Vacuum-Assisted wound care (VAC) is effective for treating complex wounds, but is hardly available in low-resource settings. An affordable, portable and safe VAC device was developed to treat patients with chronic and complex wounds: the Wound Care (WOCA) Pump. The WOCA safely controls the pressure accurately (+/- 10%) between -70 and -125 mmHg...

In The Netherlands, inspection and maintenance are essential for maintaining stringent flood protection standards. Flood defences are assessed every 12 years to ensure they meet their risk-based safety standards,which are given as legally-binding maximum failure probabilities. Between assessments, flood defence managers are subject to risk...

We present new experimental data concerning the statistics of heavy and light particles dispersed at low concentrations in a homogeneous turbulent shear flow. Information on both the spatial distribution and on the relative velocity of the dispersed phases is obtained by accurate three-dimensional optical measurements, and will allow to...

The economic consequences of floods, both in the form of material damage and losses due to business interruption, can be large. This paper presents a comparison between two approaches to determine the losses due to business interruption caused by large-scale floods. A model (HIS-SSM) containing a damage function approach and an Adaptive Input...

Zowel in nationaal als in trilateraal verband geldt als één van de ecologische doelen voor de Waddenzee een zo groot en natuurlijk mogelijk areaal aan kwelders. Actief ingrijpen om bestaande kwelders in stand te houden dient op een zo natuurlijk mogelijke wijze plaats te vinden. In de kwelderwerken en zomerpolders langs Friese en Groninger...

De uitkomsten van de berekeningen met de additionele stochasten voor ongeveer 50 waterkeringen in Nederland laten zien dat de waterstanden en golfcondities hoger/zwaarder uitpakken dan het referentieniveau (huidige methode). Dit is niet verrassend. Toevoegen van extra onzekere factoren leidt bijna altijd tot hogere verwachtingswaarden, omdat de...

Nowadays various digital television services are available. However, the user of these services experiences longer delays than the traditional analog TV while switching from channel to channel. The digital TV operator usually displays a black screen with the channel number during zapping. However, it could be interesting for the TV viewer, if...

In an earlier paper we showed, that perceived quality of channel zapping is related to the perceived quality of download time of web browsing, as suggested by ITU-T Rec.G.1030. We showed this by performing subjective tests resulting in an excellent fit with a 0.99 correlation. This was what we call a lean forward experiment and gave the rule of...

In de Waddenzee liggen langs de noordkust van het vasteland van Groningen en Friesland 6000 ha voormalige landaanwinningswerken. Door middel van sturing van de natuurlijke processen zijn daarin halfnatuurlijke kwelders gevormd. De kwelderwerken zijn door middel van rijshoutdammen en begreppeling gecreëerd en de kweldervegetatie heeft zich...

Currently a new generation Test and Verification Equipment (TVE) is being developed under ESA contract as successor "to the Test and Simulation Assembly (TSA) for a Modular Attitude Control System (MACS). It will be a modular system that can be tailored for any Attitude and Orbit Control Subsystems (AOCS). The gained experience with complex AOCS...

The infrared Astronomical Satellite IRAS is equipped with an on-board computer system that takes care of vital satellite functions as attitude control, ground dialogue and execution of the observation programs. Therefore an important purpose of the IRAS system tests was the Verification and Validation of the on-board software. The test...
