Triboelectrostatic beneficiation is an effective technique to remove unburned carbon from fly ash. The purpose of this study is to enhance the particles tribocharging, and improve the efficiency of removal unburned carbon from fly ash using electrical heating. An experimental system with electrical heating was established to realize the tribocharging measurement and fly ash triboelectrostatic beneficiation...
Pedestrian dead reckoning (PDR) systems which based on inertial sensors to capture user's movement, and wireless positioning systems which adopt wireless local area network (WLAN) for indoor pedestrian localization have been widely studied in recent years. Inertial navigation system is self-contained and reliable in a short period of time with errors accumulated over time. Wireless positioning has...
High precision gyroscopes are often used to find the north direction or determine the orientation by detecting the horizontal component of the earth's rotation rate in the field of north-seeking, oil drilling and mining. The ability to measure the earth's rotation rate accurately for gyroscopes can be applied as a basic criterion in those areas. MEMS gyroscopes were thought unable to measure the earth's...
Foot-mounted inertial navigation system (INS) composed of MEMS-based inertial sensors is widely used in pedestrian navigation. The bias of gyro and accelerometer are the most important parameter which mainly determines the performance and the price of the device. How does the bias impact the performance of foot-mounted INS? How do we choose the suitable inertial sensors in the design of foot-mounted...
