Plooij, M.C. (author), Wolfslag, W.J. (author), Wisse, M. (author)This paper identifies the class of actuators called clutched elastic actuators (CEAs). CEAs use clutches to control the energy flow into springs. CEAs in exoskeletons, prostheses, legged robots, and robotic arms have shown the ability to reduce the energy consumption and motor requirements, such as peak torque and peak power. Because of those...journal article 2017

Ramos-Llorden, Gabriel (author), den Dekker, A.J. (author), Van Steenkiste, Gwendolyn Van (author), Jeurissen, Ben (author), Vanhevel, Floris (author), Audekerke, Johan Van (author), Verhoye, Marleen (author), Sijbers, Jan (author)In quantitative MR T1 mapping, the spin-lattice relaxation time T1 of tissues is estimated from a series of T1-weighted images. As the T1 estimation is a voxel-wise estimation procedure, correct spatial alignment of the T1-weighted images is crucial. Conventionally, the T1-weighted images are first registered based on a general-purpose...journal article 2017

Klaassen, Steven W.B. (author), van der Seijs, M.V. (author), de Klerk, D. (author)This paper introduces SEMM: a method based on Frequency Based Substructuring (FBS) techniques that enables the construction of hybrid dynamic models. With System Equivalent Model Mixing (SEMM) frequency based models, either of numerical or experimental nature, can be mixed to form a hybrid model. This model follows the dynamic behaviour of a...journal article 2017

Parayil Venugopalan, S. (author), Mueser, Martin H. (author), Nicola, L. (author)Metals deform plastically at the asperity level when brought in contact with a counter body even when the nominal contact pressure is small. Modeling the plasticity of solids with rough surfaces is challenging due to the multi-scale nature of surface roughness and the length-scale dependence of plasticity. While discrete-dislocation plasticity ...journal article 2017

Liu, Y. (author), van der Meer, F.P. (author), Sluys, Lambertus J. (author)In this paper, the thick-level-set method is used to model stable and unstable (stick/slip) crack propagation in the dynamic double cantilever beam (DCB) test for unidirectional composite laminates. The thick-level-set method uses a predefined damage profile to describe the fracture process zone and allows<br/>for accurate evaluation of the...conference paper 2017

Lehmann-Willenbrock, Nale (author), Hung, H.S. (author), Keyton, Joann (author)This special issue on advancing interdisciplinary collaboration between computer scientists and social scientists documents the joint results of the international Lorentz workshop, “Interdisciplinary Insights into Group and Team Dynamics,” which took place in Leiden, The Netherlands, July 2016. An equal number of scholars from social and...journal article 2017

Meissner, F.V.M. (author)Tracing the link between population flux and the regulation of migration, this paper develops the argument that immigration status differentiations impact not only on categorical multiplicities but also on contingent dynamics in urban migration-related diversity. A better understanding of those contingencies is central to discussing processes...journal article 2017

Staats, B.R. (author), Diakite, A.A. (author), Voûte, R.L. (author), Zlatanova, S. (author)Automatic generation of indoor navigable models is mostly based on 2D floor plans. However, in many cases the floor plans are out of date. Buildings are not always built according to their blue prints, interiors might change after a few years because of modified walls and doors, and furniture may be repositioned to the user's preferences....conference paper 2017

Cao, Xi (author), Gruiter, Rick de (author), van Oorschot, Ralph (author), Baldi, S. (author), Hassan HosseinNia, S. (author), Ghatkesar, M.K. (author)A hollow microcantilever is used instead of a conventional microcantilever to dispense and aspirate liquids in the femto-litre (10<sup>-15</sup> L) volume range in an atomic force microscope (AFM) setup. The inherent force sensing capability of the cantilever is used to monitor the fluid manipulation in-situ. At this small scale, parameters...journal article 2017

Fognini, A.W. (author), Michlmayr, T. U. (author), Vaterlaus, A. (author), Acremann, Y. (author)The ultrafast demagnetization process allows for the generation of femtosecond spin current pulses. Here, we present a thermodynamic model of the spin current generation process, based on the chemical potential gradients as the driving force for the spin current. We demonstrate that the laser-induced spin current can be estimated by an easy...journal article 2017

Dong, J. (author), Zhang, Kouchi (author)In lighting systems consisting light-emitting diodes (LEDs), excessive temperature is a main cause of degraded luminous efficacy, which leads to reduced average illuminance and distorted illumination rendering. Modeling the thermal dynamics of LEDs is hence essential in designing thermal dissipators and controllers for maintaining constant...journal article 2017

Paltrinieri, Nicola (author), Reniers, G.L.L.M.E. (author)The accident that occurred in Seveso in 1976 changed our approach to risk assessment forever. For instance, it led to drafting specific European directives to prevent major accident hazards. Their focus is on industrial sites handling dangerous substances and denominated “Seveso sites”. Their operators have the obligation to provide specific...journal article 2017

Vegt, I. (author)The fracture properties of concrete are rate dependent. In this thesis the results on tensile tests at static, moderate and high loading rate are presented. The results show the influence of the loading rate not only the tensile strength, but also on the fracture energy, stress-defromation relation and fracture parameters, like fracture lengths...doctoral thesis 2016
