1A Dependability Model for TMR System显示文摘Much research has been done on the dependability evaluation of computer systems. However, much of this is gone no further than study of the fault coverage of such systems, with little focus on the relationship between fault coverage and overall system dependability. In this paper, a Markovian dependability model for triple-modular-redundancy (TMR) system is presented. Having fully considered the effects of fault coverage, working time, and constant failure rate of single module on the dependability of the target TMR system, the model is built based on the stepwise degradation strategy. Through the model, the relationship between the fault coverage and the dependability of the system is determined. What is more, the dependability of the system can be dynamically and precisely predicted at any given time with the fault coverage set. This will be of much benefit for the dependability evaluation and improvement, and be helpful for the system design and maintenance.Peng, Jun-Jie Liu, Yan-Ping Chen, Yuan-Yuan 2012International Journal of Automation and computing2012,9,3:1
2基于特征聚合的管制语音声纹深度识别方法显示文摘针对带有噪声的管制语音声纹识别问题,提出了一种基于特征聚合的声纹识别算法,能够在音频流中识别不同的管制员和飞行员的声纹特征。在经典的X-VECTORS算法的基础上,通过设计残差语谱图特征提取模块和全局可微的NetVLAD特征聚合模块,构造了端到端的说话人识别神经网络训练框架;最后在实际管制语音数据集上对各种说话人识别方法的精度进行了对比分析。实验结果表明,相较于传统的X-VETCORS方法,提出的基于声纹聚合的说话人识别方法具有更高的识别精度。李印轩 汤闻易 杨涛 王雪川 李呈祥 2023指挥控制与仿真2023,45,2:0
3Estimation of Reliability and Cost Relationship for Architecture-based Software显示文摘In this paper,we propose a new method to estimate the relationship between software reliability and software development cost taking into account the complexity for developing the software system and the size of software intended to develop during the implementation phase of the software development life cycle.On the basis of estimated relationship,a set of empirical data has been used to validate the correctness of the proposed model by comparing the result with the other existing models.The outcome of this work shows that the method proposed here is a relatively straightforward one in formulating the relationship between reliability and cost during implementation phase.Hui Guan Wei-Ru Chen Ning Huang Hong-Ji Yang 2010International Journal of Automation and computing2010,7,4:0
