Kwakkel, J.H. (author)There is a growing interest in model-based decision support under deep uncertainty, reflected in a variety of approaches being put forward in the literature. A key idea shared among these is the use of models for exploratory rather than predictive purposes. Exploratory modeling aims at exploring the implications for decision making of the...journal article 2017

Duivenvoorden, Jorien R. (author), Käyhkö, Anna (author), Kwakkel, Erik (author), Dik, J. (author)This experiment demonstrates the large potential of macro-XRF imaging for the visualization of fragments of medieval manuscripts hidden in early-modern bookbindings. The invention of the printing press in the fifteenth century made manuscripts obsolete and bookbinders started recycling their strong parchment leaves to reinforce bindings of...journal article 2017

(author)Background: Cortical damage after stroke can drastically impair sensory and motor function of the upper limb, affecting the execution of activities of daily living and quality of life. Motor impairment after stroke has been thoroughly studied, however sensory impairment and its relation to movement control has received less attention. Integrity...journal article 2017

Filatova, O.G. (author), van Vliet, L.J. (author), Schouten, A.C. (author), Kwakkel, Gert (author), van der Helm, F.C.T. (author), Vos, F.M. (author)Better insight into white matter (WM) alterations after stroke onset could help to understand the underlying recovery mechanisms and improve future interventions. MR diffusion imaging enables to assess such changes. Our goal was to investigate the relation of WM diffusion characteristics derived from diffusion models of increasing complexity...journal article 2018

Eker, S. (author), Kwakkel, J.H. (author)Many-Objective Robust Decision Making (MORDM) is a prominent model-based approach for dealing with deep uncertainty. MORDM has four phases: a systems analytical problem formulation, a search phase to generate candidate solutions, a trade-off analysis where different strategies are compared across many objectives, and a scenario discovery...journal article 2018

Jaxa-Rozen, M. (author), Kwakkel, J.H. (author)Complex environmental models typically require global sensitivity analysis (GSA) to account for non-linearities and parametric interactions. However, variance-based GSA is highly computationally expensive. While different screening methods can estimate GSA results, these techniques typically impose restrictions on sampling methods and input...journal article 2018

Tegeltija, Miroslava (author), Oehmen, Josef (author), Kozin, Igor (author), Kwakkel, J.H. (author)Uncertainty assessment and management, as well as the associated decision making are increasingly important in a variety of scientific fields. While uncertainty analysis has a long tradition, meeting sustainable development goals through long-term Life Cycle Engineering (LCE) decision making demands addressing Deep Uncertainty (DU). DU...journal article 2018

van Berchum, E.C. (author), Mobley, William (author), Jonkman, Sebastiaan N. (author), Timmermans, Jos (author), Kwakkel, J.H. (author), Brody, Samuel D. (author)Large, complex coastal regions often require a combination of interventions to lower the risk of flooding to an acceptable level. In practice, a limited number of strategies are considered and interdependencies between interventions are often simplified. This paper presents the Multiple Lines of Defence Optimization System (MODOS)‐model. This...journal article 2018

(author)In hemiparetic stroke, functional recovery of paretic limb may occur with the reorganization of neural networks in the brain. Neuroimaging techniques, such as magnetic resonance imaging (MRI), have a high spatial resolution which can be used to reveal anatomical changes in the brain following a stroke. However, low temporal resolution of MRI...journal article 2018

Jaxa-Rozen, M. (author), Kwakkel, J.H. (author)Methods for testing and analyzing agent-based models have drawn increasing attention in the literature, in the context of efforts to establish standard frameworks for the development and documentation of models. This process can benefit from the use of established software environments for data analysis and visualization. For instance, the...journal article 2018

McPhail, C. (author), Maier, H. R. (author), Kwakkel, J.H. (author), Giuliani, M (author), Castelletti, A (author), Westra, S. (author)Robustness is being used increasingly for decision analysis in relation to deep uncertainty and many metrics have been proposed for its quantification. Recent studies have shown that the application of different robustness metrics can result in different rankings of decision alternatives, but there has been little discussion of what potential...journal article 2018

Jafino, B.A. (author), Kwakkel, J.H. (author), Haasnoot, M. (author)Integrated assessment models often treat land-use change as an external driving force. In reality, land-use is influenced by environmental conditions. This paper explores the merits of endogenising land-use change, i.e. making land-use change an internal dynamic process in models used for supporting climate adaptation planning. For this purpose,...journal article 2019

Raso, L. (author), Kwakkel, J.H. (author), Timmermans, Jos (author), Panthou, Geremy (author)Adaptive policies have emerged as a valuable strategy for dealing with uncertainties by recognising the capacity of systems to adapt over time to new circumstances and surprises. The efficacy of adaptive policies hinges on detecting on-going change and ensuring that actions are indeed taken if and when necessary. This is operationalised by...journal article 2019

(author), Bloemendal, Martin (author)The modelling of social-ecological systems can provide useful insights into the interaction of social and environmental processes. However, quantitative social-ecological models should acknowledge the complexity and uncertainty of both underlying subsystems. For example, the agent-based models which are increasingly popular for groundwater...journal article 2019

Ciullo, A. (author), De Bruijn, Karin M. (author), Kwakkel, J.H. (author), Klijn, F. (author)Rivers typically flow through multiple flood-protected areas which are clearly interconnected, as risk reduction measures taken at one area, e.g. heightening dikes or building flood storage areas, affect risk elsewhere. We call these interconnections 'hydraulic interactions'. The current approach to flood risk management, however, neglects...journal article 2019

Ciullo, A. (author), de Bruijn, Karin M. (author), Kwakkel, J.H. (author), Klijn, F. (author)Most alluvial plains in the world are protected by flood defences, for example, embankments, whose primary aim is to reduce the probability of flooding of the protected areas. At the same time, however, the presence of embankments at one area influences hydraulic conditions of downstream areas located on the same river. These hydraulic...journal article 2019
