A Data Gathering System for the Arctic Tundra
(Mastergradsoppgave; Master thesis, 2024-06-02)Climate change has emerged as an important topic over the past decade, and one of the areas most susceptible to change is the Arctic Tundra. Monitoring the environment features a variety of challenges; it’s remote location, manual monitoring equipment and required permission to depart on expeditions. A solution to this is the use of a wireless sensor network to allow more automatic gathering ... -
Predicting the Destination Port of Fishing Vessels
(Mastergradsoppgave; Master thesis, 2024-06-02)Regulating the catch of fishing vessels is crucial for maintaining sustainable fish populations, preventing illegal fishing, and ensuring the quality of the fish being delivered. One effective method of controlling the catch is to have controllers physically present at the port where the catch is being delivered. However, vessels do not always report their destination port in a timely manner, which ... -
Large Language Models for Managing Online Fingerprint
(Mastergradsoppgave; Master thesis, 2024-06-01)Today, many are unaware of how much of their personal information is publicly available on the web, which has become an increasingly important issue among internet users. This thesis builds on the work of the preceding Capstone project and uses the open-source Online Privacy Pilot tool as a case study to explore how large language models can be incorporated into the tool to enhance its functionality ... -
Variable Dependency Graph Summarization
(Mastergradsoppgave; Master thesis, 2024-05-31)In personalized software, collected user data is used to give a tailored user experience. A user might be interested in understanding how their data (inputs) resulted in their personalized output. The Variable Dependency Graph (VDG) can explain how inputs of a program flow to the output. However, with increasing program size, there is a need for summarizing the VDGs and understanding these ... -
A before B: Investigations into how best to perform Temporal Health Queries
(Mastergradsoppgave; Master thesis, 2024-05-15)Querying and exploring health data can lead to the discovery of new rela- tions between conditions, medications, hospital events, etc. For this purpose, temporal health queries are useful since the order in which events happen is important.

Integrating and Validating Heart Health Calculators in Medical Platforms
(Mastergradsoppgave; Master thesis, 2024-05-15)We believe the underutilization of clinically validated algorithms for heart health assessment in current medical platforms undermines patient confidence in using associated screening instruments. The importance of earlier detection and improved health outcomes in heart disease motivated the development of these screening instruments. Available risk assessment tools are stand-alone online apps or ... -
Bevæpning av norsk politi - en analyse av risikoer knyttet til et ubevæpnet politi
(Master thesis; Mastergradsoppgave, 2024-06-30)Denne studien undersøker hvilke risikoer som er knyttet til at norsk politi går ubevæpnet i sin daglige tjeneste. Norsk politi er blant fåtallet av politistyrker i verden som ikke er fast bevæpnet, til tross for et endret trusselbilde de siste årene. Samtidig har terskelen for å få bevæpning på daglige oppdrag blitt senket, og det er flere midlertidige bevæpninger nå enn før. De siste årene har det ... -
