Dynamic resource allocation for cognitive radio
Published 2012“…For the case of sequential channel sensing where an SU can sequentially sense the channels one at a time, the sensing-access design includes the sensing strategy determining when to stop sensing and start transmission, the access strategy specifying the transmit power level upon transmission, and the sensing order design telling the SU which channel to sense next if the current channel is given up for transmission. …”

Research on lithium ion battery applications in vehicles
Published 2014“…There are mainly four parts included in the intelligent battery cooling system, battery pack, temperature measurement circuit, DC-DC boost converter and a cooling device. When the temperature of battery pack rise to warning level, the output voltage of temperature measurement circuit will rise to a critical value under the amplification of boost converter, it can drive the cooling device (electric fan, etc.) and cool down the battery pack. …”

Development of localization algorithms for a WiFi based indoor positioning system with machine learning techniques
Published 2015“…Experimental results show that the DZ-ELM based IPS can not only provide higher accuracy, but also improve the repeatability of IPSs. Secondly, when assuming that noises lie in both input and output data, we exploit the fact that feature mapping in ELM is known to users to develop two kinds of robust ELM (RELM) based on second order cone programming. …”
