Investigation of the vault curve of East-China type multi-span greenhouse
Published 2005-07-01“…Meanwhile, taking the mutual shading effect of the neighboring spans into account, the direct solar radiation of arc vault of both east-west and south-north oriented multi-span greenhouse at noon on the day of winter solstice was calculated using the curvilinear integral method. Our result showed that greenhouse would have maximum snow-load bearing capacity when its vault tangential angle was in the range of 15°-20°, whereas the solar radiation collection ability of greenhouse was not significantly affected by variation in tangential angle of the vault.…”

Relating wildfire seasonality to remotely sensed fuel phenology: a tool for a new pyrogeography?
Published 2023-04-01“… In the Mediterranean region, notwithstanding the high human pressure, fire activity is essentially drought-driven, such that fuel moisture represents the main determinant for sustaining fire ignition and spread. Seasonal variations in remotely sensed vegetation indices, such as the Normalized Difference Vegetation Index (NDVI), proved to be indicative of variations in fuel amount and moisture content and associated fire risk. …”
