Computational search for isotopic semifields and planar functions in characteristic 3
(Master thesis, 2023-09-01)In this thesis, we investigate the possibility of finding new planar functions and corresponding semifields in characteristic 3 by the construction of isotopic semifields from the known families and sporadic instances of ... -
Computational searches for quadratic APN functions with subfield coefficients
(Master thesis, 2023-06-01)Almost perfect nonlinear (APN) functions are important in fields such as algebra, combinatorics, cryptography, etc. Finding new APN functions is of special importance in cryptography. This is because when used in modern ... -
Computationally Efficient Methods for Seismic Modeling and Inversion
(Doctoral thesis, 2020-11-18)This thesis presents new methods for the modeling of seismic waveforms based on ray theory and ray-Born integrals. The waveforms are used in forward modeling, imaging and full waveform inversion and are computed in 3D ... -
Computer-aided proofs and algorithms in analysis
(Doctoral thesis, 2013-06-14)The computational power has increased dramatically since the appearance of the first computers, making them a vital tool in the analysis of dynamical systems. We present further applications of those two basic ideas, namely ... -

Computing Connected Components on Multiple GPUs
(Master thesis, 2018-12-19)We look at multiple GPU programming, using the connected components algorithm as the basis when we look into libraries and runtime environment for multiple GPU programming. We also show that Rem is a fast parallel algorithm, ... -
Computing cutwidth and pathwidth of semi-complete digraphs via degree orderings
(Peer reviewed; Journal article, 2013)The notions of cutwidth and pathwidth of digraphs play a central role in the containment theory for tournaments, or more generally semi-complete digraphs, developed in a recent series of papers by Chudnovsky, Fradkin, Kim, ... -

Computing the distance to continuous-time instability of quadratic matrix polynomials
(Journal article; Peer reviewed, 2020)A bisection method is used to compute lower and upper bounds on the distance from a quadratic matrix polynomial to the set of quadratic matrix polynomials having an eigenvalue on the imaginary axis. Each bisection step ... -

Concentrations and endocrine disruptive potential of phthalates in marine mammals from the Norwegian Arctic
(Journal article; Peer reviewed, 2021)This study investigated concentrations of phthalates (diesters of phthalic acids) in blubber/adipose tissue of blue whales (Balaenoptera musculus), fin whales (Balaenoptera physalus), bowhead whales (Balaena mysticetus) ... -
Concept analysis and life cycle assessment of large-scale, offshore hydrogen production, storage and distribution options
(Master thesis, 2022-06-01)The world and its inhabitants are facing pressing challenges related to the global warming of the Earth. The increasing share of renewable electricity is forecasted to decrease emissions of greenhouse gases, but electrification ... -
A conceptual geological model for offshore wind sites in former ice stream settings: The Utsira Nord site, North Sea
(Journal article; Peer reviewed, 2022)Conceptual geological models of the shallow subsurface that integrate geological and geotechnical information are important for more strategic data acquisition and engineering at offshore wind sites. Utsira Nord is an ... -
Concurrent jellyfish blooms and tenacibaculosis outbreaks in Northern Norwegian Atlantic salmon (Salmo salar) farms
(Peer reviewed; Journal article, 2017-11-02)Tenacibaculosis is an increasing problem in the Norwegian Atlantic salmon aquaculture industry causing significant economic losses. In September 2015, two separate outbreaks of suspected tenacibaculosis occurred at two ... -
Condensation of water on rust surfaces, and possible implications for hydrate formation in pipelines
(Master thesis, 2011-06-01)The threat of climate change has put the spotlight on the increase in carbon emissions and possible methods to attenuate it. As a consequence of this, oil and gas companies have started to consider both how to reduce ... -
Conditioning reservoir models on vast data sets
(Doctoral thesis, 2021-09-09)History matching is a valuable process to obtain better models and a more reliable forecast in oil reservoir applications. In such processes, one conditions the simulation models on the observed data from the field. One ... -
Conditions favouring hard seededness as a dispersal and predator escape strategy
(Peer reviewed; Journal article, 2014-09-16)1. The water-impermeable seed coat of ‘hard’ seeds is commonly considered a dormancy trait. Seed smell is, however, strongly correlated with seed water content, and hard seeds are therefore olfactionally cryptic ... -
Cone-Size Dependence of Jet Suppression in Heavy-Ion Collisions
(Journal article; Peer reviewed, 2021)The strong suppression of high-pT jets in heavy-ion collisions is a result of elastic and inelastic energy loss suffered by the jet multiprong collection of color charges that are resolved by medium interactions. Hence, ... -
Configuration and performance of the ATLAS b-jet triggers in Run 2
(Journal article; Peer reviewed, 2021)Several improvements to the ATLAS triggers used to identify jets containing b-hadrons (b-jets) were implemented for data-taking during Run 2 of the Large Hadron Collider from 2016 to 2018. These changes include reconfiguring ... -
Configuration of the Scandinavian Ice Sheet in southwestern Norway during the Younger Dryas
(Journal article; Peer reviewed, 2023)The extent of the Scandinavian Ice Sheet in southwestern Norway is precisely located during the well-characterized Younger Dryas re-advance. However, the thickness of the ice sheet is less well constrained inland from the ...
