An energy-efficient association control algorithm for wireless networks is proposed. Both the wake-sleep switch of each base station and the resource reservation overhead of its neighboring base stations are considered as factors to impact the base station on-off switch decision and the user association. The simulation results show that the overall system energy consumption can be reduced thanks to...
In this paper, we address the preparation of ecological datasets for data mining. We propose a new adaptive method for automatic dataset construction using Erblet transform, which can be seen as a non-uniform filter bank where the center frequency and the bandwidth of each filter match the ERB (Equivalent Rectangular Bandwidth) scale, followed by data quality assessment using a tonality index (TI)...
In this paper, we have examined the volatility spillovers between the CSI 300 index futures and its underlying spot market, using a bivariate BEKK GARCH model for a sample period of April 16, 2010 to January 18, 2013. This paper provides a unique perspective to incorporate the information of trading and non trading periods into the issue, yielding findings as follows. Firstly, most of the findings...
