Reconfigurable Mechanical Anisotropy in Self-Assembled Magnetic Superstructures
(Peer reviewed; Journal article, 2021)Enhancement of mechanical properties in self-assembled superstructures of magnetic nanoparticles is a new emerging aspect of their remarkable collective behavior. However, how magnetic interactions modulate mechanical ... -
Reconstructing surface morphology using coherent X-ray diffraction combined with iterative phase retrieval algorithms
(Master thesis, 2019)Inversjon av spredningsdata er et omfattende problem i røntgenfysikk og gir opphav til faseproblemet. I spredningseksperimenter blir bare intensiteten målt, mens faseinformasjonen er tapt. Rekonstruering av spredningsobjektet ... -
Reconstruction of Images From a Compact Spectral Camera
(Master thesis, 2011)Hyperspectral imaging provides a lot of information about the imaged scene, and has several applications. The purpose of this work is to reconstruct hyperspectral images from pictures captured with a compact hyperspectral ... -
Recovering fluorophore concentration profiles from confocal images near lateral refractive index step changes
(Peer reviewed; Journal article, 2016)Optical aberrations due to refractive index mismatches occur in various types of microscopy due to refractive differences between the sample and the immersion fluid or within the sample. We study the effects of lateral ... -
Recrystallization of silicon core fibers by CO2 laser annealing
(Master thesis, 2017)The innovation of introducing silicon in the core of optical glass fibers has lately been of great interest to the optoelectronics industry. The application areas of silicon core fibers are ranging from medical imaging and ... -
Red versus blue light illumination in hexyl 5-aminolevulinate photodynamic therapy: the influence of light color and irradiance on the treatment outcome in vitro
(Journal article; Peer reviewed, 2014)Abstract. Hexyl 5-aminolevulinate (HAL) is a lipophilic derivative of 5-aminolevulinate, a key intermediate in biosynthesis of the photosensitizer protoporphyrin IX (PpIX). The photodynamic efficacy and cell death mode ... -

Refinement of the ζ-factor Method for Quantitative Energy-Dispersive X-ray Spectroscopy in Scanning Transmission Electron Microscopy
(Master thesis, 2016)The ζ-factor method for quantitative energy-dispersive X-ray spectroscopy (EDS) has been implemented using the open source Python-based HyperSpy library. The ζ-factors for Ga, As, Al, C and Sb have been determined ... -
Reflection of diffuse light from two-dimensional rough surfaces & The light scattering properties of Gaussian-cosine correlated surfaces
(Master thesis, 2021)I denne oppgaven studeres reflektansen til 2D tilfeldig rue overflater opplyst av diffust lys, sammen med sprednings- og de polarimetriske egenskaper til Gaussisk-cosinus korrelerte overflater, gjennom resultater oppnådd ... -
Reheating constraints on modified single-field natural inflation models
(Peer reviewed; Journal article, 2022)In this paper, we discuss three modified singlefield natural inflation models in detail, including Special generalized natural inflation model (SNI), extended natural inflation model (ENI) and natural inflation inspired ... -
Relationship between Al-Ni intermetallic Phases and Bond Strength in Roll Bonded Steel-Aluminum Composites with Nickel Interlayers
(Journal article; Peer reviewed, 2019)In this work, the interface characteristics and resulting bond strength were investigated for roll bonded steel-aluminum composites with nickel interlayers, both after rolling and after post-rolling heat treatments at 400 ... -
Relativistic Fermions in Graphene
(Master thesis, 2012)The Fermi surface of graphene contains points where the connection between excitation energy and crystal momentum is linear, similar to massless or ultrarelativistic fermions. This is important for the physical properties ... -
Relaxation process of Yukawa glassy system
(Master thesis, 2022)Relaksasjonsprosessen til et glass-system er av høy interesse i mange industrier, blant annet farmasi, kosmetikk, mat og bygge bransjen. Når et glass formes øker som regel viskositeten og dynamikken til systemet blir mye ... -
ReleQuant - improving teaching and learning in quantum physics through educational design research
(Journal article; Peer reviewed, 2015)Quantum physics and relativity are demanding for teachers and students, but have the potential for students to experience physics as fascinating and meaningful. Project ReleQuant engaged in educational design research to ... -
Reliability of resting-state functional connectivity in the human spinal cord: Assessing the impact of distinct noise sources
(Peer reviewed; Journal article, 2023)The investigation of spontaneous fluctuations of the blood-oxygen-level-dependent (BOLD) signal has recently been extended from the brain to the spinal cord, where it has stimulated interest from a clinical perspective. A ... -
The reliability of wind power in the Longyearbyen area
(Research report, 2021)Within this decade the current energy system in Longyearbyen has to be revolutionised. Right now, it relies entirely on fossil fuels, but in the future it is envisioned to be a front-runner of renewable systems in the ... -
Renewable CO2 recycling and synthetic fuel production in a marine environment
(Peer reviewed; Journal article, 2019)Humankind must cease CO2 emissions from fossil fuel burning if dangerous climate change is to be avoided. However, liquid carbon-based energy carriers are often without practical alternatives for vital mobility applications. ... -
Renormalised Intrinsic and Extrinsic Impurity Induced Spin-orbit Scattering in Graphene
(Master thesis, 2012)We study the effect of an impurity potential on spin-memory loss in graphene. Various general methods for finding the spin-orbit related effect of a slowly varying impurity potential on a semiconductor have been examined. ... -
Replacement of Ensemble Averaging by the Use of a Broadband Source in Scattering of Light from a One-Dimensional Randomly Rough Interface between Two Dielectric Media
(Journal article; Peer reviewed, 2018)By the use of phase perturbation theory we show that if a single realization of a one-dimensional randomly rough interface between two dielectric media is illuminated at normal incidence from either medium by a broadband ... -
