Buijsrogge, A. (author), de Boer, Pieter-Tjerk (author), Scheinhardt, Werner R.W. (author)We consider importance sampling simulation for estimating the probability of reaching large total number of customers in an (Formula presented.) tandem queue, during a busy cycle of the system. Our main result is a procedure for obtaining a family of asymptotically efficient changes of measure based on subsolutions. We explicitly show these...journal article 2021

(author), Kašpar, Ondřej (author), Tokárová, Viola (author), Dirne, F. (author), Nicolau, Dan V. (author)Non-deterministic polynomial (NP-) complete problems, whose number of possible solutions grows exponentially with the number of variables, require by necessity massively parallel computation. Because sequential computers, such as solid state-based ones, can solve only small instances of these problems within a reasonable time frame, parallel...journal article 2021

Srinivasa Raja, A. (author), de Boer, Pascal (author), Giepmans, Ben N.G. (author), Hoogenboom, J.P. (author)Electron microscopy is crucial for imaging biological ultrastructure at nanometer resolution. However, electron irradiation also causes specimen damage, reflected in structural and chemical changes that can give rise to alternative signals. Here, luminescence induced by electron-beam irradiation is reported across a range of materials widely...journal article 2021

de Boer, Bas (author), Lemke, M. (author)Obesity has been pointed out as one of the main current health risks leading to calls for a so-called “war on obesity”. As we show in this paper, activities that attempt to counter obesity by persuading people to adjust a specific behavior often employ a pedagogy of regret and disgust. Nowadays, however, public healthcare campaigns that aim to...journal article 2021

Yang, Y. (author), de Boer, Ane (author), den Uijl, J.A. (author)A recent contest of shear tests modelling was carried out in 2019. Teams from universities and consultancies around Europe were invited to predict the shear capacity of two reinforced concrete beams. The basics of the numerical models were to be set up according the Dutch NLFEM Guideline RTD 1016–1:2017. In the contest, two reinforced...journal article 2021

Wiegel, M.F. (author), de Boer, W.P. (author), van Koningsveld, M. (author), van der Hout, A.J. (author), Reniers, A.J.H.M. (author)Seaport operability is key to the economic viability of ports. Metocean conditions (e.g., wind, short waves, and infragravity waves) affect this operability when certain thresholds are exceeded. This paper describes a method for the global mapping of seaport operability risk indicators using open-source metocean data. This global-scale...journal article 2021

(author)</p><p class="MsoNormal">Over glacial-interglacial cycles, the evolution of an ice sheet is influenced by Glacial isostatic adjustment (GIA) via two negative feedback loops. Firstly, vertical bedrock deformation due to a changing ice load alters ice-sheet surface elevation. For example, an increasing ice load leads to a lower bedrock...abstract 2020

Honig, Floris (author), Vermeulen, Steven (author), Zadpoor, A.A. (author), de Boer, Jan (author), Fratila-Apachitei, E.L. (author)The ability to control the interactions between functional biomaterials and biological systems is of great importance for tissue engineering and regenerative medicine. However, the underlying mechanisms defining the interplay between biomaterial properties and the human body are complex. Therefore, a key challenge is to design biomaterials that...review 2020

(author), van Zonneveld, A. J. (author)The durability of prosthetic arteriovenous (AV) grafts for hemodialysis access is low, predominantly due to stenotic lesions in the venous outflow tract and infectious complications. Tissue engineered blood vessels (TEBVs) might offer a tailor-made autologous alternative for prosthetic grafts. We have designed a method in which TEBVs are...journal article 2020

In a proof load test, a load representative of the factored live load is applied to the bridge at the critical position. If the bridge can carry this load without distress, the proof load test shows experimentally that the bridge fulfills the requirements of the...journal article 2019

Performance evaluation of wave input reduction techniques for modeling inter-annual sandbar dynamicsde Queiroz, Bruna (author), Scheel, F. (author), Caires, Sofia (author), Walstra, D.J.R. (author), Olij, Derrick (author), Yoo, Jeseon (author), Reniers, A.J.H.M. (author), de Boer, W.P. (author)In process-based numerical models, reducing the amount of input parameters, known as input reduction (IR), is often required to reduce the computational effort of these models and to enable long-term, ensemble predictions. Currently, a comprehensive performance assessment of IR-methods is lacking, which hampers guidance on selecting suitable...journal article 2019

(author), Pappalardo, Marta (author), Rovere, Alessio (author)Sea-level indicators dated to the Last Interglacial, or Marine Isotope Stage (MIS) 5e, have a twofold value. First, they can be used to constrain the melting of Greenland and Antarctic Ice Sheets in response to global warming scenarios. Second, they can be used to calculate the vertical crustal rates at active margins. For both applications,...journal article 2018
