Abstract Aiming at the problem of fault location for offshore DC cables, this paper analyses reasons why double-ended method is more accurate than single-ended in transmission lines. We point out that error on cables using mainly comes from fact difference wave speed between different segments ignored. Therefore, based traditional method, proposes an improved traveling ranging which considers v...

A new diagnostic scheme is presented for ball bearing localized faults, which utilizes preprocessed time domain features based pattern recognition (PR). Vibration data is acquired from faulty bearings using a test rig, and the features are extracted from the data segments that are preprocessed prior to use in the fault classification process. The preprocessing involves smoothing of the features...

The very high levels of integration and submicron device sizes used in current and emerging VLSI technologies for FPGAs lead to higher occurrences of defects and operational faults. Thus, there is a critical need for fault tolerance and reconfiguration techniques for FPGAs to increase chip yields (with factory reconfiguration) and/or system reliability (with field reconfiguration). We first pro...

Precast post-tensioned segmental (PPS) bridge piers mitigate global and local damages of structures through natural hinges (joints between their segments) rocking motion segments. The application the PPS is currently growing in Accelerated Bridge Construction (ABC) where segments are manufactured offsite with higher quality, assembled onsite a short time. Structural vulnerability analysis very ...

[1] The Chinese mainland features widespread active faults and intensive seismic activity; both can be described in terms of slip rates on these faults. Previous studies of fault slip rates in mainland China have focused on individual faults or fault segments, and large discrepancies exist among results derived from different methods. Here we derive a self‐consistent estimate of the slip rates ...

Abstract System logs or log files containing textual messages with associated time stamps are generated by many technologies and systems. The clustering technique proposed in this paper provides a tool to discover identify patterns macrolevel events data. motivating application is frequency converters the propulsion system on ship, while general setting fault identification classification compl...

[1] We show that realistic aftershock sequences with space-time characteristics compatible with observations are generated by a model consisting of brittle fault segments separated by creeping zones. The dynamics of the brittle regions is governed by static/kinetic friction, 3D elastic stress transfer and small creep deformation. The creeping parts are characterized by high ongoing creep veloci...

During the great 3 May 1887 Sonoran earthquake (surface rupture end-to-end length: 101.8 km; MW = 7.5±0.3), an array of three north-south striking Basin and Range Province faults (from north to south Pitáycachi, Teras, and Otates) snapped along the western margin of the Sierra Madre Occidental plateau. My detailed fi eld survey of the Teras fault and the 1887 earthquake rupture zone along this ...

Oceanic transform faults are inferred to be weak relative surrounding oceanic crust and primarily slip aseismically. Neither their weakness nor tendency creep well-explained. We test the effects of fault-rock evolution on fault frictional strength stability using direct-shear experiments (at room temperature, 10 MPa normal stress, fluid-saturated conditions) dolerite from East Pacific Rise natu...

One of the remarkable tectonic features of the Earth’s crust is the widespread presence of long, approximately straight and geomorphically prominent strike-slip faults which are a kinematic consequence of large-scale motion of plates on a sphere (Wilson 1965). Strike-slip faults form in continental and oceanic transform plate boundaries; in intraplate settings as a continental interior response...
