Mulder, W.A. (author)The representation of a force or moment point source in a spectral finite-element code for modelling elastic wave propagation becomes fundamentally different in degenerate cases where the source is located on the boundary of an element. This difference is related to the fact that the finite-element basis functions are continuous across...journal article 2020

Kirkwood, N.R.M. (author), De Backer, Annick (author), Longo, Alessandro (author), Geuchies, J.J. (author), Mulder, J.T. (author), Renaud, N. (author), Bals, Sara (author), Manna, L. (author), Houtepen, A.J. (author)Zinc is routinely employed in the synthesis of InP quantum dots (QDs) to improve the photoluminescence efficiency and carrier mobility of the resulting In(Zn)P alloy nanostructures. The exact location of Zn in the final structures and the mechanism by which it enhances the optoelectronic properties of the QDs are debated. We use synchrotron X...journal article 2020

Van Riessen, Bart (author), Mulder, Judith (author), Negenborn, R.R. (author), Dekker, Rommert (author)The cargo fare class mix (CFCM) problem aims to find the optimal fare class mix for a given intermodal transportation network based on known client demands. It is based on a revenue management problem for aviation passengers, the fare class mix problem, but considering intermodal cargo transportation, two major differences apply. Firstly, the...journal article 2020

Reyes, María Elena L. (author), Zwagers, W.A. (author), Mulder, I. (author)Sustainable innovation and transitions are increasingly gaining traction within academia, industries, and policymakers. Despite the research efforts, sustaining innovation and operationalizing transitions still remains a barely explored field. The pragmatic step from understanding towards doing is often not made explicit in the literature. In...journal article 2020

Huisman, C.J. (author), Mulder, Clara H. (author)Given that insecure leases impact negatively on ontological security and subjective well-being, and given increasing pressure on European housing markets, more insight into insecure leases is timely. In this article, we assess the occurrence of temporary leases in the city of Amsterdam in 2015, and explore the characteristics of the tenants....journal article 2020

Borst, C. (author), Visser, Roeland M. (author), van Paassen, M.M. (author), Mulder, Max (author)In many work domains, the push toward higher levels of automation raises the concern of diminishing human expertise. Ecological interfaces could help operators in retaining and potentially even in acquiring expertise as they are hypothesized to lead to a deeper understanding of the work domain. This study explores the short-term impact of...journal article 2019

(author)Microemulsion systems consisting of D<sub>2</sub>O, an alkane, an anionic internal olefin sulfonate surfactant, salt and secondary butyl alcohol (SBA) as co-solvent are studied in a systematic way. In four different sample sets, either the salt content, SBA content or alkane carbon number was varied in order to study the effects of the...journal article 2019

Armanini, S.F. (author), Caetano, J. V. (author), de Visser, C.C. (author), Pavel, M.D. (author), de Croon, G.C.H.E. (author), Mulder, Max (author)Despite significant interest in tailless flapping-wing micro aerial vehicle designs, tailed configurations are often favoured, as they offer many benefits, such as static stability and a simpler control strategy, separating wing and tail control. However, the tail aerodynamics are highly complex due to the interaction between the unsteady...journal article 2019

van der El, Kasper (author), Pool, D.M. (author), Mulder, Max (author)Drivers rely on a variety of cues from different modalities while steering, but which exact cues are most important and how these different cues are used is still mostly unclear. The goal of our research project is to increase understanding of driver steering behavior; through a measuring and modeling approach we aim to extend the validity of...journal article 2019

van Leeuwen, T. D. (author), Cleij, D. (author), Pool, D.M. (author), Mulder, Max (author), Bülthoff, H. H. (author)In motion simulation, motion input scaling is often applied to deal with the limited motion envelopes of motion simulators. In this research, the time-varying effects of scaling the lateral specific force up or down during passive curve driving in a car driving simulation are investigated through a simulator experiment. It is concluded that...journal article 2019

Werthmüller, D. (author), Mulder, W.A. (author), Slob, E.C. (author)Controlled-source electromagnetic (CSEM) surveys are a common geophysical investigationtool in the search for, amongst other, groundwater, hydrocarbons, and minerals. The nu-merical modelling of CSEM data requires the solution of the Maxwell equations. These canbe simplified in the particular case of CSEM, as the frequencies used in surveys are...journal article 2019

Mulder, I. (author), Jaśkiewicz, T.J. (author), Morelli, Nicola (author)Along with the urgent need to reinvent our society, a series of paradigm shifts are already shaping transitions toward a more participatory and digital society. The current work takes stock of the promise of open data as a new resource and elaborates upon the maker movement, which has spurred people’s capacity to participate and has provided...journal article 2019

Jaśkiewicz, T.J. (author), Mulder, I. (author), Morelli, Nicola (author), Pedersen, Janice S. (author)This paper investigates the opportunities of leveraging a hackathon format to empower citizens by increasing their abilities to use open data to improve their neighbourhoods and communities. The presented discussion is grounded in five civic hackathon case studies organised in five European cities. The research revealed specialised learning and...journal article 2019

Reitsma, J.P. (author), van Paassen, M.M. (author), Mulder, Max (author)Designing interfaces for effective decision-making supports for complex, dynamic systems is a challenging task. Besides the already challenging task of determining the visual form, the task of defining the content of these supports can be even more demanding. Especially for an unstable and complex work domain with multiple stakeholders and...journal article 2019

Fu, W. (author), van Paassen, M.M. (author), Mulder, Max (author)Haptic displays can greatly facilitate manual control tasks. Their capacity of allowing the operator to perceive the desired dynamics is an important design parameter. However, attempts to evaluate haptic displays on the basis of what dynamics humans actually perceive are scarce. This paper proposes a two-step framework which incorporates the...journal article 2019

Mulder, K.F. (author)The challenge of sustainable development requires cities to aim for drastic improvements in the systems that support its vital functions. Innovating these systems can be extremely hard, and might take lots of time. A transparent and democratic strategy is important to guarantee support for change. Such a process should aim at developing...journal article 2019

Huijbrechts, Erik-Jan (author), Koolstra, H.J. (author), Mulder, J.A. (author)Vmcg, or ground minimum control speed, is established by aircraft manufacturers during the aircraft certification process. Vmcg is used as a limiting speed for V1 (decision speed) when performing takeoff performance calculations. Performance calculations on contaminated and slippery runways will result in a V1 speed equal to Vmcg-limited V1 for...journal article 2019
