A study on the classification of coastal wetland vegetation based on the Suaeda salsa index and its phenological characteristics
Published 2025-01-01“…Therefore, in this study, based on the analysis of the spectral separability of Suaeda salsa (S. salsa) and native vegetation, two new Red Suaeda salsa Indices (RSSI and RSSI(1)) were constructed by selecting the red, green and near-infrared bands of the Sentinel 2 multispectral band, and then, based on the sample points, we constructed the RSSI time series and fitted using Fourier function fitting, and extracted (a) Difference Of RSSI (DOR), (b) Sum Of RSSI (SOR), (c) Ratio Of Green-up RSSI (ROGR), and (d) Ratio Of Senescence RSSI (ROSR) from the phenological fitting curve. …”

Modeling “Wrong Side” Failures Caused by Geomagnetically Induced Currents in Electrified Railway Signaling Systems in the UK
Published 2023-12-01“…This study extends recent modeling of geomagnetic effects on DC signaling for AC‐electrified railways in the UK that analyzed “right side” failures in which green signals are turned to red. The extended model reported here allows the study of “wrong side” failures where red signals are turned green: a failure mode that is potentially more dangerous. …”
