Including New Customers in The Prediction of Electricity Consumption
(Master thesis, 2023)Det er avgjerande for bedrifter som kjøper straum på førehand å oppnå nøyaktige prognosar for forbruket. Ved å nytte maskinlæring og historiske data kan ein utvikle prediktive responssmodellar. Hovudmålet med masteroppgåva ... -
Bi-parameter Potential theory and Carleson measures for the Dirichlet space on the bidisc

On the Catlin Multitype of Sums of Squares Domains
(Journal article; Peer reviewed, 2022)For a sum of squares domain of finite D’Angelo 1-type at the origin, we show that the polynomial model obtained from the computation of the Catlin multitype at the origin of such a domain is likewise a sum of squares domain. ... -
Two-variable fibrations, factorisation systems and -categories of spans
(Peer reviewed; Journal article, 2023)We prove a universal property for ∞-categories of spans in the generality of Barwick’s adequate triples, explicitly describe the cocartesian fibration corresponding to the span functor, and show that the latter restricts ... -
Landwebers exact functor theorem
(Bachelor thesis, 2023)Når man jobber med algebraisk topologi bruker man mange invarianter. De er veldig viktige i fagfeltet. En slik invariant er kohomologi. Disse invariantene tar inn topologiske rom og sender ut abelske grupper. Med en passende ... -

Dynamic learning spaces—dynamic pedagogy. Students’ voices from a master’s program focusing on student active learning in a cross-institution two-campus organization
(Peer reviewed; Journal article, 2023)These past few years have shown the importance of successfully designing cross-campus and multi-campus hybrid and fully digital learning environments to sustain and guarantee continuity in learners’ higher education - an ... -
B-stability of numerical integrators on Riemannian manifolds
(Peer reviewed; Journal article, 2024)We propose a generalization of nonlinear stability of numerical one-step integrators to Riemannian manifolds in the spirit of Butcher's notion of B-stability. Taking inspiration from Simpson-Porco and Bullo, we introduce ... -

Faktorisering av idealar i Dedekindområder
(Bachelor thesis, 2023)I denne bacheloroppgåva studerer ein korleis ideal blir faktorisert til eit unikt produkt av primideal i eit Dedekindområde. Det er interessant at ideal har denne eigenskapen, sidan det ikkje nødvendigvis er slik at eit ... -
Lattice-Based Authenticated Key Exchange with Tight Security
(Peer reviewed; Journal article, 2023)We construct the first tightly secure authenticated key exchange (AKE) protocol from lattices. Known tight constructions are all based on Diffie-Hellman-like assumptions. Thus, our protocol is the first construction with ... -
Recommendations for quantitative uncertainty consideration in ecology and evolution
(Peer reviewed; Journal article, 2023)Ecological and evolutionary studies are currently failing to achieve complete and consistent reporting of model-related uncertainty. We identify three key barriers – a focus on parameter-related uncertainty, obscure ... -
Manifolds.jl: An Extensible Julia Framework for Data Analysis on Manifolds
(Peer reviewed; Journal article, 2023)We present the Julia package Manifolds.jl, providing a fast and easy-to-use library of Riemannian manifolds and Lie groups. This package enables working with data defined on a Riemannian manifold, such as the circle, the ... -
A Generic Construction of Tightly Secure Password-Based Authenticated Key Exchange
(Peer reviewed; Journal article, 2023)We propose a generic construction of password-based authenticated key exchange (PAKE) from key encapsulation mechanisms (KEM). Assuming that the KEM is oneway secure against plaintext-checkable attacks (OW-PCA), we prove ... -
Derived equivalence classification techniques for Nakayama algebras
(Doctoral theses at NTNU;2024:18, Doctoral thesis, 2024)In the representation theory of finite dimensional algebras, the fundamental goal is to understand the structure of the category mod⇤ of finite dimensional modules over an algebra ⇤. While solving this problem is difficult ... -
One-sided Hölder regularity of global weak solutions of negative order dispersive equations
(Peer reviewed; Journal article, 2023)We prove global existence, uniqueness and stability of entropy solutions with initial data for a general family of negative order dispersive equations. These weak solutions are found to satisfy one-sided Hölder conditions ... -
Analytical and numerical solutions of radially symmetric aquifer thermal energy storage problems
(Peer reviewed; Journal article, 2023)Aquifer thermal energy storage (ATES) systems offer reduced energy costs, lower carbon emissions, and increased energy resilience. The feasibility, however, depends on several factors and usually require optimization. We ... -
