Transverse basement (TB) faults are important structures in the mountain belts or sedimentary basins influencing various aspects of them. The origin of these faults is diverse, but their effect on the shape and configuration of continental margins is characteristics. The Western Alborz range that borders the South Caspian basin to southwest is a complex range with principal faults and known ear...

the sofeh mountain in the south of isfahan (iran) has a development of shafts (vertical cave). simorgh cave with a depth of 42 m and a length of 52 m has developed along significant fault structures. structural analysis indicates relationships of orientation between the faults and fractures and shafts and chambers geometries. considering the main ne-sw trend of tectonic structures in the area, ...

In this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for V47/660kW wind turbine operated in Manjil wind farm, Gilan province, Iran. According to the acquired data from Iran wind turbine industry, common faults of the wind turbine such as sensor fault...

Abstract Background On September 5, 2022, an Ms 6.8 earthquake occurred in Luding County, Ganzi Tibetan Autonomous Prefecture, Sichuan, China. The casualties and economic losses caused by the are huge. Most of landslides triggered this small medium-sized rock collapses destructive debris flows, with a number large-scale landslides. Results There 5007 coseismic VII-degree area above, total 17.36...

[In St. Louis, in 1883, the population density of 9.8 persons to the acre] is indeed a low density compared with that of most metropolitan cities: that of London, for instance, is given at 52.5 to the acre in 1883. And yet we find the annual rate of mortality per thousand in London in 1883 to have been but 20.4, while that of St. Louis was 21.35. With such a variance existing in the relative de...

This paper presents an algorithm that compacts the Test Sequences generated by a GA-based ATPG program for sequential circuits. In this algorithm, from a set of test sequences, a properly selected subset of sequences is reordered and combined without reducing the number of detected faults. By introducing the metric of fault density sequence selection is guided towards sequences that have higher...

This paper presents an algorithm for adaptive determination of the dead timeduring transient arcing faults and blocking automatic reclosing during permanent faults onoverhead transmission lines. The discrimination between transient and permanent faults ismade by the zero sequence voltage measured at the relay point. If the fault is recognised asan arcing one, then the third harmonic of the zero...

determining the promising area for ore deposits is one of the most important steps of prospecting in regional scales. there are many different methods for identifying these areas including geochemical and geophysical methods, remote sensing and sophisticated statistical methods. based on the theory of spatial relations between the dispersion pattern of ore deposits and metallogenic provinces, m...
