The large aircraft engine fault diagnosis in the problem of accurate. General components with different, large aircraft engine structure and its complex, the work in higher frequency failure, failure appear in a relatively short time, and it is difficult to retrieval, leading to establish the connection between the fault occurs when the connection breaks. The traditional fault detection method ...

We have proposed a fault-prone software module detection method using text-filtering approach, called Fault-proneness filtering. Even though the fault-proneness filtering achieved high accuracy in detecting fault-prone modules, the detail of each fault cannot be specified enough. We thus try to complete such weakness of the fault-proneness filtering by using static code analysis. To do so, we a...

In this work an automatic fault classification system is developed for bearing fault classification of three phase induction motor. The system uses the wavelet packet decomposition using ‘db8’ mother wavelet function for feature extraction from the vibration signal, recorded for various bearing fault conditions. The selection of best node of wavelet packet tree is performed by using best tree a...

Many fault injection tools are available for dependability assessment. Although these tools are good at injecting a single fault model into a single system, they suffer from two main limitations for use in distributed systems: (1) no single tool is sufficient for injecting all necessary fault models; (2) it is difficult to port these tools to new systems. NFTAPE, a tool for composing automated ...

We present an approach to design of fault tolerant computing systems. In this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. Code combining techniques are very effective, which one of these codes are turbo codes. The Algorithm-based fault tolerance techniques that to detect errors rely on the c...

PROOFS (Parallel RestOrative Orderindependent Fault Simulator) is a hybrid of concurrent, differential, and parallel fault simulation algorithms. It retains fault dropping advantage of concurrent method, word level parallelism of parallel method and low memory requirement of differential, while minimizing their individual disadvantages. Parallel simulation of faults reduces simulation time of P...

the nw-se trending zagros fold and thrust belt extends for about 1,800 km from a location some 300 km se of the east anatolian fault in ne turkey to the strait of hormuz where the north-south trending zendan-minab-palami fault system (zmp) separates the zagros belt from the makran accretionary prism. the ne limit of the zagros belt is marked by the main zagros reverse fault which is rotated abo...

this research presents a numerical tool to estimate the green's function operator matrix of intraplate faults. having this matrix and its inverse, spatial distribution of fault slippage could be investigated through the inverse analysis of geodetic data. this information could be employed to predict the location of future powerful earthquakes. to implement fault sliding in fe calculations,...

many earthquakes occur in iran every year and some of these earthquakes cause loss of life and property. consequently earthquake is one of challenging topics not only in iran but also in other active tectonic regions in the world. investigating the mechanism of earthquake as a natural disaster is the first and important step. to study earthquakes, different information such as geometry and beha...

AESTRACT We introduce a new fault representation mechanism for digital circuits based on fault tuples. A fault tuple is a simple 3-element condition for a signal line, its value, and clock cyclle constraint. AND-OR expressions of fault tuples are used to represent arbitrary misbehaviors. A fault simulator based on fault tuples was used to conduct experiments on benchmark circuits. Simulation re...
