In this thesis, we develop mathematical models for the optimal deployment of security forces addressing two main challenges: adaptive behavior of the adversary and uncertainty in the model. We address several security applications and model them as agent-intruder games. The agent represents the security …

The Noordwaard is a recently realised high water floodplain near Dordrecht. The design plan of the Noordwaard is an answer to the increasing river discharge extremes, combining water safety, agriculture, recreation and nature management. However, in terms of governance a gap has emerged. The Department …

210,000 tons of textile waste is produced in the Netherlands every year - that is equivalent to 350,000,000 pairs of jeans. There are opportunities to use this waste stream as a resource for new materials in a circular economy, however. One such new material is the biocomposite RECURF. This material …
