A Class of Tests for Trend in Time Censored Recurrent Event Data
(Journal article; Peer reviewed, 201904)Statistical tests for trend in recurrent event data not following a Poisson process are generally constructed for event censored data. However, time censored data are more frequently encountered in practice. In this paper ... 
Ab initio study: Investigating the adsorption behaviors of polarized greenhouse gas molecules on pillar[5]arenes
(Peer reviewed; Journal article, 2023)Supramolecular organic frameworks (SOFs) based on Pillar[5]arenes (P[5]A) have shown great potential in capturing and separating greenhouse gases. In this study, we investigate the adsorption behaviors of other environmentally ... 
Abinitio QCD Calculations Impact the Inference of the Neutronstarmatter Equation of State
(Peer reviewed; Journal article, 2023)We demonstrate that abinitio calculations in QCD at high densities offer significant and nontrivial information about the equation of state of matter in the cores of neutron stars, going beyond that which is obtainable ... 
Algebraens fundamentalteorem
(Bachelor thesis, 2021)Denne bacheloroppgaven tar utgangspunkt i Algebraens fundamentalteorem og polynomlikningens historie. Algebraens fundamentalteorem sier at hver polynomlikning av grad n med komplekse koeffisienter har minst én kompleks ...

An exploration of combinatorics and combinatorial geometry from a pedagogical perspective
(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 ... 
An introduction to differential forms and topological field theory
(Master thesis, 2022)In this thesis, we will use topological field theory to do an explicit computation of a oneloop partition function over a 6dimensional manifold. This is a topological invariant, which can be used to distinguish geometries. ... 
An Introduction to Supersymmetry
(Masteroppgave/UISTNIMF/2019;, Master thesis, 20190614)This thesis gives an introduction to supersymmetry. We compute the Poincaré conformal and Clifford algebra in any dimension. Most examples are in four dimensions, including the WessZumino model and supersymmetric gauge ... 
Analytic structure of nonhydrodynamic modes in kinetic theory
(Peer reviewed; Journal article, 201909)How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales ... 
Analyticity in Several Complex Variables
(Masteroppgave/UISTNIMF/2020;, Master thesis, 2020)there are many similarities between complex analysis in several variables and one variable but there are also some important differences between holomorphic functions of a single variable and holomorphic functions of $n$ ... 
Anomalous lowtemperature thermodynamics of QCD in strong magnetic fields
(Journal article; Peer reviewed, 201711)The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ... 
AnomalyInduced Inhomogeneous Phase in Quark Matter without the Sign Problem
(Peer reviewed; Journal article, 2019)We demonstrate the existence of an anomalyinduced inhomogeneous phase in a class of vectorlike gauge theories without the sign problem, thus disproving the longstanding conjecture that the absence of the sign problem ... 
Antimicrobial Resistance and the circular economy of water
(Master thesis, 2022)I takt med en økende global befolkning og en voksende industri, har utslippene av klimagasser økt, blir stadig større oppmerksomhet blitt rettet mot arbeidet for en mer bærekraftig fremtid. Verden har en stadig økende ... 
Application of 2D correlation Spectroscopy for Insitu Raman Data Analysis
(Master thesis, 2022) 
Atomic scattering factors and atomic crosssections in xray crystallography
(Masteroppgave/UISTNIMF/2018;, Master thesis, 20180615)Crystallographers as well as other scientists and engineers need reliable sets of physical data. Focus is here set upon the xray attenuation coefficients (the atomic photoeffect crosssection, and the incoherent (Compton) ... 
Bayesian inference of realtime dynamics from lattice QCD
(Peer reviewed; Journal article, 2022)The computation of dynamical properties of nuclear matter, ranging from parton distribution functions of nucleons and nuclei to transport properties in the quarkgluon plasma, constitutes a central goal of modern theoretical ... 
Bayesian seismic inversion for stratigraphic horizon, lithology, and fluid prediction
(Peer reviewed; Journal article, 2020)We have developed an efficient methodology for Bayesian prediction of lithology and pore fluid, and layerbounding horizons, in which we include and use spatial geologic prior knowledge such as vertical ordering of ... 
Bayesian uncertainty quantification of perturbative QCD input to the neutronstar equation of state
(Peer reviewed; Journal article, 2023)The equation of state of neutronstar 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 ... 
Beamforming anvendt på tauet antenne
(Bachelor thesis, 2022)I denne bacheloroppgaven har jeg skrevet om en ny generasjon tauet antenne med fokus på signalbehandlingen. Til å begynne med gjør jeg kort rede for signalbehandling i historisk sammenheng, og legger så fram problemstillingen. ...
