van Heel, M.E. (author), Pretelt, Manuela (author), van Gelder, M.H. (author), van Oel, C.J. (author)Background: The COVID-19 pandemic placed healthcare design at the heart of the crisis. Hospitals faced challenges such as rapidly increasing their intensive care unit capacity, enabling physical distancing measures, quickly converting to telehealth and telework practices, and above all, keeping patients and staff safe. Improving flexibility...journal article 2024

Tajdari, F. (author), Toulkani, Naeim Ebrahimi (author)Aiming at operating optimally minimizing error of tracking and designing control effort, this study presents a novel generalizable methodology of an optimal torque control for a 6-degree-of-freedom Stewart platform with rotary actuators. In the proposed approach, a linear quadratic integral regulator with the least sensitivity to controller...journal article 2021

Chakraborty, S.S. (author)Robustness of a concurrent program ensures that its behaviors on a weak concurrency model are indistinguishable from those on a stronger model. Enforcing robustness is particularly useful when porting or migrating applications between architectures. Existing tools mostly focus on ensuring sequential consistency (SC) robustness which is a...conference paper 2021

Vert, M.P.J. (author), Sharpanskykh, Alexei (author), Curran, R. (author)Resilience is commonly understood as the capacity for a system to maintain a desirable state while undergoing adversity or to return to a desirable state as quickly as possible after being impacted. In this paper, we focus on resilience for complex sociotechnical systems (STS), specifically those where safety is an important aspect. Two main...journal article 2021

Coppola, M. (author), McGuire, K.N. (author), de Wagter, C. (author), de Croon, G.C.H.E. (author)This work presents a review and discussion of the challenges that must be solved in order to successfully develop swarms of Micro Air Vehicles (MAVs) for real world operations. From the discussion, we extract constraints and links that relate the local level MAV capabilities to the global operations of the swarm. These should be taken into...review 2020

McPhail, C. (author), Maier, H. R. (author), Westra, S. (author), Kwakkel, J.H. (author), van der Linden, L. (author)Multiple plausible future scenarios are being used increasingly in preference to a single deterministic or probabilistic prediction of the future in the long-term planning of water resources systems. These scenarios enable the determination of the robustness of a system—the consideration of performance across a range of plausible futures—and...journal article 2020

Corman, Francesco (author), Quaglietta, E. (author), Goverde, R.M.P. (author)Railway transportation provides sustainable, fast and safe transport. Its attractiveness is linked to a broad concept of service reliability: the capability to adhere to a timetable in the presence of delays perturbing traffic. To counter these phenomena, real-time rescheduling can be used, changing train orders and times, according to rules of...journal article 2018

Klijn, F. (author), Asselman, Nathalie (author), Wagenaar, Dennis (author)The Netherlands has just finished implementing the Room for the Rivers program along the Rhine and Meuse Rivers in response to increasing river discharges. Recently, making more room for the river is, however, being challenged for future application because the flood defenses are assessed to be too weak and will need reinforcement anyway. To be...journal article 2018

Klijn, F. (author), Asselman, Nathalie (author), Mosselman, E. (author)There is increasing attention for the robustness of systems, in view of more frequent and more extreme weather events. Calls to increase a system's robustness are usually motivated by the resulting reduced sensitivity to extreme events and uncertainties about their probability of occurrence. The concept has been elaborated for flood risk systems...journal article 2018

Hernández, Carlos (author), Bermejo-Alonso, Julita (author), Sanz, Ricardo (author)Robot control software endows robots with advanced capabilities for autonomous operation, such as navigation, object recognition or manipulation, in unstructured and dynamic environments. However, there is a steady need for more robust operation, where robots should perform complex tasks by reliably exploiting these novel capabilities. Mission...journal article 2018

van Schaijk, Oscar R.P. (author), Visser, H.G. (author)In this paper we present a novel method to improve the robustness of solutions to the Flight-to-Gate Assignment Problem (FGAP), with the aim to reduce the need for gate re-planning due to unpredicted flight schedule disturbances in the daily operations at an airport. We propose an approach in which the deterministic gate constraints are...journal article 2017

Calvert, S.C. (author), Snelder, M. (author)Major and minor disturbances can have a considerable impact on the performance of road networks. In this respect, resilience is considered as the ability of a road section to resist and to recover from disturbances in traffic flow. In this contribution, an indicator is presented, the Link Performance Index for Resilience (LPIR), which evaluates...journal article 2017

Pinto, J. (author), Klomp, R.E. (author), Borst, C. (author), Van Paassen, M.M. (author), Mulder, M. (author)The concept of trajectory-based operations as proposed by SESAR and NextGen seeks to increase airspace efficiency and capacity by introducing time as an explicit control variable. Such form of operations lean heavily on the introduction of higher levels of automation to support the human air traffic controller in performing this new task. In...conference paper 2015
