Experimental Study of the Efect of Lubricants on Rolling Contact Life
 Šembera, Václav ; Ficza, Ildikó (referee) ; Nohál, Libor (advisor)
The aim of this bachelor’s thesis is to summarize the art of state in the area of the contact fatigue, lubricants and detection of the rolling contact fatigue exploiting the acoustic emission method. In the experimental part of this bachelor’s thesis are performed the rolling contact testing for the standard grease and the lubricant with EP additives by marginal exploiting the acoustic emission method. The effect of the lubricants on the rolling contact life is evaluated by basic rating life L10 stated by using Weibull distribution.

Acoustic emission signal processing for granulometry of solid particles
 Tkáčová, Denisa ; Fialka, Jiří (referee) ; Pikula, Stanislav (advisor)
This thesis deals with the processing and analysis of acoustic emission signals for solid particle granulometry. Acoustic emission is one of many methods for particle size measurment, which is an important part of production in many industries. Various parameters can be monitored and analysed for acoustic emission signals. This paper processes and analyzes a large dataset of measured acoustic emissions and then evaluates which parameters from the acoustic emission signal are appropriate to use for particle size determination.
