On the effect of topography and wind on warm water inflow— An idealized study of the southern Weddell Sea continental shelf system
(Peer reviewed; Journal article, 2017-03)An idealized eddy-resolving numerical model, with topographic features common to the southern Weddell Sea, is constructed to study mechanisms through which warm deep water enters a wide continental shelf with a trough. The ... -
On the effectiveness of the incremental approach to minimal chordal edge modification
(Journal article; Peer reviewed, 2021)Because edge modification problems are computationally difficult for most target graph classes, considerable attention has been devoted to inclusion-minimal edge modifications, which are usually polynomial-time computable ... -
On the energy stability of high-order finite volume schemes for initial-boundary value problems
(Master thesis, 2023-06-01)We examine the energy stability of high-order finite volume schemes approximating linear hyperbolic initial- boundary value problems. In particular, we consider schemes obtained by the k-exact method and the spectral volume ... -
On the evolution of the North Atlantic -from continental collapse to oceanic accretion
(Doctoral thesis, 2013-10-23)The North Atlantic between Iceland and Svalbard and surrounding continental areas represent an ideal laboratory for studying plate tectonic processes, due to the presence of well exposed continent-continent collision ... -
On the existence of optimal controls for a singular stochastic control problem in finance.

On the extension giving the truncated Witt vectors
(Master thesis, 2015-01-05)We explore the theory of cohomology of groups and the classification of group extensions with abelian kernel. We then look at the group extensions that underlie the truncated Witt vectors on the truncation set {1,p} where ... -
On the feasibility of distributed systems for interactive visual analysis of omics data
(Master thesis, 2014-06-02)The purpose of this thesis is to discuss the feasibility of developing a distributed interactive visual analysis omics system demonstrating how selected modules from the standalone J-Express Modularized application can be ... -
On the formation of coastal rogue waves in water of variable depth
(Journal article; Peer reviewed, 2023)Wave transformation is an intrinsic dynamic process in coastal areas. An essential part of this process is the variation of water depth, which plays a dominant role in the propagation features of water waves, including a ... -

On the Formulation of Mass, Momentum and Energy Conservation in the KdV Equation
(Peer reviewed; Journal article, 2014-10)The Korteweg-de Vries (KdV) equation is widely recognized as a simple model for unidirectional weakly nonlinear dispersive waves on the surface of a shallow body of fluid. While solutions of the KdV equation describe the ... -
On the Freshwater Transport in the Fram Strait
(Doctoral thesis, 2023-11-03)Ferskvann fra Arktisk er en nøkkelparameter i det globale klimasystemet. Arktisk ferskvann har sin opprinnelse fra nedbør eller havis-smelting, og konsentrasjonen av det i havet varierer på flere tidsskalaer. Økningen i ... -
On the future of Argo: A global, full-depth, multi-disciplinary array
(Peer reviewed; Journal article, 2019-08-02)The Argo Program has been implemented and sustained for almost two decades, as a global array of about 4000 profiling floats. Argo provides continuous observations of ocean temperature and salinity versus pressure, from ... -

On the Groupiness and Intermittency of Oceanic Whitecaps
(Journal article; Peer reviewed, 2022)The enhancement of wave breaking activity during wave group passage is investigated using coherent field observations of the instantaneous sea surface elevation and whitecap coverage from platform-based stereo video ... -
On the Hardness of Generalized Domination Problems Parameterized by Mim-Width
(Journal article; Peer reviewed, 2022)For nonempty σ, ρ ⊆ ℕ, a vertex set S in a graph G is a (σ, ρ)-dominating set if for all v ∈ S, |N(v) ∩ S| ∈ σ, and for all v ∈ V(G) ⧵ S, |N(v) ∩ S| ∈ ρ. The Min/Max (σ,ρ)-Dominating Set problems ask, given a graph G and ... -
On the High‐Energy Spectral Component and Fine Time Structure of Terrestrial Gamma Ray Flashes
(Journal article; Peer reviewed, 2019)Terrestrial gamma ray flashes (TGFs) are very short bursts of gamma radiation associated to thunderstorm activity and are the manifestation of the highest‐energy natural particle acceleration phenomena occurring on Earth. ... -
On the Impact of a Streaming Oxygen Population on Collisionless Magnetic Reconnection
(Journal article; Peer reviewed, 2020)Using 2.5-D Particle-In-Cell (PIC) simulations, we investigate how magnetotail reconnection is affected by a cold, streaming, oxygen plasma population, attributed to an ionospheric source, in the inflow region. As the ... -
On the importance of temperature and precipitation changes for glacial ice sheet stability
(Master thesis, 2023-11-20)Ice sheets undergo periodic advances and retreats, resulting in glacial-interglacial cycles. The Last Glacial Period is widely believed as involving a long-time buildup phase followed by a rapid termination over approximately ... -
On the IND-CCA1 Security of FHE Schemes
(Journal article; Peer reviewed, 2022)Fully homomorphic encryption (FHE) is a powerful tool in cryptography that allows one to perform arbitrary computations on encrypted material without having to decrypt it first. There are numerous FHE schemes, all of which ... -
On the Influence of Latent and Sensible Heating for Maintaining Baroclinicity in the Gulf Stream Region
(Master thesis, 2016-06-01)For the North Atlantic storm track to collocate with the ocean front, there has to be efficient restoring mechanisms for baroclinicity. The total diabatic heating is agreed to play the most dominant role, but whether the ...
