A Review of Transient Support and Security‐Stability Enhancement Control Strategies for Grid‐Forming Voltage Source Converter‐Based High Voltage Direct Current Transmission

High Voltage, EarlyView.
ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.

The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

Methods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

Design Considerations for Visualization Transitions of 3D Spatial Data in Hybrid AR‐Desktop Environments

Computer Graphics Forum, EarlyView.
We present design considerations for animated transitions of the appearance of 3D spatial datasets in a hybrid Augmented Reality‐desktop context. Such hybrid interfaces combine both traditional and immersive displays to facilitate the exploration of 2D and 3D data representations in the environment in which they are best displayed.
