Connolly, Ronan (author)Ice accumulation on aircraft surfaces is a prevalent issue, and icephobic coating strategies can be implemented to assist in the removal of or ice on an aircraft. However little is known regarding the effects of novel icephobic coatings and surfaces on ice adhesion strength, which is difficult to measure and quantify, and is typically reported...master thesis 2024

Li, Fengxiang (author), Fitrianie, S. (author), Bruijnes, M. (author), Abdulrahman, A. (author), Guo, Fu (author), Brinkman, W.P. (author)In the published article, there was an error in Table 5. For each second construct/dimension, the means are swapped between Chinese and English data, which is caused by an error in the underlying R script. Consequently, the plus and minus signs for the delta and CI values are also wrong. The corrected Table 5 and its caption appear below....journal article 2024

Hobeika, N. (author), Garcia Sanchez, C. (author), Bluyssen, P.M. (author)The corona pandemic accelerated a lot of studies about aerosol dispersion and different aerosol-generating tasks ranging in intensity from sneezing to breathing. Both measurements and numerical simulations were used to understand the behaviour of aerosols. For numerical simulations, Computational Fluid Dynamic (CFD) simulations were used;...conference paper 2023

Grottoli, M. (author), Mulder, Max (author), Happee, R. (author)The use of driving simulators for training and for development of new vehicles is widely spread in the automotive industry. In the last decade, a few motorcycle riding simulators have been developed for similar purposes, with focus on maneuvering at high speed. This article presents the subjective and objective evaluation of a motorcycle...journal article 2022

Lovato, S. (author), Toxopeus, S.L. (author), Settels, J.W. (author), Keetels, G.H. (author)The ship’s resistance and manoeuvrability in shallow waters can be adversely influenced by the presence of fluid mud layers on the seabed of ports and waterways. Fluid mud exhibits a complex non-Newtonian rheology that is often described using the Herschel–Bulkley model. The latter has been recently implemented in a maritime finite-volume CFD...journal article 2022

(author), Ramesh Reddy, L. (author)Currently, the design of floating offshore wind systems is primarily based on mid-fidelity models with empirical drag forces. The tuning of the model coefficients requires data from either experiments or high-fidelity simulations. As part of the OC6 (Offshore Code Comparison Collaboration, Continued, with Correlation, and unCertainty (OC6) is a...journal article 2022

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

Kniestedt, I. (author), Gómez Maureira, Marcello A. (author), Lefter, I. (author), Lukosch, Stephan (author), Brazier, F.M. (author)Validation of serious games tends to focus on evaluating their design as a whole. While this helps to assess whether a particular combination of game mechanics is successful, it provides little insight into how individual mechanics contribute or detract from a serious game's purpose or a player's game experience. This study analyses the effect...journal article 2021

(author)We present the VECMA toolkit (VECMAtk), a flexible software environment for single and multiscale simulations that introduces directly applicable and reusable procedures for verification, validation (V&V), sensitivity analysis (SA) and uncertainty quantication (UQ). It enables users to verify key aspects of their applications,...journal article 2021

Roungas, V. (author), Bekius, F.A. (author), Verbraeck, A. (author), Meijer, S.A. (author)Gaming simulations (games) for policy and decision making have been the neglected “sibling” of educational and training games. The latter have experienced a widespread usage by practitioners and researchers, while the former have had limited, yet slowly increasing, adoption by organisations. As a result, various issues developing and using these...journal article 2020

(author), Pretto, Paolo (author), Islam, Hassaan (author), Stettinger, Georg (author), Horn, Martin (author)Closed-loop validation of autonomous vehicles is an open problem, significantly influencing development and adoption of this technology. The main contribution of this paper is a novel approach to reproducible, scenario-based validation that decouples the problem into several sub-problems, while avoiding to brake the crucial couplings. First,...conference paper 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

Akporotu, Richard (author)<br/>This research has shed light on the capability of the HASP model in reproducing the dilatant behaviour of OC clays in drained and undrained conditions. The model is formulated by employing a combined hardening rule and uses the void ratio as a state variable while maintaining the simplicity of the MCC model. However, a sensitivity analysis...master thesis 2019

Hulsbergen, Bas (author)Shipyards these days see an increase in customers that specify combined speed and seakeeping ability design requirements. This requires the shipyard to make a prediction of the additional installed power required to maintain a certain speed when waves are encountered. The additional required installed power is directly related to the average...master thesis 2019

Geertsma, R.D. (author)Shipping plays a crucial role in modern society, but has to reduce its impact on the environment. The commercial availability of power electronic converters and lithium-ion batteries provides an opportunity to improve performance of ships energy systems while reducing their environmental impact.

Breedeveld, J. (author), Zwanenburg, C. (author), Van, M. (author), Lengkeek, H.J. (author)Levees in the Netherlands have traditionally been constructed from soil. Climate change and land subsidence require heightening and/or reinforcing these existing levees. Traditional reinforcements demand additional space, which in some cases conflicts with existing buildings. Applying sheet pile walls in levees allows for strengthening while...conference paper 2019
