Drukvereffening beter begrepen (2). Resultaten volleschaalmeting woontoren New Orleans in Rotterdam

De windbelasting op gevelsystemen wordt mede bepaald door de detaillering van het gevelsysteem. Wanneer de gevel bestaat uit een meerlaagse constructie met een luchtdicht binnenblad, een spouw en open voegen in de buitenste laag, kan drukvereffening optreden. De mate van drukvereffening heeft consequenties voor de belasting op het buitenblad. In...

An automated day-time cloud detection technique applied to MSG-SEVIRI data over Western Europe

Since February 2003, the Spinning Enhanced Visible and Infrared Imager (SEVIRI) aboard the first Meteosat Second Generation (MSG) satellite has provided radiance data in 12 spectral bands for a full Earth hemisphere every 15 minutes. This high frame rate renders it an excellent tool for studies of atmospheric transport of pollutants, aerosol and...

An alternative approach to estimate the W/C ratio of hardened concrete using image analysis

The water cement (w/c) ratio is a typical quality parameter for concrete. The NT Build 361 Nordtest method is a standard for estimating the w/c ratio in hardened concrete and is based on the relationship between the ilc ratio and the capillary porosity in the cement paste. The latter can be estimated using fluorescent light microscopy of...

Roadside versus in-car speed support for green wave: Driving simulator study

A green wave on a road enables a driver to negotiate a sequence of signalized intersections without hitting red. This is accomplished by the coupling of a series of signalized intersections. This is an advantage for driver comfort, for flow and safety on the road network, and for the environment. Providing speed advice may help the driver to...

Development of an algorithm for using weather-dependent dynamic speed limits to enhance safety

This paper describes an ongoing research project in the Netherlands for lowering the speed limit, depending on the weather condition (in particular rain) to enhance traffic safety. The research in this project consists of three main parts. In the first part, research has been conducted on the strategy of speed limits to be displayed: in what...

Influence of unexpected events on driving behaviour at different hierarchical levels: A driving simulator experiment

Computer based simulation models of human driving behaviour can be used effectively to model driving and behavioural adaptation to Intelligent Transport System (ITS). This can be a useful step in human centered design of ITS. To construct a comprehensive model of driving behaviour, the interaction between the three levels of the driving task has...
