GRACE-derived ice-mass loss spread over Greenland
(Peer reviewed; Journal article, 2015)The Gravity Recovery and Climate Experiment (GRACE) monthly satellite data is used to examine the extent and magnitude of Greenland ice sheet melting for 2003-2012. We show that the well documented Greenland ice mass loss ... -
Graceful Ageing of Products
(Master thesis, 2020)Products, regardless of their utility, face the challenge of time. Whether it is through wear and tear, changes in personal and societal values, or incompatibility with unforeseen technological advancement, very few designs ... -
Graded readers: An intralingual translation case study
(Bachelor thesis, 2020)Denne oppgaven tar for seg intralingual oversettelse gjennom analyse av en gradert (lettlest) lesebok. Kildeteksten er Matilda av Roald Dahl og målteksten er en versjon av teksten som er monospråklig oversatt for det formål ... -
Graded-material design based on phase-field and topology optimization
(Journal article; Peer reviewed, 2019)In the present work we introduce a novel graded-material design based on phase-field and topology optimization. The main novelty of this work comes from the introduction of an additional phase-field variable in the classical ... -
Gradert sykemelding : positivt eller negativt press for å få flere i arbeid? : en studie av hvordan sykemeldte opplever å være i gradert arbeid
(Master thesis, 2016)Det har lenge blitt arbeidet med å få ned sykefraværet i Norge, og graderte sykmeldinger er en strategi som har blitt brukt og som brukes i stadig større grad i det arbeidet. Det er et tiltak som skal få ned det totale ... -
Gradient Based Design Optimization of a Radial Inflow Turbine
(Chapter, 2020)The expander is one of the key components of an ORC as the cycle efficiency strongly depends on the expander efficiency. This paper presents a method for design optimization of a radial inflow turbine (RIT) using a mean-line ... -
Gradient based optimization of Permanent Magnet generator design for a tidal turbine
(Chapter, 2014)An optimization of an analytical problem with nine variables is executed to find the optimal Permanent Magnet(PM) generator for a tidal turbine. A gradient based solver is used to find the minimum cost of active materials ... -
The gradient flow of infinity-harmonic potentials
(Peer reviewed; Journal article, 2021)We study the streamlines of ∞-harmonic functions in planar convex rings. We include convex polygons. The points where streamlines can meet are characterized: they lie on certain curves. The gradient has constant norm along ... -
Gradient in defect density of ZnO nanorods grown by cathodic delamination, a corrosion process, leads to end-specific luminescence
(Journal article; Peer reviewed, 2018)ZnO nanorods were grown on a zinc substrate via cathodic delamination of a polymer coating, a tailored corrosion process, at room temperature. A comparison between in situ Raman spectra and post mortem cross sectional ... -
