Model extraction for fault isolation

2004 IEEE International Conference on Systems, Man and Cybernetics (IEEE Cat. No.04CH37583), 2005
This paper presents a simulation-based approach for fault isolation in complex dynamic systems. A machine learning technique is used to extract, from simulated data, models representing regularities in system behavior. A heuristic based on the degree of coverage of the model on the data is then applied to isolate faults. To test tolerance to incomplete

Fault models for testing in context

1996
We focus in this paper on the problem of modeling faults located in a given component embedded within a composite system. The system is represented as two communicating FSMs, a component FSM and a context machine that models the remaining part of the system which is assumed to be correctly implemented.

Modeling and Testing of Faults in TCAMs

2005
This paper proposes novel fault models for ternary content addressable memories (TCAMs) regarding both physical defects and functional fault models. Novel test algorithms which guarantee high fault coverage and small test length for detecting the faults in high density TCAM cell array is also proposed.

Modeling with extended fault trees

Proceedings. Fifth IEEE International Symposium on High Assurance Systems Engineering (HASE 2000), 2002
In the areas of both safety and reliability analysis, the precise modeling of complex technical systems during their development and for evaluation purposes is of great importance. Traditionally, fault tree models have been used to accomplish this, and, more recently, stochastic Petri-net models have begun to be employed.

Model checking and fault tolerance

1997
We present an algebraic approach to the model checking of fault-tolerant systems. Fault models and fault-handling mechanisms are modelled using special-purpose process operators. Besides providing for natural models, special-purpose operators allow systems with large state spaces to be verified using systems with small state spaces.

Two-dimensional model of a fault

Physical Review A, 1991
We present the results of simulations of a two-dimensional mechanical model of a fault, which is a generalization of the one-dimensional model studied previously [Carlson and Langer, Phys. Rev. A 40, 6470 (1989)]. We incorporate both the lateral fault axis and the fault depth, and consider both cases of spatially homogeneous and depth-dependent ...

Deterministic Models of Communication Faults

2008
In this paper we survey some results concerning the impact of faulty environments on the solvability and complexity of communication tasks. In particular, we focus on deterministic models of faults in synchronous networks, and show how different variations of the model influence the performance bounds of broadcasting algorithms.
