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...

Canonical correspondence analysis and redundancy analysis are two methods of constrained ordination regularly used in the analysis of ecological data when ordinations based on several response variables (for example, species abundances) are related linearly to several explanatory variables (for example, environmental variables, spatial positions of samples). In this report I demonstrate the adv...

In this paper we describe the Cambridge Collaborative Agent System (CAS). 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 CAS is achieved through the use of tuple spaces, as used in Linda. However, the access primitives used in...

Ordination is the name given to a group of methods used analyse multiple variables without preceding hypotheses. Over last few decades, use these in Earth science general, and notably analyses sedimentary sources, has dramatically increased. However, with limited resources oriented towards scientists on topic, application ordination analysis at times suboptimal misuse by authors can occur. This...

1 ABSTRACT The relations between two distance matrices on the same nite set are analyzed, via metric scaling, by correlating principal axis. Some applications are given and illustrated with examples. 1.1 Introduction Dissimilarities, similarities and distances are fundamental concepts in mul-tidimensional scaling and related topics. Euclidean and Mahalanobis distance also play a basic role in t...
