Dell’Orto, G. (author), Mastinu, G. (author), Happee, R. (author), Moore, J.K. (author)The paper presents measurements of the lateral force and self-aligning torque from cargo and city bicycle tyres. Based on the experimental data, we have determined the parameters for the Magic Formula model, for lateral force and self-aligning torque. We performed tests with VeTyT, an indoor test rig specific for bicycle tyres, under...journal article 2024

Wu, Jun (author), Miller, Thomas E. (author), Cicirello, A. (author), Mortimer, Beth (author)Often overlooked, vibration transmission through the entire body of an animal is an important factor in understanding vibration sensing in animals. To investigate the role of dynamic properties and vibration transmission through the body, we used a modal test and lumped parameter modelling for a spider. The modal test used laser vibrometry...journal article 2023

Tang, Tie Qiao (author), Nicolas, Alexandre (author), Lee, Seungjae (author), Daamen, W. (author), Song, Ziqi (author)In the study of pedestrian dynamics, the consideration of group behaviours is essential, as group interaction within crowds is a common phenomenon and significantly influences pedestrian behaviours. This special issue highlights the importance of pedestrian group behaviours and examines the subject using a wide range of methods, such as...contribution to periodical 2023

Haasnoot, Jelle (author), Happee, R. (author), van der Wijk, V. (author), Schwab, A.L. (author)Bicycle simulators have been the subject of considerable research, however, few of these attempts have integrated direct balance control and realistic freedom of motion to deliver a real-world dynamic cycling experience. This study presents the BIKE (Bicycle Intrinsic Kinematics Emulator) system, a kinematic bicycle simulator, developed with...journal article 2023

Zekollari, H. (author), Huss, M. (author), Farinotti, D. (author), Lhermitte, S.L.M. (author)Glaciers play a crucial role in the Earth System: they are important water suppliers to lower-lying areas during hot and dry periods, and they are major contributors to the observed present-day sea-level rise. Glaciers can also act as a source of natural hazards and have a major touristic value. Given their societal importance, there is large...review 2022

Li, Q. (author), Askarinejad, A. (author), Gavin, Kenneth (author)In this study, a total number of 20 centrifuge tests were carried out to investigate monopile behaviour under lateral cyclic loading. The instrumented model pile simulates an offshore wind turbine foundation with an embedment ratio of 5 installed in sand layers with two relative densities of 80% and 50%. The influence of the directional...journal article 2021

Zekollari, H. (author), Huss, Matthias (author), Farinotti, Daniel (author)Glaciers in the European Alps rapidly lose mass to adapt to changes in climate conditions. Here, we investigate the relationship and lag between climate forcing and geometric glacier response with a regional glacier evolution model accounting for ice dynamics. The volume loss occurring as a result of the glacier-climate imbalance increased...journal article 2020

Kementzetzidis, E. (author), Metrikine, A. (author), Versteijlen, Willem Geert (author), Pisano, F. (author)With the offshore wind industry rapidly expanding worldwide, geotechnical research is being devoted to foundation optimisation - most intensively for large-diameter monopiles. The analysis and design of monopiles still suffers from significant uncertainties in relation to cyclic/dynamic loading conditions. The aim of this work is to shed new...journal article 2020

Gomez, Clara (author), Hernandez, Alejandra C. (author), Derner, Erik (author), Barber, Ramon (author), Babuska, R. (author)Relying on static representations of the environment limits the use of mapping methods in most real-world tasks. Real-world environments are dynamic and undergo changes that need to be handled through map adaptation. In this work, an object-based pose graph is proposed to solve the problem of mapping in indoor dynamic environments with mobile...journal article 2020

van der Spaa, L.F. (author), Wolfslag, W.J. (author), Wisse, M. (author)In electrically actuated robots most energy losses are due to the heating of the actuators. This energy loss can be greatly reduced with parallel elastic actuators, by optimizing the elastic element such that it delivers most of the required torques. Previously used optimization methods relied on parameterizing the spring characteristic,...journal article 2019

Schwab, A.L. (author), Dialynas, G. (author), Happee, R. (author)The bicycle, being unstable at low speed and marginally stable at high speed, is sensitive to lateral perturbations. One of the major lateral perturbations is crosswind, which can lead to accidents and fatalities. Here we investigate the effect of crosswind on the lateral dynamics and control of the bicycle in a wide range of forward speeds and...conference paper 2018

A string-based representation and crossover operator for evolutionary design of dynamical mechanismsKuppens, P.R. (author), Wolfslag, W.J. (author)Robots would perform better when their mechanical structure is specifically designed for their designated task, for instance by adding spring mechanisms. However, designing such mechanisms, which match the dynamics of the robot with the task, is hard and time consuming. To assist designers, a platform that automatically designs dynamical...journal article 2018

He, D. (author), Pang, Y. (author), Lodewijks, G. (author)Belt conveyors play an important role in continuous dry bulk material transport, especially at the mining industry. Speed control is expected to reduce the energy consumption of belt conveyors. Transient operation is the operation of increasing or decreasing conveyor speed for speed control. According to literature review, current research...journal article 2016

Plooij, M.C. (author)Since the industrial revolution, machines have taken over many tasks from humans, increasing labor productivity and prosperity. In the 20th century, the introduction of robots created a second wave of automation, increasing the labor productivity even further. In order to create a third wave of automation, it is necessary to develop a new...doctoral thesis 2015
