State evaluation is vital to ensure the process operating optimality for copper flotation processes. Specifically, the froth image is the comprehensive embodiment of raw ore properties and process operations, which is one of the key factors to realize condition recognition and state evaluation. Firstly, a feature mosaic technique‐based neural network framework is proposed. The input image features...
Access security is the key obstacle of the rapid popularization of wireless mesh network (WMN). We suggest the proxy group signature scheme based on identity in this paper. This scheme is combined with proxy group signature and identity-based group signature, based on designated hierarchical proxy architecture for WMN. An anonymous mutual authentication scheme is thus achieved, which not only simplifies...
