van den Boom, S.J. (author), van Veen, D. (author), Diederen, A. (author), Gartner, T. (author), Weerheijm, J. (author)This work investigates the impact protection properties of auxetic metamaterial lattices for impact velocities between 40 and 100 m/s, in a 1D impact scenario. After successful previous experiments and simulations with lower impact velocities and nylon samples, we now investigate whether or not the auxetic properties of such metamaterial are...conference paper 2022

Jacobs, P. (author), Khoury, E. (author), Klerk, M. (author), Valkema, M. (author)Existing schools are badly insulated and often suffer from inadequate ventilation and cold in winter and too high temperatures in summer. Further schools nearby a busy road require high efficiency filtering, which traditionally lead to high pressure drops and installation noise. Current ventilation systems suitable for renovation often require...article 2022

Jacobs, P. (author), Kemp, R.E.J. (author), Vijlbrief, O. (author)In well isolated dwellings especially with multiple residents domestic hot water (DHW) accounts often for more than 50% of the energy consumption.Currently there exist shower heat recovery units which recover 40 – 70 percent of the heat in the shower water. This efficiency can drop due to fouling of the heat exchanger, which is often not...article 2022

Sipma, J.M. (author)In dit onderzoek is het nieuwbouw-, sloop- en transformatietempo voor de in de BAG onderscheiden gebruiksfuncties bepaald. De BAG (Basisregistratie Adressen en Gebouwen) omvat alle gebouwen van Nederland. Er worden door de BAG 11 gebruiksfuncties onderscheiden. Voorbeelden zijn de gebruiksfuncties ‘kantoor’, ‘onderwijs’, ‘zorg’ en ‘woon’. De...report 2022

(author)Container terminal capacity is often limited by (in)efciency bottlenecks. This paper provides the design and proof of concept for the bottleneck mitigation cycle (BMC), consisting of three steps: bottleneck classifcation, detection and alleviation. While, often, the literature only focuses on alleviation of a single bottleneck and ignores...article 2022

Deul, M.L. (author), van Lieshout, P. (author), Werter, N.P.M. (author)An accurate fatigue life prediction is vital for the effectiveness and safety of a ship structure. The fatigue limit state is typically governing and con servatism is included to provide for a safe design. On the other side, minimizing conservatism is favourable, for reasons of cost, stability and payload (i.e. weight). The fatigue life...conference paper 2022

Kemper, F. (author), Geurts, C.P.W. (author)For the modeling of stochastic structural responses due to wind gusts, reasonable assumptions for the aerodynamic admittance are elementary. However, still a large variety of corresponding models exists and it lacks of validation and reliable model estimation studies based on real-data.

Bronkhorst, A.J. (author), Moretti, D. (author), Geurts, C.P.W. (author)Wind-induced vibrations are an important aspect in high-rise building design. The structural properties that influence vibrations are the mass and stiffness of the building and the foundation. These properties are difficult to predict in the design, resulting in inaccurate predictions of the dynamic response. As a first step towards better...conference paper 2022
