Abstract
There is a growing interest in the area of self-healing systems. Self-healing does however impose considerable demands on system infrastructures - Especially in terms of openness and support for reconfigurability. This paper proposes that the self-awareness inherent in reflective technologies lends itself well to the construction of self-healing systems. In particular, the paper examines the support provided by the Open ORB reflective middleware technology for the construction of this increasingly important class of system.

Abstract
This paper presents the most innovative aspects of a middleware architecture that enables the provision of advanced personalized services in a Virtual Home Environment context. Multimedia considerations to extend the architecture to support mobile multimedia in a ubiquitous access terminal and network environment are also included.

Abstract
In VESPER1, the concept of VHE is being implemented and validated through the provision of a VHE system and various services to make use of it. This paper describes one of these services and presents how it validates VHE architecture aspects related with service adaptation to terminals and network, connection establishment, service personalization, session continuity/mobility and service advertisement. The paper also discusses some VHE usage scenarios of the resource discovery feature, showing how it plays an important role particularly in what concerns the ubiquitous service availability through the VHE platform.

Abstract
In this paper we describe how to integrate Internet protocols (TCP/IP) into a typical hierarchical master-slave fieldbus network, supporting a logical ring token passing mechanism between master stations. The integration of TCP/IP in the fieldbus protocol rises a number of issues that must be addressed properly. In this paper we particularly address the issues related to the conveyance of IP Datagrams in fieldbus frames (fragmentation/de-fragmentation) and on how to support the symmetry inherent to the TCP/IP protocols in fieldbus slaves, which lack communication initiative.
