Most fault localization techniques take as input a faulty program, and produce as output a ranked list of suspicious code locations at which the program may be defective. When researchers propose a new fault localization technique, they typically evaluate it on programs with known faults. The technique is scored based on where in its output list the defective code appears. This enables the comp...

Strong background noise and complicated interfering signatures when implementing vibration-based monitoring make it difficult to extract the weak diagnostic features due to incipient faults in a multistage gearbox. This can be more challenging when multiple faults coexist. This paper proposes an effective approach to extract multi-fault features of a wind turbine gearbox based on an integration...

In the integration of GNSS and inertial sensors, any potential sensor failures or faulty measurements due to harsh operating environments or malfunctions of sensor components may result in poorly estimated navigation parameters. If the sensor component failures or faulty measurements occur and cannot be detected immediately, overall system performances will de degraded. Thus, real time detectio...

This paper deals with the diagnosis of induction motors (IM) with the so-called motor current signature analysis (MCSA). The MCSA is one of the most efficient techniques for the detection and the localization of electrical and mechanical failures, in which faults become apparent by harmonic components around the supply frequency. This paper presents a summary of the most frequent faults and its...

We provide test sets proportional to the sum of the two dimensions of the array for a large class of cells, which allow us to test rows (or columns) of cells of the array independently. Constant length test sets for array multipliers have been found under the single faulty cell model if the array is modiied and otherwise test sets are proportional to the number of cells. We can verify the full ...

In case of multiple node failures performance becomes very low as compare to single node failure. Failures of nodes in cluster computing can be tolerated by multiple fault tolerant computing. Existing recovery schemes are efficient for single fault but not with multiple faults. Recovery scheme proposed in this paper having two phases; sequentially phase, concurrent phase. In sequentially phase,...

Redundancy is the traditional technique used to increase system reliability. With modern technology, in addition to being used as temporal redundancy, slack time can also be used by energy management schemes to scale down system processing speed and supply voltage to save energy. In this paper, we consider a system that consists of multiple servers for providing reliable service. Assuming that ...

Handling of multiple simultaneous faults is a complex issue in faulttolerant control. The design task is particularly made difficult by the numerous different cases that need be analyzed. Aiming at safe fault-handling, this paper shows how structural analysis can be applied to find the analytical redundancy relations for all relevant combinations of faults, and can cope with the complexity and ...

Diagnosing multiple faults for a complex system is often very difficult. It requires not only a model which adequately represents the diagnostic aspect of a complex system, but also an efficient diagnostic algorithm that can generate effective test and repair recommendations. One way of developing such an efficient and effective diagnostic algorithm is to focus the computational resource on dis...

A NoC architecture offers high reliability since it has multiple routes from the host to clients. A fault tolerant NoC framework is proposed which achieves maximum performance under fault. NoCs under fault become totally unfunctional. Hence the faulty components are handled separately which ensure that the network is not partitioned and results in high connectivity even under high fault. NoCs a...
