Epidemiologic and health impact studies have examined the chemical composition of ambient PM2.5 in China but have been constrained by the paucity of long-term ground measurements. Using the GEOS-Chem ...
In SAR image interpretation, aircrafts are the important targets arousing much attention. However, it is far from easy to segment an aircraft from the background completely and precisely in SAR images...
The ionosphere spatial gradient and its temporal rate of change in the vicinity of a LAAS-equipped airport are likely to influence the architecture required to meet the Category II/III precision appro...
Several recent papers have analyzed the potential threat of severe ionosphere spatial gradients on LAAS users [1-4]. To support this work, a comprehensive methodology has been developed to analyze WAA...
Single-frequency based Satellite-Based Augmentation Systems (SBAS), the augmentation of the Global Navigation Satellite System (GNSS), broadcast estimates of vertical ionospheric delays and confidence...
To support food security, information products about the actual cropping area per crop type, the current status of agricultural production and estimated yields, as well as the sustainability of the ...
The optimization method of a mathematical model and connected-pipe experimental technique for a test in altitude test facility (ATF) of a liquid fuel ramjet engine was researched.The optimization of t...
