Single-Phase Induction Motor Calculation
Volf, Lukáš ; Ondrůšek, Čestmír (referee) ; Hájek, Vítězslav (advisor)
This work is in the first chapter deals with the basic properties of single phase and three-phase induction motors. The following describes the procedure for obtaining a starting torque of single-phase asynchronous motor. In the second part of the calculation is carried out single-phase induction motor with a permanently connected capacitor and its control, calculation of output values, the program proposed solution to this calculation in Microsoft Excel 2007 and calculated parameters of the development of methods of calculation were compared with measured, the values supplied by ATAS Náchod.

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 and realisation of microwave directional coupler
Nejedlý, Miroslav ; Motl, Milan (referee) ; Dvořák, Radek (advisor)
The diploma thesis deals with microwave directional coupler. The paper presents some of the microwave directional coupler and an analysis of bifurcations. The paper also discussed the various techniques of bifurcations and the bandwidth to which they are making. Proposal is implemented in two selected directional couplers and determining their size. They also performed using the selected simulation program selected two bifurcations. Furthermore, these couplers are made on the perimeter of the analyzer is verified by their actions and are verified by the actual parameters of the coupler.

LAN design in the Dept. of Telecommunications
Kučera, Filip ; Minarčík, Martin (referee) ; Kapoun, Vladimír (advisor)
This diploma thesis deals with the proposal and the maintenance of Ethernet computer networks in the Department of Telecommunication property in Brno. There is a description of communication line types used in LAN computer networks in the first parts of the work. Their advantages and disadvantages are introduced too. Further there is an existing situation of the computer network on the third and the fourth floor of the Department of Telecommunication building documented. This documentation includes a design and a list of used components. The existing computer network has some minor inadequacies that were taken into consideration in the new proposal. There is a completely elaborate documentation of the new proposed network on the third and the fourth floor that contains a detailed placement and a single component configuration including their description. This documentation should significantly contribute to more effective network maintenance in the future. The computer network maintenance does not contain only servers, printers or workstations. It's also necessary to consider network parts that are not so perceptible for common users. That means single segments of computer networks with its active devices. A web based application for the effective computer network maintenance is proposed and described in this work too. The application allows administrator to keep a well-arrange view of the single network segments. All network related information is saved into a database that can help with a solution of later occurred problems.

Technological Design of Part "impeller"
Kotrsal, Miloš ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This work is analysing existing technologies of paddle wheel production in a concrete engineering company which is engaged in turbochargers production. It is a breakdown analysis of technology from semi-finished product production to technological process of parts production, processing machines and tools. Here is proposed a new process of production technology. In the conlusion there is shown technical-economical comparison of existing and new technology.

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.

Design of Tagnpps 97 m3 Wagon Braking System in SS Braking Mode
Trubač, Pavel ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
At first part of my work is described the brake for freight wagon, its princip and control. Next part is dedicated to describe to brake with block and brake with disc. Main object of my work is concrete propose of brake with blocks and reason, why is this brake use on most of wagons. Next I describe requests for brake accessories for freight wagons, mainly for operation in SS mode. At second part is proposal for brake for freight wagon type TAGNPPS for operating in SS mode. Scheme of mechanical and pneumatic part, CAD model of this brake system, voltage analyses by FEM method of choosing component – brake lever, created in SolidWorks 2011 mode. For compare of result by FEM method is used analytic count of this component.

Worm conveyor of ciment
Radoš, Pavel ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This work contains a proposal for construction and workings of a worm conveyor system that can transport 50 tons cement per an hour. The introduction describes my proposal and workings of this machinery. In the calculation, I have mentioned calculation of the main proportions and drive under the relevant norms and self-fortress control of the stressed parts of screw-conveyor. Drawing documentation is worked into the ACad program and contains the configurations of the proposed details sub-assembly storage, worm shaft and welding body formation.
