Wound-Rotor (WR) resolvers are the most widely used position sensors in applications with harsh environmental conditions. However, their performance is exposed to failure due to the high risk of short circuit (SC) fault. Although the output current of the resolver is negligible, its thin copper wires increase the probability of the short circuit fault. To avoid the propagation of the turn-to-tu...

[1] There are currently two competing models for the frictional strength of the San Andreas Fault in California: the strong-fault model and the weak-fault model. The strongfault model predicts the maximum horizontal compressive stress axis to be at low angles to the fault, while the relatively weak fault model predicts it to be at high angles. Previous studies have disagreed as to which model i...

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...

Bipolar emitter coupled logic (ECL) devices can now be fabricated at very high densities and much lower power consumption. Behavior of two different ECL storage element implementations are examined in the presence of physical faults. While fault models for some implementations of CMOS storage elements have been examined, not much attention has been paid to ECL storage elements. The conventional...

deformation pattern of the northeastern part of the iranian-arabian collision zone (i.e., mainly sanandaj-sirjan belt or zone) is the main concern of this paper. here, we investigate the stress distribution and displacement pattern of eghlid-deh bid area as affected by the position of zagros suture using a three dimensional mechanical model. the modeled area is located between the zagros thrust...

Current design processes are based on top down methodologies, using hardware description languages as the input of the design flow. This trend motivates changes in the test generation and fault simulation processes in order to establish an efficient method to evaluate test strategies at high abstraction levels. To make this possible it is necessary to adopt a fault model compatible with the cir...

The goal of the paper is to propose a set of dedicated fault models targeting single stuck-at faults in hierarchical designs. These include hierarchical fault model for Functional Units, a functional model for multiplexers and a combined hierarchical-functional fault model for conditional operations. In the paper, the new fault models have been integrated to a high-level test path activation to...

When injecting faults in digital systems, most approaches measures only the probability of a fault leading to a failure. This paper addresses the necessity of considering also the fault rates to get reasonable results from the fault injection experiment. For solving this problem we developed a VHDL-based fault injection tool, which allows the correct fault description and which is able to maint...

In this paper, ‎the multi-sensor fault diagnosis in the exhaust temperature sensors of a V94.2 heavy duty gas turbine is presented‎. ‎A Laguerre network-based fuzzy modeling approach is presented to predict the output temperature of the gas turbine for sensor fault diagnosis‎. Due to the nonlinear dynamics of the gas turbine, in these models the Laguerre filter parts are related to the linear d...

In this paper, we propose a software reliability model that considers not only error generation but also fault removal efficiency combined with testing coverage information based on a nonhomogeneous Poisson process (NHPP). During the past four decades, many software reliability growth models (SRGMs) based on NHPP have been proposed to estimate the software reliability measures, most of which ha...
