Many time-critical applications require predictable performance. Tasks corresponding to these applications have deadlines to be met despite the presence of faults. Failures can happen either due to processor faults or due to task errors. To tolerate both processor and task failures, the copies of every task have to be mutually excluded in space and also in time in the schedule. We assume that e...

Mashhad Plain affects by a series of active faults in the northern margin of the Binalud and the southern margin of the Kopet-Dagh mountain ranges. The activity of these faults forms the morphology of the stepped bedrock of the Plain. In addition, the faults’ activities in the Quaternary period are the main effective parameters in thickness and texture of aquifer deposits in Mashhad Plain. In t...

This paper analyses two different approaches of fault distance location in a double circuit transmission lines, using artificial neural networks. The single and modular artificial neural networks were developed for determining the fault distance location under varying types of faults in both the circuits. The proposed method uses the voltages and currents signals available at only the local end...

This paper presents an application of Wavelet multiresolution analysis (MRA) for the identification and classification of high impedance faults. Daubechies eight (D-8) Wavelet transforms of three phase currents on transmission lines are used for the analysis. The peak absolute values, the mean of the peak absolute values and summation of the 3rd level output of MRA detail signals of current in ...

The traditional approach to fault tolerant computing involves replicating computation units and applying a majority vote operation on individual result bits. This approach, however, has several limitations; the most severe is the resource requirement. This paper presents a new method for fault tolerant computing where for a given error rate, , the hamming distance between correct inputs and fau...

in the last few years, public awareness has been on the increase about short- and long-term effects of forest roads construction on the environment. therefore, forest road managers have to be concerned about the negative impacts and mitigate them as much as possible. this research conducted multi-criteria analysis techniques in a useful way to define the effective criteria and propose a model f...
