Cascading overload failures occurred in power systems due to higher penetration of renewable energy resources (RERs), which causes uncertainty a grid. To overcome these cascading failures, proper assessment the form load flow balancing and transients stability is required integrated grids (RIPGs). This problem becomes more critical occurrence multiple intervals faults interconnected RIPGs, trip...

The Network Diagnostic System (NDS) is an ARBY based expert system for fault isolation in a nationwide communications network (COMNET). Due to both the structure and function of the network, failures in COMNET are often multiple component failures (either dependent or independent) or intermittent failures. The maintenance procedure for isolating and correcting faults in COMNET exploits multiple...

In this paper an on-line multiple faults detection approach is proposed and improved by the use of Particle Swarm Optimization (PSO) to optimally adjust the membership functions parameters. The residuals obtained by Analytical Redundancy Relations are used as inputs to our system. The Analytical Redundancy Relations are generated by the use of bond graph modelling. The results of the fuzzy dete...

Logic reasoning approaches to fault diagnosis account for the fact that a component cj may fail intermittently by introducing a parameter gj that expresses the probability the component exhibits correct behavior. This component parameter gj , in conjunction with a priori fault probability, is used in a Bayesian framework to compute the posterior fault candidate probabilities. Usually, informati...

A similarity network is a tool for constructing belief networks for the diagnosis of a single fault. In this paper, we examine modifications to the similaritynetwork representation that facilitate the construction of belief networks for the diagnosis of multiple coexisting faults.

This paper deals with the diagnostic design of an Inertial Measurement Unit (IMU). IMU are widely used for system positioning. Their goal is to sense the attitude (or orientation) of a rigid body on which the IMU is embedded. In this paper, the sensors used in the IMU are a tri-axis accelerometer, a tri-axis magnetometer and 3 rate gyros. The diagnostic method proposed in this paper is independ...

In today's competitive IC market, success often means delivering the shortest possible clock cycle. Under pressure to push increasingly complex processing technologies to the limits, designers are delivering circuits with decreased timing and noise margins. In doing so, they are making the circuits significantly more susceptible to manufacturing imperfections. In particular, previously benign m...

In this paper, we show two process allocation schemes to tolerate multiple faults when the primary-backup replication method is used. The rst scheme, called multiple backup scheme, is running multiple backup processes for each process to tolerate multiple faults. The second scheme, called regenerative backup scheme, is running only one backup process for each process, but regenerates backup pro...

{ This paper introduces the concept of detectable perturbations as a method to generate tests that can then cover any technology-speciic faults such as multiple bridging , open and stuck-at faults. Rather than devising a cus-tomized test pattern generation system for each class of technology-speciic faults, we implemented a generic system to generate tests for single and multiple perturbations....
