Designing is a knowledge-intensive activity. For novice design engineers, an important means of acquiring knowledge is to consult experienced colleagues. We observed novice-expert consultations as part of three engineering projects in a large aerospace company. Seven meetings were analysed in detail regarding the design activity, the content, and the form of interaction. Although the meetings were initiated for the purpose of information seeking, this process amounted to only 8% of the time compared to knowledge creation between novices and experts (47% of meeting time), and contextual information sharing (45% of meeting time). Both experts and novices were found to contribute equally and interactively to the discussion and analysis of solutions. The analysis showed how the processes alternated in the meetings. We identified tentative patterns on how these consultation processes change over the course of the design process phases. The micro-level analysis of the design activities and form of interaction provided a deeper understanding of how the consultation processes are discursively produced by the experts and novices. Finally, implications for design engineering practitioners are derived and suggestions for further research are provided.

By using an information survivability control system, the survivability of critical networked information systems can be enhanced using a variety of fault-tolerance mechanisms. Essential to the effective implementation of such mechanisms is communication from the error detection component to the various application nodes in the network. In this paper, we introduce a technique called Selective Notification for the communication of commands and alerts in very large distributed systems. The technique combines intentional addressing, content addressing and sender qualification in a single decoupled event-delivery mechanism. We show that effective targeted command and alert dissemination is achievable, and that Selective Notification allows systems to apply a wide range of event connectivity policies. We present details of an implementation of Selective Notification and the results of performance assessment experiments. Based on our preliminary performance data, we conclude that Selective Notification can be used to support survivability architectures in Internet-sized systems.Keywords: Survivable distributed systems, survivability, fault tolerance, event notification, decoupled communications.

“…In addition, we introduce a new system structure for dynamic allocation of mobile agents using online task scheduling to address the limitations of the current approaches and to achieve greater flexibility. The proposed multi-agent system structure is enhanced by push-based technology [2]. The mobile agents are created and cloned dynamically, initialized with service units and pushed from remote sites to local sites that are more convenient for local clients to access, thus speeding up the system's response.…”
