Maximum Available Power of Undersea Capacitive Coupling in a Wireless Power Transfer System
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-23)This paper studies the maximum available power of a dissipative capacitive power transfer (CPT) system submerged in seawater. The CPT system's maximum power capability is driven using the network theory, precisely the conjugate-image approach. The equations of the maximum available load power and the system's corresponding efficiency are expressed as a function of the capacitive coupling parameters. ... -
Arctic planktonic calcifiers in a changing ocean - A study on recent planktonic foraminifera and shelled pteropods in the Fram Strait-Barents Sea region
(Doctoral thesis; Doktorgradsavhandling, 2021-12-16)The Arctic marine realm is being transformed due to the anthropogenically-induced climate change. In the Arctic, the effects of climate change are intensified due to polar amplification and have led to processes in the ocean such as sea-ice retreat, ocean acidification and the increased presence of boreal species referred to as ‘Atlantification’. This thesis presents rare investigations of marine ... -
Self-Constructing Graph Convolutional Networks for Semantic Labeling
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-17)Graph Neural Networks (GNNs) have received increasing attention in many fields. However, due to the lack of prior graphs, their use for semantic labeling has been limited. Here, we propose a novel architecture called the Self-Constructing Graph (SCG), which makes use of learnable latent variables to generate embeddings and to self-construct the underlying graphs directly from the input features ... -
Throwing Pebbles While Waiting: An Autoethnographic Exploration of Mental Health and Colonialism

Real-Time Polyp Detection, Localization and Segmentation in Colonoscopy Using Deep Learning
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-04)Computer-aided detection, localization, and segmentation methods can help improve colonoscopy procedures. Even though many methods have been built to tackle automatic detection and segmentation of polyps, benchmarking of state-of-the-art methods still remains an open problem. This is due to the increasing number of researched computer vision methods that can be applied to polyp datasets. Benchmarking ... -
Chris Armstrong on Global Equality and Special Claims to Resources
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-29)In ‘Justice and Natural Resources,’ Chris Armstrong offers a rich and sophisticated egalitarian theory of resource justice, according to which the benefits and burdens flowing from natural (and non-natural) resources are ideally distributed with a view to equalize people’s access to wellbeing, unless there are compelling reasons that justify departures from that egalitarian default. Armstrong discusses ... -

Det legges fram data fra the Corpus of Young Learner Language som tyder på at en del 12–13-åringer overgeneraliserer formen are i presens, mens innlærere fra begge aldersgrupper overgeneraliserer was i preteritum. Mens overgeneraliseringa av are ... -
‘Northern, not Nordic noir’: A Norwegian case study on crime series and strategies for transnational television
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-01)This article discusses transnational television and what strategies public service broadcaster NRK Drama has pursued to make the Norwegian crime series Monster: Brutally Far North travel. Monster was the first Norwegian-language television series bought by a major American cable network, Starz. Using the concept of production values, we argue that NRK has made a series that is able to ride the Nordic ... -
Does international elite sporting success or hosting major events affect self-rated health? An examination of potential positive externalities related to international sporting tournaments
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-22)Research question: It is a common expectation among politicians, civil servants and sport managers that hosting a major sporting event or achieving international elite sport success yields a variety of positive externalities grounded in the “Virtuous Circle of Elite Sport and Events” model. However, over the years various studies have shown that this model is not necessarily an accurate depiction ... -

The medieval stockfish trade: a maritime perspective from northern Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021)Life in northern Norway has been dependent on the sea and marine resources since initial settlement following the retreating ice at least 11,500 years ago. Small islands have played a significant role for maritime communities since the Mesolithic when occupation of offshore islands reflected the maritime orientation of hunter‑gatherer settlement. Although settlement along the coast, including ... -
Heteronomi som forutsetning for autonomi
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-15)In his major works in ethics, Immanuel Kant (1724—1804) does not pay much attention to the question how humans become moral. The main tasks for Kant in these works are to establish the moral law and discuss its application. However, in his minor works in ethics and pedagogy he draws our attention to the question mentioned and claims that humans first become moral when they get 16 years old. Before ... -
