(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)Hepatocellular carcinoma (HCC) in the setting of non-alcoholic fatty liver disease (NAFLD)-related cirrhosis and even in the pre-cirrhotic state is increasing in incidence. NAFLD-related HCC has a poor clinical outcome as it is often advanced at diagnosis due to late diagnosis and systemic treatment response is poor due to reduced immune...article 2023

van Rooijen, A.L. (author), Bouma, H. (author), Baan, J. (author), van Leeuwen, M.C. (author)Person re-identification (Re-ID) can be used to find the owner of lost luggage, to find suspects after a terrorist attack, or to fuse multiple sensors. Common state-of-the-art deep-learning technology performs well on a large public dataset but it does not generalize well to other environments, which makes it less suitable for practical...conference paper 2022

(author)Virtual reality (VR) simulation tools, in combination with miniaturized sensor and geotechnology, represent an opportunity to prepare high-risk professionals better for uncertain situations. In the current study, we tested whether VR preparation for a police surveillance task leads to increased performance and decreased stress, workload, and a...article 2022

(author)Person re-identification (Re-ID) is a valuable technique because it can assist in finding suspects after a terrorist attack. However, the machine learning algorithms for person Re-ID are usually trained on large datasets with images of many different people in a public space. This could pose privacy concerns for the people involved. One way to...conference paper 2020

Cox, P.B. (author), van Rossum, W.L. (author)Recent advances in digital beam forming for phased arrays in combination with digital signal processing should enable the development of multibeam radar in a bistatic configuration. In the bistatic setting, the pulse travelling outward from the transmitter should be followed or “chased” by the receiver. During transmission, depending on the...conference paper 2020

(author)We present a study of border surveillance systems for automatic threat estimation. The surveillance systems should allow border control operators to be triggered in time so that adequate responses are possible. Examples of threats are smuggling, possibly by using small vessels, cars or drones, and threats caused by unwanted persons (e.g....conference paper 2019
