Naive motivic homotopy classes of endomorphisms of the projective line
(Master thesis, 2020)Vi studerer naive motiviske homotopiklasser av endomorfier av den projektive linja over en kropp. Først redegjør vi for Cazanaves resultat om at den kanoniske funksjonen fra naive til motiviske homotopiklasser er en ... -
Naive-commutative structure on rational equivariant K-theory for abelian groups
(Peer reviewed; Journal article, 2022)In this paper, we calculate the image of the connective and periodic rational equivariant complex K-theory spectrum in the algebraic model for naive-commutative ring G-spectra given by Barnes, Greenlees and Kędziorek for ... -
Native range estimates for red-listed vascular plants
(Peer reviewed; Journal article, 2022)Besides being central for understanding both global biodiversity patterns and associated anthropogenic impacts, species range maps are currently only available for a small subset of global biodiversity. Here, we provide a ... -
Near wake region of an industrial scale wind turbine: comparing LES-ALM with LES-SMI simulations using data mining (POD)
(Journal article, 2017)Accurate prediction of power generation capability needs proper assessment of blade loading and wake behavior. In this regard, the Sliding Mesh Interface (SMI) approach and the Actuator Line Model (ALM) are two diverse ... -
Nedre Otta kraftverk. Utredning av konsekvenser for harr, ørret og bunndyr i influensområdet
(NINA rapport;621, Research report, 2011)Bakgrunn: I januar 2009 sendte AS Eidefoss og Opplandskraft DA melding om Nedre Otta kraftverk ut på høring. Det er beskrevet to utbyggingsalternativer i meldinga. Alternativet ”Pillarguri” vil utnytte fallet mellom inntaket ... -
The Nehari problem for the Paley--Wiener space of a disc
(Peer reviewed; Journal article, 2023)There is a bounded Hankel operator on the Paley–Wiener space of a disc in R2 which does not arise from a bounded symbol. -
Nehari’s theorem for convex domain Hankel and Toeplitz operators in several variables
(Peer reviewed; Journal article, 2021)We prove Nehari’s theorem for integral Hankel and Toeplitz operators on simple convex polytopes in several variables. A special case of the theorem, generalizing the boundedness criterion of the Hankel and Toeplitz operators ... -
Nerveteoremet i det endelege, kompakte og konvekse tilfellet i ℝⁿ
(Bachelor thesis, 2022)Topologisk dataanalyse er eit fagfelt der ein brukar abstrakte topologiske verktøy til å rekna seg fram til «forma» til data, og i denne teksten så viser eg eit sentralt teorem i topologisk dataanalyse, kalla for ... -
A nested multi-scale model for assessing urban wind conditions : Comparison of Large Eddy Simulation versus RANS turbulence models when operating at the finest scale of the nesting
(Journal article; Peer reviewed, 2021)Good understanding of micro-scale urban-wind phenomena is needed for optimizing power generation capabilities of building-integrated wind turbines and for safety of futuristic urban transport involving drones. The current ... -
Neural networks in Fréchet spaces
(Peer reviewed; Journal article, 2022)We propose a neural network architecture in infinite dimensional spaces for which we can show the universal approximation property. Indeed, we derive approximation results for continuous functions from a Fréchet space X ... -
Neural Networks on Low-Rank and Stiefel Manifolds
(Master thesis, 2022)I denne oppgaven ser vi på effekten av dyp læring som optimal kontroll på mangfoldigheter. Vi utvikler og trener flere nettverk som bevarer lav-rang og ortogonalitet i treningsprosessen. Bibetingelsen til optimal kontroll ... -
New tests for trend in time censored recurrent event data
(Journal article; Peer reviewed, 2024)We consider testing for trend in recurrent event data. More precisely, for such data we consider testing of the null hypothesis of data coming from a renewal process. The new tests are essentially obtained by considering ... -
Newtons metode for komplekse polynomer: Hvordan finne røttene på en effektiv måte?
(Master thesis, 2010)Oppgaven omhandler bruk av Newtons metode på komplekse polynomer. Det gis et resultat som sier hvor mange startpunkter man trenger for å finne alle røttene til et polynom av grad d. Det gis også en øvre grense for hvor ... -

Next Generation Multiscale Methods for Reservoir Simulation
(Doctoral theses at NTNU;2016:374, Doctoral thesis, 2016)In this thesis, we discuss multiscale simulation techniques for flow and transport in porous media, discretized on unstructured grids. The model equations considered are taken from the field of reservoir simulation, where ... -
NIME Prototyping in Teams: A Participatory Approach to Teaching Physical Computing
(Chapter, 2019)In this paper, we present a workshop of physical computing applied to NIME design based on science, technology, engineering, arts, and mathematics (STEAM) education. The workshop is designed for master students with ... -
Nodal Geometry and Growth of Solutions to Elliptic Partial Differential Equations
(Doctoral theses at NTNU;2022:216, Doctoral thesis, 2022)In this thesis we will study zeros and growth properties of solutions to elliptic PDEs. In particular, we first study zeros of linear combination of Laplace-Beltrami eigenfunctions via a growth estimate for positive solutions ... -
Noise removal in synthetically generated diffusion tensor imaging data using a denoising autoencoder
(Bachelor thesis, 2020)Diffusjonstensor avbildning (DTI) er en populær medisinsk avbildningsteknikk som kartlegger diffusjonen av vannmolekyler i biologisk vev. Målte DTI-data er forurenset av støy, og temaet for dette prosjektet var å utforske ... -
Noise-driven bifurcations in a neural field system modelling networks of grid cells
(Peer reviewed; Journal article, 2022)The activity generated by an ensemble of neurons is affected by various noise sources. It is a well-recognised challenge to understand the effects of noise on the stability of such networks. We demonstrate that the patterns ...
