(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

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

Bruin-Hoegee, J.M. (author), Kleiweg, D. (author), Noort, D. (author), van Asten, A.C. (author)Chemical attribution typically aims to establish a link between material found at a crime scene and a person, location or other evidence. In the field of illicit drugs, chemical attribution signatures are usually impurity profiles. Extending these to metabolized samples would create new possibilities in forensic investigations. The present study...article 2021

(author), Yevdokimov, A. (author), Schoenmakers, P. (author), Smith, J. (author), Oxley, J. (author), van Asten, A. (author)Erythritol tetranitrate (ETN) was prepared independently by two research groups from the USA and the Netherlands. The partially nitrated impurities present in ETN were studied using liquid chromatography-mass spectrometry to address the ultimate challenge in forensic explosives investigations, i.e., providing chemical and tactical information on...article 2020

Witte, J.P.M. (author), Zaadnoordijk, W.J. (author), Buyse, J.J. (author)Since the nineteen fifties, groundwater levels in the Netherlands dropped more than as simulated by hydrological models. In the rural sandy part of the Netherlands, the difference amounts to approximately 0.3 m on average. The answer to the question of what or who caused this 'background decline' of groundwater tables may have juridical and...article 2019

Verolme, E.K. (author), van der Voort, M.M. (author), Smits, R. (author), Weerheijm, J. (author), Koh, Y.H. (author), Kang, K.W. (author)There is limited knowledge on deriving the strength of an explosion based on the observed explosion effects. Existing methods are based primarily on the effects of blast overpressure on surrounding structures. Window breakage and structural damage are well studied and are widely used to derive most probable explosion strengths. Other explosive...article 2018

(author)Studying links between triacetone triperoxide (TATP) samples from crime scenes and suspects can assist in criminal investigations. Isotope ratio mass spectrometry (IRMS) and gas chromatography (GC)-IRMS were used to measure the isotopic compositions of TATP and its precursors acetone and hydrogen peroxide.

Bortolameotti, R. (author), Peter, A. (author), Everts, M.H. (author), Jonker, W. (author), Hartel, P. (author)We address the problem of determining what data has been leaked from a system after its recovery from a successful attack. This is a forensic process which is relevant to give a better understanding of the impact of a data breach, but more importantly it is becoming mandatory according to the recent developments of data breach notification laws....conference paper 2016
