Implementation of mechanisms providing Segment Routing for IPv6 (SRv6) using the FD.io VPP platform
Mjasojedov, Igor ; Dvořák, Jan (referee) ; Koláčková, Aneta (advisor)
The development of the mobile networks of fifth-generation (5G) accomplishes the requirements of transported services. New applications and services put high pressure on bandwidth, reliability and flexibility of the data transport. Due to this trend, network technologies need to be developed to address it and ensure transmission quality. This master's thesis aims at the Segment Routing (SR) concept and its commitment to improving transport quality in the transport part of 5G mobile networks. SR allows the integration of network programming into the traditional design of transport networks. SR uses either MPLS (SR-MPLS) or IPv6 (SRv6) on the forwarding plane. This thesis aims at SRv6. The main goal of the thesis is to design and implement a communication scenario for the transport part of the network with the SRv6 protocol. Docker platform is used to create a topology with all its nodes. The VPP platform is used to enable SRv6 on top of this topology. VPP has the ability to be configured via NETCONF protocol thanks to the Honeycomb agent, which can process NETCONF messages and propagate them to the VPP configuration. This configuration is done by the program Ansible, which can send NETCONF configurations to all SR nodes with Honeycomb installed. Testing and verification of the topology with all SRv6 policies is handled by the TRex traffic generator.

Pressure loss of catalyst carriers
Linda, Matúš ; Kilkovský, Bohuslav (referee) ; Jecha, David (advisor)
The diploma thesis is divided into four main parts. The first part deals with the issue of waste management and its energy utilization in waste incineration. Processed harmful substances produced by incineration as well as emission limits. It deals with the types of catalytic carriers, their description, production and more detailed processing of ceramic foam VUKOPOR. The second part is devoted to technologies utilizing catalytic processes and a more detailed specification of the process. In the third part there is processed the calculation methods for pressure losses for individual types of carriers. Fourth, the most extensive part describes the INTEQII experimental device, its technology and construction, as well as the principle of the practical part, measuring of the pressure losses of carriers. It includes the evaluation of pressure losses in separate categories of carriers, such as the bed, HoneyComb and VUKOPOR ceramic foam. Subsequently, a comparison of the pressure losses of all carriers is made relative to the reference size of 1 m. The impact of bonding of VUKOPOR foam samples on the size of pressure losses is discussed. At the end of this section, the suitability of calculation methods for individual carriers is evaluated, depending on the experimental pressure loss data.

Sandwich structure application on the formula car
Žídek, Tomáš ; Cejpek, Jakub (referee) ; Löffelmann, František (advisor)
The master thesis describes application of a sandwich construction for Formula Student car. It will replace the current tubular space frame according to FSAE rules. The introduction is focused on the information of international Formula Student competition, including TU Brno Racing Team. Then there are important rules for the construction of frames and composite monocoques. For the selected production technology are found strength properties of face sheets made of carbon and hybrid fibres. Another part of thesis deals with the design of the sandwich panel using analytical calculation to determine the bending stiffness. On the basis of these proposals are made three-point bending and shear tests. Using of FEM simulation is detected torsional stiffness of the tubular space frame and the monocoque concept from the proposed sandwich panels. The conclusion is devoted to a summary of the important information and possible monocoque manufacturing process.

Formula Car Monocoque Design
Žídek, Tomáš ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
The diploma thesis describes the design of a carbon fiber monocoque Formula Student car according to current rules. The first part is focused on construction solutions of frames used in Formula Student cars. Following is a summary of the important rules for constructing composite monocoque. Subsequently are described composite materials and their properties. The main part of the thesis deals with the structural design of the CAD program and a computational model to simulate the load case in FEM program. The obtained results from the analysis of the monocoque are compared with the values allowed by the rules of Formula Student. In conclusion of this thesis is evaluated the proposed composite monocoque.
