Impacts of UV irradiance and medium-energy electron precipitation on the North Atlantic oscillation during the 11-year solar cycle
(Peer reviewed; Journal article, 2021)Observational studies suggest that part of the North Atlantic Oscillation (NAO) variability may be attributed to the spectral ultra-violet (UV) irradiance variations associated to the 11-year solar cycle. The observed ... -
Implementasjon av Tredimensjonale Elektromagnetiske Kaskader i Elmag
(Master thesis, 2019)En oppdatert versjon av Monte Carlo programmet ELMAG er presentert. Programmet simulerer elektromagnetiske kaskader som startes av høyenergiske fotoner fra blasarer. De høyenergiske fotonene vekselvirker med bakgrunnsfotoner ... -
Implementation and Application of Method for Differential Correlation Network Analysis.
(Master thesis, 2017)A novel framework for differential co-expression networks have recently been developed at the Department of Biotechnology and Food Science at the Norwegian University of Science and Technology (NTNU). The method, referred ... -
Implementation of geometric distortion correction of EPI images in clinical workflow
(Master thesis, 2018)Background: Geometric distortion in echo-planar (EPI) magnetic resonance (MR) images, caused by low bandwidth combined with variations in magnetic susceptibility, is a problem that can make it challenging to connect ... -
Implementation of magnetic resonance imaging in the radiotherapy workflow
(Master thesis, 2019)Tradisjonelt er computertomografi (CT) den mest brukte bildemodaliteten for planlegging av strålebehandling. Magnetisk resonansavbildning (MR) gir langt bedre bløtvevskontrast enn CT, noe som gjør det attraktivt å bruke ... -
Implementing a Full-Band Monte Carlo Model for Zincblende Structure Semiconductors
(Master thesis, 2013)During the work with this master's thesis a number of improvements have been made to the Monte Carlo program being developed at FFI. Algorithms for handling numerical band and scattering rate data have been constructed and ... -
Implementing and reviewing a published cellular automaton model for simulating erosion and deposition processes due to turbidity currents
(Master thesis, 2019)Gruveindustrien har i lengre tid benyttet seg av sjødeponi for lagring av "tailings". I slike sjødeponi er det vanlig at turbiditetsstrømmer oppstår som følge av utslippet, hvilket medfører at partiklene fraktes en lengre ... -
Implementing slice-wise shimming for 7T MRI
(Master thesis, 2022)For å oppnå bilder av høy kvalitet og med godt signal i magnetisk resonansavbildning er homogeniteten til det statiske magnetfeltet avgjørende. Når et legeme introduseres i magneten induseres forvrengninger i feltet på ... -
Implications of Realistic Fracture Criteria on Crack Morphology
(Journal article; Peer reviewed, 2019)We study the effects realistic fracture criteria have on crack morphology obtained in numerical simulations with a stochastic discrete element method. Results are obtained with two criteria which are consistent with the ... -
Improved cyclability of Nickel-rich layered oxides
(Peer reviewed; Journal article, 2020)This study compares the physico- and electro- chemical properties of LiNi0.8Mn0.10Co0.1O2 (NMC811) and LiNi0.83Mn0.06Co0.09Al0.1O2 (NMCA) prepared by an oxalic acid co-precipitation. Deposition of a SiO2 surface coating ... -
Improved domain-wall dynamics and magnonic torques using topological insulators
(Journal article, 2014)We investigate the magnetization dynamics that arises when a thin-film ferromagnet is deposited on a topological insulator (TI), focusing in particular on domain-wall motion via current and the possibility of a spin-wave ... -
Improved drug delivery to brain metastases by peptide-mediated permeabilization of the blood-brain barrier
(Peer reviewed; Journal article, 2019)Patients with melanoma have a high risk of developing brain metastasis, which is associated with a dismal prognosis. During early stages of metastasis development, the blood–brain barrier (BBB) is likely intact, which ... -
Improved resolution Fourier ptychography scheme using oil-filled dome-shaped LED array
(Peer reviewed; Journal article, 2022)Utilising angular-varied illumination in Fourier Ptychography, the resolution of optical microscopes can be increased and the phase of the sample can also be recovered while maintaining a wide field-of-view. In this work, ... -
Improvements of a numerical Algorithm for a certain Class of Colouring Problems
(Master thesis, 2014)We re-derive an algorithm used to calculate solutions for the edge-colouring and dimer problems for planar graphs. The theoretical background for this includes Pfaffian and then as Grassmann Integrals. We develop a new ... -
Improvements to nm scale crystal phase and orientation mapping by physical model comparison
(Master thesis, 2019)Mange teknologiske fremskritt drives av utvikling eller forbedring av nye eller eksisterende materialer. Fordi mange funksjonelle egenskaper henger sammen med den underliggende strukturen til materialet, er materialvitenskap ... -
Improving Accuracy of Computational Light Scattering Simulations by Improved Numerical Integration
(Master thesis, 2014)Numerical integration plays an important role in many large scale physics simulations, yet the accuracy of such computations are often overlooked when the integrator routine is implemented---if the integration result itself ... -
Improving Impurity Photovoltaic Solar Cells via Inhomogeneous Doping Concentrations in Proximity to the Depletion Region
