Varmtorsjonstesting av 3xxx-legeringer
(Master thesis, 2014)Styrkeeffekten av dispergerte partikler har blitt utforsket for en 3xxx-legering ved varmtorsjons-testing. Legeringens komposisjon var: 0,97wt.% Mn, 0,5wt.% Fe, 0,15wt.% Si og 0,05wt.% annet. Det er gjort fire forskjellige ... -
Varmtvannsirkulasjonssystemer som energibærer til lavtemperatur varmesystemer i leilighetsbygg, er det en lønnsom og akseptabel løsning?
(Bachelor thesis, 2019)Kort sammendrag Dagens vannbårne varmesystemer har vanligvis en lukket krets for varmeanlegg, og en krets for tappevann. Ettersom det blir jaktet på mer energi- og kostnadseffektive systemer har det også blitt aktuelt å ... -
The VAROS Synthetic Underwater Data Set: Towards realistic multi-sensor underwater data with ground truth
(Peer reviewed; Journal article, 2021)Underwater visual perception requires being able to deal with bad and rapidly varying illumination and with reduced visibility due to water turbidity. The verification of such algorithms is crucial for safe and efficient ... -

Varying disease-mediated selection at different life-history stages of Atlantic salmon in fresh water
(Journal article; Peer reviewed, 2011)Laboratory studies on associations between disease resistance and susceptibility and major histocompatibility (MH) genes in Atlantic salmon Salmo salar have shown the importance of immunogenetics in understanding the ... -
Varying Ignition Quality of a Fuel for a HCCI Engine Using a Photochemically-Controlled Additive: The Development of a ‘Smart’ Fuel
(Peer reviewed; Journal article, 2021)This study examines the possibility to provide control over ignition timing in a homogeneous charge compression ignition engine (HCCI) using a fuel additive whose molecular structure can be adapted upon exposure to UV ... -
Varying oxygen coverage on Cu55 and its effect on CO oxidation
(Journal article; Peer reviewed, 2019)Adsorption of molecular oxygen on a Cu55 cluster and the resulting oxidation effects have been investigated by spin-polarized density functional theory (DFT). The optimal structure for each Cu55O2N (N = 1–20) complex has ... -
Varying the forcing scale in low Prandtl number dynamos
