Klerks, Joosje (author)In common practice, quay walls are engineered to fulfil their services for a minimum lifetime. However, in many cases, quay walls are designed stronger than minimally required, which means that the quay wall could be able to serve its purpose over a longer period or endure higher loads. In general, the optimization of quay wall designs or the...master thesis 2024

Bechan, Rushil (author)The abstract outlines a study focusing on improving the design approach for flexible dolphins, vital marine structures used for vessel berthing and mooring. Current design methodologies, particularly those outlined in the CROW C1005 handbook (2018), are questioned due to potential conservatism stemming from insufficiently calibrated partial...master thesis 2024

Katona, Misha (author)Through several contractions, stiff competition, and increasing passenger expectations, airports must evolve continually. One of the main avenues for this has been improving the efficiency of the security check- points, which are airports’ primary bottlenecks. Operational optimisation methods, such as resource and task scheduling are relatively...master thesis 2024

Hemel, M. (author), Peters, D.J. (author), Schweckendiek, T. (author), Jonkman, Sebastiaan N. (author)The historic canal walls of Amsterdam, stretching 200 km in total, are constructed as a masonry wall on a timber deck supported by vertical timber piles. Understanding the resistance against lateral failure of these quays has been challenging due to uncertainties in their working principles, geometry, soil and structural properties. This...journal article 2024

Tavares, Sérgio M.O. (author), Ribeiro, João A. (author), Alves Ribeiro, B.M. (author), de Castro, Paulo M.S.T. (author)Numerical modeling tools are essential in aircraft structural design, yet they face challenges in accurately reflecting real-world behavior due to factors like material properties scatter and manufacturing-induced deviations. This article addresses the potential impact of digital twins on overcoming these limitations and enhancing model...journal article 2024

Hemel, M. (author)Amsterdam faces the challenge of maintaining a domain of 200 km historic quay walls, which is a vital part of the city’s historical landscape. Many quays are currently in poor condition and require renovation or replacement in the near future, significantly impacting the city. The quay walls can be up to 300 years old and their structure...doctoral thesis 2023

(author), Koks, Elco (author), van Ginkel, Kees (author)The floods in the Netherlands in the summer of 2021 led to severe economic damage and losses in the affected area. A first estimate in September 2021 showed that more than 2,500 houses, more than 5,000 inhabitants and around 600 businesses were affected. Using the Dutch standard Flood Damage and Loss Model (SSM2017), and based on figures from...journal article 2023

Igea, Felipe (author), Cicirello, A. (author)Multi-modal distributions of some physics-based model parameters are often encountered in engineering due to different situations such as a change in some environmental conditions, and the presence of some types of damage and non-linearity. In statistical model updating, for locally identifiable parameters, it can be anticipated that multi...journal article 2023

Feng, Cheng (author), Zheng, Kedi (author), Zhou, Yangze (author), Palensky, P. (author), Chen, Qixin (author)With the proliferation of distributed energy resources (DERs), electricity consumers in virtual power plants (VPPs) are transitioning into prosumers and are encouraged to share surplus energy with peers. Nevertheless, large-scale energy sharing among thousands of prosumers may encounter communication-related challenges. Communication network...journal article 2023

Yuan, S. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author)An integrated approach for performance assessment and management of safety barriers in a systemic manner is needed concerning the prevention and mitigation of major accidents in chemical process industries. Particularly, the effects of safety barriers on system risk reduction should be assessed in a dynamic manner to support the decision-making...journal article 2023

Ortner, Thomas (author), Pes, Lorenzo (author), Gentinetta, Joris (author), Frenkel, C. (author), Pantazi, Angeliki (author)Recurrent neural networks trained with the backpropagation through time (BPTT) algorithm have led to astounding successes in various temporal tasks. However, BPTT introduces severe limitations, such as the requirement to propagate information backwards through time, the weight symmetry requirement, as well as update-locking in space and time....conference paper 2023

Zheng, X. (author), Yang, Feng (author), Shiau, Jim (author), Lai, F. (author), Dias, Daniel (author)This paper presents a stability study on the collapse mechanisms of a plane-strain tunnel face in c-ϕ soils using the upper bound finite element method with rigid translatory moving elements (UBFELA-RTME) and nonlinear programming technique. Practical considerations are given to the unlined length influence behind the tunnel face. An advanced...journal article 2023

de Vries, R. (author), Lantsoght, E.O.L. (author), Steenbergen, Raphaël D.J.M. (author), Fennis, Sonja A.A.M. (author)In the evaluation of existing bridges and viaducts, relying solely on a desk study is often inadequate for determining their structural reliability. Performing a proof load test provides valuable field data that offers detailed information about the structural integrity. However, the relation between the magnitude of the load and the...journal article 2023

Effenberger, Moritz (author)This research focuses on reliability-based, Bayesian updating of grout anchors’ bearing capacity. Firstly, grouted anchors are commonly used in practice, even though large uncertainties surround their bearing capacity. Secondly, every anchor must be tested on their working load for quality assurance. Because of the combination of those two...master thesis 2022

Reddel, Felicitas (author)Misinformation on social media is an urgent grand challenge. Misinformation has caused excess deaths because people abstain from getting vaccinated and other evidence-based prevention behaviors. Misinformation also influences various other important topics such as climate change. And it has the potential to influence countless other areas. In...master thesis 2022

Rikkert, S.J.H. (author)A major part of the Netherlands is prone to flooding: roughly 60%. Therefore, a large system of flood defences protects the country from flooding. These flood defences are divided into primary and regional flood defence systems. Primary flood defences protect areas against catastrophical flooding events from the sea, big lakes and major rivers,...doctoral thesis 2022

van der Krogt, M.G. (author)Dikes are crucial for the protection against floods. One of the ways in which dikes can fail is by the instability of the inner slope. Credible probabilities of failure for slope stability are essential for the safety assessment of existing dikes and the design of dike reinforcements. This dissertation focuses on improving failure probability...doctoral thesis 2022
