van den Berg, Jan (author)For most people, cybersecurity is a hard to grasp notion. Traditionally, cybersecurity has been considered as a technical challenge and still many specialists view it equivalent with information security, with the notions of confidentiality, integrity and availability as starting points of thinking. And although others searched for a broader...conference paper 2019

Leijsen, R.L. (author), van den Berg, Cornelis (author), Webb, A. (author), Remis, R.F. (author), Mandija, Stefano (author)Magnetic resonance electrical properties tomography (MR-EPT) is a technique used to estimate the conductivity and permittivity of tissues from MR measurements of the transmit magnetic field. Different reconstruction methods are available; however, all these methods present several limitations, which hamper the clinical applicability. Standard...journal article 2019

(author), van den Berg, Cornelis A.T. (author), Raaijmakers, Alexander J. E. (author)Purpose: Patients who have medical metallic implants, e.g. orthopaedic implants and pacemakers, often cannot undergo an MRI exam. One of the largest risks is tissue heating due to the radio frequency (RF) fields. The RF safety assessment of implants is computationally demanding. This is due to the large dimensions of the transmit coil...journal article 2019

Maathuis, E.C. (author), Pieters, W. (author), van den Berg, Jan (author)Cyber operations lack models, methodologies, and mechanisms to describe relevant data and knowledge. This problem is directly reflected when cyber operations are conducted and their effects assessed, and it can produce dissonance and disturbance in corresponding decision-making processes and communication between different military actors.

van Driel, B.A. (author), van den Berg, K.J. (author), Gerretzen, J. (author), Dik, J. (author)White pigments were abundantly used in 20th century paintings, and relate to several degradation risks such as titanium white mediated photocatalytic binder degradation or zinc soap formation. Knowledge about the white pigments that were used is essential for risk assessments of 20th century collections. In this study, a representative set of...journal article 2018

van Driel, B.A. (author), van der Meer, Sharon R. (author), van den Berg, K.J. (author), Dik, J. (author)Twentieth century paints often contain titanium dioxide and zinc oxide based white pigments that can range from photostable to highly photocatalytic. Photocatalytic pigments can cause the degradation of paint upon UV exposure, whereas photostable pigments may be benign or can protect paintings from degradation. Hence, knowing whether or not a...journal article 2018

van den Boomen, M. (author), van den Berg, P.L. (author), Wolfert, A.R.M. (author)In the next decades, many public infrastructure assets will reach the end of their life that they were originally designed for. Replacement costs are high, and therefore increasing effort is put into lifetime-extending maintenance, including major overhauls and renovations. A key question is whether the investments in lifetime-extending...journal article 2018
