In nondestructive testing to locate the faults we send an ultrasonic signal and measure the resulting vibration at di erent points To describe and combine the uncertainty corresponding to di er ent measurements and fuzzy estimates we used fuzzy logic As a result we get reasonably simple computa tional models which lead to as good fault detection as the known more complicated models I Nondestruc...

Transformer overheating faults have an important impact on the transformer safe and stable operation. Taking 10 kV oil-immersed as research object, using indirect coupling analysis method of electromagnetic thermal fluid multi-physical field, heating characteristics under faults, such winding inter-turn short circuit core multi-point grounding, are analysed, abnormal state identification is pro...

Faults in computer networks may result in millions of dollars in cost. Faults in a network need to be localized and repaired to keep the health of the network. Fault management systems are used to keep today’s complex networks running without significant cost, either by using active techniques or passive techniques. In this paper, we propose a novel approach based on imperialist competitive alg...

in current paper, geometrical relationship between the longitudinal faults of a zone of the folded zagros, surrounding asef mountains (north of shiraz) that follow the northwest-southeast structural trend (eg. zarghan, katah and sadra faults) has been studied. a western and southern zone of zagros mountain chain called folded zagros has a length of about 1375 km and a width between 120 and 250 ...

In this paper we present a few fundamental results related to the problems of characterization and detection of intermittent faults in digital circuits, which, up to now, have been almost totally ignored. This problem is important since in many technologies intermittency is a predominant mode of failure. We first discuss various new classes of fault modes. We then introduce a Markov model for a...

Abstract Enabling higher levels of autonomy while ensuring safety requires an increased ability to identify and handle internal faults unforeseen changes in the environment. This article presents approach improve this for a robotic system executing series independent tasks by using dynamic decision network (DDN). A simulation case study industrial inspection drone performing contact-based is us...
