(author), de Dominicis, L. (author)Counter terrorism is a huge challenge for public spaces. Therefore, it is essential to support early detection of threats, such as weapons or explosives. An integrated fusion engine was developed for the management of a plurality of sensors to detect threats without disrupting the flow of commuters. The system improves security of soft targets ...article 2023

(author)Wearable sensors offer new opportunities for the early detection and identification of toxic chemicals in situations where medical evaluation is not immediately possible. We previously found that continuously recorded physiology in guinea pigs can be used for early detection of exposure to an opioid (fentanyl) or a nerve agent (VX), as well as...article 2023

Dimitrovski, T. (author), Bergman, T. (author), Zuraniewski, P. (author)The use of Machine Learning in many control and management processes is rising fast. This is especially true for the management of cloud native applications and for anomaly detection in cyber-security mechanisms. However, it has been shown that ML is an attack surface on its own, especially when the attack is performed by another ML system....conference paper 2023

(author), Farha, O.K. (author)In the case of an incident with nerve agents, the timely and ready detection and identification of such a substance on suspected surfaces is essential. However, the detection of low levels of nerve agents on a surface is a considerable challenge for conventional detection equipment, especially with VX, a highly toxic nerve agent with low...article 2022

Berghuis, N.F. (author), Mars-Groenendijk, R.H. (author), Busker, R.W. (author), Paauw, A. (author), van Leeuwen, H.C. (author)CRISPR–Cas (CC)-based detection technologies have some exceptional features, which hold the promise of developing into the nextgeneration diagnostic platforms. One of these features is the ability to trigger non-specific single-stranded DNA/RNA cleavage activity after specific target recognition and Cas enzyme activation. This cleavage activity...article 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

van der Burg, E. (author), Hogervorst, M.A. (author), Toet, A. (author)Natural scenes are typically highly heterogeneous, making it difficult to assess camouflage effectiveness for moving objects since their local contrast varies with their momentary position. Camouflage performance is usually assessed through visual search and detection experiments involving human observers. However, such studies are time...conference paper 2022
