Routing policies and real paths in the Internet
Hlaváček, Tomáš ; Peterka, Jiří (advisor) ; Lukeš, Dan (referee)
Routing policies are now represented by RPSL and by its evolutionary extension called RPSLng. These languages can be used for describing unique routing policy of each autonomous system. Experience shows that even though there are translation tools from RPSL and RPSLng to configuration formats of commonly used routers, the actual network configuration is rarely generated from RPSL sources and routing policy is then perceived as marginal paperwork, which often does not reflect the real network settings. There will be most likely a need for RPSL format change in order to remedy the discrepancies. To support this I present long-term measurements of inaccuracies in routing policies compared to real paths in the Internet. I also present a list of the most frequent problems, and I offer suggestions, how to reform RPSL to improve situation in the long term. Powered by TCPDF (www.tcpdf.org)

Mathematical models of military conflicts
Skopal, Martin ; Potůček, Radovan (referee) ; Čermák, Jan (advisor)
This thesis discusses the mathematical models used in the theory of warfare. The aim is to build and describe the Richardson model of conict and selected Lanchester models of combat. The models are subsequently analysed with a focus on stability. A part of the thesis is also formed by application of real data onto the models and by the subsequent evaluation of their results.

Measurement of Backbone Routing Parameters
Celárek, Ondřej ; Kořenek, Jan (referee) ; Matoušek, Jiří (advisor)
This thesis deals with issue of routing between Autonomous Systems. For routing between autonomous systems is used Border Gateway Protocol (BGP). The routers in Autonomous Systems modify their routing tables based on BGP messages. Routing tables are used for forwarding information on Internet. Issue of this thesis is analysis of change routing tables for eventually optimizing of routing architecture. First part of thesis is focused on theory of routers, routing ang BGP. Second part of this thesis focuses on implementation and execution experiments with routing tables. In this part are also described reached results.

Elimination of Discontinuity Supply of Electric Energy from Renewable Energy Sources
Radil, Lukáš ; Goňo, Radomír (referee) ; Braciník, Peter (referee) ; Mastný, Petr (advisor)
Doctoral thesis deals with domain of electric energy storage. It seeks to define the methods of accumulation, which can be used in industrial applications and define the conditions for the use of storage systems in electric power systems with extended penetration of renewable energy sources. In the context of current developments in this field is analyzed detail one of the perspective storage systems - Vanadium Redox Battery (VRB). One of the outcomes of this work is economic and energy analysis of storage systems, which are conceived with a disproportion between production and consumption of energy. The work was supported by the Centre for Research and Utilization of Renewable Energy (CVVOZE) no. CZ.1.05/2.1.00/01.0014 and research project no. FEKT S-11-9.

Mathematical pendulum
Kučerová, Barbora ; Dub, Petr (referee) ; Franců, Jan (advisor)
This bachelor’s thesis deals with the mathematical modeling of the behaviour of mathematical pendulum. The aim of this thesis is to find the equation of mathematical pendulum, compute the trajectories of solution and interpret their meaning, clasify the singular solution, plot the phase portrait in MATLAB software for the basic model and for the generalized model of the damped and driven pendulum.
