Reliable estimation of reference evapotranspiration (ET0) is essential for irrigation scheduling and agricultural water-resources management. Although the FAO-56 Penman–Monteith equation is widely accepted as the stand...

Abstract This study characterizes the seasonal variations and cross-boundary aerosol transport in central Thailand using a combination of low-cost PM2.5 sensors, sunphotometer observations, and Himawari-9 satellite aeros...

Thermoelectric generators offer a promising solution for sustainable, low-maintenance energy harvesting in smart agriculture, especially for powering off-grid sensor nodes and microgrid systems. However, their inherently...

Abstract Seafloor networks detect earthquakes and tsunamis more quickly than those on the mainland in the subduction zones. N-net was constructed in the western portion of the Nankai Trough subduction zone to fill the ga...

High-voltage cable systems are critical components of power transmission networks, where partial discharge (PD) can cause insulation degradation and severe operational failures. Accurate detection and reliable identifica...

Abstract Seismic surveying has continuously evolved, transitioning from early mechanical seismoscopes to digital, multi-channel geophone arrays that defined the industry standard since 1970s. digital seismic reflection. ...
