A latency-hiding algorithm for the parallelization of large scale agent-based model simulations (ABMS) on parallel/distributed computing platform is proposed. The key idea of this algorithm is using redundant computations to hide communication latencies. An analytical model for this algorithm is presented to tell how to select R value to reach the best speedup. Compared to B+2R algorithm [1], theoretical...
The meaning of sound quality assessment is summarized. Based on the analysis of some characteristics of human auditory system and the model of loudness perception, an efficient loudness estimation approximate algorithm is proposed using the regression analysis method. Experimental results show that the approximate algorithm has fine performance for speech signal. Additionally, different people's speech...
In the field of data mining, clustering is one of the important methods. K-Means is a typical distance-based clustering algorithm; 2-tier clustering should implement scalable clustering by means of dividing, sampling and knowledge integrating. Among those tools of distributed processing, Map-Reduce has been widely embraced by both academia and industry. Hadoop is an open-source parallel and distributed...
Designated verifier signature (DVS) does not provide non-repudiation property of traditional digital signatures. Multi-signers strong designated verifier signature (MS-SDVS) scheme is required in some cases for the privacy consideration. In this paper the definition and security model of MS-SDVS scheme are presented, and a concrete MS-SDVS scheme is proposed from bilinear pairing. The proposed scheme...
