Many low-lying densely populated areas and important economical regions in Europe are threatened by sea level rise. \cite{groeskamp2020need} suggest an international cooperation to be able to protect these areas if climate change mitigation fails: the construction of the Northern European Enclosure Dam (NEED). In this research first order...

The present paper investigates the architectural meaning and importance of borders in the context of increased European cooperation. The question is investigated through the case study of the trinational border area in the metropolitan region of Basel, where Switzerland, Germany and France meet. The central theme propelling the discussion is the...

Cancers are characterized by extensive heterogeneity that occurs intratumorally, between lesions, and across patients. To study cancer as a complex biological system, multidimensional analyses of the tumor microenvironment are paramount. Single-cell technologies such as flow cytometry, mass cytometry, or single-cell RNA-sequencing have...

Theories from psychology or the social sciences are commonly used as a starting point when designing persuasive technologies that aim to evoke a specific behavior change. Ideally, using these theories would (1) help guide the design of the persuasive technology and (2) help evaluate and inform the theory. In this paper, we focused on the first...

The defomation of a vortex sheet behind a 30 degrees swept back wing, has been measured in a low-speed wind tunnel. The measurements included: - A total-head survey behind the wing, - Sidewash measurements across the wake, - Measurements of trailing vorticity by a vortex indicator. It has been found, that 60 percent of the trailing vorticity is...

The commonly used blade-element theory predicts a zero yawing moment in the time-average sense. Small-scale wind-tunnel experiments at the Eindhoven University of Technology revealed stable yawing moments at almost all operating conditions with the rotor in an upwind position with respect to the tower. The present comment shows, that this...

Research on high-lift devices has been carried out at NLR along the following lines. An experimental approach consisting of pressure measurements at the mid-span section of a twodimensional wing (chord about 0.6 m, span 2 m), with boundary layer control at the tunnel wallwing junctions by blowing slots. Premature flow separation can be avoided...

Processes on degradation and aggradation of rivers have a speed depending on the characteristics of the rivers. Starting from the basic equations a morphological timescale, characterising these processes, is defined. This morphological time-scale is estimated for various rivers.

Often the need is felt to schematize a river regime by one single discharge, the Dominant Discharge, and to use this discharge for prediction of changes in a riverstretch as a consequence of riverworks. This article discusses some methods, as given in literature, to determine the Dominant Discharge and gives a way to compute this discharge by...

A two-bladed horizontal-axis wind turbine, with a diameter of 0.75 m and a solidity ratio of 0.0674, has been tested in the LST 3 x 2 of NLR. Most of the tests have been carried out at an almost constant Reynolds number of about 3.5 X 10/5. Comparison with a simple performance prediction method showed an acceptable agreement in qualitative...
