A random Matrix Approach to collective Trends of falling and rising Stock Markets
(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 ... -
A Renormalization Group Procedure for Fiber Bundle Models
(Journal article; Peer reviewed, 2018)We introduce two versions of a renormalization group scheme for the equal load sharing fiber bundle model. The renormalization group is based on formulating the fiber bundle model in the language of damage mechanics. A ... -
A review of materials engineering in silicon-based optical fibre
(Journal article; Peer reviewed, 2017)Semiconductor optical fibre technologies have grown rapidly in the last decade and there are now a range of production and post-processing techniques that allow for a vast degree of control over the core material's ... -
A Scanning Tunneling Microscope for Point Contact Investigations of Magnetodynamics in FeMn/FeNi Bilayers
(Master thesis, 2009)This thesis presents the development of a scanning tunneling microscope purpose built for point contact investigations of magnetodynamics. The contributed changes include new measurement electronics, with 40-60% improvement ... -
A simple way for targeted delivery of an antibiotic: In vitro evaluation of a nanoclay-based composite
(Journal article; Peer reviewed, 2017)The sodium-modified form of fluorohectorite nanoclay (NaFh) is introduced as a potential drug carrier, demonstrating its ability for the controlled release of the broad-spectrum antibiotic Ciprofloxacin through in vitro ... -
A Simulated Annealing Approach to Electrical Resistivity Tomography
(Master thesis, 2018)In this study, a new approach to Electrical Resistivity Tomography (ERT) data inversion was investigated. ERT is a geophysical method for imaging the subsurface. An electrical current is injected into the surface, and the ... -
A Soft-Limit Theorem for the On-Shell Scattering Amplitudes Describing Processes Involving Massive Nambu-Goldstone Bosons
(Master thesis, 2017)In this thesis we consider systems where both Lorentz invariance and a continuous symmetry group G is explicitly broken by coupling a chemical potential µ to one of the generators Q of G. In such systems it is well known ... -
A Spectroscopic Study of in situ Magnetic Doping of Novel Layered Materials for Spintronics
(Master thesis, 2016)MoS2 is a layered material in the family of the transition metal dicalchogenides (TMDCs), which hosts interesting spin physics. Even though the TMDCs are nonmagnetic in their bulk form, a local breaking of inversion symmetry ... -
A study of 1998-2008 Brewer Mk V: Spectrophotometer UV-measurements in Oslo

A Study of Chemical Potential Influenced by Parametric Pumping of Antiferromagnetic Magnons
(Master thesis, 2019)Et blomstrende forskningsfelt i nyere tid omfatter Bose-Einstein kondensasjon (BEC) av magnoner i antiferromagneter. En lovende metode for å manipulere eksitasjon av magnoner er parametrisk parallell pumping (PPP). Ved å ... -
A Study of Cultured Cells on a Nanowire-based Reverse Transfection Device
(Master thesis, 2011)This work builds on previous research at NTNU into the use of vertically aligned copper oxide nanowire arrays as a versatile system to deliver biomolecules into cultured adherent mammalian cells. The background for the ... -
A Study of Rotational Water Waves using Bifurcation Theory
(Master thesis, 2014)This thesis is concerned with the water wave problem. Using local bifurcation we establish small-amplitude steady and periodic solutions of the Euler equations with vorticity. Our approach is based on that of Ehrnström, ... -

A TEM study of the precipitates in a 6082 Al-Mg-Si alloy system
(Dr. ingeniøravhandling, 0809-103X; 2000:103, Doctoral thesis, 2001)The purpose of this work has been to gain a better understanding of the details of the precipitation sequence in Al-Mg-Si alloys. Because of the complexity of such ternary systems is has been necessary to limit the study ... -
A Theoretic Study of β'' Misfits and Strain in Al-Mg-Si Alloys - A Cluster-Based Approach Combining Density Functional Theory and Linear Elasticity
(Master thesis, 2018)Heat treatable aluminium alloys of the 6xxx series are important for many industrial applications in the modern world. They contain small amounts of the alloying elements magnesium and silicon, which cluster together to ... -
