Aiming at the problems existing in fault diagnosis of Distributed micro gas turbine, a kind of new information system frame of fault Diagnosis on Distributed micro gas turbine is proposed in this paper. The consumers and the manufactures contact with each other through Internet, share the corresponding data of the Distributed Micro-turbine, and diagnose and solve the faults together. Through th...

steering assist system controls the force transfer behavior of the steering system and improves the steering probability of the vehicle. moreover, it is an interface between the diver and vehicle. fault detection in electrical assisted steering systems is a challenging problem due to frequently use of these systems. this paper addresses the fault detection and reconstruction in automotive elect...

In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...

Three phase induction motors have many applications in industries. Consequently, detecting and estimating the fault and compensate it in a way that the faulty induction motor satisfies the predefined goals are important issues. One of the most common faults in induction motors is the short circuit of the stator winding. In this paper, an active fault-tolerant control system is designed and pres...

Fault zone structures at many scales largely dictate earthquake ruptures and are controlled by the geologic setting slip history. Characterizations of these diverse inform better understandings hazards phenomenology. However, characterizing fault zones sub-kilometer has historically been challenging, challenges exacerbated in urban areas, where locating faults is critical for hazard assessment....

آثار فعالیت های نوزمین ساختی گسل شمال تبریز به صورت انواع مختلف نشانگرهای تکتونیک فعال در طول پرتگاههای آن قابل مشاهده است. در این پژوهش ابتدا گسل شمال تبریز به سه پاره اصلی و بر مبنای پارامترهای ساختاری و لرزه زمین ساختی پاره بندی شده است. سپس وضعیت تنش دیرین مورد بررسی قرار گرفته و میدان تنش دیرین بازسازی شده است. پس از گردآوری داده های گسل- خش لغزش تحلیل تنش دیرین با روش وارون سازی انجام شده...

In this paper, a new method for extracting dynamic properties for High Impedance Fault (HIF) detection using discrete Fourier transform (DFT) is proposed. Unlike conventional methods that use features extracted from data windows after fault to detect high impedance fault, in the proposed method, using the disturbance detection algorithm in the network, the normalized changes of the selected fea...
