با توجه به این که در سیستم های صنعتی وقوع fault ممکن است منجر به خرابی کالا، خرابی دستگاه، افت عملکرد و یا تلفات جانی شود، شناسایی و تشخیص به موقع fault و همچنین جبران سازی آن از اهمیت کاربردی بسیار بالایی برخوردار می باشد. عمده ی سیستم های صنعتی را سیستم های غیر خطی و هایبرید با ورودی ها یا حالت های ناهمگون تشکیل می دهند. بنابراین شناسایی fault در این سیستم ها و تلاش برای جبران اثرات آن به کمک...
That faults are of fundamental importance in petroleum systems cannot be stressed enough. The role the faults play, however, is complicated by their dual nature as fluid seals and conduits. Understanding a fault’s behavior demands extensive knowledge of its past geologic history, core samples, pressure measurements, and well logs. Further complicating matters, the sealing capacity of a fault us...
In high-speed and high-throughput packet switches, system reliability is critical to avoid the loss of a huge amount of information and to avoid re-transmission of traffic. We propose a series of concurrent fault-detection mechanisms for a multiple-plane crossbarbased packet switch. Our switch model, called the m z model, has m active planes and z spare planes. This switch has distributed arbit...
S U M M A R Y A model of a ductile fault zone is incorporated into a forward 3-D earthquake model to better constrain fault-zone hydraulics. The conceptual framework of the model fault zone was chosen such that two distinct parts are recognized. The fault core, characterized by a relatively low permeability, is composed of a coseismic fault surface embedded in a visco-elastic volume that can cr...
Recently the wavelength division multiplexing (WDM) networks are becoming prevalent for telecommunication networks. However, even a very short disruption of service caused by network faults may lead to high data loss in such networks due to the high date rates, increased wavelength numbers and density. Therefore, the network survivability is critical and has been intensively studied, where faul...
Fluid injection into rocks is increasingly used for energy extraction and for fluid wastes disposal, and can trigger/induce small- to medium-scale seismicity. Fluctuations in pore fluid pressure may also be associated with natural seismicity. The energy release in anthropogenically induced seismicity is sensitive to amount and pressure of fluid injected, through the way that seismic moment rele...
Observations and modeling of 3- to 6-hertz seismic shear waves trapped within the fault zone of the 1992 Landers earthquake series allow the fine structure and continuity of the zone to be evaluated. The fault, to a depth of at least 12 kilometers, is marked by a zone 100 to 200 meters wide where shear velocity is reduced by 30 to 50 percent. This zone forms a seismic waveguide that extends alo...
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 ...
[1] The 2006 Mw7.0 Mozambique (Machaze) normal-faulting earthquake ruptured an unusually steeply dipping fault plane ( 75°). The amount of slip in the earthquake decreased from depths of 10 km toward the surface, and this shallow slip deficit was at least partly recovered by postseismic afterslip on the shallow part of the fault plane. An adjacent normal fault segment slipped postseismically (a...
