Design of passive optical network
Žák, Ondřej ; Münster, Petr (referee) ; Reichert, Pavel (advisor)
Diploma thesis is dealing with access networks, especially with the passive optical network. The theoretical part is a list of different types of passive optical access networks, including theirs basic description, which then goes on to feature connectivity options for optical units, customers, including topology of distribution network. Analysis of different types of networks and the possibility of physical and logical design is the basis for successful design and prepa-ration of future optical access networks. Practical part is devoting to data analysis of measurement existing metropolitan network to be used for construction of optical access network in Brno, Ţlutý kopec – Preslova location. Data evaluation showed possibility of connecting with already installed network hence is created proposal of optical access network mentioned before. Selected location is analysed in detail and illustrated on situational scheme of location and customers, whose will be passive split-ters to central office. Consequently is developed project of optical access network based on data analysed date from measurements. Project is study and description of planned solution of optical access network in order to bring Triple Play services to customers. Within the interpretation of the feasibility of the project and verification physical layer pa-rameters of network was made a simulation in OptiSystem. The possibility of successful op-eration of the optical access network with the attributes entered in its design is approved in accordance with the evaluation results. The proposed network is passive in character of GPON standard, and the text describes in detail physical layer, proposed transmission speed, wave and attenuation plan of optical net-work. The work implies a specific line of HDPE ducts and microducts in them, including drawing the maps and identification in-depth. The work contains a description of the elements that are installed on the route – the number, type and eventually its length. Diploma thesis is introducing the technology and construction sequence of access network leading to its opera-tional state.

Funding of the Investment Project by the City of Ceska Trebova
Kašpar, Jan ; Švercl, Karel (referee) ; Režňáková, Mária (advisor)
The bachelor thesis is aimed at suggestion of optimal funding way of concrete project that is going to be realized by the City of Ceska Trebova. The project is focused on houselots construction by Ceska Trebova. The theoretical part of the thesis contains municipality functioning and funding. The practical part is focused on the municipality budget analysis and contains funding financial plan of the concrete project as well.

FTTx networks
Hradílek, Pavel ; Reichert, Pavel (referee) ; Filka, Miloslav (advisor)
The aim of this thesis is to clarify the issue of optical access networks, and to acquaint the reader with problems of their design and implementation. The introductory chapter describes the technologies and topologies, which are the most experienced in dealing with optical access network. There are a comparison of their basic parameters and limiting factors. Another part of the work is dedicated to progressive methods of construction such as microtubes and solution using the hanging cables, which due to the efficiency of construction, rapidity, economic and facilitate implementation. In conclusion the theoretical part there is issues of measurement. It describes a Optical Loss Test Set, OTDR method and method of measuring dispersion. Increasing demands on the capacity of the transmission paths, and their quality are caused of monitoring optical access networks, which can evaluate the failure on a route, target problems and inform service. The practical part compares EPON and GPON. In program OptiSystem was created model which these technologies are evaluated in terms of performance parameters, noise, jitter and eye diagram quality. The common feature of technology is transmission TDM frames, where EPON uses Ethernet and GPON technologies ATM. The outcome of simulation don´t show which technology is better, but result shows the conditions of the proposal of these technologies. At the end of work there are created several models for solving the optical access network with pricing per user. The most developed technology is FTTB in urban areas, when transmission in last mile uses copper circuit. This solution causing a rapid return on investment. Other technologies such as point-to-point FTTH or PON are implemented as individual proposals. Each of these solutions has advantages and disadvantages, so each project is unique and the solution is dependent on the project site and the requirements of customers.

Ecological influences during the construction of a family house
Bortlová, Nicol ; Vaňková, Lucie (referee) ; Kocourková, Gabriela (advisor)
The diploma thesis focuses on the ecological influences in the construction of a family house. The subject is to compare the properties of alternative building materials, determine the cost of building a house and design the optimal way of financing housing for a fictional married couple. Explains basic concepts, namely ecological aspects in construction, project management of buildings, pricing in construction, housing finance. The following practical part compares building materials in terms of their properties and environmental impacts during production, determines the costs of acquisition and operation of a family house and then finds out whether it is possible to finance the construction of the house through a mortgage loan. At the end of the work evaluates what percentage will increase the cost of building a house in the case of the use of materials, the production of which produces less negative emissions. Finally, the optimal variant of housing financing is recommended.

Determined and Specification of Auxiliary Work in Construction Supplies and Work
Levstek (Bradáčová), Šárka ; Kosová, Jaroslava (referee) ; Šmahel, Milan (advisor)
The thesis deals with extra work and unrealized work that originate at construction projects and further on during realizing the construction, both at new constructions, and at reconstructions and other construction activities. It mainly focuses on their origination and optimizing their amount in individual construction phases, from preparing the project through entering into an agreement with the supplier, to carrying out the project itself. The theoretical part outlines used basic concepts according to valid laws and regulations, and introduces individual construction phases including defining extra work and unrealized work. The practical part shows a real-world example of the negative influence of such work on the investor-supplier relationships and the analysis of failures by individual participants. The result of the thesis is processing a suggestion for reducing the frequent failures caused by the extra work and unrealized work, and a consistent evidence for better argumentation and invoicing between the investor and the supplier. The main aim is to prevent conflicts between the parties that arise because of admitting the extra work and unrealized work.

CONSTRUCTIVE - TECHNOLOGICAL PROJECT OF BUILDING POLYFUNCTIONAL HOUSE IN OPUSTENA STREET, BRNO
Dražilová, Michaela ; Šlanhof, Jiří (referee) ; Mohapl, Martin (advisor)
Project of master thesis solves brand new residential polyfunctional house with bike shop. The main object is a four-storyed, designed as a monolithic skeleton construction. The building is located in Opuštěná Street, Brno. The project is developed on the basis of project documentation and technical data, delivered by the designer in the behalf of investor requirements. Main goal of this project seeks to approach to real solution of the construction site. It is very important to compare also financial aspects, not only the technological. Last but not least, time requirements of construction plan and factual requirements of the customer. Constructive-technological project contains especially: technical report, site facilities, technologic regulation, schedule, financial budget, control and test plan, design of machinery, safety and health protection etc.

Possibilities of Financing House-building in Czech Republic
Harda, Marek ; Rompotl, Jaroslav (referee) ; Zeman, Václav (advisor)
Thesis "Possibilities of Financing House-building in Czech Republic" analyses developers' apartment building projects in Czech Republic. It is divided into three parts: the first part deals with academic definition of developer's project and related legal aspects, the second part consists of analysis of two already realized developers' projects and in the third part there are solution proposals in the current situation of apartment building with respect to possible grants from public or European funds.
