Alloy structure of rare earth Ce with Pt base metal, and the adsorption of CO
Nigussa, Kenate Nemera; Støvneng, Jon Andreas (Peer reviewed; Journal article, 2019)The alloy structure of Ce and Pt inter-metallics is investigated with density functional theory. A systematic analysis of different alloy structures and surface terminations, as well as adsorption of CO in different sites ... -
An acoustical study of trombone performance, with special attention to auditory feedback deprivation
Kristensen, Eirik (Master thesis, 2014)When discussing how instruments work and how performers play them, the matter can be viewed from the standpoint of the musician or the scientist. In an attempt to bridge the gap between what science and musical experience ... -
Analysis of The Norwegian Veterinary Institute's Model for Salmon Lice Abundance Prediction
Bogen, Johannes (Master thesis, 2018)Empirical studies have found that lice from salmon farms are a main source of infection of wild salmonids. Due to Norway s responsibility to conserve wild stocks of salmon, Veterinærinstituttet has created a statistical ... -
Application of the Linear Eddy Model - A Study of Differential Diffusion in Turbulent Hydrogen-Rich Jets
Bjørdalsbakke, Nikolai Lid (Master thesis, 2018)Differential diffusion effects in turbulent reactive and non-reactive problems based on hydrogen-rich fuels are not yet fully investigated. Through use of a Fortran implementa-tion of the Linear Eddy Model (LEM) ... -
Automatic Detection of Air Emboli in The Cerebral Circulation in Newborns By Ultrasound Doppler Technique
Lam, My Tam (Master thesis, 2022)Når spedbarn er født med hjertesvikt eller en annen form for defekt i hjertet kan det være nødvendig med kateterintervensjon eller hjertekirurgi. Slike inngrep kan føre til at luftbobler blir introdusert inn i blodstrømmen. ... -
Calculation of Terminal Currents in Single Photon Excited Avalanche Photodiodes.
Vestby, Aksel Jan Verne (Master thesis, 2012)We use the Shockley-Ramo (SR) theorem to calculate terminal currents in single photon excited APDs. A unified notation for the SR theorem is introduced, and we derive the theorem in those particular ways found useful for ... -
Calculation of Wavefunction Overlaps in First Principles Electronic Structure Codes
