Localization and Tracking of Ships and Objects Using a UAV Mounted Thermal Imaging Camera.
(Master thesis, 2015)This thesis presents the creation of a payload system for a small unmanned aircraft, which is used for data collection and testing of detection and tracking theory. Theory for position estimation of on-ground or on-sea ... -
Localization for Ships and Ferries During Harbour Maneuvering and Docking
(Master thesis, 2022)Abstract will be available on 2025-06-06 -
Localization for Ships during Automated Docking using a Monocular Camera
(Chapter, 2022)Automating docking operations of ships requires at least two robust and precise localization systems for reaching the typically required safety and redundancy levels. Global navigation satellite systems are typically chosen ... -
Localization of a Floating Buoy in a Fish Farming Pen
(Master thesis, 2016)This thesis proposes a solution to localize a floating buoy in a fish farming pen. The task is provided by Stingray Marine Solutions and is meant to be an integrated part of their optical delousing system. The solution ... -
Localization of Active Brain Sources From EEG Signals Using Empirical Mode Decomposition: A Comparative Study
(Journal article; Peer reviewed, 2018) -
Localization of an Acoustic Fish-Tag using the Time-of-Arrival Measurements: Preliminary results using eXogenous Kalman Filter
(Journal article; Peer reviewed, 2018)This paper addresses the source localization problem of an acoustic fish-tag using the Time-of-Arrival measurement of an acoustic signal, transmitted by the fish-tag. The Time-of-Arrival measurements denote the pseudo-range ... -

Locomotion Efficiency of Underwater Snake Robots with Thrusters
(Chapter, 2016)Lately there has been an increasing interest for subsea inspection and intervention tasks, and in particular on solutions which combine smaller size, increased flexibility and maneuverability, and decreased cost. Biologically ... -
Locomotion efficiency optimization of biologically inspired snake robots
(Journal article; Peer reviewed, 2018)Snake robots constitute bio-inspired solutions that have been studied due to their ability to move in challenging environments where other types of robots, such as wheeled or legged robots, usually fail. In this paper, we ... -
Long range path planning using an aircraft performance model for battery powered sUAS equipped with icing protection system
(Journal article, 2020)Earlier studies demonstrate that en-route atmospheric parameters, such as winds and icing conditions, significantly affect the safety, and in-flight performance of unmanned aerial systems. Nowadays, the inclusion of ... -
A long short term memory for hybrid uplifted reduced order models.
(Peer reviewed; Journal article, 2020)In this paper, we introduce an uplifted reduced order modeling (UROM) approach through the integration of standard projection based methods with long short-term memory (LSTM) embedding. Our approach has three modeling ... -
Long short-term memory embedded nudging schemes for nonlinear data assimilation of geophysical flows
(Peer reviewed; Journal article, 2020)Reduced rank nonlinear filters are increasingly utilized in data assimilation of geophysical flows but often require a set of ensemble forward simulations to estimate forecast covariance. On the other hand, predictor–corrector ... -
A long simulation scenario for evaluation of multi-target tracking methods
(Chapter, 2023)Algorithms for multi-target tracking are typically evaluated by means of simulations. Typically, the simulated scenarios are fairly short and of very simple geometry. In contrast, this paper describes a scenario which was ... -
Long-Horizon Informative Path Planning with Obstacles and Time Constraints
(Peer reviewed; Journal article, 2022)We apply non-myopic informative path planning in a simulated river plume case study with several constraints on our agent. A cost valley philosophy is proposed to guide the agent through the field. The purpose of this path ... -
Long-term Vessel Prediction Using AIS Data
(Master thesis, 2018)In recent years there has been much research dedicated to the development of autonomous surface vehicles (ASVs), including large-scale autonomous ships. An important part of this research is to ensure that an ASV can safely ... -
Longitudinal Moving Mass Actuation of Fixed-Wing Unmanned Aerial Vehicle (UAV)
(Master thesis, 2021)Bevegelig masseforflytting er en kontrollmekanisme som erstatter aerodynamiske kontrollflater, som høyde-, balanse- og sideror for et fly ved å bruke interne mobile masser til å endre tyngdepunktet. Metoden muliggjør et ... -
Loopy belief propagation for marginal association probabilities in multiple hypothesis tracking
(Master thesis, 2023)Nyere resultater innenfor målfølging av flere mål med kun én hypotese bruker ``loopy belief propagation'' (LBP) for å utføre effektiv, tilnærmet marginalisering av hypoteseposterioren med stor suksess. Denne avhandlingen ... -
LOS Path Following for Underactuated Underwater Vehicle
(Journal article, 2006)In this paper, we propose a control scheme for path following of underactuated underwater vehicles. In particular, we propose a guidance law based on the the well-known principle of Line of Sight (LOS) guidance that is ... -
Low Altitude Georeferencing for Imaging Sensors in Maritime Tracking
(Peer reviewed; Journal article, 2020)This paper presents a method for georeferencing low-altitude camera sensors, both infrared and electro-optical, in a maritime context. Accurate georeferencing require very high precision for the object pixel coordinates ... -
Low complexity constrained control using higher degree Lyapunov functions
(Journal article; Peer reviewed, 2018)Explicit Model Predictive Control often has a complex solution in terms of the number of regions required to define the solution and the corresponding memory requirement to represent the solution in the online implementation. ...
