Abstract - Use of efficient signal processing tools (SPTs) to extract proper indices for fault detection in induction motors (IMs) is the essential part of any fault recognition procedure. The Part1 of the two parts paper focuses on Fourier-based techniques including fast Fourier transform and short time Fourier transform. In this paper, all utilized SPTs which have been employed for fault fete...

Pull-apart basins are faulting and folding zones with high intensity of fractures that strongly affect the production in unconventional shale gas. While most observations pull-apart were from surface mapping or laboratory experiments, we investigated a nascent basin subsurface. We characterized along strike-slip fault within Woodford Shale by using seismic attributes analyses, including coheren...

Carbon sequestration has recently become more widely recognized as a potential means of reducing atmospheric carbon dioxide levels. Understanding the tectonic relationship discharges and sealing behavior faults is conducive for predicting long-term integrity geological storage formations. Of primary concern influence crustal deformation on leakage through fault zones during large-scale undergro...

This work summarizes our recent findings on hydraulic fracturing-induced seismicity nucleated in the Duvernay shale reservoirs within Western Canada Sedimentary Basin. A coupled model of in-situ stress and fracture-fault systems was built to quantify four-dimensional pressure changes spatiotemporal nucleation during fracturing. Five triggering mechanisms were successfully recognized seismicity-f...

The most enigmatic problems with the nearly 200 salt domes pierced in the Persian Gulf and in the Zagros Mountain Ranges (ZMR) in southern Iran, a unique morphology in the world, have been the matter of this study, which is based on a combination of field work, enhancement of satellite and aerial photographs etc. In the ZMR, structural anomalies are frequently associated with similar facies dis...

the zagros fold-and-thrust belt is tectonically active and often has active faults with insensible and slow motions. determining the rate of movement and displacement in these faults requires very precise measurements. one of the measurement methods of fault movements is using geodetic and micro-geodetic studies. this research is focused on one of the active faults in the north of shiraz city, ...

As part of the European ACT-sponsored research consortium, DETECT, we developed an integrated characterisation and risk assessment toolkit for natural fault/fracture pathways. In this paper, describe DETECT experimental-modelling workflow, which aims to be predictive fault-related leakage quantification, its application a field case example validation. The workflow combines laboratory experimen...

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...

background: posttraumatic and/or postsurgical knee stiff ness is one of the orthopedic complications which is difficult to be treated and can affect individual’s life negatively. the aim of this study is to investigate the results of quadricepsplasty in patients with knee stiff ness resulted from femoral fracture. materials and methods: this is a cross-sectional study on all patients with femor...
