This paper derives a model of high-voltage overhead power line under fault conditions at low radio frequencies. The derived model is essential for design of communication systems to reliably transfer information over high voltage power lines. In addition, the model can also benefit advanced systems for power-line fault detection and classification exploiting the phenomenon of changed conditions...

Two-pattern test is required to identify delay faults in a circuit. The importance of delay fault testing is increasing gradually because of the fact that traditional stuck-at fault testing is failing to guarantee an acceptable quality level for today’s high-speed chips. Some defects and/or random process variation do not change the steady state behavior of a circuit but affect the at speed per...

Fault recovery of distribution network is realized by operating switches to change topological structure of the network. The final destination of fault recovery is power loss minimization, fault isolation and power load transfer. This article has built the mathematical model of fault recovery considering constraints of node voltage, line capacity and power flow balance. The objective function i...

Studying small repeating earthquakes enables better understanding of fault physics and characterization of fault friction properties. Some of the nearby repeating sequences appear to interact, such as the 'San Francisco' and 'Los Angeles' repeaters on the creeping section of the San Andreas Fault. It is typically assumed that such interactions are induced by static stress changes due to coseism...

shared memory multiprocessors, high availability This report documents a first-cut understanding of the HA issues in DSM systems. We discuss the general HA strategy, advocate for minimizing fault propagation, system reconfiguration time and performance degradation as the distinctive goals for the three stages that the system goes through after the occurrence of a fault till full recovery. We sh...

Early fault diagnosis in complex mechanical systems such as gearbox has always been a great challenge, even with the recent development in deep neural networks. The performance of a classic fault diagnosis system predominantly depends on the features extracted and the classifier subsequently applied. Although a large number of attempts have been made regarding feature extraction techniques, the...

The reliable execution of a mobile agent is a very important design issue in building a mobile agent system and many fault-tolerant schemes have been proposed so far. To further develop mobile agent technology, reliability mechanisms such as fault tolerance and transaction support are required. For this purpose, we first identify two basic requirements for fault-tolerant mobile agent execution:...

Newly emerging safety standards are driving system-on-chip manufacturers to develop better errordetection and correction mechanisms as well as verification environments for their systems. Fault injection in models is one enhancement for verification environments with which chip aging and safety-critical features (e.g., resilience against radiation sensitivity) are verified. SystemC offers the a...

In this paper a new approach to fault diagnosis in an AC motor is introduced. This system combines a neuro-fuzzy system called FasArt (Fuzzy Adaptive System ART based) and the well-known fuzzy k nearest neighbor algorithm. A set of 15 types of non destructive faults has been tested, reaching a high degree of early fault detection and fault type recognition. Moreover, taking into account the neu...

The Swift VO architecture is designed to provide high data rates in support of multimedia type applications in general-purpose distributed environments through the use of distributed striping. Strþing techniques place sections of a single logical data space onto multiple physical devices. The original Swift prototype was designed to validate the architecture, but did not provide fault tolerance...
