Adaptive radiation therapy treatment for patients with locally advanced non-small cell lung cancer
(Master thesis, 2023-06-01)For locally advanced non-small cell lung cancer (LA-NSCLC) the current state-of-the-art treatment is intensity modulated radiation therapy (IMRT) using photons. Radiation therapy of LA-NSCLC can be challenging because of ... -
Adaptive transdure basert på tidsreversering. Målinger på en 5x5 array prototype
(Master thesis, 2009-06-11)Utvikling av adaptiv transduserarray som er ment for tidsreverserende bruk på en olje/gass-separator. Prinsippet består i styring av en transduser oppdelt i små ankeltceller (array). Hver celle styres av sin egen elektronikk, ... -
Adding pieces to the puzzle: insights into diversity and distribution patterns of Cumacea (Crustacea: Peracarida) from the deep North Atlantic to the Arctic Ocean
(Journal article; Peer reviewed, 2021)The Nordic Seas have one of the highest water-mass diversities in the world, yet large knowledge gaps exist in biodiversity structure and biogeographical distribution patterns of the deep macrobenthic fauna. This study ... -
Additive Schwarz preconditioner for the finite volume element discretization of symmetric elliptic problems
(Peer reviewed; Journal article, 2015-09-25)A symmetric and a nonsymmetric variant of the additive Schwarz preconditioner are proposed for the solution of a class of finite volume element discretization of the symmetric elliptic problem in two dimensions, with large ... -
Addressing class imbalance in deep learning for acoustic target classification
(Journal article; Peer reviewed, 2023)Acoustic surveys provide important data for fisheries management. During the surveys, ship-mounted echo sounders send acoustic signals into the water and measure the strength of the reflection, so-called backscatter. ... -
Addressing the hypertriton lifetime puzzle with ALICE at the LHC
(Peer reviewed; Journal article, 2019)The ALICE Collaboration collected a large data sample of Pb-Pb collisions at√sNN=5.02 TeV in 2015 at the LargeHadron Collider (LHC) and the excellent particle identification (PID) capabilities allow for the detection of ... -
Adferd som stressmål: Atlantisk laks under fluktuerende temperaturregime.
(Master thesis, 2013-07-09)SAMMENDRAG Stressresponser hos fisk blir tradisjonelt målt med parametre som kortisolkonsentrasjon og fôrkonsum som gir mål på stress og velferd. Det man mangler er gode mål på subtile stressreaksjoner og kunnskap om hvordan ... -
Adipose tissue fatty acids suggest spatial and temporal dietary differences in great cormorants of the Baltic Sea area
(Journal article; Peer reviewed, 2021)Increased numbers of great cormorants (Phalacrocorax carbo) in the Baltic Sea may have local impacts on fisheries and salmonid hatcheries. We studied spatial and temporal variability in cormorant diet, and potential ... -
Adjoint Modeling and Observing System Design in the Subpolar North Atlantic
(Doctoral thesis, 2019-08-30)The near-surface ocean currents of the subpolar North Atlantic transport large amounts of heat from the subtropics to higher latitudes, affecting Arctic sea ice extent, the melting of the Greenland Ice Sheet, and the climate ... -
Admissibility conditions for Riemann data in shallow water theory
(Journal article; Peer reviewed, 2020)Consideration is given to the shallow-water equations, a hyperbolic system modeling the propagation of long waves at the surface of an incompressible inviscible fluid of constant depth. It is well known that the solution ... -
Adsorption Behavior of Diclofenac on Polystyrene and Poly(butylene adipate-co-terephthalate) Microplastics: Influencing Factors and Adsorption Mechanism
