Satellite-based telecom systems provide the best and quickest solution to reducing the digital divide in less-favored areas owing to their wide geographical coverage and the speed and ease of deployment of terminal equipment. However, satellite system must be efficient and cost effective, and capable of full inter-working with state-of-the-art terrestrial broadband networks. this paper presents a novel two-way broadband satellite architecture developed in the framework of the UNIC (UNIversal satellite home Connection) project, sponsored within the 6th EU Research Programme Framework. the UNIC system architecture provides TV-Centric triple play services to actual end-users in the home employing DVB-S2 and DVB-RCS technologies in the forward and the return link, respectively, together with a newly low-cost defined architecture for the distribution of connectivity to end-users, including an ad-hoc interactive Set-Top-Box.

Large distributed Real Time systems are time consuming to develop. they frequently overrun cost and time schedules. It has been claimed that Model Driven Architecture is able to address some of the issues that cause these problems. A high level of abstraction and automatic translation between models may help. Platform Independent models for the individual components of the system mixed with scheduling information may enable functional changes and real performance to be assessed early in the development. Establishing different views from the requirements repository may better fit the development engineers skill and reduce errors. this is a position paper that discusses current challenges for the model-based development of distributed real time systems and how they might be overcome. 1.

3D dynamic contrast enhanced magnetic resonance (MR) images may help to reduce the high re-excision rate associated with breast conserving surgery. However these images are acquired prone, whilst surgery is performed Supine which results in a large deformation that limits their usefulness. We describe here a registration technique based on a biomechanical model to account for soft tissue deformation between prone MR imaging and surgery. the accuracies of the individual registration steps are assessed off-line. We then report our first clinical experience with an image-guided surgery system which incorporates these algorithms. the system's accuracy is assessed against tracked ultrasound images, and is determined to be around 5mm for this case.
