Werthmüller, D. (author), Mulder, W.A. (author), Slob, E.C. (author)3-D controlled-source electromagnetic data are often computed directly in the domain of interest, either in the frequency domain or in the time domain. Computing it in one domain and transforming it via a Fourier transform to the other domain is a viable alternative. It requires the evaluation of many responses in the computational domain if...journal article 2021

(author), Pourteimouri, Paran (author)The long-term physical existence of sandy shores critically depends on a balanced sediment budget. From the principles of Building with Nature it follows that a sustainable protection of sandy shores should employ some form of shore nourishment. In the spatial design process of urbanized sandy shores, where multiple functions must be integrated,...journal article 2021

van Baelen, D. (author), van Paassen, M.M. (author), Ellerbroek, Joost (author), Abbink, D.A. (author), Mulder, Max (author)Modern aircraft can be equipped with a flight envelope protection system: automation which modifies pilot control inputs to ensure that the aircraft remains within the allowable limits. Overruling the pilot inputs may lead to mode confusion, even when visual or auditory feedback is provided to alert pilots. We advocate using active control...journal article 2021

van Bergen, J. (author), Mulder, J. (author), Nijhuis, S. (author), Poppema, D. (author), Wijnberg, K. (author), Kuschnerus, M. (author)Sandy shores worldwide suffer from coastal erosion due to a lack of sediment input and sea-level rise. In response, coastal sand nourishments are executed using ‘Building with Nature’ techniques (BwN), in which the sand balance is amplified and natural dynamics are instrumental in the redistribution of sand, cross- and alongshore. These...journal article 2021

Mulder, W.A. (author)ABSTRACTWhen modeling wave propagation, truncation of the computational domain to a manageable size requires nonreflecting boundaries. To construct such a boundary condition on one side of a rectangular domain for a finite-difference discretization of the acoustic wave equation in the frequency domain, the domain is extended on that one side to...journal article 2021

van den Boomen, M. (author), Van der Meulen, Sjoerd (author), Van Ekris, Jonathan (author), Spanjers, Roel (author), Ten Voorde, Olle (author), Mulder, Janwin (author), Blommaart, Peter (author)<br/>The port of Rotterdam is the largest seaport in Europe. To maintain its position, the harbor will have to anticipate global transitions such as transferring to sustainable energy. Hydrogen is seen as a promising energy carrier; however, future demand is uncertain. The current research investigates decision making under uncertainty and...journal article 2021

Weninger, B. (author), Thijs, M.A. (author), Nijman, Jeroen A.C. (author), van Eijck, L. (author), Mulder, F.M. (author)Iron is a promising, earth-abundant material for future energy applications. In this study, we use a neutron diffractometer to investigate the properties of an iron electrode in an alkaline environment. As neutrons penetrate deeply into materials, neutron scattering gives us a unique insight into what is happening inside the electrode. We made...journal article 2021

Mangel Raventos, A. (author), Kluivers, Gerard J. (author), Haverkort, J.W. (author), de Jong, W. (author), Mulder, F.M. (author), Kortlever, R. (author)Both daily and seasonal fluctuations of renewable power sources will require large-scale energy storage technologies. A recently developed integrated battery and electrolyzer system, called battolyser, fulfills both time-scale requirements. Here, we develop a macroscopic COMSOL Multiphysics model to quantify the energetic efficiency of the...journal article 2021

Dijkhuis, Edwin (author), Mulder, K.B. (author), Lubelli, B. (author)Aan de zuidwestzijde van de binnenstad van Breda ligt de deels gedempte rivier de Mark. Deze wordt de komende jaren uitgegraven en getransformeerd tot een blauwgroene ader: de Nieuwe Mark. De Nieuwe Mark moet straks de lokale ecologie verstevigen en het stedelijk klimaat verbeteren. Onderdeel van deze natuurinclusieve transformatie is het...journal article 2021

Iranzo, A. (author), Mulder, F.M. (author)The transition to renewable electricity sources and green feedstock implies the development of electricity storage and conversion systems to both stabilise the electricity grid and provide electrolytic hydrogen. We have recently introduced the concept of a hybrid Ni/Fe battery-electrolyser (battolyser) for this application1. The hydrogen...journal article 2021

Poppema, Daan W. (author), Wijnberg, Kathelijne M. (author), Mulder, Jan P.M. (author), Vos, S.E. (author), Hulscher, Suzanne J.M.H. (author)In sandy environments, like the beach-dune system, buildings not only affect the airflow, but also the aeolian sediment transport in their surroundings. In this study, we determine how the horizontal size of sediment deposition patterns around buildings depends on the building's dimensions. Four one-day experiments were conducted at the beach...journal article 2021

(author), Snik, Frans (author), Stam, D.M. (author)Context. Homochirality is a generic and unique property of life on Earth and is considered a universal and agnostic biosignature. Homochirality induces fractional circular polarization in the incident light that it reflects. Because this circularly polarized light can be sensed remotely, it can be one of the most compelling candidate...journal article 2021
