The Distributed Link Service, a distributed system of link services for the World Wide Web [Carr et al 95, Carr et al 96], has been used to impose configurable navigation structures upon suites of static document resources in the World-Wide Web. This paper describes the integration of the link service functionality into a Web proxy server, and examines the implications for the service’s user in...

IntRoductIon A biopsy is the removal of part, or all, of a lesion, to enable histopathological examination and definite diagnosis. The word, ‘biopsy’ has been derived from the Greek words, ‘Bios’ (life) and ‘Opsis’ (vision): vision of life. Biopsy is the gold standard diagnostic procedure for obtaining adequate representative tissue for histopathological evaluation, for arriving at a final diag...

Introduction Diffusion weighted (DW) imaging is highly sensitive for bulk motion, which frequently occurs in vivo, such as in the lower brain areas, where the parenchyma pulsates rhythmically due to cardiac activity. It is known that for partial-Fourier (PF) imaging, the emergence of pulsation artefacts in DW images depends critically on the image reconstruction method. Specifically, it has bee...

The systematic archaeological and geological survey and excavations at Gona between 1992–1994 led to the discovery of well-flaked stone artefacts which are currently the oldest known from anywhere in the world. More than 3000 surface and excavated artefacts were recovered at 15 localities documented east and west of the Kada Gona river. Based on radioisotopic dating (Ar/Ar) and magnetostratigra...

When software is being created by distributed teams of software engineers, it is necessary to manage the work-flow, processes, and artefacts which are involved in the engineering process. The GENESIS project aims to address some of the technical issues involved by providing a software system to support distributed development. One of the parts of the system will be known as OSCAR, a repository ...

To investigate the neural correlates of the structural and semantic stages of visual object recognition and to see whether any effects of category could be found at these stages, we compared the rCBF associated with two categorization tasks (subjects decided whether pictures represented artefacts or natural objects), and two object decision tasks (subjects decided whether pictures represented r...

A 70 year old man is described in whom the presence of a cryoglobulin caused a number of unusual laboratory features which were not recognized as being due to a cryoglobulin initially. Pseudoleucocytosis has been recognized in the past. However, the intracytoplasmic inclusion bodies have only rarely been described. The curious appearance of the ESR has not previously been described.

This thesis examines the role of intuition in the way that people operate unfamiliar devices, and the importance of this for designers. Intuition is a type of cognitive processing that is often non-conscious and utilises stored experiential knowledge. Intuitive interaction involves the use of knowledge gained from other products and/or experiences. Therefore, products that people use intuitivel...

Cognitive artefacts (CA’s) are acknowledged as important for individual cognition (Norman, 1991), but their function in group work has been largely neglected. Because information is represented symbolically in the CA, there are several possible problem representations. How a representation encodes this information may influence its cognitive processing this is as important at the group level an...

Human intelligence has evolved along with the use of more and more sophisticated tools, allowing Homo Faber (from Homo Habilis to Homo Sapiens Sapiens) to cope with environment changes, as well as to adapt the environment to his needs. Analogously, in this seminal paper we introduce the notion of Agens Faber, conveying the idea that agent intelligence should not be considered as separated by th...
