(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)We propose novel modifications to an anomaly detection methodology based on multivariate signal reconstruction followed by residuals analysis. The reconstructions are made using Auto Associative Kernel Regression (AAKR), ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Adinkras are signed graphs used to study supersymmetry in physics. We provide an introduction to these objects, and study the properties of their signed adjacency and signed Laplacian matrices. These matrices each have ...

(Master thesis / Masteroppgave, 2015)Bølgeinduserte strømninger og bølgedempingsrater for ulike overflate-dekker er undersøkt ved hjelp av PIV og ultralydmålere. To økter med eksperimenter av mekanisk genererte monokromatiske bølger som forplanter seg i en ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)Lutefisk is a traditional Norwegian Christmas dish, made of dry cod soaked in a lye solution before re-hydrated. We report measurements of tissue rheological properties of cooked Lutefisk. Surprisingly, we find that the ...

(Doctoral thesis / Doktoravhandling, 2021)Thin viscous films are ubiquitous in Nature and biology and they are indispensable in industrial applications through lubrication and coating. In order to utilize the potential of thin viscous films on the micro and nano ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Constant potential methods (CPMs) enable computationally efficient simulations of the solid–liquid interface at conducting electrodes in molecular dynamics. They have been successfully used, for example, to realistically ...
-
(Research report / Forskningsrapport, 2009)The electrowetting process is commonly used to handle very small amounts of liquid on a solid surface. This process can be modelled mathematically with the help of the shape optimization theory. However, solving numerically ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)We prove that every circled domain in the Riemann sphere admits a proper holomorphic embedding into the affine plane C^2.
-
(Master thesis / Masteroppgave, 2021)In this thesis, we work with empirical likelihood functions and hybrid combinations of these with parametric likelihoods. We state and prove an analogue to Wilks theorem for the empirical likelihood function. In addition, ...

-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2013)Due to the non-storability of electricity and the resulting lack of arbitrage-based arguments to price electricity forward contracts, a significant time-varying risk premium is exhibited. Using EEX data during the introduction ...

-
En empirisk studie av kumulative insidensfunksjoner estimert ved Cox regresjon og Fine-Gray metoden (Master thesis / Masteroppgave, 2013)I denne oppgaven studerer og sammenligner vi to modeller for konkurrerende dødsårsaker; Cox proporsjonale modell for de årsaksspesifikke hasardratene (Cox 1972) og proporsjonal subfordelingsmodell(Fine & Gray 1999). For ...
-
(Master thesis / Masteroppgave, 2017)Målet ved denne artikkelen er å analysere forholdet mellom vri- og flyttespill og symmetrigruppen. Vi skal se sammenhengen mellom gruppeteori og mange populære spill, spesielt når man vil løse spillene
-
(Master thesis / Masteroppgave, 2023)Astrocytes play an important part in the central nervous system, but their role and structure are not yet fully understood. Previous studies of cultured astrocytes and astrocytes in brain slices have concluded that the ...
