The Multiple-Choice Multi-Dimension Knapsack Problem (MMKP) is a variant of the 0-1 Knapsack Problem, an NP-Hard problem. Hence algorithms for finding the exact solution of MMKP are not suitable for application in real time decision-making applications, like quality adaptation and admission control of an interactive multimedia system. This paper presents(More)
The Multiple-Choice Multi-Dimension Knapsack Problem (MMKP) is a variant of the 0-1 knapsack problem, an NP-Hard problem. Due to its high computational complexity, algorithms for exact solution of the MMKPs are not suitable for most real-time decision-making applications, such as quality adaptation and admission control for interactive multimedia systems,(More)
We present our experience of building a prototype system based on the Utility Model for adaptive multimedia. The Utility Model is proposed to capture the issues and dynamics in multi-session multimedia systems where the quality of service (QoS) of individual sessions is adapted to dynamic changes of available resources and of user preferences. We present(More)
Real-time multimedia applications such as video and audio streaming, video conferencing and online collaboration are becoming increasingly popular. In order to guarantee effective support of many of these applications, the Internet must provide absolute Quality of Service (QoS) guarantees for such parameters as network bandwidth and end-to-end delay by(More)
The Strategic Information Systems Planning (SISP) process is critical for ensuring the effectiveness of the contribution of Information Technology (IT)/Information Systems (IS) to the organisation. A sophisticated SISP process can greatly increase the chances of positive planning outcomes. While effective IS capabilities are seen as crucial to an(More)
In today's technically advanced world autonomous systems are gaining rapid popularity. The goal of this project was to develop a system that could demonstrate this autonomy, as well as serve as a platform for future research work in the field of autonomous surface vehicles. The system presented is a powerful and relatively inexpensive Unmanned Surface(More)
The transmission of multimedia streams with a particular and guaranteed level of QoS (Quality of Service) from source to destination is a major challenge in multimedia communications over IP networks. In this paper, we introduce a generalized, flexible form of the traditional SLA (Service Level Agreement) between users and network owners, for the(More)
