Jiang, Q. (author), Bertolo, V.M. (author), Pallaspuro, S. (author), Popovich, V. (author), Sietsma, J. (author), Walters, C.L. (author)Multi-barrier cleavage models consider cleavage fracture which is characterized by a series of microscale events. One of the challenges for multi-barrier cleavage models is the strong variations of cleavage parameters across different types of steels. The source and magnitude of the variations have not been studied systematically. In the current...article 2023

(author)High-velocity friction experiments on simulated fault gouges sheared at high normal stress and to low displacement are particularly relevant to induced seismicity, which is becoming an important topic in fault mechanics. Using a new, improved set-up, which allows simulation of fault stress and fluid pressure ((Formula presented.)) conditions...article 2023

Zhang, X. (author), Noel-Hermes, N. (author), Ferrari, G. (author), Hoogeland, M.G. (author)Corrosion of mooring chains is regarded as one of main threats to the offshore mooring systems. Localized corrosion is even more dangerous than uniform corrosion because it may not show significant mass loss but it can cause stress concentration and initiate cracks under force, leading to accelerated degradation of mooring chains. Localized...article 2022

M. Sanchez, M. (author), Pogosov, D. (author), Silvas, E. (author), Mocanu, D.C. (author), Elfring, J. (author), van de Molengraft, R. (author)An automated vehicle (AV) must always have a correct representation of the drivable space to position itself accurately and operate safely. To determine the drivable space, current research focuses on single sources of information, either using pre-computed high-definition maps, or mapping the environment online with sensors such as LiDARs or...article 2022

Diran, D.D.D. (author), Hoekstra, M. (author), van Veenstra, A.F.E. (author)The potential of the use of data to help improve policymaking is increasingly recognized by governments, especially to address societal challenges. One of those societal challenges is the energy transition, which happens for a large part at the local government level. However, within the literature little is known about which type of...conference paper 2022

Martinez, S.H. (author), Harmsen, R. (author), Menkveld, M. (author), Faaij, A.P.C. (author), Kramer, G.J. (author)Municipalities are key actors in planning and enabling the transition in the built environment to sustainable heat systems. Literature on the municipal experiences in the early phases of the heat transition is scarce. This paper addresses this gap by depicting the approaches of twenty-eight municipalities in the Netherlands. It aims to assess...article 2022

de Gijsel, S.L. (author), Vijn, A.R.P.J. (author), Tan, R.G. (author)This paper proposes an algorithm to localize a magnetic dipole using a limited number of noisy measurements from magnetic field sensors. The algorithm is based on the theory of compressed sensing, and exploits the sparseness of the magnetic dipole in space. Beforehand, a basis consisting of magnetic dipole fields belonging to individual dipoles...article 2022

van der Burg, E. (author), Hogervorst, M.A. (author), Toet, A. (author)Natural scenes are typically highly heterogeneous, making it difficult to assess camouflage effectiveness for moving objects since their local contrast varies with their momentary position. Camouflage performance is usually assessed through visual search and detection experiments involving human observers. However, such studies are time...conference paper 2022

Burghouts, G.J. (author), Hillerström, F.H.J. (author)Current object recognition techniques are based on deep learning and require substantial training samples in order to achieve a good performance. Nonetheless, there are many applications in which no (or only a few) training images of the targets are available, whilst they are well-known by domain experts. Zero-shot learning is used in use cases...conference paper 2021

Cornelissen, R. (author), Maljaars, J. (author), Hofmeyer, H. (author)Curved aluminium extrusions are applied in a wide range of industrial applications. Because extrusions are initially straight, an additional process is required to curve the product. Undesired wrinkling of the plate part at the inner radius is frequently observed during the curving process. Wrinkling has already been extensively studied for the...article 2021

(author)Purpose: Ventilated vests are developed to reduce thermal stress by enhancing convective and evaporative cooling from skin tissue underneath the vest. The purpose of this study is to investigate whether thermal stress is equal when a ventilated vest is worn compared to a no-vest situation with similar dry thermal resistance.
