INCAS3 – Nonlinear Cochlear Mechanics

It is perhaps astonishing that in spite of the advances in medical imaging and other research techniques, the possibilities of visualizing damage to the human hearing system are very limited. Although there is a vast range of audiological tests that measure the effect of damage, pinpointing what is causing these effects is often impossible. This,View problem details

Witteveen+Bos – Monitoring the Sewer System

The old city centre of Delft is sensitive to both pluvial and fluvial flooding, especially specific areas in the eastern part of the city centre. This includes surcharging of sewers and flooding of streets and buildings due to storm events, overflowing of canals and high groundwater levels. In order to reduce flooding impacts, the canalsView problem details

CBS – Calculating Traffic based on Road Sensor Data

The Nationale Databank Wegverkeergegevens (NDW), a database for traffic data, contains the counts of more than 14,000 traffic loops, that are to be found in the Dutch system of motorways and provincial roads. During a day it is analysed how many vehicles of which type pass through these loops each minute. Each day this givesView problem details

MARIN – System Parameter Identification in Numerical Simulations

A common problem in numerical simulations is finding the correct parameter values of a mathematical model. A typical example from MARIN practice is the simulation of a ship manoeuvre, like a zig-zag or a turning circle (Figure 1), where the result is compared with the outcome of an experiment. The forces acting on the shipView problem details
