Kernelization of Graph Hamiltonicity: Proper H-Graphs
(Journal article; Peer reviewed, 2021)We obtain new polynomial kernels and compression algorithms for Path Cover and Cycle Cover, the well-known generalizations of the classical Hamiltonian Path and Hamiltonian Cycle problems. Our choice of parameterization ... -
Kernelization of Vertex Cover by Structural Parameters
(Master thesis, 2015-08-03)In the NP-complete problem Vertex Cover, one is given a graph G and an integer k and are asked whether there exists a vertex set S ⊆ V (G) with size at most k such that every edge of the graph is incident to a vertex in ... -
Kernelization of Whitney Switches
(Journal article; Peer reviewed, 2020)A fundamental theorem of Whitney from 1933 asserts that 2-connected graphs G and H are 2-isomorphic, or equivalently, their cycle matroids are isomorphic, if and only if G can be transformed into H by a series of operations ... -
Kernelization of Whitney Switches
(Journal article; Peer reviewed, 2021)A fundamental theorem of Whitney from 1933 asserts that 2-connected graphs $G$ and $H$ are 2-isomorphic, or equivalently, their cycle matroids are isomorphic if and only if $G$ can be transformed into $H$ by a series of ... -
Kernels of digraphs with finitely many ends
(Journal article; Peer reviewed, 2019)According to Richardson’s theorem, every digraph without directed odd cycles that is either (a) locally finite or (b) rayless has a kernel (an independent subset with an incoming edge from every vertex in ). We generalize ... -
Key physical processes and their model representation for projecting climate impacts on subarctic Atlantic net primary production: A synthesis
(Journal article; Peer reviewed, 2023)Oceanic net primary production forms the foundation of marine ecosystems. Understanding the impact of climate change on primary production is therefore critical and we rely on Earth System Models to project future changes. ... -
Key Role of the Ocean Western Boundary currents in shaping the Northern Hemisphere climate
(Peer reviewed; Journal article, 2019)The individual impact of North Atlantic and Pacific Ocean Western Boundary Currents (OWBCs) on the tropospheric circulation has recently been studied in depth. However, their simultaneous role in shaping the hemisphere-scale ... -
The key role of topography in altering North Atlantic atmospheric circulation during the last glacial period
(Peer reviewed; Journal article, 2011-10-18)The Last Glacial Maximum (LGM; 21 000 yr before present) was a period of low atmospheric greenhouse gas concentrations, when vast ice sheets covered large parts of North America and Europe. Paleoclimate reconstructions and ... -
Kinase chemodiversity from the Arctic: the breitfussins
(Peer reviewed; Journal article, 2019)In this work, we demonstrate that the indole-oxazole-pyrrole framework of the breitfussin family of natural products is a promising scaffold for kinase inhibition. Six new halogenated natural products, breitfussin C–H (3 ... -
Kinetic description of particle emission from expanding source
(Peer reviewed; Journal article, 2008-05-22)The freeze out of the expanding systems, created in relativistic heavy ion collisions, is discussed. We combine kinetic freeze out equations with Bjorken type system expansion into a unified model. The important feature ... -
Kinetic Equation for an Electron Gas (Non-Neutral Plasma) in Strong Fields and Inhomogenities

Kinetic model of resonant nanoantennas in polymer for laser induced fusion
(Journal article; Peer reviewed, 2023)Studies of resilience of light-resonant nanoantennas in vacuum are extended to consider the case of polymer embedding. This modifies the nanoantenna’s lifetime and resonant laser pulse energy absorption. The effective ... -
Kinetic Theory for Evolution of a Plasma in External Electromagnetic Fields toward a State characterized by Balance of Forces Transverse to the Magnetic Field
(Department of Applied Mathematics report, Research report, 1973-04) -
Kjemiske bindinger i kjemilærebøker: En kvalitativ studie som sammenligner de nye lærebøkene i Kjemi 1 etter LK20
(Master thesis, 2022-06-01)Denne oppgaven er en lærebokanalyse av dagens lærebøker i Kjemi 1, og ser spesielt etter hvordan kjemiske bindinger og dybdelæring kommer til uttrykk i disse bøkene. Nylig har det kommet ut en ny læreplan i kjemi. Det er ... -
Kjennetegn på elevers teorifokuserte dialoger under praktiske aktiviteter i naturfagsundervisning
(Master thesis, 2018-06-20)Overordnet tema for oppgaven er dialog, der fokus ligger på dialog mellom elever uten lærerveiledning. Muntlige ferdigheter er en grunnleggende ferdighet som skal inngå i alle skolens fag, inkludert naturfag (Utdanningsd ... -
Kjennetegn på kritisk tenkning hos elever i et utforskende eksperiment i fysikk
(Master thesis, 2021-06-09)I Fagfornyelsen står det at «fysikk skal bidra til at elevene utvikler en vitenskapelig og kritisk tenkemåte, og til at de får muligheten til å reflektere over hvordan naturvitenskapelig kunnskap utvikles» (Utdanningsdirektoratet, ... -

Klassestørrelsens betydning for undervisningens innhold. En sammenligning av læreres undervisningspraksis i liten og stor klasse
(Master thesis, 2018-05-08)The importance of class size for the content of the teaching is a master's thesis that, using qualitative methods, tries to answer the question of how is the content of mathematics teaching in the upper secondary school ... -
Kleptoparasitic relationships between common eiders (Somateria mollissima) and large gulls in Solheimsviken, Bergen
(Master thesis, 2021-11-22)Kleptoparasitism is defined as the theft of procured resources from another individual and is common in many species, especially so in birds. This kind of interaction is well documented between common eiders and gulls. ... -
