The use of efficient signal processing tools (SPTs) to extract proper indices for the fault detection in induction motors (IMs) is the essential part of any fault recognition procedure. The 2nd part of this two-part paper is, in turn, divided into two parts. Part two covers the signal processing techniques which can be applied to non-stationary conditions. In this paper, all utilized SPTs for n...

As characteristic length scales shrink (<100 nm) in fcc metals, alternative deformation mechanisms not seen in bulk and course-grained material counterparts emerge. In particular in grain sizes on the order of 10s of nanometers, plasticity is mediated by the motion and interaction of partial dislocations and extended stacking faults. Typically, partial dislocations nucleate at grain boundary de...

In this paper we study the problem of detection, classiication and recovery from discrepancies due to faulty modeling of controlled systems. We do this by extending the existing Execution Monitoring mechanism for the high-level robot programming language GOLOG De Giacomo et al., 1998] by introducing a revision technique that transforms the faulty underlying situation calculus theory to a theory...

We use high-resolution earthquake locations to characterize the three-dimensional structure of active faults in California and how it evolves with fault structural maturity. investigate distribution aftershocks several recent large earthquakes that occurred on continental strike slip various maturity (i.e. cumulative displacement, length, initiation age rate). Aftershocks define a tabular zone ...

the zagros fold-and-thrust belt is tectonically active and often has active faults with insensible and slow motions. determining the rate of movement and displacement in these faults requires very precise measurements. one of the measurement methods of fault movements is using geodetic and micro-geodetic studies. this research is focused on one of the active faults in the north of shiraz city, ...

The detection of On-Load Tap-Changer (OLTC) faults at an early stage plays a significant role in the maintenance power transformers, which is most strategic component network substations. Among OLTC fault methods, vibro-acoustic signal analysis known as performant approach with ability to detect many different types. Extracting characteristic features from measured envelopes promising precisely...

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 ...

As space exploration vehicles travel deeper into space, their distance to earth increases. The increased communication delays and ground personnel costs motivate a migration of the vehicle health management into space. A way to achieve this is to use a diagnosis system. A diagnosis system uses sensor readings to automatically detect faults and possibly locate the cause of it. The diagnosis syst...
