Most of the municipalities in Czech republic have old or even disfunctional sewage systems for built up communal areas. General combined sewage systems built earlier are being today replaced by solutions separating rain waters and sewage waters. Municipality Vír has currently only few sewage branches that consequently flow into Svratka river. Aim of this Diploma Thesis is to propose 3 solutions for sewage produced in communal areas of Vír municipality and its consequent disposal in sewage treatment plant. Each of three solutions feature combined gravity-driven and pressure systems of sewage lines as well as water treatment in proposed MTB as well as household and container WTP. Each of three variant is economically weighed with proposed budget.

The scope of the thesis is to design a roof substructure bus station in the area of Vysoké Mýto. The structure is designed of steel S355. This is the platform on the roof of two islands. The thesis has been processed by solving two variants, each variant were considered the main structural elements and then comparison was made between the two variants. Of these, one variant was selected for further processing. The first variant has a plan shape of a triangle with maximum dimensions of 58.00 m x 26,75 m. The main load-bearing structure consists of steel columns and girders of rolled sections, or HEB of castellated beams. The girders is the roof structure from rolled I profiles. Covering the roof is designed from the glass with supporting substructure of aluminum profiles. Rigidity is ensured in two ways braces of steel bars. The second option (which was selected for further processing) is L - shaped ground plan with maximum dimensions of 55,25 m x 33.40 m. The main supporting structure is made of rolled steel frames, HEB profiles and rods of steel bars. Supporting roof structure is designed of steel rolled I profiles. Roofing is again solved using the glass structure of aluminum profiles. Rigidity is ensured in two ways braces of steel bars.

This diploma thesis focuses on biogas stations used in agriculture. The thesis is divided into two parts - the literary research and the practical part. The first part of the thesis introduces the overall description of the biogas, its production, definition, and use. Moreover, the input and output raw materials of a biogas station are described. Subsequently, the operation and the chronological procedure used during the biogas production and resulting electricity in biogas station are introduced. The practical part of the thesis focuses on the actual situation in Europe and the development of both, the biogas stations' construction and the production of electricity from biomass. This part also analyses preferred raw materials of selected countries of the EU. Electrical capacity (IEC) and a particular state subsidy policy are also mentioned in the thesis. The research also includes particular examples of a good attitude and use of biogas stations in practice. In detail, the thesis deals with how these topics are dealt with in selected countries. In the Czech Republic, Slovakia, Germany, and Poland. In conclusion, according to the ascertain data, the overall summary and prognosis for the future are introduced.

The thesis is focused on energetic utilisation of biomass. It was used a qualitative research and document analysis of articles. The first part deals with the theoretical framework, therefore definitions and possibilities of biomass utilisation. The second part contains methodology, follows research and its evaluation. The first aim of this thesis is to summarize the utilisation of biomass as renewable energy and to distinguish positive and negative impacts of the utilisation of this source and evaluate its economic efficiency. There are several possibilities of utilisation of biomass, but it is necessary to select the suitable process and its utilisation. Based on the large number of examples from life it can be stated that it is economically efficient. The second aim is to identify main misconceptions related to utilisation of biomass. The main misconception is comparing the utilisation of solar energy, which has not left positive attitude of people to renewable energy, with utilisation of biomass. There are few examples of comparing photovoltaic with utilisation of biomass on the same level. In regard of the basic principles of utilisation of biomass, those two sources cannot be compared at all, they are not similar. Another misconception is apprehension of appropriation of land used for growing energy...

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.

The thesis deals with the phenomenon called breaking news in a continuous broadcast of news stations. It consists of theoretical and practical part. The main aim of the theoretical part is to describe the specifics of television news and their transformation caused by the introduction of continuous broadcast. In this context, the technical means used in Czech TV that allow the audience to watch the news live will be described in detail. The main aim of the practical part is to describe the mentioned phenomenon in connection with a specific event - the shootings in Uhersky Brod in February 2015. The main attention of the quantitative research will be focused on the continuous broadcast of CT24 on 24th February 2015 in order to obtain relevant results, which will illustrate the proportion of the information related to the shooting in the CT24 broadcast. The amount of the concrete news reports will be analysed as well. All the gathered results will be then presented in the summary. Powered by TCPDF (www.tcpdf.org)

This Master's Thesis concerns the travel ticket sales at Prague Main Railway Station. Based on a detailed analysis of provided data, its aim is to put forward suggestions on how to optimize travel ticket sales. Through evaluating the volume of travel tickets sold within the given time period and the number of open cash-desks, along with a cost analysis of sales channels, this thesis reaches its final conclusions. Microsoft Excel was the main analysis tool for compiling graphs. A sound knowledge of the current legislation which is stated in the theoretical part is necessary to help draw the right conclusions. This Master's Thesis, then, chiefly proposes informed suggestions on current sale process optimization in the ČD Center of Prague Main Railway Station.

This paper analyses the purchase and operation of vehicles on compressed natural gas. It contains a definition of Compressed Natural Gas (CNG) and discusses the various phases of its use in transport. It indicates the differences of this alternative fuel compared to traditional fuel such as gasoline or diesel. Then it focuses on the main reasons to support the use of compressed natural gas transport and talks about the legislation which has a major role in the development of alternative fuels. Then it specifies the disadvantages which can be associated with its use in transport. The last section includes an analysis on the specific example of the RWE CZ Group, which compares the different costs for compressed natural gas vehicles and vehicles which run on conventional fuel. Specifically the cost per kilometer of vehicle, CO2 emission and purchase price are given for comparison.

The practical part mainly deals with optimizition of various parameters in the derivatization reaction to achieve optimal conditions. Finally, the analytical method was successfully validated and applied to the analysis of a real sample.

The diploma thesis is focused on Storm water management in urban areas. The first task for processing thesis was to arrange meeting with MČ Brno - Bohunice Ing. Antonín Crha, who has provided necessary information about the targeted location the and the reservoir for accumulation of rainwater collected. The practical part of the thesis is to capture the rainwater drainage in the existing rainwater sewerage system using the newly built pumping station and then pumping into the existing, unused reservoir. Accumulated water in the reservoir is planned to be used for the needs of the city, gardeners and other customers. The first part of the diploma thesis describes the management of refined water in the Czech Republic, Denmark and Germany. The first part also provides description of measures and technologies for the management of rainwater. Finally, there is description of the pumping station and borehole objects and the program for calculating the rainfall from the urbanized area. In the practical part of the diploma thesis the selected variants are described, rewarded and evaluated. The diploma thesis deals with two variants, that are guided along the same route, with the difference of the construction of the drilled well in the second variant. Both variants are handled by pumping. The option of the gravity inflow was rejected because of the large countersink of rainwater sewerage.
