A data-driven approach to improve control room operators' response
(Peer reviewed; Journal article, 2021) -
A data-driven method based on deep belief networks for backlash error prediction in machining centers
(Journal article; Peer reviewed, 2017)Backlash error occurs in a machining center may lead to a series of changes in the geometry of the components and subsequently deteriorate the overall performance of the equipment. Due to the uncertainty of mechanical wear ... -
A dataset of wind-driven rain measurements on a low-rise test building in Norway
(Journal article; Peer reviewed, 2007)Semi-empirical models and especially numerical simulation models based on Computational Fluid Dynamics (CFD) are increasingly being used to calculate wind-driven rain (WDR) on building facades. The development, verification ... -
A DBN-based risk assessment model for prediction and diagnosis of offshore drilling incidents
(Journal article; Peer reviewed, 2016)Drilling operations of offshore oil and gas fields are characterized by high technical complexity, high risks, and high costs, since they are always in harsh environments with complicated geological factors. Lost circulation ... -

A decentralized sensor fusion approach to human fatigue monitoring in maritime operations
(Chapter, 2019)Human fatigue is one of the main causes of accidents in maritime domain. How to use physiological data to estimate degree of human fatigue without medical domain knowledge is significant to the safety of tasks in maritime ... -
A decision support framework for holistic stormwater management planning
(Master thesis, 2022)Overvann er en økende utfordring i urbane områder som følge av klimaendringer og fortetting. Kombinasjonen av disse faktorene bidrar til at overvannsmengdene overskrider kapasiteten i tradisjonelle rørsystemer. Dette skaper ... -
A Decision Support Methodology for Strategic Planning Under Uncertainty in Maritime Transportation
(Master thesis, 2012)Measured in volume approximately 80 % of world trade is carried at sea and with just as many different actors the shipping industry acts close to a perfect market. The highly volatile nature of the industry with unexpected ... -
A Decision Support Model for Merchant Vessels Operating on the Arctic Sea
(Master thesis, 2012)With the ice cap diminishing rapidly on the Arctic Sea, the opportunity of using the Northern Sea Route (NSR) increases correspondingly. However, the climate and presence of ice on the NSR sets additional requirements, ... -
A deep learning approach for anomaly detection based on SAE and LSTM in mechanical equipment
(Journal article; Peer reviewed, 2019)Anomaly in mechanical systems may cause equipment to break down with serious safety, environment, and economic impact. Since many mechanical equipment usually operates under tough working environments, which makes them ... -
A Deep Learning Based Approach for Detecting Change of Buildings from Aerial Images
(Master thesis, 2022)Fremveksten i bruken av dyplæringsmetoder for bygning- og endringsdeteksjon har økt jevnt de siste ̊arene. Tilgjengeligheten og kvaliteten til høyoppløselige satellittbilder har tilrettelagt for en rekke muligheter innenfor ... -

A Degrading Element of Safety-instrumented Systems with Combined Maintenance Strategy
(Chapter, 2019)Safety-instrumented systems (SISs) are widely used to prevent hazardous events. The mechanical actuator subsystem in a SIS can become more vulnerable with time due to progressive degradation mechanisms, such as erosion, ... -
A density-dependent failure criterion for concrete
(Journal article, 2016)This work focuses on the large effect of small secondary stresses on the compressive strength of concrete. The strength and especially the ductility of structural concrete members depend on local triaxial stress conditions ... -
A depth semi-averaged model for coastal dynamics
(Journal article, 2017)The present work extends the semi-integrated method proposed by Antuono and Brocchini [“Beyond Boussinesq-type equations: Semi-integrated models for coastal dynamics,” Phys. Fluids 25(1), 016603 (2013)], which comprises a ... -
A design methodology for resilience in fleets for service operations
(Chapter, 2016)In this paper, we present a new conceptual design methodology for increasing the resilience in complex operations involving a fleet of ships. The objective of the methodology is to support design decisions to reduce ... -
A design methodology of a Product: Bicycle frame for simultaneous improvement of mechanical and environmental performance
(Master thesis, 2022)For tiden kan avanserte materialer kombinere høye mekaniske egenskaper med tilleggsegenskaper, for eksempel lettvekt, resirkulerbarhet eller andre funksjoner. I mange bransjer gir bruken av lette materialer som kompositter ... -
A Detached-Eddy-Simulation study: Proper-Orthogonal-Decomposition of the wake flow behind a model wind turbine
(Journal article; Peer reviewed, 2018)In times of intense renewable energy development, the planning of wind farms and the improvement of their total efficiency has become a major field of research. A precise analysis of the velocity deficit, fluctuation load ... -
A diagram for capturing and predicting failure locations in notch geometries produced by additive manufacturing
(Journal article; Peer reviewed, 2020)In a recent work by the authors Solberg and Berto (2019), as-built notch geometries of Inconel 718 produced by selective laser melting was investigated under fatigue loading. One of the findings was that fatigue did not ...
