A fault-tolerant gait of multi-legged systems is defined as a gait which can maintain the gait stability and continue its walking against the occurrence of a leg failure (Yang & Kim, 1998). The notion of the fault-tolerant gait comes from the fact that legged robots with static walking have inherent fault tolerance capability against a failure in a leg, since a failed leg for itself does not ca...

A cluster of sensor nodes in Cluster-based Wireless Sensor Network (CWSN) is cooperating to achieve some objectives. For CWSN, the fault-tolerance and reliability has been an important topic. The problem of reaching agreement in the distributed system is one of the most important issues to design a fault-tolerance system. In previous works, reach a common agreement among healthy nodes to cope w...

We present a two-dimensional analytical solution for the static stress field around rough interlocked interface under background stresses and its applications to faulting. The is derived using perturbation theory defined topography stresses. failure-ratio, which scales likelihood failure of bulk material interface, calculated adopting Coulomb criterion. compare model predictions with results ex...

The main research intent of this paper is to introduce the use of fault tree analysis (FTA) and failure mode and effects analysis (FMEA) in conjunction to analyse the risk and reliability of a complex mechatronic system in both qualitative and quantitative manner. The major focus is on handling imprecise and vague information with the help of fuzzy synthesis of information. A complex mechatroni...

This paper defines the fault-tolerant mutual exclusion problem in a message-passing asynchronous system and determines the weakest failure detector to solve the problem. This failure detector, which we call the trusting failure detector, and which we denote by T , is strictly weaker than the perfect failure detector P but strictly stronger than the eventually perfect failure detector P . The pa...

This paper presents the design of Coactive Adaptive Neuro-Fuzzy Observer based sensor fault detection and fault tolerant control under sensor failure conditions for a three-tank interacting level process. Fault detection is performed by estimating the states of the level process and comparing them with measured values. A fault is signaled when the difference between the estimated and measured v...

development of monitoring systems to fault detection, in offensive and defensive systems, uav, aircraft and other complex systems technically make it possible and favorable, predictive diagnosis of faults. health management model and predict equipment failures (phm) were created in recent years by formation a strong bond of science in engineering, computer and reliability. for this reason, more...

Fault tree analysis, the most widely used safety analysis technique in industry, is often applied manually. Although techniques such as cutset analysis or probabilistic analysis can be applied on the fault tree to derive further insights, they are inadequate in locating flaws when failure modes in fault tree nodes are incorrectly identified or when causal relationships among failure modes are i...

Debugging programs is a complicated and cumbersome task. It is an iterative process which includes hypothesizing the cause of a failure and validating the hypothesis. Since programs comprise of many components with complex interactions this chain often involves several trials. Fault localization (FL) is the task of identifying components that are likely to cause the failure. Automated fault loc...
