Measurement and Monitoring Performance Parameters of Next Generation Networks
Grenar, David ; Vlček, Čestmír (referee) ; Róka,, Rastislav (referee) ; Smékal, Zdeněk (advisor)
The thesis is concentrated on the topic of next generation access networks. In the thesis, first of all, is conducted the analysis of the current state of knowledge with special focus on current technical and legislative developments and trends in access networks. The thesis describes the current structure of access networks and analyzes the current state of the issue of access technology. Measurement and testing methods for its verification depending on the type of network or operation of IP services are also described. Subsequently, the dissertation presents mathematical methods, that can be used in order to assess the access network model. In addition, recommendations and methods for monitoring and modelling access network data are evaluated. In particular, the subject of interest in this thesis is the issue of traffic intensity. The thesis presents a proposal for the construction of a mathematical modelling for the traffic profile and its application.
The use of nitrous oxide to increase the performance parameters of an SI engine
Dobeš, Tomáš ; Bazala, Jiří (referee) ; Beran, Martin (advisor)
This scientific article focuses on the use of nitrous oxide as an additive to fuel for improving the performance parameters of a spark-ignition engine. The results of experiments show that adding nitrous oxide to the fuel-air mixture can improve combustion and thus the performance of the engine. The benefits include increased power, reduced nitrogen oxide emissions, and improved combustion efficiency. However, it is also necessary to consider possible negative effects, such as increased nitrogen oxide formation at high temperatures. Overall, the use of nitrous oxide as an additive to fuel can bring significant improvements in the performance of a spark-ignition engine if used with caution and in accordance with relevant standards and guidelines
