Enhanced Strength–Ductility Synergy of Mg-Al-Sn-Ca Alloy via Composite Asymmetric Extrusion
CrystalsFine-grain and weak-texture magnesium alloys are the long-term development targets of lightweight structural materials. In this study, a new composite asymmetric extrusion (CAE) is developed, which, coupling with an asymmetric die and an asymmetric ...

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 ...

Pixel‐Level Inversion Assessment for Ageing of Composite Insulator Sheds of Power System
High Voltage, EarlyView.ABSTRACT The polymeric materials used in insulator sheds are prone to ageing under different environmental conditions, which can lead to flashovers and grid outages. The ageing process in composite insulators primarily involves changes in the microscopic properties of the materials.

Forces Behind South Australia's Unusual Structural Changes Since 1840
Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT The agricultural sector's share of GDP in growing economies typically declines but, for a century from the early 1850s, Australia's did not. That trend is most evident for the former colony and now State of South Australia (SA). Moreover, that share for SA has been almost flat since 1980 as well, along with the agricultural sector's share of ...

Review on Magnetic Field Analytical Methods for Permanent Magnet Machines
IEEE AccessThis paper systematically reviews magnetic field analytical methods, categorizing three conventional and three hybrid methods. The accurate modeling of regular shapes can be achieved by the Subdomain method (SD) but suffers from complex multi-layer ...
