Statistiske metoder for analyse av data fra nasjonale prøver og undersøkelser i skoleverket.
(Master thesis, 2021)Nasjonale prøver ble for første gang gjennomført våren 2004. En forskningsbasert evaluering av prøvene i 2005 anbefalte sterkt en kraftig kompetanseheving på testteori og psykometri for de som utvikler og for de som leder ... -
Stochastic Epidemic Models on Complex Network
(Masteroppgave/UIS-HF-IMF/2019;, Master thesis, 2020-06-14)The spread of a virus or the outbreak of an epidemic are natural examples of stochastic processes. Classical mathematical descriptions of such phenomenon include various branching processes such as the SIR (Susceptible-I ... -
Stochastic gravitational wave background from stellar origin binary black holes in LISA
(Peer reviewed; Journal article, 2023)We use the latest constraints on the population of stellar origin binary black holes (SOBBH) from LIGO/Virgo/KAGRA (LVK) observations, to estimate the stochastic gravitational wave background (SGWB) they generate in the ... -
Stochastic inflation from quantum field theory and the parametric dependence of the effective noise amplitude
(Peer reviewed; Journal article, 2022-02)The non-linear dynamics of long-wavelength cosmological fluctuations may be phrased in terms of an effective classical, but stochastic evolution equation. The stochastic noise represents short-wavelength modes that continually ... -
Structure and morphology of CeO2 thin films from Raman spectroscopy and microscopic studies
(Master thesis, 2022)Cerium oxide has been subject of numerous studies because of its current and potential uses in supercapacitors, solar cells, self-cleaning glasses and in catalysis. Use of ceria in self-cleaning glass, especially on the ... -
A study of inhomogeneous massless scalar gauge fields in cosmology
(Peer reviewed; Journal article, 2022)Why is the Universe so homogeneous and isotropic? We summarize a general study of a γ-law perfect fluid alongside an inhomogeneous, massless scalar gauge field (with homogeneous gradient) in anisotropic spaces with General ... -
Study of Photochromic Effect in Yttrium Oxyhydride Films
(Master thesis, 2021)Mixed anion compounds have multiple different anions as part of their structure. Due to the different nature of individual anions the mixed anion compounds may exhibit other properties than the well known single anion ... -
Supernova constraints on dark flavored sectors
(Peer reviewed; Journal article, 2021-06)Proto-neutron stars forming a few seconds after core-collapse supernovae are hot and dense environments where hyperons can be efficiently produced by weak processes. By making use of various state-of-the-art supernova ... -
Survival Analysis using Cox Regression on Breast Cancer Data
(Master thesis, 2020-06)In this report, survival data from a german breast cancer study has been analysed using the programming software R. For the 686 female patients participating in the study, the value of eight explanatory variables were ... -
Symmetric teleparallel geometries
(Peer reviewed; Journal article, 2022)In teleparallel gravity and, in particular, in F(T) teleparallel gravity, there is a challenge in determining an appropriate (co-)frame and its corresponding spin connection to describe the geometry. Very often, the ‘proper’ ... -
Symmetry and Equivalence in Teleparallel Gravity
(Peer reviewed; Journal article, 2020-07)In theories such as teleparallel gravity and its extensions, the frame basis replaces the metric tensor as the primary object of study. A choice of coordinate system, frame basis, and spin-connection must be made to obtain ... -
Syntese og fotonedbrytningsevaluering av aminoalkoholer og oksazolidiner
(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 ... -
T3-invariant heterotic Hull-Strominger solutions
(Peer reviewed; Journal article, 2021-01)We consider the heterotic string on Calabi-Yau manifolds admitting a Strominger-Yau-Zaslow fibration. Upon reducing the system in the T3-directions, the Hermitian Yang-Mills conditions can then be reinterpreted as a complex ... -
Tales from Wonderland
(Doctoral thesis, 2020-06)Knowing that the Universe is quite isotropic, one may, as already discussed in Chapter 1, wonder how likely such a Universe is. We take the following research question. Question 1. Is the asymptotic future of a cosmology ... -
The card game SET and finite geometry
(Bachelor thesis, 2023)This thesis explores the underlying mathematics of the card game SET, which is a fast-paced pattern recognition game played with 81 cards. The game involves making SETs of three cards with certain compatibility conditions ... -

The dark matter freeze out and beyond
(Master thesis, 2022)Evidence of the existence of dark matter has been found due to deviations of gravitational motion of astronomical objects. We want to investigate the dark matter topic, which is constantly evolving due to the fast development ... -
The Fourier transform and its applications to partial differential equations.
(Master thesis, 2021)In this master’s thesis I will introduce a way to solve partial differential equations and boundary value problems by transforming signals from a time domain to a frequency domain, and back. This algorithm is ... -
The reasons for the collapse of the Tacoma Narrows Bridge and the lessons for the classroom
(Bachelor thesis, 2022)On 7 November 1940, a historical event occurred for suspension bridge construction and aerodynamic engineering around suspension bridges. Engineers investigating the event concluded the bridge collapsed due to high winds ... -
The Unicity of a Blow-down.
(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 ...
