In recent years, the fault diagnosis of electro-mechanical robotic systems has been performed in widespread applications, including grand vehicles, unmanned aerial vehicles, and spacecraft. According to the IFAC SAFEPROCESS Technical Committee defined terminology, there is an absolute necessity to identify unexpected changes (faults) in a system before they lead to a complete breakdown (failure...

Regression Testing is basically performed to identify and rectify the client problem after the implementation of software product in client environment. In such case, instead of performing the all testing stages in same way, an intelligent mechanism is been implemented to identify the optimized sequence of test generation. One of such approach is fault analysis based approach. It means the modu...

This paper presents a novel architecture for a fault-tolerant high-performance system using a checkpoint/restart approach with dual modular redundancy (DMR). The proposed architecture can perform low-latency copy with instantaneously copiable SRAM. Furthermore, we can use an instantaneous comparison scheme that has more fault coverage than comparison with a cyclic redundancy check (CRC). Evalua...

Fault control and tolerance in WSN is a challenging problem because of limited energy, bandwidth, and computational complexity. While facing numerous threats these severely resource constrained nodes are responsible for data collection, data processing, localization, time synchronization aggregation and data forwarding. One of the effective approaches to control and tolerate these threats is th...

Roberto Natella Università degli Studi di Napoli Federico II, Italy ABSTRACT This paper proposes an approach to software faults diagnosis in complex fault tolerant systems, encompassing the phases of error detection, fault location, and system recovery. Errors are detected in the first phase, exploiting the operating system support. Faults are identified during the location phase, adopting o...

The electrical system of the construction machinery usually works on circumstance of high temperature, serious vibration and shock, dust pollution as well as electromagnetic interference, so the electrical system is very likely to go wrong while compared with other systems, for example working attachment, under chassis and so on. In view of this, an advanced fault test device, with application ...

Nowadays, inverters are power electronics devices used in the renewable energy conversion systems and also to fed induction motors, therefore the continuity of service of power converter has been a major concern. This paper presents a new approach of open circuit fault detection in a pulse width modulation three phase voltage source inverter. The fault occurrence detection was based on the stan...

—The increasing number of Electro within the network of a vehicle is increa complexity of these networks. Thus, fault sophisticated systems becomes more complex paper is to provide a technique to enable detection in a premium vehicle network or a which uses the Controller Area Network (C communication. The fault detection technique based on a sequential behaviour of the CAN n and by using signa...

This paper presents a wavelet transform and Support Vector Machine (SVM) based algorithm for estimating fault location on transmission lines. The Discrete wavelet transform (DWT) is used for data pre-processing and this data are used for training and testing SVM. Five types of mother wavelet are used for signal processing to identify a suitable wavelet family that is more appropriate for use in...
