A new method for measuring free-ranging fish swimming speed in commercial marine farms using Doppler principle
(Journal article; Peer reviewed, 2020)A novel Doppler shift based technique for measurement of free-swimming fish speed in marine farms using acoustic telemetry tags was developed and evaluated in this study. The proposed method can potentially augment current ... -
New prototype for an Autonomous Icing Protection Solution (AIPS) for Unmanned Aircrafts - Employing aviation standards for UAV systems
(Master thesis, 2017)Icing hazards pose a risk to all of aviation, including the use of unmanned aircrafts. Ice accumulation on the forward facing surfaces of an aircraft changes the dynamic properties of the vehicle, which drastically increases ... -
New Results on Trajectory Planning for Underactuated Mechanical Systems with Singularities in Dynamics of a Motion Generator
(Journal article; Peer reviewed, 2018)The new approach to the problem of motion planning for underactuated mechanical systems is proposed. The novelty comes from new opportunities to handle singularities of the dynamics of the motion generator provided that ... -

(Bachelor thesis, 2023)Denne oppgaven forklarer utviklingsprosessen for en håndgrepstrener som kan samle inn målinger, loggføre data og nøyaktig beskrive grepets dynamikk. Dette betyr at den utviklede håndgrepstreneren må være i stand til å måle ... -
NFA-grillen: Solenergidrevet automatisert pølsegrill
(Master thesis, 2010)Norsk Forening for Automatisering endret i 2009 sin visjon til ?Gjøre automatiseringtil et hovedtema i det offentlige rom.? Formålet med NFA-grillener å fremme visjonen om å gjøre automatisering til et hovedtema i det ... -
Non-Intrusive Load Monitoring with Norwegian Smart Meters
(Master thesis, 2018)The smart meters to be installed in Norway by 2019 is thought to open up for a more efficient and flexible power grid and have so far cost the Norwegian distribution system operators(DSO) well over 10 Billion NOK, an ... -
Non-invasive sensor fusion for improved meal detection.
(Master thesis, 2021)For diabetespasienter vil økt pålitelighet og/eller minsket deteksjontid for automatisk identifisering av måltider være fordelaktig når insulin skal doseres. En tidligere og mer pålitelig indikasjon på at et måltid er ... -
Non-linear model predictive control for an oil production network based on gas-lift
(Master thesis, 2014)Control and optimization of an oil production network based on gas-lift is a difficult task with challenges including well fluid flow oscillations and pipeline slugging which can lead to instabilities in the system. A ... -
Non-Linear Model Predictive Control for Modular Multilevel Converters
(Chapter, 2022)In this paper, non-linear model predictive control (NMPC) without an explicit modulator is applied to modular multilevel converters (MMCs) in the abc reference frame. NMPC can easily be extended for longer prediction ... -
