System development is studied from the viewpoint of artefactsutilised during the design process. Different aspects of design artefacts arediscussed based on a pragmatic classification of design activities and aphilosophical notion of perception and representational artefacts.Statements about the relation between theory and design are made basedon materialist pragmatism.

This paper presents a location sensing system “Spreha” for sentient artefacts. Our approach towards context awareness is to use sensor augmented daily life objects for context sensing. Some of these artefacts are static in nature, like a cabinet, a bed, a refrigerator, etc. The basic idea in Spreha is to use these static artefacts as reference points for identifying the artefacts that are mobil...

Software artefacts at different levels of abstraction are closely inter-related. Developers require support for managing these inter-relationships as artefacts evolve during development. We describe a conceptual architecture and prototype for supporting traceability and inconsistency management between software requirements descriptions, UML-style use case models and black-box test plans. Key i...

Nephrite (jade) ornaments, especially ear-ornaments, are among the most attractive artefacts in Southeast Asian archaeology. As Loofs-Wissowa stated (1980-81: 57): “Ear-ornaments in general seem to have played, and are still playing in some societies, a greater role in Southeast Asia and parts of South Asia than almost anywhere else in the world.....” Because of the beautifully wrought shapes a...

Although security requirements engineering has recently attracted increasing attention, it has lacked a context in which to operate. A number of papers have described how security requirements may be violated, but apart from a few hints in the general literature, none have described satisfactorily what security requirements are. This paper proposes a framework of core security requirements arte...

In this paper, we present the notion of “sentient artefact” and its integration. Sentient artefacts mediate implicit and natural context extraction as well as low cost deployment of a smart environment. The most important advantage is that its state-of-use naturally extracts a user’s activity context because such an everyday artefact has inherent roles and functionalities. Moreover, a sentient ...

The multitude of applications offered by CMR make it an increasing popular modality to study the heart and the surrounding vessels. Nevertheless the anatomical complexity of the chest, together with cardiac and respiratory motion, and the fast flowing blood, present many challenges which can possibly translate into imaging artefacts. The literature is wide in terms of papers describing specific...
