Diffusive Curved Superconductor-Ferromagnet Proximity Systems in and out of Equilibrium
(Master thesis, 2022)I strukturer med superledere og ferromagneter kan superledende korrelasjoner lekke et lite stykke inn i ferromagneten; dette er den superledende proksimitetseffekten. Hybridsystemer hvor denne effekten er signifikant kan ... -
Diffusjon av vann i sotfylte kappematerialer for polymere sjøkabler
(Master thesis, 2011)Vanntrevekst er den viktigste årsaken til aldring i polymerisk isolasjon i mellomspenningskabler. Sia vanntrær ikke dannes ved lav relativ fuktighet (R.H.), er det viktig å holde relativ fuktighet i isolasjonen lav så lenge ... -
Digital threshold markers of atypical sheep movement on rangeland pastures by the use of the machine learning models k-means and DBSCAN
(Master thesis, 2022)Determining the data driven description of the behaviour in sheep on rangeland grazing pastures is in demand to ensure welfare and sustainability in both Norwegian and worldwide modern pastoral systems. This study investigated ... -
Dimensional reduction of the Two-Higgs Doublet Model with a softly broken Z2 symmetry at one-loop
(Master thesis, 2017)In the collaboration between NTNU, the University of Stavanger, and the University of Helsinki we pursue a satisfactory answer to the problem of baryogenesis, i.e. the origin of the asymmetry in the amount of baryons and ... -

Dipolar ordering of clay particles in various carrier fluids
(Journal article; Peer reviewed, 2012)We investigate here examples of complexity in composite materials. The objective of the paper is to show that clay particles can be aligned in different hosting media, such as: silicone oil, paraffin-wax, polystyrene and ... -
Direct and inverse superspin Hall effect in two-dimensional systems: Electrical detection of spin supercurrents
(Journal article; Peer reviewed, 2019)A useful experimental signature of the ordinary spin Hall effect is the spin accumulation it produces at the sample edges. The superspin Hall current [Phys. Rev. B 96, 094512 (2017)] is a transverse equilibrium spin current ... -
Direct Determination of Chitosan–Mucin Interactions Using a Single-Molecule Strategy: Comparison to Alginate–Mucin Interactions
(Journal article; Peer reviewed, 2015)Aqueous chitosan possesses attractive interaction capacities with various molecular groups that can be involved in hydrogen bonds and electrostatic and hydrophobic interactions. In the present paper, we report on the direct ... -
Directionality and column arrangement principles of precipitates in Al-Mg-Si-(Cu) and Al-Mg-Cu linked to line defect in Al
(Journal article, 2016)In the structures of all metastable precipitates in Al-Mg-Cu and Al-Mg-Si alloys, we find that column surrounding of an element column in the needle/lath direction order according to simple principles. Advanced transmission ... -
Discrimination of Breast Cancer from Healthy Breast Tissue Using a Three-component Diffusion-weighted MRI Model
(Peer reviewed; Journal article, 2020)Purpose: Diffusion-weighted MRI (DW-MRI) is a contrast-free modality that has demonstrated ability to discriminate between predefined benign and malignant breast lesions. However, how well DW-MRI discriminates cancer from ... -
Discrimination of Malignant and Non-Malignant Urinary Bladder Cells Using Microfluidic Constriction Deformation Cytometry
(Master thesis, 2023)Kreft er en av de ledende dødsårsakene på verdensbasis og forårsaket en av seks dødsfall i 2020. For å redusere dødeligheten er screening og tidlig diagnose avgjørende. Studier gjort på forskjellige krefttyper, viser at ... -
Disentangling electron-boson interactions on the surface of a familiar ferromagnet
(Peer reviewed; Journal article, 2024)We report energy renormalizations from electron-phonon and electron-magnon interactions in spin minority surface resonances on Ni(111). The different interactions are identified, disentangled, and quantified from the ... -
Dislocation dynamics study of precipitate hardening in Al-Mg-Si alloys with input from experimental characterization
(Journal article; Peer reviewed, 2017)Partial aging of AA6060 aluminum alloys is known to result in a microstructure characterized by needle-shaped Si/Mg-rich precipitates. These precipitates belong to the non-equilibrium β″ phase and are coherent with the ... -
Disorder-induced non-linear growth of fingers in immiscible two-phase flow in porous media
(Journal article; Peer reviewed, 2024)Immiscible two-phase flow in porous media produces different types of patterns depending on the capillary number Ca and viscosity ratio M. At high Ca, viscous instability of the fluid–fluid interface occurs when the displaced ... -
Dispersion hardening during annealing at low Temperatures in four 3xxx Al-Mn-Fe-Si Alloys
(Master thesis, 2012)3xxx aluminiumslegeringer har Mangan som hovedlegeringselement, og får sin styrke fra plastisk bearbeidelse. 3xxx legeringer har tidligere blitt ansett for å oppnå neglisjerbare endringer i hardhet og styrke som følge av ... -
Dispersion Measurement of Infrared Specialty Fibers
