A new diagnostic fault simulator is described that diagnoses both feedback and nonfeedback bridge faults while using information from fault simulation of single stuck-at faults. A realistic fault model is used which considers the existence of the Byzantine Generals Problem. The approach has been demonstrated for two-line bridge faults on several large combinational benchmark circuits and has ac...

Alborz Mountains is a region of active deformation within Arabia-Eurasia collision zone. The study fault system in western Alborz comprises abundant evidence of active faulting accompanied by occurrence of historical earthquakes. Active tectonics of Manjil-Rudbar fault zone whose movement caused destructive 1990 Manjil-Rudbar earthquake was concentrated in this article through geomorphic and st...

In this paper we first show that standard BP algorithm cannot yeild to a uniform information distribution over the neural network architecture. A measure of sensitivity is defined to evaluate fault tolerance of neural network and then we show that the sensitivity of a link is closely related to the amount of information passes through it. Based on this assumption, we prove that the distribu...

Fractures of multi-scales and multi-origins are primary storage space effective seepage channels for metamorphic buried-hill reservoirs. They not only allow communication between various pores to enhance capacity, but also essential high yields. Fracture development controlling factors at reservoirs Bozhong 19-6 Gas Field were investigated based on imaging log, core data, experiments, e.g., thi...

In this paper we study the ability of array-based networks to tolerate worst-case faults. We show that an N N two-dimensional array can sustain N 1? worst-case faults, for any xed > 0, and still emulate a fully functioning N N array with only constant slowdown. Previously it was known only that an array could tolerate a constant number of faults with constant slowdown. We also show that if faul...

We investigate two strategies to guarantee temporal correctness of a combinational circuit. We rst propose a new technique to identify and test primitive faults. A primitive fault is a path delay fault that has to be tested to guarantee the performance of the circuit. Primitive faults can consist of single or multiple path delay faults. Testing strategies for single primitive faults exist. In t...

This paper presents a method for fault detection and diagnosis of actuator loss of effectiveness for a quadrotor helicopter. This paper not only considers the detection of the actuator loss of effectiveness faults, but also addresses the diagnosis of the faults. The detection and estimation of the faults are performed by the Augmented Extended Kalman Filter. The faults are modelled as random wa...

In testing sequential circuits, internal faults in the storage elements (SEs) are sometimes modeled as stuck-at faults in the combinational circuits surrounding the SE. The detection of some transistor-level faults that cannot be modeled as stuck-at are considered. These feed-through faults, cause the cell to become either data-feed-through, which makes the cell combinational, or clockfeed-thro...
