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; …

The tidal area in the Eastern Scheldt is decreasing because of sand erosion and sea-level rise. Therefore, Rijkswaterstaat has investigated the possibilities to mitigate the consequences of erosion to maintain the intertidal areas. The height of the Galgeplaat tidal flat, the second-largest tidal flat …

Knowledge of spatial and temporal trends in the environmental exposure to radiofrequency electromagnetic fields (RF-EMF) is a key prerequisite for RF-EMF risk assessment studies attempting to establish a link between RF-EMF and potential effects on human health as well as on fauna and flora. In this …

Het doel van dit proefschrift was om spierkracht en vrijwillige spieractivatie te bestuderen die het functioneren kunnen belemmeren in ouderen met artrose. Artrose is een gewrichtsaandoening die gekenmerkt wordt door slijtage van gewrichten. Vooral mensen met artrose aan de knie of heup ondervinden problemen …

INTRODUCTION: The interpolated twitch technique is often used to assess voluntary activation (VA) of skeletal muscles. We investigated VA and the voluntary torque-superimposed torque relationship using either supramaximal nerve stimulation or better tolerated submaximal muscle stimulation, which is often …
