• The interaction between transpolar arcs and cusp spots ﻿

(Peer reviewed; Journal article, 2015-11-25)
Transpolar arcs and cusp spots are both auroral phenomena which occur when the interplanetary magnetic field is northward. Transpolar arcs are associated with magnetic reconnection in the magnetotail, which closes magnetic ...
• Interaction of piezoelectric transducer excited ultrasonic pulsed beams with a fluid-embedded viscoelastic plate. Finite element modeling, angular spectrum modeling and measurements ﻿

(Doctoral thesis, 2014-03-28)
• Interaction of the hydrogen atom with laser fields: a study of relativistic effects in ionization processes ﻿

(Master thesis, 2018-06-14)
• Interactions between CO2, saline water and minerals during geological storage of CO2 ﻿

(Doctoral thesis, 2006-06-30)

(Peer reviewed; Journal article, 2011-01-07)
We demonstrate a feature of the Rydberg blockade mechanism which occurs between two initially excited circular Rydberg atoms. When both atoms are exposed to weak time-dependent electric fields, it is shown that the intrashell ...
• Intercomparison of the POES/MEPED Loss Cone Electron Fluxes With the CMIP6 Parametrization ﻿

(Peer reviewed; Journal article, 2019)
Quantitative measurements of medium energy electron (MEE) precipitation (>40 keV) are a key to understand the total effect of particle precipitation on the atmosphere. The Medium Energy Proton and Electron Detector (MEPED) ...
• Interface Design for the Gigabit Transceiver Common Readout Unit ﻿

(Master thesis, 2016-06-01)
The future upgrade of the Large Hadron Collider accelerator, the High-Luminosity LHC, has its goal of increasing the beam luminosity by ten times. This will lead to a corresponding growth of the amount of data to be treated ...
• Interplanetary Magnetic Field Bx Component Influence on Horizontal and Field-Aligned Currents in the Ionosphere ﻿

(Peer reviewed; Journal article, 2018-05)
Statistical analyses have shown that the sunward component of the interplanetary magnetic field, Bx (Geocentric Solar Magnetospheric), moderately but significantly affects the auroral intensity. These observations have ...
• Interplanetary Magnetic Field Control of Polar Ionospheric Equivalent Current System Modes ﻿

(Peer reviewed; Journal article, 2019)
We analyze the response of different ionospheric equivalent current modes to variations in the interplanetary magnetic field (IMF) components By and Bz. Each mode comprises a fixed spatial pattern whose amplitude varies ...
• Interpretation of geometrical effects in consequence modelling. Comparison study between the commercial consequence assessment tools FLACS and PHAST for flammable gas dispersion ﻿

(Master thesis, 2014-04-02)
Computational fluid dynamics and integral consequence modeling is today a crucial part of safety assessments worldwide. The models are widely used to predict the effects of ventilation patterns, hazardous gas dispersion, ...
• Invariant Mass Distributions of SUSY Cascade Decays ﻿

(Master thesis, 2011-06-01)
If supersymmetry (SUSY) is realised at experimental energies and R-parity is conserved, sparticles might be produced and decay in cascades at the LHC. A neutral LSP will escape detection, complicating the reconstruction ...
• Investigating correlated fluctuations of conserved charges with net-Λ fluctuations in Pb–Pb collisions at ALICE ﻿

(Peer reviewed; Journal article, 2019)
Event-by-event fluctuations of conserved charges – such as electric charge, strangeness, and baryon number – in ultrarelativistic heavy-ion collisions provide insight into the properties of the quark-gluon plasma and the ...
• Investigating the energy yield of rain cells ﻿

(Master thesis, 2018-12-08)
Harvesting energy from rain has been done indirectly for hundreds of years by building dams or reservoirs. Recently, research has been made into gathering energy from individual raindrops. One of the discovered methods ...
• Investigating the Role of Coherence Effects on Jet Quenching in Pb-Pb Collisions at $\sqrt{s_{NN}} =2.76$ TeV using Jet Substructure ﻿

(Peer reviewed; Journal article, 2017-11)
We report measurements of two jet shapes, the ratio of 2-Subjettiness to 1-Subjettiness $\it{\tau_{2}}/\it{\tau_{1}}$ and the opening angle between the two axes of the 2-Subjettiness jet shape, which is obtained by ...
• Investigation into the impact of solid surfaces in aqueous systems ﻿

(Doctoral thesis, 2016-03-03)
Global warming is upon us. The scientiﬁc community is searching for methods of slowing down, preventing and reversing its effects. Carbon dioxide have been at the center of attention the last few decades, being the main ...
• Investigation of instability and turbulence effects on gas explosions: experiments and modelling ﻿

(Doctoral thesis; Peer reviewed, 2018-03-09)
Safe design of industrial facilities requires models that can predict the consequences of accidental gas explosions in complex geometries with sufficient accuracy. Computa- tional fluid dynamics (CFD) models are widely ...
• Investigation of Low Salinity Polymer and Surfactant Flooding in Carbonate Reservoir at Reservoir Conditions ﻿

(Master thesis, 2018-04-20)
It is estimated that 40-60% of the world’s total hydrocarbon production is from carbonate rocks [1]. Carbonate rocks contain the world`s largest fields in the Middle East (i.e., Ghawar Field, Saudi Arabia). Waterflooding ...
• Investigation of Particle Trajectories and Flow Patterns in a Hydrocyclone by Positron Emission Particle Tracking (PEPT) ﻿

(Master thesis, 2012-05-31)
Cyclone separators are widely used for separation of solids or droplets from gaseous or liquid fluids in several industries. Cyclones can be used for many purposes and each cyclone can be fitted to its area of use. In the ...
