Fine-Tuning of Faster Region-Based Convolutional Neural Network for Automatic Core Plug Detection in Optical Core Images
(Master thesis, 2020)Denne oppgaven presenterer to fremgangsmåter for å trene en Faster Region-based Convolutional Neural Network (Faster R-CNN) objektgjenkjenningsmodell. Denne modellen kan brukes til automatisk gjenkjenning av både CCA og ... -
Finite-difference modelling of wavefield constituents
(Journal article; Peer reviewed, 2015)The finite-difference method is among the most popular methods for modelling seismic wave propagation. Although the method has enjoyed huge success for its ability to produce full wavefield seismograms in complex models, ... -
First hyperspectral imaging survey of the deep seafloor: High-resolution mapping of manganese nodules
(Journal article; Peer reviewed, 2018)Hyperspectral seafloor surveys using airborne or spaceborne sensors are generally limited to shallow coastal areas, due to the requirement for target illumination by sunlight. Deeper marine environments devoid of sunlight ... -
A First-Order Statistical Exploration of the Mathematical Limits of Micromagnetic Tomography
(Peer reviewed; Journal article, 2022)The recently developed Micromagnetic Tomography (MMT) technique combines advances in high resolution scanning magnetometry and micro X-ray computed tomography. This allows precise recovery of magnetic moments of individual ... -
Flipped classroom in engineering education: the views of the main stakeholders
(Journal article, 2020)Flipped classroom is a blended learning approach that is increasingly gaining popularity in university education in the recent years. This paper discusses the use of the flipped classroom approach in the context of a ... -
Flomskred: Utløsningsårsaker karakteristiske geomorfologiske trekk og utløpsdistanser
(Master thesis, 2011)Flomskred går under kategorien vannrelaterte skred, og er en hurtig, flytende massebevegelse. Grunnet høyt vanninnhold har flomskred høy mobilitet, og avhengig av størrelse kan de ha store ødeleggende krefter. En flomskredbane ... -
A flotation-based approach to the quantification of pyrrhotite in concrete aggregates
(Journal article; Peer reviewed, 2021)Pyrrhotite-bearing aggregates are a major cause of internal sulphate attack (ISA) in concrete. The concentration of pyrrhotite is usually too low to permit direct accurate quantification. Hence, safety restrictions put on ... -
Flow of non-Newtonian fluids in single fractures and fracture networks: Current status, challenges, and knowledge gaps
(Peer reviewed; Journal article, 2023)Flow of non-Newtonian fluids in rock fractures is ubiquitous in engineering practice and involves e.g. cement flow in tunnel grouting, drilling fluid flow when a fracture is met during drilling, and flow of fracturing ... -
Flow properties of water-based drilling fluids
(Master thesis, 2013)The objective of this master thesis was to investigate the flow properties of water based drilling fluids, utilizing measurements in both the micro and macro scale. The research was performed on two realistic drilling ... -
Flow Transformation in Lower and Upper Turbidite Units, NE Helgeland Basin, Offshore Mid-Norway
(Master thesis, 2018)Sediment transport towards the ocean floor is mainly by sediment gravity flows, either dominated by one flow process such as a slide, slump, debris flow or turbidity current, or more complex flows combining e.g. debris ... -
