Savoldi, F. (author)This article examines the increasingly conflictual relationship between ports and their surrounding communities at a time of wide-reaching infrastructural expansion. It highlights how the centralization of power and logistical gigantism produce deterritorializing frictions, decoupling inhabitants from their territories and creating the...journal article 2024

Heinen, Jan T. (author), Brockie, S.G. (author), ten Broek, Raymund (author), van der Kruk, E. (author), Moore, J.K. (author)The ollie is the base aerial human–board maneuver, foundational to most modern skateboarding tricks. We formulate and solve an optimal control problem of a two-dimensional simplified human model and a rigid body skateboard with the objective of maximizing the height of the ollie. Our solution simultaneously discovers realistic human-applied...journal article 2024

Rozendaal, M.C. (author), Dijkstra, Y.M. (author), Schuttelaars, H.M. (author)The water motion computed using 3D and 2DH models in tidally dominated shallow waters can, in some cases, differ significantly. In 2DH models, bed friction is typically parametrised in terms of the depth-averaged velocity, whereas in 3D models, typically the near-bed velocity is used. This difference causes the bed shear stress in 2DH models...journal article 2024

Molenkamp, T. (author), Tsetas, A. (author), Tsouvalas, A. (author), Metrikine, A. (author)Vibratory offshore pile driving offers a potential solution for reducing the underwater noise generated during the installation of foundation piles compared to using impact hammers. Existing noise prediction models are specifically tailored to impact pile driving scenarios. This paper introduces a novel methodology for underwater noise...journal article 2024

Tao, T. (author), Roy, Spandan (author), De Schutter, B.H.K. (author), Baldi, S. (author)In this work we propose a new practical synchronization protocol for multiple Euler Lagrange (EL) systems without structural linear-in-the-parameters (LIP) knowledge of the uncertainty and where the agents can be interconnected before control design by unknown state-dependent interconnection terms. This setting is meant to overcome two...journal article 2024

(author), Wiertlewski, M. (author), Redmond, Stephen J. (author), Birznieks, Ingvars (author)Abstract: When manipulating objects, humans begin adjusting their grip force to friction within 100 ms of contact. During motor adaptation, subjects become aware of the slipperiness of touched surfaces. Previously, we have demonstrated that humans cannot perceive frictional differences when surfaces are brought in contact with an immobilised...journal article 2024

Ujjaini Kempaiah, K. (author)A flying aircraft consumes fuel to overcome air resistance during its motion. A significant part of this consumption (55%) is due to turbulent skin friction arising at the interface of the aircraft surface and the air. The current work aims to develop and investigate relevant turbulent skin-friction reduction techniques and assist in advancing...doctoral thesis 2023

van Dam, Nathalie (author)Propulsion power is an important metric in wheelchair racing. For a flat surface, it can be estimated from the sum of friction power and kinetic power. Usually, to determine friction power, the rolling and air drag coefficient first need to be determined with coast-down tests or other time-consuming methods. The aim of this paper was to...master thesis 2023

MAHAJAN, SAURABH (author)Structural joints influence the design strength, material requirement of a structure. Structural joints experience damping dissipation due to friction damping or hysteresis damping. Damping is often used for reducing the vibrations in a structure. However, large amount of energy dissipation leads to deterioration of the material used for...master thesis 2023

van Delft, Youri (author)Background: Through technological development, a variety of mechanical finger joints have been produced. No current design takes inspiration from nature enough to develop a synovial inspired single finger joint. Due to this the potential performance is unknown, while natural joints out perform mechanical finger joints with respects to the...master thesis 2023

Schuijt, Rinus (author)In this thesis, the friction performance of polyurethane tensioner pads used in offshore pipe-laying was investigated. Tensioner pads are used in pipe-lay to create tension in a pipe. The need to understand the pads better is because of the increased use of pipe coatings and pipe lay in deeper waters. Deep water leads to more pipe tension, and...master thesis 2023
