As part of any Prognostics and Health Management (PHM) system for the shipping industry, determination current health marine systems is fundamental. such, diagnostic analytics performed; a process that typically constituted by fault detection, isolation, identification. Although some efforts have been made to distinguish faults malfunctions (fault detection) can occur in systems, implementation...

Various approached have been introduced to extract as much as information form seismic image for any specific reservoir or geological study. Modeling of faults and fractures are among the most attracted objects for interpretation in geological study on seismic images that several strategies have been presented for this specific purpose. In this study, we have presented a modified approach of ap...

Reciprocating compressor (RC) is widely used in industry because of its wide application pressure range, high thermal efficiency and strong adaptability. In order to avoid the possible casualties or property losses caused by fault a RC, it great significance carry out efficient diagnosis for RC. The common types RC usually lead variation range amount air intake, so different faults will changes...

due to their inherent sensitivity to resistivity contrast, em methods have an important role in detection of fault zones. in this paper, we experienced controlled source tensor magnetotelluric (cstmt) method to recognize a fault zone in bam area. an earthquake devastated the town of bam on 26 december 2003. surface displacements reveal that over 2 m of slip occurred at depth on a fault that had...

this paper presents a method for diagnosis of eccentricity fault in a switched-reluctance motor (srm) during offline and standstill modes. in this method, the fault signature is differential induced voltage (div) achieved by injecting diagnostic pulses to the motor windings. it will be demonstrated by means of results that there is a correlation between differential induced voltage and eccentri...

The workflow for the practical application of the automated focusing analysis in time domain is demonstrated by deriving the TTI anisotropy parameters, epsilon and delta, from the previous VTI work in a small portion of the MC Revival survey located in the Mississippi Canyon area. The improvements are achieved for focusing of the dip events, optimized fault plane position, and imaging for base ...

This paper presents results of previous investigations involving 1D and 2D resistivity imaging linear geological structures with varying traverse orientations relative to the structure azimuth a view determining effect such variation on resolution structures. It observed that orientation fault significantly determines while alignment vertical electrical sounding (VES) defines form VES curve lea...

Abstract General faults in regular electrical railways system could be detect by implementing the specific protection functions such as ground fault or sensitive earth fault. Otherwise, in ungrounded electrical railway systems which using both feeding and return contact rail at the same time, fault detection cannot done with above-mentioned function. Due to recent growth in electrical railway ...
