High Voltage, EarlyView.ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...

A sailwing vertical axis wind turbine for small scale applications [PDF]
The use of sailwing aerofoils in vertical axis wind turbines has been investigated. It was anticipated that this could make vertical axis turbines more suitable for water pumping and that this might help to meet the need for a cheap pump for ...

Animal Conservation, EarlyView.During their spawning migration, European silver eels frequently encounter hydropower facilities where successful downstream passage is essential for the conservation of this critically endangered species. In this study, we evaluated how three angled rack designs and individual behavioral variation influenced downstream passage success in large‐scale ...

Tubes or Ribbons? Comparing Texture‐space Visualization for Multivariate Line Data
Computer Graphics Forum, EarlyView.Abstract Multivariate line data is critical for analyzing flow fields, agent systems, and dynamic trajectories. Embedding secondary variables along spatial paths using surface‐based primitives such as ribbons and circular tubes introduces challenges related to perspective, scale, and distortion.

European Journal of Dental Education, EarlyView.ABSTRACT Introduction Dental education involves continuous exposure to high‐frequency noise from clinical instruments, which may cause early outer hair cell damage even before professional practice begins. While noise‐induced hearing loss (NIHL) is a recognised occupational hazard among dentists, evidence regarding subclinical outer hair cell changes ...
