Dynamics of luffing motion of a flexible knuckle boom crane actuated by hydraulic cylinders
(Journal article; Peer reviewed, 2020)In this paper we present a modeling procedure for a flexible knuckle boom crane, which is actuated by hydraulic cylinders and is modeled as a planar multibody system. We propose a convenient framework where both rigid body ... -
Dynamics of Rigid and Flexible Manipulators Using Screw Theory
(Doctoral theses at NTNU;2020:8, Doctoral thesis, 2020)This thesis presents contributions within dynamic modeling of rigid and flexible open-chain holonomic multibody systems, as well as contributions in force analysis of such systems. Although application of the modeling and ... -

The earliest datable noctilucent cloud observation (Parma, Italy, AD 1840)
(Peer reviewed; Journal article, 2020)Noctilucent clouds (NLCs) are an uncommon phenomenon that provides information about the conditions and dynamics of the mesosphere. The first observation of NLCs was recorded in 1884/1885, following Krakatoa’s eruption in ... -
Early Detection of Subsurface Cracks in Rolling Element Bearings using the Acoustic Emission Time Series
(Master thesis, 2021)The formation and propagation of rolling contact fatigue (RCF) induced subsurface cracks (SSC) in a test specimen roller have been monitored using the acoustic emission time series. The sampled acoustic emission (AE) ... -
Early Detection of Subsurface Fatigue Cracks in Rolling Element Bearings by the Knowledge-Based Analysis of Acoustic Emission
(Journal article; Peer reviewed, 2022)Aiming at early detection of subsurface cracks induced by contact fatigue in rotating machinery, the knowledge-based data analysis algorithm is proposed for health condition monitoring through the analysis of acoustic ... -
Early Fault Detection of Wind Turbine Generator and Rotor Bearings
(Master thesis, 2023)Den bærekraftige energiomstillingen er avhengig av bruk av fornybare energikilder og vindturbiner spiller en sentral rolle. Feil diagnose og prognose for større feil i vindturbiner til havs og på land, som forårsaker lang ... -
An Early mid-Latitude Aurora Observed by Rozier (Beziers, 1780)
(Peer reviewed; Journal article, 2020)Aurora observations are an uncommon phenomenon at low and mid latitudes that, at the end of the 18th century, were not well known and understood. Low and mid geomagnetic latitude aurora observations provide information ... -
Early Phase Development of a Motorized Cross-Country Sit-Ski – Assistive Equipment for Para Sport Exercise
(Master thesis, 2020)Personer med fysisk funksjonsnedsettelse har ofte behov for hjelpemidler for å bruke skiløyper og nyte naturen. Staking i piggekjelke oppleves å være så anstrengende for brukerne at det begrenser utbredelsen av aktiviteten. For ... -
