Habitatkrav og diversitet hos vedlevende biller på dødved av lind (Tilia cordata) i Norge
(Master thesis, 2015-07-01)Dødved er et viktig habitat for artsmangfoldet i skog. Dette artsmangfoldet gjør en viktig økosystemtjeneste som nedbrytere og resirkulerer næringsstoffer i skogøkosystemet. Biller (Coleoptera) utgjør en stor andel av dette ... -
Hadronic resonances, strange and multi-strange particle production in Xe-Xe and Pb-Pb collisions with ALICE at the LHC
(Peer reviewed; Journal article, 2019)We present measurements of hadronic resonance, strange and multi-strange particle production in collisions of Xe-Xe and Pb-Pb at the center-of-mass energies of √sNN = 5.44 and 5.02 TeV, respectively, by the ALICE collaboration ... -
Half a century of genetic interaction between farmed and wild Atlantic salmon: Status of knowledge and unanswered questions
(Peer reviewed; Journal article, 2017)Atlantic salmon (Salmo salar) is one of the best researched fishes, and its aquaculture plays a global role in the blue revolution. However, since the 1970s, tens of millions of farmed salmon have escaped into the wild. ... -
The Hall current system revealed as a statistical significant pattern during fast flows
(Peer reviewed; Journal article, 2008-11-05)We have examined the dawn-dusk component of the magnetic field, BY , in the night side current sheet during fast flows in the neutral sheet. 237 h of Cluster data from the plasma sheet between 2 August 2002 and 2 October ... -
Halokinetic modulation of sedimentary thickness and architecture: A numerical modelling approach
(Journal article; Peer reviewed, 2021)Subsurface salt flow can deform overlying strata and influence contemporaneous sedimentary systems. Studying salt-sediment interactions is challenging in the subsurface due to poor imaging adjacent to salt, and in the field ... -
The handbook for standardized field and laboratory measurements in terrestrial climate change experiments and observational studies (ClimEx)
(Peer reviewed; Journal article, 2019-11-05)1. Climate change is a world‐wide threat to biodiversity and ecosystem structure, functioning and services. To understand the underlying drivers and mechanisms, and to predict the consequences for nature and people, we ... -
Happy hatchday! How does timing of hatching affect the survival of larval Gadus morhua in a changing environment?
(Master thesis, 2019-06-22)The classical match-mismatch hypothesis proposes that the timing between larval first feeding and food availability is an important driver of year-class strength. With climate change and the warming of the oceans, it is ... -
Hard Mathematical Problems in Cryptography and Coding Theory
(Doctoral thesis, 2020-04-28)In this thesis, we are concerned with certain interesting computationally hard problems and the complexities of their associated algorithms. All of these problems share a common feature in that they all arise from, or have ... -
Hardness of Non-trivial Generalized Domination Problems Parameterized by Linear Mim-Width

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 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 ... -

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 ...
