＜正＞ We present a novel quantization-based digital audio watermarking scheme in wavelet domain. By quantizing a host audio’ s wavelet coefficients （Integer Lifting Wavelet Transform ） and utilizing the characteristics of human auditory system （HAS）, the gray image is embedded using our watermarking method. Experimental results show that the proposed watermarking scheme is inaudible and robust against various signal processing such as noising adding, lossy compression, low pass filtering, re-sampling, and re-quantifying.

铁路行业推行安全风险管理工作取得了初步成效,部分铁路局也分别建设了适合自身的风险管理系统,但目前铁路安全风险管理中还存在缺乏统一信息平台、风险管理信息不完整、安全风险控制方法不够完善等问题。为此,在分析系统需求的基础上,以建立适合中国铁路总公司和铁路局2级应用的统一铁路安全风险预警系统为目标,确定系统整体逻辑架构,对核心业务进行细化的功能设计,同时研究并应用系统实现所涉及的关键技术,包括用工作流技术实现风险监测信息采集和闭环流转,基于Web服务解决总公司和铁路局2级服务器之间的数据传输,利用风险矩阵法对安全风险进行评价等。目前风险预警系统已初步实现了对铁路风险因素和风险事故的有效管理。

A group of features is defined to describe the synthetic performance of processing cells and distinguish their heterogeneousness in large-scale heterogeneous computing environments. Three notable features that can effectively partition the processing cells of target system with fuzzy clustering are verified through several groups of experiments. Based on fuzzy clustering results of the target system, a Scheduling heuristic algorithm is presented. In the scheduling stage, the cluster with better synthetic performance will be chose first. The algorithm greatly reduces the time spent on the processor selection for large-scale system. The priority designation of tasks takes the influence of critical path nodes and heterogeneous resource into consideration. Experimental results show that it performs very well compared with other algorithm.
