Equations of motion and frequency dependence of magnon-induced domain wall motion
(Journal article; Peer reviewed, 2017)Spin waves can induce domain wall motion in ferromagnets. We derive the equations of motion for a transverse domain wall driven by spin waves. Our calculations show that the magnonic spin-transfer torque does not cause ... -
Equilibrium Climate after Spectral and Bolometric Irradiance Reduction in Grand Solar Minimum Simulations
(Peer reviewed; Journal article, 2023)In this study, we use the Whole Atmosphere Community Climate Model, forced by present-day atmospheric composition and coupled to a Slab Ocean Model, to simulate the state of the climate under grand solar minimum forcing ... -
Equipment and Production of Columnar Sea Ice Replica in NTNU Cold Lab
(Master thesis, 2014)This Master's thesis considers an ice tank used for production of ice in a cold lab at NTNU. The goal was to improve the temperature control of the water in the tank. Original sensors were replaced with seven new sensors ... -
Er,Yb:GdAl3(BO3)4 laser passively Q-switched by MBE-grown Cr:ZnS thin films
(Chapter; Peer reviewed, 2017) -
Escape model for Galactic cosmic rays
(Peer reviewed; Journal article, 2016)We show that the cosmic ray (CR) knee can be entirely explained by energy-dependent CR leak-age from the Milky Way, with an excellent fit to all existing data. We test this hypothesis cal-culating the trajectories of ... -
The Establishment of an Intravoxel Incoherent Motion Based MRI-Protocol for Differentiation of Focal Lesions in the Pancreas
(Master thesis, 2015)The mortality related to pancreatic cancer is high. It spreads rapidly and as the situation is today it is often not diagnosed until a quite late stage. However, recent studies have shown that the intravoxel incoherent ... -
Estimating and Reporting Uncertainties in Remotely Sensed Atmospheric Composition and Temperature
(Peer reviewed; Journal article, 2020)Remote sensing of atmospheric state variables typically relies on the inverse solution of the radiative transfer equation. An adequately characterized retrieval provides information on the uncertainties of the estimated ... -
Estimating stratospheric polar vortex strength using ambient ocean-generated infrasound and stochastics-based machine learning
(Journal article; Peer reviewed, 2024)There are sparse opportunities for direct measurement of upper stratospheric winds, yet improving their representation in subseasonal-to-seasonal prediction models can have significant benefits. There is solid evidence ... -
Estimation of Design Snow Loads on Offshore Structures in the Barents Sea
(Master thesis, 2016)Snow accumulating on offshore structures can reduce freeboard and stability, block equipment and valves, and reduce operability of the platform or ship. It is thus important to evaluate snow conditions before starting long ... -
Estimation of nonlinear bulk elasticity parameter for cancer tumors
(Master thesis, 2021)Tofrekvens-ultralyd har blitt brukt til å estimere ikke-lineær bulk elastisitet for adenokarsinom i bukspyttkjertelen (PDAC svulst), den vanligste krefttypen i bukspyttkjertelen. Svulstene har vokst i KPC-mus, men målingene ... -
Estimation of Skin Optical Parameters for Real-Time Hyperspectral Imaging Applications using GPGPU Parallel Computing
(Master thesis, 2013)Hyperspectral imaging with a high spatial and spectral resolution can be used to analyze materials using spectroscopic methods. This can be applied on skin as a general purpose real-time diagnostic tool.Light transport ... -
Et katapultprosjekt: hva kan det bidra med i fysikkfaget?
(Master thesis, 2008)Denne oppgaven tar for seg et undervisningsopplegg laget for å teste ut hvordan et katapultprosjekt kan bidra til elevers kunnskaper, ferdigheter og motivasjon i fysikkfaget. Norske elever har gjort det jevnt over dårligere ... -
Et kritisk og konstruktivt blikk på naturfaget i norsk skole

Evaluating template matching for orientation analysis based on electron diffraction
(Master thesis, 2020)For å relatere strukturelle trekk ved et materiale til dets eganskaper er fase- og orientasjonskart mye brukt, for å få informasjon om fordelingen av korn, krystallografisk tekstur og mulige sammenhenger mellom orientasjoner. ... -
Evaluation of Acousto-Optic Tunable Filter for Wavelength Dependent Measurements of Waveguides
(Master thesis, 2017)The main part of the work done for this master's thesis have been to implement and characterize a setup that would allow for wavelength dependent measurements of losses in waveguides. A plasma enhanced white light source ... -
Evaluation of ORR active sites in nitrogen-doped carbon nanofibers by KOH post treatment
(Journal article; Peer reviewed, 2018)Oxygen reduction on N-doped carbon nanomaterials is believed to take place at either N-centered active sites (C-Nx) or Fe-centered active sites (Fe-Nx). In this work the origin of the oxygen reduction on nitrogen-doped ... -
Evaluation of Reoxidation Thresholds for γ-Al2O3-Supported Cobalt Catalysts under Fischer - Tropsch Synthesis Conditions
(Journal article; Peer reviewed, 2017)Size-dependent phenomena at the nanoscale influence many applications, notably in the science of heterogeneous catalysis. In cobalt-based Fischer–Tropsch synthesis (FTS), the size of Co nanoparticles (NPs) dictates to a ... -
