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...
Accelerated aging tests have been performed to determine the influence of coastal climate (salt mist) on connectors for use to transfer power from shore to vessel batteries. The test objects were CCS Combo 2 (DC) and Type 2 (AC). The tests simulate about three and a half years of operation in...
På Norsk bygningsfysikkdag 25. november får du høre om utfordringer og løsninger for tak og fasader, og mange andre aktuelle anbefalinger....
Digital twins have a wide range of applications, and the interest in digital twins from academia and industry has increased substantially in recent years, which has been confirmed by annual market growth and the number of publications per year. The initially loose interpretation of the term digital...
Hydrogen has been seen as a possible energy carrier in the transition toward carbon neutrality. To make large-scale hydrogen use feasible, an extensive distribution network is needed. Pipelines are the most efficient way to transport hydrogen over long distances, and reusing existing natural gas...
