Parameters of FTTx networks - Quality of services
Winkler, Aleš ; Reichert, Pavel (referee) ; Münster, Petr (advisor)
The main subject of this diploma thesis is to make a proposal to improve the optical access network for the transmission of Triple play services. I would here to the reader clarify method of proposal of optical network. There are described the kinds of optical access networks with parameters, for which we must look by their construction. There are described the modern methods of construction optical network too. In the theoretical part are discussed used architecture of networks too. I met here known standards, which I compared for big importance by their choice. A reason of construction of optical network are services known like Triple play. These services together with their problems and parameters are here discussed too. At the end of theoretical part I listed here measuring method for getting negative attribute distorting the led signal. In practical part the locality witch use the optical signal as the source of information is ordered. These network use unfit connections and has less possibilities than usual and this is the reason, why is the network not able to supply Triple play in requested quality. At first the analysis of ordered network was needed. Situation was complicated by the fact, that it has been prohibited entrance to me. The structure of network and network parts was known and documented by me. I made the proposals to improve this network in practical part. By the first proposal remained original kind of access network FTTB, but used new parts with higher performance. By the second proposal I made the network FTTH, by which it was possible to use the last haul optical cables with treatment and using new elements. It was needed to create solution by flat units. The resulting proposals are here evaluated, compared and cost evaluated. For rejection of access to optical network I did not make measuring, so I made simulation for variant FTTH for getting some parameters negative acting transmission.

- Brno New Train Station and its Public Spaces
Valach, Lukáš ; Hybská, Bohumila (referee) ; Sedláček, Michal (advisor)
The topic of the diploma thesis is the design of a new Brno main railway station in the position "The River" (Ac), which was selected from several variants of the reconstruction of the Brno railway junction (ŽUB). The aim of this work is to create an architectural and urban concept, the function of which will be an important contribution to the development of the city of Brno, improving the traffic situation and comfort of the general public or residents of the new adjacent district Trnitá. The solved area is located in the cadastral area of Komárov, Štýřice and Trnitá. The height dominant is represented here by the Europoint building (115 meters). It is located in the axis of the new boulevard, at the other end of which we can see the picturesque Petrov. The main entrance glass hall is adjacent to Europoint. Public facilities are located in the front station area. North of Europoint, it is a smaller building with the function of start-up workshops and offices. Towards the river there are the pre-station square and the public transport terminal. The last building is a hotel with leisure activities. The end of the pre-station area by the river is designed with a park arrangement. It is important to connect to the bike path leading along the river. The river is widened at this point and a smaller accessible island is inserted into it. The new railway body is determined by the binding base of SŽDC, which contains the track on the embankment and on the bridge structure at the level of 7,1 meters above the level of the surrounding terrain. The solved part is bounded by two embankments, which will probably be created as massive reinforced concrete walls. The bridge structure lying between these embankments has dimensions of approximately 154x368 meters, which corresponds to the area of 8 football fields. The bridge deck will be drawn on columns of the given raster. The basic principle in the design of the new main station is simplicity, readability and functionality.
