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

Wigmans, Bram (author)This paper examines whether complex high-dimensional data that describes the dynamics of a cantilever beam can be transformed into a less complex system. In particular, the transformation that is examined is the reduction of the dimension. An essential aspect of this study involves the implementation of a linear autoencoder, which is a type of...bachelor thesis 2023

Burghoorn, Rick (author)Air bearings are a vital component to high tech machines and have been in widespread use since the 1960s. They provide near frictionless motion, have high stiffness and a near infinite lifetime. When looking at existing literature the influence of the porosity on the dynamic characteristics has not been researched in depth. Especially when...master thesis 2023

Bouman, Niels (author)Two-dimensional (membrane) materials have been receiving much scientific attention due to their unique material properties that can be used to study the smallest physical phenomena. One such material is graphene, perceived as the holy grail in material physics, due to its unique material properties. Its aspect ratio diminishes the bending...master thesis 2023

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

Wang, Zelin (author)In 2021, China is already the largest electric vehicle (EV) market with more than half of global sales. Compared to the situation ten years ago, EV development in China has experienced a huge growth almost from nothing. This development is a complex socio-technical transition process, which cannot be simplified as technology progress or business...master thesis 2022

Halvorsen, Stijn (author)Wind energy plays an essential role in the transition to a sustainable future and wind turbines allow us to utilize it. Wind turbines are often installed in close proximity to make the best use of the given space and to save costs. This also has the disadvantage that the turbines influence each other due to wakes. This is where wind farm control...master thesis 2022

Angela, Giovan (author)Machine learning classifiers have become a household tool for banks, companies, and government institutes for automated decision-making. In order to help explain why a person was classified a certain way, a solution was proposed that could generate these counterfactual explanations. Several generators have been introduced and tested but include...bachelor thesis 2022

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 Waas, Tom (author)Non-photochemical laser-induced nucleation (NPLIN) is a process where a crystalline phase is formed out of solution by exposure to a laser beam. In NPLIN, the nucleation probability is strongly dependent on the beam intensity and weakly dependent on the wavelength. NPLIN offers a feasible alternative to energy-intensive industrial...bachelor thesis 2019

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

Jockin, Pieter (author)The transition to a circular economy requires drastic changes to the economy. A tool for macro-economic analysis of structural changes in the economy, input-output analysis, lacks dynamic features. This thesis set out to integrate dynamic features representing demand change and technological change. A conceptual model is designed that integrates...master thesis 2018
