Computer Vision for Automatic Assessment of Fish Mortality Causes in Commercial Fish Farms
(Master thesis, 2023)Denne masteroppgaven er utarbeidet med hensikt å bidra til å lage en fotoboks for analyse av dødfisk ved hjelp av datasyn fra oppdrettsanlegg for laks. Dagens forskning har i liten grad viet oppmerksomhet til dypere ... -
Computer vision for quality grading in fish processing
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:244, Doctoral thesis, 2007)High labour costs, due to the existing technology that still involves a high degree of manually based processing, incur overall high production costs in the fish processing industry. Therefore, a higher degree of automation ... -
Computer Vision-Based Infant Movement Assessment
(Doctoral thesis at NTNU;2016:22, Doctoral thesis, 2016)The aim of this thesis is to develop an objective predictive model for cerebral palsy based on video recording of spontaneous movements of young infants. In the recent years, computer-based motion assessment methods have ... -
Computer Vision-Based Robot Control For Lobster Identification and Tracking
(Master thesis, 2020)Europeiske hummere er høyt verdsatt og har en høy pris, men i de siste tiårene har intensiv akvakultur produksjon av hummere vist seg å være vanskelig å gjennomføre. En vanlig egenskap hos hummere er agnostisk oppførsel ... -

Condition Monitoring of Hydroelectric Power Plants
(Master thesis, 2018)Much research can be found on condition monitoring for many industries. There are, however, very little research on the use of condition monitoring in hydroelectric power plants. A literature search investigates this field, ... -
Condition Monitoring of Mechanical Equipment Using Bilinear Modeling of Vibrations
(Master thesis, 2018)The purpose of this project is to investigate the application of multivariate analysis methods on vibration data obtained from a diesel engine using acoustic contact microphones. A fully instrumented Mercedes-Benz OM613 ... -
Condition monitoring of spar‐type floating wind turbine drivetrain using statistical fault diagnosis
(Journal article, 2018)Operation and maintenance costs are significant for large‐scale wind turbines and particularly so for offshore. A well‐organized operation and maintenance strategy is vital to ensure the reliability, availability, and ... -
Condition Monitoring: Based on "black-box"- and First Principal Models
(Master thesis, 2011)Summary and conclusionsThis master thesis investigates Principal Component Analysis (PCA) methods used in the field of Early Fault and Disturbance Detection (EFDD). Statoil and ABB have in collaboration developed an ... -
Conditions for maximum energy transfer in inductive road-powered electric vehicle applications taking system limitations into account
(Chapter, 2021)This paper deals with the problem of maximizing the energy transfer between infrastructure for inductive power transfer embedded in the road and a moving electric vehicle. The analysis is assuming a series-series compensated ... -
