Predict and prevent maintenance is routinely carried out. However, how to address the problem of performance assessment maximizing the use of available monitoring data, and how to build a framework that integrates performance assessment, fault detection, and diagnosis are still a significant challenge. For this purpose, this article introduces an approach to performance assessment and fault dia...

S U M M A R Y We examine the characteristics of seismic radiation produced by localized fault-opening and shear motions in a homogeneous solid, along with the effects of having dissimilar solids across the fault on the seismic radiation. The study employs calculations of synthetic seismograms generated at various receiver locations by shear and tensile dislocation sources. The results indicate ...

We investigate the feedbacks between surface processes and tectonics in an extensional setting by coupling a 2-D geodynamical model with a landscape evolution law. Focusing on the evolution of a single normal fault, we show that surface processes significantly enhance the amount of horizontal extension a fault can accommodate before being abandoned in favor of a new fault. In simulations with v...

Background: Once COVID-19 is transmitted, the corresponding civil responsibility should be clarified by the identification of the transmitter, compensation of the damage and detection of the causal relationship between the damage or harm and the harmful act.    Methods: This research has been prepared by descriptive analytical method and its data has been collected by documentary library tools...

Geological forces shape the earth’s crust. Normal faults, for example, form when extensional forces pull blocks of rock apart along a plane, whereas reverse faults are formed by compressional forces. Geologists classify faults to retrace the forces that have acted on an area; however, normal and reverse faults often look similar. In this study we investigated whether viewing superficially simil...

The Cingoli arcuate anticline is part of the Apennines fold-thrust belt in Italy. The anticline nvolves sedimentary carbonate strata generally affected by syn-thrusting contractional tructures such as bed-normal pressure solution seams, folds, and reverse faults. An xception is constituted by an outcrop in the anticline hinge, where sub-horizontal arbonate and chert beds are affected by joints ...

A rolling bearing fault diagnosis method based on the Volterra series and kernel principal component analysis (KPCA) is proposed. In proposed method, first, improved genetic algorithm (IGA) used to identify model of in four states: normal, element fault, inner ring outer fault. The time-domain as feature vector for classify faults. feasibility level verified by experimental results.

BACKGROUND Glutamate is of great importance in food and pharmaceutical industries. There is still lack of effective statistical approaches for fault diagnosis in the fermentation process of glutamate. To date, the statistical approach based on generalized additive model (GAM) and bootstrap has not been used for fault diagnosis in fermentation processes, much less the fermentation process of glu...

An integrated fault diagnosis based fault tolerant longitudinal control system architecture is proposed for civil aircraft which can accommodate partial or total losses of angle of attack and/or calibrated airspeed sensors. A triplex sensor redundancy is assumed for the normal operation of the aircraft using a gain scheduled longitudinal normal control law. The fault isolation functionality is ...

It is widely agreed that building correct fault-tolerant systems is very difficult. To address this problem, this paper introduces a new model-based approach for developing masking fault-tolerant systems. As in component-based software development, two (or more) component specifications are developed, one implementing the required normal behavior and the other(s) the required fault-handling beh...
