Energy Audit of Chosen Building
Sivera, David ; Mastný, Petr (referee) ; Toman, Petr (advisor)
The aim of this thesis is the theoretical clarification of the issue of energy audit, thermal losses and energy audit. Bachelors thesis on the subjekt of energy audit is composed of several parts. In the first part the reader is familiar with the issue of energy audit. The thesis is describe what energy audit used, what does an energy audit consists. There is writte on, who is an energy auditor and what terms and conditions must be met to be able to devise an energy audit. Finally, there are described energy efficient buildings and energy label the building. The second part thesis deals with thermal envelope of the building. Thehe is described the composition of the walls envelope of the building and then overall heat loss the building calculate. The third part the thesis is describe the type sof installed electrical devices in the building. There is describe a type of elektricity meter and the main circuit broker. The last part the thesis is final evaluation. There are summary all possible adjustments in the building. Finally there are describe efficient solutions, where the investor use to the future.

Methods of analysis of vibration signals
Sivera, David ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
The aim of the thesis is to focus on the different methods of analysis of vibration signals. Focusing on the physical fundamentals of vibrations and a description of their origin in an electrical machine. Describe the vibration sources from mechanical across the electromagnetic to the aerodynamic. Defining the current defects of electric machines and sensors suitable for the measurement of vibrations in an electric machines. Introduction to the methods of analysis of vibration signals in the time and frequency domain. Then using some of these methods for the analysis of vibration signals measured asynchronous motors with different manufacturer defined production defect. The conclusion is composed from the comparison between measured and analyzed results.
