Axis orbit is very important in fault monitoring and diagnosis of rotary machines. However, characteristics of axis orbit have lots of varieties. To support information fusion of characteristics, this paper elaborates the analysis and comparison of 22 characteristics of axis orbit for the on-line fault pattern recognition. The stability, sensibility and validity of different characteristics are analyzed...
Monitoring and fault tolerance are important approaches to give high confidence that long-running online software systems run correctly. But these approaches will certainly cause high overhead cost, i.e. the loss of efficiency. Multi-core platforms can make such cost acceptable because of the advantage of the parallel performance. For allowing ordinary software developers without any knowledge of...
Aircraft Engine Health Management (EHM) System deals with the monitoring, detection, isolation, trend prediction and accommodation of engine degradation, faults, and failures. Minimizing total cost of engine ownership, increasing asset availability/mission readiness and while maintaining or even increasing safety are the key drivers for the implementation of EHM System. This paper investigates the...
A collaborative monitoring system Based on JXTA is designed here. The architecture and specific implementation are proposed. The paper emphasizes on introducing the method of monitoring the network by collaborative peers applying P2P technology and the implementation procedure of monitoring the CISCO3640 port utility. The system features on expansibility, usability and interoperability, high performance,...
