in this study, the 2005 dahuieh (zarand) locally recorded aftershock sequence has been analyzed. having the distribution of aftershocks and the source extension, a w-e trending near vertical faulting with an extension of about 15-20 km could be estimated. the rupture causing the powerful dahuieh earthquake apparently initiated in the modified epicentric area and propagated unilaterally towards ...

This paper proposes a holistic teleology-based modeling framework for product-related processes named FOREST. Several processes such as functioning processes, fault-related processes and manufacturing processes can be represented as goal-oriented process trees in the three-dimensional space as an extension of an ontology-based functional modeling framework. One of the expected benefits is to he...

The paper introduces the concept of fault diagnosis using an observer bank of autoregressive time series models. The concept was applied experimentally to diagnose a number of induced faults in a rolling element bearing using the measured time series vibration signal. Three distinct techniques of autoregressive modeling were compared for their performance and reliability under conditions of var...

In today's competitive IC market, success often means delivering the shortest possible clock cycle. Under pressure to push increasingly complex processing technologies to the limits, designers are delivering circuits with decreased timing and noise margins. In doing so, they are making the circuits significantly more susceptible to manufacturing imperfections. In particular, previously benign m...

Incipient fault diagnosis of chemical processes via artiicial neural networks. 23 investigate the eeect of modeling uncertainties on the performance of the FDA system. of faults in a multi-loop launch vehicle guidance and control system. Fault diagnosis in dynamic systems using analytical and knowledge-based redundancy | a survey and some new results.

A two-port memory contains two duplicated sets of address decoders which operate independently. In this paper the effects of interference and shorts between the address decoders of the two ports on the fault modeling are investigated. Fault models and their tests are introduced, together with the test strategy.

Abstract—Testability modeling is a commonly used method in testability design and analysis of system. A dependency matrix will be obtained from testability modeling, and we will give a quantitative evaluation about fault detection and isolation. Based on the dependency matrix, we can obtain the diagnosis tree. The tree provides the procedures of the fault detection and isolation. But the depend...

Fault localization is a process of isolating faults responsible for the observable malfunctioning of the managed system. Until recently, fault localization efforts concentrated mostly on diagnosing faults related to the availability of network resources in the lowest layers of the protocol stack. This paper focuses on end-toend service failure diagnosis as a critical step towards multi-layer fa...

Workflow technology is an emerging paradigm for systematic modeling and orchestration of job flow for enterprise and scientific applications. This paper introduces BPEL4Job, a BPEL-based design for fault handling of job flow in a distributed computing environment. The features of the proposed design include: a two-stage approach for job flow modeling that separates base flow structure from faul...

Modeling the reliability of distributed systems requires a good understanding of the reliability of the components. Careful modeling allows highly fault-tolerant distributed applications to be constructed at the least cost. Realistic estimates can be found by measuring the performance of actual systems. An enormous amount of information about system performance can be acquired with no special p...
