A two-step algorithm to solve the broadcast scheduling problem is presented. The first step employs finding a solution that has a transmission time slot for each station, while the second step attempts to maximise the throughput. Numerical examples that demonstrate the algorithm outperforms existing ones in terms of channel utilisation and packet delay are(More)
Despite the substantial research efforts on network coding, its real-world implementation is mainly over wireless networks or peer-to-peer networks. The deployment of network coding in the Internet core still largely lags behind. Among the many challenges, one difficulty is the selection of routers to perform network coding, which relies on the(More)
In this paper, we propose a novel method for low-resolution face recognition. It is especially useful for a common situation in forensic search where faces of low resolution, e.g. on surveillance footage or in a crowd, must be compared to a high-resolution reference. This method is based on the likelihood ratio of a pair of mixed-resolution input images.(More)
:Complex networks provide us a new view for investigation of complex systems. In this paper we collect data through STRING database and present an cytokine-protein network model with cooperation network theory. The results show that this model could describe the cytokine-protein collaboration preferably.The basic attributes of this network is well(More)
