On the Equivalence of Eulerian and Lagrangian Variables for the Two-Component Camassa–Holm System
(Chapter, 2018)The Camassa–Holm equation and its two-component Camassa–Holm system generalization both experience wave breaking in finite time. To analyze this, and to obtain solutions past wave breaking, it is common to reformulate the ... -
On the Estimation of Extreme Values for Risk Assessment and Management: The ACER Method
(Journal article; Peer reviewed, 2015)In this paper we use an Average Conditional Exceedance Rate (ACER) method to model the tail of the price change distribution of daily spot prices in the Nordic electricity market, Nord Pool Spot. We use an AR-GARCH model ... -
On the Ethics of the Government Pension Fund Global - An Empirical Analysis on the Effects of Public Recommendations on Ethics
(Master thesis, 2018)The Norwegian oil adventure and the unique construction of the Government Pension Fund Global (GPFG), have gradually led to an increase in demand for investment policies that secure the social values of the Norwegian ... -
On the Ethics of Withholding and Withdrawing Unwarranted Diagnoses.
(Peer reviewed; Journal article, 2022)The number of diagnoses and the number of persons having diagnoses have increased substantially, and studies indicate that diagnoses are given or upheld even if they are unwarranted, that is, that they do not satisfy ... -
On the evaluation of ALD TiO2, ZrO2 and HfO2 coatings on corrosion and cytotoxicity performances
(Peer reviewed; Journal article, 2021)Magnesium alloys have been widely studied as materials for temporary implants, but their use has been limited by their corrosion rate. Recently, coatings have been proven to provide an effective barrier. Though only little ... -
On the Exchange Rate Dynamics of the Norwegian Krone
(Peer reviewed; Journal article, 2023)Global energy production is undergoing a transition from fossils to renewables. At the same time, the Norwegian Oil Fund has grown exponentially in size and is now a major global investor. These events in combination are ... -
On the exergy efficiency of CO<inf>2</inf> capture: The relation between sub-process and overall efficiencies
(Peer reviewed; Journal article, 2023)A generic exergy targeting tool for gas separation processes is developed, which is applicable to any defined boundary conditions for incoming feed gas as well as delivered separation products. Whereas targeting tools in ... -
On the Existence of Periodic Traveling Waves to the Whitham Equation
(Master thesis, 2015)We study the existence of periodic traveling waves to the Whitham equation, which is a nonlinear, nonlocal and dispersive differential equation proposed by Whitham as a model for surface gravity waves featuring the exact ... -
On the existence of step-to-step breakpoint transitions in accelerated sprinting
(Journal article; Peer reviewed, 2016)Accelerated running is characterised by a continuous change of kinematics from one step to the next. It has been argued that breakpoints in the step-to-step transitions may occur, and that these breakpoints are an essential ... -
On the External Effects Affecting Torsional Modes in Guide Vanes
(Journal article; Peer reviewed, 2019)Rotor stator interaction in high-head Francis turbines has led to several failures in recent years. Increasing efficiency demands require design optimization of the turbine components, which may lead to thinner profiles. ... -
On the Extraction and Analysis of Graphs From Resting-State fMRI to Support a Correct and Robust Diagnostic Tool for Alzheimer's Disease
(Journal article; Peer reviewed, 2018)The diagnosis of Alzheimer's disease (AD), especially in the early stage, is still not very reliable and the development of new diagnosis tools is desirable. A diagnosis based on functional magnetic resonance imaging (fMRI) ... -
On the fatigue and dwell-fatigue behavior of a low-density steel and the correlated microstructure origin of damage mechanism
(Peer reviewed; Journal article, 2021)The present work deals with revealing the fatigue and dwell-fatigue behavior and correlated damage mechanisms of Fe–Mn–Al–C lightweight steel. Surprisingly, alteration in loading mode from monotonic to cyclic induces ... -
On the fatigue properties of a third generation aluminium-steel butt weld made by hybrid metal extrusion & bonding (HYB)
(Peer reviewed; Journal article, 2021)The present investigation is concerned with the high-cycle axial fatigue behaviour of a third generation Al-steel butt weld made by hybrid metal extrusion & bonding (HYB). In this particular weld, metallurgical bonding is ... -
On the feasability of automatic segmentation with active contour models in image databases for shape extraction
(Master thesis, 2005)In this thesis the image segmentation system EDISON, was tested against an automatic version snake, which is an algorithm active contour models. The algorithms were tested against each to see if an automatic snake algorithm ... -
On the Feasibility of Fully Homomorphic Encryption of Minutiae-Based Fingerprint Representations
(Peer reviewed; Journal article, 2023)Protecting minutiae-based fingerprint templates with fully homomorphic encryption has recently been recognised as a hard problem. In this work, we evaluate state-of-the-art fingerprint recognition based on minutiae templates ... -
On the Feasibility of Real-time Sea Level Monitoring using Ground-based GNSS-Reflectometry Measurements
(Master thesis, 2020)GNSS Reflektometri (GNSS-R) er en fjernmålingsteknikk som har fått mye oppmerksomhet i nyere tid. I denne avhandlingen blir teorien bak GNSS reflektometri presentert, og et eksperiment er gjennomført for å vurdere mulighetene ... -
On the financial balance of input–output constructs: revisiting an axiomatic evaluation
(Journal article; Peer reviewed, 2016-04-11)Financial balance is fundamental to input–output analysis (IO), andconsequently the respect of this balance is one of the dominant criteria inevaluating IO constructs. Kop Jansen and ten Raa (1990) proved that ... -
