The Norwegian Stock Market: - A Local Gaussian Perspective
(Master thesis, 2013-06-03)In this thesis, using daily returns from 18 stocks, oil price, exchange rates and the main index of the Oslo Stock Exchange over a period of 5 years, we investigate how the Local Gaussian Correlation can be used to describe ... -
Not that clean: Aquaculture-mediated translocation of cleaner fish has led to hybridization on the northern edge of the species' range
(Journal article; Peer reviewed, 2021)Translocation and introduction of non-native organisms can have major impacts on local populations and ecosystems. Nevertheless, translocations are common practices in agri- and aquaculture. Each year, millions of wild-caught ... -
Not too slow, not too fast: water currents affect group structure, aggression and welfare in post-smolt Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2016)Increased swimming speed of Atlantic salmon is generally considered an improvement to welfare under aquaculture settings, as group structure is improved and agonistic behaviour reduced. As such, establishing fish farms in ... -
A Note on Exact Algorithms for Vertex Ordering Problems on Graphs
(Peer reviewed; Journal article, 2011-01-21)In this note, we give a proof that several vertex ordering problems can be solved in O ∗(2 n ) time and O ∗(2 n ) space, or in O ∗(4 n ) time and polynomial space. The algorithms generalize algorithms for the Travelling ... -

A note on Severi varieties of nodal curves on Enriques surfaces
(Journal article; Peer reviewed, 2020)Let |L| be a linear system on a smooth complex Enriques surface S whose general member is a smooth and irreducible curve of genus p, with L2 > 0, and let V|L|,δ(S) be the Severi variety of irreducible δ-nodal curves in ... -
A note on some algebraic trapdoors for block ciphers
(Peer reviewed; Journal article, 2018)We provide sufficient conditions to guarantee that a translation based cipher is not vulnerable with respect to the partition-based trapdoor. This trapdoor has been introduced, recently, by Bannier et al. (2016) and it ... -
A note on the multiphase balance equations
(Journal article; Peer reviewed, 2020)The formulation and use of the momentum equations for multiphase systems are not always consistent in the literature. The objective of this note is to clarify an issue, which long has hounded the literature on the multiphase ... -

Notes on Lattice-Based Cryptography
(Doctoral thesis, 2022-09-06)Asymmetrisk kryptering er avhengig av antakelsen om at noen beregningsproblemer er vanskelige å løse. I 1994 viste Peter Shor at de to mest brukte beregningsproblemene, nemlig det diskrete logaritmeproblemet og ... -
Notochord development in Atlantic salmon (Salmo salar L.): exploring molecular pathways and putative mechanism of segmentation
(Doctoral thesis, 2014-03-07)Background: A key feature of the vertebrate body plan is the repeated compartments made up of individual vertebra, blood vessels, peripheral nerves and muscle. The vertebral column comprises a series of bony vertebral ... -
The notochord in Atlantic salmon (Salmo salar L.) undergoes profound morphological and mechanical changes during development
(Peer reviewed; Journal article, 2017-11)We present the development of the notochord of the Atlantic salmon (Salmo salar L.), from early embryo to sexually mature fish. Over the salmon's lifespan, profound morphological changes occur. Cells and gross structures ... -
Novel 3D Pixel Sensors for the Upgrade of the ATLAS Inner Tracker
(Journal article; Peer reviewed, 2021)The ATLAS experiment will undergo a full replacement of its inner detector to face the challenges posed by the High Luminosity upgrade of the Large Hadron Collider (HL-LHC). The new Inner Tracker (ITk) will have to deal ... -
Novel and colourful flavonoids - characterisation, secondary structures and properties
(Doctoral thesis, 2021-06-03)This dissertation focuses on isolation and structural elucidation of flavonoid pigments. The properties of these pigments have been explored, in terms of their chemical properties, especially regarding secondary structures ... -
Novel and Unexpected Microbial Diversity in Acid Mine Drainage in Svalbard (78° N), Revealed by Culture-Independent Approaches
(Peer reviewed; Journal article, 2015-10-13)Svalbard, situated in the high Arctic, is an important past and present coal mining area. Dozens of abandoned waste rock piles can be found in the proximity of Longyearbyen. This environment offers a unique opportunity for ... -
A Novel Approach to Acoustic Liquid Density Measurements Using a Buffer Rod Based Measuring Cell
