Investigating the prospect of using the yellow fluorescent protein mutant YFP3G as a pressure sensor in plants
(Master thesis, 2018)Plants have no skeleton, but instead get their structural support from a hydrostatic pressure called turgor pressure pressing against a strong cell wall. This pressure can reach up to 2 MPa, and is also an important part ... -
Investigation of Raman scattering phenomena in the development of mid-IR ultra-short laser pulses
(Master thesis, 2015)In this thesis both a raman spectrometer and a dispersion measurement setup for fibers was designed, built and automatized. Furthermore several nonlinear phenomena were researched and with two different approaches simulated. ... -
Investigation of Unoccupied Electronic Bands in Graphene
(Master thesis, 2018)In recent years, a lot attention has been paid to various two-dimensional materials due to their unique properties stemming from the spacial refinement of one of the material's dimensions. Regardless of the incredible ... -
Iron oxide nanocrystals clustered in oil-in-water nanoemulsions: Preparation, characterization, and transverse relaxivities
(Master thesis, 2015)Iron oxide nanocrystals (IONCs) have attracted extensive interest due to their high magnetization that efficiently decreases the transverse relaxation times of water protons. The increase in their transverse relaxivities ... -
Linearized general relativity and its quantization
(Master thesis, 2017)We begin by deriving the Einstein equation from the Einstein-Hilbert action integral using variational methods; Variation with respect to the metric and the Palatini variation. The vacuum solution (Schwarzschild solution) ... -
Maximum Likelihood Analysis of IceCube Data: - Could Decaying Dark Matter explain the high energy Neutrino Excess?
(Master thesis, 2015)In this theoretical physics master thesis I've looked at a set of observations from a neutrino observatory in Antarctica called IceCube. This observatory has observed more high energy neutrinos than expected. I wanted to ... -
Modelling of spectroscopic Mueller matrices of ordered nanoplasmonic surfaces using the finite element method
(Master thesis, 2017)This thesis is focused on modelling the complete polarization dependent optical response resulting from reflection from periodic nanostructures with a two-dimensional lattice, using the commercial software COMSOL Multiphysics ... -
Monte Carlo Simulation of Photoconductive Terahertz Sources in Mercury Cadmium Telluride
(Master thesis, 2016)In this master's thesis we explore the physics of a photoconductive terahertz emitter and diverse methods to increase its power emission. A way to simulate it via a Monte Carlo first principle simulator is presented, taking ... -
Monte Carlo simulation to study the interaction between the weak polyelectrolytes and two oppositely charged nano particles. Influence of nano particle separation and pH variation.
(Master thesis, 2017)Primitive model of electrolyte is used as it provides a good basis for the statistical mechanical description of the charged colloids. The colloidal solution on aqueous form is represented by the mixture of hard spheres ... -
MYOCARDIAL STRAIN MEASUREMENTS WITH MRI USING FEATURE TRACKING
(Master thesis, 2016)Myocardial strain is increasingly used in determination of myocardial function in the medical field due to its ability to detect cardiac diseases in the early stages, its ability to quantify regional myocardial function ... -
Neutron stars - Investigating candidates for the equation of state in the relativistic mean-field approximation
(Master thesis, 2018)Various models for the equation of state (EoS) for a neutron star have been considered using the relativistic mean-field approximation. Firstly, we derive Einstein's field equations and apply them to a spherically symmetric ... -
Neutron Stars - Study of the Mass-Radius Relation and Mean-Field Approaches to the Equation of State
(Master thesis, 2017)The structure and the relation between the total mass, the radius and the central energy density of a neutron star may be found by numerically solving a set of three coupled differential equations. One of these equations ... -
Non-equilibrium quantum effects in hybrid structures of ferromagnets and superconductors
(Master thesis, 2016)The quasiclassical theory of superconductivity is applied to diffusive nanowires connecting normal-metal and superconducting bulk materials. The diffusion equations for ferromagnetic junctions with spin-orbit coupling are ... -
Novel Studies of the Spectroscopic Signature of the Skin Cancer-causing Cyclobutane Cross-link in DNA
(Master thesis, 2018)1,2,3,4-Cyclobutanetetracarboxylic acid was chosen as a drastically simplified model of the cyclobutane pyrimidine dimer in DNA. Its interaction with cisplatin was studied by XPS i.a. at the synchrotron light source ASTRID2 ... -
Optical Properties of Silicon Microwire Arrays for Photovoltaic Applications
(Master thesis, 2015)Silicon microwire-based solar cells represent a potential design strategy to reduce wafer related costs through reduced material usage and relaxed purity requirements. In this work we investigate the absorption of incident ... -
Permeability, Growth and Morphology of Coastal Ice - Site Study in Van Mijenfjorden, Svalbard
(Master thesis, 2015)Coastal ice includes the parts of the sea ice that are stressed and deformed by tidal motion; the ice foot (the inner part that is frozen to the ground) and the hinge zone (the zone where cracking occurs due to tidal ... -
Plasma Instabilities in Electron-Positron Pair Beams from Blazars
(Master thesis, 2018)The non-detection of an electromagnetic cascade in the electron-positron plasma beams from blazars has led many physicists to invoke an intergalactic magnetic eld that de ects charged particles away from our eld of view. ... -
Prediction of Protein Function using semantic Fingerprints - Multivariate Data Classification by Artificial Neural Networks involving dimensional Reduction
