A random Matrix Approach to collective Trends of falling and rising Stock Markets
Hansen, Christoffer Berge (Master thesis, 2011)An inverse statistics analysis of one minute stock quotes from 492 large Europeancompanies has revealed the existence of a gain-loss asymmetry in thefollowing index. The gain-loss asymmetry differs from that observed for ... -
Advancing Spintronics through Ellipsometric Characterisation of Surface Polaritons
Hale, Nathan Thomas (Doctoral theses at NTNU;2024:133, Doctoral thesis, 2024)Spintronics is a subtopic of magnonics in which the spin of the electron is used to store and process information. Magnonics is the magnetic analogue of the recently popularised field of plasmonics, which deals with the ... -
Approximating Haze in Reflection - Approximate expressions for two-dimensional randomly rough surfaces
Kringstad, Aleksander Hoel (Master thesis, 2015)We give a definition of haze in reflection from two-dimensional surfaces and study this quantity for Gaussian randomly rough surfaces. A simplified model of light scattering, assuming a scalar incident plane wave, the ... -
Asymmetriske Energivariasjoner i Turbulens: Invers statistikk metode for beskrivelse av asymmetrisk energivariasjon
Mersland, Mailinn Blandkjenn (Master thesis, 2011)Energivariasjon i fullt utviklet turbulens er studert. I en tidsserie for tur- bulens energi er det oppdaget en asymmetri mellom positive og negative energiendringer. Invers statistikk metode gir en mulighet til å studere ... -
Atomistic Implications of Stacking Fault Energy on Dislocation - Void Interactions
Hetland, Øyvind Storesund (Master thesis, 2012)Irradiation hardening due to voids can be a significant result of radiation damage in metals, but treatment of this by elasticity theory of dislocations is difficult when the mechanisms controlling the obstacle strength ... -
Bitemporal Electromagnetism and the Antiphoton
Makaris, Ivan (Master thesis, 2023)Til tross for dens tentative unøyaktigheter og noe uklare teoretiske grunnlag, viser Tore Wessel-Bergs teori om bitemporal elektromagnetisme, en tilsynelatende klassisk teori, en overraskende evne til å predikere kvantefenomener ... -
Colloidal Crystals as Templates for Light Harvesting Structures in Solar Cells
Haugan, Einar (Master thesis, 2011)Monolayer colloidal crystals are formed using silica- and polystyrene beads and used as templates in nanosphere lithography for creating various hexagonal periodic structures intended for light harvesting in crystalline ... -
Complex Networks: Development of a three particle reaction-diffusion model on a complex network.
Brende, Ole Martin (Master thesis, 2011)This master thesis couples endemic modeling of diseases with complex networks and diffusion. Previous established models are visited and results for these are reproduced. The goal of this thesis was to expand upon these ... -
Degree of polarization of light scattered from correlated surface and bulk disorders
Banon, Jean-Philippe Armand; Simonsen, Ingve; Carminati, Rémi (Journal article; Peer reviewed, 2023)Using a single scattering theory, we derive the expression of the degree of polarization of the light scattered from a layer exhibiting both surface and volume scattering. The expression puts forward the intimate connection ... -
Development of a compact radiation monitor for space application
Stein, Timo Alexander (Master thesis, 2015)In this work a compact radiation monitor prototype has been developed. The present device and its technology will directly contribute towards the CPT-SCOPE project, a Norwegian-German student project developing a radiation ... -
Diffusjon av vann i sotfylte kappematerialer for polymere sjøkabler
Håkonseth, Gunnar (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 ... -
Dispersion of polarization coupling, localized and collective plasmon modes in a metallic photonic crystal mapped by Mueller Matrix Ellipsometry
Kildemo, Morten; Brakstad, Thomas; Ghadyani, Zahra; Simonsen, Ingve (Journal article; Peer reviewed, 2015)We report a spectroscopic Mueller matrix experimental study of a plasmonic photonic crystal consisting of gold hemispheroidal particles (lateral radius 54 nm, height 25 nm) arranged on a square lattice (lattice constant ... -
Distribution of ground impact locations for unmanned fixed-wing aircraft descending in turbulent conditions
Kolden, Herman Øie (Master thesis, 2021)Abstract will be available on 2023-08-28 -
Does the Boson Peak Exist in 2D Materials?
Tømterud, Martin (Master thesis, 2021)Glass og andre uordnede materialer som polymerer er umåtelig viktige i det moderne samfunn. Å forstå deres egenskaper er derfor essensielt. Et fenomen som ofte er observert i bulk i glass er bosontoppen, en overflod av ... -
Electromagnetic Scattering Calculations for Arbitrarily Shaped Closed Surfaces using the Method of Moments
Øyre, Eilif Sommer (Master thesis, 2021)I denne oppgaven løses Maxwells likninger numerisk for det elektromagnetiske spred-ningsproblemet i to regioner ved bruk av overflateintegrallikninger og momentmeto-den. For å kunne diskretisere de ekvivalente strømmene ... -
Electromagnetic Scattering: A Surface Integral Equation Formulation
Aas, Rune Øistein (Master thesis, 2012)A numerical approach to solving the problem of electromagnetic (EM) scattering on a single scatterer is studied. The problem involves calculating the total EM field in arbitrary observation points when a planar EM wave is ... -
Engineered Surfaces for Redirection of Light
Walle, Øystein (Master thesis, 2011)It is of interest to construct windows that can spread the transmitted light in a specified manner. The Kirchhoff approximation in the geometrical optical limit in combination with a chosen general form of the window ... -
Entropy in Dynamical Networks
Uthushagen, Kristian Siegel (Master thesis, 2013)This thesis presents a new type of dynamical entropy, defined by the movement of particles beetween the nodes in a network. The entropy is intended to have similar properties as the well-known thermodynamic entropy. ... -
