An attempt has been made to predict the ice rubble field load on Norströmsgrund lighthouse by using Cohesive Element (CE) formulation. Two sub-load events were selected to validate the numerical and material model used in simulation of interaction of the ice rubble field and lighthouse. A literature...

Since 2017, observations of ice conditions have been made in the northern Norwegian fjord, Beisfjord, to better understand the mechanisms of ice formation and variability in ice thickness, crystallography, and properties including salinity and δ 18 O. Data from Fall 2017 to Spring 202 0 have...

The construction industry has a significant impact in terms of financial and environmental resources but is vastly behind other sectors in terms of digitalization. The potential of this industry to be improved by new technology has been reflected in huge trends in research for terms such as...

The snow galleries along the Iron Ore railway line in Northern Sweden have faced problems in recent years due to increasingly large snow loads, and several galleries have been damaged. These incidents motivated an evaluation of the maximum load supported by the galleries before collapse, which is...

Static ice loads are a significant aspect of the design of hydropower dams in Norway due to their low height. Results are presented from a preliminary study to investigate whether elastic foam could be used to reduce static ice loads. Frames with stress cells were mounted on the dam at...

When assessing the sliding stability of a concrete dam, the influence of large-scale asperities in the sliding plane is often ignored due to limitations of the analytical rigid body assessment methods provided by current dam assessment guidelines. However, these asperities can potentially improve...

The launch of MF Estelle, the world’s first commercial autonomous passenger ferry, in Stockholm in 2023 has accelerated the need to establish a Remote Operation Centre (ROC) to manage multiple vessels with fewer human supervisors, reducing operational costs. This transition, by technological...

Abstract Background Boars undergo physiological and biochemical changes in semen composition as they grow from puberty to sexual maturity. However, comprehensive metabolomic profiles of boar semen remain uncharacterised. Understanding metabolic alterations in semen during this period is important...

As researchers unravel the underlying mechanisms governing time-dependent electrical degradation[1], thin film piezoelectric microelectromechanical systems (piezoMEMS) display electrical lifetimes satisfactory for a wide range of technological applications. Even in the harsh ambient of space[2]. As...

Kommunene sliter med å få tak i ingeniører og teknologer. Nå advarer Tekna om at vannforsyning og beredskap er i fare....

Er du opptatt av å redusere risikoen for vannskader i bygg? Da bør du ikke gå glipp av Norsk vannskadedag 2025 – nå for første gang som webinar....

Cervical cancer screening is an effective way of detecting and preventing precancer from further developing. Especially when it´s done in the recommended frequency. However, the constant evolving screening guidelines make it difficult for both the doctors and screening participants to interpret test...

Prosjektet GEOSFAIR har utviklet metoder for å innlemme droner med sensorer i Statens vegvesen sitt system for beslutning om snøskredfare. Teknologien er testet under realistiske feltforhold, programvare og arbeidsmetodikk er utviklet. Det er gitt anbefalinger om bruk av kamera (for fotogrammetri...
