Dummer, A (author), Poelma, C. (author), DeRuiter, M.C. (author), Goumans, M-J TH (author), Hierck, BP (author)Background<br/>Primary cilia are cellular protrusions involved in mechanic and chemical sensing on almost all cells of our body. Important signaling pathways, including Hedgehog, TGFβ, and Ca2+, are linked to cilia and/or cilia function. Cilia can vary in length, which has functional implications. To measure these lengths correctly, a...journal article 2016

Lancelot, P.M.G.J. (author), De Breuker, R. (author)This paper presents the results from the equivalent static load method applied to gust response optimisation of an aircraft wing. Through the different optimisation runs, it is assessed that gust load cases can be critical and are difficult to constrain with the sole use of static load cases. Several cases are evaluated with different gust...conference paper 2016

Lancelot, P.M.G.J. (author), De Breuker, R. (author)This paper summarises a conceptual study regarding a passively actuated spoiler for gust load alleviation. The design of such system is intended to limit the use of computers, sensors and actuators to operate the device. The study mainly relies on using Theodorsen’s unsteady flow theory for a typical airfoil section. To cope with the limitations...conference paper 2016

Malgoezar, A.M.N. (author), Snellen, M. (author), Sijtsma, P. (author), Simons, D.G. (author)Assigning proper positions to microphones within arrays is essential in order to reduce or eliminate side- and grating lobes in 2D beamform images. In this paper an objective function is derived providing a measure for the presence of artificial sources. Using the global optimization method Differential Evolution an optimized microphone...conference paper 2016

Sijtsma, P. (author), Snellen, M. (author)In this paper a high-resolution extension of CLEAN-SC is proposed: HR-CLEAN-SC. Where CLEAN-SC uses peak sources in “dirty maps” to define so-called source components, HR-CLEAN-SC takes advantage of the fact that source components can likewise be derived from points at some distance from the peak, as long as these “source markers” are on the...conference paper 2016

Morriea-Matias, Luis (author), Cats, O.

In contrast to automated passenger counts systems, automated vehicle location (AVL) data are often available for the entire public...journal article 2016

Gentile, V. (author), Schrijer, F.F.J. (author), van Oudheusden, B.W. (author), Scarano, F. (author)The backflow instability in the wake past a cylindrical blunt-based body in pitch is investigated at a Reynolds number ReD = 6.7 · 104 based on the cylinder diameter. Time-resolved stereoscopic particle image velocimetry measurements have been performed in a cross-flow plane located 0.3 D downstream of the model base. An increasing displacement...conference paper 2016

Gentile, V. (author), Schrijer, F.F.J. (author), van Oudheusden, B.W. (author), Scarano, F. (author)The so-called very-low-frequency (VLF) azimuthal meandering of the reversed-flow region has been shown to contribute significantly to the unsteadiness of the turbulent wake flow past a bluff body of revolution (Rigas et al. 2014; Grandemange et al. 2014). Such an erratic behavior causes a continuous change in the wake topology and, particularly...conference paper 2016

van Hal, J.D.M. (author)Everyone acknowledges the importance of sufficient financial resources and wellfunctioning technologies when it comes to renovation processes with energy ambitions. However, Dutch experiences show that these two factors alone do not automatically result in success. More is needed, and this ‘more’ has to do with less concrete, but in the existing...conference paper 2016

Luteijn-Nava Guerrero, G.D.C. (author), Schwarz, P. (author), Slinger, J (author)Modelling and simulation aim to reproduce the structure and imitate the behavior of real-life systems. For complex dynamic systems, System Dynamics (SD) and Agent-based (AB) modelling are two widely used modelling paradigms that prior to the early 2010’s have traditionally been viewed as mutually exclusive alternatives. This literature review...conference paper 2016

Klein, Raphael (author), Meeuwsen, Sjoerd (author), Slinger, J (author)Flood defences are a key issue in low lying coastal areas. These defences can protect the economy of hinterland regions along with countless lives. A onceptually simple abstraction of the complexity of a flood defence system is formulated in system dynamics. This model is based on a ring dike concept as used in The Netherlands. The model is...conference paper 2016

Clifford Holmes, J.K.V. (author), Pollard, S (author), Biggs, H (author), Chihambakwe, Kundai (author), Jonker, Willem (author), York, Theo (author), Andres Diaz, Fabio (author), Slinger, J (author)In this paper, we report on a concerted modelling effort in the South African water resources sector in which system dynamics provides the paradigmatic framing for both a stakeholder engagement process and for developing an underpinning, integrative simulation model. We describe the design of the parallel modelling approach and examine the...conference paper 2016

van der Hoeven, F.D. (author)Starchitect Zaha Hadid won the bid to design one of the planned stadiums for the 2022 FIFA World Cup event in Qatar. Her design for the Al-Wakrah stadium became the centrepiece of a discussion on the role that starchitects play in society. That debate reached a boiling point in August 2014, and resulted in a digital lynching party that sheds...journal article 2016

Palmboom, F.J. (author)Urban design in the context of delta landscapes is quite a challenge. By nature, deltas are highly dynamic environments. Despite all the risks they pose to people, over many centuries they have provided favorable conditions for intensive agriculture and human habitation. Always heavily used, in our time deltas throughout the world are coming...book chapter 2016

Meyer, Han (author)The position of the Netherlands as a highly urbanized delta region is by no means unique in the world. Far from it. In fact, all around the world, deltas are sites of strong urban and economic growth. What is unique about the Netherlands, however, is the high level of flood protection, which has ensured that no serious flooding disaster has...book chapter 2016

Palmboom, F.J. (author)The IJsselmeer, or Lake IJssel, represents the northern flank of the Dutch Delta. In several aspects, this region is quite different from the South West Dutch Delta and the Rotterdam Rijnmond region. For one thing, as a delta landscape, it is less dynamic then the other two delta regions. Also, as an urbanized area dominated by the city of...book chapter 2016
