Reducing the Measurement Frequency of Chloride and Ammonium Concentrations in Wieringermeer Landfill Leachate via SARIMAX Model

Research on sustainable landfill management has been studied since 30 years ago in the Netherlands, the principle of which is to reduce the emission of harmful substances from the landfill to the surrounding soil and groundwater. As for this purpose, the active treatment is applied on Wieringermeer landfill, meanwhile, the long-term monitoring...

Parametric design of steel orthotropic bridge decks for fatigue calculations

Currently the transport & planning (transport & logistics) group from Royal HaskoningDHV makes their pre-design for steel orthotropic bridge decks by using rules of thumb and experience. In the final design-stage this is verified whereby the force distribution is checked with the help of 3D finite element software (FEM). In this stage...

Towards a prediction of the intensity of a harmattan season

The harmattan is a seasonal phenomena in West Africa. It is a dry and warm wind which is able to transport large dust plumes. This study aims to get insight in possible triggers that may have influence on the harmattan season itself.To find a seasonal predictor which can predict the intensity of the next harmattan season, historical data is...
