Functionally Generating Music Structures with Prefix Trees
(Master thesis, 2021)I dette prosjektet ble et nytt system for å generere musikk med fokus på struktur designet og implementert i det funksjonelle språket Haskell. Systemet representerer og genererer musikk med delt struktur på tvers av flerer ... -
Fundamental properties of snake robot locomotion
(Chapter, 2010)This paper presents a set of fundamental properties of the velocity of a snake robot conducting lateral undulation on a planar surface. In particular, the derived properties state that the average forward velocity of the ... -
Fusing Shape and Color for High-Speed Visual Tracking
(Master thesis, 2017)In a computer vision system, one must often assume that the system will encounter objects it has never seen before. A component that is able to track such objects is therefore an integral part of a complete computer vision ... -
Fusion between camera and lidar for autonomous surface vehicles
(Master thesis, 2018)The development of autonomous surface vessels (ASVs) has seen great progress in the last few years, and are on the verge of becoming a reality. Sensing the environment in a reliable way is a key element in making a ship ... -
Fusion of Inertial Navigation and Visual Odometry by Multi-State Constraint Kalman Filter
(Master thesis, 2017)The Multi-State Constraint Kalman Filter for visual-inertial odometry with online estimation of extrinsic and intrinsic camera parameters using the fisheye camera model is presented, and its performance in terms of accuracy ... -
Fusion of Visual-Inertial Odometry and GNSS-Based Positioning for Localization of Autonomous Ferries
(Master thesis, 2022)Selvlokalisering for autonome systemer er helt essensielt for å kunne operere uten tilsyn. For droner og andre høyhastighetsfartøy så er visuell-treghetsbasert odometri (Visual-Inertial Odometry) et godt alternativ. I denne ... -
Fuzzy domain and meta-heuristic algorithm-based collision avoidance control for ships: Experimental validation in virtual and real environment
(Peer reviewed; Journal article, 2020)Collisions at sea are frequently caused by human-related factors, such as; manoeuvre timing mistakes, risk assessment failures and deficiencies in strategies for collision avoidance. These factors reveal the importance of ... -
Gain Scheduled Controller with Bumpless Transfer for an Unmanned Surface Vehicle
(Master thesis, 2019)Denne masteroppgaven er basert på prosjektoppgaven “Systemidentifikajson av et ubemannet overflatefartøy med to faste propeller”. Prosjektoppgaven legger frem en metode for å finne modellparameterne til en autopilotmodell ... -
Gain-scheduled steering control for a wave-propelled unmanned surface vehicle
(Peer reviewed; Journal article, 2022)The persistent observation of oceanographic phenomena is nowadays hampered by technological limitations, that prevent marine robotic platforms to autonomously execute scientific surveys for extended periods of time. The ... -
GANs enabled super-resolution reconstruction of wind field
(Peer reviewed; Journal article, 2020)Atmospheric flows are governed by a broad variety of spatio-temporal scales, thus making real-time numerical modeling of such turbulent flows in complex terrain at high resolution computationally unmanageable. In this ... -

Gas Lift Optimization Using Python and Prosper Well Models
(Master thesis, 2022)Arbeidet utført i denne masteroppgaven har hatt som mål å maksimere produksjon av olje innenfor begresninger på trykk, gassløftrate og andre prosessbegrensninger. Brønn-modellen, som beskriver oppførselen til en brønn når ... -
Gate controlling MPCs as Part of a cascaded MPC Structure, used for harmonic Mitigation in a Ship Power System
(Master thesis, 2018)This thesis studies the effect of controlling gate switches in an APF using FCS-MPC. This gave a cascaded MPC structure. Where internal states and a calculated reference from the first MPC is used by a second MPC. The ... -
Gaussian Field Current Estimation from Drift Sea Ice Tracking with the Labeled Multi-Bernoulli Filter
(Chapter, 2017)In polar region operations, drift sea ice positioning and tracking is useful for both scientific and safety reasons. Modeling ice movements has proven difficult, not least due to the lack of information of currents and ... -
Gaussian Processes for long-term trajectory prediction using historical AIS data
(Master thesis, 2021)For at autonome overflate-fartøyer (ASVer) skal kunne operere trygt er det essensielt med robuste antikollisjonssystemer. Slike systemer innebærer ikke bare at et fartøy må kunne reagere i det det oppstår farlige situasjoner, ... -
