They help create deeper and easier understanding of complex infrastructure protection problems. The first examples describes a minimization method to derive resistance curves directly from dynamic experiments, the second uses vulnerability modelling of hundreds of scenarios for safer urban environments and the third highlight hydrocode predictions, where testing would be impractical to impossible, especially to private businesses.en620presentation
