Formula Student Front Wheel Carrier Design
Černý, Filip ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
This thesis deals with the design of the front wheel hub and upright of Formula student car. First component is a short search on Formula Student event and comparing diverse structures of upright for use in both racing and road cars. It also includes design of hub and upright in the CAD program and computational model of the upright created in FEM program specifically for stress analysis in selected conditions. It also includes optimization of the overall proposal.

Formula Front Wheel Carrier Design Modification
Lněnička, Martin ; Svída, David (referee) ; Ramík, Pavel (advisor)
This thesis deals with the structural design of front wheel hub of Formula Student the car categories in the CAD system. It includes comparison to proposal design of the hubs, different concept of wheel-seat and wheel suspension of a formula cars and a motor-cars. There is described a few version of design front wheel carrier. The first step is proposed assembly wheel of Formula Student and the next step is realized analytic simulation a stress by FEM of the front wheel carrier and his construction modifications.

Principals, switching functions and routing techniques in computer networks
Dvořák, Pavel ; Pelka, Tomáš (referee) ; Polívka, Michal (advisor)
This bachelor thesis consider main principles and function of active network components. Mainly is intent to component working on the third level of referential model ISO/OSI, router. There are described its main parts and more closely charactered routing protocols. Then is verified the ability of dynamic routing to react to failure in the network and there is measured the reaction time of crossing to secondary route when using different routing protocols. Another part of the thesis is focused on the questions of Quality of Service (QoS) and its support in computer networks. There are explored various ways of the QoS configuration on the routers and the proper of them is chosen and applied to the test network.

Nemocnice – Bohunice public transport hub in Brno with settting – back track tramway terminus
Vaculíková, Barbora ; Veselý, Josef (referee) ; Pavlíček, Jan (advisor)
In my master thesis I deal with a design reconstruction of the current public transport terminus of Nemocnice - Bohunice. Terminus layout includes transfering the tramway line from Osová stop to the hub, the new tramway stop is a setting-back track. There is preserved the utilization of hub by existing city and regional lines of buses and troley buses and newly established regional bus lines (401,402,403,404) and also the entrance to the Bohunice hospital parking in the design. This design provides a safe flow of passengers and pedestrians and their safe road crossing.

Switch optimization in converged network
Švec, Adam ; Sobek, Jiří (referee) ; Škorpil, Vladislav (advisor)
Switch Optimization in a Converged Network thesis discusses the role of the Ethernet switch in the network. It describes differences between the switch and the hub in the network and the impacts on the collision domain size. In the converged network, priority data switching according to their origin and thus the qualitative point of view is also addressed - e-mails, voice services and multimedia will each behave differently. A real element, switch L3 - a switch with services quality support - is mentioned. The tool Matlab - Simulink is briefly described and a functional simplified model of the ethernet switch was created. Furthermore, the topic was used as a theme for a laboratory task in the subject Services of Telecommunication Networks. A model for Simulink and an example of the laboratory protocol for the created task are attached to the thesis.

VSAT Terminal Model
Kudlička, Miroslav ; Ondráš, Radek (referee) ; Baran, Ondřej (advisor)
This work deals with the description of the communication using the VSAT satellite network. A used network topology, frequency bands, satellite orbits and also an access technology are defined. The next part is focused on the VSAT terminal, where the block diagram is shown. A model of the indoor unit IDU is designed in the system background of Ansoft Designer. Individual parts of the system model are analyzed in terms of input variables. The results of the simulation are shown. The curves of BER before Viterbi decoding and after Viterbi decoding are shown too.

Program for design of CATV
Sedláček, Jan ; Hála, Ondřej (referee) ; Říčný, Václav (advisor)
The main task of this master’s thesis is to create an interactive computer programme for the design of small and medium television cable circuits. The first part of this document describes main conceptions of a modification and a distribution of television signals. There are also introduced basic topologies of small and medium sized distribution networks, some passive and active elements in the circuit including their usage. There is also described an algorithm for calculation of circuit’s values. The second part contains a detailed description of created programme with all of its functions. A part of this document is made by a sample calculation of the four variants of circuit and its comparison with computer calculation. In suplement are included selected parts of source code.

Trailer for EURO palette
Michal, Tomáš ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
Project detaily decsribe design of trailer construction which utilized gravitational roller way. Firstly we are going to focuse at determination of main proportion and later on at the construction of each single part ( frame, roller way and rear mechanism). All parts of the trailer have their own technological plan and project also includes 3D models of them. Obvious part of the project documentation is also functional counting where is determined named velocity euro-palett slide on roller way and fixity counting at once.

Drop forging of hub
Vostřel, Jan ; Novotný, Karel (referee) ; Štroner, Marek (advisor)
The project elaborated in a frame of Bachelor’s studies branch B 2307 presents a technology design of a forged piece – hub – a part of a gear box made by drop forging from 14 231.0 material. Drop forging in three operations was suggested on the basis of specialized studies on the subject of drop forging and calculations. Assumed series of 40 000 pieces a year, preciseness and automatization of production of the part, will be produced on the crank drawing inclinable press LMZ 2500 (producer Šmeral Brno, a.s.) with nominal tensile force 25 MN. Swages are made of alloyed instrumental steel 19 552.8, heat-worked according to drawing documentation. At the end of the project technical economic evaluation of the technology design is implemented.
