(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)According to the classical Archimedes’ principle, ice floats in water and has a fraction of its volume above the water surface. However, for very small ice particles, other competing forces such as van der Waals forces due ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Monocrystalline n-type zinc oxide (ZnO) samples prepared by different techniques and containing various amounts of lithium (Li) have been studied by positron annihilation spectroscopy (PAS) and secondary ion mass spectrometry. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Computation is a central aspect of 21st century physics practice; it is used to model complicated systems, to simulate impossible experiments, and to analyze mountains of data. Physics departments and their faculty are ...
-
(Master thesis / Masteroppgave, 2012)Denne masteravhandlingen tar for seg generell Bayesestimering og numerisk implementasjon for denne. Variablene og fordelingene er sett på i lys av navigasjonsterminologi. Tilstandene og observasjonene ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Discretized image signals might have a lower dynamic range than the display. Because of this, false contours might appear when the image has the same pixel value for a larger region and the distance between pixel levels ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Background: Iterative reconstruction techniques for reducing radiation dose and improving image quality in CT have proved to work differently for different patient sizes, dose levels, and anatomical areas. Purpose: This ...
