As Geographic Information Systems (GISs) increasingly migrate to the web, efficiently delivering high-resolution datasets for interactive visualization pre-sents a substantial challenge. In this thesis, we propose a shaver, a novel compression system tailored for Web-Based GIS platforms, combining unstructured grid simplification with state-of-the-art lossy floating-point compression. Building on ...

Marine oil spills require constant monitoring as they can cause severe environmental damage. Synthetic Aperture Radar (SAR) images are often used for oil spill detection, but they are complex and the analysis is a time-consuming process as there are a lot of areas to monitor. Therefore, the manual analysis of the images will inevitably lead to some errors. Deep learning models can be deployed for ...

I denne masteroppgaven har jeg undersøkt hvordan elever på 9. trinn arbeider med matematisk generalisering gjennom å gi elever mønsteroppgaver. Resultater fra PISA 2022 viser at norske elever aldri har scoret lavere i PISA-undersøkelsen innen kunnskapsområdet matematikk og at en betydelig større andel norske elever presterer på lavt nivå i matematikk enn tidligere. Kun sju prosent av elevene havner ...

Denne studien har undersøkt hvordan piloter i Widerøe forstår og anvender begrepet unfit. Studien benyttet en kvantitativ tilnærming med en spørreundersøkelse besvart av 104 Widerøe-piloter (21 % av utvalget). Hele 62,5 % av respondentene oppgir at de i løpet av de siste 24 månedene har vært på jobb i situasjoner hvor de i ettertid eller underveis tenkte at de burde meldt seg unfit. Årsakene er ...

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 ...
