Mulder, B. (author), La Rocca, G. (author), Schut, J. (author), Verhagen, W.J.C. (author)A short lead time of the Product Development Process (PDP) is an important competitive advantage for companies. Design automation solutions provide a means to reduce the lead time and improve quality, but their development requires some investment. Before a company can commit to the development of an automation initiative, it requires an...conference paper 2015

Leurs, B. (author), Schelling, J. (author), Mulder, I.J. (author)a problem due to a lack of space, a group of 50 design students had to move to another building. Having a dedicated space in an historical building turned the initial setback into an opportunity. Design students usually do not have the luxury of having their own design studio. By observing and interviewing the students over a period of 5 months,...conference paper 2013

Reitsma, J.P. (author), van Paassen, M.M. (author), Mulder, M. (author)The glass cockpit and EFB enable new ways of information presentation and interaction on the flight deck of modern commercial jets. This information supports crews in flight plan management, which essentially entails evaluating the plan against (ever-changing) flight constraints and, if necessary, modifying it. Flight constraints emerge from the...conference paper 2019

Mulder, F.A. (author), Verlinden, J.C. (author), Dukalski, R.R. (author)This paper explores the amount of motion simulation required to influence presence and immersion on a dinghy sailing simulator. We specifically focused on the effects of roll, pitch and heave, when sailing an course with up-, side-and down-wind sections in a virtual environment. A real dingy was mounted on a 6 Degrees of Freedom (DOF) Stewart...conference paper 2012

Mulder, W.A. (author)Migration velocity analysis for the two-way wave equation based on focusing extended migration images at zero subsurface offset are sensitive to the presence of multiples. Even after thorough multiple suppression, remnant multiple energy can lead to conflicting events that will focus at different velocities, one for the primary and another for...conference paper 2013

Lombaerts, T.J.J. (author), Looye, G.H.N. (author), Chu, Q.P. (author), Mulder, J.A. (author)This paper describes how the previously developed concept of Pseudo Control Hedging (PCH) can be integrated in a Fault Tolerant Flight Controller (FTFC) as a safe flight envelope protection system of the first degree. This PCH algorithm adapts the reference model for the system output in case of unachievable commands due to control input...conference paper 2010

Shamasundar, R. (author), Al-Khoury, R.I.N. (author), Mulder, W.A. (author)We investigated one-dimensional numerical dispersion curves and error behaviour of four finite-element schemes with polynomial basis functions: the standard elements with equidistant nodes, the Legendre-Gauss-Lobatto points, the Chebyshev-Gauss-Lobatto nodes without a weighting function and with. Mass lumping, required for efficiency reasons and...conference paper 2015

De Weerdt, E. (author), Van Kampen, E. (author), Chu, Q.P. (author), Mulder, J.A. (author)Trajectory optimization has been a large field of research for many years. The drawback is that for non-convex, constrained problems practically all available solvers cannot guarantee that the globally optimal trajectory is found. Interval analysis based solvers however can provide this guarantee. Interval analysis has been applied to trajectory...conference paper 2011

Pool, D.M. (author), Damveld, H.J. (author), Van Paassen, M.M. (author), Mulder, M. (author)This paper describes the preliminary results of an effort to compile data from a large number of studies that investigated the effects of variations in motion filter settings on pilot behavior. The main objective of this study is to formulate a set of mathematical rules that will allow for the tuning of behavioral pilot models to a certain...conference paper 2011

Mulder, J.P.M. (author), Stive, M.J.F. (author)Our coast essentially consists of sand from the bottom of the North Sea that was laid there by rivers in previous interglacial periods. Increasing sea levels have meant that this source has gradually almost ceased to exist with build-up reversing to break down. The balance between the supply and demand for sediment is currently negative but sand...conference paper 2011

Van Wieringen, A.T. (author), Pool, D.M. (author), Van Paassen, M.M. (author), Mulder, M.

Previous studies that attempted to motivate choices in the motion cueing strategy for pitch maneuvering based on...conference paper 2011

Pisupati, P.B. (author), Mulder, W.A. (author), Drijkoningen, G.G. (author), Reijnen, R. (author)In the near-surface with unconsolidated soils, shear properties can be well imaged, sometimes better than P-wave properties. To facilitate ground prediction ahead of a tunnel boring machine (TBM), active ‘surveys’ with shear-wave vibrators are carried out during boring. In such surveys, only a few shear-wave vibrators can be placed in front of...conference paper 2015

Van Kampen, E. (author), Chu, Q.P. (author), Mulder, J.A. (author)This paper applies interval optimization to the fixed-time multiple impulse rendezvous and docking problem. Current methods for solving this type of optimization problem include for example genetic algorithms and gradient based optimization. Unlike these methods, interval methods can guarantee that the globally best solution is found for a given...conference paper 2010

We investigate to what extent there is an association between the level of fertility and the organization of home-ownership in western countries. We distinguish four home-ownership regimes, based on the share of owner-occupied housing and access to mortgages. We argue that one home-ownership regime is...conference paper 2006

Yu, H. (author), Mulder, J.A.
