p-wave triggered superconductivity in single layer graphene on an electron-doped oxide superconductor
(Journal article; Peer reviewed, 2017)Electron pairing in the vast majority of superconductors follows the Bardeen–Cooper–Schrieffer theory of superconductivity, which describes the condensation of electrons into pairs with antiparallel spins in a singlet state ... -
Palladium alloy model systems forunderstanding the surface properties of Pd-based membranes and catalysts
(Doctoral Theses at NTNU, 1503-8181; 2014:9, Doctoral thesis, 2014)Palladium has high solubility, permeability and selectivity for hydrogen, thus being a suitable membrane material for hydrogen separation. In addition, palladium is a versatile catalyst with applications in industrial ... -
Parallel Instabilities in Two-Phase Flow in Porous Media
(Master thesis, 2014)Two immiscible fluids flowing in parallel with respect to the interface separating them in a two-dimensional porous medium has been studied using a dynamic network model. Two immiscible fluids, one wetting and the other ... -
Parallel integration of aligned carbon strings in polymer composite: Dielectrophoretic preparation, finite element simulation, and electrical characterization
(Journal article; Peer reviewed, 2015)We report on dielectrophoretic alignment of carbon black particles into radially arranged string-like assemblies in oligourethane mixtures followed by photopolymerization. Using finite element modelling and optical microscopy ... -
Parallel Integration of Aligned Carbon Strings in Polymer Matrix: Dielectrophoretic Preparation, Electrical and Electromechanical Characterisation
(Master thesis, 2012)Carbon black particles have been aligned into string-like assemblies by dielectrophoresis. Particles were dispersed in Dymax Ultra Light-Weld 3094 oligomermixture, with 0.1 vol.% filler content. This mixture was spread ... -
Parallelization of Coherent Point Drift for patient registration
(Master thesis, 2019)Punktskyregistrering er en sentral del i enhver anvendelse der det er ønskelig å vite hvordan to sett av punkter hører sammen, for eksempel data fra medisinske undersøkelser. Det finnes et stort utvalg av ulike algoritmer ... -
Parallell partikkeltransport implementert i Python med MPI
(Master thesis, 2017)Det er skrevet et program i Python for å beregne parallell partikkeltransport. Som numerisk integrator ble fjerdeordens Runge-Kutta-metode brukt for å beregne partikkeltransporten i et hastighetsfelt gitt ved et analytisk ... -
Paramagnetic Meissner Effect and Non-Equilibrium Vortices in Superconductor/Normal-Metal Structures
(Master thesis, 2023)Proksimitetseffekten mellom en superleder og et normalt metall fører til at noe av superledningen lekker inn i normalmetallet. Dette betyr at superledende virvler kan oppstå i normalmetallområdet. Vi studerer superleder- ... -
Parameterizations of immiscible two-phase flow in porous media
(Peer reviewed; Journal article, 2023)A fundamental variable characterizing immiscible two-phase flow in porous media is the wetting saturation, which is the ratio between the pore volume filled with wetting fluid and the total pore volume. More generally, ... -
Parametric model of the Mueller matrix of a Spectralon white reflectance standard deduced by polar decomposition techniques
(Journal article; Peer reviewed, 2013)Decomposition methods have been applied to in-plane Mueller matrix ellipsometric scattering data of the Spectralon reflectance standard. Data were measured at the wavelengths 532 nm and 1500 nm, using an achromatic optimal ... -
Parametrisering av Kraftfelt for ReaxFF
(Master thesis, 2008)Denne oppgaven tar for seg innsamling av data for optimerte geometrier, energier og ladninger for molekylstrukturer av aluminium, indium (gruppe 3-atomer) og arsen (gruppe 5-atom), samt hydrogen. All informasjon er samlet ... -
Parametrisering av kraftfelt for ReaxFF med H, C, Si og Ge
(Master thesis, 2008)Sammenligning av DFT og ReaxFF beregninger for å kunne validere gjorte beregninger som input til paramtreisering av kraftfelt i ReaXFF for C, Si og Ge. -
Partial Discharges on an Epoxy Surface due to Water Droplets
(Master thesis, 2011)Offshore wind turbines are exposed to a very harsh environment and can sustain significant damage during operation. In this thesis work, the possibilities of partial discharges in an insulation system of an offshore wind ... -
Particle Assembly Guided by Electrohydrodynamics and Dielectrophoresis
(Doctoral thesis at NTNU;2016:121, Doctoral thesis, 2016)Norwegian: Vanlige utfordringer i forbindelse med oljeutvinning og produksjon av blant annet mat, medisin og kosmetikkprodukter er å hindre at dråper vokser sammen. Prøver man å blande to ikke-blandbare væsker (som ... -
Particle creation in vacuum states using quantum field theory
(Master thesis, 2021)I denne masteravhandlingen introduserer vi en kvantisert felt-teori. Det kvantiserte feltet brukes til å vise at partikler blir skapt i tilstander som opprinnelig er vakum-tilstander, som betyr at det er ingen partikler ... -
Particle Production in Gravitational Fields
