''Den figuren er irrelevant for meg'': En kvalitativ studie om elevers bruk av bilder og figurer i lærebøker i fysikk
(Master thesis, 2013)Oppgaven undersøker hvordan elever bruker metaforer, analogier og bilder i lærebøker i fysikk i egne læringsprosseser. Studien er bygd opp med intervju som datainnsamlingsmetode. Utvalget består av totalt åtte elever som ... -
Interface energy determination for the fully coherent β'' phase in Al-Mg-Si: making a case for a first principles based hybrid atomistic modelling scheme
(Journal article, 2013)Multiscale modelling of hardening precipitate interfaces in alloy design This project will develop a new multiscale modelling scheme used to investigate hardening precipitate interfaces in metal alloys. The major aim is ... -
Solar and Lunar Tides in the MLT
(Master thesis, 2013)Simulations were done in Matlab to see how many days of data is needed to get accurate values of solar and lunar semidiurnal tides amplitudes and phases. For the component dominating the signal, 4 days can be sufficient, ... -
Gravity Wave Climatology for Trondheim using a Meteor Radar.
(Master thesis, 2013)In this thesis, a gravity wave climatology for the altitude range of the airglow (hydroxyl) layer of 83 to 91km have been made using data from a meteor radar located at Dragvoll (64,4$^{o}$N, 10,5$^{o}$E) in Trondheim. The ... -
Development of Signal Processing Tools and Analysis of Hyperspectral Imaging Data in Diagnostics of Prion Diseases
(Master thesis, 2013)Creutzfeld-Jakob disease is a invariably deadly prion disease with no cure that attacks the brain. Hyperspectral microscopy has been used to examine 26 amyloid plaques (captured with two different filters) present in ... -
Analysis of Life Regression Models for Censored Data using Pseudo Observations
(Master thesis, 2013)Censoring is a common form for missing data in survival analysis. When a data set is censored, there is only partial knowledge of the survival time of some of the study units. To compensate for this, special techniques and ... -
Oxygen-Controlled Phase Segregation in Poly(N-isopropylacrylamide)/Laponite Nanocomposite Hydrogels
(Journal article; Peer reviewed, 2013) -
The dynamics of DNA denaturation
(Master thesis, 2013)Gaining knowledge and understanding of the structure and function of DNA, our genetic material, is crucial for dealing with diseases related to DNA. In 2004, the mapping of the complete human genome was accomplished, leading ... -
The vertical structure and source regions of large and small scale waves in the middle atmosphere
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:272, Doctoral thesis, 2013)Atmospheric waves are periodic oscillations of the atmospheric variables such as density and temperature, which can have spatial sizes from a few kilometer to thousands of kilometers, and temporal variations from days to ... -
Mapping Orientation Distribution of Talc Particles in Polypropylene by Small-Angle X-ray Scattering Tomography
(Master thesis, 2013)Small-angle X-ray scattering tomography has for the first time been used toinvestigate the spatially resolved orientation distribution of talc particles in asample of injection molded isotactic polypropylene, where the ... -
Laser Induced Incandescence with Long Pulse Duration
(Master thesis, 2013)Laser Induced Incandescence (LII) is a technique used to observe soot concentration and particle size in a flame. The LII signal is captured by an intensified CCD camera. Laser light impacts and heats soot particles within ... -
The effects of Be doping on the structure of Ga and Au-assisted GaAs-based heterostructured semiconductor nanowires.: Effekten av Be-doping på strukturen av Ga og Au-assistert GaAs-baserte heterostructured halvledere nanotråder.
(Master thesis, 2013)The crystal structures of Gallium Arsenide (GaAs) based heterostructured semiconductor nanowires (NW) doped by different beryllium (Be) concentration grown by molecular beam epitaxy were characterized with the help of ... -
Numerical study of the droplet-interface dynamic related to liquid-liquid separators
(Master thesis, 2013)The CFD package OpenFoam with the VOF approach of the interFoam solver is used to simulate water drops in Exxsol D80 oil, with diameter ranging from 100 micrometer to 1000 micrometer. Parasitic currents are caused by the ... -
Anomalous Paths in Quantum Mechanical Path-Integrals
(Journal article; Peer reviewed, 2013)We investigate modifications of the discrete-time lattice action, for a quantum mechanical particle in one spatial dimension, that vanish in the naïve continuum limit but which, nevertheless, induce nontrivial effects due ... -
Casimir friction between dense polarizable media
(Journal article; Peer reviewed, 2013)The present paper—a continuation of our recent series of papers on Casimir friction for a pair of particles at low relative particle velocity—extends the analysis, so as to include dense media. The situation becomes, in ... -
Experimental Studies of Monodisperse Pickering Emulsions Stabilized by Laponite Clay
(Master thesis, 2013)Experiments on oil-in-water Pickering emulsions stabilized by the disc-likesynthetic clay mineral Laponite were performed. Magnetic resonance imagingwas used to determine how the viscosity of the oil, the oil volume ... -
Experimental studies of clay-stabilized oil-in-water emulsions
(Master thesis, 2013)Several experiments concerning clay-stabilized Pickering emulsions have been studied.General emulsion coalescence with and without clay was investigated with optical microscopy.It showed that clay slows down the rate of ... -
