Auroral oval morphology: Dawn-dusk asymmetry partially induced by Earth’s rotation
(Journal article; Peer reviewed, 2023)The auroral oval morphology has been investigated in previous studies presenting maps of average auroral precipitation. However, such distributions tend to emphasize auroral intensity rather than the actual extent of the ... -
Auroral Region Morphology and the Influence of Earth’s Rotation on Geospace Dynamics
(Doctoral thesis, 2024-06-07)Koblingen mellom solvinden, magnetosfæren, og ionosfæren er avgjørende for å forstå verdensrommet og dens påvirkning på Jorden. I de øvre lagene av atmosfæren ved polene, spesielt i området kjent som auroraregionen, møtes ... -
Automated XY-table for the characterisation of arrays of pixel sensors for photons and charge particles
(Master thesis, 2010-06-01)A variety of arrays of pixels sensors (pixel = picture elements) have been developed during the last 30 years for the detection of photons and charge particles. Pixel based semiconductor detectors are not only used for ... -
Autonomic Operation of a Large High Performance On-Line Compute Cluster
(Doctoral thesis, 2015-12-10)A High-Level Trigger (HLT) system is composed of both hardware and software. Designing the physical layout of the cluster mainly concerns the hardware; node distribution, network layout, estimation of power requirements, ... -
