The thesis Establishment of the Linux internet gateway using advanced filtering focuses on~the installation of~the Linux operating system on~the older computers, that functions as a gateway to connect clients in the internal network to the Internet. The thesis describes creation an advanced filter with using iptables. Shows some types of security against attacks from the Internet. The other chapters are discussed, advanced traffic control mechanism (such as a TC and a qdisc). The system queue, it is highly beneficial where it is necessary to hierarchically divide traffic between users. It describes types of queue and assembled configurations for clients in the internal network. Next chapter describes the DNS server caching-only type and application denyhosts, which increases the overall security system. Have your own DNS server is certified, especially if we want to reduce the data traffic. Last chapter describes the RADIUS server and its implementation using Apache and MySQL database. Furthermore, the configuration options are described and the examples of the particular configurations are provided. Finally, it presented a system for authentication through the RADIUS server. The thesis seeks to provide a~complex view of security and filtering.

Využití přírodních hydroabsorbentů při mimokořenové výživě máku setého
Jelínek, Mojmír
The aim of this thesis was to evaluate the effect of a combination of foliar application of sulphur together with a natural form of superabsorbent polymers (SAP) in the spring poppy variety (Papaver somniferum L.) Onyx. The effect of sulphur application in the form of ammonium thiosulphate and elemental sulphur, both without SAP and in combination with SAP, on crop yield was investigated in a field experiment on a total area of 1.25 ha in the locality of Bedihošt' municipality. The evaluation of the effect was mainly based on hectare yield, then germination and thousand seed weight (HTS) were monitored, the health status of the crop was evaluated and an economic evaluation was made both in terms of total cost and with respect to the application of sulphur and SAP alone. The best results were obtained in the plot where ammonium thiosulphate alone was applied, followed by the combination of ammonium thiosulphate with SAP. The results show a very strong correlation between yield and germination (r = 0.96). In contrast, the effect of SAP was not sufficiently demonstrated in this work. The overall economic evaluation when all costs were included was positive only for the application of ammonium thiosulphate without SAP, all other options were loss making. In a direct comparison of the variants with the calculation of only the effect of sulphur and SAP, the application of ammonium thiosulphate without SAP and with SAP came out positive, while elemental sulphur with SAP and without SAP came out negative.

Czechoslovak Tourism in Socialist Yugoslavia. Institutions, Imaginations and Reality.
Jelínek, Martin ; Čechurová, Jana (advisor) ; Rychlík, Jan (referee)
International tourism has become a common part of human life. This phenomenon, originating in the modernization of society in the 19th century, has undergone a complex and long development. From its initial stages, when it was reserved for high society, through the understanding of its economic potential for the modern state and economy, to the final massification of international tourism in the second half of the 20th century. In a bipolar world, the specifics of the development of international tourism are shown with respect to which side of the Iron Curtain this tourism is developing on. A special example is if the development takes place somewhere on the border of both blocks. Czechoslovak tourism heading to Yugoslavia is a good example of blending the Eastern approach to traveling abroad with a specific model of the Yugoslav perspective on the phenomenon of tourism. Czech and Slovak tourists have been regular guests since the 19th century, heading precisely to the countries that made up the Yugoslav state. The presented work deals with how the institutionalization of Czechoslovak tourism in socialist Yugoslavia developed and was anchored, i.e. which institutions and in what way they ensured tourism, how and with which institutions on the Yugoslav side they were forced to cooperate and how this...

Optical fibres for ionising radiation measurements
Zbožínek, Tadeáš ; Jelínek, Michal (referee) ; Mikel, Břetislav (advisor)
The work focuses on studying methods of measuring ionizing radiation using optical fibres. More attention is paid to their use, together with scintillation materials. The proposed method allows the connection of an electronic detector with a scintillation sensor by optical means. The interconnection provides the possibility of shielding the detector from the effects of high ionizing radiation activities. The shielded detector will thus not be subject to the adverse effects of this radiation and can be used even for long-term measurements of high activities. First experimental measurements of reference sources verify the principle of the proposed method and help to select the best choice for the type of optical fibre.
