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

Ren, J. (author), Fu, Song (author), Pecnik, Rene (author)The objective of this work is to investigate linear modal and algebraic instability in Poiseuille flows with fluids close to their vapour-liquid critical point. Close to this critical point, the ideal gas assumption does not hold and large non-ideal fluid behaviours occur. As a representative non-ideal fluid, we consider supercritical carbon...journal article 2019

Fu, W. (author), van Paassen, M.M. (author), Mulder, Max (author)Most haptic interfaces developed for aircraft control provide haptic support as an additional force on the control manipulator. This study revisits the active manipulator, which is a design concept that is different from but complementary to existing haptic interfaces. This control device sends the force that the pilot exerts on it to the...journal article 2019

Fu, A. (author), Mazo, M. (author)Periodic event-triggered control (PETC) [13] is a version of event-triggered control that only requires the measurement of the plant output periodically instead of continuously. In this note, we present a construction of timing models for these PETC implementations to capture the dynamics of the traffic they generate. In the construction, we...journal article 2019

Man, Z. (author), Dou, X. (author), Fu, Shenggui (author)We show that elongating a tightly focused field in the direction perpendicular to the optical axis is possible. We demonstrate our approach by specially shaping the Pancharatnam–Berry (PB) phase. Moreover, the analytical formulae required to calculate the strength vectors and energy flux of the three-dimensional electromagnetic fields near...journal article 2019

Fu, W. (author), van Paassen, M.M. (author), Abbink, D.A. (author), Mulder, Max (author)Time delays in haptic teleoperation affect the ability of human operators to assess mechanical properties (damping, mass, and stiffness) of the remote environment. To address this, we propose a unified framework for human haptic perception of the mechanical properties of environments with delayed force feedback. In a first experiment, we...journal article 2019

Measuring surface charge: Why experimental characterization and molecular modeling should be coupledHartkamp, Remco (author), Biance, Anne-Laure (author), Fu, Li (author), Dufrêche, Jean François (author), Bonhomme, Oriane (author), Joly, Laurent (author)Surface charge controls many static and dynamic properties of soft matter and micro/nanofluidic systems, but its unambiguous measurement forms a challenge. Standard characterization methods typically probe an effective surface charge, which provides limited insight into the distribution and dynamics of charge across the interface, and which...journal article 2018
