The impact of energetic electron precipitation on mesospheric hydroxyl during a year of solar minimum
(Peer reviewed; Journal article, 2016-06)In 2008 a sequence of geomagnetic storms occurred triggered by high-speed solar wind streams from coronal holes. Improved estimates of precipitating fluxes of energetic electrons are derived from measurements on board the ... -
The Impact of Energetic Electron Precipitation on Mesospheric Hydroxyl Radical
(Doctoral thesis, 2018-12-12) -
The Impact of Oxygen on the Reconnection Rate
(Peer reviewed; Journal article, 2019-05-29)We investigate the role of a background oxygen population in magnetic reconnection, using particle‐in‐cell simulations. We run several simulations, with different initial oxygen temperatures and densities, to understand ... -
Impact of solar irradiance and geomagnetic activity on polar NOx, ozone and temperature in WACCM simulations
(Journal article; Peer reviewed, 2020)The response of the atmosphere to solar irradiance and geomagnetic activity is analyzed in experiments with the Whole Atmosphere Community Climate Model (WACCM) under idealized forcings. Four experiments are carried out ... -
The impact of sunlight on high-latitude equivalent currents
(Peer reviewed; Journal article, 2016-03)Ground magnetic field measurements can be mathematically related to an overhead ionospheric equivalent current. In this study we look in detail at how the global equivalent current, calculated using more than 30 years of ... -
Impact of variable proton relative biological effectiveness on estimates of secondary cancer risk in paediatric cancer patients
(Master thesis, 2018-12-12)Background: Proton therapy has an increased dose-conformity compared to conventional radiotherapy with photons, and paediatric cancer patients receiving cranio-spinal irradiation (CSI) are routinely referred to this treatment ... -
Impacts of Ionospheric Ions on Magnetic Reconnection and Earth's Magnetosphere Dynamics
(Journal article; Peer reviewed, 2021)Ionospheric ions (mainly H+, He+, and O+) escape from the ionosphere and populate the Earth's magnetosphere. Their thermal energies are usually low when they first escape the ionosphere, typically a few electron volt to ... -
Impacts on oil recovery from capillary pressure and capillary heterogeneities
(Doctoral thesis, 2008-06-02)This thesis summarises the findings made in NFR-funded project “Capillary Pressure and Capillary Heterogeneities”. The focus has been to determine the impact on oil recovery from wettability and fractures in carbonate ... -
Implementasjon av interrupt-styrd DMA-overføring på HLT-RORC
(Master thesis, 2005)På CERN i Geneve vert det bygd ein ny partikkelakselerator kalla LHC. Ein av dei fire hovuddetektorane i LHC vert kalla for ALICE. I ALICE-detektoren møtest akselererte blyion i høgenergetiske kollisjonar. Med desse ... -
Implementation of a CAN bus interface for the Detector Control System in the ALICE ITS Upgrade
(Journal article; Peer reviewed, 2020)For the Upgrade of the ALICE Experiment in Long Shutdown 2, a new Inner Tracking System (ITS) is being commissioned, based on the ALPIDE Monolitihic Active Pixel Sensor (MAPS) chip. Data readout from the ALPIDE chips is ... -
Implementation of a double scattering nozzle for Monte Carlo recalculation of proton plans with variable relative biological effectiveness
(Journal article; Peer reviewed, 2020)A constant relative biological effectiveness (RBE) of 1.1 is currently used in clinical proton therapy. However, the RBE varies with factors such as dose level, linear energy transfer (LET) and tissue type. Multiple RBE ... -
Implementation of Improved EDC Combustion Model in the Open LES Code FDS
(Master thesis, 2012-08-09)In this thesis, Magnussen’s and Hjertager’s Eddy Dissipation Concept (EDC) Combustion Model has been implemented in the CFD code Fire Dynamics Simulator (FDS). FDS is an open source non-commercial Large Eddy Simulation ... -
Implications of symmetries in the scalar sector
(Journal article; Peer reviewed, 2020)Symmetries play a very important rôle in Particle Physics. In extended scalar sectors, the existence of symmetries may permit the models to comply with the experimental constraints in a natural way, and at the same time ... -
