Multivariate DCC-GARCH Model: -With Various Error Distributions
(Master thesis, 2009)In this thesis we have studied the DCC-GARCH model with Gaussian, Student's $t$ and skew Student's t-distributed errors. For a basic understanding of the GARCH model, the univariate GARCH and multivariate GARCH models in ... -
The multivariate distributions of output streams in a queueing system with preemptive repeat priority
(Peer reviewed; Journal article, 2021)The paper studies a single server queuing system with r types of customers, preemptive repeat priority and an infinite number of positions in the queue. The arrival stream of customers of each type is a Poisson stream. Each ... -
Multivariate Distributions Through Pair-Copula Construction: Theory and Applications
(Master thesis, 2009)It is often very difficult, particularly in higher dimensions, to find a good multivariate model that describes both marginal behavior and dependence structure of data efficiently. The copula approach to multivariate models ... -
Multivariate Gaussian Random Fields: The Stochastic Partial Differential Equation approach
(Doctoral Theses at NTNU, 1503-8181; 2013:206, Doctoral thesis, 2013) -
Multivariate Hermite interpolation of manifold-valued data
(Journal article, 2024)In this paper, we propose two methods for multivariate Hermite interpolation of manifold-valued functions. On the one hand, we approach the problem via computing suitable weighted Riemannian barycenters. To satisfy the ... -
Multivariate log-concave probability density class for structural reliability applications
(Journal article; Peer reviewed, 2017)Structural reliability analysis is conventionally based on a description of uncertainty via a joint probability density function (JPDF). This paper builds on an alternative concept of working with a probability distribution ... -
Multivariate Periodic Wavelets on the Pattern
(Master thesis, 2023)I denne masteren analyserer me bilete og oppdagar kantar ved hjelp av fleirdimensjonale periodiske wavelets og fleirskala-analyse, på engelsk multiresolusion analysis. Me presanterer kongruensklassa til det $d$-variate ... -
Multivariate Public Key Cryptography
(Bachelor thesis, 2022)I denne oppgaven, så er målet å introdusere leseren til noen multivariate offentlig kryptografiske systemer. Vi vil gå gennom tre slike systemer. Disse systemene er Matsumoto Imai, Oil and Vinegar, og Rainbow. Vi vil gå ... -
Multivariate Quadratic Cryptosystems
(Master thesis, 2019)Vi beskriver egenskapene til multivariate ligningssystemer, og både egenskapene til Grøbnerbaser, og hvordan man beregner dem. Videre beskriver vi to multivariate kvadratiske kryptosystemer, kryptosystemet Matsumoto-Imai ... -
Multivariate Spatial Modeling using SPDEs with Application to Ocean Sampling
(Master thesis, 2022)I denne masteroppgaven vil vi foreslå multivariate romlige modeller for effektiv prediksjon av temperatur og salinitet i havet. Vi baserer modelleringen og analysen på modelløsninger fra en numerisk havmodell, SINMOD, ... -
Musical Source Separation using Diffusion Models
(Master thesis, 2023)Musikalsk kildeseparering er en utfordrende oppgave innen lydsignalbehandling som har som mål å ekstrahere individuelle kilder fra en musikalsk blanding, for eksempel å separere vokal fra bakgrunnsmusikk. I de siste årene ... -
Mutating signed -exceptional sequences
(Journal article; Peer reviewed, 2023)We establish some properties of τ -exceptional sequences for finite-dimensional algebras. In an earlier paper, we established a bijection between the set of ordered support τ -tilting modules and the set of complete ... -
n-cluster tilting subcategories for radical square zero algebras
(Peer reviewed; Journal article, 2023) -
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 ...
