«Open Middle Math», dybdelæring & positive holdninger i matematikk
(Masteroppgave/UIS-HF-IMF/2020;, Master thesis, 2019-07)Som både lektorstudent og deltidsarbeidene i videregående skole er det mye fokus på hvordan lærere skal forberede seg i møte med fagfornyelsen. Dybdelæring er et sentralt begrep i fagfornyelsen. Motivasjonen for denne ... -
Open-quantum-systems approach to in-medium heavy quarkonium dynamics
(Peer reviewed; Journal article, 2023)Heavy quarkonium continues to play a central role in the study of nuclear matter under extremes of temperature and density in relativistic heavy-ion collisions. In this talk I report on recent developments in the theoretical ... -
Optimisation of Thimble simulations and quantum dynamics of multiple fields in real time
(Peer reviewed; Journal article, 2022)We apply the Generalised Thimble approach to the computation of exact path integrals and correlators in real-time quantum field theory. We first investigate the details of the numerical implementation and ways of optimizing ... -
Order parameter dynamics of the non-linear sigma model in the large N limit
(Peer reviewed; Journal article, 2020)We study non-equilibrium order parameter dynamics of the non-linear sigma model in the large N limit, using Keldysh formalism. We provide a scheme for obtaining stable numerical solution of the Keldysh saddle point equations ... -
Overall and relative Survival for Cancer Patients
(Masteroppgave/UIS-TN-IMF/2019;, Master thesis, 2019-06)In this thesis, basic concepts of survival analysis such as censoring, truncation and survival functions are described. Measures of survival ( i.e overall survival, net survival and relative survival ratio) and ... -
Paradokser i sannsynlighetsregning og statistikk, og bruk av disse i undervisningssammenheng
(Master thesis, 2023)I denne oppgaven presenteres ulike paradokser innenfor sannsynlighetsregning og statistikk. Et paradoks er en påstand som er sann, men som virker absurd eller selvmotsigende. Vi kan møte på mange typer paradokser i ... -
Perturbative thermal QCD: Formalism and applications
(Peer reviewed; Journal article, 2020)In this review article, we discuss the current status and future prospects of perturbation theory as a means of studying the equilibrium thermodynamic and near-equilibrium transport properties of deconfined QCD matter. We ... -
PHYSICAL PROPERTIES OF THE 1D MAGNET β- VOSO4
(Master thesis, 2021)In this work the β phase of Vanadiumoxosulphate (VI) (β −V OSO4) crystal was used to study the physical properties of low dimensional magnetism in spin ½ chains. Structural analysis from X-ray diffraction and neutron ... -
Pion condensation and phase diagram in the Polyakov-loop quark-meson model
(Journal article; Peer reviewed, 2018-10)We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study the phase diagram in the μI–T planewhere μI is the isospin chemical potential. In particular, we focus on the ... -
Pion condensation and QCD phase diagram at finite isospin density
(Journal article; Peer reviewed, 2019-09)We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study 1) the possibility of inhomogeneous chiral condensates and its competition with a homogeneous pion condensate ... -
Poncelet's Theorem
(Masteroppgave/UIS-TN-IMF/2018;, Master thesis, 2018-10)This thesis will be concerned with different questions related to the theorem of Poncelet. We will study the historical background of the theorem and learn theory needed to understand two different proofs. -
Porous flow with diffuse interfaces
(Chapter, 2021)This chapter presents a model developed by the author, in publications dated from 2002 to 2016, on flow in porous media assuming diffuse interfaces. It contains five sections. Section 1 is an Introduction, tracing the ... -
PRECISE COMPUTATION OF MODULI SPACE FOR STANDARD EMBEDDING.
(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 ... -
Predicting parton energy loss in small collision systems
(Peer reviewed; Journal article, 2021)Medium induced parton energy loss is not conclusively established either in very peripheral heavy-ion collisions or in proton-ion collisions. However, the standard interpretation of azimuthal momentum anisotropies in these ... -
Prevalence of bradycardia in 4876 newborns in the first minute after birth and association with positive pressure ventilation: A population-based cross-sectional study
(Peer reviewed; Journal article, 2023)Objective To determine the prevalence of bradycardia in the first minute after birth and association with positive pressure ventilation (PPV). Method A population-based cross-sectional study was conducted from June 2019 ... -
Proper static potential in classical lattice gauge theory at finite T
(Peer reviewed; Journal article, 2021)We compute the proper real-time interaction potential between a static quark and antiquark in classical lattice gauge theory at finite temperature. Our central result is the determination of the screened real-part of this ... -
