Location fingerprinting for outdoor areas using existing wireless local area network infrastructure is growing rapidly in importance and gains commercial interests in location-based services. The most challenge in outdoor fingerprint positioning is the fluctuation of received signal strength (RSS). In the paper, we propose a micro-cell-based radio map construction method targeted to deal with the...
Reliable and real-time location information is important for location-based services (LBS) of the mobile terminals. Existing location techniques have poor performance in urban environments due to severe multipath and NLOS propagation. Fingerprint localization based on wireless-LAN (WLAN) has been preferred for those types of environments. However, the most challenge in fingerprint positioning is the...
This paper provides new test data of cyclic behavior of repaired concrete-filled steel tubular (CFST) columns after exposure to fire, the fire-damaged CFST columns being strengthened by wrapping the original columns by concrete and a thin-walled steel tube. The test parameters included the cross-section type (circular, square and rectangular), and the axial load level (0, 0.3, 0.6). It was found that...
