Drag and Phases in Interacting and Spin-Orbit Coupled Superfluid Bose-Einstein Condensates
(Master thesis, 2018)Motivated by previous work on drag effects in superfluid Bose-Einstein condensates, the Bose-Hubbard model on the square lattice is considered using mean-field theory, and a method for computing the superfluid drag density ... -
Drivers of the high frequency variability of gravity wave forcing in the mesosphere and lower thermosphere
(Master thesis, 2015)In this thesis the influence of gravity waves (GWs) in the mesosphere/lower thermosphere (MLT) was analysed. This was inspired by the work done in the paper by de Wit et al. (2014), which used the SKiYMET meteor radar in ... -
Drop-on-demand i presisjonsjordbruk
(Master thesis, 2013)Denne oppgaven beskriver et eksperiment der vi har skutt dråper gjennom luft med hastighet 4 m/s pluss/minus 10%. Hensikten var å skyte dråper så langt som mulig med definert presisjon og uten oppbrytning ved å justere 3 ... -
DScribe: Library of descriptors for machine learning in materials science
(Journal article; Peer reviewed, 2019)DScribe is a software package for machine learning that provides popular feature transformations (“descriptors”) for atomistic materials simulations. DScribe accelerates the application of machine learning for atomistic ... -
Dynamic contrast-enhanced MRI in head and neck cancer: a systematic comparison of different modelling approaches
(Master thesis, 2022)Bakgrunn Kreftsvulster er karakterisert av uorganisert blodkarnettverk på grunn av økt angiogenese, som vil si formasjon av blodårer. Dette resulterer i at svulsten får områder med lavt oksygennivå, kalt hypoksi. Hypoksi ... -

Dynamic Light Scattering Based Microrheology of End-Functionalised Triblock Copolymer Solutions
(Peer reviewed; Journal article, 2023)Nano-sized particles functionalised with short single-stranded (ss)DNAs can act as detectors of complementary DNA strands. Here we consider tri-block-copolymer-based, self-assembling DNA-coated nanoparticles. The copolymers ... -
Dynamic Micro-CT utilising Golden Ratio Sampling and Three-dimensional Generative Adversarial Networks
(Master thesis, 2023)Temporal datatomografi, dynamisk datatomografi, eller bare 4D-CT, er en røntgenavbildningsteknikk hvor tredimensjonale dynamiske prosesser kan avbildes. Ulempen med CT er de mange projeksjonene som kreves for å rekonstruere ... -
Dynamic Pore Network Study of Immiscible Two-Phase Flow in Porous Media
(Doctoral theses at NTNU;2023:332, Doctoral thesis, 2023)Porous media research has widespread applications in a variety of fields including biology, medicine, and geology. Notably, it can be used to mitigate the effects of climate change through methods of carbon capture and ... -
Dynamic renormalization group of interfaces in scalar active matter
(Master thesis, 2022)Biologiske systemer er ofte bygget opp av partikler som er kapable til å transformere kjemisk energy som er lagret i systemet til arbeid eller felles bevegelse. Slike systemer kalles aktive systemer og kan eksemplifiseres ... -
Dynamic Wettability Alteration in Immiscible Two-phase Flow in Porous Media: Effect on Transport Properties and Critical Slowing Down
(Journal article; Peer reviewed, 2015)The change in contact angles due to the injection of low salinity water or any other wettability altering agent in an oil-rich porous medium is modeled by a network of disordered pores transporting two immiscible fluids. ... -
Dynamical Simulation of Causal Sets
(Master thesis, 2016)Two different dynamical schemes for production of physically meaningful causal sets are described and explored through the use of original computer simulations made using C++. Both of the schemes are found inappropriate ... -
Dynamical tuning between nearly perfect reflection, absorption, and transmission of light via graphene/dielectric structures
(Journal article; Peer reviewed, 2016)Exerting well-defined control over the reflection (R), absorption (A), and transmission (T) of electromagnetic waves is a key objective in quantum optics. To this end, one often utilizes hybrid structures comprised of ... -
Dynamical-Chemical Coupling in the Polar Middle Atmosphere: Effects of Energetic Particle Precipitation on the Middle Mesospheric Maximum
(Master thesis, 2019)Det midtre mesosfæriske ozonmaksimum er et nylig oppdaget fenomen, som finner sted i atmosfæren over polområdene vinterstid. Geomagnetisk aktivitet er kjent for å spille en viktig rolle i den midtre atmosfærens ozonbudsjett, ... -
