Content of this thesis is a methodology for creating ISMS Security Manual. Implementation of the proposal is supported by theoretical knowledge in the introductory part of this work. Practical process design methodology is conditional on the structure of the international standard ISO/IEC 27001:2005.

This master's thesis is focused on the design of the implementation of information security management system (ISMS) into a specific business. In the theoretical part, it provides basic concepts and detailed description of ISMS. There is also described the analysis of a current information security state of the company. In the practical part, it provides a risk analysis and selection of measures to minimize found risks. In the final part is designed a process and a schedule of an implementation of the selected measures.

This Master’s thesis is focused on the implementation of information security management system in the enterprise according to the standard ISO/IEC 27 001. The first part contains theoretical background of the information security, the second part focuses on current state analysis and the third part deals with suggestions for improvement current information security.

The diploma thesis focuses on proposing an information security management system (ISMS) in a small company. This publication includes theoretical facts, which are needed to understand and design a ISMS. The design proposal of the ISMS itself is based on an analysis of the current status of the company's information security. The proposed security measures are based on the actual state of information security within the company, and on recommendations stemming from the ISO/IEC 27000 standard.

The master’s thesis is aimed at proposing an implementation of information security management system in a company. It covers basic theoretical background and concepts of information system security and describes standards of ČSN ISO/IEC 27000. Specific provisioning of ISMS is then proposed based on the theoretical background and analysis of current state.

The diploma thesis is focused on testing and design of a test system of merging unit which provides digital output according to IEC 61850-9-2. The parameters and distinguishing features of the test system are based on functional principles of merging unit and standards dealing with the testing of transducers. The proposed test system is based on modular PXI Express system from National Instruments. The desing is performed with respect to the possibility of generating test signals and measurements for voltage up to 38.4 kV and current up to 2000 A. The proposed test system meets the criteria for testing transducers of accuracy class up to 0.5. Assuming of calibration designed test system as a whole, this test setup has the potential to meet the technical requirements for testing transducers of accuracy class up to 0.1.

This master's thesis deals with the temperature-rise of selected parts of the low-voltage switchgear. The theoretical part describes the physical principles and the basic mechanisms of heat transfer. The next part describes the possible effect of elevated temperature on the device inside the switchgear. The master's thesis is awarded by ABB Ltd., so another part is dedicated to MNS switchgear. The following part describes the permitted limit of temperature-rise of switchgear in accordance with IEC 61439-1. In the practical part is a calculation temperature-rise of selected part of switchgear based on IEC 60890. Model in SOLIDWORKS Flow Simulation was created for the same part of the switchgear and thermal analysis was performed. The values of allowable temperature rise of individual parts are compared with the results obtained by calculations and simulations. In the last part is verified the possibility of calculating the temperature-rise in the EPLAN software.

La fiabilité des microcontrôleurs est cruciale compte tenu de leur utilisation massive dans de nombreux domaines, surtout dans des environnements sévères. De ce fait, la robustesse aux perturbations électromagnétiques, en particulier à propos des alimentations, est un axe de développement majeur, que ce soit pour acquérir un avantage comparatif sur le marché, ou simplement pour assurer la sécurité des biens et des personnes. En ce sens, nous avons étudié le test de ces circuits soumis à des agressions transitoires rapides en salve définies par la norme IEC 61000-4-4. Les mécanismes spécifiques de propagation de la perturbation en mode commun sont mis en évidence, ainsi que leur conversion en mode différentiel. Plusieurs méthodes de mesure, dont certaines originales, ont été développées pour valider cette conversion, ainsi que les modes de propagation. Sur cette base, le réseau de distribution des alimentations a été particulièrement étudié et son influence sur la robustesse du circuit a été mise en évidence. Enfin, cette thèse ouvre de nouvelles perspectives d’amélioration de la robustesse des microcontrôleurs, pour ce type d’agression, et donc de leur fiabilité. / The reliability of the microcontrollers is crucial considering their massive use in numerous domains, especially in severe environments. Therefore, the robustness in the electromagnetic disturbances, in particular for the power supply network, is a major development, whether it is to acquire a comparative advantage on the market, or simply to assure the goods and people safety. Therefore, we studied the Fast Transient Burst test of integrated circuits, as defined by the IEC 61000-4-4 standard. The specific propagation mechanisms of the disturbance in common mode are highlighted, as well as their conversion in differential mode. Several measurements methods, among which certain novel, were developed to validate this conversion, as well as the propagation modes. Based on this, the power distribution network was particularly studied and its influence on the robustness of the circuit was highlighted. Finally, this work opens new perspectives of improvement of the microcontrollers’ robustness, for this kind of aggression, and thus their reliability.

Eaton created a new safety controller architecture to allow our customers to design implement, verify and maintain a SIL-2 safety certified application for compliance with IEC 61508:2010 and ISO 13849 Functional Safety Standards. The new architecture has been implemented in a line of safety controllers SFX12 and SFX20 that extend the line of existing mobile controllers HFX12 to HFX48. The new controllers are targeted for controlling mobile and stationary machine applications with focus on steer by wire and propel by wire.
