Reactive Transport of CO2 in Saline Aquifers with implicit geomechanical analysis
(Peer reviewed; Journal article, 2009)Geological storage of CO2 in saline aquifers is a promising way to reduce the concentration of the greenhouse gas in the atmosphere. Injection of CO2 will, however, lead to dissolution of minerals in regions of lowered pH ... -
Readout Electronics for the Upgraded ITS Detector in the ALICE Experiment
(Doctoral thesis, 2022-06-03)ALICE is undergoing upgrades during the Long Shutdown (LS) 2 of the LHC to improve its performance and capabilities, and to prepare the experiment for the increases in luminosity provided by the LHC in Run 3 and Run 4. One ... -

Recalibration of the MEPED Proton Detectors Onboard NOAA POES Satellites
(Master thesis, 2013-07-04)In this thesis we have calibrated energetic proton data from the solid state detectors of the MEPED instrument onboard the satellites NOAA 15, 16, 17, 18, and MetOp 02. All these satellites are part of the NOAA/POES program, ... -
Reciprocity calibration method for ultrasonic piezoelectric transducers in air
(Master thesis, 2013-06-17)The conventional three-transducer reciprocity calibration method for use in gas at ambient pressure and temperature is studied. Modifications are introduced, introducing correction factors for absorption in air, diffraction ... -
Reciprocity calibration of ultrasonic piezoelectric disks in air
(Master thesis, 2015-11-20)The phase response of a transducer acting as a transmitter or receiver of sound is important in many industrial applications, such as fiscal measurements of natural gas, therein multipath ultrasonic transit-time flow meters, ... -
Reconstruction and identification of boosted di-τ systems in a search for Higgs boson pairs using 13 TeV proton-proton collision data in ATLAS
(Journal article; Peer reviewed, 2020-11-30)In this paper, a new technique for reconstructing and identifying hadronically decaying τ+τ− pairs with a large Lorentz boost, referred to as the di-τ tagger, is developed and used for the first time in the ATLAS experiment ... -
Reconstruction of primary vertices at the ATLAS experiment in Run 1 proton-proton collisions at the LHC
(Peer reviewed; Journal article, 2017-05)This paper presents the method and performance of primary vertex reconstruction in proton--proton collision data recorded by the ATLAS experiment during Run 1 of the LHC. The studies presented focus on data taken during ... -
Recreating the top quark: Commissioning and monitoring of the ATLAS Inner Detector and search for New Physics with heavy particles.
(Doctoral thesis, 2012-02-03)The ATLAS (A Toroidal Lhc ApparatuS) experiment is one of the two general purpose experiments at the Large Hadron Collider (LHC) at CERN, the European Organization for Nuclear Research. The LHC is a proton-proton and ion-ion ... -
Reducing systematic errors due to deformation of organs at risk in radiotherapy
(Journal article; Peer reviewed, 2021)Purpose In radiotherapy (RT), the planning CT (pCT) is commonly used to plan the full RT-course. Due to organ deformation and motion, the organ shapes seen at the pCT will not be identical to their shapes during RT. Any ... -
Reduction of noise in seismic hydrophone arrays modelling of breathing waves and adaptive noise cancelling

Reduction of PTV margins for elective pelvic lymph nodes in online adaptive radiotherapy of prostate cancer patients
(Journal article; Peer reviewed, 2023)Background Cone beam CT (CBCT) based online adaptive radiotherapy (oART) is a new development in radiotherapy. With oART, the requirements for planning target volume (PTV) margins differ from standard therapy because ... -
The refractive and diffractive contributions to GPS signal scintillation at high latitudes during the geomagnetic storm on 7-8 September 2017
(Journal article; Peer reviewed, 2022)Different indices have been used to reflect, or monitor the ionospheric scintillation, e.g. the detrended carrier phase, σφ, S4, the rate of change of the vertical total electron content index (vROTI), as well as the ... -
Reinterpretation of LHC results for new physics: status and recommendations after run 2
(Journal article; Peer reviewed, 2020-08-21)We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental ... -
The Relationship Between Cusp Region Ion Outflows and East-West Magnetic Field Fluctuations at 4,000-km Altitude
(Journal article; Peer reviewed, 2020)A number of interdependent conditions and processes contribute to ionospheric-origin energetic ( ∼ 10 eV to several keV) ion outflows. Due to these interdependences and the associated observational challenges, energetic ... -
The relationship between interhemispheric asymmetries in polar ionospheric convection and the magnetic field line footpoint displacement field
(Journal article; Peer reviewed, 2022)Polar electrodynamics is largely controlled by solar wind and magnetospheric forcing. Different conditions can make plasma convection and magnetic field disturbances asymmetric between hemispheres. So far, these asymmetries ... -
