This paper assesses wind resource characteristics and energy yield for micro wind turbines integrated on noise barriers. An experimental set-up with sonic anemometers placed on top of the barrier in reference positions is realized. The effect on wind speed magnitude, inflow angle and turbulence intensity …

De Nederlandse Aardolie Maatschappij behandelt gewonnen gas op locatie Anjum. Op deze gasbehandelingslocatie wordt het gas afkomstig uit de gasputten Lauwersoog en Moddergat tot zeer lage temperaturen gekoeld, zodat bepaalde kwaliteitsspecificaties van het gas worden behaald. Om te voorkomen dat de …

Initial investigations into the use of a MEMS based multi-parameter sensor for the characterization of medicine mixtures …

Stormwater runoff has severe negative and direct impact on the quality of surface waters and groundwater. The impact can cause chemical and heavy-metal pollution. Applying well established methods to map pollutants in urban areas and specifically in Nature-Based Solutions (NBS), such as Sustainable Urban …

To avoid energy scarcity as well as climate change, a transition towards a sustainable society must be initiated. Within this context, governmental bodies and/or companies often note sustainability as an end goal, for instance as a green circular economy. However, if sustainability cannot be clearly …

Due to lack of proper stormwater drainage in the Waymouth Hills, stormwater runoff have often caused undermining of the road infrastructure and disrupting traffic flow in the study area. Sediments are often deposited to the low-lying terrain from the runoff and this reduces the storm drains capacity …

Introduction In the harbor of Zierikzee there is a strong tidal influence. The difference between the water levels during high and low tide lies around the three meters. The harbors De Oude Haven and ‘T Sas fall dry during an extremely low tide. When these harbors fall dry, foundations will come in …

The Southwest Delta is a dynamic area where three of the largest rivers in the Netherlands flow out into the North Sea. The area is internationally famous for its natural values, but nature and human interventions have difficulty co-existing. A healthy delta can support functions that humans derive from …

We report on a first field test in which miniaturized sensor motes were used to explore and inspect an operational pipeline by performing in situ measurements. The spherical sensor motes with a diameter of 39 mm were equipped with an inertial measurement unit (IMU) measuring 3-D acceleration, rotation, …

A novel type of application for the exploration of enclosed or otherwise difficult to access environments requires large quantities of miniaturized sensor nodes to perform measurements while they traverse the environment in a “go with the flow” approach. Examples of these are the exploration of underground …
