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

Duinkerken, Elwin (author)When trains are not actively traveling on the main rail network, they to be parked and prepared for their next journey. This is a complex problem, involving several interconnected subproblems. Additionally, there is uncertainty in this environment which can render initial plans infeasible during their execution. To ensure trains are able to...master thesis 2023

Gardos Reid, Reuben (author)Over 700 trains in the Netherlands are used daily for passenger transportation. Train operations involve tasks like parking, recombination, cleaning, and maintenance, which take place in shunting yards. The train unit shunting problem (TUSP) is a complex planning problem made more difficult by uncertainties such as delays. Most existing...master thesis 2023

Marrone, Camillo (author)This thesis investigates the robustness of multivariate S-estimators, which are statistical methods used to estimate the location and covariance parameters of multivariate distributions. Outliers, or atypical observations, can significantly impact statistical analyses, leading to incorrect conclusions. Robust methods, such as S-estimators, aim...bachelor thesis 2023

van Heel, Liesbeth (author), Pretelt, Manuela (author), Herweijer, Milee (author), van Oel, C.J. (author)The COVID-19 pandemic placed healthcare design at the heart of the crisis. Hospitals faced challenges such as increasing their ICU capacity and enabling physical-distancing measures to prevent infectious spread. They also needed to co-house suspected COVID patients and nonCOVID patients with different requirements and enforce separate entrances...journal article 2023

van der Pluijm, Ricardo (author)The Flying V is an innovative new aircraft concept currently being developed by the faculty of Aerospace Engineering at Delft University of Technology. This aircraft is a flying wing having a large sweep on the inner section, and a small sweep angle at the outer, giving the aircraft its characteristic V shape. The objective of this research is...master thesis 2021

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

Danks, Brigitte (author)The aim of this thesis was to objectively and quantitatively assess the accuracy and robustness of two-dimensional sequentially linear analysis (SLA) in comparison to nonlinear finite element analysis (NLFEA), for a range of experiments of reinforced concrete structures with proportional and non-proportional loading schemes. Non-proportional...master thesis 2019

van den Broek, Maarten (author)Bipedal running gaits may be self-stable if they rely on the intrinsic system dynamics to attenuate deviations. This use of passive dynamics for gait stability has been observed in biological running and applied for running robotics, supported with the results of numerical simulations. It is an important aspect of the development of fast and...master thesis 2019

Huijzer, Leonard (author)The Wanda software package developed by Deltares can used for simulating both steady state and transient fluid flow in pipeline systems. Steady state simulations are used for initial system design and transient flow simulations are used for doing water hammer analysis in pipeline systems. For both types of simulations a system consisting of both...master thesis 2018

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
