Generic characterization of diagnosis and prognosis for complex heterogeneous systems

Maintenance efficiency of complex industrial systems is an important economical and business issue. Main difficulties come from the choice of maintenance actions. A wrong choice can lead to maintenance costs that are not acceptable. In this paper, we propose a generic health monitoring system that integrates some diagnostic and prognostic capabilities to determine the current and future state o...

Complex fuzzy linear systems

Emergence of coherence in complex networks of heterogeneous dynamical systems.

We present a general theory for the onset of coherence in collections of heterogeneous maps interacting via a complex connection network. Our method allows the dynamics of the individual uncoupled systems to be either chaotic or periodic, and applies generally to networks for which the number of connections per node is large. We find that the critical coupling strength at which a transition to ...

Large Visualizations for System Monitoring of Complex, Heterogeneous Systems

As systems grow larger in size and complexity, it becomes increasingly difficult for administrators to maintain some shared sense of awareness of what's going on in the system. We implemented a large public display with appropriately designed visualizations that allow for rapid assessment and peripheral awareness of system health. By placing the visualizations on a large display in a shared, co...
