On 16 September 2015, a Mw 8.3 interplate thrust earthquake ruptured offshore the Illapel region (Chile). Here, we perform coseismic slip fault modeling based on multi-orbit Sentinel 1-A (S1A) data. To do this, we generate ascending and descending S1A interferograms, whose combination allows us to retrieve the EW and vertical components of deformation. In particular, the EW displacement map hig...

the theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. in elastic deformation contact occurs over a finite area. a regular method for determining the dimensions of this area is hertz contact model. appearance of atomic force microscope results in introduction of contact mechanics into biology. low elastici...

the study area locates between an active fault system of north anatolian in turkey and active alborz and zagros mountain ranges in iran. the total shortening concluded from arabia-eurasia collision with a rate of 22 mm/year across the ne persia is partitioned  into  two  fault  systems,  right-lateral  strike slip  movements  in  the  turkish-iranian  plateau  like  north tabriz fault system an...

Teleseismic body waveform modeling of the far-field P-and SH-waveforms and spectral analysis of P-waves are used to determine the source parameters of the March 25, 2006 Fin earthquake (mb 5.7). Its epicenter is located at the South of Iran in Hormozgan Province. The waveform modeling results show the earthquake was caused by a thrust motion on a NW-SE striking fault with parameters: Fault plan...

The proposed fault diagnosis approach associates an adaptive observer for residual generation with set-membership computations based on zonotopes for residual evaluation. The main advantage of this approach is its rigorous propagation of pre-specified modeling uncertainty bounds to the computed residuals. Within the assumed modeling uncertainty bounds, fault detection is guaranteed to be free o...

In this paper, we employ the Communicating finite state machine (CFSM) model for networks to investigate fault management using passive testing. First, we introduce the concept of passive testing. Then, we introduce the CFSM model, the observer model and the fault model with necessary assumptions. We introduce the fault detection algorithm using passive testing. Then, we briefly present our new...

This research introduces a new approach to modeling wireless network reliability under diverse fault assumptions. It allows for quantifying reliability and offers potential for modeling survivability. The general model is presented as a join graph of cliques, that allows for horizontal and orthogonal cross-monitoring. This allows for the determination of the maximal potential fault tolerance. T...

Real time and accurate fault detection has attracted an increasing attention with a growing demand for higher operational efficiency and safety of industrial gas turbines as complex engineering systems. Current methods based on condition monitoring data have drawbacks in using both expert knowledge and quantitative information for detecting faults. On account of this reason, this paper proposes...
