Kounalakis, M. (author), Gottardi, Luciano (author), De Wit, Martin (author), Blanter, Y.M. (author)We theoretically predict and experimentally observe the onset of weak-link physics in the dynamical response of transition-edge sensors (TESs). We develop a theoretical framework based on a Fokker-Planck description that incorporates both the TESs electrical response, stemming from Josephson phenomena, and the electrothermal effects due to...journal article 2023

(author)We have measured and characterized the thermal crosstalk in two different arrays of transition-edge sensor (TES) X-ray microcalorimeters with frequency-domain multiplexing (FDM) readout. The TES arrays are fabricated at SRON and are a 8 × 8 and a 32 × 32 'kilo-pixel' uniform array. The amount of crosstalk is evaluated as the ratio between the...journal article 2022

(author), Vaccaro, Davide (author), De Vries, Cor P. (author), De Wit, Martin (author), Hoogeveen, Ruud W.M. (author), Gao, J.R. (author)We are developing a kilo-pixels Ti/Au TES array as a backup option for Athena X-IFU. Here we report on single-pixel performance of a 32 × 32 array operated in a Frequency Division Multiplexing (FDM) readout system, with bias frequencies in the range 1-5 MHz. We have tested the pixels response at several photon energies, by means of a 55Fe...journal article 2021

De Wit, F.P. (author)Alongshore currents are currents parallel to the coastline. In coastal areas they are driven by a combination of wave and tidal forcing. In this study, the validity of the non-hydrostatic, wave-flow model SWASH to predict these currents is investigated. This is done by comparing model predictions with measurement observations. Observations were...master thesis 2016

Huibregtse, E. (author), Morales Napoles, O. (author), Hellebrandt, L. (author), Paprotny, D. (author), De Wit, S. (author)This paper presents a risk-based method to quantify climate change effects on road infrastructure, as a support for decision-making on interventions. This can be implemented in climate adaptation plans as an element of asset management. The method is illustrated by a specific case in which traffic on a road network is disrupted by the flooding...journal article 2016

Van der Velde, J.R.T. (author), De Wit, S.I. (author)The appreciation of green infrastructures as ‘nature’ by urban communities presents a critical challenge for the green infrastructure concept. While many green infrastructures focus on functional considerations, their refinement as places where concepts of nature are represented and where nature can be experienced and understood, has received...book chapter 2015

In porous media, a stratification of a given solution on top of another miscible solution can be buoyantly unstable because of an unstable density stratification or because of differential diffusive effects. The former is the well known Rayleigh–Taylor (RT) mechanism wherein the interface is destabilized by the denser solution overlying a less...conference paper 2015

Radermacher, M. (author), De Wit, L. (author), Uijttewaal, W.S.J. (author), Winterwerp, J.C. (author)When dredging in sensitive environments, efforts have to be made to limit the free dispersal of suspended fine sediment from the dredging spill. Especially the use of hanging silt curtains as an environmental mitigation measure is widespread. Despite frequent application, their ability to reduce turbidity levels through vertical diversion of...journal article 2015

De Wit, L. (author)3D CFD simulations, lab experiments and field measurements are used to get more understanding of the turbulent near field overflow dredging plume mixing. The focus has been on the most often used dredging vessel: a trailing suction hopper dredger (TSHD). Near field overflow dredging plume mixing is important because it determines the far field...doctoral thesis 2015

Heineke, D. (author), Volbeda, E. (author), De Weerdt, B. (author), De Wit, F. (author)Due to frequently occurring storms, like hurricanes and cold fronts, the coasts around the Mexican port city Veracruz suffer from erosion. This is most severe at the beaches of Boca del Rio just south of the city of Veracruz. Here, small beaches can be found between large groynes. These groynes block the southward littoral drift significantly...student report 2014

De Wit, S.I. (author)What bearing can the expression of ‘place’ have on the ‘placeless geography’ of the suburban metropolis? Unravelling the design of the Wasserkrater garden, designed by Agence Ter between 1997 and 2000, points towards a possible reconnection between suburban metropolis and genius loci, the essence of the place.book chapter 2014

Radermacher, M. (author), Van der Goot, F. (author), Rijks, D.C. (author), De Wit, L. (author)One of the potential environmental issues associated with dredging in the marine environment is the increase of suspended sediment concentrations (SSC) by generation and dispersion of sediment plumes. This can be mitigated by source control or by the installation of containment barriers like silt screens. This article focusses on hanging silt...journal article 2013
