File copying is frequently used to implement ad hoc management of file replicas, backups and versions. Such tasks can be assisted by appropriate applications, at the expense of introducing some restrictions to the usage patterns. In particular, this is the case of interactions involving disconnected machines and transportable media. Panasync tries to support these actions by introducing a set of commands for file copying and re-integration that complement the file-system commands and provide support for dependency analysis among time-stamp assisted files.

Context awareness is a vital element in pervasive and ubiquitous systems. While most existing research has focused on designing context-aware systems to integrate into the environment, less attention has been placed on the interoperability among the entities comprising such systems. In this paper, we consider how the components of a context-aware system can collaborate to achieve a common goal. We provide a taxonomy of such Collaborative Context Awareness (CCA) based on three axis, i.e., goal, approaches and means. We also discuss a number of context-aware systems from different domains, i.e., augmented artefacts, robotics and sensor(/actuator) networks that exhibit some form of collaboration. Finally, we classify the different studied systems according to our taxonomy.
Pervasive computing aims to unobtrusively embed computersystems into everyday life environments to enrich the user experience without demanding the user's explicit attention. For pervasive computing to be minimal...

Motivation - In some situations EID's high-level visual design principles can be difficult to apply. A more concrete design methodology would make the framework more accessible for interface designers. Research approach - Graphics research was reviewed across a number of fields. The Visualisation Reference Model was identified as a useful model that could be used alongside EID's visual design principles. A case study is used to demonstrate this approach. Findings/Design - Supplementing a work domain analysis with a task analysis can reveal how information requirements are used. This allows data transformations and visual mapping to be carried out to generate visual components in an ecological interface design. Take away message - Task analysis not only improves the quality of our information requirements, it can also inform the visual design process.

With the introduction of Wireless Local Area Networking technology in recent years, many exciting applications are now closer to becoming a reality. One such application is the smart car or automated vehicle - a car capable of transporting its passenger(s) to their intended destination without human intervention. For this application, automated vehicles need to be able to co-ordinate with each other in a reliable and timely fashion. A logical approach to this problem would be to use existing real-time group communication techniques. However, existing techniques have been designed with a more static network in mind. In particular, group membership is more dynamic in the automated vehicle application. In this paper we outline new requirements for group communication suitable for such mobile applications. Such group communication must take into account the proximity of members of the group to each other. The Anois project, at Trinity College Dublin, is currently developing such a group communication system addressing these new requirements that arise due to mobility.
Software architectures have recently emerged as a level of design concerned with specifying the overall structure of a system. Traditionally, software architectures only provide static descriptions of the participants...
