Evaluation of present technologies in ensuring functional safety of machinery
Smetana, Štěpán ; Tůma, Zdeněk (referee) ; Zahálka, Jiří (advisor)
This bachelor’s thesis is concerning functional safety as a whole. The first part of the paper will provide a description of what we can imagine under the term of functional safety and why we should pay attention to it. The document also includes introduction of safety components used in a frame of functional safety and its brief description. You can find here methodical approach to calculation of performance level PL and safety integrity level SIL, this calculation is shown on an example of an emergency stop function.

Design of control production unit with product dimension verification
Janoušek, Roman ; Tůma, Zdeněk (referee) ; Houška, Pavel (advisor)
This thesis solves the issue of design of control system for production line with machine vision to obtain the position and size of products. Part of the line is a digital camera, a delta robot and pneumatic manipulators. The introduction outlines the objectives of the thesis, followed by a discussion of sorting lines, including an example of a sorting line in practice. The main part of the thesis lies in the analysis and solution of problems relating to the machine vision and its use on the production line as well as its integration into the control system. The result of this work is a control system for management of the line and functional positioning and dimensions checking of the product passing through the production line. The conclusion of the thesis reviews the outcomes of the thesis.

Analysis of the current situation in international banking regulation and its outlook for the future - from the Basel I Basel III
Růžička, Jan ; Taušer, Josef (advisor) ; Tůma, Zdeněk (referee)
The aim of the diploma thesis is to analyze the evolution of banking regulation from the turn of the 19th and 20th century with regard to the introduction of global standards of regulation and supervision. Great emphasis was placed on the status and functionality of the current regulation and also on its future shape as Basel III rules. In the theoretical part Basel I and Basel II projects are presented. The first of these is the concept from 1987 (Basel I) with the emphasis on greater stability and reliability of the international banking system. Basel I, however, represented a very simple and straightforward form of regulation, where the only monitored standard is bank's credit exposure. The amendment to Basel I and primarily Basel II, introduced a pillar regulation structure, which is still valid and provides national regulator a sufficient power to carry out its activities. The second, practical part of the thesis is devoted to current development and problems of banking regulation. This part introducing Basel III represents not only the key point of the gradual increase in the amount of regulatory capital until 2019, but also the introduction of uniform standards for measuring liquidity and strengthening the supervisory powers.
