A Fast Continuous Max-Flow Approach to Non-Convex Multilabeling Problems
(Journal article, 2011)This work addresses a class of multilabeling problems over a spatially continuous image domain, where the data fidelity term can be any bounded function, not necessarily convex. Two total variation based regularization ... -
Fast evolving 18S rRNA sequences from Solenogastres (Mollusca) resist standard PCR amplification and give new insights into mollusk substitution rate heterogeneity
(Peer reviewed; Journal article, 2010-03-09)Background: The 18S rRNA gene is one of the most important molecular markers, used in diverse applications such as molecular phylogenetic analyses and biodiversity screening. The Mollusca is the second largest phylum within ... -
Fast Image Segmentation Using Variational Optimization Methods With Edge Detector
(Master thesis, 2014-06-02)In this work, we apply techniques in variational optimization to image segmentation. We study three different segmentation models: one is based on the active contour method, the second is based on a piecewise constant level ... -
A fast Level Set Method for Reservoir Simulation
(Department of Applied Mathematics report, Research report, 1999-05) -
Fast Liquid Chromatography Coupled with Tandem Mass Spectrometry for the Analysis of Vanillic and Syringic Acids in Ice Cores
(Journal article; Peer reviewed, 2022)The development of new analytical systems and the improvement of the existing ones to obtain high-resolution measurements of chemical markers in samples from ice cores, is one of the main challenges the paleoclimatic ... -
Fast Method for Maximum-Flow Problem with Minimum-Lot Sizes
(Master thesis, 2015-03-03)In transportation networks, such as pipeline networks for transporting natural gas, it is often impractical to send across amounts of flow below a certain threshold. Such lower threshold is referred as the minimum-lot size. ... -
Fast methods to solve the pooling problem
(Master thesis, 2014-05-31)In pipeline transportation of natural gas, simple network flow problems are replaced by hard ones when bounds on the flow quality are imposed. The sources, typically represented by gas wells, provide flow of unequal ... -
Fast Mie calculations with a radial basis function neural network
(Master thesis, 2019-02-22)Scattering phenomena have been of great interest and driving scientific advancement for centuries. Mie theory outlines a precise way to compute the scattering by spherical particles. However, the computational labor involved ... -
Fast photodegradation of antibiotics and dyes by anionic surfactant-aided CdS/ZnO nanodispersion
(Journal article; Peer reviewed, 2022)The photocatalytic technology has broad applications in energy and environmental science. In this study, we synthesized a type II heterojunction CdS/ZnO (CSZ) nanodispersion by means of one-pot precipitation. Different ... -
Fast resolution change in neutral helium atom microscopy
(Peer reviewed; Journal article, 2018)In neutral helium atom microscopy, a beam of atoms is scanned across a surface. Though still in its infancy, neutral helium microscopy has seen a rapid development over the last few years. The inertness and low energy of ... -
Fast robust optimization using bias correction applied to the mean model
(Peer reviewed; Journal article, 2021)Ensemble methods are remarkably powerful for quantifying geological uncertainty. However, the use of the ensemble of reservoir models for robust optimization (RO) can be computationally demanding. The straightforward ... -
Fast water currents reduce production performance of post-smolt Atlantic salmon Salmo salar
(Peer reviewed; Journal article, 2015-09-17)In the future, an increasing number of salmon farms may be located in areas with fast water current velocity due to limited availability of more sheltered locations. However, there is little information as to how fast ... -
Fast-fase NMR-spektroskopi og MRI-studier av fettsyreprofiler direkte på fiskekjøtt. En sammenligning av oppdrettslaks og villaks
(Master thesis, 2018-06-28)The purpose of this project has been to determine the fat content, fat distribution and fatty acid composition in wild and farmed salmon using solid-state Nuclear Magnetic Resonance (NMR) spectroscopy and Magnetic Resonance ... -
Faster enumeration of minimal connected dominating sets in split graphs
(Master thesis, 2017-06-20)Graphs are mathematical objects that can be used to model many real world problems. An example is a roadmap, where the nodes in the graph represent cities and the edges of the graph represent roads. An interesting and ... -

The fate of the Atlantic Water in the North Icelandic Irminger Current
(Master thesis, 2012-01-19)The fate of the Atlantic Water within the North Icelandic Irminger Current has long been questioned. The North Icelandic Irminger Current flows along the Icelandic shelf area to the west and north of Iceland, bringing warm ... -
Fate of Warm Pacific Water in the Arctic Basin
(Journal article; Peer reviewed, 2021)Pacific Summer Water (PSW) plays a critical role in the ecosystem of the western Arctic Ocean, impacting sea-ice melt and providing freshwater to the basin. Most of the water exits the Chukchi Sea shelf through Barrow ... -
Fault core and its geostatistical analysis: Insight into the fault core thickness and fault displacement
(Master thesis, 2017-06-23)Fault core is a high-strain zone of a fault, which accommodate intense deformation. Due to high strain, complex structures and intensely deformed fault rocks form in the fault core, which again affects the geometry and ... -
