(Master thesis / Masteroppgave, 2017)The estimation of inverse covariance matrices plays a major role in portfolio optimization, for the global minimum variance portfolio in mean-variance analysis it is the only parameter used to determine the asset allocation. ...
-
(Doctoral thesis / Doktoravhandling, 2023)Most forms of dementia, including Alzheimer’s, are incurable and their causes are not properly understood. In recent years, it has been suggested that the cerebrospinal fluid, a water-like fluid that surrounds the brain, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We study the reciprocal variety to the LSSM of catalecticant matrices associated with ternary quartics. With numerical tools, we obtain 85 to be its degree and 36 to be the ML-degree of the LSSM. We provide a geometric ...

Investigating molecular transport in the human brain from MRI with physics-informed neural networks (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract In recent years, a plethora of methods combining neural networks and partial differential equations have been developed. A widely known example are physics-informed neural networks, which solve problems involving ...

(Master thesis / Masteroppgave, 2016)Brain aneurysms are focalized diseased blood vessels, often shaped like a balloon, which can rupture and cause bleeding in the brain. The presence of aneurysms is correlated with internal carotid artery (ICA) extracranial ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)This study presents an experimental investigation of plunging breakers on a sloping beach with an inclination of 5.1°. The incident waves are solitary waves with various amplitudes from non-breaking waves to plunging ...
-
(Master thesis / Masteroppgave, 2015)Resonant behaviour in the gap between two adjacent bodies on a free surface is investigated numerically. The study is done within the framework of two-dimensional potential theory. It is of common conception that traditional ...
-
(Master thesis / Masteroppgave, 2018)Cancer is a major public health problem worldwide where it is the second leading cause of death. To improve safety and efficacy of anti-cancer drugs with less side effects, nanoparticles (NPs) have been studied heavily. ...
-
(Master thesis / Masteroppgave, 2015)One of the challenges related to modelling calcium dynamics in cardiac cells is the large difference in the length scales involved. The dyad, where important processes take place, is very small compared to the whole cell. ...
