There are an increasing number of applications that require the construction of computerised human body models. The work presented here is a follow-up on a previously presented surface reconstruction algorithm, that has been greatly improved by following a local approach. The advantages of the method are presented, along with explanation of why its results(More)
In this paper, a short overview of project 3 "Advanced Flux Modelling" in the NOWESP project of the MAST II programme is given. The computational requirements of large scale 3-D ow and transport models of the NorthWest European Shelf are considered. The possibilities and implications of massively parallel processors for the simulation of these models are(More)
The avoidance of transfer-bound processing in large parallel computers is first analyzed with respect to the processor interconnectability. A quantitative measure is introduced for the processor substask interactivity, based on the number on nonzeroes in the interaction matrix. A similar quantitative measure can be introduced for the processor(More)
This paper discusses 'the shape of space', in terms of search algorithms and traversal operators. It is pointed out that it is the combination of traversal operators and representation that gives rise to a fitness landscape. This provides an intuitive background to recent discussions on the formal limitations on search algorithms. Dynamic and random(More)
