Modeling fault behaviors such as fault occurrences and active/benign durations is an essential step to the design and evaluation of fault-tolerant controller computers. We use a beta-binomial distribution to model fault occurrences both in the presence and in the absence of environmentally-induced (thus common-cause) faults. A multinomial distribution is used to model fault active durations. Th...

Fault slip distributions provide important insight into the earthquake process. We analyze high-resolution along-strike co-seismic slip profiles of the 1992 Mw = 7.3 Landers and 1999 Mw = 7.1 Hector Mine earthquakes, finding a spatial correlation between fluctuations of the slip distribution and geometrical fault structure. Using a spectral analysis, we demonstrate that the observed variation o...

The mathematical modeling of open-switch faults in two-level machine-side converters and the fault-tolerant current control of isotropic permanent-magnet synchronous generators are discussed. The proposed converter model is generic for any open-switch fault and independent of the operation mode of the electrical machine. The proposed fault-tolerant current control system gives improved control ...

An improved fault simulation environment is described in this paper, and details of its faulting capability are presented and tested. The versatility of our fault simulator in handling different fault models by adding new activity functions to our modeling structure such as n-terminal bridge faults is shown. We use our TUFTsim simulator, which is based on concurrent simulation algorithms to eff...

Fault simulation is a powerful yet not well understood tool for generating test vectors. This tutorial describes the principles of fault simulation, fault modeling techniques and the economic benefits of fault simulation. The section on principles of fault simulation includes serial, parallel, and concurrent fault simulation algorithms along with descriptions of digital faults, fault coverage, ...

Abstract In normally consolidated, shallow (depth <~3 km) siliciclastic sequences, faults develop clay smears. Existing models include the dependence of permeability on fraction, but improved predictions fault should account for uncertainty and anisotropy. We introduce PREDICT, a methodology that computes probability distributions directional components (dip-normal, strike-parallel, dip-...
