Krugla, M. (author), Offerman, S.E. (author), Sietsma, J. (author), Hanlon, Dave N. (author)The production reality of sheet steels from casting to the end product is such that in the cases of ultra- and advanced high-strength steels, we have to deal with the segregation of elements on macro- and microlevels. Both can have a significant impact on the microstructure formation and resulting properties. There are several production stages...journal article 2024

Men, Jinkun (author), Chen, Guohua (author), Reniers, G.L.L.M.E. (author), Wu, Yue (author), Huang, Hailing (author)An earthquake-triggered fire domino scenario (E-FDS) is an example of a typical multi-hazard coupling event. The seismic damage can affect the fire resistance of engineering structures, leading to significant mutually amplified phenomena. In this work, a two-stage experimental program is designed to expound the earthquake-fire coupling...journal article 2024

Zheng, L. (author), Hamaza, S. (author)Drones have been increasingly used in various domains, including ecological monitoring in forests. However, the endurance and noise of drones have limited their deployment to short flight missions above canopies. To address these limitations, we introduce ALBERO: a framework comprising a mechanical solution and an optimal planner to realise...journal article 2024
