The Potential of ICESat-2 to Identify Carbon-Rich Peatlands in Indonesia
Peatlands in Indonesia are one of the primary global storages for terrestrial organic carbon. Poor land management, drainage, and recurrent fires lead to the release of huge amounts of carbon dioxide.

RSS-Ratio for enhancing performance of RSS-based applications [PDF]
RSS (Received Signal Strength) has been widely utilized in wireless applications. It is, however, susceptible to environmental unknowns from both temporal and spatial domains. As a result, the fluctuation of RSS may degrade performance of RSS based applications.
