Hardness of Non-trivial Generalized Domination Problems Parameterized by Linear Mim-Width
(Master thesis, 2022-06-01) -
Hardware and Software Studies for the Alignment of the Proton CT
(Master thesis, 2023-06-15)Proton therapy is a form of particle therapy using protons to irradiate tumors as a form of cancer treatment. It is becoming more and more popular around the world, including in Norway. To locate the tumor, conventional ... -
Hardware architecture of Dillon's APN permutation for different primitive polynomials
(Journal article; Peer reviewed, 2023)Cryptographically strong functions used as S-boxes in block cyphers are fundamental for the cypher’s security. Their representation as lookup tables is possible for functions of small dimension. For larger dimensions, this ... -
Harnessing the potential of CT scanning to identify cryptotephra in sediment cores: a controlled experiment.
(Master thesis, 2019-12-20)Volcanic ash (tephra) is a powerful geochronological tool, called tephrochronology, as rapid widespread deposition in multiple environments allows for correlation of geological archives across vast areas. It can thus help ... -
Harvesting electrical energy from air bubbles sliding along a fluoropolymer
(Master thesis, 2023-09-01) -
Harvesting electrical energy from water drops falling on a vibrating cantilever
(Journal article; Peer reviewed, 2022)In this work a novel thin-film device combining piezoelectric and contact electrification energy harvesting is created with the aim of investigating how it responds to water droplet impact during vibrations. The two energy ... -
Harvesting energy from light and water droplets by covering photovoltaic cells with transparent polymers
(Journal article; Peer reviewed, 2021)Energy harvesting of sunlight is often done using photovoltaic cells covered by a protective layer of polymer or glass. Currently, this layer does not have any other function than being transparent and protective, but its ... -
Harvesting forage fish can prevent fishing-induced population collapses of large piscivorous fish
(Journal article; Peer reviewed, 2021)Fisheries have reduced the abundances of large piscivores—such as gadids (cod, pollock, etc.) and tunas—in ecosystems around the world. Fisheries also target smaller species—such as herring, capelin, and sprat—that are ... -
Has a warm North Atlantic contributed to recent European cold winters?
(Peer reviewed; Journal article, 2014-06-02)The rise of global surface temperature waned during the last decade, despite increasing greenhouse gas concentrations. The temperature changes were most pronounced over northern hemisphere land masses during winter (Cohen ... -
Hash functions in Cryptography
(Master thesis, 2008)This thesis is concerned with giving both an overview of the application of hash functions in cryptography and a presentation of today's standard cryptographic hash functions. Cryptographic hash functions are a valuable ... -
Hashfunksjoner for bruk i Digitale Signaturer

Hatching time and alevin growth prior to the onset of exogenous feeding in farmed, wild and hybrid Norwegian Atlantic salmon
(Peer reviewed; Journal article, 2014-12-01)The onset of exogenous feeding, when juveniles emerge from the gravel, is a critical event for salmonids where early emergence and large size provide a competitive advantage in the wild. Studying 131 farmed, hybrid and ... -
Heads and tails: The notochord develops differently in the cranium and caudal fin of Atlantic Salmon (Salmo salar, L.)
(Journal article; Peer reviewed, 2020)While it is well known that the notochord of bony fishes changes over developmental time, less is known about how it varies across different body regions. In the development of the Atlantic salmon, Salmo salar L., cranial ... -
Heat flux variations in the eastern Norwegian Atlantic Current toward
(Geophysical Research Letters;32(2005) L14, Journal article, 2005-07-21) -
Heat Transfer Upscaling in Geothermal Reservoirs
(Master thesis, 2015-11-20)In this thesis we implement a numerical model of heat transfer in geothermal reservoirs. We use existing pressure and flow transport solvers as a starting point to investigate discretization techniques for a convection-conduction ... -
Heavy and light chain homologs of ferritin are essential for blood-feeding and egg production of the ectoparasitic copepod Lepeophtheirus salmonis
(Peer reviewed; Journal article, 2019)The salmon louse, Lepeophtheirus salmonis, is a hematophagous ectoparasite of salmonid fish. Due to its blood-feeding activity, the louse is exposed to great amounts of iron, which is an essential, yet potentially toxic ... -
Heavy flavor azimuthal correlations in PYTHIA generated proton-proton collisions at LHC energies
(Master thesis, 2014-11-20)The ALICE detector at CERN is a promising tool for the study of the Quark-Gluon Plasma (QGP), an exotic state of matter thought to be present in the early Universe. The study of partonic energy loss reveals vital information ... -
Heavy Higgs boson decays in the alignment limit of the 2HDM
(Peer reviewed; Journal article, 2018-12)The Standard Model (SM)-like couplings of the observed Higgs boson impose strong constraints on the structure of any extended Higgs sector. We consider the theoretical properties and the phenomenological implications of a ... -
Heavy Metal and Rock in Space: Cluster RAPID Observations of Fe and Si
(Journal article; Peer reviewed, 2021)Metallic and silicate ions carry essential information about the evolution of the Earth and near-Earth small bodies. Despite this, there has so far been very little focus on ions with atomic masses higher than oxygen in ... -
Heavy-flavour hadron decay leptons in Pb–Pb and Xe–Xe collisions at the LHC with ALICE
(Peer reviewed; Journal article, 2019)Heavy quarks, i.e. charm and beauty, are sensitive probes of the medium produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, mainly in hard partonic scattering processes, and ...
