Polar lows can pose serious threats to maritime operations and coastal communities in polar regions, especially due to their extreme wind speeds. The accurate and reliable representation of their wind field thus plays a crucial role in forecasting and mitigating the risks associated with this phenomenon. This study aims to evaluate the value of the SAR-based Sentinel-1 Ocean Wind Field product ...

Arctic ship traffic has increased significantly due to continuous sea ice loss and resource extraction. The shipping sector is an important contributor to atmospheric emissions of nitrogen oxides (NO_x) and sulphur dioxide (SO₂), and an increase in ship activity will lead to significant increases in these emissions. However, there is a lack of studies linking ship activities and ...

Denne kvalitative studien handler om å undersøke hvorvidt et undervisningsopplegg som vektlegger sammenhengen mellom geometri og algebra i løsning av andregradslikninger, bidrar til at elevene sitter igjen med strukturforståelse av løsningsmetoden, abc-formelen. Hensikten med oppgaven var å planlegge og gjennomføre et annerledes undervisningsdesign innenfor temaet andregradslikninger i en ...

This paper addresses the crucial task of power line detection and localization in electrical infrastructure inspection using Unmanned Aerial Vehicles (UAVs) from weak supervision, polyline annotations. We first identify several limitations in the state-of-the-art approach LSNet. In particular, the inability of LSNet to detect line-crossings and lines in close proximity. To overcome these limitations, ...

In the last decades, material discovery has been a very active research field driven by the need to find new materials for many different applications. This has also included materials with heavy elements, beyond the stable isotopes of lead, as most actinides exhibit unique properties that make them useful in various applications. Furthermore, new heavy elements beyond actinides, collectively referred ...

Nearest neighbor (NN) sampling provides more semantic variations than predefined transformations for selfsupervised learning (SSL) based image recognition problems. However, its performance is restricted by the quality of the support set, which holds positive samples for the contrastive loss. In this work, we show that the quality of the support set plays a crucial role in any nearest neighbor based ...

The present paper is a data note related to the paper “Gender perspectives on a flipped classroom environment”. The paper drew on an in-depth analysis of the interview with a single female student called Sofia and attempted to analyze different gender related interactions between students in group work situations experienced by this student. The transcript from this interview was translated from ...

Many media providers offer complementary prod-ucts on different platforms to target a diverse consumer base. Online sports coverage, for instance, may include professionally produced audio and video channels, as well as Web pages and native apps offering live statistics, maps, data visualizations, social commentary and more. Many consumers also engage in parallel usage, setting up streaming products ...

Liquid injection optimization is key to enhance the efficiency of many processes in a wide variety of fields. Combustion processes are one of the most challenging ones, due to the direct emissions and greenhouse gases implications. This work aims at studying the external two-phase flow produced when injecting fuel with a pressure-swirl atomizer in an operating condition typical of an academic ...

Denne oppgaven viser at det er mulig å gjøre differensiell fotometri av ∂-Scuti stjerner med rimelig god presisjon ved Skibotn observatorium. Den høyeste presisjonen som ble oppnådd i C1-C2 var 28 mmag. Sammenligningen av den beste natten fra Skibotn med en god natt fra FG Vir kampanjen (året før) viser at muligheten er til stede for å oppnå gode resultater. En bekreftelse på dette fikk vi da to av ...
