Optimisation of a Voice Transmission in Communication Networks
Novák, David ; Polívka, Michal (referee) ; Škorpil, Vladislav (advisor)
This master’s thesis deals abou the transmission of voice in communications networks. The theoretical part describes criteria for optimizing voice, such as quality of service, type of service, level of service, service type, and mean opinion score. Next I describe the Internet Protocol, comparing IPv4 and IPv6, VoIP, including security, protocols and parameters necessary for transmission. Other part is about neural networks. There are basically described the neural network, Hopfield neural network and Kohenen neural network. The research is based on a comparison of the network without ensuring the quality of service and with ensuring quality of service. Then, there are compared two types of switches. Classical switch-controlled sequentially, and switch controlled by neural networks. The overall simulation program is implemented in Opnet Modeler. The conclusion deals with the creation of laboratory tasks in this program to compare the different systems of ensuring quality of service.

Modern Approaches in Managerial Communication
Novotný, Lukáš ; Jelínek, Jiří (advisor) ; Voráček, Jan (referee)
The introductory part deals with the fundamental characteristics of communication, currently used communication models, analyze the communication process and describe social nature of communication using managers communication networks inside and outside the organization. After that, the work refers to specific forms of communication and their use with ICT technology. The practical part firstly examines the managers communication needs and then analyzes the claims and demands for communication strategy. The gained knowledge is then used to design specific management communications system.
