Canonical community ordination comprises a collection of methods that relate species assemblages to their environment, in both observational studies and designed experiments. Canonical ordination differs from ordination sensu stricto in that species and environment data are analyzed simultaneously. Part I reviews the theory in a non-mathematical way with emphasis on new insights for the interpr...

This paper proposes a number of useful improvements to the Key-Chain-Web access control mechanism which expands the usability of the mechanism in different scenarios. The improved services shall demonstrate the flexible and adaptive nature of the mechanism achieved through the use of relationships within co-ordination among resources in cloud and grid systems to provide access control. The prop...

Metal oxides play a very important role in many areas of chemistry, physical and materials science. Metal oxides are formed as a consequence of co-ordination tendency of metal ions so that oxide ions form co-ordination sphere around metal ions and give rise to close packed structure. The different physical, magnetic, optical and chemical properties of metal oxides are of great interest to chemi...

In this paper we describe the Cambridge Collaborative Agent System (C2AS). This is a prototype system designed to demonstrate the functionality and basic architecture of a framework for co-ordination between different components (or agents) of distributed ‘Web’ applications. Co-ordination in C2AS is achieved through the use of tuple spaces, as used in Linda. However, the access primitives used ...

Visuomanual co-ordination requires the merging of ocular and arm information in a common frame of reference. Here we consider behavioural evidence in humans for the use of a viewer-centred frame in the specification of end point positions of reaching. We then review anatomical and neurophysiological data in the non-human primate that indicate a prominent role of the parietal cortex in the proce...
