Experiments and Models of Carbon Black-based Nanofluids for Photothermal and Electrical Applications
(Doctoral thesis, 2023-06-26)Nanofluid er en type væske som inneholder spredte nanopartikler, som kan forbedre deres termiske og elektriske egenskaper sammenlignet med basevæsker. Dette har ført til omfattende bruksområder, som for eksempel solenergilagring. ... -
An explicit IMF By dependence on solar wind ‐ magnetosphere coupling
(Peer reviewed; Journal article, 2019)Presently, all empirical coupling functions quantifying the solar wind—magnetosphere energy—or magnetic flux conversion assume that the coupling is independent of the sign of the dawn-dusk component (B𝑦) of the Interplanetary ... -
Explicit tracking of CO2-flow at the core scale using micro-Positron Emission Tomography (μPET)
(Journal article; Peer reviewed, 2020)Safe subsurface sequestration of carbon dioxide (CO2) is becoming increasingly important to meet climate goals and curb atmospheric CO2 concentrations. The world-wide CO2 storage capacity in carbonate formations is ... -
Explicit volume-preserving splitting methods for divergence-free ODEs by tensor-product basis decompositions
(Peer reviewed; Journal article, 2014-02-23)We discuss the construction of volume-preserving splitting methods based on a tensor product of single-variable basis functions. The vector field is decomposed as the sum of elementary divergence-free vector fields (EDFVFs), ... -
Exploiting graph structures for computational efficiency
(Doctoral thesis, 2020-05-07)Coping with NP-hard graph problems by doing better than simply brute force is a field of significant practical importance, and which have also sparked wide theoretical interest. One route to cope with such hard graph ... -
Exploration of jet substructure using iterative declustering in pp and Pb–Pb collisions at LHC energies
(Journal article; Peer reviewed, 2020)The ALICE collaboration at the CERN LHC reports novel measurements of jet substructure in pp collisions at √s = 7 TeV and central Pb–Pb collisions at √sNN = 2.76 TeV. Jet substructure of track-based jets is explored via ... -

Exploration of non-spinning ^1H NMR Spectroscopy as a Tool for Determination and Monitoring of Gas Hydrate Formation and Dissociation Processes
(Master thesis, 2015-11-02)Natural gas hydrates provide both a flow- assurance hazard and a potential fossil fuel source. In order to face the challenges presented by these scenarios, a greater understanding of the properties of hydrates in a range ... -
An Exploratory Analysis of Multi-Class Uncertainty Approximation in Bayesian Convolutional Neural Networks
(Master thesis, 2018-11-22)Neural networks are an important and powerful family of models, but they have lacked practical ways of estimating predictive uncertainty. Recently, researchers from the Bayesian machine learning community developed a ... -
Exploratory multivariate analysis of the effect of fatty fish consumption and medicinal use on heart rate and heart rate variability data
(Peer reviewed; Journal article, 2015-02-17)The overall aim of the present study was to explore the relationship between medicinal use and fatty fish consumption on heart rate variability (HRV) and heart rate (HR) in a group of forensic inpatients on a variety of ... -
Exploring Arctic-midlatitude teleconnections using observations and numerical models
(Doctoral thesis, 2021-05-27)The Arctic is warming at a much faster rate than the rest of the globe, with large declines in sea ice, snow cover and permafrost over the last decades. These profound changes have been proposed to influence the midlatitude ... -
