Optimisation of large-radius jet reconstruction for the ATLAS detector in 13 TeV proton–proton collisions
(Journal article; Peer reviewed, 2021)Jet substructure has provided new opportunities for searches and measurements at the LHC, and has seen continuous development since the optimization of the large-radius jet definition used by ATLAS was performed during Run ... -
Optimization of proton therapy plans with respect to biological and physical dose distributions
(Master thesis, 2018-06-16)Introduction: Proton therapy is a radiation treatment method growing around the world. This is mainly due to the protons ability to deposit dose more conformal compared to conventional photon therapy. Protons also differ ... -
Optimization, evaluation and application of EEP measurements in the presence of contaminating protons
(Master thesis, 2017)It is well known that energetic particles can penetrate deep into the atmosphere and initiate a chain of chemical reactions, ultimately leading to enhanced production rates of HOx and NOx molecules and the depletion of ... -
Optimized mesoscale growth of microalgae: A modelling approach
(Master thesis, 2017-11-20)Photosynthesis is a process that uses water, carbon dioxide and light to create sugar and oxygen. Sugar and oxygen is then used by the cell for maintenance and growth purposes through cellular respiration. We would then ... -
Optimizing hydroxyl airglow retrievals from long-slit astronomical spectroscopic observations
(Peer reviewed; Journal article, 2017-08-25)Astronomical spectroscopic observations from ground-based telescopes contain background emission lines from the terrestrial atmosphere's airglow. In the near infrared, this background is composed mainly of emission from ... -
Optisk goniometer for optimalisering av retningsbestemt solenergi
(Master thesis, 2017-06-13)Det er et økende fokus på fornybar energi og bærekraftig matproduksjon, det vil derfor være nyttig med teknologi som kan føre til økt effektivitet i produksjon av dette. Utnyttelse av solenergi er et felt som er mye brukt, ... -
An organ deformation model using Bayesian inference to combine population and patient-specific data
(Journal article; Peer reviewed, 2023)Objective. Organ deformation models have the potential to improve delivery and reduce toxicity of radiotherapy, but existing data-driven motion models are based on either patient-specific or population data. We propose to ... -
The Organ Sparing Potential of Different Biological Optimization Strategies in Proton Therapy
(Journal article; Peer reviewed, 2021)Purpose: Variable relative biological effectiveness (RBE) models allow for differences in linear energy transfer (LET), physical dose, and tissue type to be accounted for when quantifying and optimizing the biological ... -
Origin and development of the Godbert-Greenwald furnace for measuring minimum ignition temperatures of dust clouds
(Journal article; Peer reviewed, 2019)Hot surfaces that can ignite explosible dust clouds can occur in various process situations in industry, e.g. inside furnaces, burners and dryers of various kinds. Hot surfaces can also be generated accidentally e.g. by ... -
Outlook of solar energy in Europe based on economic growth characteristics
(Peer reviewed; Journal article, 2019)Solar power production in Europe has raised from about 130 MW to 110 GW of installed capacity (corresponding to 90 GWh to 120 TWh in annual electricity generation) during the present century. Together with wind power, it ... -
Overview of solar wind - magnetosphere - ionosphere - atmosphere coupling and the generation of magnetospheric currents
(Peer reviewed; Journal article, 2017-03)We review the morphology and dynamics of the electrical current systems of the terrestrial magnetosphere and ionosphere. Observations from the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) ... -
Overview of the Rocket Experiment for NeutralUpwelling Sounding Rocket 2 (RENU2)
(Journal article; Peer reviewed, 2020)The Rocket Experiment for Neutral Upwelling 2 (RENU2) rocket was launched on 13 December 2015 at 07:34 UT. The payload transited the cusp region during a neutral upwelling event, supported by a comprehensive set of onboard ... -
Parameter Scans and Machine Learning for beyond Standard Model Physics
(Doctoral thesis, 2019-05-02)This thesis focuses on different beyond Standard Model theories, and the use of statistical methods to investigate them. Supersymmetry is considered in different contexts. First, the supersymmetry breaking scheme of gaugino ... -
