Variable speed drives (VSDs) cause motor overvoltage stresses to result from fast-front voltage waveforms emerging from the converter, in particular when filters are not installed at the converter output terminals. This work investigates modeling procedures for predicting the overvoltages on a...
Risk models may provide information about the risk associated with the operation of technical systems, and their output may be used as input to decision-making, e.g., by human operators. For highly autonomous systems, it is desirable to use risk models to enable the system itself to make risk-aware...
Underwater navigation is an area of increasing research interest due to its fundamental complexity and industrial applications. However, due to convenience and current theoretical understanding, the vast majority of underwater platforms utilize thrusters, while other forms of propulsion, such as...
Prosjektet "Barnas luftkvalitet: En studie om innendørs luftkvalitet i barnehager og astma og allergi", finansiert av Forskningsfondet for astma og allergi, gjennomførte en spørreundersøkelse blant norske barnehager sommeren 2024. Målet var å undersøke forhold ved barnehagene som kan påvirke...
Denne rapporten oppsummerer resultater fra FHF-prosjektet «Alvorlige ulykker i kystfiskeflåten – årsaker og tiltak». Prosjektet har bidratt med oppdatert kunnskap om årsaker til ulykker og sikkerhetsutfordringer i arbeidsmiljøet og forslag tiltak for å redusere risikoen for personskader. Det er...
Cloud computing is increasingly being used not only to support critical infrastructure applications, but actually forms a vital part of them. This paper discusses challenges faced by custodians of critical infrastructures when moving to the cloud, and outlines some security requirements that are...
Due to the need to strictly control the measurements, tire manufacturers strive to conduct most of the tests indoors. This allows them to perform them regardless of weather conditions, all the yearlong. Currently, a lot of research concerns the rolling resistance of tires. These include both...
