Plant oils for industry
Beran, Vojtěch ; Ficza, Ildikó (referee) ; Frýza, Josef (advisor)
This bachelor thesis describes usability of plant oils as liquid greases. The beginning of thesis follow up tribology problems and process of lubrication. The main section describes plant oils from perspective of their chemical composition and its closely related properties. In this thesis, plant oils are compared with another common liquid oils together with the comparison of its properties on specific application. In the conclusion, the thesis deals with summary of plant oils issues and with prospects for the future.

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.

Determination of measurement deviations of 3D optical scanner
Dokoupil, Filip ; Ficza, Ildikó (referee) ; Paloušek, David (advisor)
The goal of this bachelor thesis is to determine measurement deviations of the optical system ATOS Triple Scan, when the chalk and titanium coating is applied, by statistical data analysis. In the theoretical part, a short introduction to 3D reconstruction of real objects, distribution of structured light systems according to the pattern structure and existing knowledge about the scanning system accuracy is given. The practical part is based on the experimental measurement the calibration elements with specific chalk and titanium coating. As the result, the measurement uncertainty and the coating thickness is determined.

Simulation of the energy recovery circuit function
Kubíček, Ondřej ; Ficza, Ildikó (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis describes the design and optimization of a mathematical model for simulating the hydrostatic energy recovery systems. The mathematical model together with the experimental stand should be used to simulate the operating conditions of vehicles using the hydrostatic energy transmission. These include vehicles for collection of municipal waste, public transport vehicles, or for heavy construction machinery. The paper summarizes the current efforts in the design of analytical models, describes the program developed in MATLAB, and is devoted to analyzing the influence of individual input parameters on the output calculation.
