Vercruyssen, N. (author), Verhagen, T.G.A. (author), Flokstra, M.G. (author), Pekola, J.P. (author), Klapwijk, T.M. (author)We study the nonlinear response of current transport in a superconducting diffusive nanowire between normal reservoirs. We demonstrate theoretically and experimentally the existence of two different superconducting states appearing when the wire is driven out of equilibrium by an applied bias, called the global and bimodal superconducting states...journal article 2012

Lam, N.T. (author), Verhagen, H.J. (author), Van der Wegen, M. (author)This paper presents an application of an one-dimensional unsteady numerical model DUFLOW for hydrodynamic simulation of a complex lagoon-inlet system in Vietnam. The difficulties due to the lack of data for model boundary conditions is overcome by using sensitivity analysis approach for the uncertainties of boundary conditions. Model results are...journal article 2004

Tuan, T.Q. (author), Verhagen, H.J. (author), Visser, P.J. (author), Stive, M.J.F. (author)To increase physical insight into wave overwash processes at low-crested beach barriers, wave overtopping discharge events rather than the conventional average overtopping discharge need to be quantified. Also, in order to make intelligent use of the many empirical formulations on wave overtopping discharge at breakwaters from literature, a...journal article 2006

Verhagen, H.J. (author)Sand waves, defined as longshore wave-like movements of the shoreline, measured in a horizontal plane, are described along several stretches of the shoreline of The Netherlands. They have a celerity in the order of 50-200 m/yr, a period of 50- 150 years and an amplitude of 30- 500 m. They are found along the whole Dutch shoreline. Analysis of...journal article 1989

Verhagen, H.J. (author)Because dunes protect a large part of The Netherlands against coastal flooding and inundation, it is vital to guarantee the strength of these natural sea defenses. Besides sea defense, dunes have other functions. Sandy shorelines and dunes are frequently eroded. A legal framework has been developed that guarantees the required safety-level of...journal article 1990

Verhagen, H.J. (author), Maranus, J.W. (author)Langs de Zeeuwse kust bewegen grote massa's zand van zuid naar noord. Deze zandgolven zorgen voor een cyclisch kustgedrag. Bij de besluitvorming over kustverdedigingswerken en strandsuppleties is inzicht in de kinematica van deze golven essentieel.journal article 1987

Verhagen, H.J. (author), Struik, P. (author)Tegenwoordig is bijna elk probleem bij de versterking van dijken op te lossen door een kunstwerk te maken in plaats van de traditionele grondconstructie. Soms wordt bij de afweging te weinig rekening gehouden met de lange levensduur en de bijzondere aard van' de waterkering'. Dat kan toekomstige generaties met grote problemen opzadelen.journal article 1993

Lam, N.T. (author), Stive, M.J.F. (author), Wang, Z.B. (author), Verhagen, H.J. (author), Thuy, V.T.T. (author)Hydrodynamics and morphodynamics of a seasonally forced tidal inlet system are investigated using numerical models. The ocean forcing including tidal and wave actions and sediment transport is simulated using Delft3D model. Fluvial processes in Delft3D are taken into account as results from SOBEK RURAL model. Analysis of the numerical simulation...journal article 2008

Tuan, T.Q. (author), Stive, M.J.F. (author), Verhagen, H.J. (author), Visser, P.J. (author)A new process-based approach is introduced for a more efficient computation of the overflow-induced growth of an erosional channel in a noncohesive homogeneous narrow landmass such as the breach growth in a sand-dike. The approach is easy to incorporate in a 1D/2DV morphodynamic model to compute the channel growth both vertically and laterally....journal article 2008

Hoan, N.T. (author), Stive, M.J.F. (author), Booij, R. (author), Hofland, B. (author), Verhagen, H.J. (author)This paper presents the results of an experimental study on stone stability under nonuniform turbulent flow, in particular expanding flow. Detailed measurements of both flow and turbulence and the bed stability are described. Than various manners of quantifying the hydraulic loads exerted on the stones on a bed are extensively reviewed and...journal article 2011

Verhagen, B. (author), Celebi, T. (author)The International Space Station (ISS) celebrated its 15th birthday in October 2013. The ISS is the largest spaceship ever built by humans and very important for research, to understand life and physics. However, the ISS is very expensive to maintain and therefore some people argue that the ISS program should stop. The US president has decided to...journal article 2014

(author)Atherosclerotic plaque composition can indicate plaque vulnerability. We segment atherosclerotic plaque components from the carotid artery on a combination of in vivo MRI and CT-angiography (CTA) data using supervised voxelwise classification. In contrast to previous studies the ground truth for training is directly obtained from 3D registration...journal article 2014

(author), Linn, S.C. (author)Breast cancers with BRCA1 germline mutation have a characteristic DNA copy number (CN) pattern. We developed a test that assigns CN profiles to be ‘BRCA1-like’ or ‘non-BRCA1-like’, which refers to resembling a BRCA1-mutated tumor or resembling a tumor without a BRCA1 mutation, respectively. Approximately one third of the BRCA1-like breast...journal article 2015

Gu, D. (author), Verhagen, H.J. (author), Van de Ven, M. (author)PUR-revetment is a newly developed method for hydraulic application. Its structure is similar to that of open stone asphalt revetment, but the crushed stones are glued by polyurethane (PUR) instead of bitumen. To study the feasibility of applying PUR-revetment, a research based on the comparisons between PUR-revetment and open stone asphalt...journal article 2008

Trung, L.H. (author), Van der Meer, J.W. (author), Verhagen, H.J. (author)Little is known about the strength of the land-side slopes of the Vietnamese sea dikes under overtopping attack. Some grass-covered slopes were tested by a wave overtopping simulator. The paper describes the simulator and presents the test results. The tested grass covers could withstand overtopping rates varying from 20 l/s to 100 l/s per meter...journal article 2014
