Multi-faceted tasks can be completed in a linear start-to-finish fashion, or by completing the different facets parallel to each other. Either way, at some point the final additions and adjustments are made such that all the pieces fit together, and the task is completed properly. For example, baking …

This article discusses results from an international contest, open for university student teams (bachelor and master), involving the design, construction, and testing of small wind turbines in a large wind tunnel. The wind tunnel has an outlet of 2.85 x 2.85 m allowing a maximum rotor swept area of 2 …

Radio Kootwijk is part of Dutch history, and the impressive main Building A stands as a monument of architecture and communication in the heaths of the Veluwe near Apeldoorn. But both building and nature are in peril since preservation only is not enough to meet new standards for upkeep and improvement. …

Many neighborhoods dating from the 1970s, with corporation-owned terraced housing in open urban schemes, saw a round of renovation for the houses in the last decades, but left the supply of family homes intact. This housing stock doesn’t meet the needs of the elderly still living in them anymore, nor …

The dynamic inflow effect describes the unsteady aerodynamic response to fast changes in rotor loading due to the inertia of the wake. Fast changes in turbine loading due to pitch actuation or rotor speed transients lead to load overshoots. The phenomenon is suspected to be also relevant for gust situations; …

Er is steeds meer behoefte om data veilig tot in het end-point apparaat te brengen. Ook wel zerotrust networking genoemd. Daarnaast groeien de dreigingen. Zo geven de recente kwetsbaarheden in de hardware van pc-platformen voldoende aanleiding om niet meer volledig op de softwarescheiding van besturingssystemen …

The native fish populations in New Zealand have proven to be declining. There are various reasons for this change in population size, one of the biggest being structures that form barriers to migration. This shows the need for fish passage options that are better adjusted to these ‘weaker’ swimmers and …

Sub-scale Flight Testing (SFT) is potentially useful in predicting aircraft flight behaviour, especially in the case of unconventional designs for which legacy information is unavailable and wind tunnel tests are unable to predict aircraft dynamics. A necessary condition for SFT is the design of properly …
