Abstract:

The energy trading system is an essential part of critical infrastructure systems. If adversaries were to exploit the vulnerabilities of energy trading systems that can disrupt electricity generation and supply nationally, resulting in a devastating chain reaction. This study designs an architecture to safeguard the trading system for Australia’s wholesale energy market. The outcome of this study is a roadmap of a viable and sustainable system architecture for the future development of energy trading systems. It includes a design of three achievable security control subsystems to record and pr

Abstract:

<p>Communication tools such as text-based instant messaging, voice and video relay services, real-time video chat and mobile SMS and MMS have successfully been used among Deaf people. Several years of field research with a local Deaf community revealed that disadvantaged South African Deaf&nbsp<br>people preferred to communicate with both Deaf and hearing peers in South African Sign Language as opposed to text. Synchronous video chat and video&nbsp<br>relay services provided such opportunities. Both types of services are commonly available in developed regions, but not in developing countries

Abstract:

Le support de qualité de service (QoS) dans les réseaux MANETs (Mobile Ad-Hoc NETworks) a attiré une grande attention ces dernières années. Bien que beaucoup de travaux de recherche ont été consacré pour offrir la QoS dans les réseaux filaires et cellulaires, les solutions de QoS pour le support du trafic temps réel dans les MANET reste l'un des domaines de recherche les plus difficiles et les moins explorés. En fait, les applications temps réel telles que la voix et la vidéo ne pourrait pas fonctionner correctement dans les MANET sans l'utilisation d'un protocole de contrôle d'accès au suppor

Abstract:

The purpose of this study is to examine how the Swedish public broadcaster SVT depicted domestic measures taken by the government and other authorities as a result of the covid-19 pandemic with attention to their double role as public service. Public service media have a unique role in both acting in favour of the authorities when providing crucial information to the citizens and acting in favour of the public when investigating the work made by the authorities. Building on framing theory and a theoretical framework consisting of public service concepts and governmental crisis communication, c

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
