Fourier ptychography for computationally enhanced imaging in two and three dimensions
(Master thesis, 2019)Fourierptykografi (FP) er en nylig utviklet beregningsbasert avbildningsteknikk som kan forbedre egenskapene til et konvensjonelt optisk mikroskop utover de klassiske grensene som bestemmes av de optiske komponentene ... -
Fracture networks in sea ice
(Journal article; Peer reviewed, 2014-04-16)Fracturing and refreezing of sea ice in the Kara sea are investigated using complex network analysis. By going to the dual network, where the fractures are nodes and their intersections links, we gain access to topological ... -
Fracturing of Optimal Paths in a Random Lattice
(Master thesis, 2011)The subject of this thesis is the study of the creation of fault lines in a random lattice, provoked by the successive failure of optimal paths. Using the recently developed Optimal Path Cracked model, we investigate how ... -
Fresnel imaging of ferromagnetic domain wall motion using fast pixelated electron detector
(Master thesis, 2022)Magnetic imaging techniques are of great importance for the further development of magnetic materials to be used in promising applications for information storage and sensory devices. The main aim of this thesis was to ... -
Friction Models for Oscillating Flow in a U-tube
(Master thesis, 2014)The basic theory of friction in pipe flow was reviewed in the first part of this thesis. Using the results from this review, steady state friction relations were derived for laminar and turbulent pipe flow.Steady state ... -
From Building to Bildung Engineering Students’ Motivation Towards Interacting with Society
(Journal article, 2020)In this study 567 engineering students are asked about their motivation for becoming engineers, and what non-technical topics engineers should know about. The study is conducted in connection with teaching the course ... -
From multisource data to clinical decision aids in radiation oncology: The need for a clinical data science community
(Journal article; Peer reviewed, 2020)Big data are no longer an obstacle; now, by using artificial intelligence (AI), previously undiscovered knowledge can be found in massive data collections. The radiation oncology clinic daily produces a large amount of ... -
From Nucleation to Percolation: The Effect of System Size when Disorder and Stress Localization Compete
(Peer reviewed; Journal article, 2021)A phase diagram for a one-dimensional fiber bundle model is constructed with a continuous variation in two parameters guiding the dynamics of the model: strength of disorder and range of stress relaxation. When the range ... -
From Rock Scissor Paper to study and modeling of Chinese Five Elements: Evolutionary Game Theory
(Master thesis, 2013)In this thesis, we have developed a model to study the behavior of an extended version of evolutionary game "Rock-Scissor-Paper", that is "Five Elements". The origin of five elements are from "Chinese five elements" in ... -
Full Waveform Inversion of Gas Hydrates: Application to estimate of hydrate saturation
(Master thesis, 2014)Through seismic acquisitions there have been discovered layers beneath the seabedthat consist of pores filled with gas hydrates (GH). These reservoirs are potentialenergy reserves and it is therefore desirable to get an ... -
Fully resolved strain field of the β’’ precipitate calculated by density functional theory
(Peer reviewed; Journal article, 2020)The β′′ precipitate is the main hardening phase in age hardenable Al-Mg-Si alloys, and it is therefore of major scientific and industrial importance. A full model of the β′′ precipitate cross-section embedded in an aluminium ... -
Fundamental formulae for wave-energy conversion
(Journal article; Peer reviewed, 2015)The time-average wave power that is absorbed, from an incident wave, by means of a wave energy conversion (WEC) unit, or by an array of WEC units--i.e. oscillating immersed bodies and/or OWCs--may be mathematically expressed ... -
Fundamental Theories and Methodologies for Assessing Radiation Hardness in Hydrogen-Terminated Diamond
(Master thesis, 2018)The origin of conductivity in hydrogen terminated diamond, and the effect of MoO3 deposition is explained. Further, the various effects that can be induced upon particle irradiation and the mechanisms behind them is ... -
Gamma-ray counterpart of the IceCube neutrinos
(Journal article; Peer reviewed, 2019)A γ-ray excess at high Galactic latitudes starting at energies 300 GeV was recently discovered in the data of the Fermi telescope. The multi-TeV γ-ray emission found has spectral characteristics at both low and high Galactic ... -
Gamma-ray counterparts of 2WHSP high-synchrotron-peaked BL Lac objects as possible signatures of ultra-high-energy cosmic ray emission
