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 [2]

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

Network analysis II

Lupe [3]

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

Cluster analysis

Lupe [4]

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 [5]

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 [6]

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.
