considering recent developments in earthquake engineering, researchers has detected different effects of earthquakes far and near from the fault. investigations that have been done in this area show that near fault earthquakes have shorter time period comparing far fault earthquakes and in the velocity of near fault earthquakes, there are one or more impacting pulses with a big domain and perio...

Web-based engineering design activities require fault tolerance and concurrent access to shared resources such as databases and Web servers. Such activities are generally dynamic, cooperative, long-lived, interactive, and non-prescriptive. We propose a new multi-agent transaction model, which is based on extended transactions and multi-agent technologies. The novelty of this model is that it au...

This paper deals with different software based strategies allowing the on-line detection of bit flip errors arising in microprocessor-based digital architectures as the consequence of the interaction with radiation. Fault injection experiments put in evidence the detection capabilities and the limitations of each of the studied techniques. RELATED TOPICS: Radiation effects, fault tolerant syste...

This paper presents a novel idea of automatic fault localization by exploiting counterexamples generated by a model checker. The key insight is that, if a candidate statement is faulty, it is possible to modify (i.e. correct) this statement so that the counterexample is eliminated. We have implemented the proposed fault localization algorithm for component-based systems modelled in the BIP (Beh...

Real-time control applications involve the interaction of multiple components. As systems become more complex their reliability tends to decrease, hence, fault tolerance must be incorporated to keep reliability within specified levels. A reconfiguration mechanism for processor arrays inspired by mechanisms that take place during the embryonic development of living beings is proposed in this pap...

– An important problem in designing infrastructure to support business-to-business integration (B2Bi) is how to cancel a long-running interaction (either because the user has changed their mind, or in response to an unrecoverable failure). We review the fault-handling and compensation mechanism that is now used in most workflow products and business process modelling standards. We then use an e...

The development of on line model-based fault detection systems in machinery improves the operational reliability of industrial systems and reduces the operational and maintenance costs. In this direction, this paper presents the use of modelling information to determine changes in characteristics from measured data for the fault detection purpose of hydraulic driven machines as well as for the ...

It is not possible to do automatic testing with step motors in Hardware-in-the-Loop (HIL) simulators because motors may be overheated if working for a long time. Furthermore, possibilities for fault injection are limited and physical interaction is needed to inject faults like a breakdown that can actually be mimicked. We present an emulator in an FPGA that allows to emulate a step motor for au...

Bi-directional request-response interaction is a standard communication pattern in Service Oriented Computing (SOC). Such a pattern should be interrupted in case of faults. In the literature, different approaches have been considered: WS-BPEL discards the response, while Jolie waits for it in order to allow the fault handler to appropriately close the conversation with the remote service. We in...
