in this study, the development of structural elements and the relationship between these elements and dikes emplacements investigated by the field surveys and analysis of satellite images of the east dasht-e bayaz fault zone. in this area nnw-sse (t2) and nw-se trending dikes are which follow the fractures of the region. we measured geometric characters of dikes (such as thickness, attitude, di...

the nw-se trending tus fault is one of the active faults in the north-east of iran . geomorphologic evidences indicate that this fault is active and goes through mashhad city from near tus town. since the population and number of pilgrims in this city are high, the study of the tus fault is of great importance. hence, we have carried out a new investigation to evaluate the hazardous potential o...

Low stacking fault energy face centered cubic (FCC) materials contain characteristic defect structures. Stacking fault tetrahedral are one of those rare structures that occur under special experimental conditions. For the first time, stacking fault tetrahedral were observed in Fe-30Mn-3Al-3Si twinning induced plasticity (TWIP) steel. Their presence resulted from a quenching heat treatment.

in this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4),  ferromagnetic ising system consisting of magnetic atoms with spin-1. this study is done using the effectivefield theory (eft) with correlations method. the equations are derived using...

The North Tabriz Fault is seismologically an active fault with current right lateral strike-slip movements. Restricted mafic to intermediate Late Cretaceous igneous rocks are exposed along the North Tabriz Fault. Whole rock samples and clinopyroxene phenocrysts geochemistry were studied in order to characterize the petrogenesis of these mafic rocks and their possible relation to an oceanic crus...

In this paper, an approach is proposed for accurate locating of single phase faults in transmission lines using voltage signals measured at one-end. In this method, harmonic components of the voltage signals are extracted through Discrete Fourier Transform (DFT) and are normalized by a transformation. The proposed fault locator, which is designed based on Random Forests (RF) algorithm, is train...
