Houd ruimte voor professionele gebiedsontwikkeling met water

‘Water en bodem sturend’ is op zich een goed uitgangspunt voor ruimtelijke inrichting. In de uitwerking dreigt dat echter meer ‘dicterend’ te worden, vinden Friso de Zeeuw en Ties Rijcken. Zij laten aan de hand van praktijkvoorbeelden zien hoe uitstekende gebiedsontwikkelingen dan kopje onder gaan, onder meer door vergaande juridisering.

Predicting and preventing in-plane shear induced fiber angle deviations during automated handling of non-crimp fabrics

Over the years the use of composites as an aircraft structural material has significantly increased. Currently, the industry still relies largely onmanually manufactured components. Automated manufacturing can however bring advantages such as reduced manufacturing costs and amore consistent and higher quality end product. An attractive automated...

The Green Intensive Care: From Environmental Hotspot to Action

Together we must reduce the impact of the healthcare sector and shift towards a circular economy. This paper describes the shift of three ICU environmental hotspots: gloves, gowns, and CRRT bags.

The effect of pick-up point location on fibre angle devation in Non-Crimp Fabrics

For pick-and-place processes to become widely implemented in industry a consistent and acceptable product quality needs to be achieved. One important quality criterion is the fiber angle deviations in the reinforcement. Handling a reinforcement will subject it to forces due to e.g. gravity and accelerations. These forces can result in in-plane...

Setting bounds for in-plane shear induced fiber angle deviations in bi-axial non-crimp fabrics

For pick-and-place processes to become widely implemented in industry a consistent and acceptable product quality needs to be achieved. In the state of the art it is assumed that reinforcements will be in perfect condition at the start of forming or draping. In reality the handling process can already result in undesired deformations. The...

Kabinet, zet in op een Nationale InvesteringsAgenda

Om de grote ruimtelijke opgaven waar Nederland voor staat aan te pakken, is het nodig dat rijksmiddelen gebundeld worden in een Nationale Investeringsagenda. (emeritus) hoogleraren Co Verdaas en Friso de Zeeuw vertellen waarom. "Een samenhangende aanpak is cruciaal om nationale en regionale middelen van publieke en private partijen gerichter en...

Strategies for swift automated pick-and-place operations of multiple large-sized layers of reinforcement - a critical review

For the application of composite materials to become more widespread and replace traditional materials their manufacturing processes and final products will need to be competitive and be e.g. lighter, stronger or stiffer and quicker, easier or more cost-efficient to produce than traditional materials. The state of the art for pick-and-place...

The Structure–Property Correlations in Dry Gelatin Adhesive Films

Gelatins are proteinaceous natural materials that are widely used in areas such as conservation and restoration of artifacts as adhesives and consolidants, in pharmaceutics as drug delivery carriers, and in the food industry as structurants. Herein, type A porcine gelatin adhesive films are prepared via solution casting method and their...

Quantification of nitrogen oxides emissions from build-up of pollution over Paris with TROPOMI

Nitrogen dioxide (NO₂) is a regulated air pollutant that is of particular concern in many cities, where concentrations are high. Emissions of nitrogen oxides to the atmosphere lead to the formation of ozone and particulate matter, with adverse impacts on human health and ecosystems. The effects of emissions are often assessed...

Adjoint-based adaptive convergence control of the iterative finite volume multiscale method

We propose a novel adaptive, adjoint-based, iterative multiscale finite volume (i-MSFV) method. The method aims to reduce the computational cost of the smoothing stage of the original i-MSFV method by selectively choosing fine-scale sub-domains (or sub-set of primary variables) to solve for. The selection of fine-scale primary variables is...

Iterative multiscale gradient computation for heterogeneous subsurface flow

We introduce a semi-analytical iterative multiscale derivative computation methodology that allows for error control and reduction to any desired accuracy, up to fine-scale precision. The model responses are computed by the multiscale forward simulation of flow in heterogeneous porous media. The derivative computation method is based on the...

Forms of privatization in Dutch urban development: From unsolicited proposals to private quality safeguarding

An unsolicited private proposal, a flexible masterplan and land-use plan, a quality team that overtakes the role of the public aesthetics commission, and private quality safeguarding for plan judgement and construction supervision. These instruments and agreements are used by housing association De Alliantie, the Municipality of Amsterdam, and...

Initial spreading of a mega feeder nourishment: Observations of the Sand Engine pilot project

Initial design of an LADM-based 3D Cadastre - Case study from Korea

Korea and The Netherlands have started a 3 year cooperation covering joint research, capacity building and international advisory in the domain of cadastre and land administration with a special focus on 3D developments. At the Korean side the Korea Cadastral Survey Corporation and the University of Seoul are involved, while at the Netherlands...

Impact of nourishments on nearshore currents and swimmer safety on the Dutch coast

Assessing swimmer safety along the Dutch coast entails more than only assessing the risk of rip currents. Seven criteria have been formulated to make a comprehensive assessment of swimmer safety along the Dutch coast. These are based on interviews with lifeguards, rescue report statistics and detailed lagrangian measurements of the current...
