At 04:01 on November 8th, 2018, the Norwegian frigate HNoMS Helge Ingstad collided with the tanker Sola TS near the Sture Terminal in the Hjeltefjord, eventually sinking. Of the 137 crew members, seven sustained minor injuries. While initial media attention focused on the collision, it later shifted to the legal proceedings. A single individual was convicted, with findings from the Accident Investigation ...

Paleoclimate proxy records such as marine sediment cores are crucial for understanding past climate conditions. The deposition rate for these archives may vary dramatically both within individual cores and between them, obfuscating the temporal expression of events. Accurate alignment of cores is therefore critical for determining extent and rate of past climate change. Current methods are performed ...

Økt elektrifisering av samfunnet har ført til høyere belastning og dermed ført til et økt behov for fleksibilitet i strømnettet. Varmtvannsberedere er et standard husholdningsapparat som finnes i de aller fleste husholdninger i Norge. Varmtvannsberedere er den vanligste formen for termisk lagring. Ved å utnytte den termiske lagringskapasiteten kan man flytte strømforbruket til lavlastperioder. Denne ...

There is limited documentation of complete surge cycles from Svalbard. Since the Little Ice Age, multiple surge-type glaciers in Svalbard have been undergoing continuous retreat. This has led to the formation of combined terrestrial and marine terminating margins, as well as newly exposed terrain, featuring glacial landforms such as crevasse-squeeze ridges, which are diagnostic landforms of surge-type ...

This thesis presents Joavku, a lightweight and interpretable system for performing automated team assignment of football players using only visual data. Unlike many existing systems that rely on custom-trained machine learning models or external tracking technologies, Joavku utilizes a novel color-based classification method that identifies the dominant team color in a player’s kit. By isolating key ...

Dynamic positron emission tomography (dPET) imaging requires an accurate arterial input function (AIF) for quantitative analysis. However, traditional methods for AIF measurement require invasive blood sampling. Recent deep learning models can predict the AIF from the 4D PET data itself, eliminating the need for invasive blood sampling. However, their performance often degrades with limited amount ...

Accurate and fast oil spill detection is crucial to enable effective usage of mitigation resources to minimize environmental damage. Synthetic Aperture Radar (SAR) imagery provides a reliable means of large-scale ocean monitoring, but analyzing these images remains a time-consuming and labor-intensive task. The presence of lookalikes in SAR images, natural phenomena imitating the appearance of oil ...

This thesis presents a novel implementation of a Non-Interactive Key Exchange (NIKE) protocol using features from Attribute-Based Encryption (ABE) to achieve a highly space-efficient key distribution scheme. Our Token-Based Key Exchange (TBKE) implementation enables scalable symmetric key generation through compact, capability-based tokens, making it particularly suited for resource-constrained ...

During the summer months at high and mid-latitudes, VHF and UHF radars can detect strong radar echoes, known as Polar Mesospheric Summer Echoes (PMSE), at altitudes between 80 and 90 km. The formation of PMSE is closely linked to the presence of ice particles, turbulence, and irregularities in the electron density. Current theories suggest that neutral turbulence causes the spatial structuring of ...

The physical environment of the northern Barents Sea is shaped by the inflow of warm, saline Atlantic Water (AW) and the seasonal cycle of sea ice. Recent years have seen a rapid shift toward more Atlantic conditions, driven by reduced sea ice import and increased influence of AW intrusions. Although seasonal variability is crucial for understanding these changes, observations from the ice-covered ...
