Identification of feedback bridging faults with oscillation

Proceedings Eighth Asian Test Symposium (ATS'99), 2003
When a feedback bridging fault occurs in a combinational circuit and it is activated, logical oscillation may be generated in the circuit. In this paper, the necessary conditions are presented for feedback bridging faults to generate logical oscillation. Also, a method is proposed to identify such faults in feedback bridging ones.

Identification of undetectable faults in combinational circuits

Proceedings 1989 IEEE International Conference on Computer Design: VLSI in Computers and Processors, 2003
Identification of undetectable faults is essential for preventing test invalidation due to the occurrence of such faults, and for improving the efficiency of test generation. Methods for identifying undetectable faults in combinational circuits by analyzing regions between fanout stems and reconvergent gates are presented.

Novel Coding for PON Fault Identification

IEEE Communications Letters, 2011
In this paper we propose a novel simple periodic optical encoder for centralized fault monitoring of fiber-to-the-X (FTTX) passive optical networks (PONs). This optical encoder exploits a fiber ring with a different length for each distribution/drop fiber to produce a different periodic code.

Fault detection: a subspace identification approach

Proceedings of the 40th IEEE Conference on Decision and Control (Cat. No.01CH37228), 2002
Some results on the analysis of the fault detection problem in a subspace identification framework are presented and two approaches are proposed, exploiting an existing perturbation analysis of subspace methods.

Fault Reconstruction and Identification

2012
This chapter introduces fault reconstruction and identification methods, particularly for those processes whose data follow non-Gaussian distributions. For non-Gaussian fault detection, recent work has demonstrated the effectiveness of Independent Component Analysis (ICA) to extract non-Gaussian source signal and Support Vector Data Description (SVDD ...

On minimizing testing rounds for fault identification

[1988] The Eighteenth International Symposium on Fault-Tolerant Computing. Digest of Papers, 2003
A bound is obtained for the number of rounds of testing sufficient to identify the faulty units of a system. Within a single round each unit may participate in at most one test. The authors give an adaptive algorithm which works in O(log/sub (n/t)//sup t/) rounds and uses O(n) tests.

Fault Identification Techniques

2013
Fault identification can be considered as an important objective of a fault diagnosis framework. The identification result helps fault isolation through comparing the estimated parameter values with their nominal ones. In addition, the estimated size of faults can provide useful information to achieve fault tolerant control.

Fault identification and routing in Benes networks

Journal of Systems Architecture, 1996
Abstract An N × N Benes network B ( n ) ( n = log 2 N ), being a rearrangeable network, can realize any N × N permutation in a single pass. But even in the presence of a single switch fault in B ( n ), two passes are necessary to realize any N × N permutation. In this paper, we attempt to characterize the switch fault sets in B ( n )

Nonlinear Multiscale Fault Detection and Identification

IFAC Proceedings Volumes, 2006
Abstract A nonlinear multiscale multivariate statistical process control method is proposed to address fault detection and diagnosis issues at different scales in nonlinear processes. A kernel principal component analysis (KPCA) model is built with the reconstructed data obtained by performing wavelet transform and inverse wavelet transform ...

Distributed fault identification in telecommunication networks

Journal of Network and Systems Management, 1995
Telecommunications networks are often managed by a large number of management centers, each responsible for a logically autonomous part of the network. This could be a small subnetwork such as an Ethernet, a Token Ring or an FDDI ring, or a large subnetwork comprising many smaller networks. In response to a single fault in a telecommunications network,
