(Doctoral thesis, 2023-09-15)I de senere år har det vært en økning i observasjonsbaserte, re-analytiske og modellbaserte studier som viser korrelasjoner mellom dag-til-dag og år-til-år solaktivitet og klima-/vær-mønstre. Det overordnede målet med ... -
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 ... -
An investigation into the spectral parameters of ultra-low-frequency (ULF) waves in the polar caps and magnetotail
(Journal article; Peer reviewed, 2022)The present case study is focused on fluctuations at ∼ 1.5 mHz observed on open field lines in both of the polar caps in ground-based geomagnetic data and in the electron concentration in the Northern Hemisphere ionosphere. ... -
Investigation of instability and turbulence effects on gas explosions: experiments and modelling
(Doctoral thesis, 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 nanofluids in alkaline electrolytes: Stability, electrical properties, and hydrogen production
(Journal article; Peer reviewed, 2023)Utilizing solar energy efficiently and manufacturing hydrogen economically are the primary goals in the energy industry. In this paper, we present a novel method to solve both issues by exploiting the electrolysis of ... -
