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 ... -
Software Defined Radio Based Avalanche Beacon Receiver
(Master thesis; Mastergradsoppgave, 2024-01-24)Annually, avalanches claim an average of 100 lives, and many more are injured. For victims buried by an avalanche, time is of the essence. If not rescued within 15 minutes, the victim only has a 10% probability of survival. Commonly, the people venturing into avalanche-prone areas equips avalanche beacons. These devices work as small radio transmitters transmitting a signal at 457 kHz once each ... -
Enhancing Prediction of Blast-Induced Ground Vibrations through Machine Learning
(Mastergradsoppgave; Master thesis, 2024-01-12)This Master’s thesis investigates the application of Machine Learning (ML) in predicting blast-induced ground vibrations in mining, with the aim of sur- passing the precision of the current industry-standard model that utilizes an empirical, regression-based method. The study applied a Deep Neural Network (DNN) model, selected for its capability to consider a broader range of variables than the ... -
Aquilier: An Ethereum-Based Smart Contract for Door-Lock Management in Home Assistant
(Mastergradsoppgave; Master thesis, 2023-12-15)The widespread adoption of distributed computer systems, exemplified by plat- forms like Airbnb and Booking.com, has transformed homes into rental proper- ties and streamlined vacation rentals by offering comprehensive tools for listing properties, processing payments, facilitating searches, and enabling communi- cation. However, a critical gap remains: these platforms do not facilitate ... -
User-Aware Conflict Resolution
(Master thesis; Mastergradsoppgave, 2023-06-26)A large-scale system that prioritizes high availability over extensive synchroniza- tion must make a design trade-off and implement a weaker form of consistency. Conflict-free Replicated Data Types(CRDTs) can enable replicas in the sys- tem to communicate asynchronously and achieve strong eventual consistency. SynQLite aims to implement CRDTs on top of relational databases with its addition of ... -
