Safety assessment of a multifunctional machining centre
Šponiarová, Petra ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The thesis deals with the safety of the multifunctional machining centre of TOS KUŘIM – OS, a.s. In order to assess the safety of the multifunctional machining centre and the safety of the workers involved in its manufacture and assembly, it was first necessary to familiarise ourselves with all the legislation, which includes EU harmonisation and OSH legislation. Harmonised legislation is followed by harmonised technical standards. Compliance with the basic safety requirements of the relevant harmonised standards is a prerequisite for meeting all the requirements of harmonisation legislation. One of the basic requirements before placing a product on the EU market is to carry out a risk analysis. This has been done by correcting and supplementing the risk analysis of the milling machining centre, on whose design the analysed machining centre is based, to meet the requirements of ČSN EN ISO 12100:2011. Particular attention was paid to the production and assembly stage, where several standard production and assembly procedures were selected. Flow charts were drawn up for these selected procedures and a risk analysis was carried out using the FMERA method, which was developed by modifying the FMECA method. For each risk, measures were proposed to ensure that it was reduced to an acceptable level.

Simulations of impact of security requirements on industrial system performance
Loskot, Michal ; Blažek, Petr (referee) ; Mlýnek, Petr (advisor)
Safety and security is always a hot topic in the world of information security, but only a few solve how much cryptographic algorithms affect the performance of systems. Newer longer-key algorithms may provide more security, but it takes longer to encrypt data, that is, they may contain extra bits, which increases transfer time and uses more memory to store additional information. This bachelor thesis is focused on the analysis of the impact of the security requirements of the ANSI/ISA-62443 standard on the performance of industrial systems. Communication is simulated in which cryptographic algorithms AES and SHA were used. These simulations are carried out in the open source simulation tool TTool, which enables embedded systems, hardware and software modeling, and simple simulations directly from UML and SysML diagrams.

Návrh konstrukčního řešení mobiliáře do lékárny
Poloch, Jan
This diploma thesis deals with the structural solution for the pharmacy´s counter furniture. All the terms and authority conditions are respected and the solution meets the requirements according to the valid norms including safety demands. The theoretical part concerns working problematics, furniture equipment, introduction to used materials and the influence of anthropometry and ergonomics. The proposal of the constructional solution is developed through the drawing of producing documentation including relevant bill of materials, financial evaluation of the material outlays and visualizations.
