Calibration of a model to predict the Peak Punch-Through Penetration Resistance of a Spudcan on Sand Overlying Clay

This paper demonstrates the use of a geotechnical drum centrifuge in the calibration of a model to predict the peak punch-through penetration (qpeak) resistance of a spudcan on sand overlying clay. A series of loose sand overlying clay tests was performed and combined with an existing database of tests performed on dense sand overlying clay. The...

Interaction between hydrodynamics and salt marsh dynamics: An example from Jiangsu coast

Salt marshes are distributed along more than 400 km of the Jiangsu coast in Eastern China, which are regarded as important habitats and serve as coastal protection as well. Previous research has proven that salt-marsh vegetation can reduce current velocity and dampen waves by its stems and leaves. Reversely, hydrodynamic forces also have a...

Wing flexibility effects in clap-and-fling

The work explores the use of time-resolved tomographic PIV measurements to study a flapping-wing model, the related vortex generation mechanisms and the effect of wing flexibility on the clap-and-fling movement in particular. An experimental setup is designed and realized in a water tank by use of a single wing model and a mirror plate to...

Recycling of WEEE by magnetic density separation

The paper introduces a new recycling method of WEEE: Magnetic Density Separation. By using this technology, both grade and recovery rate of recycled products are over 90%. Good separations are not only observed in relatively big WEEE samples, but also in samples with smaller sizes or electrical wires.

A Rule-Based System for Contextualized Information Delivery

When carrying out tasks, police officers need up-to-date information contextualized to their current situation to support them in decision making. The results of a previous user study with the aim of capturing the information requirements of police officers have led to the implementation of a rule-based system for contextualized information...

Improved Situation Awareness for Public Safety Workers while Avoiding Information Overload (extended abstract)

This research stems from the MOSAIC project, a part of the valorization and knowledge transfer effort of the Interactive Collaborative Information Systems (ICIS) research programme (http://www.icis.decis.nl/), supported by the Dutch Ministry of Economic Affairs, grant no.: BSIK03024. ICIS is hosted by the D-CIS Lab (http://www.decis.nl/), the...

Modelling of turbulent jets and wall layers: Extensions of Lighthill's acoustic analogy with applications to computational aeroacoustics

Two extensions to Lighthill's aeroacoustic analogy are presented. First, equivalent sources due to initial conditions are derived that supplement those due to boundary conditions, as given by Ffowcs Williams & Hawkings. The resulting exact inhomogeneous wave equation is then reformulated with pressure rather than density as the wave variable,...
