Coupled effects of wave and depth-dependent current interaction on loads on a bottom-fixed vertical slender cylinder
(Journal article; Peer reviewed, 2023)The coupled effects of waves and a subsurface current on the hydrodynamic loads on offshore slender structures in coastal water regions have been examined in this paper, especially the coupling of the weak nonlinearity of ... -
Covering tour problem with varying coverage: Application to marine environmental monitoring
(Journal article; Peer reviewed, 2023)In this paper, we present a novel variant of the Covering Tour Problem (CTP), called the Covering Tour Problem with Varying Coverage (CTP-VC). We consider a simple graph 𝐺 = (𝑉 ,𝐸), with a measure of importance assigned ... -
Critical Measures and Parameter Space of Jenkins-Strebel Quadratic Differentials
(Master thesis, 2012-05-07)The thesis is devoted to applications of the theory of quadratic differentials to the problems of construction of critical measures, that provide critical values of the logarithmic energy of a charge system on the complex ... -
Crustal Conditions Favoring Convective Downward Migration of Fractures in Deep Hydrothermal Systems
(Journal article; Peer reviewed, 2023)Cooling magma plutons and intrusions are the heat sources for hydrothermal systems in volcanic settings. To explain system longevity and observed heat transfer at rates higher than those explained by pure conduction, the ... -
CSF circulation and dispersion yield rapid clearance from intracranial compartments
(Journal article; Peer reviewed, 2022-09-12)In this paper, we used a computational model to estimate the clearance of a tracer driven by the circulation of cerebrospinal fluid (CSF) produced in the choroid plexus (CP) located within the lateral ventricles. CSF was ... -
Cubical and cosimplicial descent
(Peer reviewed; Journal article, 2018)We prove that algebraic K ‐theory, topological Hochschild homology and topological cyclic homology satisfy cubical and cosimplicial descent at connective structured ring spectra along 1‐connected maps of such ring spectra. -
Curvature and Harmonic Forms on Complete Manifolds
(Master thesis, 2023-01-18) -
Cyclic homology in a special world
(Chapter, 2020)In work of Connes and Consani, Γ-spaces have taken a new importance. Segal introduced Γ-spaces in order to study stable homotopy theory, but the new perspective makes it apparent that also information about the unstable ... -
Daily Contributors of Tinnitus Loudness and Distress: An Ecological Momentary Assessment Study
(Journal article; Peer reviewed, 2022)Background: Tinnitus is a heterogeneous condition which may be associated with moderate to severe disability, but the reasons why only a subset of individuals is burdened by the condition are not fully clear. Ecological ... -
Danning av kvervlar og frontar på sub-mesoskala i havet

DarSIA: An Open-Source Python Toolbox for Two-Scale Image Processing of Dynamics in Porous Media
(Journal article; Peer reviewed, 2023)Understanding porous media flow is inherently a multi-scale challenge, where at the core lies the aggregation of pore-level processes to a continuum, or Darcy-scale, description. This challenge is directly mirrored in image ... -
Data on gender contrasts in the risk of incident myocardial infarction by age. The Tromsø Study 1979-2012
(Peer reviewed; Journal article, 2017-08)The data presented in this article relate to the research article entitled “Risk of incident myocardial infarction by gender: Interactions with serum lipids, blood pressure and smoking. The Tromsø Study 1979–2012” (Albrektsen ... -
Data science approaches provide a roadmap to understanding the role of abscisic acid in defence
(Journal article; Peer reviewed, 2023)Abscisic acid (ABA) is a plant hormone well known to regulate abiotic stress responses. ABA is also recognised for its role in biotic defence, but there is currently a lack of consensus on whether it plays a positive or ... -
Data-Driven Inference Reveals Distinct and Conserved Dynamic Pathways of Tool Use Emergence across Animal Taxa
(Journal article; Peer reviewed, 2020)Tool use is a striking aspect of animal behavior, but it is hard to infer how the capacity for different types of tool use emerged across animal taxa. Here we address this question with HyperTraPS, a statistical approach ... -
DCC-GARCH modeller med ulike avhengighetsstrukturer
(Master thesis, 2013-03-14)Hovedfokuset i denne oppgaven er å finne gode metoder for modellering av volatilitet og avhengighetsstruktur i finansielle porteføljer. En spesifikk multivariat GARCH modell, Dynamic Conditional Correlation (DCC-) GARCH, ... -
Decay estimates of Green's matrices for discrete-time linear periodic systems
(Journal article; Peer reviewed, 2023)We study periodic Lyapunov matrix equations for a general discrete-time linear periodic system Bpxp−Apxp−1=fp, where the matrix coefficients Bp and Ap can be singular. The block coefficients of the inverse operator of the ... -
Decay of solitary waves of fractional Korteweg-de Vries type equations
(Journal article; Peer reviewed, 2023)We study the solitary waves of fractional Korteweg-de Vries type equations, that are related to the 1- dimensional semi-linear fractional equations: |D|αu + u − f (u) = 0, with α ∈ (0, 2), a prescribed coefficient p∗(α), ... -
Decline in temperature variability on Svalbard
(Journal article; Peer reviewed, 2020)The variability in the temperature on Svalbard, Norway, has been decreasing over the last four decades. This may be due to the reduction in sea ice, transitioning the regional climate to a more stable, coastal one.We ... -
