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 ... -

Local Analysis of Ocean Wave Measurements
(Master thesis, 2007)This master thesis investigates the Short Time Fourier transform and the Continuous Wavelet transform in relation to a directional analysis of in situ ocean wave measurements. We have determined the statistical properties ... -
Local Class Field Theory via Lubin-Tate Formal Groups
(Bachelor thesis, 2023)Oppgaven tar for seg lokal klassekroppsteori via Lubin-Tate teori. Vi viser lokal samsvarighet, basebytte og eksistens for Lubin-Tate utvidelser. -
Local Gorenstein duality for cochains on spaces
(Peer reviewed; Journal article, 2021)We investigate when a commutative ring spectrum R satisfies a homotopical version of local Gorenstein duality, extending the notion previously studied by Greenlees. In order to do this, we prove an ascent theorem for local ... -
Logistic Mixed Models for Demographic and Health Indicators
(Master thesis, 2021)Nyfødtdødelighet og vaksinedekning mot meslinger er viktige helseindikatorer for en nasjon. Demographic and Health Surveys (DHS) er en pålitelig kilde for å spore indikatorer for å forbedre en nasjons helse i lav- og ... -
Long-Horizon Informative Path Planning with Obstacles and Time Constraints
(Peer reviewed; Journal article, 2022)We apply non-myopic informative path planning in a simulated river plume case study with several constraints on our agent. A cost valley philosophy is proposed to guide the agent through the field. The purpose of this path ... -
Long-term extreme response and reliability of a vessel rolling in random beam seas
(Journal article; Peer reviewed, 2018)In this paper, the long-term extreme response of a vessel rolling in random beam seas and the associated reliability evaluation are addressed. The long-term response analysis is based on the upcrossing rates of the roll ... -
Long-term shifts in water quality show scale-dependent bioindicator responses across Russia – Insights from 40 year-long bioindicator monitoring program
(Peer reviewed; Journal article, 2019)Scale-related assessment strategies are important contributions to successful ecosystem management. With varying impact of environmental drivers from local to regional scales, a focal task is to understand scale-dependent ... -
Long-term variation in numbers and biomass of silver eels being produced in two European river systems
(Journal article; Peer reviewed, 2018)The European eel (Anguilla anguilla) population has been in decline at least since the 1960s and reliable regional information, particularly on the spawner production and escapement (i.e. the silver eel life stage), is a ... -
Low serum lipocalin-2 in pregnant women with systemic lupus erythematosus
(Peer reviewed; Journal article, 2023)OBJECTIVES: Systemic lupus erythematosus (SLE) pregnancies are considered high-risk due to risk of disease flare and pregnancy complications. A more in-depth understanding of the immunological alterations in SLE patients ... -
Lower survival probability of house sparrows severely infected by the gapeworm parasite
(Journal article; Peer reviewed, 2014)The effect of parasites in natural populations has received increasing attention in recent years. Studies have shown that parasites may play an important part in population ecology due to their potential effects on host ...
