This paper studies the shear zone of North Qazvin fault and investigates the location of rural settlements in this area. In selected sections, the presence of transverse valleys along the fault made it possible to investigate the evidence of shear zones in which we can see severe crushing in igneous rocks of andesitic and trachyandesitic type, and cataclastic. Moreover, traces of faulted and fr...

Fault location is an interesting subject in power grids. On the other hand, the application of fault current limiter (FCL) has been increasing in power network and causes some problems in operation of protection systems. This paper studies the application of FCL in power system and its effect on one-ended simple reactance fault location methods. In these methods, only voltages and currents of t...

Abstract Using mobile agents, it is possible to bring the code close to the resources, which is not foreseen by the traditional client/server paradigm. Compared to the client/server computing paradigm, the greater flexibility of the mobile agent paradigm comes at additional costs as well as the additional complexity of developing and managing mobile agent-based applications. Such complexity ...

In order to evaluate seismic hazard along Qoshadagh Fault (QDF, the causative fault of 11 Aug. 2012 Varzegan- Ahar earthquake), geometric and seismic parameters of the fault were investigated. QDF consists of a central E-W striking, dextral-reverse segment terminating at both ends into NW-SE striking splay arrays. Both eastern and western splay arrays form locally transtensional bends. The NW-S...

In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...
