Testing of Distance Protection
Řehoř, Jiří ; Topolánek, David (referee) ; Orságová, Jaroslava (advisor)
The testing of distance protection in bachelor´s task is made a distinction between protection, requirements and relegation. This testing is also consisted in principle of function, describing terms of distance protection and comparing with time-current characteristics. The next step after short estimation was describing digital distance protection SIPROTEC 7SA511. The advantages are included in this estimation. The next part contains some configurations and connections with a test equipment in order to take control of measuring through the computer. The extended configurations are also comprised of two programms – DIGSY and TZO3. We had to make a suggestion of suitable methodics for measuring a time-current characteristic. We carried out three measurements where the test equipment was set to role of type TREND. A magnitude is generated at the output that is changed linearly in time with required rate (speed). We changed a current IX1 for our measurements that was undertaken with a rate of current rise. This process was given by a test equipment when the set values were constant. In the second measurement we modified a size of shift phase in the test equipment. In the third measurement we tried to set up different sizes of particular impedance characteristics (zone) inside of the distance protection where was set a neutral breaking time for the measured zone. On the contrary, the previous measurements had an absolute time.We have introduced evaluated results of measuring and observations in the end of this bachelor’s thesis.

Design of the expansion of 22kV distribution network in a specific area
Řehoř, Jiří ; Beneš, Jan (referee) ; Blažek, Vladimír (advisor)
The aim of this work is the reconstruction and development of the distribution network of DS to ensure electricity supply in the required quality to existing customers and new customers connecting to the planned industrial zone Šlapanice. The first part deals with the inclusion of a distribution network in power system, its distribution and composition. Subsequently, the work deals with the description of the management of distribution networks, cable and outdoor leadership and their parameters. It also contains guidelines for the design of high voltage networks. The end of the first part is devoted to calculating the steady operation of the network. In the second part, the proposed project using the PAS DAISY Off-line v 4.00 Bizon. Based on the available evidence is developed steady state operation. We found that lines are overloaded and need to be strengthened with regard to the development of industrial zones and adjusting the network to ensure safe and reliable operation. The conclusion focuses on the economic evaluation of proposed alternatives.

Computer and Internet in the School Learning Process (Focusing on the use of Characters of Creative Possibilities Progress)
Řehoř, Jiří ; Krykorková, Hana (advisor) ; Kasíková, Hana (referee)
in English Bachelor thesis examines the role of modern information technology, especially computers and the internet, in the process of school learning. It defines the basic concepts and tries to capture how the role of computers in the classroom changed during the last years . Bachelor thesis sets out to address the issue of computers and the Internet in education from two perspectives: a) focus and attention on the basic problems and potential risks in the use of computers and the Internet in the process of school learning. b) the possibility of usage of computers and the Internet with regard to the principles of Creative Possibilities Progress learning, and identification of effective methods and strategies and their involvement in the learning process. The introductory chapter briefly summarizes the history of computers from the early predecessors to the latest trends in information technology, presents some of the first famous global and domestic computers and the conclusion summarizes some basic concepts. The second chapter presents a computer in the school environment, shows examples of the intersection of computers and the Internet in various areas of education and outlines the different attitudes towards the usage of computers and the Internet. The third chapter deals with the Internet...

The use of multimedia teaching aids by students with special educational needs in secondary schools of the Jedlicka Institute
Řehoř, Jiří ; Komárková, Tereza (advisor) ; Krejčová, Kristýna (referee)
(in English): The diploma thesis deals with the role of multimedia teaching aids in the teaching of students with special educational needs in the specific environment of the secondary schools of the Jedlička's Institute. The aim of this diploma thesis is to find out, through pedagogical research, the use of multimedia learning aids and the attitudes of students and teachers to multimedia teaching aids in the process of teaching. The thesis is divided into the theoretical and practical part. In the theoretical part, which is primarily focused on teaching aids, the term "multimedia teaching aid", which is further worked at thesis, is defined. Practical part of the thesis is the pedagogical research at the secondary schools of Jedlička's Institute, starting points, results and evaluation.The research takes the form of a case study. The methods used are questionnire surveys, participated attendance at classes and interiews with students and teachers.

Total two-year evaluation (2009 - 2010)of pilot project examination of thyroid gland function in group of pregnant women
Řehoř, Jiří ; Springer, Drahomíra (advisor) ; Límanová, Zdeňka (referee)
In the years 2009 and 2010 the pilot project investigating the function of the thyroid gland took place in 13 cities of the Czech Republic. In the context of the screening of congenital developmental defects the levels of TSH, FT4 and anti-TPO in serum were by women in the first trimester of pregnancy investigated, after signing informed consent. For the determination of analytes there were different analyzers used, which laboratories possess and are able to carry out the necessary examinations. Most of analyzers the reference intervals for TSH, FT4 and anti-TPO has set up from the manufacturer. These reference intervals are suitable for the normal population, neither less for pregnant women. Data from this project was evaluated using the newly calculated reference intervals for pregnant women, which are for the group of investigated women much more appropriate. From the total file of 3,484 pregnant women, it was thanks to these new reference intervals captured about 100 pregnant women with increased levels of TSH more, than in the use of reference intervals of producers. The comparison of reference intervals from the manufacturer with the newly calculated reference intervals for pregnant women managed to surface FT4 to find out about 126 more women below the surface of the new reference interval, than...

Analysis of Information in Chosen Emergencies
Řehoř, Jiří ; Toman, Prokop (advisor) ; Pavlíček, Antonín (referee)
This thesis focuses on an analysis of information in emergencies. Initial background regards two terrorist actions, namely 11 September 2001 in the U.S. and 7 July 2005 in London. In addition to the well-known official versions, the thesis also describes the so-called unofficial versions of these events. Awareness of both versions may be used to assess the impact of various elements on the analysis of information in emergencies from the perspective of the "ordinary" public as well as various analysts, government and military officials. The thesis also introduces positions of individual entities on analysis of informa-tion directly in the course as well as following the above-mentioned incidents. Finally, after analyzing the available information, I suggest the solution of a different type of incident, which is set out in detail at the end.
