Understanding complementarity-based security proofs of quantum key distribution with imperfect sources
(Master thesis, 2017)We present a study of modern security proofs of quantum key distribution based on complementarity. This is a quantum communication protocol allowing for provable, unconditional security, although there is still a gap between ... -
Understanding crystallization in alginate-calcium phosphate composites
(Doctoral theses at NTNU;2017:18, Doctoral thesis, 2017)Summary of thesis: Tissue engineering seeks to mimic the properties and functionalities of biological tissue. In the context of bone repair, tissue engineering is becoming an increasingly important science in the active ... -
Unique photosynthetic electron transport tuning and excitation distribution in heterokont algae
(Journal article; Peer reviewed, 2019)Heterokont algae are significant contributors to marine primary productivity. These algae have a photosynthetic machinery that shares many common features with that of Viridiplantae (green algae and land plants). Here we ... -
Universal absence of Walker breakdown and linear current–velocity relation via spin–orbit torques in coupled and single domain wall motion
(Journal article, 2017)We consider theoretically domain wall motion driven by spin-orbit and spin Hall torques. We find that it is possible to achieve universal absence of Walker breakdown for all spin-orbit torques using experimentally relevant ... -
Universal Scaling Theory of the Boundary Geometric Tensor in Disordered Metals
(Peer reviewed; Journal article, 2019)We investigate the finite-size scaling of the boundary quantum geometric tensor (QGT) numerically close to the Anderson localization transition in the presence of small external magnetic fields. The QGT exhibits universal ... -
Using Background OH Airglow from astronomical Observations for atmospheric Research: A Proof of Concept
(Master thesis, 2015)The physics of the hydroxyl (OH) layer located in the Mesosphere and Lower Thermosphere (MLT) has become a focus of interest, as more and more climate models extend into this region. This is shown by the IPCC's last two ... -
Using FIB-SEM as a Platform for the Positioning and Correlated Characterization of III-V Nanowires

Utregning av det elektromagnetiske feltet i Monte Carlo transport simulering
(Master thesis, 2017)Løsning av poissons ligning under monte carlo simulering av en CdHgTe fotoskred-diode. Vi har tatt i bruk ikke-uniform mesh med adaptivt grid og gjort noen elementære simuleringer av CMT dioden. -
Utvikling og implementering av et nytt spektroskopisk ellipsometer ved bruk av liquid crystal variable retaders
(Master thesis, 2012)Denne avhandlingen tar for seg design, utvikling og bygging av et nytt forslåttMueller matrise ellipsometer (MME) ved hjelp av fire flytende krystall variable re-tardere (LCVR) som hovedkomponenter. Instrumentet har blitt ... -
UV-doser til psoriasispasienter og behandlingseffekt i løpet av tre ukers klimabehandling på Gran Canaria
(Master thesis, 2011)Psoriasis er en kronisk, inflammatorisk hudsykdom som gir tykke skjelldannelser på en rød hudoverflate. Sykdommen rammer 2-3% av den europeiske befolkningen. Ultrafiolett (UV) stråling som bruk i behandling av psoriasis ... -
Validating the algorithms AAA and Acuros for calculation of dose from flattening filter free beams in heterogenous tissue - Application to stereotactic radiotherapy of lung tumors
(Master thesis, 2015)In radiation therapy of cancer, modeling the dose to the patient is very important. Several computational algorithms are available, where some model dose in heterogeneous tissue better than others. After implementation of ... -
Validating the laminar population analysis for decomposing cortical multielectrode data on a model of the mouse primary visual cortex
(Master thesis, 2019)Teknologisk innovasjon har ført til en stor økning i mengden nevrale data som kan innhentes på en gang, noe som har avlet et behov for nye metoder for å analysere disse store, multidimensjonale datasettene. Laminære ... -
Validation of middle-atmospheric campaign-based water vapour measured by the ground-based microwave radiometer MIAWARA-C
(Journal article; Peer reviewed, 2013)Abstract. Middle atmospheric water vapour can be used as a tracer for dynamical processes. It is mainly measured by satellite instruments and ground-based microwave radiometers. Ground-based instruments capable of measuring ... -

Vapor deposited Cr-doped ZnS thin films: Towards optically pumped mid-infrared waveguide lasers
(Journal article; Peer reviewed, 2016)Compact, affordable mid-IR lasers require the development of gain materials in waveguide form. We report on the high vacuum deposition of Cr:ZnS films with concentration ranging from 1018-1020 dopants/cm3 . At low ... -
Variability of the Quasi Two-Day Wave in the Mesosphere
(Master thesis, 2013)The Quasi-Two-Day-Wave (QTDW) is examined through analysis of data given by the SKiYMET-radar at Dragvoll, Trondheim (63◦N,10◦E). Through spectral analysis the occurrence and generation mechanisms of the different wave ... -
Variation of elastic energy shows reliable signal of upcoming catastrophic failure
(Journal article; Peer reviewed, 2019)We consider the Equal-Load-Sharing Fiber Bundle Model as a model for composite materials under stress and derive elastic energy and damage energy as a function of strain. With gradual increase of stress (or strain) the ... -
