Comparison of Iterative Solvers for Non-Symmetric Linear Systems in Porous Media Problems
(Master thesis, 2014-09-02)We investigate the performance of the IDR(s)-algorithms when solving nonsymmetric systems in porous media problems. We derive a mathematical model for the flow in porous media, and discretized this with the method known ... -
A comparison of Langmuir turbulence parameterizations and key wave effects in a numerical model of the North Atlantic and Arctic Oceans
(Peer reviewed; Journal article, 2019)Five different parameterizations of Langmuir turbulence (LT) effect are investigated in a realistic model of the North Atlantic and Arctic using realistic wave forcing from a global wave hindcast. The parameterizations ... -
A Comparison of LiDAR and Radiosonde Wind Measurements
(Peer reviewed; Journal article, 2014)Doppler LiDAR measurements are already well established in the wind energy research and their accuracy has been tested against met mast data up to 100 m above ground. However, the new generation of scanning LiDAR have a ... -
Comparison of metamorphic evolution and tectonic position of metasediments of the Austevoll islands with rocks from the Samnanger Complex (Major Bergen Arc, Norwegian Caledonides)
(Master thesis, 2015-08-01)Metasedimentary rocks represent a substantial component of the Bergen Arcs System and they are mostly confined to the Minor and Major Bergen Arcs. The arcs represents imbricate structures composed of island arc lithologies, ... -
Comparison of methods for finding the capacitance of a supercapacitor
(Journal article; Peer reviewed, 2021)A carbon-based supercapacitor is usually associated with a capacitance such that the user can access its ability to store electrical charge. Three different measurement methods or variations thereof are typically employed ... -
A comparison of Monte Carlo sampling methods for metabolic network models
(Journal article; Peer reviewed, 2020)Reaction rates (fluxes) in a metabolic network can be analyzed using constraint-based modeling which imposes a steady state assumption on the system. In a deterministic formulation of the problem the steady state assumption ... -
Comparison of OpenMP and Threading Building Blocks for expressing parallelism on shared-memory systems
(Master thesis, 2011-02-01)The thesis offers a comparison of OpenMP and Intel Threading Building blocks. The two are threading packages used to express parallelism in programs. In addition, the thesis presents a promising scalable algorithm for ... -
Comparison of Otolith Microstructure of Herring Larvae and Sibling Adults Reared Under Identical Early Life Conditions
(Journal article; Peer reviewed, 2020-07-03)Atlantic herring (Clupea harengus) is a euryhaline species, occupying fully marine habitats (35 psu) in the North Atlantic, as well as brackish waters (<20 psu) such as in the adjacent Baltic Sea. We co-reared Atlantic ... -
Comparison of planar and 3D silicon pixel sensors used for detection of low energy antiprotons
(Peer reviewed; Journal article, 2014-12)The principle aim of the AEḡIS experiment at CERN is to measure the acceleration of antihydrogen due to Earth’s gravitational field. This would be a test of the Weak Equivalence Principle, which states that all bodies fall ... -
Comparison of Quality Measures for Walén Relation
(Journal article; Peer reviewed, 2020)The standard method for identifying magnetohydrodynamic rotational discontinuities in spacecraft data has been to examine how well the Walén relation is satisfied. In this paper, we apply two different versions of the Walén ... -
Comparison of residual oil cluster size distribution, morphology and saturation in oil-wet and water-wet sandstone
(Peer reviewed; Journal article, 2012-06-01)We imaged an oil-wet sandstone at residual oil saturation (Sor) conditions using X-ray micro-tomography with a nominal voxel size of (9 μm)3 and monochromatic light from a synchrotron source. The sandstone was rendered ... -
Comparison of RNA-folding structures, in-vivo, in-vitro and in-silico
(Master thesis, 2019-10-31)The main objective of the work has been to develop the understanding of the difference between RNA structure probing approaches; in vivo, in vitro and in silico. Similarities and differences between three libraries of data ... -
Comparison of Solving Techniques for Non-linear Sparse Equations over Finite Fields with Application in Cryptanalysis
(Master thesis, 2008)The work on this thesis gives a summary of the Gluing/Agreeing techniques, as well as a reference implementation of this methods. Furthermore widely used SAT-solving techniques are explained and a short insight to the ... -
Comparison of the efficiency (flash point, freezing point, and viscosity test) of biodiesels from Sargassum sp.
(Peer reviewed; Journal article, 2019)Biodiesel, an alkyl ester compound produced through an alcoholysis process (transesterification) between triglycerides and methanol or ethanol with the help of alkaline catalysts into alkyl esters and glycerol, is an ... -
A Comparison of Two Numerical Models for Flow in Fractured Porous Media and the Impact of Fracture Intersection Cell Removal
(Master thesis, 2016-11-21)The simulation of flow and transport in fractured porous media is crucial to improve understanding and viability of geothermal energy. It is also challenging, due to complex geometries and large scale differences. In this ... -
A Comparison of Vertex and Edge Partitioning Approaches for Parallel Maximal Matching
