an economic effectiveness of the individual possible variants of the project. The project is unique due to particular financing from European union's grants and due to a goal of the company to meet new emission norm. The study is divided to three parts. In the first part, a theoretical one, is described a preparation of the project and an administration process of providing the grand from European Union funds. The second chapter deals with identification of the concrete investment project and the conditions of its evaluation. Moreover, important information about investor and circumstances of the investment project realization are discussed in this chapter. Finally, the process of the concrete grant approval is analyzed. The third part evaluates economic effectiveness according to cost measures and to net present value of the individual project variants. Because of a different lifespan of project variants the cost annual equivalent and the annuity equivalent has to be used. The results of cost measures and net present value are different. This pointes to the difference between cost only view and complex cash flow view. The final overall evaluation takes into consideration the ecologic part of the project. The final resolution has to make a compromise between various measurements. The study evaluates a real project. Therefore, the data are also based on reality.
