Environmental Impact Assessment for Chosen Plastic Molding Technology
Dufková, Hana ; Kotek, Luboš (referee) ; Krbalová, Maria (advisor)
This diploma thesis deals with assessment of environmental load by selected plastic molding technology. The first part is focused on the ecological legislation in the field of mechanical engineering, which also includes the production of plastics, and describes various methodologies for assessing the environmental load. Another chapter is an overview of polymers and their properties as well as the possibilities of plastics processing with description of individual types of production methods. The practical part of this work describes the composition of the produced piece and the injection molding process of plastic production. Its two methods (direct gating and hot sprue method) are analyzed and then the environmental load evaluation is performed using the LCA method – product life cycle assessment. The environmental load of both production methods is assessed.

Human reliability assessment
Kučera, David ; Kotek, Luboš (referee) ; Mukhametzianova, Leisan (advisor)
This master’s thesis aims to analyze the possibilities of failure of human reliability on the example of an induction heater from company Roboterm spol. s.r.o. in Chotěboř. The objective of a thesis is a review of a literature of human reliability assessment. Based on the analysis of the operation and a literature review and choose the appropriate method to perform the actual assessment of the reliability of human error. Final object of the work is to propose measures to increase human reliability.

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.

Reliability assessment of selected process in non-manufacturing company
Lukáš, Martin ; Kotek, Luboš (referee) ; Blecha, Petr (advisor)
The subject of the diploma thesis Assessment of the reliability of a selected process in a non-manufacturing company is the analysis of the reliability of processes and their risks. The partial goals were to perform a professional literature search of valid standards and a system analysis concerning the issue of assessing the reliability of the selected process. The first part of the diploma thesis deals with the approach to selected concepts and tools that are used in this work. Furthermore, the author dealt with selected requirements of the relevant standards ČSN EN ISO 9001:2016, ČSN EN ISO 14001:2016 a ČSN ISO 45001:2018, which relate to the issues addressed. The practical part introduces the company, especially the division of the company related to the process. Subsequently, the process was processed into an integrated flowchart and assessed using quality tools, namely FMEA analysis and Internal Audit. Based on the results obtained using these tools, the analysis revealed relevant risks and findings. In the last part, the author compared and summarized the results of the assessment and the identified findings, for which he proposed appropriate preventive measures to improve the selected process. Finally, the own conclusions and proposed preventive measures are discussed.

Design of Experiment
Lachnit, Zdeněk ; Bednář, Josef (referee) ; Kotek, Luboš (advisor)
The main subject of this master thesis is to evaluate using of Design of Experiment in industrial company in the development of LED modules for cars. In background study Design of Experiment methodology is described. Next part of background study describes the general principles of termography measurements, next chapter includes the information’s about LED technology and temperature degradation. At the beginning of the practical part is a description of the team analysis due to selection of factors, next chapter validates importance of vias. In next chapter methodology of print circuit board preparations and measuring are described. A next chapter describes the implementation of design of experiment at voltages 8 V, 13,5 V, 16,5 V. Designs of Experiments were made for four or five factors. The reason for this decision was the manual adjustment of printed circuit boards. At the end of each Design of Experiment is the recommendation of factors and interactions settings with regard on response, which is the minimal temperature. At the end of master’s thesis is the final evaluation.

Audit of ageing management in plants at major accident hazard
Juráňová, Bára ; Trávníček, Petr (referee) ; Kotek, Luboš (advisor)
This diploma thesis is focused on raising awareness of the phenomenon of ageing equipment. The aim was to analyse the current state of knowledge and to develop an ageing management audit method for the Czech Republic. The method was applied in a company located in the Zlín region. In the conclusion of the thesis, specific measures are formulated that the company should pay attention to.
