Roest, Laurien I. (author), van Heijst, S.E. (author), Maduro, L.A. (author), Rojo, Juan (author), Conesa Boj, S. (author)Exploiting the information provided by electron energy-loss spectroscopy (EELS) requires reliable access to the low-loss region where the zero-loss peak (ZLP) often overwhelms the contributions associated to inelastic scatterings off the specimen. Here we deploy machine learning techniques developed in particle physics to realise a model...journal article 2021

Fu, J. (author), Song, Guobing (author), De Schutter, B.H.K. (author)Fault location algorithms for transmission lines use the parameters of the transmission line to locate faults after the faults have occurred along the line. Although these parameters can be estimated by the phasor measurement units (PMUs) at the terminal(s) of the transmission line continuously, the uncertainty in the measurements will give...journal article 2021

Theulings, A.M.M.G. (author)The object of this thesis work was to develop a (Monte Carlo) simulation package that can be used to aid in the design of the Timed Photon Counter (TiPC). The TiPC is a single photon detector whose working principle is based upon the multiplication of an electron signal by transmission dynodes, or tynodes. For TiPC to be feasible, it is...doctoral thesis 2020

Zhao, Wenzhao (author), Wang, Hongjian (author), Gemmeke, Hartmut (author), van Dongen, K.W.A. (author), Hopp, Torsten (author), Hesser, Jürgen (author)Image reconstruction of ultrasound computed tomography based on the wave equation is able to show much more structural details than simpler ray-based image reconstruction methods. However, to invert the wave-based forward model is computationally demanding. To address this problem, we develop an efficient fully learned image reconstruction...journal article 2020

Pizzuti, Clara (author), Socievole, Annalisa (author), Prasse, B. (author), Van Mieghem, P.F.A. (author)Initially emerged in the Chinese city Wuhan and subsequently spread almost worldwide causing a pandemic, the SARS-CoV-2 virus follows reasonably well the Susceptible–Infectious–Recovered (SIR) epidemic model on contact networks in the Chinese case. In this paper, we investigate the prediction accuracy of the SIR model on networks also for...journal article 2020

Stive, M.J.F. (author), Phan, L. K. (author), Truong, S. T. (author), Phan, H. M. (author), Dao, H. T. (author)Over the last few decades, the Mekong Delta Coast has undergone many physical changes that have increased its vulnerability. Issues that have grown in importance are erosion, human occupation of coastal and estuarine mangroves, decreased sediment supply by the Mekong River and subsidence due to groundwater extraction. These issues have led to...conference paper 2020
