This paper presents a path-based fault-injection approach to increase the eeciency of computer system dependability evaluation. Our approach utilizes knowledge about the execution path to ensure that injected faults are activated. The control ow associated with each path is analyzed to determine the faults that would be activated by that path. By selecting a set of paths that covers a signiican...

a doublet of earthquakes with magnitudes of 6.5 and 6.2 in mw scale (global cmt) on 2010 december 20 and 2011 january 27 respectively struck the area that lies between the nehbandan and jiroft fault systems, southeast of iran. these earthquakes occurred in correspondence of the southwestern termination of the kahourak right lateral strike slip fault. the focal mechanisms of both the mainshocks ...

Fault diagnosis of analog circuits is essential for analog and mixed-signal systems testing and maintenance. A new method is proposed in this paper for multiple fault diagnosis of linear analog circuits in frequency domain. Woodbury formula is applied to the modified nodal equation to construct the fault diagnosis equation, which relates the limited measured circuit responses with the multiple ...

ÐThis paper presents a class of count-and-threshold mechanisms, collectively named -count, which are able to discriminate between transient faults and intermittent faults in computing systems. For many years, commercial systems have been using transient fault discrimination via threshold-based techniques. We aim to contribute to the utility of count-and-threshold schemes, by exploring their eff...

This paper presents an approach for data-driven design of fault diagnosis system. The proposed fault diagnosis scheme consists of an adaptive residual generator and a bank of isolation observers, whose parameters are directly identified from the process data without identification of complete process model. To deal with normal variations in the process, the parameters of residual generator are ...

In the case of condition diagnosis of the plant machinery, particularly rotating machinery, the utilization of vibration signals is effective in the detection of faults and the discrimination of fault type, because the signals carry dynamic information about the machine state. Condition diagnosis depends largely on the feature analysis of vibration signals, so it is important that the feature o...

In this paper, some recent advancement made in the field of model based fault identification are elucidated and shown that bond graph modeling is well suited to solve fault detection and isolation problems in automated real time process engineering supervision systems. We present a case study and implement an online fault diagnosis scheme through parameter estimation to a belt conveyor system. ...

A silicon independent C-Based model of the TTP/C protocol was implemented within the EU-founded project FIT. The C-based model is integrated in the C-Sim simulation environment. The main objective of this work is to verify whether the simulation model of the TTP/C protocol behaves in the presence of faults in the same way as the existing hardware prototype implementation. Thus, the experimental...
