Detection of tie activation/deactivation.
Schematic view of the time intervals considered in our database and the different situations of tie activation/deactivation and the interplay between the tie communication patterns and tie activation/deactivation for a given observation time window Ω of length T = 7 months (shadowed area). Each line refers to a different tie while each vertical segment indicates a communication event between i ↔ j and δtij is the inter-event time in the i ↔ j time series.
