Decentralised recommenders have been proposed to deliver privacy-preserving, personalised and highly scalable on-line recommendations. Current implementations tend, however, to rely on a hard-wired similarity metric that cannot adapt. This constitutes a strong limitation in the face of evolving needs. In this paper, we propose a framework to develop dynamically adaptive decentralised recommenda...

1999{08{27 Abstract This paper introduces the dependable decentralised system architecture developed by the PHDS group. It describes the virtual redirector utilised by this architecture and how a decentralised network layer rewall application is implemented on it. Dependability of the design is achieved through the use of fault-tolerant protocols. The virtual redirector is implemented by a dyna...

Network control mechanisms in networks can be categorized by the time scales on which an individual control takes effect and they form a layered structure with respect to the time scales. In high-speed networks, the processing speed of each node is high but the propagation delay is the same as in slower networks, because it is constrained by the speed of light. So, the framework of network cont...

Central to the ethos of digital ecosystems (DEs) is that DEs should be distributed and have no central points of failure or control. This essentially mandates a decentralised system, which poses significant challenges for identity. Identity in decentralised environments must be treated very differently to identity in traditional environments, where centralised naming, authentication and authori...

Abstract: This paper develops a novel framework for power system stability analysis, that allows for the decentralised design of inverter based controllers. The method requires that each individual inverter satisfies a standard H1 design requirement. Critically each requirement depends only on the dynamics of the components and inverters at each individual bus, and the aggregate susceptance of ...

In this paper, different traffic light control structures over communication links, including the decentralised, quasi-decentralised, distributed and hierarchical networked structures, are considered. These structures used for coordinating multiple intersections, which could be a great application of networked control problem control for the signalised traffic light intersections that will help...
