Fields of interest

  • (Temporal) network analysis
  • Nonlinear dynamics and epidemiological models
  • Monitoring networks with sentinel nodes and analysing a probability of infection of the network

Network analysis

Lupe

Trading events on different weekdays. This was handy to estimate the activity of the considered network over a timespan.

Network analysis II

Lupe

Median of trading events (blue dots) of single network nodes. The green line marks the confidence intervall.

Cluster analysis

Lupe

Nodes of similar invasion paths grouped into same cluster by the Jaccard-Index. Here 18 greatest network cluster with similar infected- (red lines) and recovered-curve (blue lines) over time.

Cluster entropy

Lupe

Since temporal invasion path change over time, once grouped clusters fade away over time as well. The figure shows a great entropy for a specific cluster which was grouped at the beginning of he observation.

Detection probability with Sentinel Nodes

Lupe

Sentinel nodes can be found by different methods. The figure displays 18 separate sentinel nodes with its network characterization and the relative infection time of each sentinel.
