Protection of data transmission against long error bursts
Malach, Roman ; Lambertová, Petra (referee) ; Němec, Karel (advisor)
This Master´s thesis discuses the protection of data transmission against long error bursts. The data is transmited throught the channel with defined error rate. Parameters of the channel are error-free interval 2000 bits and length of burst error 250 bits. One of the aims of this work is to make a set of possible methods for the realization of a system for data correction. The basic selection is made from most known codes. These codes are divided into several categories and then the best one is chosen for higher selection. Of course interleaving is used too. Only one code from each category can pass on to the higher level of the best code selection. At the end the codes are compared and the best three are simulated using the Matlab program to check correct function. From these three options, one is chosen as optimal regarding practical realization. Two options exist, hardware or software realization. The second one would seem more useful. The real codec is created in validator language C. Nowadays, considering language C and from a computer architecture point of view the 8 bits size of element unit is convenient. That´s why the code RS(255, 191), which works with 8 bits symbols, is optimal. In the next step the codec of this code is created containing the coder and decoder of the code above. The simulation of error channel is ensured by last program. Finally the results are presented using several examples.

Privacy and anonymization in repositories of grey literature
Koščík, Michal
Current trends in the case law of the Court of Justice of the European Union suggest that the person who systematically processes documents in a repository can be a qualified as a processor of personal data. The operator of the repository can therefore face requests for anonymisation, or removal of information contained in his metadata in order to protect ones personal data . This paper aims to describe real life scenarion that can occur and provide instructions on how to proceed in similar cases.

Oral History on the Internet. Legal, Ethic and Methodological Aspects
Schindler-Wisten, Petra
This paper deals with the problems of publishing oral history on the Internet. The development of digital technology brings new possibilities to present oral history projects to the widest audience. The contribution of oral history from Internet is debatable, and brings many new challenges in this field, noting the need to bring new ethical, legal and methodological issues.
