Papaioannou, G. (author), Maroof, Vallan (author), Jerrelind, Jenny (author), Drugge, Lars (author)Effective emission control technologies and eco-friendly propulsion systems have been developed to decrease exhaust particle emissions. However, more work must be conducted on non-exhaust traffic-related sources such as tyre wear. The advent of automated vehicles (AVs) enables researchers and automotive manufacturers to consider ways to further...journal article 2024

NATHANAEL, KONSTANTINOS (author)Despite the technological improvements in the dredging industry in the last decades, there are components that have not been investigated accordingly. One of them is the bow coupling bend pipe which can be found on trailing suction hopper dredgers. In contrast to most pipelines, the specific bend pipe is not only a means of transport for the...master thesis 2023

Li, S. (author), Naeimi, M. (author), He, C. (author), Dollevoet, R.P.B.J. (author), Li, Z. (author)The mechanism of rail short pitch corrugation has remained elusive in the past. The damage mechanisms of the corrugation are reported to be differential wear or plastic deformation. The former has been extensively studied, while the plastic deformation, especially under multiple wheel passages has been seldom studied. To uncover the facts...journal article 2023
