Optimal Positioning for Transceivers in Network
(Master thesis; Mastergradsoppgave, 2024-05-22)This thesis investigates the use of optimization techniques to configure a network of short-range transceivers for best coverage of a topographic layer. Three methods are presented, tested, and analysed. The thesis is inspired by the limited range of underwater wireless communication transceivers. The coverage is defined by free "Line of Sight" (LOS) and a 100 meter transceiver range. The terrain ... -

UAV as an inspection tool for power lines in Troms: Assessment of UAVs as a viable alternative to already established methods for inspection of power lines.
(Master thesis; Mastergradsoppgave, 2018-06-02)Power line inspection is one of the most important things in a modern society, and therefore it is important that it be kept in a functional state. Because of this, many methods are used to keep it that way. There are many factors to consider before using UAVs as a viable alternative to already established methods. Factors such as robustness against harsh weather, limits to its range and battery ... -
Segmentation of Polar Mesospheric Summer Echoes using Fully Convolutional Network
(Master thesis; Mastergradsoppgave, 2023-04-26)Polar Mesospheric Summer Echoes (PMSE) are strong coherent radar echoes that occur in the 80 to 90 km altitude range of the mesosphere during the Arctic summer months. These echoes are of significant interest to the space physics community as they provide insight into changes that occur in the atmosphere. To better understand these changes, large datasets of PMSE echoes need to be analysed. In ... -
Snow detection on antenna radomes using signal processing
(Master thesis; Mastergradsoppgave, 2022-06-25)Radomes are dome-shaped covers that protect the antenna from the climate, such as rain, wind, sunlight, and snow. Even though the radomes protect the antenna from snow and ice, it does not prevent snow and ice from building up on the radome. When snow and ice build up enough on the radome, the signal passing through it loses strength. This project tries to detect snow and ice build-up on antenna ... -
Vessel operations in relation to new types of offshore aquaculture facilities, and weather windows in exposed areas
(Master thesis; Mastergradsoppgave, 2022-06-01)The marine aquaculture industry is expanding the production into new sea areas. The technology is advancing, and offshore aquaculture facilities are being developed. The offshore developments can offer significant benefits that applies to the economy, optimization of operations and production, as well as minimizing the impact on the coastal areas. Structural and operation procedures need to be ... -
Implementation of Virtual Reality (VR) simulators in Norwegian maritime pilotage training
(Master thesis; Mastergradsoppgave, 2022-06-01)With millions of tons of cargo transported to and from Norwegian ports every year, the maritime waterways in Norway are heavily used. The high consequences of accidents and mishaps require well-trained seafarers and safe operating practices. The normal crews of vessels are supported by the Norwegian Coastal Administration (NCA) pilot service when operating vessels not meeting specific ... -
Investigation of UAV related incidents and accidents
(Master thesis; Mastergradsoppgave, 2022-05-30)To this day, there is a lack of research on unmanned aerial vehicle (drone) related incidents and accidents. Knowing why these happen, what potential outcomes they may have and how to avoid them from occurring, can be crucial. There is, furthermore, potentially a lack of transparency in the unmanned aviation industry, regarding reporting of incidents. In order to prepare conclusions within one set ... -
Preventing Atmospheric Icing in Aviation: Passive Repulsion of Super Cooled Water Droplets through Hydrophobic Nanocomposites
(Master thesis; Mastergradsoppgave, 2020-07-13)The aviation industry already consists of a complex system of strict regulations related to operation and maintenance, where severe weather conditions further challenge flight operations. Recent research has shown that most aircraft accidents are caused by icing externally, where severe icing conditions lead to the critical degradation of the aerodynamic effectiveness – increasing the stall speed. ... -
Limitations of Ice Accretion on Offshore Aquaculture Facilities
(Master thesis; Mastergradsoppgave, 2021-12-15)Sea spray icing is a constant risk for fish farms operating in cold climates, such as on the Northern Norwegian coast, and there must therefore exist methods to reduce this risk. This thesis discusses the consequences of ice accretion to the traditional plastic circular fish cage design, and how the cage reacts under the pressure of added mass from sea spray icing. The prediction of sea spray icing ... -

Roll motion on small traditional Norwegian fishing vessels
(Master thesis; Mastergradsoppgave, 2021-08-09)Roll motion is one of the six degrees of freedom and is the most difficult to predict, as roll motion is extremely sensitive to the viscous effect and induced flow separation. The smaller fishing vessel fleet commonly operates in almost all weather conditions, and sometimes in remote areas with cold arctic water where rescue can be far away and difficult. The safety of fishers depends on the vessel's ... -
