The geometry of faults is usually thought to be more complicated at the surface than at depth and to control the initiation, propagation and arrest of seismic ruptures1–6. The fault system that runs from southern California into Mexico is a simple strike-slip boundary: the west side of California and Mexico moves northwards with respect to the east. However, the Mw 7.2 2010 El Mayor–Cucapah ear...

ver the past two decades. the growing demand for reliability in indust r i a l p r o c e s s e s h a s d r a w n increasing attention to the problem of fault detection and isolation (FDI), but only a lew studies have b e e n d e d i c a t e d t o t h e r e l a t e d fault-tolerant control (FTC) problem. A fault (abrupt or incipient) is any kind of malfunction or degradation in the plant that ca...

steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. moreover, it is an interface between the diver and vehicle. fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. this paper addresses the fault detection and reconstruction in automotive elect...

Although much has changed in the last few years, mixed-signal design communities have been lethargic to adopt digital Design for Test (DfT), fault simulation, and defect-oriented testing for digital blocks within mixed-signal devices. This inertia is far more evident for complex, mixedsignal devices that resist divide and conquer techniques. Use of digital scan insertion, fault simulation, faul...

Fault diagnosis of induction motors in the practical industrial fields is always a challenging task due to the difficulty that lies in exact identification of fault signatures at various motor operating conditions in the presence of background noise produced by other mechanical subsystems. Several signal processing approaches have been adopted so far to mitigate the effect of this background no...

In this announcement, we report recent results [4] (available at http://arxiv.org/abs/0802. 1123) where we address the open problem of snap-stabilization in message-passing systems. The concept of snap-stabilization [3] offers an attractive approach to transient fault tolerance. As soon as such fault ends a snap-stabilizing protocol immediately operates correctly. Of course, not all safety pred...

The purpose of this paper is to present the fundamentally basic aspects of source spectra through the preliminary use of the one-dimensional Haskell source model which assumes a finite fault with a constant rupture velocity. Teleseismic distances are assumed, such that the far field term dominates, allowing the P and S waves emanating from the source to be effectively considered double couple p...

tern generation (ATPG) has yielded effective solutions for combinational circuits, developing efficient methods for sequential circuits remains difficult. The difficulty results because state and time frame expansion has caused a virtual explosion of the relevant search space. The commonly used branch-and-bound technique1 is infeasible for large sequential circuits because of the exponentially ...

OBJECTIVES To evaluate the relationship between performance-based risk factors and subsequent at-fault motor vehicle collision (MVC) involvement in a cohort of older drivers. DESIGN Prospective cohort study. SETTING Motor Vehicle Administration (MVA) field sites in Maryland. PARTICIPANTS Of the 4,173 older drivers invited to participate in the study, 2,114 individuals aged 55 to 96 agreed...
