Selected x86 Low-level Attacks and Mitigations
(Doctoral thesis, 2017)Low-level exploitation is an ongoing security issue. History has shown multiple methods to gain control over, and control, the flow of execution, as well as multiple methods and approaches to mitigate the same issue. This ... -
Decoding and constructions of codes in rank and Hamming metric
(Doctoral thesis, 2022-05-27)As coding theory plays an important role in data transmission, decoding algorithms for new families of error correction codes are of great interest. This dissertation is dedicated to the decoding algorithms for new families ... -
Quantitative Magnetic Resonance Imaging of Tissue Microvasculature and Microstructure in Selected Clinical Applications
(Doctoral thesis, 2022-06-03)This thesis is based on four papers and aims to establish perfusion and diffusion measurements with magnetic resonance imaging (MRI) in selected clinical applications. While structural imaging provides invaluable geometric ... -
Problem solving in basic physics: Effective self-explanations based on four elements with support from retrieval practice
(Journal article; Peer reviewed, 2022)Self-explanation, a learning strategy where students explain to themselves the steps taken in a worked example, is an effective learning strategy in early cognitive skill acquisition. However, many physics students produce ... -
Order-Related Problems Parameterized by Width
(Doctoral thesis, 2022-05-25)In the main body of this thesis, we study two different order theoretic problems. The first problem, called Completion of an Ordering, asks to extend a given finite partial order to a complete linear order while respecting ... -
Reproduction and pollination in bilberry (Vaccinium myrtillus) along two elevational gradients in western Norway
(Master thesis, 2022-03-22) -
Modelling of gas hydrates in sedimentary systems : Methane hydrates impact on flow through porous media
(Doctoral thesis, 2022-04-06)In nature, gas hydrates exist in areas of permafrost and in shallow subsurface sediments at ocean depths of more than 300-500 metres. In terms of the Sustainable Development Goals (SDG) of the United Nations, better ... -
Winters are changing: snow effects on Arctic and alpine tundra ecosystems
(Journal article; Peer reviewed, 2022)Snow is an important driver of ecosystem processes in cold biomes. Snow accumulation determines ground temperature, light conditions and moisture availability during winter. It also affects the growing season’s start and ... -
Relative Spatial Positions of Tryptophan and Cationic Residues in Helical Membrane-active Peptides Determine Their Cytotoxicity
(Journal article; Peer reviewed, 2012)The cytotoxic activity of 10 analogs of the idealized amphipathic helical 21-mer peptide (KAAKKAA)3, where three of the Ala residues at different positions have been replaced with Trp residues, has been investigated. The ... -
Efficient Monte Carlo simulation reveals significant multiple scattering errors in underwater angular scattering measurements
(Journal article; Peer reviewed, 2022)Multiple scattering can severely affect the accuracy of optical instrumentation. Variance reduction methods have been implemented to improve a Monte Carlo model developed to simulate volume scattering functions measured ... -
Rotational effects on exchange flows across a submerged sill
(Journal article; Peer reviewed, 2021)This paper presents new laboratory-scale numerical simulations of density-driven exchange flows generated across an idealised, submerged sill obstruction under both non-rotating and rotating frames of reference using the ... -
Hidden semi-Markov-switching quantile regression for time series
(Journal article; Peer reviewed, 2021)A hidden semi-Markov-switching quantile regression model is introduced as an extension of the hidden Markov-switching one. The proposed model allows for arbitrary sojourn-time distributions in the states of the Markov-switching ... -
Dispersive Estimates for Full Dispersion KP Equations
(Journal article; Peer reviewed, 2021)We prove several dispersive estimates for the linear part of the Full Dispersion Kadomtsev–Petviashvili introduced by David Lannes to overcome some shortcomings of the classical Kadomtsev–Petviashvili equations. The proof ... -
Underwater Ultrasonic Transducer Technology. Construction, Characterization and Finite-Element Modelling.
(Master thesis, 2022-03-30)The main objective of this thesis is to construct and characterize ultrasonic transducers. The transducers are constructed to get the information needed for finite element simulations with the wanted accuracy since commercial ... -
Satellite altimetry for Indian reservoirs
(Journal article; Peer reviewed, 2021)Satellite radar altimetry has immense potential for monitoring fresh surface water resources and predicting the intra-seasonal, seasonal, and inter-annual variability of inundated surface water over large river basins. As ... -
Polycyclic aromatic hydrocarbons (PAHs) and their nitrated and oxygenated derivatives in the Arctic boundary layer: Seasonal trends and local anthropogenic influence
(Journal article; Peer reviewed, 2021)A total of 22 polycyclic aromatic hydrocarbons (PAHs), 29 oxy-PAHs, and 35 nitro-PAHs (polycyclic aromatic compounds, PACs) were measured in gaseous and particulate phases in the ambient air of Longyearbyen, the most ... -
Engaging students in SDG 14 by placing them at the centre of their own learning: SDG214 at the University of Bergen as an example
(Chapter, 2021)Educating students on the sustainable development goals (SDGs) calls for teaching where students are at the centre of their own learning. Sustainability questions are ‘wicked problems’, where no single, correct answer ... -
A mathematical justification of the momentum density function associated to the KdV equation
(Journal article; Peer reviewed, 2021)Consideration is given to the KdV equation as an approximate model for long waves of small amplitude at the free surface of an inviscid fluid. It is shown that there is an approximate momentum density associated to the KdV ... -
Wind-Driven Variability in the Spitsbergen Polar Current and the Svalbard Branch Across the Yermak Plateau
(Journal article; Peer reviewed, 2021)The Yermak Plateau (YP) acts as a guidance or barrier for the West Spitsbergen Current (WSC), which either crosses the plateau or flows around it to enter the Arctic Ocean. Closer to the West Spitsbergen coast, the Spitsbergen ... -
Structure and drivers of ocean mixing north of Svalbard in summer and fall 2018
(Journal article; Peer reviewed, 2021)The Arctic Ocean is a major sink for heat and salt for the global ocean. Ocean mixing contributes to this sink by mixing the Atlantic- and Pacific-origin waters with surrounding waters. We investigate the drivers of ocean ...
