In numerical modelling of water movement wetting and drying is a well known problem. The governing equations are not valid in the dry part of the computational domain which may result in problems with mass conservation, negative water depths and artificially enlarged gradients. A method is proposed that allows for the surface elevation to become...

Het toepassingsgebied van extracties met nabij- en superkritische gassen, pas in het laatste decennium op industriële schaal beperkt toegepast, is nog niet geheel afgebakend. Van recente datum is een nieuw proces met warmte­pomp voor nabijkritische extractie met propaan van ethanol­ water mengsels, waardoor zuiver ethanol wordt geproduceerd ...

In Madurodam ligt een modelspoorbaan (schaal 1:25) die eigendom is van de N.V. Nederlandse Spoorwegen.<br/> In verband met de economische veroudering van de installatie heeft de NS besloten deze te vernieuwen. Omdat ook de wens aanwezig was de nu nog met de hand geregelde treinenloop te automatiseren is de NS een samenwerkingsverband aangegaan...

The Hydraulics division (WT) in The Hague, part of het Delta department, consists of 5 production-departments that execute the so-called "advising-proces" , i .e. they support the Deltaworks by supervising and carrying out technica1 studies. Today their planning and accounting system (PLAC) is mainly a partial and uniform time-accounting- system...

In this report, a mathematical model for rectifying Side Looking Airborne Radar images in the preprocessing stage is presented. The model holds for flat terrain. Input for this model are radardata, consisting of recorded resolution cells and flight path data, originating from an Inertial Navigation System onboard the aircraft. Output of the...
