Mulder, W.A. (author)Recently introduced non-reflecting boundary conditions are numerically exact: the solution on a given domain is the same as a subset of one on an enlarged domain where boundary reflections do not have time to reach the original domain. In 1D with second- or higher-order finite differences, a recurrence relation based on translation invariance...conference paper 2021

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

Buckenmayer, M.B. (author), Gonçalves, M. (author), Mulder, I. (author)Social innovations are promising to tackle today's complex global challenges, especially when they scale, leading to a higher impact, which can generate asocietal transformation. The current work elaborates on scaling deep, a specific scaling strategy aiming to shift cultural values, mindsets and beliefs. However, applying this strategy in...conference paper 2021

Buckenmayer, M.B. (author), Gonçalves, M. (author), Mulder, I. (author)“Off to new shores!” is a two-hour, interactive online workshop, participants will sail together to common ground and co-create a shared understanding of central concepts regarding a provided case. Participants learn and apply the concept of fruitful friction and use the metaphor of sailing. Fruitful friction is a concept that deliberately...conference paper 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

(author), Mulder, Max (author)In the analysis of human performance and human error, considerable attention is given to the cognitive processes of actors involved in error or success scenarios. Even with awareness of hindsight bias, it takes effort to understand the actions of agents in later inspection of error scenarios. One such topic of heated discussion was the perceived...conference paper 2021

Ruan, J. (author), Ghose, R. (author), Mulder, W.A. (author)Induced seismicity from a gas-producing region such as Groningen is believed to be caused by reservoir depletion due to long-term gas production. However, because of the complexity and uncertainty regarding the underground structure and composition, it is difficult to quantify the effect on induced seismicity due to gas production. Here we use...poster 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

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
