Tidal controls on river delta morphology

River delta degradation has been caused by extraction of natural resources, sediment retention by reservoirs, and sea-level rise. Despite global concerns about these issues, human activity in the world’s largest deltas intensifies. Harbour development, construction of flood defences, sand mining and land reclamation emerge as key contemporary...

Capability-based governance patterns over the product life-cycle: an agent-based model

In recent literature, there is disagreement over the temporal pattern of vertical governance of firms over the product life-cycle. We use a novel neo-Schumpeterian agent-based simulation model to investigate emerging patterns of vertical governance for different levels of imitability and substitutability of capabilities. We find that, in the...

Hydraulisch functioneren vispasseerbare cascades

Her en der worden in Nederland in beken en kleine rivieren vispasseerbare kunstwerken aangelegd om vismigratie mogelijk te maken en de ecologie van het systeem te verbeteren. Een veel voorkomende vispassage is de zogenaamde vispasseerbare stortsteen-bekkenpassage, ook wel cascade vistrap genoemd. Cascade vistrappen kunnen een opstuwende werking...

Application of a knowledge based design methodology to support fuselage panel design

Knowledge based method for solving complexity in design problems

The process of design aircraft systems is becoming more and more complex, due to an increasing amount of requirements. Moreover, the knowledge on how to solve these complex design problems becomes less readily available, because of a decrease in availability of intellectual resources and reduced knowledge transfer opportunities. Aerospace...
