Evaluation of cutting fluids aerosol contamination of working environment during metal turning
Svoboda, Svetozár ; Mukhametzianova, Leisan (referee) ; Kotek, Luboš (advisor)
The thesis deals with the contamination of the workspace with a liquid aerosol, which is generated by scattering and evaporation of the cooling fluid. Cooling fluid are primarily intended to lubricate, cool and clean the tool and the workpiece, but the unwanted side effect is the formation of a liquid aerosol that holds in the air of the workspace. In such a contaminated work environment, the operator is exposed to a certain dose of a liquid aerosol that causes dermatological and respiratory problems. The topic of the thesis was to find out the number of particles of liquid aerosol that arises under varying working conditions and its dispersion in space. This amount was determined by image analysis using a high-speed camera.

Identification and assessment of errors in the assembly line of the pneumatic valves
Kadilák, Tomáš ; Mukhametzianova, Leisan (referee) ; Kotek, Luboš (advisor)
This thesis is focused on identification and evaluation of errors during pneumatic valve assembly. Theoretical part describes tools used: quality gate, flow chart, Pareto diagram and FMEA analysis. Within practical part the current assembly process is analyzed with current errors and besides evaluation, the improvement priorities and ways to accomplish these improvements in an actual company are defined. If the company chooses to take the opportunity to implement these improvements, thesis also monitors the results and reaction to the change of the analyzed process to a certain point.

Ergonomic audit at university
Kazarian, Anna ; Mukhametzianova, Leisan (referee) ; Kotek, Luboš (advisor)
This thesis deals with ergonomic audit of the workspace and working conditions of a university. First, factors affecting students and researchers are analyzed, with focus on their effects on physical and mental health. Attention is mainly given to the effects of thermal and moisture parameter of air, carbon dioxide concentration, lighting and classroom and office equipment. Level of adaptation of the workspace to the needs of disabled students and faculty is also considered. In the practical part of the thesis, the proposed audit is carried out at the Faculty of Mechanical Engineering of the Brno University of Technology. Measurements of ergonomic parameters were performed in selected rooms. Based on their results, shortcomings were identified and corrective measures were proposed.

Risk analysis of crane operation
Attasek, Ondřej ; Mukhametzianova, Leisan (referee) ; Kotek, Luboš (advisor)
The topic of this master's thesis is focused on the area of safety in lifting technology. Specifically, to prevent mistakes during bridge crane operations and to increase reliability of the human factor. The thesis summarizes the most important legislative regulations for crane operators, including the requirements for operation. Furthermore, there are analysis of bridge crane accidents including data about number of occupational accidents. Other part of the thesis deals with analysis HTA, human HAZOP, BOMECH and FMEA. Conclusions are set based on these analyzes and preventive measures are suggested.
