  • Identification of the flux function of nonlinear conservation laws with variable parameters 

    Li, Qing; Geng, Jiahui; Evje, Steinar (Peer reviewed; Journal article, 2023-09)
    Machine learning methods have in various ways emerged as a useful tool for modeling the dynamics of physical systems in the context of partial differential equations (PDEs). Nonlinear conservation laws (NCLs) of the form ...
  • A new variational discretization technique for initial value problems bypassing governing equations 

    Rothkopf, Alexander Karl; Nordström, Jan (Peer reviewed; Journal article, 2023-03)
    Motivated by the fact that both the classical and quantum description of nature rest on causality and a variational principle, we develop a novel and highly versatile discretization prescription for classical initial value ...
  • Real-Time Complex Langevin - A Differential Programming Perspective 

    Alvestad, Daniel (PhD thesis UiS;, Doctoral thesis, 2023)
    In this thesis, I aim to find solutions to the NP-hard sign-problem that arises when modeling strongly correlated systems in real-time. I will use the complex Langevin (CLE) method, and address its problem of runaway ...
  • Can cancer cells inform us about the tumor microenvironment? 

    Nævdal, Geir; Evje, Steinar (Peer reviewed; Journal article, 2023)
    Characteristics of the tumor microenvironment (TME) such as the leaky intratumoral vascular network and the density and composition of the desmoplastic extracellular matrix (ECM) contain essential information that determine ...
  • Mathematical and Numerical Aspects of Scalar Nonlinear Conservation Laws 

    Bhatti, Farrukh Abbas (Master thesis, 2023)
    This thesis delves deeply into numerical solutions to nonlinear conservation laws. It focuses largely on the Method of Characteristics, its application in solving conservation laws, and the implementation of solutions in ...
  • The Unicity of a Blow-down. 

    Zimba Omega (Master thesis, 2023)
    In algebraic geometry, projective varieties are classified up to isomorphism. This involves classifying the varieties up to birational equivalence and classifying nonsingular varieties in each equivalence class up to ...
  • Bayesian uncertainty quantification of perturbative QCD input to the neutron-star equation of state 

    Gorda, Tyler; Komoltsev, Oleg; Kurkela, Eero Aleksi; Mazeliauskas, Aleksas (Peer reviewed; Journal article, 2023)
    The equation of state of neutron-star cores can be constrained by requiring a consistent connection to the perturbative Quantum Chromodynamics (QCD) calculations at high densities. The constraining power of the QCD input ...
  • Learning the nonlinear flux function of a hidden scalar conservation law from data 

    Li, Qing; Evje, Steinar (Peer reviewed; Journal article, 2023-10)
    Nonlinear conservation laws are widely used in fluid mechanics, biology, physics, and chemical engineering. However, deriving such nonlinear conservation laws is a significant and challenging problem. A possible attractive ...
  • Dybdelæring og tverrfaglighet 

    Østebø, Marlene Seljeskog; Urianstad, Simen Bugge (Master thesis, 2023)
    Da ny læreplan av 2020 ble introdusert, var det spesielt et begrep som stod i fokus - dybdelæring. Hvor tidligere læreplan ønsket at elevene skulle kunne utføre oppgaver gjennom en instrumentell forståelse, skulle elevene ...
  • New benchmarks in the modelling of X-ray atomic form factors 

    Thorkildsen, Gunnar (Peer reviewed; Journal article, 2023)
    Analytical representations of X-ray atomic form factor data have been determined. The original data, f0(s;Z), are reproduced to a high degree of accuracy. The mean absolute errors calculated for all s = sin θ/λ and Z values ...
  • Syntese og fotonedbrytningsevaluering av aminoalkoholer og oksazolidiner 

    Zeynep Mersin (Master thesis, 2023)
    Synteseforskning på etanolaminer og deres derivater, oksazolidiner, representerer bare en del av den større innsatsen for å bekjempe antibiotikaresistens og utvikle nye strategier for behandling. Antibiotikaresistens er ...
  • Modified Kerr and Black Hole Ringdowns 

    Ahmed, Zaryab (Master thesis, 2023)
    In the post-merger phase of a black hole binary system, the remnant object is a perturbed black hole emitting gravitational radiation in the form of Gravitational Waves (quasi-normal modes) before admitting a stable state. ...
  • Harmonic Phonon Transport in Strontium Titanate: experiment vs computation 

    Gill, Shibl (Master thesis, 2023)
    Thermoelectric materials can be a boon for the temperature regulation industry, however, before its popular use as a green energy management solution, it is imperative that we uncover thermal transport in these materials. ...

    Chisamanga Beatrice (Master thesis, 2023)
    This thesis has undertaken the task of clearly defining the full heterotic moduli space for E_8 x E_8 heterotic string theory in standard embedding while utilizing the mathematical tools offered by the deformation theory ...
  • Transversality, Intersection Theory and Sheaf Theory 

    Rørhus Flaate, Kristoffer (Master thesis, 2023)
    In this thesis we present the theory of transversality and intersection theory on manifolds. Thereafter we present the theory of sheaves with the goal of using sheaf theory on manifolds together with intersection theory ...
  • Non-equilibrium quantum field dynamics in the early Universe 

    Eriksson, Magdalena (PhD thesis UiS;, Doctoral thesis, 2023)
    Inflation is the leading paradigm of early Universe cosmology. It provides compelling explanations of the observed near-homogeneity of the cosmic microwave background (CMB) radiation, the spatial flatness of the Universe ...
  • Dybdelæring i matematikk 

    Serigstad, Adrian (Master thesis, 2023)
    This study examines deep learning in mathematics and investigates whether a focus on deep learning can lead to deep understanding of a mathematical topic. Deep learning proves to be a diverse concept with various interpretations ...
  • An exploration of combinatorics and combinatorial geometry from a pedagogical perspective 

    Finnestad, Hanne (Master thesis, 2023)
    This thesis explores combinatorics and combinatorial geometry and how it can be used in the classroom, with a particular focus on using these sorts of tasks with younger students. There are 4 different types of combinations ...
