TLDR
A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed in this paper, where tradeoffs in complexity versus performance are discussed, ranging from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, and the development of jump process formulations.Abstract:
A number of methods for detecting abrupt changes (such as failures) in stochastic dynamical systems are surveyed. The class of linear systems is concentrated on but the basic concepts, if not the detailed analyses, carry over to other classes of systems. The methods surveyed range from the design of specific failure-sensitive filters, to the use of statistical tests on filter innovations, to the development of jump process formulations. Tradeoffs in complexity versus performance are discussed.read more

Step-like signal processing with distinct finite number of levels
TL;DR: An algorithm for filtering noisy step-like signals is proposed, based on the assumption of Gaussian contamination, which aims to produce a clean signal with the desired number of discrete amplitudes (levels).

Reliability Bounds for Fault-Tolerant Systems with Competing Responses to Component Failures
TL;DR: In this paper, bounds for the probability of failure of fault-tolerant systems are established in terms of integral factors which depend on component failure rates and the actual distributions of response times.
