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.

Design of Car Initiator
Suchý, Jan ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The bachelor thesis is focused on proposal solution of automotive initiator construction and design. The proposal is being carried out with regard to the need to ensure the maximum functionality of the whole element. As for the choice of materials and used technology the costs and procedures commonly used today are not being taken into account. The main objective is to eliminate the shortcomings of current automotive initiators and the proposal of technological procedures in the production of a new component.

Roof structure of construction for social purposes
Bašista, Ján ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The work treats the static recalculation of an existing roof structure of a construction for social purposes and proposes two variants of the design of a new roof structure. The construction has a rectangular ground plan of 30 m x 47 m and the roof structure is placed on the load bearing circumference concrete walls. Except for the load constituted by the function of the construction and by the climatic area, an extra load of 2 tons suspended at any place of the structure is considered because of the special requirement of working and technological equipment. The variant no. 1 is designed from the steel S355. The variant no. 2 is designed as a combination of the wood GL24h and the aluminium EN-AW 5083. Both of the variants have 11 transverse load bearing girders. The purlins are perpendicular to the girders and are placed on them. Stiffness is secured by roof stiffeners.

Heat exchanger design
Tatýrek, Lukáš ; Kudela, Libor (referee) ; Baláš, Marek (advisor)
The designed heat exchanger is part of a cogeneration unit, which I am considering as a possi-ble alternative for acquiring electrical and heat energy during heating season. The objective is to compile research about usable heat exchangers, pick a suitable technology for flue gas water application, calculate and design a heat exchange surface, calculate pressure drops and pro-cess the enclosed drawing documentation of the heat exchanger. For calculations, the recuper-ation gasket plate heat exchanger was chosen. The design of gaskets is nonstandard as it has been made for higher than usual temperatures. The result of this work is a heat exchanger with uncommon dimensions with a very low count of plates.

Water Management Solution of Mlýnka reservoir
Řeháková, Adéla ; Janál,, Petr (referee) ; Starý, Miloš (advisor)
Diploma thesis deals with flood protection at small basin flow Mlýnka. Object of thesis is first design of flood protection – dry reservoir. Part of thesis is theoretical, which describes general design, constructional solution and basic information about operation and maintenance. Next part of thesis describes specific design of dry reservoir. In the end, there are evaluations and comparison with bachelor thesis. Programs, which were used for elaboration, are AutoCAD, ArcGIS, HYDROG, HEC, MS Office.

Passive optical networks WDM-PON
Havliš, Ondřej ; Šifta, Radim (referee) ; Münster, Petr (advisor)
The work deals with optical access networks, passive optical networks, especially WDM-PON. Features a modern solution to connect users to the optical access network using optical FTTx connections. Describes the different types of FTTx connections, their parameters and construction technology. Practical work is a practical application of theory for the development of various design and simulation of WDM-PON networks. Each proposal includes the construction of technical solutions optical access networks, the technology used and the balance of the reduced pricing WDM-PON network. The penultimate part of the work consists of design models simulated WDM-PON networks by the simulation program OptSim. The conclusion deals with the evaluation of individual design and simulation of WDM-PON networks.

Steel load-carrying structure of production hall with bridge crane
Štulrajterová, Terézia ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
This bachelor thesis deals with the design and assessment of a steel load-bearing structure of a two-aisle production hall. That hall has a rectangular ground plan of a width 32 m (20 + 12 m) and lenght 54,54 m (9 modules distanced 6 m from each other). The main aisle is 10 m high and inside is located a overhead crane with carrying capacity 5 t. The second aisle is used as a storage area for materials that have already been produced. The skeleton of production hall is made of a ten transversal bindings. Lattice trusses are hinged mounted on constraint pillars of solid poles. The hall is situated in the north of the Czech Republic in the city of Děčín.

Supermarket in Olomouc
Brodecká, Denisa ; Bukovská, Pavla (referee) ; Pilgr, Milan (advisor)
The assigment for bachelor thesis was design and check of load-bearing steel structure in Olomouc in Moravia. The ground dimension are 24 x 40 m, height is 10 metres. The building construction is designed as a single hall with double-pitch roof and a slope 9°. Main frame is based on plate frame with anxial range 5 m. Transverse bracing ensure the rigidity of the structure from the plane of the frame. Wall cladding is storage on column and roof cladding is on purlins. The materiál used is steel S235. Bachelor thesis includes the assesment of the main load bearing structure elements, design of the selected details and their drawing solutions.
