We present a status report on RAVE, our distributed, collaborative grid enabled visualization environment. We briefly review our architecture and related work, examine our collaborative support and relate this to an experiment carried out between SuperComputing 2004 (Pittsburgh, PA, USA) and the Cardiff School of Computer Science. Load distribution in RAVE(More)
This paper presents a distributed, collaborative grid enabled visualization environment that supports automated resource discovery across heterogeneous machines. OurResource-Aware Visualization Environment (RAVE) runs as a background process using Grid/Web services, enabling us to share resources with other users rather than commandeering an entire machine.(More)
A proper mechanical characterization of soft biological tissues of the human body has a strong impact on several medical applications such as surgical planning, virtual reality simulators, trauma research, and for diagnostic purposes. Adequate experimental data are needed to describe quantitatively the mechanical behaviour of those organs. We present a(More)
We present a brief review of 42 collaborative visualization systems, grouped into four application areas: collaborative problem-solving environments, virtual reality environments, multi-player online games and multi-user enabling of single user applications. The systems are then compared by five attributes: number of simultaneous users, user access control,(More)
Electrical impedance may be measured using electrodes on the surface of the cervix and recording the potential that results when an electrical current is passed. Increased hydration of the cervix has been described throughout pregnancy and occurs most dramatically before labour. This study compared tissue impedance measurements of the pregnant and(More)
Structure-based drug design is a creative process that displays several features that make it closer to human reasoning than to machine automation. However, very often the user intervention is limited to the preparation of the input and analysis of the output of a computer simulation. In some cases, allowing human intervention directly in the process could(More)
OBJECTIVE To investigate the use of electrical impedance measurements of the pregnant cervix as an objective measure of cervical favorability (Bishop score > or = 5). METHODS A prospective study of 86 women, investigating electrical impedance measurements of the pregnant cervix at the time of induction of labor. Transfer electrical impedance measurements(More)
This paper considers the potential of Augmented Reality (AR) in schools focusing on learning about materials. We have developed tools that target different age groups of school children using the concept of AR. Our AR tools had made a good impression on a number of school teachers and we have received positive feedback during our preliminary AR tools trials(More)
Medical undergraduate education and postgraduate training must adapt and adjust to the pressures and problems associated with traditional methods of teaching anatomy and pathology. This paper presents a 3D anatomical model visualization within a grid-enabled environment. The resource-aware visualization environment (RAVE) is a distributed, collaborative(More)
