Leffler, David (author), Burghout, Wilco (author), Cats, O. (author), Jenelius, Erik (author)This paper presents a comparative analysis of demand-responsive and fixed-schedule, fixed route operations for a simplified station-based feeder to mass transit scenario. Traffic dynamics, demand-responsive fleet coordination, and the behaviour of individual transit users are represented using a public transit simulation framework. Each...journal article 2020

(author), Mulder, Max (author)Objective: We tested whether a procedure in a hexapod simulator can cause incorrect assumptions of the bank angle (i.e., the “leans”) in airline pilots as well as incorrect interpretations of the attitude indicator (AI). Background: The effect of the leans on interpretation errors has previously been demonstrated in nonpilots. In-flight,...journal article 2020

Bal, Frans (author), Vleugel, J (author)In a world where the population and many economies are expanding rapidly the demand for freight transport keeps rising accordingly. As more goods are transported by a growing number of freight vehicles, in particular trucks and sea vessels, their already considerable negative environmental impact also rises. Technology advances, but demand...journal article 2020

Stroeven, P. (author), Li, Kai (author)Permeability estimates obtained by physical experiments and by simulations differ quite significantly. When biases at the experimental side would be eliminated, the expected modest gap could be bridged by surface layer modifications of the hardened cement paste, discussed herein. This involves the formation of a fractal-like nano-particle...journal article 2020

Vleugel, J (author), Bal, Frans (author)Modern societies rely on mass mobility, in particular by private car. Car numbers are growing worldwide due to economic and other factors. Nearly, all have engines that run on fossil fuels. Use of fossil fuels contributes to climate change (via CO <sub>2</sub>-emissions) and local air pollution (primary NO <sub>x</sub>- and PM <sub>10</sub>...journal article 2019

Heraganahally, Subash (author), Mehra, Sumit (author), Veitch, D.E. (author), Sajkov, Dimitar (author), Falhammar, Henrik (author), Morton, Sharon (author)Purpose of the study: Pleural diseases are common in clinical practice. Doctors in training often encounter these patients and are expected to perform diagnostic and therapeutic pleural procedures with confidence and safely. However, pleural procedures can be associated with significant complications, especially when performed by less...journal article 2019

Grottoli, M. (author), Cleij, D. (author), Pretto, Paolo (author), Lemmens, Yves (author), Happee, R. (author), Bülthoff, Heinrich H. (author)Optimization-based motion cueing algorithms based on model predictive control have been recently implemented to reproduce the motion of a car within the limited workspace of a driving simulator. These algorithms require a reference of the future vehicle motion to compute a prediction of the system response. Assumptions regarding the future...journal article 2019

López, Claudio (author), Cvetkovic, M. (author), Palensky, P. (author)Co-simulation has become increasingly popular as a tool for dealing with the unprecedented complexity of modern engineering systems, such as electrical power systems and the AC circuits that compose them. Co-simulation is useful when migrating the models of each subsystem to a single monolithic simulator is either impractical or impossible,...journal article 2019

Santos, Gonçalo Gonçalves Duarte (author), Correia, Gonçalo (author)This paper proposes a real-time decision support tool based on the rolling-horizon principle that manages staff activities (relocations and maintenance) of a one-way carsharing system and considers carpooling the staff in the relocated carsharing vehicles for extra cost reduction. The decision support tool is composed of three elements: a...journal article 2019

Vleugel, J (author), Bal, Frans (author)Tourism is a fast-growing key industry, which provides an economic rationale for governments to stimulate it. The more it grows, the higher the negative environmental effects and the more the use of space, resources, pollution and travel. Sustainable tourism aims to strike a balance between the environmental, economic and social effects of...journal article 2019

Santbergen, R. (author), Uzu, Hisashi (author), Yamamoto, Kenji (author), Zeman, M. (author)We use simulations to optimize perovskite/silicon tandem solar cells in a novel three-terminal configuration, with one terminal at the front and two at the rear. We consider configurations in which the top cell has either the inverted or the same polarity as the bottom cell. Our goal is to minimize the optical losses, to compare the...journal article 2019

Yang, M. (author), López-Dekker, Paco (author), Dheenathayalan, P. (author), Biljecki, Filip (author), Liao, Mingsheng (author), Hanssen, R.F. (author)Persistent scatterers (PSs) are coherent measurement points obtained from time series of satellite radar images, which are used to detect and estimate millimeter-scale displacements of the terrain or man-made structures. However, associating these measurement points with specific physical objects is not straightforward, which hampers the...journal article 2019

Cleij, D. (author), Venrooij, J. (author), Pretto, Paolo (author), Pool, D.M. (author), Mulder, Max (author), Bulthoff, Heinrich H. (author)Motion cueing algorithms are used in motion simulation to map the inertial vehicle motion onto the limited simulator motion space. This mapping causes mismatches between the unrestricted visual motion and the constrained inertial motion, which results in perceived motion incongruence (PMI). It is still largely unknown what exactly causes...journal article 2018

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), Nguyen, V. H. (author)A driving force for the realization of a sustainable energy supply in Europe is the integration of distributed, renewable energy resources. Due to their dynamic and stochastic generation behaviour, utilities and network operators are confronted with a more complex operation of the underlying distribution grids. Additionally, due to the higher...journal article 2018
