Electromagnetic forces in power transformer windings are produced by interaction between the leakage fluxes and current passing them. Since the leakage flux distribution along the windings height is in two axial and radial directions, so the electromagnetic forces have two components, radial and axial. There is a risk that a large electromagnetic force due to the short circuit or inrush current...

Due to the important role of the boiler-turbine units in industries and electricity generation, it is important to diagnose different types of faults in different parts of boiler-turbine system. Different parts of a boiler-turbine system like the sensor or actuator or plant can be affected by various types of faults. In this paper, the effects of the occurrence of faults on the actuators are in...

In a fault-tolerant parallel computer, a functional programming model can facilitate distributed checlq3ointing, error recovery, load balancing, and graceful degradation. Such a model has been implemented on the Draper Fault Tolerant Parallel Processor (FTPP). When used in conjunction with the FrPP's fault detection and masking capabilities, this implementation results in a graceful degradation...

The sources of the May 1202 and November 1759, M 7.5 Near East earthquakes remain controversial, because their macroseismal areas coincide, straddling subparallel active faults in the Lebanese restraining bend. Paleoseismic trenching in the Yammoûneh basin yields unambiguous evidence both for slip on the Yammoûneh fault in the twelfth–thirteenth centuries and for the lack of a posterior event. ...

Cloud Computing is a paradigm that dynamically provides resources as services through the Internet. The constant concern about the trust placed in cloud computing systems inspires dependability studies. A possible way of performing dependability studies, especially regarding reliability and availability, is through fault injection tools, which enable to observe the system’s behavior during the ...

In the past few years, Mobile agent technology is one of the emerging, fastest growing and promising concepts for the development of applications. A mobile agent is composition of computer program that proceed autonomously for a user or application moving in the heterogeneous communication environment. This survey presents “pure fault tolerance technique “that enables a system to continue opera...

Fault detection and isolation are important tasks to improve the protection system of low voltage direct current (LVDC) networks. Nowadays, there challenges related strategies in LVDC systems. In this paper, two proposed methods for fault faulty segment through line bus measurement were discussed. The impacts grid characteristics protective devices under pre-fault normal, under-fault, post-faul...

With the growing demand of Cloud Computing, Fault tolerance is a major concern because there are many types of failure occur and fault tolerance guarantee availability and reliability of critical issues as well as applications. Fault tolerant technique necessary to enable a system to tolerate software faults remaining in the system after its development. When a fault occurs, these techniques pr...

The present paper presents an accurate hybrid framework capable to rapidly detect, classify & locate shortcircuit faults on transmission lines. The proposed algorithm has employed the values resulted from each threephase currents wavelet transform in order to obtain instantaneous fault detection. Singling out short-circuit faults based on the measured voltage waveforms and three-phase current i...
