In this paper, we described a positioning system based on radio frequency identification (RFID) which is suitable for nursing home. Received Signal Strength Indication (RSSI) positioning technology is used to realize indoor location, Global Positioning System (GPS) technology and General Packet Radio Service (GPRS) communication technology are adopted as a supplement for outdoor location. This system...
GPS-enabled devices have greatly facilitated the continuous collection of highly accurate locational data for moving objects including humans. The effective and efficient detection of mobility mode from raw GPS data is critically important for social behavior and public health research. In this paper, we propose a new method that can be used to automate the detection of human mobility mode by synthetically...
The great Wenchuan earthquake of M8.0 on May 12, 2008, occurred in an area with dense GPS observation stations in the regional network of the Crustal Movement Observation Network of China (CMONOC). Non-continuous observations were carried out at the 1 000 GPS stations of the regional network in 1999, 2001, 2004 and 2007. The horizontal displacements at GPS stations in the regional network before the...
