Probability-based model for network traffic
Bednár, Peter ; Jelínek, Mojmír (referee) ; Molnár, Karol (advisor)
This work identifies several basic types of traffic in IP networks and describes main features. The basic network services such as HTTP, VoIP and electronic mail are discussed focusing mainly on HTTP and VoIP probability-based models for network traffic which are applied to the software simulation of real network.

The data transfer technologies in optical access networks (FTTx)
Matušík, Lukáš ; Míča, Ivan (referee) ; Reichert, Pavel (advisor)
The objective of diploma thesis is describe problems connected with designed of FTTX networks and bring the reader problems of data transmission in optical acces networks the type of PON. In the introduction are mentinoned individual technologies that already operate, and there are describe advantages disadvantages of the use topology point-to-point and point-to-multipoint. In the following chapters are dealt with problems with data broadcasting in the direction from final participant. In the other part of diploma thesis are described elements, that were used for the proposed transmission route. The own PON acces network was presented on the basis information obtained by comparing the various networks and the elements involved in them. The network presented in conclusion diploma thesis is involved in topology point to multipoint. This transmission route is simulated in the program that allows the involvement of network by the user’s need with real values. The acces network is simulated for different transmission speed and different distances. The assesment of created optical route results from the measured values, theirs source is program OptiSystem, these values are summarized in the final chapter.

Game theory in the current flood protection
Pokorná, Veronika ; Macháč, Jan (advisor) ; Louda, Jiří (referee)
In recent years a considerable attention has been devoted to flood protection measures because of great damages caused by floods. While planning measures the consideration is based on costs and benefits associated with their implementation, i.e. the application of cost-benefit analysis (CBA). In most cases the relation of upstream and downstream in river catchments is neglected, therefore in the practice a potential for a retention of upstream remains unused. This bachelor thesis deals with a projection of this upstream/downstream relation into the current flood protection. Mathematic method of the game theory is used for the analysis of the optimal allocation of flood protection measures between the upstream/downstream areas. The upstream/downstream relation is defined by the specific assumptions and conditions. On the basis of these specific assumptions and conditions a payoff 2x2 matrix is modelled. The thesis constructs individual scenarios of mutual positions of these two parts. Possible outcomes are analysed by using game theory, while taking into account liability for damages, negotiation options and transaction costs. Presented results of individual scenarios indicate that the game theory is a suitable tool for the assessment of an optimal allocation of flood protection measures and its application in practice is appropriate in conjunction with other tools.
