(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)This study investigates the use of covariant Lyapunov vectors and their respective angles for detecting transitions between metastable states in dynamical systems, as recently discussed in several atmospheric sciences ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2020)The structure and performance of neural networks are intimately connected, and by use of evolutionary algorithms, neural network structures optimally adapted to a given task can be explored. Guiding such neuroevolution ...
-
(Master thesis / Masteroppgave, 2019)Transform faults are strike-slip faults that accommodate lateral offsets between spreading segments of mid-ocean ridges. Because plates cannot move perpendicular to them, transform faults may exert a control on plate motions ...
