GPS scintillations associated with cusp dynamics and polar cap patches
(Peer reviewed; Journal article, 2017)This paper investigates the relative scintillation level associated with cusp dynamics (including precipitation, flow shears, etc.) with and without the formation of polar cap patches around the cusp inflow region by the ... -
Graphene and graphene oxide on Ir(111) are transparent to wetting but not to icing
(Journal article; Peer reviewed, 2021)Anti-icing coatings reduce the freezing onset temperature for water by changing the chemical and physical environment at the water-substrate interface to prevent ice nucleation and growth. Graphene oxide has several ... -
Gravitino dark matter and the flavour structure of R-violating operators
(Peer reviewed; Journal article, 2009-06-15)We study gravitino dark matter and slow gravitino decays within the framework of R-violating supersymmetry, with particular emphasis on the flavour dependence of the branching ratios and the allowed R-violating couplings. ... -
Gravitino Dark Matter with Entropy Production constrained by Big Bang Nucleosynthesis
(Master thesis, 2016-12-16)We are looking at a gravitino dark matter scenario with a general neutralino next-to-lightest supersymmetric particle. We are considering the primary decay channels of the neutralino, and we define the supersymmetric ... -
Grid sensitivity simulation of low salinity and polymer flooding
(Master thesis, 2015-05-31)Water flooding in a reservoir is a well- established recovery method used to maintain the reservoir pressure and to displace the oil towards the producing well. However, after water flooding there is still a substantial ... -
Ground-based and Satellite Remote Sensing of Atmospheric Aerosols and Ultraviolet Solar Radiation
(Doctoral thesis, 2016-04-08)Satellite remote sensed data have been used to determine the aerosol climatology and to investigate the influence of the aerosol index (AI) on the ultraviolet (UV) index in coastal land areas in Serrekunda (13.28◦ N, 16.34◦ ... -
Ground-based measurements of total ozone column amount with a multichannel moderate-bandwidth filter instrument at the Troll research station, Antarctica
(Journal article; Peer reviewed, 2020)Combining information from several channels of the Norwegian Institute for Air Research (NILU-UV) irradiance meter, one may determine the total ozone column (TOC) amount. A NILU-UV instrument has been deployed and operated ... -
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 ... -
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 ... -

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 ... -
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 ... -
Height Determination of a Blue Discharge Observed by ASIM/MMIA on the International Space Station
(Journal article; Peer reviewed, 2023)We analyze simultaneous photometric observations of thundercloud discharges from the Modular Multispectral Imaging Array of the Atmosphere-Space Interactions Monitor (ASIM) on board the International Space Station with ... -
Helium radiography with a digital tracking calorimeter—a Monte Carlo study for secondary track rejection
(Journal article; Peer reviewed, 2021)Radiation therapy using protons and heavier ions is a fast-growing therapeutic option for cancer patients. A clinical system for particle imaging in particle therapy would enable online patient position verification, ... -
