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

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

Roungas, V. (author), Meijer, Sebastiaan (author), Verbraeck, A. (author)Thirty years of research on validation and verification have returned a plethora of methods and statistical techniques through methodological and case studies. It is, however, this abundance of methods and techniques that poses a major challenge. Due to time and budget constraints, it is impossible to apply all the available methods and...journal article 2018

(author), Liu, M. (author), Woudstra, T. (author), Aravind, P.V. (author)This paper describes the steps involved in the design, construction, and testing of a gasifier-specific solid oxide fuel cell (SOFC) system. The design choices are based on reported thermodynamic simulation results for the entire gasifier- gas cleanup-SOFC system. The constructed SOFC system is tested and the measured parameters are compared...journal article 2018

(author)DNSSEC offers protection against spoofing of DNS data by providing origin authentication, ensuring data integrity and authentication of non-existence by using public-key cryptography. Although the relevance of securing a technology as crucial to the Internet as DNS is obvious, the DNSSEC implementation increases the complexity of the deployed...journal article 2015

Van der Kooij, K. (author), Hoogendoorn, E. (author), Spijkerman, R. (author), Visch, V.T. (author)The application of games for behavioral change has seen a surge in popularity but evidence on the efficacy of these games is contradictory. Anecdotal findings seem to confirm their motivational value whereas most quantitative findings from randomized controlled trials (RCT) are negative or difficult to interpret. One cause for the contradictory...journal article 2015

De Bruijn, E. (author), Van der Helm, F.C.T. (author), Happee, R. (author)Background: Musculoskeletal models served to analyze head–neck motion and injury during automotive impact. Although muscle activation is known to affect the kinematic response, a model with properly validated muscle contributions does not exist to date. The goal of this study was to enhance a musculoskeletal neck model and to validate passive...journal article 2015
