Peysakhovich, V. (author), Ledegang, W. (author), Houben, M. (author), Groen, E. (author)Eye movements analysis has great potential for understanding operator behaviour in many safety-critical domains, including aviation. In addition to traditional eye-tracking measures on pilots’ visual behavior, it seems promising to incorporate machine learning approaches to classify pilots’ visual scanning patterns. However, given the multitude...conference paper 2022

Tabakovic, A. (author), Faloon, C. (author), O'Prey, D. (author)Conductive alginate capsules encapsulating a bitumen rejuvenator (HealRoad capsules) has demonstrated good healing abilities in pure bitumen and mortar mixes. HealRoad capsules can efficiently heal damage via induction heating. They also release the encapsulated rejuvenator, thereby rejuvenating aged bitumen. These findings indicate that...article 2022

Burggraaf, J. (author), Groeneweg, J. (author), Sillem, S. (author), van Gelder, P. (author)When a train passes a red aspect, this is called a Signal Passed at Danger event or SPAD. Sometimes it is easy to identify the SPAD cause but in other cases it is unclear why the incident occurred, especially if the system operated as usual and the train driver was trained and experienced just like his or her colleagues. In previous research,...article 2022

Miermans, C.J.H. (author), Dijkmans, E. (author), Krystek, P.W. (author)The ability to track & trace materials is a key feature in the entire chain, and it ensures circularity principles. Examples from plastic recycling show the enormous added value that analytical technology can have for the circular economy. During polymer production and recycling processes, pigments can be added for different purposes; e.g. as...article 2020
