Continuous Evolution of Digital Twins using the DarTwin Notation

Autor: Mertens, Joost, Klikovits, Stefan, Bordeleau, Francis, Denil, Joachim, Haugen, Øystein

Despite best efforts, various challenges remain in the creation and maintenance processes of digital twins (DTs). One of those primary challenges is the constant, continuous and omnipresent evolution of systems, their user's needs and their environme

Autor: Nipen, Thomas Nils, Haugen, Håvard Homleid, Ingstad, Magnus Sikora, Nordhagen, Even Marius, Salihi, Aram Farhad Shafiq, Tedesco, Paulina, Seierstad, Ivar Ambjørn, Kristiansen, Jørn, Lang, Simon, Alexe, Mihai, Dramsch, Jesper, Raoult, Baudouin, Mertes, Gert, Chantry, Matthew

A data-driven model (DDM) suitable for regional weather forecasting applications is presented. The model extends the Artificial Intelligence Forecasting System by introducing a stretched-grid architecture that dedicates higher resolution over a regio

Comments on the publication 'Discrete symmetries tested at 10e-4 precision using linear polarization of photons from positronium annihilations' by P. Moskal et al

Autor: George, E. A., Haugen, T. E., Naviliat-Cuncic, O., Voytas, P. A.

The authors of Ref.[1] (referred to here as "Moskal et al.") claim to have performed the most precise test of P, T and CP invariance in the decay of ortho-Positronium. In this note: 1) we demonstrate, assuming standard properties for Compton scatteri
