den Ouden, Ronan (author)Random walks have been used in a number of different fields for a long time. With the rise of of quantum random walks a lot of these applications have been made more efficient. Recently there have been a lot of improvements in the realization of these quantum random walks in real world systems. <br/>In this research, the effect of uncertainty in...bachelor thesis 2023

Meyer, Han (author)We need to tell a new story about urbanizing delta regions. Historically, large-scale ‘iconic’ hydraulic works and modern industrial ports have been celebrated as showing the power of humans to control and subject nature. The emphasis on this part of cultural heritage tends to bury the remains of engineering and urban development of the previous...book chapter 2020

Biljecki, F. (author), Ledoux, H. (author), Stoter, J. (author)This paper describes the analysis of the propagation of positional uncertainty in 3D city models to the uncertainty in the computation of their volumes. Current work related to error propagation in GIS is limited to 2D data and 2D GIS operations, especially of rasters. In this research we have (1) developed two engines, one that generates random...conference paper 2014

Schnejdar, Sebastian (author), Heinrich, Michael (author), Sebastian, Steffen (author), Woltering, Rene-Ojas (author)The German open-ended real estate fund industry was strongly hit by massive out flows in the course of the global financial crisis. In total, 18 public and institutional real estate funds had to stop the redemption of shares and were ultimately forced to liquidate their portfolios. Investors of these funds either have to await the stepwise...conference paper 2017

Brocal, Francisco (author), González-Gaya, G. (author), Sebastián, Miguel A. (author), Reniers, G.L.L.M.E. (author), Paltrinieri, Nicola (author)As a result of the important and rapid technological advances in industrial processes, in recent years the scientific interest in the field of occupational health and safety (OH&S) is increasing. This scenario of continuous change generates both new opportunities and new challenges in the workplace. This circumstance allows eliminating or...conference paper 2019

Tran, N.B. (author), Van Der Kwast, Johannes (author), Mul, Marloes (author), Seyoum, S.D. (author), Uijlenhoet, R. (author), Jewitt, G.P.W. (author)Evapotranspiration (ET), a key variable in both water and energy cycles. It is very challenging to measure or estimate in large regions. Among many approaches to estimate ET indirectly (e.g. through hydrological modelling), models that are based on satellite remote sensing data (RS) are increasingly being used. However, the RS-based models...conference paper 2022

Irnich, Jakob (author), van der Wal, C.N. (author), Duives, D.C. (author), Auping, Willem L. (author)Different leader-follower behaviors may be observed in models, such as group gathering, backtracking, and changing between groups. However, a comparison of these behaviors resulting in possible substantially different estimates of optimal evacuation procedures is lacking. Hence, we developed an agent-based model in combination with exploratory...conference paper 2023

Aydin, N.Y. (author), Krishnan, S. (author), Yu, H. (author), Comes, M. (author)Cities are complex socio-technical systems (STSs) under tremendous stress due to climate change. To incorporate resilience into urban plans and move towards evidence-based long-term decision-making, we must unravel complex land-use dynamics and the effect of climate uncertainties on cities. Currently, land-use dynamics are explored through...conference paper 2022

Schwarting, Wilko (author), Alonso-Mora, J. (author), Pauli, Liam (author), Karaman, Sertac (author), Rus, Daniela (author)Current state-of-the-art vehicle safety systems, such as assistive braking or automatic lane following, are still only able to help in relatively simple driving situations. We introduce a Parallel Autonomy shared-control framework that produces safe trajectories based on human inputs even in much more complex driving scenarios, such as those...conference paper 2017

Current methods for information gathering, such as Monte Carlo Tree Search, are capable of reasoning over long horizons, but they are computationally expensive. An alternative...conference paper 2022

Abrishami, S. (author), Khakzad, N. (author), van Gelder, P.H.A.J.M. (author), Hosseini, Seyed Mahmoud (author)Success Likelihood Index Model (SLIM) is one of the widely-used methods in human reliability assessment especially when data is insufficient. However, this method suffers from uncertainty as it heavily relies on expert judgment for determining the model parameters such as the rates and weights of the performance shaping factors. The present...conference paper 2019

Philipsen, R.M. (author), de Weerdt, M.M. (author), De Vries, Laurens (author)Large controllable loads, such as electric vehicles, are increasingly penetrating electricity distribution feeders. To avoid local congestion, their consumption behaviour must be steered, for which a real-time price propagated down from the transmission system does not suffice, as it does not reflect local grid conditions. To efficiently steer...conference paper 2016

(author)Model predictions of biogeochemical fluxes on the landscape scale are highly uncertain, both with respect to stochastic (parameter) and structural uncertainty. The idea of our ensemble modelling approach is to reduce the predictive uncertainty by covering part of the parameter and model structural uncertainty. In this study 4 different models...conference paper 2009

Zwaginga, J.J. (author), Pruyn, J.F.J. (author)The maritime energy transition presents deep uncertainties that are difficult to deal with in the current ship design process. Even though other fields have stressed using adaptive strategies and explorative methods to deal with deep uncertainty, it is rarely included in ship design. Therefore, this paper compares three applicable methods to...conference paper 2022
