How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Low-Voltage Ride-Through Algorithm for Grid-Forming Converters

open access: yesIEEE Transactions on Power Electronics
In recent years, the increasing integration of renewable energy sources into power systems has led to significant changes in grid operation. Power electronic converters are primarily used to connect these power plants to the electrical system and, as key components in modern power systems, grid-forming (GFM) converters have emerged to provide the ...

Barriers and Enablers of Circular Economy in Electrical and Electronic Equipment: A Systematic Literature Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Rapid technological change, shorter lifecycles and rising demand for electrical and electronic equipment (EEE) are increasing waste electrical and electronic equipment (WEEE) and emphasise the need for a circular economy. This paper identifies barriers and enablers of the circular transition in EEE and outlines interventions.
