The left heart and exact hull of an additive regular category
(Journal article; Peer reviewed, 2023)However, there are natural examples of categories in functional analysis which are not quasi-abelian, but merely one-sided quasi-abelian or even weaker. Examples are the category of LB-spaces or the category of complete ... -
LES and RANS simulation of onshore Bessaker wind farm: analyzing terrain and wake effects on wind farm performance
(Journal article; Peer reviewed, 2015)This work compares the predictive performance of RANS and LES solver in capturing the effect of terrain and wakes on the performance of the Bessaker wind farm. This 25 turbine wind farm is located in a highly complex terrain ... -
Lévy processes in term structure and market risk models
(Master thesis, 2020)Vi modellerer rentemarkeder med Lévy-terminstrukturmodeller generert av normal–inverse gaussiske (NIG) fordelinger og generaliserte hyperboliske skjeve Students (GSS) t-fordelinger. Vi sammenlikner modellene med en klassisk ... -
LIDAR Extended Object Tracking of a Maritime Vessel Using an Ellipsoidal Contour Model
(Master thesis, 2018)Extended object tracking (EOT) have numerous applications and can be integrated in autonomous systems like self-driving cars or autonomous surface vehicles. These systems can be improved by using robust tracking algorithms ... -
Lie group and exponential integrators: Theory, implementation, and applications
(Doctoral thesis, 2006)This PhD-thesis contains an introduction and six research papers sorted chronologically, of which the first four are accepted for publication. The introduction aims at giving a very brief summary of the background theory ... -
Lie Group Integrators for Cotangent Bundles of Lie Groups and Their Application to Systems of Dipolar Soft Spheres
(Master thesis, 2017)The objective of this thesis is to study numerical integrators and their application to solving ordinary differential equations arising from mechanical systems. Many mechanical problems are naturally formulated on Lie ... -
Lie Group integrators for mechanical systems
(Peer reviewed; Journal article, 2021)Since they were introduced in the 1990s, Lie group integrators have become a method of choice in many application areas. These include multibody dynamics, shape analysis, data science, image registration and biophysical ... -

Linear functions and duality on the infinite polytorus
(Journal article; Peer reviewed, 2019)We consider the following question: are there exponents 22 . Our approach is based on duality arguments and a detailed study of linear functions. Some related results are also presented. -
Linear Regression for Survey Data
(Bachelor thesis, 2020)Denne bacheloroppgaven er en del av emnet MA2002 på NTNU, som er 15 studiepoeng over ett semester. I denne oppgaven diskuterer vi hvordan man gjør linear regresjon når et komplekst utvalgsdesign er brukt for å samle inn ... -
Linear space properties of H^p spaces of Dirichlet series
(Journal article; Peer reviewed, 2019)We study H p spaces of Dirichlet series, called H p , for the range 0 < p < ∞. We begin by showing that two natural ways to define H p coincide. We then proceed to study some linear space properties of H p . More specifically, ... -
Linearization of Hénon maps and a polynomial automorphism with wandering Fatou components

Linearized Difference Networks as Approximate Kernel Methods
(Master thesis, 2019)I denne artikkelen studerer vi nevrale nettverk som tilnærminger til en relatert kjerne-metode (kernel method). Vi analyserer forutsigelsene gjort av et enkelt nevralt nettverk med et skjult lag. To kilder til varians i ... -
Linearly implicit local and global energy-preserving methods for Hamiltonian PDEs
(Journal article, 2019)We present linearly implicit methods that preserve discrete approximations to local and global energy conservation laws for multi-symplectic PDEs with cubic invariants. The methods are tested on the one-dimensional Korteweg–de ... -
Linearly implicit structure-preserving schemes for Hamiltonian systems
(Journal article, 2019)Kahan’s method and a two-step generalization of the discrete gradient method are both linearly implicit methods that can preserve a modified energy for Hamiltonian systems with a cubic Hamiltonian. These methods are here ... -
Lineær mikset modell for kompressor data med en applikasjon
(Master thesis, 2008)StatoilHydro is the operator of the Åsgard oil and gas field outside of Trøndelag, Norway, where large compressors for injection, recompression and export of natural gas are installed. The facility transports and stores ... -
Lineære hemmelige delingsprotokoller og sikre flerpartsberegninger
(Master thesis, 2014)Vi ser på lineære hemmelige delingsprotokoller og sikre flerpartsberegningsprotokoller. Shamirs hemmelige delingsprotokoll og en hemmelig delingsprotokoll basert på monotone utspenningsprogram blir presentert. Vi ser også ... -
The Liouville theorem and linear operators satisfying the maximum principle.
(Peer reviewed; Journal article, 2020)A result by Courrège says that linear translation invariant operators satisfy the maximum principle if and only if they are of the form L = Lσ,b + Lμ where Lσ,b[u](x) = tr(σσTD2u(x)) + b · Du(x) and Lμ[u](x) = Rd\{0} u(x ... -

A Lipschitz metric for the Camassa--Holm equation
(Peer reviewed; Journal article, 2020)We analyze stability of conservative solutions of the Cauchy problem on the line for the Camassa–Holm (CH) equation. Generically, the solutions of the CH equation develop singularities with steep gradients while preserving ...
