Social voting is an emerging new feature in online social networks. It poses unique challenges and opportunities for recommendation. In this paper, we develop a set of matrix-factorization (MF) and nearest-neighbor (NN)-based recommender systems (RSs) that explore user social network and group affiliation information for social voting recommendation. Through experiments with real social voting traces,...
In order to identify the damage modes of 16 Mn steel, the tensile test of 16 Mn steel plate specimens was developed and monitored with acoustic emission technique. Based on the acoustic emission signature analysis during material damage, 3-layer back-propagation neural networks (BPNN) model with Tansig-Logsig transfer function was applied to identify the damage modes of 16 Mn steel in tensile test...
With the continuous progress of the society, requirement of the position control precision for the crane is becoming higher and higher. The running laws of the crane are analyzed and the electromechanical coupling model is established in this paper, thereby the state of the motor and the load's motion are unified effectively. Based on this model, the adaptive backstepping strategy is designed by regarding...
