The fault diagnosis of a gearbox is crucial to ensure its safe operation. Entropy has become common tool for measuring the complexity time series. However, entropy bias may occur when data are not long enough or scale becomes larger. This paper proposes method based on Refined Time-Shifted Multiscale Reverse Dispersion (RTSMRDE), t-distributed Stochastic Neighbour Embedding (t-SNE), and Sparrow...

extension of inter-turn fault in windings of pmsm can damage all parts of electrical systems, and in some cases in sensitive applications may lead to irreparable events. identification of such small faults at incipient steps can be so helpful to protect entire part of electrical system. in this paper, intelligent protection system is designed which is made by two major parts. in the first part ...

the sangbast-shandiz fault zone, with a length of about 57 km, a width of moderately 2 km, and a nw-se direction, is located about 15 km in the west of mashhad city. that is one of the major faults in the binalud mountains. geomorphic evidences illustrate that the sangbast-shandiz fault zone has dextral strike- slip offsets with thrust activity. in this article, we investigated geomorphic featu...

The Boumerdes-Algiers earthquake of magnitude Mw:6.8 is the second major event which seriously affected Algeria in the last twenty years. This seismic event, located 7 km north of the village of Zemmouri (50 Km east of Algiers) happened in a region characterized previously by a low to moderate seismic activity. With a depth of 10 km, the earthquake killed 2300 persons and caused huge damage in ...

The notion of reversible computing is attracting interest because of its applications in diverse fields, in particular the study of programming abstractions for fault tolerant systems. Reversible CCS (RCCS), proposed by Danos and Krivine, enacts reversibility by means of memory stacks. Ulidowski and Phillips proposed a general method to reverse a process calculus given in a particular SOS forma...

an attempt has been made to explore the general trends in the seismic response of planasymmetric structures when subjected to near-fault and far-fault ground motions. systems with structural wall elements in both orthogonal directions considering actual and common nonlinear behavior under bi-directional excitation were studied. idealized single-storey models with uni-axial eccentricity were emp...

fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the earth’s crust. furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. in this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...
