In this chapter, the main types of faults are first reviewed and linear time-invariant plant models with additive faults are introduced. These models represent the basis of the synthesis approaches of fault detection filters presented in this book. Models with fictive noise inputs can be used to account for the effects of parametric variations.

Facies Modelling in Fault Zones
ECMOR X - 10th European Conference on the Mathematics of Oil Recovery, 2006Traditionally fault impact on fluid flow is included by assigning transmissibility multipliers to flow simulation grid cell faces co-located with the fault plane (Manzocchi et al. 1999). A new method, called Fault Facies modelling (Tveranger et al. 2004, 2005), captures fault impact by considering faults as deformed rock volumes rather than simple ...

On probabilistic modeling in fault detection
1999 European Control Conference (ECC), 1999This paper provides a unified background of probabilistic modeling methods which should serve to model-based fault detection (FD). This background should help in orientation within within the set of the problems to be addressed when developing a novel method as well as within a wide set of available methods and in recognition of their suitability to a ...

Proceedings of IEEE VLSI Test Symposium, 2002
This paper analyses the general problem of the determination of the intermediate potentials created by a bridging fault. The analyses is made taking into account the bridge resistance value. It is shown that the fault is detectable as a logic error for a given range of bridge resistance values.

Physical Fault Models and Fault Tolerance
2009Dependable systems are obtained by means of extensive testing procedures and the incorporation of fault tolerance mechanisms encompassing error detection (on-line testing) and system recovery. In that context, the characterization of fault models that are both tractable and representative of actual faults constitute an essential basis upon which one ...

Finding defects with fault models
Proceedings of 1995 IEEE International Test Conference (ITC), 2002A process is presented to validate fault models used in fault diagnosis. Known defects are inserted, using a focused ion beam (FIB), into production ICs and their behavior is compared to that predicted in fault simulation. The fault model is refined until it matches the observed defect behavior.

Modelling the fault correction process
Proceedings 12th International Symposium on Software Reliability Engineering, 2005In general, software reliability models have focused on modeling and predicting failure occurrence and have not given equal priority to modeling the fault correction process. However, there is a need for fault correction prediction, because there are important applications that fault correction modeling and prediction support.

Modeling the effort to correct faults
Journal of Systems and Software, 1995Abstract An approach is proposed for analyzing the determinants of fault locality and fault correction effort during unit, system, and acceptance testing. The approach uses a Poisson analysis to model fault locality and a categorical multivariate regression analysis based on an ordered response model to model effort.

A software cascading faults model
Science China Information Sciences, 2011Functions and call relations are extracted into nodes and edges, respectively, by which a novel topological model is proposed. The directional edges and the corresponding weight values express the call relations and tightness degree. By introducing two concepts of function fault-tolerant capability and software fault intensity and by designing a ...
