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 ...

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 ...

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 ﻿

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 ...
• #### Investigation of the possibilities for seabottom characterization using echosounder data ﻿

(Master thesis, 2009-11-18)
This thesis focuses mainly on using the information present in the first echo returned from the seafloor, using a normal-incidence echosounder, to characterize or classify the seabed. This is done using a monostatic setup ...
