This study examines the impact of regional old-age dependency ratio on collection efficiency public pension funds using statistical data contributions schemes for urban employees in 31 Chinese provinces and municipalities between 2010 2015. An inverted U-curve relationship rate was observed with a single threshold value .5439, thus, suggesting need change soft constraints responsibility an opti...

Prognostics and Health Management (PHM) enabled maintenance is considered to be the most recent phase in the evolution of maintenance paradigms. It enables outcome-based contracts, dynamic warranties, maintenance-optimized availability, among other benefits. PHM enables flexibility whereby the decisionmaker can choose from a set of options arising after prognostic indication in order to manage ...

This paper presents a stability investigation of the step recessed, hydro-static and -dynamic hybrid water-lubricated journal bearings for fuel cell vehicle compressor. The dynamic coefficients and stability threshold speed of the bearings are numerically calculated by solving the turbulent Reynolds equation by using FEM. Two configuration bearings are comparatively studied and the different dy...

Due to abuse by insiders or penetration by outsiders, network systems usually suffer various security issues. In order to achieve high dependable and low cost monitoring, this paper proposes a dependable monitoring mechanism combining static threshold-based and dynamic anomaly detection. Firstly, the performance metrics of host and network are collected through different methods. In static thre...

The performance of cochlear implant patients may be related to intracochlear, histopathological factors. We have performed detailed post-mortem examinations of five human, implanted cochleas and for each electrode correlated the psychophysical threshold, comfortable level and dynamic range with spiral ganglion cell survival, presence of fibrous tissue and/or new bone, and distance between the c...

Buuer management schemes are needed in shared-memory ATM switches to regulate the sharing of memory among diierent output port queues and among traac classes with diierent loss priorities. Earlier we proposed a single-priority scheme called Dynamic Threshold, in which the maximum permissible queue length is proportional to the unused buuering in the switch. In this paper, we propose and analyze...
