(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Given a Hopf algebra A graded by a discrete group together with an action of the same group preserving the grading, we define a new Hopf algebra, which we call the graded twisting of A. If the action is by adjoint maps, ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Continuing our previous work on graded twisting of Hopf algebras and monoidal categories, we introduce a graded twisting construction for equivariant comodule algebras and module categories. As an example we study actions ...

(Master thesis / Masteroppgave, 2011)There have been many reports on anomalies in the CMB from different research groups. In this work statistical tests using the gradients of the CMB temperature, applied to the seven year WMAP data, have been investigated. ...

(Master thesis / Masteroppgave, 2005)Denne oppgaven omhandler utviklingen av et grafisk verktøy for automatisk gruppering og degruppering av enkle dataorienterte UML- klassediagrammer. Grupperingen vil resultere i klasser som kan brukes som utgangspunkt for ...
-
(Doctoral dissertation / Doktoravhandling, 2015)In the wake of ‘the mobile revolution’ there has been an immense upsurge in mobile phone based health innovations, or mHealth for short. Expected efficiency gains and health benefits with such innovations, however, have ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Nanograins (≪1 μm) are common in the principal slip zones of natural and experimental faults, but their formation and influence on fault mechanical behavior are poorly understood. We performed transmission Kikuchi diffraction ...

(Master thesis / Masteroppgave, 2013)In situ weathering of the Mesoproterozoic, hornblende- and biotite-rich Rønne granite at Nygård kaolin pit provides a well preserved, Jurassic to Early Cretaceous saprolite section on Bornholm. Fresh Rønne granite could ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The study area is located in the Central Iberian Zone, a major tectonic unit of the Iberian Massif (Variscan belt). In this region the basement is composed of Cambrian-Ordovician sedimentary and minor volcanic rocks that ...

Granular viscosity from plastic yield surfaces: The role of the deformation type in granular flows (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Numerical simulations of granular flows with Navier–Stokes type models emerged in the last decade, challenging the well established depth-averaged models. The structure of these equations allows for extension to general ...

The granulite-eclogite facies transition as developed in the Bergen Arcs, with focus on the minerals scapolite and spinelRestricted Access (Master thesis / Masteroppgave, 2015)The Precambrian granulites (T~850°C and p<1.0 GPa) of the Lindås nappe, Bergen Arcs are transformed to Caledonian eclogites (T~670°C and p~1.8 GPa) in shear zones and along fluid pathways. This ...

(Master thesis / Masteroppgave, 2017)In this thesis the focus will be on the speed of light, and how one may reduce its impact on performance. For each remote invocation, there is an associated overhead that corresponds to the latency between the respective ...
-
(Master thesis / Masteroppgave, 2016)For a long time, the preferred machine learning algorithms for doing graph classification have been kernel based. The reasoning has been that kernels represent an elegant way to handle structured data that cannot be easily ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Graph-based representations are considered to be the future for reference genomes, as they allow integrated representation of the steadily increasing data on individual variation. Currently available tools allow de novo ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Graph products of groups were introduced by Green in her thesis [32]. They have an operator algebraic counterpart introduced and explored in [14]. In this paper we prove Khintchine type inequalities for general C⁎-algebraic ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)We discuss the internal structure of graph products of right LCM semigroups and prove that there is an abundance of examples without property (AR). Thereby we provide the first examples of right LCM semigroups lacking ...
