Advanced ship predictors can generally be considered as a vital part of the decision-making process of autonomous ships in the future, where the information on vessel maneuvering behavior can be used as the source of information to estimate current vessel motions and predict future behavior...
In this paper, we evaluate the reasoning performance of six prominent OWL 2 DL reasoners, using two collections of ontologies: ORE 2015 and the 21 largest ontologies from the NCBO BioPortal. We observed that the majority of the reasoners were unable to successfully perform over half of the reasoning...
This work presents a data-centric approach to the implementation of tabletop projection mapping, utilising the technology for data visualisation purposes with a focus on real-time geospatial data. The goal of the implementation is for multiple users or viewers to acquire a four-dimensional augmented...
Chilling is an essential preservation technology in fish-processing. Slurry systems offer seafood preservation at sub-zero temperatures with advantages like faster chilling, reduced physical damage and prolonged shelf life. The study was conducted on wild caught cod (Gadus morhua) and haddock...
Probabilistic operational planning of power systems usually requires computationally intensive and time consuming simulations. The method presented in this paper provides a time efficient alternative to predict the socio-economic cost of system operational strategies using graph convolutional...
Forringelse av gulrøtter på grunn av tuppråte medfører kvalitetstap og matsvinn. Også innen produksjon av moreller sliter man med flere soppsykdommer som kan gi store produksjonstap. I et nytt forprosjekt skal SINTEF og NORSØK se på om det er mulig å hindre disse sykdommene ved å behandle produktene...
Home Software Technologies Conference paper Adapting Cyber-Risk Assessment for the Planning of Cyber-Physical Smart Grids Based on Industrial Needs Gencer Erdogan, Iver Bakken Sperstad, Michele Garau, Oddbjørn Gjerde, Inger Anne Tøndel, Shukun Tokas & Martin Gilje Jaatun Conference paper...
This paper proposes a low-cost solution for localizing a remotely operated vehicle (ROV) inside a fish net pen. The solution consists of a kinematic Kalman Filter capable of estimating the absolute ROV position and orientation in a fish net pen using primarily the onboard compass, laser-camera...
Tradisjonelle desinfeksjonsmetoder for ferske frukt og grønnsaker har sine begrensninger. Ozonbehandling er imidlertid et lovende alternativ for å forlenge holdbarheten og øke mattryggheten. Denne artikkelen utforsker bruk av ozon for å bekjempe mikroorganismer, forbedre ernæringsmessig kvalitet og...
An overview of integrated technologies based on heat pumps, thermal energy storage and smart control systems is provided. Heat pumps are devices that transfer thermal energy from low-temperature to high-temperature areas, consuming a small amount of electricity in the process. Their working...
With the Yara Birkeland, the world’s first autonomous cargo ship developed for commercial use, nearing regular unmanned operation, it is crucial to assess the availability and readiness of unmanned cargo handling solutions. While there are already fully automated container terminals at large...
We discuss a nonlinear domain-decomposition preconditioning method for fully implicit simulations of multicomponent porous media flow based on the additive Schwarz preconditioned exact Newton method (ASPEN). The method efficiently accelerates nonlinear convergence by resolving unbalanced...
The electricity market is driven by complicated interactions that are hard to model analytically. This is particularly the case for the balancing market, where imbalances between supply and demand after the day-ahead market clearance are balanced. The balancing market bridges the gap between the day...
We demonstrate a newly developed high-performance fixed-bed reactor combined with an in situ mass analyzer (ISMA). The ISMA is particularly relevant to sub-second time-resolved studies where mass changes occur due to, e.g., chemical reactions and process conditions such as choice of solid...
Dette er den faglige sluttrapporten for prosjektet "STARTRENS – Optimalisert startfôring av rensefisk" som ble finansiert av Fiskeri- og havbruksnæringens forskningsfinansiering (#901561). Rensefisk har en sentral rolle i laksenæringen som ikke-medikamentell behandling mot lakselus, og behovet for...
