Ramps and other devices for the entrance of handicapped to the buses
Pavlo, Matej ; Nohál, Libor (referee) ; Mazal, Pavel (advisor)
The bachelor work brings the critical assessment of the construction solutions of the aids for boarding of the physically handicapped persons in the busses of the municipal mass transportation and at the same time it deals with design of some tipping ramp variants, which try to improve the faults of the present ramps. The first part contains the review of the present situation of the aids for boarding and entrance of the physically handicapped persons. The second part contains the designs of the construction solutions, which could be of use in the busses of the municipal mass transportation. And in the last part are these designs reviewed and compared each other.

Identification of changes in surface texture of the selected materials by the method of acoustic emission
Eliáš, Jan ; Bumbálek, Bohumil (referee) ; Mazal, Pavel (advisor)
This Bachelor thesis deals with monitoring changes in surface roughness of moving metal objects rubbing each other on selected parameters of acoustic emissions. Parameters of the AE signal during the movement of bronze and cast iron bodies on the surface of a fixed steel rod were measured, recorded and analyzed. These results can serve for further research on assessment possibilites of the degree of wear of a surface using the AE method. Measuring was performed using a measuring product intended for AE and the Dakel sensors and measuring software.

Headstock for hanging of rotary filter
Kunorza, Michal ; Mazal, Pavel (referee) ; Brandejs, Jan (advisor)
The purpose of this bachelor thesis is to design headstock for hanging of rotary filter. First part deals about possibilities of hanging drum to supporting frame and choice of suitable transmiting element. Then it was provided experimental measuring of coefficient of sliding friction between flat belt, which is used to hanging of drum, and surface of stainless sheet in case of different rough surfaces and in case of different working conditions. Second part focuses on the design headstock for hanging of rotary filter and economical evaluation of fabrication.
