A fault is (strongly) detectable if it is possible to construct a residual generator that is sensitive to the (constant) fault while decoupling all disturbances. Two new fault detectability criterions and three new strong fault detectability criterions are presented. For comparison, existing fault detectability criterions are reviewed. To prove the criterions, a framework of polynomial bases is...

The AI model-based diagnosis community has developed qualitative reasoning mechanisms for fault isolation in dynamic systems. Their emphasis has been on the fault isolation algorithms, and little attention has been paid to robust online detection and symbol generation that are essential components of a complete diagnostic solution. This paper discusses a robust diagnosis methodology for hybrid ...

Quality control in liquid transfer operations can eliminate false assay results due to transfer failures, monitor the stability of laboratory equipment, provide baselines for continuous improvement, and enable automatic recovery actions for a number of fault conditions. This paper describes the work done to add real-time quality control capability in liquid transfer operations on a closed-loop ...

This paper proposes a novel fault-tolerant disk subsystem named Zoned-RAID (Z-RAID). Z-RAID improves the performance of traditional RAID system by utilizing the zoning property of modern disks which provides multiple zones with different data transfer rates in a disk. This study proposes to optimize data transfer rate of RAID system by constraining placement of data blocks in multi-zone disks. ...

We simulated dynamic rupture propagation along a branched fault, which is partially segmented by a slit. This is an analogy of a strike slip fault, which displays a jog structure on the ground surface but forms a continuous system at depth. We observed that rupture directivity can significantly change due to the existence of the fault slit and that the relative location of the slit to the hypoc...
