In unmanned aerial vehicle (UAV) flights, power lines are considered as one of the most threatening hazards and one of the most difficult obstacles to avoid. In recent years, many vision-based techniques have been proposed to detect power lines to facilitate self-driving UAVs and automatic obstacle avoidance. However, most of the proposed methods are typically based on a common three-step approach: ...

Purpose - Heat-and-moisture-exchanging devices (HME) are commonly used by endurance athletes during training in sub-zero environments, but their effects on performance are unknown. We investigated the influence of HME usage on running performance at − 15 °C.<p> <p>Methods - Twenty-three healthy adults (15 male, 8 female; age 18–53 years; V˙O_2peak men 56 ± 7, women 50 ± 4 mL·kg<sup>−1 ...

We study how some coefficients of two-variable coboundary polynomials can be derived from Betti numbers of Stanley–Reisner rings. We also explain how the connection with these Stanley–Reisner rings forces the coefficients of the two-variable coboundary polynomials and Möbius polynomials to satisfy certain universal equations.

This paper contributes to the recent literature on sustainability in the Arctic as a political concept. Parliamentary proceedings have increasingly been recognized as an important source of information for eliciting political issues. In this paper, we use unsupervised text mining techniques to analyze parliamentary speeches for Norway from the period from 2009 to 2016 to answer whether political ...

<p>Denne avhandlingen er et bidrag til å forstå hva som skjer når en ny teknologi trer inn i skolekonteksten. Avhandlingens forskningsfokus vokste ut av et behov for kunnskap om hvordan teknologi faktisk organiseres i skolen, hva læreres profesjonsfaglige digitale kompetanse (PfDK) vil si i praksis, og en ambisjon om å tilføre nye teknologiforståelser på feltet. Studien som avhandlingen bygger på ...

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 ...

In this article, three scholars jointly investigate questions of Western colonization and mental health. While their areas of interest and experience vary, the authors discuss oppression as a common thread connecting their ideas about mental health and its medicalization. In line with Toyosaki et al. (2009), the researchers did a community autoethnography, performing written dialogue as a dynamic ...

Purpose - The purpose of this study is to further paradox research at the individual level through applying a framework of three phases of individual response to paradox – recognition, understanding and behaviour.<p> <p>Design/methodology/approach - Critical and integrative review of previous studies of individual responses to paradox.<p> <p>Findings - The role of individual understanding is ...

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 ...

Artikkelen diskuterer tilegnelsen av samsvarsbøyning (mellom subjekt og verbal) ved be i engelsk blant 12–13- og 15–16-åringer med norsk språkbakgrunn. 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 ...
