The Ultrasound Cardiac Supercycle - for high temporal and spatial resolution
(Master thesis, 2021)Hjerteultralyd er en ikke-invasiv medisinsk avbildningsmetode som gir informasjon om hjertets struktur og funksjonsevne. Det er derav en mye brukt metode for å undersøke og oppdage hjerteog karsykdommer. Ettersom slike ... -
The Underwater Swimming Manipulator - A Bio-Inspired AUV
(Chapter, 2016)Autonomous underwater vehicles (AUVs) have been used for environmental mapping and surveys of various kinds for some time. More recently, the AUVs have entered the domain of the remotely operated vehicles (ROVs) to tackle ... -
The Underwater Swimming Manipulator — A Bioinspired Solution for Subsea Operations
(Journal article; Peer reviewed, 2018)Underwater vehicles have carried out subsea operations for many decades, and since the 1980s, remotely operated vehicles (ROVs) have been essential for the development and maintenance of subsea installations. As the ... -
The use of active noise control to reduce wind noise in motorcycle helmets
(Master thesis, 2019)Motorsykkelryttere som kjører på motorvei blir utsatt for vindstøy som kan vær på opptil 110 dB. Langvarig eksponering for støy kan føre til hørselstap, og støyen hindrer også rytteren i å plukke opp viktig trafikkstøy. ... -
The use of Model Predictive Control and Distributed Battery Energy Storage Systems for Primary Frequency Control
(Master thesis, 2014)Astheworldsenergydemandrisestogetherwithaglobalawarenessoverclimate-changesdue to burning of fossil fuel, and disasters due to accidents at nuclear power plants, thedemand for renewable energy grows. The two most available ... -
Theoretical Properties of Learning-based Model Predictive Control
(Doctoral theses at NTNU;2023:82, Doctoral thesis, 2023)Recently, the core idea of using Model Predictive Control (MPC) as a function approximator for the Reinforcement Learning (RL) methods has been proposed and justified. More specifically, it has been shown that a parameterized ... -
Thermal VSLAM for autonomous ferry
(Master thesis, 2021)Oppgaven presenterer en oversikt over ORB-SLAM1, 2 og 3, og viser implementering og tilpasninger av ORB-SLAM2 og ORB-SLAM3 for termisk video. Termisk VSLAM på autonome fartøy er motivert av et ønske om å gjøre navigasjonen ... -
Thermodynamics of a carbon nano-materials based icing protection system for unmanned aerial vehicle
(Chapter; Peer reviewed, 2016)Changes to the aerodynamic surfaces due to ice accretion are common causes for unmanned aerial vehicle (UAV) incidents in regions where the environmental conditions sustain icing conditions. For fixed wing UAVs the leading ... -
Threat Modeling Framework for Smart Grids
(Master thesis, 2021)Det fremtidige strømnettet, ofte kalt det smarte strømnettet, er forventet å inkludere distribuerte strømproduksjon, toveis flyt av strøm, omfattende innsamling og prosessering av data og et stort antall enheter relatert ... -
Three-Axis Motion Compensated Crane Head Control
(Master thesis, 2016)Offshore operations can be harsh and demanding and set personnel and equipment at risk. Ships will be exposed to the environmental forces of wind, waves and current, which will influence offshore crane operations considerably. ... -
