Statistical Properties of Opening and Closing Auctions of U.S. Bourses
(Master thesis, 2017)Major stock exchanges typically open and close by employing so-called single-price auctions. The auctions work by gathering orders through a pre-auction period, finding the price that match the greatest quantity of buy and ... -
Study of FeSi Interlayers Formed During Iron-Mediated Epitaxial Growth of Graphene on SiC Substrates
(Master thesis, 2016)A proposed graphene integrated semiconductor radiation sensor takes advantage of the electric field effect in graphene by measuring the change in resistance as a function of radiation exposure to the semiconductor substrate. ... -
Superconductivity in Dirac Materials
(Master thesis, 2016)In this Master s thesis we consider superconductivity in Bravais and bipartite lattice fermion models with nearest neighbour hopping and Rashba-type spin-orbit coupling. The superconductivity is modelled from a negative-U ... -
TEM of Chromium doped Zinc Sulfide Thin Films for Solar Cell Applications.
(Master thesis, 2015)To Cr dopede ZnS tynnfilmer grodd ved forskjellig temperatur har blitt undersøkt med transmisjons elektronmikroskopi. Krystallstrukturen til filmene ble undersøkt med høyoppløsningsbilder og diffraksjonsmønstre. Begge ... -
Temperature coefficients in compensated silicon materials for solar cells
(Master thesis, 2017)The pricing of solar modules is closely connected to the rating at standard testing conditions (STC). Lately more emphasis has been put on the relationship between field performance of PV-modules and the temperature ... -
Terahertz Time-Domain Spectroscopy of Thin Material Samples
(Master thesis, 2015)This thesis describes the techniques used in terahertz time-domain spectroscopy to determine the optical properties of layers that are thin compared to the length of the terahertz pulse. An iterative procedure is used to ... -
The Distribution of Spatial Phases of Grid Cells
(Master thesis, 2015)Grid cells, found in the medial entorhinal cortex of mammalian brains, are among the most significant discoveries from the research into the brain's system for spatial navigation during the last decades. A lot of work has ... -
The effect of deformation and natural ageing in an Al-Mg-Si-Cu alloy with high Cu-content: A transmission electron microscopy study
(Master thesis, 2018)The effect of the combination of natural ageing and deformation to 80 % on precipitation in an Al-Mg-Si-Cu alloy has been investigated by different transmission electron microscopy (TEM) techniques. Similar research is ... -
The Lattice Boltzmann Method for Steady State Sediment Transport.
(Master thesis, 2016)Simulating water behaviour in coastal areas is an important tool when predicting sedimentary processes over geological time. We implement a general lattice Boltzmann model for shallow water flow, that can handle having ... -
The Vacuum Polarisation Contribution to the Lamb Shift Using Non-Relativistic Quantum Electrodynamics
(Master thesis, 2016)In this thesis we calculate the vacuum polarisation contribution to the well-known Lamb shift. The Lamb shift is a correction of order $\alpha^5$ to the non-relativistic energy spectrum of the hydrogen atom. We discuss the ... -
Transmission Electron Microscopy Characterisation of Lead-Free KNN Thin Films
(Master thesis, 2018)Lead-free piezoelectric ceramics have in recent years received an increased interest. Potassium sodium niobate (KNN) has shown promising results, exhibiting properties close to todays dominating piezoelectric material lead ... -
Two Dimensional Fiber Bundle Bridge Model
(Master thesis, 2016)The two dimensional fiber bundle bridge model is introduced, derived and studied for an uniform threshold distribution. The model is independent of history and has an adjustable effective range of interaction, which is ... -
Understanding complementarity-based security proofs of quantum key distribution with imperfect sources
(Master thesis, 2017)We present a study of modern security proofs of quantum key distribution based on complementarity. This is a quantum communication protocol allowing for provable, unconditional security, although there is still a gap between ... -
Utregning av det elektromagnetiske feltet i Monte Carlo transport simulering
(Master thesis, 2017)Løsning av poissons ligning under monte carlo simulering av en CdHgTe fotoskred-diode. Vi har tatt i bruk ikke-uniform mesh med adaptivt grid og gjort noen elementære simuleringer av CMT dioden.
