Short-circuit resistance of the disconnector KBE, 38 kV, 3150 A
Šťastná, Antonie ; Šimek, David (referee) ; Bušov, Bohuslav (advisor)
The bachelor's thesis is focused on the calculations of electrodynamic forces and short-term warming for the disconnector of the company IVEP a.s. within the framework of the issue of short-circuit resistance. The first part contains a theoretical summary of high voltage switching devices, their division and functions. The next part describes the problem of short-circuit currents, and the third part contains an introduction to IVEP devices. In the fourth part, essential information affecting the short-circuit resistance test of the KBE disconnector, 38 kV, 3150 A, is selected and described from the relevant standards related to the topic of the thesis. The main part of the thesis is devoted to calculations of electrodynamic forces affecting on the relevant disconnector and calculation of short-term heating in critical places of the current-carrying path. In the thesis, the achieved results are commented on and possible adjustments are suggested in case of inequality with the standards.

Measurement of the fiber optical transport links
Ambrož, Jan ; Škorpil, Vladislav (referee) ; Reichert, Pavel (advisor)
This thesis deals with the measurement of optical transport links. In particular, the measurement of attenuation, chromatic and polarization mode dispersion. Specic me- asurement systems using a WDM and passive optical networks. Within each chapter are listed the causes and eects restrictive factors and methods of measurement. In chapter Attenuation measurements are described radiation and material loss as the main causes of depression. Methods whitch are described two lengths, insert loss and reectometri. Chromatic dispersion at dierent speeds of various wavelengths limits systems with high transfer rate. Methods of measuring the phase shift, dierential phase shift, pulse time delay and interference. Polarization mode dispersion is a random phenomenon caused double refraction, must be measured after completion of the route. Scanning wavelen- gth, traditional and general interference, reectometri and the polarimetric are methods of measurement. It described the measurement of WDM systems in three stages of its build. In brief PON networks are presented, with the specicities of the measurement over splitter. Most chapters are supplemented by the results and conclusions of practical measurements. At the end of the work are given by the two standards deal with the measurement of optical transport links.

Solution of Internal Threats in the Information Security Management System
Trčka, Martin ; Sopuch, Zbyněk (referee) ; Sedlák, Petr (advisor)
This diploma thesis deals with internal threats in the organization and their restriction with the assistance of DLP system. The first part of the thesis discusses the information security management system and describes requirements for the introduction of the ISO/IEC 27000 standards series. Next chapters detail internal threats and technical description of the DLP system. The second part of the thesis analyzes the organization and describes the process of implementation of DLP solution, which aims to reduce internal threats. The conclusion of the thesis describes acceptance agreement and financial evaluation of the implementation.

Analysis of the safety requirements of machinery in the European Union and the Eurasian Economic Union
Belov, Vjačeslav ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
The diploma thesis analyzes the European, Czech and Russian standards and requirements for ensuring safety of machinery and methodical process to ensure safety through certification of machinery and centrifugal pumps specially introduced onto the market in the Eurasian Economic Union and the Russian Federation. The first part describes the legislative documents, their properties and the current legislative requirements of EU and EAES. In the second part is an analysis and described comparison of legislative safety requirements of the European Union, the Czech Republic, the Eurasian Economic Union and the Russian Federation. In the third part is described comparison of standards, and were made updates. In the practical part is an analysis of risks pump manufacturer "SIGMA GROUP" according to the requirements EAES and proposed methods for reducing risk prevention. Also in the practical part is analyzed and is created methodical preparation of certification of machinery and pumps placed on the market in the Eurasian Economic Union and the Russian Federation.

I don’t care – Work is work!
Ferenc, Jiří ; Artamonov, Vasil (referee) ; Mikyta, Svätopluk (advisor)
Themes of my work are mass production and its error rate. The main target of my criticism is however the standard of goods, which separates aproved and disaproved ware. Beside criticism of standard I am also try to point out the power of uniformity of goods. In my opinion the uniformity of mass production can develop xenofobia and racism.

Technical standards for quality.
Nováková, Veronika ; Koška, Petr (referee) ; Fiala, Alois (advisor)
This thesis deals with the question of whether the technical standards have an impact on quality. We understand quality as a degree of compliance of requirements of a set of inherent features. Inherent feature means its own internal character of the object, whose quality is dealt. Quality and standards passed a long development, both from a point of law, as well as history, which began as early as in the old Mesopotamia by reference in Chammurapi Code. Since then, the quality changed its definition for several times, but the meaning of quality remains the same. It is necessary to mention the initiator of the quality who contributed by their work to its development, such as Prof. RNDr. František Egermayer, DrSc., who was the most significant initiator of modern understanding of quality in our country, then it is Dr. Joseph M. Juran, renowned author and "father" of modern quality management, also we must not forget William Edwards Deming, an American statesman and professor who is the most known of his work in Japan, and not least, world-famous personality Agnes Waddell, and other prominent personalities in this field. Today, quality control and normalizing ensure the main government authorities, such as Ministry of Industry and Trade of CR, which also ensures the management of other government bodies (ÚNMZ, ČMI, ČIA, see Chapter 6). The very Ministry of Industry and Trade may encharge a corporate entity to creation assurance and issuing Czech technical standards, their amendments and repeal. This assignment is non-transferable. As long as this assignment is valid, no other corporate entity must be encharged for this activity. There is no legal claim for this assignment. The costs of the creation of the Czech technical standards are covered by a person who requires processing. The costs of the creation of standards, notably the Czech technical standards transposing European standards, prepared pursuant to the request of the ministries or other central government departments and the costs associated with membership in international and European standardization organizations are paid by the State. In creation and issuing the Czech technical standards, their changes and cancellation must be provided the conditions laid down in the decision to assignment, as set out in Chapter 3.
