In this chapter we describe the relationships between multi-agent systems, social networks and the Semantic Web within collaborative work; we also review how the integration of multi-agent systems and Semantic Web technologies and techniques can be used to enhance social networks at all scales. The chapter first provides a review of relevant work on the application of agent-based models and abs...

This paper presents a software framework able to extend the coverage of virtual communities across the boundaries of the everyday Internet by providing ubiquitous and integrated access to applications regardless of the users connecting though conventional, fixed-network computers, mobile, wireless-network devices or even interactive digital television set-top boxes. This software framework is a...

Modern software systems share with social organizations the attributes of being large-scale, distributed, and heterogeneous systems of systems. The organizational metaphor for software engineering has particularly been adopted in the field of multi-agent systems but not entirely exploited due to an inherent lack of collective levels of action. We propagate a shift from multi-agent to multi-orga...

We report, to the best of our knowledge, the first realization of a multi-wavelength distributed feedback (DFB) semiconductor laser array with an equivalent chirped grating profile based on equivalent chirp technology. All the lasers in the laser array have an identical grating period with an equivalent chirped grating structure, which are realized by nonuniform sampling of the gratings. Differ...
