Notwithstanding the fact that interest and applicability of knowledge management systems has augmented drastically during the past decade, the educational sector has struggled to garner attention in this respect. Current systems exhibit a vast amount of limitations and few instances were able to report successful implementation amongst academics and administration. This paper addresses these challenges...
In today's global economy, exploiting competitive advantage, increasing market share, enhancing efficiency, reducing costs and eliminating bureaucracy are becoming common objectives on the agenda for business owners and organizations. Through the proper implementation and adaption of Information and Communications Technology (ICT) projects, organizations are recognising the ability to realise such...
The persistent growth in demand for broadband communication services has lead to the widespread deployment of high-frequency Ka-Band satellite communication systems. This phenomenon however, presents a scenario whereby aircraft in mid-flight are evermore subjected to a diversity of external high frequency signals. The latter can potentially generate Electromagnetic Interference (EMI) with the communications...
The substantial increase in customer demand for office-like communication services during flights is pushing aircraft manufactures to implement wireless solutions inside aircraft. Nevertheless, aircraft safety is a paramount criterion for operators, thus the potential risks posed by such communication systems on aircraft equipment must be carefully assessed and respective countermeasures taken. In...
This paper models the EMI generated inside the cabin of a small medium-haul aircraft from a Node B antenna providing UMTS service. This is achieved by means of a three-dimensional raytracing algorithm which, with difference from previous cabin implementations, considers the volumetric properties of the cabin furniture and their complex electromagnetic material properties, to enhance modeling accuracy...
The increase in processing power of mobile multimedia terminals, the improvements in camera technology and efficient video compression algorithms have made the implementation of mobile free-viewpoint video (FVV) technology possible. However, the use of this technology in wireless environments poses a number of challenges. Amongst these there are issues in bandwidth utilisation and the limited supply...
