Kulsum, U. (author), Timmermans, Jos (author), Haasnoot, Marjolijn (author), Shah Alam Khan, M. (author), Thissen, W.A.H. (author)To deal with large uncertainties about future climate and socio-economic developments, planners in deltas are adopting an integrative and adaptive planning approach referred to as Adaptive Delta Management (ADM). Bangladesh has used the ADM approach for the development of its adaptive plan; Bangladesh Delta Plan 2100 (BDP 2100). The success...journal article 2021

Daniilidis, Alexandros (author), Saeid, S. (author), Gholizadeh Doonechaly, N. (author)Geothermal energy is gaining momentum as a renewable energy source. Reservoir simulation studies are often used to understand the underlying physics interactions and support decision making. Uncertainty related to geothermal systems can be substantial for subsurface and operational parameters and their interaction with regards to the output...journal article 2021

De Jaeger, Ina (author), Lago, Jesus (author), Saelens, Dirk (author)To assess the impact of implementing energy efficiency and renewable energy measures, urban building energy models are emerging. In these models, due to the lack of data, the natural variability of the existing building stock is often highly underestimated and uncertainty on the simulated energy use arises. Therefore, this work proposes a...journal article 2021

Klenk, M.B.O.T. (author), van de Poel, I.R. (author)Pandemics like COVID-19 confront us with decisions about life and death that come with great uncertainty, factual as well as moral. How should policy makers deal with such uncertainty? We suggest that rather than to deliberate until they have found the right course of action, they better do moral experiments that generate relevant experiences...journal article 2021

Gravell, Benjamin (author), Mohajerin Esfahani, P. (author), Summers, Tyler H. (author)The linear quadratic regulator (LQR) problem has reemerged as an important theoretical benchmark for reinforcement learning-based control of complex dynamical systems with continuous state and action spaces. In contrast with nearly all recent work in this area, we consider multiplicative noise models, which are increasingly relevant because...journal article 2021

Liu, Di (author), Baldi, S. (author), Jain, V. (author), Yu, Wenwu (author), Frasca, Paolo (author)Recently proposed adaptive platooning strategies for connected automated vehicles are able to cope with uncertain vehicle parameters (uncertain driveline time constants), but can handle only acyclic graphs like look-ahead graphs. This prevents from enhancing platooning protocols with synchronized merging maneuvers, where cyclic communication...journal article 2021

Delimpaltadakis, Giannis (author), Mazo, M. (author)In this work, we derive a region-based self-triggered control (STC) scheme for nonlinear systems with bounded disturbances and model uncertainties. The proposed STC scheme is able to guarantee different performance specifications (e.g. stability, boundedness, etc.), depending on the event-triggered control (ETC) triggering function that is...journal article 2021

Zhu, Y. (author), Goverde, R.M.P. (author)Unexpected disruptions occur frequently in the railways, during which many train services cannot run as scheduled. This paper deals with timetable rescheduling during such disruptions, particularly in the case where all tracks between two stations are blocked for hours. In practice, a disruption may become shorter or longer than predicted. To...journal article 2020

Papachristos, George (author), van de Kaa, G. (author)Standards competition is a complicated process influenced by a large number of factors and mechanisms. This article develops a simulation model that draws on current theory of standards competition dynamics and represents the interplay of strategic factors that firms can use to gain a competitive advantage. The model is used to reproduce four...review 2020

Rostampour, Vahab (author), Ferrari, Riccardo M.G. (author), Teixeira, Andre M.H. (author), Keviczky, T. (author)In this article two limitations in current distributed model based approaches for anomaly detection in large-scale uncertain nonlinear systems are addressed. The first limitation regards the high conservativeness of deterministic detection thresholds, against which a novel family of set-based thresholds is proposed. Such set-based thresholds...journal article 2020

Sun, Sihao (author), Wang, Xuerui (author), Chu, Q. P. (author), de Visser, C.C. (author)In order to further expand the flight envelope of quadrotors under actuator failures, we design a nonlinear sensor-based fault-tolerant controller to stabilize a quadrotor with failure of two opposing rotors in the high-speed flight condition (>8 m/s). The incremental nonlinear dynamic inversion approach which excels in handling model...journal article 2020

Moallemi, Enayat A. (author), Kwakkel, J.H. (author), de Haan, Fjalar J. (author), Bryan, Brett A. (author)Modeling is a crucial approach for understanding the past and exploring the future of coupled human-natural systems. However, uncertainty in various forms challenges inferences from modeling results. Model-based support for decision-making has increasingly adopted an emerging exploratory approach. This approach addresses uncertainty...journal article 2020

Daniilidis, Alexandros (author), Nick, H.M. (author), Bruhn, D.F. (author)Interest in direct use geothermal systems is increasing due to their ability to supply renewable, environmentally friendly heat. Such systems are mostly developed in conduction dominated geological settings where faults are often encountered. Interdependencies between physical, design and operational parameters make it difficult to assess the...journal article 2020

van Dorsser, Cornelis (author), Taneja, P. (author), Walker, W.E. (author), Marchau, V.A.W.J. (author)Policymakers need to make policies for an uncertain future, and policy analysts assist policymakers in choosing preferred courses of action. Despite a longstanding recognition that the futures field can contribute a great deal to policy analysis, futures work is not used to its full potential as an element of policy analysis. This is partly due...journal article 2020

van Maren, D.S. (author), Vroom, J. (author), Fettweis, M. (author), Vanlede, J.D.S.M. (author)Despite availability of a large amount of observational data and modelling studies, the mechanisms maintaining the Turbidity Maximum in the Belgian-Dutch coastal zone around the port of Zeebrugge (Belgium) are insufficiently understood. In order to better understand the dynamics of this turbidity maximum we examine the role of baroclinic ...journal article 2020

Roy, S. (author), Baldi, S. (author), Fridman, Leonid M. (author)Adaptive Sliding Mode Control (ASMC) aims to adapt the switching gain in such a way to cope with possibly unknown uncertainty. In state-of-the-art ASMC methods, a priori boundedness of the uncertainty is crucial to ensure boundedness for the switching gain and uniformly ultimately boundedness. A priori bounded uncertainty might impose a...journal article 2020
