Film flow dominated simultaneous flow of two viscous incompressible fluids through a porous medium
(Journal article; Peer reviewed, 2014-11-19)We present an experimental study of two-phase flow in a quasi-two-dimensional porous medium. The two phases, a water-glycerol solution and a commercial food grade rapeseed/canola oil, having an oil to water-glycerol viscosity ... -
Finding performance parameters and implementing bulk corrections for SEM EDS data in open-source software
(Master thesis, 2023)Målet med dette arbeidet er å forbedre analysen av data fra energidispersiv røntgenspektroskopi i skanneelektronmikroskop (SEM EDS) gjennom (1) måling av ytelsesparametere og (2) bulkkorrigeringer for kvalitativ analyse i ... -
Fine material processing using ultra-short pulsed 2 μm all-fiber lasers
(Doctoral theses at NTNU;2022:327, Doctoral thesis, 2022)Precision processing of silicon (Si) and other semiconductors is becoming increasingly important following the rising demand for semiconductor-based devices. Laser-assisted material processing on and below the surface can ... -
Fingerprints of Universal Spin-Stiffness Jump in Two-Dimensional Ferromagnets
(Peer reviewed; Journal article, 2020)Motivated by recent progress on synthesizing two-dimensional magnetic van der Waals systems, we propose a setup for detecting the topological Berezinskii-Kosterlitz-Thouless phase transition in spintransport experiments ... -
Finite Element Modeling of Heat Generation in 1-3 Piezocomposite Transducers for Underwater Ultrasonic Applications
