ESTIMATION OF SATELLITE-BASED SO42− AND NH4+ COMPOSITION OF AMBIENT FINE PARTICULATE MATTER OVER CHINA USING CHEMICAL TRANSPORT MODEL
PM2.5 chemical components sulfate ammonium satellite-estimated chemical transport model
2018/5/15
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 ...
POSITION ESTIMATION OF AERIAL VEHICLE BASED ON A VISION AIDED NAVIGATION SYSTEM
Navigation Pose Estimation Geo-Referencing Vision-Based Matching Fuzzy reasonning
2015/9/28
Automatic pose estimation remains to be one of the challenging problems in photogrammetry and computer vision. When other
systems (e.g. GPS and INS) are inadequate, and real time precise positioning...
