This paper proposes a new fault model and its modeling and analysis methods in a clockless asynchronous wave pipeline for extensive yield evaluation and assurance. It is highly desirable to have an adequate and specific pulse fault rate model for establishing a sound theoretical foundation for clockless wave pipeline design for reliability. The pulse fault model is thoroughly identified as the ...

In the late nineties, Eli Biham and Adi Shamir published the first paper on Differential Fault Analysis on symmetric key algorithms. More specifically they introduced a fault model where a key bit located in non-volatile memory is forced to 0/1 with a fault injection. In their scenario the fault was permanent, and could lead the attacker to full key recovery with low complexity. In this paper, ...

In order to diagnose transformer fault efficiently and accurately, a dynamic integrated fault diagnosis method based on Bayesian network is proposed in this paper. First, an integrated fault diagnosis model is established based on the causal relationship among abnormal working conditions, failure modes, and failure symptoms of transformers, aimed at obtaining the most possible failure mode. And...

Delay faults are an increasingly important test challenge. Traditional delay fault models are incomplete in that they only model a subset of delay defect behaviors. To solve this problem a combined delay fault (CDF) model has been developed, which models delay faults caused by the combination of spot defects, parametric process variation, and capacitive coupling. The spot defects are modeled as...

Introduction The description of a fault model includes the fault surfaces and associated tip lines, the fault network geometry, and the displacement geometry of faults. Fault surfaces are usually observed from seismic discontinuities, which include reflector breaks, flexures, and amplitude changes. These discontinuities can often have a regular appearance that corresponds to fault geometries fo...

Occurrence of a multiple-points fault in machine operations could result in exhibiting complex fault signatures, which could result in lowering fault diagnosis accuracy. In this study, a multiple-points defect model (MPDM) is proposed which can simulate fault signature’s dynamics for n-points bearing faults. Furthermore, this study identifies that in case of multiple-points fault in the rotary ...

abstract tectonic, plays a key role in the evolution of morphology and can be distinguished with morphotectonic, rivers and structural parameters. an analysis of morphometric parameters illustrates that the development of them is associated with faults activities and rocks resistance. morphotectonic analysis also supplies seismotectonic setting for a region. for appropriate and survey tectonic ...

This paper proposes an ontology model for accurate and efficient transformer fault diagnosis using an explicit, formal and machine-readable format. The model makes use of ontology to represent formally faults and their features such as causes, symptoms, effects, which form a transformer fault diagnosis knowledge base. Moreover, the model can be employed to exchange and reason information for tr...

Although, historically, fault tolerance is connected to safetycritical systems, there has been an increasing interest in fault tolerance in mainstream application such as the cloud. There is a need for formal specification and verification of industrial fault-tolerant designs, since they integrate, in a non-trivial way, the ideas from distributed algorithms, whose correctness is usually based o...

Path selection and generating tests for small delay faults is an important issue in the delay fault area. A novel technique for generating effective vectors for delay defects is the first issue that we have presented in the thesis. The test set achieves high path delay fault coverage to capture small-distributed delay defects and high transition fault coverage to capture gross delay defects. Fu...
