Reducing transformer inrush
Zoufalý, Marek ; Bušov, Bohuslav (referee) ; Šimek, David (advisor)
In this thesis is described the function and design of the transformer designed on ferromagnetic core, composed of transformer sheets. It is explained a transient inrush current of the transformer. In this work is inserted voltage and current waveforms, designed printed circuit board, serving to reduce the inrush current.

Transitional motion analysis of the optically trapped particle in under-damped regime
Sűsserová, Martina ; Damková, Jana (referee) ; Harabiš, Vratislav (advisor)
The bachelor thesis deals with the analysis of the movement of optically trapped nanoparticles at low pressures and familiarizes with methods commonly used in these conditions. The practical part of this work was done in Matlab, where the undesirable signal interference was filtered out from the original data and their influence on the phase portraits of the acquired transients was analyzed. Furthermore, the damped oscillator parameters are obtained from the records of average trajectories and the distribution of position data during the transient compared with distribution of position data at stationary state by histograms.

Confirmation of the Performance of Thermal Shock Test Chambers
Konupka, Richard ; Šedivá, Soňa (referee) ; Beneš, Petr (advisor)
The bachelor’s thesis deals with problematics of confirmation of temperature shock chamber and methodology for its successful implementation. Theoretical part deals with brief overview of environmental test chambers used for testing temperature and humidity changes on tested samples. Bachelor’s thesis also deals with analysis of methodology for confirmation of temperature chambers according to the technical standard which will be partially used for methodology proposal of temperature shock chamber. Practical part of the thesis is gradually devoted to the measurement procedure proposal, where is discussed chosen temperature sensors and fixture of sensors in the chamber. Also proposed procedure of confirmation is shown, described measurements, calculation procedures, uncertainty estimations and at the end of the thesis are discussed results.
