introduction iran forms a relatively compact zone of active continental deformation resulted from the northward collision of arabia with eurasia during late cenozoic times, which is continuing to the present-day at a rate of 25 mm/yrs (from gps data). evidences of active tectonic in different parts of iran, has been studied and identified. the arid climate, low rates of erosion, and minimal veg...

Abstract In the presence of an MMC-HVDC system, current differential protection (CDP) has risk failure in operation under internal fault. addition, CDP may also incur security issues transformer (CT) saturation and outliers. this paper, a trajectory image-based algorithm is proposed for AC lines connected to stations using convolution neural network improved by channel attention mechanism (CA-C...

faults/fractures detection is an essential step of the full field study in hydrocarbon reservoir. definition of exact location of these structural events is a critical step to optimize location of the development wells. despite of the fast development of the geo science technology and oil industry in recent years, detection of the small geological events such as faults and fractures in some of ...

For a typical MIMO (Multiple-Input Multiple-Output) nonlinear dynamic system, fault detection and isolation usually aim at process faults with an assumption that actuator faults and sensor faults do not occur at the same time, which is not always the case. This paper uses Extended State Observer for real-time process fault detection and fuzzy inference for fault isolation. It then investigates ...

This paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. The methodology is based on a modified sliding mode observer (SMO) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. The faults are reconstructed using the equivalent output err...

Redundant faults in digital circuits not only result in extra hardware but also mask other faults and may also make undetectable fault detectable. Redundancies increase the chip area, the power consumption, and often propagation delays in the circuit and might even reduce the yield [5]. This paper is a result of literary search for detection and removal of such faults. This paper addresses proc...
