Identification and use of guidelines for the design of computer supported collaborative writing tools

As groupware and workflow technologies become widely accepted, it is important to identify and clarify best practice at all stages of the development of those systems. One approach to the promulgation of best practice is to develop clear and effective guidelines for application in system development.This paper is primarily concerned with the identification of guidelines to drive the design and implementation of one class of groupware — collaborative writing systems. In particular, consideration is given to guidelines for systems which support groups of distributed collaborating authors working asynchronously.Three relevant areas are investigated. First, social and integration issues of generic groupware are presented. Second, the design of existing collaborative writing tools is addressed. Third, models of both individual writers and collaborative writing tasks are discussed. Guidelines are drawn from each area.The guidelines have been adopted in the design of MILO, a collaborative writing system. MILO is briefly described and the way in which the guidelines have been implemented in MILO is reviewed. In conclusion, insights gained from informal observations of MILO in use for both single and multiple author tasks are presented.

An FE analysis of the stresses in pultruded GRP single-bolt tension joints and their implications for joint design

FE (Finite Element) analysis is used to determine stresses on critical planes and around the hole edge in a two-dimensional model of a single-bolt tension joint in pultruded GRP (Glass Reinforced Plastic) plate material. The analysis takes account of bolt-hole clearance and friction at the contact surfaces between the bolt shank and the hole. It is shown that even when the hole clearance is nominally zero (∼0.2 mm) critical stress distributions, normalized with respect to the far field stress, are not invariant but change as the tension increases. Friction between the bolt shank and the hole and the small hole clearance (∼0.2 mm) are the principal factors which cause the zone of contact (defined by the angle it subtends at the centre of the bolt) to increase with increasing tension, and produce significant changes in the stress distributions at critical locations. These observations cast doubt on the validity of the simplified method for joint design given in the EUROCOMP code [In: Clarke JL, editor. Structural design of polymer composites - EUROCOMP design code and handbook. London: E.&F.N. Spon; 1996], because the method relies on normalized critical stress distributions remaining unchanged as the tension applied to the joint increases.

Soft computing agents for e-Health in application to the research and control of unknown diseases

This paper presents an ontology-based holonic diagnostic system (OHDS) that combines the holonic paradigm with multi-agent system technology and ontology design, for the organization of unstructured biomedical research into structured disease information. We use ontologies as ‘brain’ for the holonic diagnostic system to enhance its ability to structure information in a meaningful way and share information fast. To integrate distributed heterogeneous knowledge available on the Web we use intelligent agents augmented by the mechanisms of the technology of fuzzy sets, which automatically structures the information in the adequate ontology template. Our vision of how this system implementation should be supported by a solid security shield that ensures the privacy and safety of medical information concludes the paper.
