van der Sanden, B. (author), Geilen, M. (author), Reniers, M. (author), Basten, T. (author)A key challenge in the synthesis and subsequent analysis of supervisory controllers is the impact of state-space explosion caused by concurrency. The main bottleneck is often the memory needed to store the composition of plant and requirement automata and the resulting supervisor. Partial-order reduction (POR) is a well-established technique...article 2022

Müller, R.A.J. (author), von Benda-Beckmann, A.M. (author), Halvorsen, M.B. (author), Ainslie, M.A. (author)Regulations for underwater anthropogenic noise are typically formulated in terms of peak sound pressure, root-mean-square sound pressure, and (weighted or unweighted) sound exposure. Sound effect studies on humans and other terrestrial mammals suggest that in addition to these metrics, the impulsiveness of sound (often quantified by its kurtosis...article 2020
